Generalist With a Narrow Niche Breadth: Feeding Ecology and Seed Germination Effectiveness of a Large Canid Within a Silvicultural Matrix

open access: yesAustral Ecology, Volume 51, Issue 6, June 2026.
Diet: The generalist canid exhibits a narrow niche breadth (0.12), consuming native plants (100% frequency) and animals (85%). Birds dominate animal prey (74%), peaking in the dry season, while Solanaceae plants dominate plant food (100%), peaking in the rainy season.

Barley seed quality under harvest management practices

open access: yesCrop Science, Volume 66, Issue 3, May/June 2026.
Abstract Barley (Hordeum vulgare L.) has a strategic role in global agriculture due to its use in food, feed, and brewing industries and its adaptability to diverse environments. This study evaluated the effect of harvest timing on seed quality in two commercial cultivars (ABI Rubi and ABI Valente), focusing on physical integrity, physiological ...

Landscape features predict broad‐scale seed rain patterns across fragments of the Brazilian Atlantic Forest

open access: yesJournal of Ecology, Volume 114, Issue 5, May 2026.
Along with precipitation, forest cover emerges as a fundamental driver of alpha and beta diversity in the seed rain. This highlights the role of habitat amount at the landscape level over patch‐level features, like patch size, for seed dispersal. However, increased seed density can be related to higher dispersal rates in forest borders.

The Red Queen unveils the sexual and mating strategies of flowers

open access: yesJournal 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.

Frost Decreases Fruit Production in a Neotropical Savanna: Implications for Frugivorous Bird Abundances

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Severe frost events seem to be happening on average every 5 years, rather than 7 years, as previously reported in the southern limit of the Cerrado, a Neotropical savanna. We conducted this study in the Cerrado, where severe frost events allowed us to compare fruit production and frugivorous bird abundance before and after the disturbance.
