Ungulate presence and predation risks reduce acorn predation by mice in dehesas [PDF]
PLoS ONE, 2022 Foraging decisions by rodents are key for the long-term maintenance of oak populations in which avian seed dispersers are absent or inefficient. Decisions are determined by the environmental setting in which acorn-rodent encounters occur.

Overcoming Obstacles: Perspective on How Mediterranean Oaks Defend Their Acorns from Insect Seed Predators [PDF]
InsectsInsect pre-dispersal seed predators attack a large proportion of the acorn crops in oak forests worldwide. Oaks (Quercus spp.) have evolved several strategies, including physical barriers, chemical defenses (e.g., tannins), and/or phenological predator ...

Acorn Weevil Species Diversity and Host Affinity in the Semi-Humid Evergreen Broad-Leaved Forests of Southwest China [PDF]
InsectsAcorn weevils critically impact forest regeneration in semi-humid evergreen broad-leaved forests (SEBFs) by parasitizing and consuming acorns before dispersal.

Acorn Crop, Seed Size and Chemical Defenses Determine the Performance of Specialized Insect Predators and Reproductive Output in a Mediterranean Oak [PDF]
Insects, 2021 Seed predation is an antagonistic interaction that negatively affects the performance of individual plants and can limit plant population dynamics. In animal-dispersed plants, crop size is an important determinant of plant reproductive success through ...

Seed Dispersal by Ants in Three Early-Flowering Plants [PDF]
Insects, 2022 Interactions between ants and plants vary from being occasionally beneficial to neutral and negative. Ant-mediated dispersal of obligatory myrmecochorous plants is considered mutualistic interaction, providing benefits to plants in terms of seed ...

The fruit morphometric variation and fruit type evolution of the stone oaks (Fagaceae, Lithocarpus) [PDF]
BMC Plant Biology, 2023 Background The great species diversity of Lithocarpus is associated with interspecific fruit morphological variation, represented by acorn (AC) and enclosed receptacle (ER) fruit types.

Grain-for-green accelerates functional restoration of rodent-mediated seed dispersal
Ecological Indicators, 2023 The Grain-for-Green Program in China is one of the largest payments for ecosystem services programs, and it is regarded as effective for protecting the ecological environment and mitigating disasters. However, research into the effects of revegetation on

The Interplay among Acorn Abundance and Rodent Behavior Drives the Spatial Pattern of Seedling Recruitment in Mature Mediterranean Oak Forests. [PDF]
PLoS ONE, 2015 The patterns of seedling recruitment in animal-dispersed plants result from the interactions among environmental and behavioral variables. However, we know little on the contribution and combined effect of both kinds of variables.
