Acorn dispersal effectiveness after 27 years of passive and active restoration in a Neotropical cloud forest

open access: yesScience of the Total Environment
Ecological restoration can mitigate the negative effects of loss and degradation of natural ecosystems. However, the efficacy of restoration strategies (active vs. passive) in recovering crucial ecological interactions such as animal seed dispersal remains largely unknown. We evaluated the seed dispersal effectiveness of Quercus insignis, an endangered

Acorn dispersal by rodents: The importance of re-dispersal and distance to shelter

open access: yesBasic and Applied Ecology, 2011
Abstract Factors affecting the ecological balance between seed predation and effective seed dispersal remain unclear. We studied the contribution of scatter-hoarding rodents to effective acorn dispersal by labeling acorns and tracking their fates.

Spatial decision-making in acorn dispersal by Eurasian jays around the forest edge: Insights into oak forest regeneration mechanisms [PDF]

open access: yesForest Ecology and Management, 2023
10 p.Seed dispersal is key to forest regeneration and often depends on the behavior of seed scatter-hoarding animals. However, our understanding of the decision-making of scatter-hoarders and how vegetation structure at different spatial scales affects ...

Acorn dispersal estimated by radio-tracking

Oecologia, 2007
Bird-dispersed seeds are difficult to track, especially in the case of long-distance dispersal events. To estimate the oak dispersal distance and the seed shadow generated by the European jay (Garrulus glandarius), we inserted radio-transmitters in 239 acorns, placed them in bird-feeders and then located them by radio-tracking.
