The Red Queen unveils the sexual and mating strategies of flowers

Journal of Ecology, Volume 114, Issue 5, May 2026.
Although the conventional wisdom is that floral traits of plants evolved in concert with their mutualistic pollinators, here we showed that several key sexual and mating traits of plants, which modulate their outcrossing strategy, evolved in response to the pressure exerted by their antagonistic insect herbivores.

Riqueza e abundância de herbívoros em flores de Vellozia nivea (Velloziaceae) Richness and abundance of herbivores on Vellozia nivea (Velloziaceae) flowers

Acta Botânica Brasílica, 1998
Vellozia nivea (Velloziaceae) é planta de porte herbáceo que ocorre em solos rochosos, nos campos rupestres da Serra do Cipó, MG. Suas flores hermafroditas são extremamente macias, representando fonte tenra de alimento para os insetos que predam suas ...

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

Population ecology of Paepalanthus polyanthus: predispersal hazards and seed production Ecologia populacional de Paepalanthus polyanthus: riscos de pré-dispersão e produção de sementes

Acta Botânica Brasílica, 2000
This study aimed at evaluating seed production and predispersal hazards in a sand dune population of P. polyanthus (Eriocaulaceae) in Southern Brazil. Bad development of flowering capitula was caused by the wind and by interference among umbels.

Global insular leaf size shifts follow the island rule, independently of insect herbivory and macroclimate

Journal of Ecology, Volume 114, Issue 2, February 2026.
We found a positive, non‐linear, saturating relationship between mainland and island leaf sizes, reflecting an island rule‐like pattern. Small‐leaved mainland species tend to develop larger leaves on islands, while this effect weakens for larger‐leaved species, a pattern consistent across both conspecific and congeneric comparisons. Abstract The island

Feeding habits of coypu (Myocastor coypus Molina 1978) in the wetlands of the Southern region of Brazil

Anais da Academia Brasileira de Ciências, 2010
The aim of this study was to determine the diet of coypu (Myocastor coypus) in two areas (Santa Isabel do Sul wetlands - Area 1, and Santa Marta Farm - Area 2) in the Southern region of Brazil, using microhistological analyses of feces. Twenty-four plant
