The future of endemic and threatened birds of the Amazon in the face of global climate change
Ecology and EvolutionThe anthropogenic impacts on the environment, including deforestation and the escalating emissions of greenhouse gases, have significantly contributed to global climate change that can lead to alterations in ecosystems.

A hierarchical theory of macroecology [PDF]
Ecology Letters, 2012 AbstractThe relationships of local population density (N) with body size (M) and distribution (D) have been extensively studied because they reveal how ecological and historical factors structure species communities; however, a unifying model explaining their joint behaviour, has not been developed.

Warming summers limit reindeer grazing, weakening herbivory pressure in the mountain tundra
Ecography, EarlyView.Climate change is predicted to alter species interactions by exposing ecosystems to increasingly frequent and intense warm spells. In the mountain tundra, grazing by large herbivores, particularly reindeer, can limit shrub expansion and preserve Arctic plant diversity.

A second horizon scan of biogeography: Golden Ages, Midas touches, and the Red Queen
Frontiers of Biogeography, 2016 Are we entering a new ‘Golden Age’ of biogeography, with continued development of infrastructure and ideas? We highlight recent developments, and the challenges and opportunities they bring, in light of the snapshot provided by the 7th biennial meeting ...

Vegetation on the move: elevational shifts and greening dynamics across the Himalayan alpine zone
Ecography, EarlyView.This study investigates alpine ‘vegetation line' (the upper limit of continuous plant community) dynamics in the Himalayan alpine zone (HAZ) over a 24‐year timescale (1999–2022) using maximum NDVI products derived from Landsat series datasets, adjusted for sampling bias using phenological modelling.

Integrating the Ecosystem Services Framework to Define Dysbiosis of the Breastfed Infant Gut: The Role of B. infantis and Human Milk Oligosaccharides [PDF]
, 2020 Mounting evidence supports a connection between the composition of the infant gut microbiome and long-term health. In fact, aberrant microbiome compositions during key developmental windows in early life are associated with increased disease risk ...

Ecography, EarlyView.The transferability of single or joint species distribution models ((j)SDMs) depends on their ability to predict beyond the observed environmental range and to remain consistent despite shifts in biotic interactions. Transfer accuracy may be improved by recent advances in the application of deep learning that provide greater flexibility and potentially

Ecography, EarlyView.Ocean warming is driving the redistribution of species at a global scale. Biogeographic transition zones are hotspots of species range shifts, as both warm‐ and cold‐adapted species are found toward contrasting range edges. While anecdotal evidence suggests some distributional shifts have occurred in the northeast Atlantic, the empirical evidence base ...

Methods in Ecology and Evolution, 2023 Locally observed biodiversity always consists of only a fraction of its site‐specific species pool. Why some suitable species are absent, shaping dark diversity of that site, is a basic yet increasingly crucial question in the face of global biodiversity

EcoClimate: a database of climate data from multiple models for past, present, and future for macroecologists and biogeographers [PDF]
, 2015 Studies in biogeography and macroecology have been increasing massively since climate and biodiversity databases became easily accessible. Climate simulations for past, present, and future have enabled macroecologists and biogeographers to combine data ...
