Diel and Spatial Dependence of Humpback Song and Non-Song Vocalizations in Fish Spawning Ground

Remote Sensing, 2016
The vocalization behavior of humpback whales was monitored over vast areas of the Gulf of Maine using the passive ocean acoustic waveguide remote sensing technique (POAWRS) over multiple diel cycles in Fall 2006.

Artificial supplementary food influences hedgehog occupancy and activity patterns more than predator presence or natural food availability

Wildlife Biology, EarlyView.
Supplementary feeding for declining hedgehog Erinaceus europaeus populations is popular in Great Britain and has been suggested as an important factor in explaining higher densities in urban areas compared with rural ones. Occupancy modelling was used to test whether spatial variation in supplementary feeding, natural food, habitat, or predator ...

The wolf is back! Non‐consumptive effects of the return of a large carnivore on the use of supplementary feeding sites by roe deer

Wildlife Biology, EarlyView.
Understanding how prey species tradeoff predation risk and resource acquisition is particularly important for advancing our knowledge of predator–prey relationships. We investigated this by studying the use of concentrated anthropogenic resources, namely supplementary feeding sites, by roe deer Capreolus capreolus before and after grey wolf Canis lupus

Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae) in a tropical sandy beach, Southeastern Brazil

Brazilian Journal of Oceanography
The feeding ecology of the beach silverside (Atherinella blackburni) in the surf zone of a tropical sand beach, located in the southeastern Brazil, was accessed through the gut content analysis of 198 fish.

First record of humpback whale songs in Southern Chile: Analysis of seasonal and diel variation [PDF]

, 2018
Male humpback whales (Megaptera novaeangliae) produce complex, patterned songs that are traditionally recorded on their breeding grounds. In this work, we report results from the first continuous acoustic monitoring of a humpback whale feeding ground off

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Trematode infection buffers heat stress in blue mussels Mytilus edulis: The role of heat shock proteins

Journal of Animal Ecology, EarlyView.
The study shows that parasite infection changes heat shock protein expression and can increase heat tolerance in blue mussels. By separating parasite and temperature effects, the results suggest that infection may improve survival during heat stress, highlighting important parasite–host interactions for climate change resilience. Abstract The influence

Habitat Features, Coyotes, and Humans Drive Diel Activity Variation Among Sympatric Mammals

Integrative Zoology, EarlyView.
We found that multiple mammal species show considerable variation in diel activity in response to several factors, with biotic variables (habitat features and the presence of coyotes Canis latrans) having the strongest overall effects. Our results have important implications for trophic dynamics. Future studies will need to account for these underlying
