Salty suitors: High larval sodium intake reduces adult lifespan and influences reproductive behaviour in a lepidopteran herbivore

Ecological Entomology, Volume 50, Issue 5, Page 886-898, October 2025.
Low‐sodium females took significantly longer to start mating than high‐sodium females, but no pairings differed in the duration of copulation. Reproductive outputs, measured by number of clutches, hatching young, adult offspring and pupation time, did not differ across parental sodium pairings.

Domestic cat penetrability into rural and natural habitats of the Iberian Peninsula

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Free‐roaming domestic cats in the Iberian Peninsula regularly venture into rural and natural areas, with some individuals travelling over 2 km from their homes. Our GPS tracking data from 64 cats reveal that younger, neutered and owned cats show larger home ranges and greater penetration into natural habitats, raising concerns for native biodiversity ...

Rapid Ocean Warming Drives Sexually Divergent Habitat Use in a Threatened Predatory Marine Ectotherm

Global Change Biology, Volume 31, Issue 7, July 2025.
How ectothermic, mobile marine predators are responding to climate change is uncertain due to lack of species‐specific data, which can mask the true impact of this threat. We investigate the impact of environmental conditions and thermal extremes on the behavior and distribution of angelsharks, a highly threatened elasmobranch of global conservation ...

Delineating ecologically distinct groups for annual cycle management of a declining shorebird

Journal of Applied Ecology, Volume 62, Issue 5, Page 1152-1165, May 2025.
Using measurements of migratory connectivity in concert with expert opinion can define ecologically distinct groups for wildlife management that differ in the environmental conditions they experience across seasons of the annual cycle, which is a key component for understanding and reversing declines of migratory species. Abstract Patterns of migratory

Chemical ecology of symbioses in cycads, an ancient plant lineage

New Phytologist, Volume 246, Issue 4, Page 1494-1504, May 2025.
Summary Cycads are an ancient lineage of gymnosperms that maintain a plethora of symbiotic associations from across the tree of life. They have myriad morphological, structural, physiological, chemical, and behavioral adaptations that position them as a unique system to study the evolution, ecology, and mechanism of symbiosis.

Sex‐Specific Variation in Foraging Behavior is Related to Telomere Length in a Long‐Lived Seabird

Ecology and Evolution, Volume 14, Issue 12, December 2024.
Foraging during breeding is energetically demanding, intimately linked to breeding investment, and possibly constrained by individual condition. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic maintenance and individual quality. We found that brown booby females with longer
