Histological and Gene Expression Analyses of the Arm and Finger Macroglands of Two Hyloxalus Frogs (Dendrobatidae)

Molecular Ecology, Volume 34, Issue 22, November 2025.
ABSTRACT Chemical communication during courtship is well documented in salamanders and newts, but its role in frogs is less understood. In some Neotropical poison frogs, males exhibit specialised mucous glands (SMGs) in the hand integument that express high levels of sodefrin precursor‐like factors (SPFs), an amphibian pheromone. Some species also show

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.

Environmental and Geographic Conditions on the Breeding Grounds Drive Bergmannian Clines in Nightjars

Journal of Biogeography, Volume 52, Issue 10, October 2025.
ABSTRACT Aim To evaluate (1) whether three migratory nightjar species (Family Caprimulgidae) adhere to Bergmann's rule, (2) whether environmental factors on the breeding or wintering grounds determine body size, and (3) which mechanistic hypotheses best explain Bergmannian patterns in body size.

Demographic performance review of a reintroduction project: Iberian lynx in Extremadura

Journal of Applied Ecology, Volume 62, Issue 9, Page 2189-2201, September 2025.
Demographic performance reviews are essential for understanding the drivers of population growth and for evaluating the outcomes of reintroduction initiatives. IPMs as exemplified by our Iberian lynx case study provide a powerful and flexible framework for quantifying reintroduction performance and addressing key research and management questions.
