Beyond pairwise mechanisms of species coexistence in complex communities

Nature, Vol. 546, No. 7656. (31 May 2017), pp. 56-64,


The tremendous diversity of species in ecological communities has motivated a century of research into the mechanisms that maintain biodiversity. However, much of this work examines the coexistence of just pairs of competitors. This approach ignores those mechanisms of coexistence that emerge only in diverse competitive networks. Despite the potential for these mechanisms to create conditions under which the loss of one competitor triggers the loss of others, we lack the knowledge needed to judge their importance for coexistence in nature. ...


Divergence of species responses to climate change

Science Advances, Vol. 3, No. 5. (17 May 2017), e1603055,


Climate change can have profound impacts on biodiversity and the sustainability of many ecosystems. Various studies have investigated the impacts of climate change, but large-scale, trait-specific impacts are less understood. We analyze abundance data over time for 86 tree species/groups across the eastern United States spanning the last three decades. We show that more tree species have experienced a westward shift (73%) than a poleward shift (62%) in their abundance, a trend that is stronger for saplings than adult trees. The ...


Hybrid incompatibility caused by an epiallele

Proceedings of the National Academy of Sciences, Vol. 114, No. 14. (04 April 2017), pp. 3702-3707,


[Significance] Deleterious mutations in different copies of a duplicated gene pair have the potential to cause hybrid incompatibility between diverging subpopulations, contributing to reproductive isolation and speciation. This study demonstrates a case of epigenetic gene silencing rather than pseudogene creation by mutation, contributing to a lethal gene combination on hybridization of two ecotypes of Arabidopsis thaliana. Our findings provide direct evidence that naturally occurring epigenetic variation can contribute to incompatible hybrid genotypes, reducing gene flow between subtypes of the same species. [Abstract] Hybrid incompatibility ...


Fitness of multidimensional phenotypes in dynamic adaptive landscapes

Trends in Ecology & Evolution, Vol. 30, No. 8. (August 2015), pp. 487-496,


[Highlights] [::] Integrating fitness into community ecology will improve trait-based predictions. [::] Dynamic adaptive landscapes link phenotypes to fitness across environments. [::] Fitness is a function of multidimensional phenotype–environment interactions. [::] Intraspecific trait covariation constrains environmental niche breadth. [Abstract] Phenotypic traits influence species distributions, but ecology lacks established links between multidimensional phenotypes and fitness for predicting species responses to environmental change. The common focus on single traits rather than multiple trait combinations limits our understanding of their adaptive value, and intraspecific trait covariation has been neglected in ...


Evolutionary and plastic responses to climate change in terrestrial plant populations

Evolutionary Applications, Vol. 7, No. 1. (January 2014), pp. 123-139,


As climate change progresses, we are observing widespread changes in phenotypes in many plant populations. Whether these phenotypic changes are directly caused by climate change, and whether they result from phenotypic plasticity or evolution, are active areas of investigation. Here, we review terrestrial plant studies addressing these questions. Plastic and evolutionary responses to climate change are clearly occurring. Of the 38 studies that met our criteria for inclusion, all found plastic or evolutionary responses, with 26 studies showing both. These responses, ...


Genetic divergence in forest trees: understanding the consequences of climate change

Functional Ecology, Vol. 28, No. 1. (February 2014), pp. 22-36,


[::] Predicted climate change is heading in many respects into untested environmental conditions for trees and to the reshuffling of species distributions. We explore the consequences that these changes are likely to have on population differentiation of adaptive traits. Superimposed on the spatial redistribution of the species, will there be a redistribution of their genetic variation? [::] We base our predictions on a conceptual framework, whose elements are the extant differentiation, and the predicted divergent evolution of populations along purposely chosen altitudinal/latitudinal ...


Intraspecific trait variation across scales: implications for understanding global change responses

Global Change Biology, Vol. 22, No. 1. (January 2016), pp. 137-150,


Recognition of the importance of intraspecific variation in ecological processes has been growing, but empirical studies and models of global change have only begun to address this issue in detail. This review discusses sources and patterns of intraspecific trait variation and their consequences for understanding how ecological processes and patterns will respond to global change. We examine how current ecological models and theories incorporate intraspecific variation, review existing data sources that could help parameterize models that account for intraspecific variation in ...


A review of the combination among global change factors in forests, shrublands and pastures of the Mediterranean Region: beyond drought effects

Global and Planetary Change, Vol. 148 (January 2017), pp. 42-54,


[Highlights] [::] Different global change factors combine causing unprecedented ecological effects. [::] Much more complex interactions arise when combinations occur together. [::] Drought should be considered when designing and applying management policies. [::] Conserving Mediterranean terrestrial ecosystems is a collective effort. [Abstract] Climate change, alteration of atmospheric composition, land abandonment in some areas and land use intensification in others, wildfires and biological invasions threaten forests, shrublands and pastures all over the world. However, the impacts of the combinations between global change factors are not well understood despite ...


Viewing forests through the lens of complex systems science

Ecosphere, Vol. 5, No. 1. (January 2014), art1,


Complex systems science provides a transdisciplinary framework to study systems characterized by (1) heterogeneity, (2) hierarchy, (3) self-organization, (4) openness, (5) adaptation, (6) memory, (7) non-linearity, and (8) uncertainty. Complex systems thinking has inspired both theory and applied strategies for improving ecosystem resilience and adaptability, but applications in forest ecology and management are just beginning to emerge. We review the properties of complex systems using four well-studied forest biomes (temperate, boreal, tropical and Mediterranean) as examples. The lens of complex systems ...


Predictors of elevational biodiversity gradients change from single taxa to the multi-taxa community level

Nature Communications, Vol. 7 (22 December 2016), 13736,


The factors determining gradients of biodiversity are a fundamental yet unresolved topic in ecology. While diversity gradients have been analysed for numerous single taxa, progress towards general explanatory models has been hampered by limitations in the phylogenetic coverage of past studies. By parallel sampling of 25 major plant and animal taxa along a 3.7 km elevational gradient on Mt. Kilimanjaro, we quantify cross-taxon consensus in diversity gradients and evaluate predictors of diversity from single taxa to a multi-taxa community level. While single ...


Complex responses to global change at alpine treeline

Physical Geography, Vol. 22, No. 4. (1 July 2001), pp. 333-342,


A focus of geography is the study of complexity: we include many interacting processes when we study places. Another view of complexity in geography is that complex pattern, in particular spatial pattern, can arise from few or simple interactions, if they are nonlinear. Environmental responses to global change are likely to be nonlinear and thus complex. Shifts in ecotones–the boundaries of vegetation types or biomes–may be indicative of such complex response to global change. One reason for expecting nonlinearity is that ...


Framework for making better predictions by directly estimating variables’ predictivity

Proceedings of the National Academy of Sciences, Vol. 113, No. 50. (13 December 2016), pp. 14277-14282,


[Significance] Good prediction, especially in the context of big data, is important. Common approaches to prediction include using a significance-based criterion for evaluating variables to use in models and evaluating variables and models simultaneously for prediction using cross-validation or independent test data. The first approach can lead to choosing less-predictive variables, because significance does not imply predictivity. The second approach can be improved through considering a variable’s predictivity as a parameter to be estimated. The literature currently lacks measures that do ...


Random forests

Machine Learning, Vol. 45, No. 1. (2001), pp. 5-32,


Random forests are a combination of tree predictors such that each tree depends on the values of a random vector sampled independently and with the same distribution for all trees in the forest. The generalization error for forests converges a.s. to a limit as the number of trees in the forest becomes large. The generalization error of a forest of tree classifiers depends on the strength of the individual trees in the forest and the correlation between them. Using a random ...

Sequential disturbance effects of hailstorm and fire on vegetation in a Mediterranean-type ecosystem

Ecosystems, Vol. 18, No. 7. (2015), pp. 1121-1134,


Frequency and intensity of disturbance is projected to increase for many ecosystems globally, with uncertain consequences, particularly when disturbances occur in rapid succession. We quantified community response (52 shrub species and the tree Eucalyptus todtiana) to a severe hailstorm followed 2 months later by prescribed fire for a Mediterranean-type shrubland in southwestern Australia. Partial overlap of hailstorm path and fire perimeter provided a unique opportunity to compare storm and fire effects along a storm severity gradient (high–moderate–none) with and without fire. ...


Ten steps to programming mastery



[Excerpt] Here are ten ways you can improve your coding. The overriding principle to improving your skill at coding, as well as almost endeavor, is open your mind and then fill it with better knowledge. Improvement necessarily implies change, yet it is human nature to fear and resist change. But overcoming that fear and embracing change as a way of life will enable you to reach new levels of achievement. [...] [::Big Rule 1: Break your own habits] When you began coding, you were much less experienced ...


Welcome to postnormal times

Futures, Vol. 42, No. 5. (20 June 2010), pp. 435-444,


All that was ‘normal’ has now evaporated; we have entered postnormal times, the in-between period where old orthodoxies are dying, new ones have not yet emerged, and nothing really makes sense. To have any notion of a viable future, we must grasp the significance of this period of transition which is characterised by three c's: complexity, chaos and contradictions. These forces propel and sustain postnormal times leading to uncertainty and different types of ignorance that make decision-making problematic and increase risks ...


Risk of multiple interacting tipping points should encourage rapid CO2 emission reduction

Nature Climate Change, Vol. 6, No. 5. (21 March 2016), pp. 520-525,


Evidence suggests that several elements of the climate system could be tipped into a different state by global warming, causing irreversible economic damages. To address their policy implications, we incorporated five interacting climate tipping points into a stochastic-dynamic integrated assessment model, calibrating their likelihoods and interactions on results from an existing expert elicitation. Here we show that combining realistic assumptions about policymakers’ preferences under uncertainty, with the prospect of multiple future interacting climate tipping points, increases the present social cost of ...


Climate, CO2 and human population impacts on global wildfire emissions

Biogeosciences, Vol. 13, No. 1. (15 January 2016), pp. 267-282,


Wildfires are by far the largest contributor to global biomass burning and constitute a large global source of atmospheric traces gases and aerosols. Such emissions have a considerable impact on air quality and constitute a major health hazard. Biomass burning also influences the radiative balance of the atmosphere and is thus not only of societal, but also of significant scientific interest. There is a common perception that climate change will lead to an increase in emissions as hot and dry weather ...


Relationships between human population density and burned area at continental and global scales

PLoS ONE, Vol. 8, No. 12. (16 December 2013), e81188,


We explore the large spatial variation in the relationship between population density and burned area, using continental-scale Geographically Weighted Regression (GWR) based on 13 years of satellite-derived burned area maps from the global fire emissions database (GFED) and the human population density from the gridded population of the world (GPW 2005). Significant relationships are observed over 51.5% of the global land area, and the area affected varies from continent to continent: population density has a significant impact on fire over most ...


Defining pyromes and global syndromes of fire regimes

Proceedings of the National Academy of Sciences, Vol. 110, No. 16. (16 April 2013), pp. 6442-6447,


Fire is a ubiquitous component of the Earth system that is poorly understood. To date, a global-scale understanding of fire is largely limited to the annual extent of burning as detected by satellites. This is problematic because fire is multidimensional, and focus on a single metric belies its complexity and importance within the Earth system. To address this, we identified five key characteristics of fire regimes—size, frequency, intensity, season, and extent—and combined new and existing global datasets to represent each. We ...


System crash as dynamics of complex networks

Proceedings of the National Academy of Sciences, Vol. 113, No. 42. (18 October 2016), pp. 11726-11731,


[Significance] System crash, as an essential part of system evolution, sometimes happens in peculiar manners: Weakened systems may survive for a surprisingly long time before suddenly meeting their final ends, whereas seemingly unbeatable giants may drastically crash to virtual nonexistence. We propose a model that describes system crash as a consequence of some relatively simple local information-based individual behaviors: Individuals leave networks according to some most straightforward assessment of current and future benefits/risks. Of note, such a simple rule may enable a ...


Simple dynamical models capturing the key features of the Central Pacific El Niño

Proceedings of the National Academy of Sciences, Vol. 113, No. 42. (18 October 2016), pp. 11732-11737,


[Significance] The Central Pacific El Niño (CP El Niño) has been frequently observed in recent decades. The phenomenon is characterized by an anomalous warm sea surface temperature (SST) confined to the central Pacific and has different teleconnections from the traditional El Niño with major societal impact. Here, a simple modeling framework is developed and shown to capture the key mechanisms of the CP El Niño. In addition to the SST, other major characteristics of the CP El Niño such as the rising ...


Meteorology: air particles boost rain extremes

Nature, Vol. 537, No. 7620. (14 September 2016), pp. 282-282,


[Excerpt] As the climate warms, tiny particles suspended in the atmosphere may have a greater effect than greenhouse gases on increasing the frequency of extreme rain and snowfall. [\n] Greenhouse gases and atmospheric aerosols both drive extreme precipitation, which is expected to increase with climate change. [...] ...


Sensitivity of precipitation extremes to radiative forcing of greenhouse gases and aerosols

Geophys. Res. Lett., Vol. 43, No. 18. (28 September 2016), 2016GL070869,


Greenhouse gases (GHGs) and aerosols are the two most important anthropogenic forcing agents in the 21st century. The expected declines of anthropogenic aerosols in the 21st century from present-day levels would cause an additional warming of the Earth's climate system, which would aggravate the climate extremes caused by GHG warming. We examine the increased rate of precipitation extremes with global mean surface warming in the 21st century caused by anthropogenic GHGs and aerosols, using an Earth system model ensemble simulation. Similar ...


Wildland fire as a self-regulating mechanism: the role of previous burns and weather in limiting fire progression

Ecological Applications, Vol. 25, No. 6. (September 2015), pp. 1478-1492,


Theory suggests that natural fire regimes can result in landscapes that are both self-regulating and resilient to fire. For example, because fires consume fuel, they may create barriers to the spread of future fires, thereby regulating fire size. Top-down controls such as weather, however, can weaken this effect. While empirical examples demonstrating this pattern–process feedback between vegetation and fire exist, they have been geographically limited or did not consider the influence of time between fires and weather. The availability of remotely ...


Increased wind erosion from forest wildfire: implications for contaminant-related risks

Journal of Environment Quality, Vol. 35, No. 2. (2 February 2006), pp. 468-478,


Assessments of contaminant-related human and ecological risk require estimation of transport rates, but few data exist on wind-driven transport rates in nonagricultural systems, particularly in response to ecosystem disturbances such as forest wildfire and also relative to water-driven transport. The Cerro Grande wildfire in May of 2000 burned across ponderosa pine (Pinus ponderosa Douglas ex P.&C. Lawson var. scopulorum Englem.) forest within Los Alamos National Laboratory in northern New Mexico, where contaminant transport and associated post-fire inhalation risks are of concern. ...


Addition of multiple limiting resources reduces grassland diversity

Nature, Vol. 537, No. 7618. (24 August 2016), pp. 93-96,


Niche dimensionality provides a general theoretical explanation for biodiversitymore niches, defined by more limiting factors, allow for more ways that species can coexist. Because plant species compete for the same set of limiting resources, theory predicts that addition of a limiting resource eliminates potential trade-offs, reducing the number of species that can coexist. Multiple nutrient limitation of plant production is common and therefore fertilization may reduce diversity by reducing the number or dimensionality of belowground limiting factors. At the same time, ...


Grassland species loss resulting from reduced niche dimension

Nature, Vol. 446, No. 7137. (25 March 2007), pp. 791-793,


Intact ecosystems contain large numbers of competing but coexisting species. Although numerous alternative theories have provided potential explanations for this high biodiversity, there have been few field experiments testing between these theories. In particular, theory predicts that higher diversity of coexisting competitors could result from greater niche dimensionality1, for example larger numbers of limiting resources or factors. Alternatively, diversity could be independent of niche dimensionality because large numbers of species can coexist when limited by just one or two factors if ...


Size asymmetry of resource competition and the structure of plant communities

Journal of Ecology, Vol. 104, No. 4. (July 2016), pp. 899-910,


Plant communities show two general responses to gradients of soil resources: a decrease in species richness at high levels of resource availability and an associated shift in species composition from small and slow-growing species to large and fast-growing species. Models attempting to explain these responses have usually focused on a single pattern and provided contradicting predictions concerning the underlying mechanisms. [\n] We use an extension of Tilman's resource competition model to investigate the hypothesis that both patterns may ...


Size asymmetry of resource competition and the structure of plant communities: commentary on DeMalach et al 2016

Journal of Ecology, Vol. 104, No. 4. (July 2016), pp. 911-912,


[Excerpt] The hump-back relationship between diversity and productivity is one of the well-known patterns in ecology that have defied unequivocal explanation (Mittelbach et al. 2001; Šímová, Li & Storch 2013). While it has often been argued that the decline of species richness under high productivity is due to more intense competition, it has never been made fully clear why extinction under high productivity should be more likely compared to low productivity. DeMalach et al. (2016) present a simple and elegant explanation: it ...


Effects of resource additions on species richness and ANPP in an alpine meadow community

Journal of Plant Ecology, Vol. 3, No. 1. (01 March 2010), pp. 25-31,


[Aims] Theories based on resource additions indicate that plant species richness is mainly determined by the number of limiting resources. However, the individual effects of various limiting resources on species richness and aboveground net primary productivity (ANPP) are less well understood. Here, we analyzed potential linkages between additions of limiting resources, species loss and ANPP increase and further explored the underlying mechanisms. [Methods] Resources (N, P, K and water) were added in a completely randomized block design to alpine meadow plots in ...


Nutrient co-limitation of primary producer communities

Ecology Letters, Vol. 14, No. 9. (September 2011), pp. 852-862,


Synergistic interactions between multiple limiting resources are common, highlighting the importance of co-limitation as a constraint on primary production. Our concept of resource limitation has shifted over the past two decades from an earlier paradigm of single-resource limitation towards concepts of co-limitation by multiple resources, which are predicted by various theories. Herein, we summarise multiple-resource limitation responses in plant communities using a dataset of 641 studies that applied factorial addition of nitrogen (N) and phosphorus (P) in freshwater, marine and terrestrial ...


Where, why and how? Explaining the low-temperature range limits of temperate tree species

Journal of Ecology, Vol. 104, No. 4. (July 2016), pp. 1076-1088,


Attempts at explaining range limits of temperate tree species still rest on correlations with climatic data that lack a physiological justification. Here, we present a synthesis of a multidisciplinary project that offers mechanistic explanations. Employing climatology, biogeography, dendrology, population and reproduction biology, stress physiology and phenology, we combine results from in situ elevational (Swiss Alps) and latitudinal (Alps vs. Scandinavia) comparisons, from reciprocal common garden and phytotron studies for eight European broadleaf tree species. [\n] We show that ...


Indonesian fire activity and smoke pollution in 2015 show persistent nonlinear sensitivity to El Niño-induced drought

Proceedings of the National Academy of Sciences, Vol. 113, No. 33. (16 August 2016), pp. 9204-9209,


[Significance] The 2015 Indonesian fire season, in terms of fire activity and pollution, was the most severe since the NASA Earth Observing satellite system began observations in the early 2000s. Our estimates show that the 2015 CO2-equivalent biomass burning emissions for all of Indonesia were between the 2013 annual fossil fuel CO2 emissions of Japan and India. Longer-term records of airport visibility in Sumatra and Kalimantan show that 2015 ranked among the worst episodes on record. Analysis of dry season rainfall shows ...


Thermodynamic control of anvil cloud amount

Proceedings of the National Academy of Sciences, Vol. 113, No. 32. (09 August 2016), pp. 8927-8932,


[Significance] Assessing the response of clouds to global warming remains a challenge of climate science. Past research has elucidated what controls the height and temperature of high-level anvil clouds, but the factors that control their horizontal extent remained uncertain. We show that the anvil cloud amount is expected to shrink as the climate warms or when convection becomes more clustered, due to a mechanism rooted in basic energetic and thermodynamic properties of the atmosphere. It is supported by three climate models and ...


Tropical anvil clouds and climate sensitivity

Proceedings of the National Academy of Sciences, Vol. 113, No. 32. (09 August 2016), pp. 8897-8899,


[Excerpt] The surface temperature of Earth is being increased by human activities, principally by the release of greenhouse gases (1). Future warming will depend upon the rate at which greenhouse gases are released and the sensitivity of Earth’s surface temperature to those increased greenhouse gases. An often used metric of the sensitivity of Earth’s climate is the equilibrium climate sensitivity, the amount of global average surface warming that is the steady, long-term response to a doubling of carbon dioxide. The equilibrium ...


Bistability, spatial interaction, and the distribution of tropical forests and savannas

Ecosystems (2016), pp. 1-12,


Recent work has indicated that tropical forest and savanna can be alternative stable states under a range of climatic conditions. However, dynamical systems theory suggests that in case of strong spatial interactions between patches of forest and savanna, a boundary between both states is only possible at conditions in which forest and savanna are equally stable, called the ‘Maxwell point.’ Frequency distributions of MODIS tree-cover data at 250 m resolution were used to estimate such Maxwell points with respect to the ...

Cholera dynamics and El Niño-Southern Oscillation

Science, Vol. 289, No. 5485. (2000), pp. 1766-1769,


Analysis of a monthly 18-year cholera time series from Bangladesh shows that the temporal variability of cholera exhibits an interannual component at the dominant frequency of El Niño-Southern Oscillation (ENSO). Results from nonlinear time series analysis support a role for both ENSO and previous disease levels in the dynamics of cholera. Cholera patterns are linked to the previously described changes in the atmospheric circulation of south Asia and, consistent with these changes, to regional temperature anomalies. ...


Snowfall-driven growth in East Antarctic ice sheet mitigates recent sea-level rise

Science, Vol. 308, No. 5730. (2005), pp. 1898-1901,


Satellite radar altimetry measurements indicate that the East Antarctic ice-sheet interior north of 81.6°S increased in mass by 45 ± 7 billion metric tons per year from 1992 to 2003. Comparisons with contemporaneous meteorological model snowfall estimates suggest that the gain in mass was associated with increased precipitation. A gain of this magnitude is enough to slow sea-level rise by 0.12 ± 0.02 millimeters per year. ...


Streamflow and water well responses to earthquakes

Science, Vol. 300, No. 5628. (2003), pp. 2047-2049,


Earthquake-induced crustal deformation and ground shaking can alter stream flow and water levels in wells through consolidation of surficial deposits, fracturing of solid rocks, aquifer deformation, and the clearing of fracture-filling material. Although local conditions affect the type and amplitude of response, a compilation of reported observations of hydrological response to earthquakes indicates that the maximum distance to which changes in stream flow and water levels in wells have been reported is related to earthquake magnitude. Detectable streamflow changes occur in ...


Geomorphology and vegetation on hillslopes: Interactions, dependencies, and feedback loops

Geomorphology, Vol. 116, No. 3-4. (01 April 2010), pp. 206-217,


The linkages between vegetation and hillslope geomorphology have been the subject of serious study for years, but traditionally, ecologists and geomorphologists have viewed these interactions as unidirectional. On the one hand, botanists and landscape ecologists have examined the effects of hillslope features, processes, and materials on vegetation structure, composition, and dynamics. Focus has been placed on the effects of topography (elevation, slope angle, slope aspect), edaphic factors, rock type, and geomorphic disturbance (mass movement, snow avalanches, land surface erosion). On the ...


Climatic feedbacks and desertification: the Mediterranean model

Journal of Climate, Vol. 18, No. 5. (1 March 2005), pp. 684-701,


Mesometeorological information obtained in several research projects in southern Europe has been used to analyze perceived changes in the western Mediterranean summer storm regime. A procedure was developed to disaggregate daily precipitation data into three main components: frontal precipitation, summer storms, and Mediterranean cyclogenesis. Working hypotheses were derived on the likely processes involved. The results indicate that the precipitation regime in this Mediterranean region is very sensitive to variations in surface airmass temperature and moisture. Land-use perturbations that accumulated over historical ...


On underestimation of global vulnerability to tree mortality and forest die-off from hotter drought in the Anthropocene

Ecosphere, Vol. 6, No. 8. (August 2015), art129,


Patterns, mechanisms, projections, and consequences of tree mortality and associated broad-scale forest die-off due to drought accompanied by warmer temperatures—“hotter drought”, an emerging characteristic of the Anthropocene—are the focus of rapidly expanding literature. Despite recent observational, experimental, and modeling studies suggesting increased vulnerability of trees to hotter drought and associated pests and pathogens, substantial debate remains among research, management and policy-making communities regarding future tree mortality risks. We summarize key mortality-relevant findings, differentiating between those implying lesser versus greater levels of ...


Factors affecting Lymantria dispar mortality in a willow wood in northern Italy

Bulletin of Insectology, Vol. 62, No. 1. (2009), pp. 21-25


Mortality factors affecting a Lymantria dispar (L.) (Lepidoptera Lymantriidae) population in a willow wood next to the Po River (northern Italy) were studied from 1997 to 2007. In that period population density of L. dispar was low, ranging from 5.5 egg masses/100 trees to 18.8 egg masses/100 trees. Willow woods are not the most suitable habitat for gypsy moth populations, which rarely increase to an epidemic level on this host. Mortality is affected by the action of several natural enemies: Anastatus ...


Study of a collaborative repository of semantic metadata and models for regional environmental datasets' multivariate transformations

edited by Giorgio Guariso


A semantic modelling procedure is introduced to ease array-based multivariate transformations of public environmental data, along with the architecture of a collaborative repository of modelling meta-information based on the procedure. [\n] The procedure, Semantic Array Programming (SemAP), is intended as a lightweight paradigm to support integrated natural resources modelling and management (INRMM), in the context of wide-scale transdisciplinary modelling for environment (WSTMe, here tested from catchment up to regional and continental scale). [\n] It is a common experience among computational scientists, ...

[Excerpt] In this article, I give an overview of the recent contribution of Finney et al. (1) to our understanding of how wildfires spread by providing its scientific context and also by putting forward the possible impact on the field. [...] [\n] Wildfires are important to the natural sciences. Since deep time, the top surface of the Earth’s crust has been the interface where abundant plant organic matter meets an atmosphere rich in oxygen. This interface is flammable, especially in dry, windy, ...


Role of buoyant flame dynamics in wildfire spread

Proceedings of the National Academy of Sciences, Vol. 112, No. 32. (11 August 2015), pp. 9833-9838,


[Significance] Wildfires burn millions of hectares per year on every inhabited continent, but the physical mechanism governing spread is not known. Models of wildfire spread are widely used for prediction, firefighter training, and ecological research but have assumed various formulations of known heat transfer processes (radiation and convection) absent a definitive theory of their organization. New experimental evidence reported here reveals how buoyancy generated by the fire induces vorticity and instabilities in the flame zone that control the convective heating needed to ...


Isoprene emissions and climate

Atmospheric Environment, Vol. 43, No. 39. (01 December 2009), pp. 6121-6135,


Biogenic volatile organic compounds (BVOCs) play an important role in atmospheric chemistry and the carbon cycle. Isoprene is quantitatively the most important of the non-methane BVOCs (NMBVOCs), with an annual emission of about 400–600 TgC; about 90% of this is emitted by terrestrial plants. Incorporating a mechanistic treatment of isoprene emissions within land-surface schemes has recently become a focus for the modelling community, the aim being to quantify the potential magnitude of associated climate feedbacks. However, these efforts are hampered by major ...
