Introduction
My research interests lie in understanding the processes that generated the diversity of life, but also how humans erode this diversity. To answer these questions, I integrate phylogenies, maps, traits and remote sensing. I work at large-scales, taking advantage of recently developed technologies, and data assembled for thousands of species across countries and continents.

Article
Full-text available
A rich body of evidence from local-scale experiments and observational studies has revealed stabilizing effects of biodiversity on ecosystem functioning. However, whether these effects emerge across entire regions and continents remains largely overlooked. Here we combine data on the distribution of more than 57,500 plant species and remote-sensing...

Introduced pathogens can alter the geographic distribution of susceptible host species. For example, Batrachochytrium dendrobatidis (Bd) is a fungal pathogen that has been linked to the global decline and extinction of numerous amphibian species during the last four decades. A growing number of studies have described the distribution of Bd and susc...
Article
Continental mountain areas cover <15% of global land surface, yet these regions concentrate >80% of global terrestrial diversity. One prominent hypothesis to explain this pattern proposes that high mountain diversities could be explained by higher diversification rates in regions of high topographic complexity (HTC). While high speciation in mounta...
Article
Full-text available
The broadening in species’ thermal tolerance limits and breadth from tropical to temperate latitudes is proposed to reflect spatial gradients in temperature seasonality, but the importance of seasonal shifts in thermal tolerances within and across locations is much less appreciated. We performed thermal assays to examine the maximum and minimum cri...
Article
Full-text available
Regional diversity can increase owing to either the packing of species within regional niche space or the expansion of regional niche space. Yet, the primary factors dictating these dynamics remain poorly understood. Here, we assess the relative influence of current environmental conditions (net primary productivity, NPP) versus historic environmen...
Article
Full-text available
It has been argued that the loss of phylogenetic diversity (PD) from species extinctions will result in concomitant loss of functional diversity (FD). As a result, species extinction undermines not only unique evolutionary history, but also ecosystem function and stability. Using data from > 6,000 amphibian species globally, we assess the potential...
Article
Wildlife trade is a multibillion dollar industry that is driving species toward extinction. Of >31,500 terrestrial bird, mammal, amphibian, and squamate reptile species, ~18% ( N = 5579) are traded globally. Trade is strongly phylogenetically conserved, and the hotspots of this trade are concentrated in the biologically diverse tropics. Using diffe...

Many mechanisms have been hypothesized to explain Bergmanns rule - the correlation of body size with latitude. However, it is not feasible to assess the contribution of hypothesised mechanisms by experimental manipulation or statistical correlation. Here, we evaluate two of the principal hypothesised mechanisms, related to thermoregulation and reso...

1.Assemblage similarity decays with geographic distance-a pattern known as the distance-decay relationship. While this pattern has been investigated for a wide range of organisms, ecosystems, and geographical gradients, whether these changes vary more cryptically across different forest strata (from ground to canopy) remains elusive. 2.Here, we inv...
Article
Full-text available
Species distributions in terrestrial ecosystems are three‐dimensional, spanning both the horizontal landscape and the vertical space provided by the physical environment. Classical hypotheses suggest that communities become more vertically stratified with increasing species richness, owing to reduced competition or finer niche subdivision. However,...
Article
Full-text available
Whether or not species track native climatic conditions during invasions (i.e., climate match hypothesis) is fundamental to understand and prevent potential impacts of invasive species. Recent empirical work suggests that climatic mismatches between native and invasive ranges are pervasive. Whether these differences are due to adaptation to new cli...
Article
Full-text available
Current ecological and evolutionary research are increasingly moving from species- to trait-based approaches because traits provide a stronger link to organism’s function and fitness. Trait databases covering a large number of species are becoming available, but such data remains scarce for certain groups. Amphibians are among the most diverse vert...
Article
Full-text available
There is an increasing interest in measuring loss of phylogenetic diversity and evolutionary distinctiveness which together depict the evolutionary history of conservation interest. Those losses are assessed through the evolutionary relationships between species and species threat status or extinction probabilities. Yet, available information is no...
Article
Full-text available
Aim: Whether the gradients of global diversity conform to equilibrium or non-equilibrium dynamics remains an unresolved question in ecology and evolution. Here, we evaluate four prominent hypotheses which invoke either equilibrium (more individuals, niche diversity) or non-equilibrium dynamics (diversification rate, evolutionary time) to explain sp...

Question
Hello,
I am looking for studies that investigated temporal changes in thermal traits (e.g., CTmin and CTmax) in response to temperature variation over seasons. For instance, does CTmin and CTmax follow temperature variation over seasons? I assumed this would be a simple question, but I found just a few studies that tackled this directly, mostly dating from the '70s and '80s. Most "newer" studies focused on laboratory experiments, which is not quite the same. I would appreciate your help.
