Predicting conifer establishment post wildfire in mixed conifer forests of the North American Mediterranean-climate zone

  
Ecosphere, Vol. 7, No. 12. (December 2016), e01609, https://doi.org/10.1002/ecs2.1609

Abstract

Due to fire suppression policies, timber harvest, and other management practices over the last century, many low‐ to mid‐elevation forests in semiarid parts of the western United States have accumulated high fuel loads and dense, multi‐layered canopies that are dominated by shade‐tolerant and fire‐sensitive conifers. To a great extent, the future status of western US forests will depend on tree species’ responses to patterns and trends in fire activity and fire behavior and postfire management decisions. This is especially the case ...

 

Positive biodiversity-productivity relationships in forests: climate matters

  
Biology Letters, Vol. 14, No. 4. (04 April 2018), 20170747, https://doi.org/10.1098/rsbl.2017.0747

Abstract

While it is widely acknowledged that forest biodiversity contributes to climate change mitigation through improved carbon sequestration, conversely how climate affects tree species diversity–forest productivity relationships is still poorly understood. We combined the results of long-term experiments where forest mixtures and corresponding monocultures were compared on the same site to estimate the yield of mixed-species stands at a global scale, and its response to climatic factors. We found positive mixture effects on productivity using a meta-analysis of 126 case studies established ...

Temperature accelerates the rate fields become forests

  
Proceedings of the National Academy of Sciences (16 April 2018), 201716665, https://doi.org/10.1073/pnas.1716665115

Abstract

[Significance] The transition of abandoned fields into forests (secondary succession) has long informed ecologists’ understanding of community assembly and species interactions. Intriguingly, rates of secondary succession show a striking latitudinal pattern, with dominance by woody species (>50% cover) taking less than a decade in the southern United States, and up to 60 years in New England. We used a large-scale experimental network to test how multiple drivers (climate, soils, and the identity of dominant species) influence field-to-forest transitions. We found consistent evidence ...

 

Portugal wildfire management in a new era assessing fire risks, resources and reforms

  
(February 2018)

Abstract

[Executive summary] Portugal has one of the highest forest fire risk rankings in Europe. Fire researchers all point to the same combination of contributing factors: shifting demographics with population moving from rural to urban areas, changes in land use with more agricultural and forested areas left unattended and not being maintained, and fragmentation of land ownership patterns that discourage investment in forest management and fire planning. The trend of annual burned area for the last four decades confirms a new level in fire activity in Portugal, despite ...

Assessment and validation of wildfire susceptibility and hazard in Portugal

  
Natural Hazards and Earth System Science, Vol. 10, No. 3. (16 March 2010), pp. 485-497, https://doi.org/10.5194/nhess-10-485-2010

Abstract

A comprehensive methodology to assess forest fire susceptibility, that uses variables of strong spatial correlation, is presented and applied for the Portuguese mainland. Our study is based on a thirty-year chronological series of burnt areas. The first twenty years (1975–1994) are used for statistical modelling, and the last ten (1995–2004) are used for the independent validation of results. The wildfire affected areas are crossed with a set of independent layers that are assumed to be relevant wildfire conditioning factors: elevation, slope, ...

 

Global MODIS fraction of green vegetation cover for monitoring abrupt and gradual vegetation changes

  
Remote Sensing, Vol. 10, No. 4. (23 April 2018), 653, https://doi.org/10.3390/rs10040653

Abstract

The presence and distribution of green vegetation cover in the biosphere are of paramount importance in investigating cause-effect phenomena at the land/atmosphere interface, estimating primary production rates as part of global carbon and water cycle assessments and evaluating soil protection and land use change over time. The fraction of green vegetation cover (FCover) as estimated from satellite observations has already been demonstrated to be an extraordinarily useful product for understanding vegetation cover changes, for supporting ecosystem service assessments over areas with ...

 

Long-term changes of the wildland–urban interface in the Polish Carpathians

  
ISPRS International Journal of Geo-Information, Vol. 7, No. 4. (01 April 2018), 137, https://doi.org/10.3390/ijgi7040137

Abstract

The Wildland–Urban Interface (WUI) is the area where houses and wildland vegetation meet or intermingle, which causes many environmental problems. The current WUI is widespread in many regions, but it is unclear how the WUI evolved, especially in regions where both houses and forest cover have increased. Here we compared WUI change in the Polish Carpathians for 1860 and 2013 in two study areas with different land use history. Our western study area experienced gradual forest increase and housing growth over ...

 

Climate-vegetation-fire interactions and feedbacks: trivial detail or major barrier to projecting the future of the Earth system?

  
Wiley Interdisciplinary Reviews: Climate Change, Vol. 7, No. 6. (1 November 2016), pp. 910-931, https://doi.org/10.1002/wcc.428

Abstract

Fire is a complex process involving interactions and feedbacks between biological, socioeconomic, and physical drivers across multiple spatial and temporal scales. This complexity limits our ability to incorporate fire into Earth system models and project future fire activity under climate change. Conceptual, empirical, and process models have identified the mechanisms and processes driving fire regimes, and provide a useful basis to consider future fire activity. However, these models generally deal with only one component of fire regimes, fire frequency, and do ...

 

Predicting climate change effects on wildfires requires linking processes across scales

  
Wiley Interdisciplinary Reviews: Climate Change, Vol. 2, No. 1. (January 2011), pp. 99-112, https://doi.org/10.1002/wcc.92

Abstract

Accurate process‐based prediction of climate change effects on wildfires requires coupling processes across orders of magnitude of time and space scales, because climate dynamic processes operate at relatively large scales (e.g., hemispherical and centennial), but fire behavior processes operate at relatively small scales (e.g., molecules and microseconds). In this review, we outline some of the current understanding of the processes by which climate/meteorology controls wildfire behavior by focusing on four critical stages of wildfire development: (1) fuel drying, (2) ignition, (3) ...

 

A data-driven approach to assess large fire size generation in Greece

  
Natural Hazards, Vol. 88, No. 3. (2017), pp. 1591-1607, https://doi.org/10.1007/s11069-017-2934-z

Abstract

Identifying factors and drivers which control large fire size generation is critical for planning fire management activities. This study attempts to determine the role of fire suppression tactics and behavior, weather, topography and landscape features on two different datasets of large fire size (500–1000 ha) and very large fire size (>1000 ha) compared to two datasets of small fire size (<50 ha) which occurred in Greece, during the period 1984–2009. In this context, we used a logistic regression (LR) analysis and ...

 

How wildfire risk is related to urban planning and Fire Weather Index in SE France (1990–2013)

  
Science of The Total Environment, Vol. 621 (April 2018), pp. 120-129, https://doi.org/10.1016/j.scitotenv.2017.11.174

Abstract

[Highlights] [::] Land use planning in SE France led to increased housing density in 1990-2012 and maintained WUI wildfire risk constant. [::] The number of buildings increased by 30% but WUI area increased by less than 5% as housing density increased. [::] Fire frequency and burned area increase substantially as Fire Weather Index surpasses a threshold value of 90. [Abstract] Wildfires burn > 450,000 ha of forest every year in Euro-Mediterranean countries. Many fires originate in the Wildland Urban Interface (WUI) where housing density and weather ...

 

Mapping regional patterns of large forest fires in Wildland–Urban Interface areas in Europe

  
Journal of Environmental Management, Vol. 172 (May 2016), pp. 112-126, https://doi.org/10.1016/j.jenvman.2016.02.013

Abstract

[Highlights] [::] A European Wildland–Urban Interface (WUI) map was presented. [::] The European WUI areas have been correlated with occurrence of large burned surfaces. [::] Peri-urban areas and Mediterranean touristic areas show strong co-occurrence of WUI and fires. [::] Burned surface probabilities within 5000 m of the WUI areas are estimated to map fire risk. [Abstract] Over recent decades, Land Use and Cover Change (LUCC) trends in many regions of Europe have reconfigured the landscape structures around many urban areas. In these areas, the proximity to landscape ...

 

Land use strategies to mitigate climate change in carbon dense temperate forests

  
Proceedings of the National Academy of Sciences, Vol. 115, No. 14. (03 April 2018), pp. 3663-3668, https://doi.org/10.1073/pnas.1720064115

Abstract

[Significance] Regional quantification of feasibility and effectiveness of forest strategies to mitigate climate change should integrate observations and mechanistic ecosystem process models with future climate, CO2, disturbances from fire, and management. Here, we demonstrate this approach in a high biomass region, and found that reforestation, afforestation, lengthened harvest cycles on private lands, and restricting harvest on public lands increased net ecosystem carbon balance by 56% by 2100, with the latter two actions contributing the most. Forest sector emissions tracked with our life ...

Abstract

Climate change could increase fire risk across most of the managed boreal forest. Decreasing this risk by increasing the proportion of broad-leaved tree species is an overlooked mitigation–adaption strategy with multiple benefits. ...

 

Fire forbids fifty-fifty forest

  
PLOS ONE, Vol. 13, No. 1. (19 January 2018), e0191027, https://doi.org/10.1371/journal.pone.0191027

Abstract

Recent studies have interpreted patterns of remotely sensed tree cover as evidence that forest with intermediate tree cover might be unstable in the tropics, as it will tip into either a closed forest or a more open savanna state. Here we show that across all continents the frequency of wildfires rises sharply as tree cover falls below ~40%. Using a simple empirical model, we hypothesize that the steepness of this pattern causes intermediate tree cover (30‒60%) to be unstable for a ...

 

New global forest/non-forest maps from ALOS PALSAR data (2007–2010)

  
Remote Sensing of Environment, Vol. 155 (December 2014), pp. 13-31, https://doi.org/10.1016/j.rse.2014.04.014

Abstract

[Highlights] [::] Global mosaics of ALOS-SAR data were generated annually from 2007 to 2010. [::] Region variability in L-band HH and HV gamma-naught (γ0) for forests was observed. [::] Region-specific thresholds were applied to produce a global forest/non-forest map. [::] The overall agreement was 95%. [::] Annual decreases of HH and HV γ0 suggest a decrease in forest and smoothing Earth. [Abstract] Four global mosaics of Advanced Land Observing Satellite (ALOS) Phased Arrayed L-band Synthetic Aperture Radar (SAR) HH and HV polarization data were generated at 25 m ...

 

Rethinking wildfires and forest watersheds

  
Science, Vol. 359, No. 6379. (01 March 2018), pp. 1001.2-1002, https://doi.org/10.1126/science.aar8120

Abstract

[Excerpt] [...] The secondary threats of wildfires to water supply are particularly concerning, as almost two-thirds of municipalities in North America receive their drinking water from forested areas [...]. Key threats include increased potential for erosion, landslides, debris flows, floods, and introduction of contaminants to streams, with potentially catastrophic implications for community infrastructure, drinking water treatment, public health, and aquatic ecosystem health [...]. [\n] Given the rising threats and costs associated with the current wildfire trend, we must change the way we manage ...

Pine Wilt Disease: a threat to European forestry

  
European Journal of Plant Pathology In European Journal of Plant Pathology, Vol. 133, No. 1. (24 December 2012), pp. 89-99, https://doi.org/10.1007/s10658-011-9924-x

Abstract

Bursaphelenchus xylophilus , the pinewood nematode (PWN) and causal agent of Pine Wilt Disease (PWD), was detected for the first time, in 1999, in Portugal, and in Europe. Despite the efforts of the Portuguese National Forestry and Quarantine Authorities, the disease has spread to new forest areas in the centre of mainland Portugal, in 2008, and to the island of Madeira, in 2009. More recently, two foci of PWD were reported from Spain. The free circulation of non-treated wood and wood ...

 

Spatially-explicit models of global tree density

  
Scientific Data, Vol. 3 (16 August 2016), 160069, https://doi.org/10.1038/sdata.2016.69

Abstract

Remote sensing and geographic analysis of woody vegetation provide means of evaluating the distribution of natural resources, patterns of biodiversity and ecosystem structure, and socio-economic drivers of resource utilization. While these methods bring geographic datasets with global coverage into our day-to-day analytic spheres, many of the studies that rely on these strategies do not capitalize on the extensive collection of existing field data. We present the methods and maps associated with the first spatially-explicit models of global tree density, which relied ...

 

Adapt to more wildfire in western North American forests as climate changes

  
Proceedings of the National Academy of Sciences, Vol. 114, No. 18. (02 May 2017), pp. 4582-4590, https://doi.org/10.1073/pnas.1617464114

Abstract

Wildfires across western North America have increased in number and size over the past three decades, and this trend will continue in response to further warming. As a consequence, the wildland–urban interface is projected to experience substantially higher risk of climate-driven fires in the coming decades. Although many plants, animals, and ecosystem services benefit from fire, it is unknown how ecosystems will respond to increased burning and warming. Policy and management have focused primarily on specified resilience approaches aimed at resistance ...

 

The interaction of fire, fuels, and climate across Rocky Mountain forests

  
BioScience, Vol. 54, No. 7. (2004), pp. 661-676, https://doi.org/10.1641/0006-3568(2004)054[0661:tioffa]2.0.co;2

Abstract

Understanding the relative influence of fuels and climate on wildfires across the Rocky Mountains is necessary to predict how fires may respond to a changing climate and to define effective fuel management approaches to controlling wildfire in this increasingly populated region. The idea that decades of fire suppression have promoted unnatural fuel accumulation and subsequent unprecedentedly large, severe wildfires across western forests has been developed primarily from studies of dry ponderosa pine forests. However, this model is being applied uncritically across ...

 

Fire-induced deforestation in drought-prone Mediterranean forests: drivers and unknowns from leaves to communities

  
Ecological Monographs (22 January 2018), https://doi.org/10.1002/ecm.1285

Abstract

Over the past 15 years, 3 million hectares of forests have been converted into shrublands or grasslands in the Mediterranean countries of the European Union. Fire and drought are the main drivers underlying this deforestation. Here we present a conceptual framework for the process of fire-induced deforestation based on the interactive effects of fire and drought across three hierarchical scales: resistance in individuals, resilience in populations, and transitions to a new state. At the individual plant level, we review the traits ...

 

Biodiversity and ecosystem services in forest ecosystems: a research agenda for applied forest ecology

  
Journal of Applied Ecology, Vol. 54, No. 1. (1 February 2017), pp. 12-27, https://doi.org/10.1111/1365-2664.12669

Abstract

Given the substantial contributions of forest biodiversity and ecosystem services to society, forest sciences have a large potential to contribute to the integrity and sustainability of our future. This is especially true when the roles of biodiversity for sustaining ecosystem services are considered. [\n] The rapid expansion of sustainable forest management (SFM) has resulted in the adoption of various forest management frameworks intended to safeguard biodiversity. Concurrently, the importance of forest ecosystem services has been increasingly recognized. Although some initiatives aimed ...

 

Wildfires

  
In Present and future probability of meteorological and hydrological hazards in Europe (2016), pp. 112-118

Abstract

[Excerpt: Introduction] Uncontrolled forest fires impact both natural and built-up environments as well as humans. The occurrence of a forest fire requires the same basic elements as any fire: heat, oxygen and fuel. Preceding and prevailing weather conditions are crucial for setting conditions susceptible to fire in a forest. Drought, high temperatures and pronounced evaporation dry off organic material in forests, i.e. the fuel. Strong wind during/after ignition substantially intensifies spreading of the fire and raises the likelihood of the surface ...

Abstract

Forests cover over a third of the total land area of Europe. In recent years, large forest fires have repeatedly affected Europe, in particular the Mediterranean countries. Fire danger is influenced by weather in the short term, and by climate when considering longer time intervals. In this work, the emphasis is on the direct influence on fire danger of weather and climate. [\n] For climate analysis at the continental scale, a daily high-emission scenario (RCP 8.5) was considered up to the end ...

Unravelling the response of diurnal raptors to land use change in a highly dynamic landscape in northwestern Spain: an approach based on satellite earth observation data

  
European Journal of Wildlife Research, Vol. 63, No. 2. (2017), pp. 1-15, https://doi.org/10.1007/s10344-017-1097-2

Abstract

Land use and land cover change (LULCC) is one of the main components of current anthropogenic global change. Unravelling the ecological response of biodiversity to the combined effect of land use change and other stressors is essential for effective conservation. For this purpose, we used co-inertia analysis to combine LULCC analysis of earth observation satellite data-derived maps and raptor data obtained from road censuses conducted in 2001 and 2014 at sampling unit level (10 km2 spatial resolution), in northwestern Spain (province ...

 

Intentional fire-spreading by “firehawk” raptors in Northern Australia

Empirical models of annual post-fire erosion on mulched and unmulched hillslopes

  
CATENA, Vol. 163 (April 2018), pp. 276-287, https://doi.org/10.1016/j.catena.2017.12.029

Abstract

[Highlights] [::] Measured hillslope erosion with and without mulch following the 2012 High Park Fire. [::] Mulched slopes had fourfold lower erosion rates during the first year after fire. [::] Bare soil was the strongest control on erosion rates. [::] Empirical models predict erosion using bare soil, precipitation, and flow length. [::] Empirical model performance ranged from poor to good for different fires. [Abstract] Erosion is one of the primary land management concerns following wildfire. This study examines controls on post-fire hillslope-scale erosion for the 2012 High Park ...

 

Evidence for declining forest resilience to wildfires under climate change

  
Ecology Letters (12 December 2017), https://doi.org/10.1111/ele.12889

Abstract

Forest resilience to climate change is a global concern given the potential effects of increased disturbance activity, warming temperatures and increased moisture stress on plants. We used a multi-regional dataset of 1485 sites across 52 wildfires from the US Rocky Mountains to ask if and how changing climate over the last several decades impacted post-fire tree regeneration, a key indicator of forest resilience. Results highlight significant decreases in tree regeneration in the 21st century. Annual moisture deficits were significantly greater from ...

 

Tamm Review - Shifting global fire regimes: lessons from reburns and research needs

  
Forest Ecology and Management, Vol. 396 (July 2017), pp. 217-233, https://doi.org/10.1016/j.foreco.2017.03.035

Abstract

[Highlights] [::] We reviewed published studies on reburns in fire-adapted ecosystems of the world. [::] Fire regimes often have shifted from frequent to infrequent fire return intervals. [::] Legacies of past burns constrain the spread and severity of future fires. [::] Periodic fire generally favors fire-adapted vegetation and limits closed forests. [::] Better understanding of reburns informs climate change adaptation methods. [Abstract] Across the globe, rising temperatures and altered precipitation patterns have caused persistent regional droughts, lengthened fire seasons, and increased the number of weather-driven extreme fire events. ...

Most models project warmer and drier climates that will contribute to larger and more frequent wildfires. However, it remains unknown how repeated wildfires alter post-fire successional patterns and forest structure. Here, we test the hypothesis that the number of wildfires, as well as the order and severity of wildfire events interact to alter forest structure and vegetation recovery and implications for vegetation management. In 2014, we examined forest structure, composition, and tree regeneration in stands that burned 1–18 yr before a ...

 

An assessment of forest biomass maps in Europe using harmonized national statistics and inventory plots

  
Forest Ecology and Management, Vol. 409 (February 2018), pp. 489-498, https://doi.org/10.1016/j.foreco.2017.11.047

Abstract

[Highlights] [::] We assessed four biomass maps for Europe using harmonized biomass reference data. [::] The harmonized statistics were derived from ∼430,000 plots from 26 countries. [::] All maps overestimated at low biomass and underestimated at high biomass. [::] All maps had an overall negative bias (23–43 Mg ha−1 at national level). [::] The maps relative errors was 29–40% at national level and 63–72% at cell level. [Abstract] Maps of aboveground forest biomass based on different input data and modelling approaches have been recently produced for Europe, opening up the ...

 

US natural resources and climate change: concepts and approaches for management adaptation

  
Environmental Management, Vol. 44, No. 6. (2009), pp. 1001-1021, https://doi.org/10.1007/s00267-009-9345-1

Abstract

Public lands and waters in the United States traditionally have been managed using frameworks and objectives that were established under an implicit assumption of stable climatic conditions. However, projected climatic changes render this assumption invalid. Here, we summarize general principles for management adaptations that have emerged from a major literature review. These general principles cover many topics including: (1) how to assess climate impacts to ecosystem processes that are key to management goals; (2) using management practices to support ecosystem resilience; ...

 

Stay or go - How topographic complexity influences alpine plant population and community responses to climate change

  
Perspectives in Plant Ecology, Evolution and Systematics (November 2017), https://doi.org/10.1016/j.ppees.2017.09.008

Abstract

In the face of climate change, populations have two survival options − they can remain in situ and tolerate the new climatic conditions (“stay”), or they can move to track their climatic niches (“go”). For sessile and small-stature organisms like alpine plants, staying requires broad climatic tolerances, realized niche shifts due to changing biotic interactions, acclimation through plasticity, or rapid genetic adaptation. Going, in contrast, requires good dispersal and colonization capacities. Neither the magnitude of climate change experienced locally nor the ...

 

Spreading like wildfire

  
Nature Climate Change, Vol. 7, No. 11. (November 2017), pp. 755-755, https://doi.org/10.1038/nclimate3432

Abstract

The 2017 wildfire season has seen unusually high fire levels in many parts of the world, with extensive and severe fires occurring in Chile, the Mediterranean, Russia, the US, Canada and even Greenland. Is this a sign of things to come? [Excerpt] During January and February, Chile experienced what their president Michelle Bachelet called “The greatest forest disaster in our history”. The nation was not adequately equipped to tackle these fires, leading the government to enact a state of emergency and accept ...

Abstract

This article presents, for the first time, an overview of all known tree species by scientific name and country level distribution, and describes an online database GlobalTreeSearch that provides access to this information. Based on our comprehensive analysis of published data sources and expert input, the number of tree species currently known to science is 60,065, representing 20% of all angiosperm and gymnosperm plant species. Nearly half of all tree species (45%) are found in just 10 families, with the 3 ...

 

Effects of phosphite in Pinus radiata - Fusarium circinatum interaction

  
(2016)

Abstract

The pitch canker, caused by the fungus Fusarium circinatum, is a disease under quarantine measures affecting Pinus spp. and Pseudotsuga menziesii worldwide. Characterized by the formation of large resinous cankers that girdle shoots, branches, and trunks, leads to the death of the host. To date, there are no means for the control of the pitch canker and, with the growing need to reduce the use of fungicides, another approaches must be studied. A method for the control of phytopathogenic diseases is ...

The Spanish National Forest Inventory: history, development, challenges and perspectives

  
Pesquisa Florestal Brasileira, Vol. 37, No. 91. (29 September 2017), 361, https://doi.org/10.4336/2017.pfb.37.91.1337

Abstract

It is important to have a statistically robust forest information data base which can be updated and can provide long-term information. National Forest Inventories (NFI) provide one of the best large-scale sources of information, and therefore are a cornerstone of forest policies. The scopes of NFIs, which are the primary source of data for national and large-area assessments, has been broadened to include new variables to meet increasing information requirements. This paper describes the history, methodology and guidance of Spanish NFI and international requirements. The current objectives are ...

 

Bridging national and reference definitions for harmonizing forest statistics

  
Forest Science (June 2012), pp. 214-223, https://doi.org/10.5849/forsci.10-067

Abstract

Harmonization is the process of making information and estimates comparable across administrative borders. The degree to which harmonization succeeds depends on many factors, including the conciseness of the definitions, the availability and quality of data, and the methods used to convert an estimate according to a local definition to an estimate according to the reference definition. Harmonization requires the availability and use of common reference definitions and methods for converting from estimates based on national definitions to estimates based on reference ...

 

Comparison of methods used in European National Forest Inventories for the estimation of volume increment: towards harmonisation

  
Annals of Forest Science, Vol. 73, No. 4. (2016), pp. 807-821, https://doi.org/10.1007/s13595-016-0554-5

Abstract

[Key message] The increment estimation methods of European NFIs were explored by means of 12 essential NFI features. The results indicate various differences among NFIs within the commonly acknowledged methodological frame. The perspectives for harmonisation at the European level are promising. [Context] The estimation of increment is implemented differently in European National Forest Inventories (NFIs) due to different historical origins of NFIs and sampling designs and field assessments accommodated to country-specific conditions. The aspired harmonisation of increment estimation requires a comparison and an analysis ...

 

Early postfire vegetation recovery of Pinus brutia forests: effects offire severity, prefire stand age, and aspect

  
Turkish Journal of Agriculture and Forestry, Vol. 40 (2016), pp. 723-736, https://doi.org/10.3906/tar-1601-21

Abstract

Forests dominated by serotinous tree species are usually generalized to follow an autosuccessional model of postfire recovery. However, recent studies have suggested that prefire conditions, topography, and idiosyncrasies of the fire disturbance can have notable effects on how such forests respond to fire. We investigated the effects of fire severity, prefire stand age, and aspect (slope orientation) on the early postfire recovery of Pinus brutia forest. The study site was the area of 2008 Serik-Tasağıl Fire, one of the largest forest ...

 

Upscaling species richness and abundances in tropical forests

  
Science Advances, Vol. 3, No. 10. (18 October 2017), e1701438, https://doi.org/10.1126/sciadv.1701438

Abstract

The quantification of tropical tree biodiversity worldwide remains an open and challenging problem. More than two-fifths of the number of worldwide trees can be found either in tropical or in subtropical forests, but only ≈0.000067% of species identities are known. We introduce an analytical framework that provides robust and accurate estimates of species richness and abundances in biodiversity-rich ecosystems, as confirmed by tests performed on both in silico–generated and real forests. Our analysis shows that the approach outperforms other methods. In ...

 

Daily synoptic conditions associated with large fire occurrence in Mediterranean France: evidence for a wind-driven fire regime

  
International Journal of Climatology, Vol. 37, No. 1. (January 2017), pp. 524-533, https://doi.org/10.1002/joc.4680

Abstract

Changes in wildfire activity in the Mediterranean area over recent decades increase the need for a better understanding of the fire–weather relationships and for the development of reliable models to improve fire danger prediction. This study analyses daily synoptic and local weather conditions associated with the occurrence of summer large fires (LFs) in Mediterranean France during recent decades (1973–2013). The links between large fire occurrence and synoptic conditions are analysed with composites of sea level pressure and winds at 925 hPa ...
