Characterization of animal communities involved in seed dispersal and predation of Guibourtia tessmannii Harms (J. Léonard), a species newly listed on Appendix II of CITES Royal Zoological Society of Antwerp
Characterization of the ecology of endangered timber species is a crucial step in
any forest management strategy. In this study, we described the animal communities involved in seed dispersal and predation of a high-value timber species Guibourtia tessmannii (Fabaceae; Detarioideae), which is newly listed on Appendix II of CITES. We compared the animal communities between two forest sites (Bambidie in Gabon and Ma’an in Cameroon). A total ...

Induced phenological avoidance : a neglected defense mechanism against seed predation in plants Ghent University
Characterization of animal communities involved in seed dispersal and predation of Guibourtia tessmannii (Harms) J.Léonard, a species newly listed on Appendix II of CITES Royal Zoological Society of Antwerp
Although Miconia mirabilis is a very common species in disturbed forest areas and is known for providing food resources for the local fauna, little is known about its reproductive phenology and other ecological aspects. The present study compares intra- and inter-annual patterns in the reproductive phenophases of that species in three distinct physiognomies of Atlantic Forest in Southeastern Bahia based on semi-quantitative observations ...
Spatio-temporal variation in seed predation by a native weevil in the invasive Prunus serotina Ghent University
Annual variation in predation and dispersal of Arolla pine (**Pinus cembra** L.) seeds by Eurasian red squirrels and other seed-eaters University of Antwerp
Seed predation and dispersal are key processes in the survival and distribution of plant species. Many animals cache seeds for later consumption, and, failing to recover some of these seeds, act as seed dispersers, influencing post-dispersal seed and seedling survival. Both animal and plant benefit from scatterhoarding and natural selection of seed characteristics and adaptations of seed predators (and dispersers) is one of the most important ...
The impact of habitat fragmentation on the interaction between Centaurium erythraea (Gentianaceae) and its specialized seed predator Stenoptilia zophodactylus (Pterophoridae, Lepidoptera) KU Leuven Ghent University
Habitat fragmentation can affect plant population characteristics and plant traits, which in turn can change biotic interactions, such as plant-insect interactions. Because of this, habitat fragmentation can affect reproductive success and survival of both the plant and seed predators, especially when the predator is rare and specialized. This study focuses on the level of fruit predation in Centaurium erythraea by its specific seed predator, ...
Horse dung germinable seed content in relation to plant species abundance, diet composition and seed characteristics Research Institute for Nature and Forest
The abundance and species richness of the germinable seed content of dung of free ranging horses was quantified and related to seven variables: plant species abundance in the field (cover) and in the horse diet, seed sizes (length, width and mass), seed longevity index and seed shape which was expressed as variance in seed dimensions. Analyses were run both across species, with species treated as independent data points, and for 40 ...
Dispersal and predation of diaspores of Coula edulis Baill. in an evergreen forest of Gabon Royal Zoological Society of Antwerp
The African walnut (Coula edulis) is a tree species of African evergreen forests, the seeds of which are collected and traded by African people. Many animal species consume African walnut diaspores; however, their roles as dispersers or predators have yet to be clarified. In this study, we present observations conducted in two different habitats of a Gabonese region over a 3-year period. The originality of this research resides in the ...
Evolution and ecology of seed internal morphology in relation to germination characteristics in Amaranthaceae KU Leuven Meise Botanic Garden
BACKGROUND AND AIMS: Internal seed morphological traits such as embryo characteristics and nutritive tissue can vary considerably within a plant lineage. These traits play a prominent role in germination processes and the success of seedling establishment, and are therefore under high selective pressure, especially in environments hostile to seedlings, such as arid, saline or highly dynamic habitats. We investigated the relationships of seed ...
