Monitoring Pacific walrus coastal haulouts by satellite to estimate herd abundance and distribution

open access: yesWildlife Society Bulletin, EarlyView.
We monitored Pacific walrus haulouts with drone and satellite imagery to derive new methods for estimating minimum population size. The largest herd observed during an 8‐year study period was on the coast of northeastern Russia at Cape Serdtse‐Kamen in autumn 2022 where the aggregation spanned over an area of 184,094 m2 with a mean density (and 90 ...

Scaling the effects of size and temperature on animal consumption rates from individuals to populations in a subtropical reef fish

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Measuring how temperature and body size drive individual consumption rates is fundamental to predict how climate change might shape population‐level consumption pressure. Yet, such measurements remain rare.

Stochastic variation in temperature and food availability impacts growth, but not metabolic rate and exploration in a juvenile amphibian

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract A substantial proportion of environmental variation is stochastic. While environmental stochasticity plays a key role in the evolution of phenotypic strategies, its short‐term effects within generations remain poorly understood. These short‐term organismal responses are
