How disturbance, competition and dispersal interact to prevent tree range boundaries from keeping pace with climate change

Global Change Biology (28 July 2017),


Climate change is expected to cause geographic shifts in tree species’ ranges, but such shifts may not keep pace with climate changes because seed dispersal distances are often limited and competition-induced changes in community composition can be relatively slow. Disturbances may speed changes in community composition, but the interactions among climate change, disturbance and competitive interactions to produce range shifts are poorly understood. We used a physiologically-based mechanistic landscape model to study these interactions in the northeastern United States. We designed ...


Nitrogen-fixing trees inhibit growth of regenerating Costa Rican rainforests

Proceedings of the National Academy of Sciences, Vol. 114, No. 33. (15 August 2017), pp. 8817-8822,


[Significance] Regrowing tropical forests are critical for global biodiversity conservation and carbon capture. Nitrogen availability often controls how fast these forests can regrow. Because nitrogen-fixing plants are the primary source of new nitrogen into these forests, one might expect that more nitrogen fixers lead to faster forest regrowth. However, here we show that nitrogen fixers actually slow forest regrowth. Their competitive influence on neighboring trees outweighs any growth enhancement from their nitrogen inputs at this site. Our results call for a more ...


Oak decline as illustrated through plant–climate interactions near the northern edge of species range

The Botanical Review, Vol. 82, No. 1. (2016), pp. 1-23,


This paper investigates historical growth and climate records among the oak sites representing the northern edge of species range in northernmost Europe (Finland). This is to characterize plant–climate interactions for a multitude of sites where oak decline has recently been observed and understand this most recent decline in the context of the past decline studies elsewhere. Further, our paper demonstrates the procedures the tree-ring data can be used in isolating those factors significantly contributing to decline. Our findings point towards complex ...


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. ...


Multitrait successional forest dynamics enable diverse competitive coexistence

Proceedings of the National Academy of Sciences, Vol. 114, No. 13. (28 March 2017), pp. E2719-E2728,


[Significance] Walking through any forest, one is struck by the variety of plant forms coexisting. Given that all plants compete for the same basic resources, why is there not a single winner? Our study shows that when key ingredients common to all forests are accounted for—including disturbance events, competition for light, and two widely observed trait-based tradeoffs—models of niche differentiation predict forests of considerably greater diversity than was previously thought possible. In particular, our model accurately predicts the proliferation of species occupying ...


The importance of phenology for the evaluation of impact of climate change on growth of boreal, temperate and Mediterranean forests ecosystems: an overview

International Journal of Biometeorology, Vol. 44, No. 2. (2000), pp. 67-75,


An overview is presented of the phenological models relevant for boreal coniferous, temperate-zone deciduous and Mediterranean coniferous forest ecosystems. The phenology of the boreal forests is mainly driven by temperature, affecting the timing of the start of the growing season and thereby its duration, and the level of frost hardiness and thereby the reduction of foliage area and photosynthetic capacity by severe frost events. The phenology of temperate-zone forests is also mainly driven by temperature. Since temperate-zone forests are mostly mixed-species ...


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 ...


Seven shortfalls that beset large-scale knowledge of biodiversity

Annual Review of Ecology, Evolution, and Systematics, Vol. 46, No. 1. (2015), pp. 523-549,


Ecologists and evolutionary biologists are increasingly using big-data approaches to tackle questions at large spatial, taxonomic, and temporal scales. However, despite recent efforts to gather two centuries of biodiversity inventories into comprehensive databases, many crucial research questions remain unanswered. Here, we update the concept of knowledge shortfalls and review the tradeoffs between generality and uncertainty. We present seven key shortfalls of current biodiversity data. Four previously proposed shortfalls pinpoint knowledge gaps for species taxonomy (Linnean), distribution (Wallacean), abundance (Prestonian), and evolutionary ...

Plant functional traits have globally consistent effects on competition

Nature, Vol. 529, No. 7585. (14 January 2016), pp. 204-207,


[Headlines] Data from millions of trees in thousands of locations are used to show that certain key traits affect competitive ability in predictable ways, and that there are trade-offs between traits that favour growth with and without competition. [Abstract] Phenotypic traits and their associated trade-offs have been shown to have globally consistent effects on individual plant physiological functions, but how these effects scale up to influence competition, a key driver of community assembly in terrestrial vegetation, has remained unclear. Here we use growth data ...


Patterns of woody plant invasion in an Argentinean coastal grassland

Acta Oecologica, Vol. 54 (January 2014), pp. 65-71,


Coastal dune grasslands are fragile ecosystems that have historically been subjected to various types of uses and human activities. In Buenos Aires Province (Argentina), these areas are frequently afforested for urban and touristic development. The introduction and subsequent spread of exotic tree species is one of the main threats to conservation of natural grasslands as invasive trees strongly transform their structure and composition. The aim of this study was to identify patterns of woody plant invasion comparing plant communities and environmental ...


Constraints and trade-offs in Mediterranean plant communities: The case of holm oak-Aleppo pine forests

The Botanical Review, Vol. 66, No. 1. (2000), pp. 119-149,


In this paper we review those aspects that are relevant to the development of a mechanistic ecological theory to account for the structure and dynamics of Mediterranean forests, focusing our attention on mixed forests of holm oak (Quercus ilex L.), a shade-tolerant, slowgrowing species that resprouts vigorously after disturbance, and Aleppo pine (Pinus halepensis M.), a fast-growing, nonresprouting, shade-intolerant species. The main objectives of this report are: to introduce some of the primary features of these forests, showing their structural complexity ...


Spatial structure along an altitudinal gradient in the Italian central Alps suggests competition and facilitation among coniferous species

Journal of Vegetation Science, Vol. 19, No. 3. (June 2008), pp. 425-436,


Questions: What is the structure of the anthropogenic upper forest-grassland ecotone and are there differences in the spatial relationships between the tree species involved? Location: Valfurva Valley, Italian central Alps. Methods: We conducted a spatial distribution and structure analysis in three 1-ha permanent plots along an altitudinal gradient, from the treeline to the sub-alpine forest. We reconstructed the age structure from cores from each individual with diameter > 4 cm at 50 cm height. Results: All tree species and age classes ...


Higher levels of multiple ecosystem services are found in forests with more tree species

Nature Communications, Vol. 4 (8 January 2013), 1340,


Forests are of major importance to human society, contributing several crucial ecosystem services. Biodiversity is suggested to positively influence multiple services but evidence from natural systems at scales relevant to management is scarce. Here, across a scale of 400,000 km(2), we report that tree species richness in production forests shows positive to positively hump-shaped relationships with multiple ecosystem services. These include production of tree biomass, soil carbon storage, berry production and game production potential. For example, biomass production was approximately 50% greater ...


Effects of growing roots of Norway spruce (Picea abies [L.] Karst.) and European beech (Fagus sylvatica L.) on rhizosphere soil solution chemistry

Z. Pflanzenernähr. Bodenk., Vol. 164, No. 1. (2001), pp. 35-41,<35::aid-jpln35>;2-m


The chemical conditions of the rhizosphere can be very different from that of bulk soil. Up to now, little attention has been given to the problem of spatial heterogeneity and temporal dynamics of rhizosphere soil solution and little is known about the influence of different tree species on rhizosphere chemistry. In the present study, we used micro suction cups to collect soil solution from the rhizosphere of Norway spruce (Picea abies [L.] Karst.) and European beech (Fagus sylvatica L.) seedlings in ...
