Role of freshwater availability and terrestrial land‐cover change in the distribution of a declining, terrestrial, insectivorous bird

open access: yesConservation Biology, EarlyView.
Abstract Insectivorous, Afro‐Palearctic migrant birds provide cross‐border ecosystem services, but many are declining rapidly. The complex life cycle of migrant birds makes their conservation difficult, but understanding where they spend time during the breeding season can help indicate where those actions will be most effective.

Environmental DNA for invasive rat surveillance and biosecurity on islands

open access: yesConservation Science and Practice, EarlyView.
We collected aquatic eDNA samples from beach and lake sites on three atoll islands with different invasion statuses before and after a rat eradication operation. Two dozen eDNA samples can confirm with ≥95% probability the presence of invasive rats prior to any management intervention. However, following the eradication operation, neither targeted eDNA

Integrating ecological feedbacks across scales and levels of organization

open access: yesEcography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

What Goes First? Effects of Starvation on the Body Condition of a Neotropical Dung Beetle

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We investigated how prolonged starvation affects key physiological traits in the dung beetle Dichotomius bos. Prolonged starvation leads to significant reductions in body dry mass and fat reserves, while muscle mass remains unchanged. These findings indicate that dung beetles prioritize the maintenance of locomotor muscles while mobilizing stored ...
