Inverse sky islands: lowland river valleys drive microbial divergence while high elevations select for convergence in massive mountain ecosystems

Ecography, EarlyView.
Mountain ecosystems are often interpreted through the lens of the ‘sky island' model, where high‐elevation habitats function as isolated archipelagos. However, this model's applicability to massive, topographically complex mountain ranges where highlands are continuous and lowlands are fragmented remains untested.

The origin and nature of macroecological patterns in amphibians: old questions, novel approaches

Frontiers of Biogeography, 2013
The role of physiological parameters as determinants of macroscale patterns is still widely disputed. Using amphibians as a model, I revisited three fundamental themes in macroecology from a physiological perspective: the global diversity gradient ...

The neglected importance of managing biological invasions for sustainable development

People and Nature
Biological invasions have substantial and rising social‐ecological impacts threatening human livelihoods and communities and hampering progress towards a just and equitable world. Currently, biological invasions are not adequately recognised and included

N‐SDM 2.0: a reengineered software with extended features for nested species distribution modelling

Ecography, EarlyView.
Species distribution models (SDMs) are central tools for predicting and forecasting how species respond to environmental changes, yet their reliability depends on accurately capturing ecological processes across spatial scales while accounting for uneven data availability and resolution.

Incorporating sampling bias into ENM/SDM permutation tests: new methods and a case study on neotropical ants

Ecography, EarlyView.
Spatial sampling bias in occurrence data can generate spurious environmental associations in models of species distributions and ecological niches, and can also undermine inferences based on permutation tests made using these models. Geographic randomization tests are often used to generate distributions of expected behavior under the null hypothesis ...

Faster growing and more functionally diverse: global change alters functional trait composition of mountain plant communities in the European Alps

Ecography, EarlyView.
Understanding how global change reshapes mountain plant communities is essential for predicting biodiversity and ecosystem function in a warming world. Using resurvey data from over 1400 non‐forest vegetation plots across the European Alps, we show that community‐weighted means of key functional traits capturing important dimensions of plant ecological

‘biomod2' – extending presence–absence species distribution models to multiple data types

Ecography, EarlyView.
The R package ‘biomod2' is one of the most widely used and versatile tools for species distribution modelling (SDM), enabling ecologists to calibrate, evaluate, and project species–environment relationships across space and time using multiple modelling algorithms and ensemble forecasting.

Method in macroecology

Basic and Applied Ecology, 2004
Summary Macroecology is concerned with understanding the abundance and distribution of species at large spatial and temporal scales. Understanding pattern and process in macroecology thus presents a considerable methodological challenge, as the scales of interest are simply too large for the traditional ecological approach of experimental ...

Scrutinizing the Wallacean shortfall: global gaps in snake occurrence data across space and environment

Ecography, EarlyView.
Occurrence records are fundamental for ecological and evolutionary research, providing key information on species' geographic ranges. However, these records are often taxonomically, spatially, and temporally biased, requiring caution in their use. Here, we analysed the spatial coverage of occurrence records for over 3500 snake species worldwide to ...

High‐latitude night shortening forces birds to accept increasingly diurnal migration to maintain flight duration

Journal of Avian Biology
The ecological pressures that maintain the behavioral preferences of avian migrants, such as the timing and duration of nocturnal flights, remain elusive yet are critical to understand the evolution of the migratory program.
