Trade-offs between the risks of predation and starvation in subtropical granivorous finches [PDF]

open access: yes, 2007
Animal community structures, life histories and individual foraging behaviour are all an outcome of a trade-off between competition for resources (and thus the risk of starvation) and survival (and thus the risk of predation).

The fear diet: Risk, refuge, and biological control by omnivorous weed seed predators

open access: yesBasic and Applied Ecology, 2022
Weed seed biocontrol by omnivorous mice and insects can limit weed seedbanks, but this ecosystem service can be difficult to predict given the broad diet breadth of seed predators and their potential for intraguild predation.

Generalist predators disrupt parasitoid aphid control by direct and coincidental intraguild predation [PDF]

open access: yes, 2011
Generalist predators and parasitoids are considered to be important regulators of aphids. The former not only feed on these pests, but might also consume parasitoids at all stages of development.

Factors influencing seed predation in rainforest tree communities of subtropical Australia: Fragmentation, seed size and shifts in vertebrate assemblages

open access: yes, 2021
Rainforest fragmentation has large impacts on ground-active vertebrates, including granivorous mammals (e.g., rodents), and birds. We tested for differences in community-wide patterns of interference with seeds of rainforest trees, between fragments and ...

Does increasing the diversity of seeds broadcast for restoration alter post‐dispersal seed predation and its community‐determining effects?

open access: yesEcological Solutions and Evidence, 2023
Native seeds broadcast for restoration are often consumed by predators before they can germinate. However, it is unclear how the composition of a seed mix affects seed predation.

An omnivorous mesopredator modifies predation of omnivore‐dispersed seeds

open access: yesEcosphere, 2021
Post‐dispersal seed predation is an important determinant of plant recruitment. Although many plant species are dispersed following consumption by omnivorous vertebrates, the potential for these dispersal agents to indirectly affect seed fate by ...

Protection against insect predation during fruit development: the role of fleshy fruit wings of three species of Zygophyllum in the cold desert of Central Asia

open access: yesFrontiers in Plant Science, 2023
IntroductionFruit wings serve various ecological functions, including facilitating wind dispersal, providing physical protection to seeds, and regulating seed germination.

Tracking Seed Fates of Tropical Tree Species: Evidence for Seed Caching in a Tropical Forest in North-East India. [PDF]

open access: yesPLoS ONE, 2015
Rodents affect the post-dispersal fate of seeds by acting either as on-site seed predators or as secondary dispersers when they scatter-hoard seeds. The tropical forests of north-east India harbour a high diversity of little-studied terrestrial murid and

Empty seeds are not always bad: simultaneous effect of seed emptiness and masting on animal seed predation. [PDF]

open access: yesPLoS ONE, 2013
Seed masting and production of empty seeds have often been considered independently as different strategies to reduce seed predation by animals. Here, we integrate both phenomena within the whole assemblage of seed predators (both pre and post-dispersal)

Biotic resistance to plant invasion in grassland: Does seed predation increase with resident plant diversity? [PDF]

open access: yes, 2014
Seed predation impacts heavily on plant populations and community composition in grasslands. In particular, generalist seed predators may contribute to biotic resistance, i.e.
