Shelters or ecological traps? Context‐dependent effects of nestboxes on breeding success in a colonial raptor

open access: yesIbis, EarlyView.
Artificial breeding structures, such as nestboxes, can potentially influence the population size and conservation status of bird species relying on heavily human‐modified environments such as agroecosystems and urban areas. However, the effectiveness of these interventions may vary, as artificial structures could attract individuals to suboptimal ...

Too hot for comfort: Elevated temperatures influence gene expression and exceed thermal tolerance of bigmouth shiners, Ericymba dorsalis

open access: yesJournal of Fish Biology, EarlyView.
Abstract Environmental and associated ecosystem change may affect the persistence of fish species based on their ability to adapt to changing conditions, including decreasing flows and rising water temperatures. Exceeding the thermal tolerances of stream fish will likely result in a loss of ability to maintain metabolic processes.

Nonapeptide cell size differs between male morphs of the West African cichlid, Pelvicachromis pulcher

open access: yesJournal of Fish Biology, EarlyView.
Abstract Alternative male morphs are found in many species of fishes. These morphs often differ in suites of social behaviours, such as aggression and territoriality, associated with alternative reproductive tactics. Such consistent morph‐typical behavioural profiles suggest common differences in underlying neuroendocrine mechanisms.

Assessment of two minimally invasive methodologies for sex identification in the European eel, Anguilla anguilla

open access: yesJournal of Fish Biology, EarlyView.
Abstract Sex is an important driver of variation in behaviour, ecology and physiology. Sex identification in the Critically Endangered European eel (Anguilla anguilla) currently requires fish sacrifice, or the use of morphological differences such as body length, which can be inaccurate in certain habitats and at intermediate body lengths.

Osteology and arthrology of the ankle and tarsometatarsus of anoles (Iguania: Anolidae): not convergent with geckos but divergent from the ancestral iguanian condition

open access: yesJournal of Anatomy, EarlyView.
Geckos and anoline iguanid lizards are well‐known for their possession of adhesive toepads, which are generally regarded as being convergent structures. We show that the anatomical configuration of the foot in these two lineages differs markedly and that these differences likely relate to the contrasing ways they deploy their adhesive systems and ...
