Top‐Down and Bottom‐Up Processes Jointly Explain Mesopredator Movement and Foraging Ecology
Ecology Letters, Volume 29, Issue 3, March 2026.This study integrates top‐down (polar bear habitat selection) and bottom‐up (fish distribution) processes to test how mesopredators (ringed seals) balance risk–reward tradeoffs in habitat selection. Ringed seals reduced their space use and foraging time in response to predation risk, yet accepted higher risk when prey diversity was elevated ...

Global Ecology and Conservation, 2018 Small and declining populations of large mammals are vulnerable to stochastic events and can be at high risk of extinction. Population viability is also susceptible to the detrimental effects of low genetic diversity and inbreeding. The objective of this

Mammal Review, Volume 56, Issue 1, March 2026.Black bears as apex predators. American black bears can (1) produce top‐down effects on ungulates equal to or exceeding those of typical apex predators and (2) modify the spatiotemporal behaviour of other carnivores, including pumas and coyotes. We argue that the term ‘apex predator’ is highly context dependent and not a species‐wide status.

New Phytologist, Volume 249, Issue 5, Page 2251-2262, March 2026.Summary Soil nutrients and vertebrate herbivory are key ecological factors with opposite and interactive effects on grassland plant traits and biomass. Partitioning trait changes into species turnover and intraspecific change provides a mechanistic linkage between trait shifts and biomass responses.

Influence of ground substrate on establishment of reindeer lichen after artificial dispersal [PDF]
, 2007 Methods to improve the recovery of reindeer lichen after soil disturbance or overgrazing are being sought for areas where reindeer are herded. The effects of four substrates – mineral soil, moss, twigs and pine bark – on the establishment of lichen ...
