Beyond first clutches: Second broods reshape selection on breeding timing in forest and urban great tits

Journal of Animal Ecology, EarlyView.
Most studies of selection on breeding timing consider only first clutches. Using a 13‐year dataset of urban and forest great tits, we show that including second broods reshapes estimates of natural selection, revealing that early breeding is favoured through increased probability of multiple brooding and higher annual reproductive output.

Asymmetric niche partitioning in large omnivores in response to anthropogenic disturbances within subarctic ecosystems

Journal of Animal Ecology, EarlyView.
Anthropogenic disturbances associated with mineral extraction influenced space use and activity patterns in grizzly bears, and to a much lesser extent in black bears, in a subarctic ecosystem, signalling an asymmetric response. Abstract Niche partitioning is an evolutionary process that allows the coexistence of multiple species in a landscape. However,

Social organization and habitat use shape the gut microbiome of a marine fish

Journal of Animal Ecology, EarlyView.
This study provides the first evidence linking habitat use—and to a lesser extent social organization—to gut microbiome composition in a wild marine fish. The results indicate that local habitat conditions are the primary driver of microbial variation, while social effects are detectable but weak.

Snowmelt predicts earlier breeding across the latitudinal range of an Arctic nesting seabird, the Little Auk (Alle alle)

Journal of Animal Ecology, EarlyView.
Multi‐year monitoring of the crevice‐nesting High Arctic seabird, the Little Auk (Alle alle), across four colonies spanning distinct climatic regimes revealed that snowmelt timing is a key and consistent driver of breeding phenology. Earlier snowmelt advances access to nesting habitat, enabling birds to initiate reproduction sooner. These findings show

Elephant space use and habitat selection change across drought timescales

Journal of Animal Ecology, EarlyView.
Drought threatens wildlife worldwide, but little is known about wildlife behaviour during drought. This study combines 19 years of elephant GPS data with drought conditions at three timescales. Key findings include that elephants (i) move less during drought at a 1‐month timescale and (ii) change habitat selection across drought timescales.
