Seed predation of Sapindus saponaria L. by Leptostylus gibbulosus Bates (Coleoptera: Cerambycidae) and its effects on germination

Colombia Forestal, 2012
Seed predation has been considered as a selective process that decreases reproductive fitness of plant species. Fruits and seeds of Sapindus saponaria collected in Anolaima town, between 2009 and 2010 were used to characterize predation of Leptostylus ...

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

Functional 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 ...

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

Functional 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

Ecological 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

Journal 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.

Araucaria araucana and the Austral parakeet: pre-dispersal seed predation on a masting species El pehuén y la cachaña: depredación predispersión de una especie "masting"

Revista Chilena de Historia Natural, 2008
Pre-dispersal seed predation by Austral parakeets, Enicognathus ferrugineus, on pehuén, Araucaria araucana, was studied to assess the relationship between predation and seed production. We collected falling seeds in four araucaria forests of southwestern
