It is cool to be clear: Transparency induces a thermal cost in clearwing butterflies

open access: yesFunctional Ecology, Volume 39, Issue 9, Page 2452-2464, September 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract In butterflies, wing transparency raises the question of potential costs for vital functions, such as thermoregulation. The thermal melanism hypothesis posits that darker colorations enable higher absorption of solar radiation, leading to the prediction that such ...

Observaciones generales de la dieta del zanate mexicano Quiscalus mexicanus en Puerto Vallarta, México

open access: yesHuitzil, 2017
We reported photographic evidence of Great-tailed Grackle Quiscalus mexicanus predation on species Sceloporus melanorhinus (Black-nosed lizard) and Iguana iguana (Green iguana), and its cannibalism of eggs, in an urban area of Puerto Vallarta, Mexico. We

Behavioural co‐option of plant secondary compounds by a cavity‐nesting bird is an adaptation against competition and predation

open access: yesFunctional Ecology, Volume 39, Issue 2, Page 362-370, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Interactions with competitors and predators can generate strong selection and favour the evolution of novel strategies for mitigating fitness costs. Adaptations to mitigate competition and predation risk often involve evolution of traits which directly reduce costs ...

Butterfly species vary in sex‐specific sodium accumulation from larval diets

open access: yesEcological Entomology, Volume 50, Issue 1, Page 228-234, February 2025.
Male butterflies accumulate more sodium than females in three butterfly species, especially when larvae were exposed to high dietary sodium concentrations. Sodium bioaccumulation occurred mainly in Low Na treatments and bioexcretion was highest in females on High Na diets.

Testing the contribution of vertebrate predators and leaf traits to mainland–island differences in insect herbivory on oaks

open access: yesJournal of Ecology, Volume 113, Issue 1, Page 140-154, January 2025.
The authors explored how insularity influences herbivory in oaks across island–mainland sites. By experimentally excluding vertebrate predators (e.g. birds, bats) and measuring leaf traits (e.g. phenolics, specific leaf area, nutrients), they provide insights into the mechanisms driving island–mainland herbivory patterns.
