Loggerhead marine turtles (Caretta caretta) nesting at smaller sizes than expected in the Gulf of Mexico: Implications for turtle behavior, population dynamics, and conservation

open access: yesConservation Science and Practice, 2022
Estimates of parameters that affect population dynamics, including the size at which individuals reproduce, are crucial for efforts aimed at understanding how imperiled species may recover from the numerous threats they face.

Pronounced Seasonal Diet Diversity Expansion of Golden Eagles (Aquila chrysaetos) in Northern Greece during the Non-Breeding Season: The Role of Tortoises

open access: yesDiversity, 2022
Golden Eagles are resident in Greece and known to feed mainly on tortoises when breeding. However, information on alternative prey is scarce, especially during the tortoise brumation, that roughly coincides with the eagles’ non-breeding season.

A four-questions perspective on public information use in sticklebacks (Gasterosteidae) [PDF]

open access: yesRoyal Society Open Science, 2019
Whether learning primarily reflects general processes or species-specific challenges is a long-standing matter of dispute. Here, we present a comprehensive analysis of public information use (PI-use) in sticklebacks (Gasterosteidae).

Traces of a Neonicotinoid Induce Precocious Foraging and Reduce Foraging Performance in Honey Bees.

open access: yesEnvironmental Science and Technology, 2019
There is increasing worldwide concern about the impacts of pesticide residues on honey bees and bee colony survival, but how sublethal effects of pesticides on bees might cause colony failure remains highly controversial, with field data giving very ...

Seagrass Meadows Provide a Significant Resource in Support of Avifauna

open access: yesDiversity, 2021
Seagrass meadows are known to be rich in fauna, with complex food webs that provide trophic subsidy to species and habitats way beyond the extent of their distribution. Birds are an often-overlooked part of marine ecosystems; not only are they crucial to

Fidelity to foraging sites after long migrations.

open access: yesJournal of Animal Ecology, 2019
Patterns of animal movement associated with foraging lie at the heart of many ecological studies and often animals face decisions of staying in an environment they know, versus relocating to new sites.
