Decline of parasitic and habitat-specialist species drives taxonomic, phylogenetic and functional homogenization of sub-alpine bumblebee communities
(Peer reviewed; Journal article, 2021)The ongoing biodiversity crisis is characterised not only by an elevated extinction rate but also can lead to an increasing similarity of species assemblages. This is an issue of major concern, as it can reduce ecosystem ... -
Global analysis of seasonal changes in trematode infection levels reveals weak and variable link to temperature
(Peer reviewed; Journal article, 2023)Seasonal changes in environmental conditions drive phenology, i.e., the annual timing of biological events ranging from the individual to the ecosystem. Phenological patterns and successional abundance cycles have been ... -
Marked differences in foraging area use and susceptibility to predation between two closely-related tropical seabirds
(Peer reviewed; Journal article, 2023)Ecological theory predicts that closely-related species must occupy diferent niches to coexist. How marine top predators achieve this during breeding, when they often gather in large multi-species colonies and are constrained ... -
Nonlinear spatial and temporal decomposition provides insight for climate change effects on sub-Arctic herbivore populations
(Peer reviewed; Journal article, 2022)Global temperatures are increasing, afecting timing and availability of vegetation along with relationships between plants and their consumers. We examined the efect of population density, herd body condition in the previous ... -
Resources and predation: drivers of sociality in a cyclic mesopredator
(Peer reviewed; Journal article, 2022)In socially fexible species, the tendency to live in groups is expected to vary through a trade-of between costs and benefts, determined by ecological conditions. The Resource Dispersion Hypothesis predicts that group size ... -
Short‑lived species move uphill faster under climate change
(Peer reviewed; Journal article, 2022)Climate change is pushing species ranges and abundances towards the poles and mountain tops. Although many studies have documented local altitudinal shifts, knowledge of general patterns at a large spatial scale, such as ... -
