Ecología Austral, 1998 In order to gain insight about why Patagonia has low levels of granivory activity, percentages of world-wide granivory rates were compared for rodents, ants, and birds in seven desertic areas of the world.

Laboratory study of larval food requirements in nine species of Amara (Coleoptera: Cara-bidae)
Plant Protection Science, 2001 Food requirements of the larvae of nine closely related species of the genus Amara (Coleoptera: Carabidae) were studied in the laboratory. Mealworms, a mixed diet of mealworms and oat flakes, and seeds of Capsella bursa-pastoris and Stellaria media were ...

Global patterns in post-dispersal seed removal by invertebrates and vertebrates. [PDF]
PLoS ONE, 2014 It is commonly accepted that species interactions such as granivory are more intense in the tropics. However, this has rarely been tested. A global dataset of post-dispersal seed removal by invertebrates and vertebrates for 79 native plant species from ...

Variation in seed abundance predicts yolk fatty acid composition in a wild population of birds
Journal of Avian Biology, Volume 2026, Issue 2, March 2026.Bird embryos develop inside eggs, which contain maternal substances that can shape offspring phenotype and fitness. Yolk fatty acids are a key energy source for the developing embryo, with omega‐6 (ω‐6) and omega‐3 (ω‐3) polyunsaturated fatty acids (PUFAs) obtained exclusively from the diet.

Ecosphere, 2016 Cities annex wilderness and alter the interactions between the plant and animal assemblages embedded in the remaining nature fragments. Here, we explore consequences of habitat fragmentation for dispersal of cactus by fruit‐eating mammals in the Sonoran ...

Ecology, 2014 Seed predation is an important biotic filter that can influence abundance and spatial distributions of native species through differential effects on recruitment. This filter may also influence the relative abundance of nonnative plants within habitats and the communities' susceptibility to invasion via differences in granivore identity, abundance, and

Population Ecology, Volume 68, Issue 1, January 2026.This study assessed the impact of seedling reintroduction and protection on the vulnerable cactus Cephalocereus polylophus using a 5‐year dataset and integral projection models. Results showed that although seedling protection increased survival and population size slightly, the overall growth rate remained below one due to limited recruitment and ...

Revista Chilena de Historia Natural, 2023 Background Little is known about the California Quail (Callipepla californica) as an invader in Chile and Argentina. Our goal was to review the history of its introduction and to provide updated information on its spread and current geographic ...

Ecology, 2011 Escape from specialist natural enemies is frequently invoked to explain exotic plant invasions, but little attention has been paid to how generalist consumers in the recipient range may influence invasion. We examined how seed preferences of the widespread generalist granivore Peromyscus maniculatus related to recruitment of the strongly invasive ...
