Past and present disturbances generate spatial variation in seed predation
Ecosphere, 2020 Seed survival is a key process for plant populations; variation in the activity and abundance of animals that consume seeds can lead to dramatic shifts in seed fate.

Ecosphere, 2017 Escaping seed predation is a classic “economy of scale” hypotheses (predator satiation hypothesis, Psh) to explain the selection for the synchronous production of massive and nil seed crops (masting) in plants.

European Journal of Entomology, 2014 Carabid beetles could potentially provide a number of ecosystem services in arable fields, including the regulation of weeds by eating seeds. Spatio-temporal variability in the incidence of predation combined with a limited understanding of the ...

Patterns of granivory in Acacia cyclops stands under biological control at Langebaanweg, South Africa [PDF]
, 2016 Low seed abundance associated with effect of biological control agents in an invasive shrub Acacia cyclops may limit its seed banks and further spread of the remaining seed crop in the South-western Cape, South Africa.

Cafeteria-style experiments for granivory and its methodologial issues [PDF]
, 2018 La oferta de semillas ha sido el método más usado en los estudios experimentales de granivoría. Estos experimentos presuponen que las semillas faltantes en cada tratamiento han sido consumidas por los granívoros, y que el consumo experimental es similar ...

Host-Parasite Interactions from the Inside: Plant Reproductive Ontogeny Drives Specialization in Parasitic Insects. [PDF]
PLoS ONE, 2015 Host plant interactions are likely key drivers of evolutionary processes involved in the diversification of phytophagous insects. Granivory has received substantial attention for its crucial role in shaping the interaction between plants and their seed ...

Toward reliable estimates of seed removal by small mammals and birds in the Neotropics
Brazilian Journal of BiologyBirds are often considered seed predators of less importance when compared to rodents or granivorous ants in studies of seed predation using selective exclosures.

Ecography, EarlyView.Animal coloration exhibits substantial biogeographic variation, reflecting complex adaptations to both abiotic and biotic environments. Although the evolutionary mechanisms underlying avian plumage coloration have been widely studied, geographic variation in plumage patterning has received far less attention.

Quantifying granivory in a reconstructed prairie: affects of season, species, seed predators, sacrificial food, and the chemical deterrent capsaicin [PDF]
, 2007 Floral diversity of reconstructed prairies is often low compared to remnant prairies. Studies have demonstrated it is feasible to increase forb diversity in these prairies through overseeding and mowing, but overall rates of seedling establishment range ...

Oikos, EarlyView.Understanding how different drivers of global change interact to shape ecological processes remains a major challenge in ecology. Climate change is reshuffling the interactions that structure communities, with major implications for biological invasions.
