Seed-dispersal distributions by trumpeter hornbills in fragmented landscapes.
Frugivorous birds provide important ecosystem services by transporting seeds of fleshy fruited plants. It has been assumed that seed-dispersal kernels generated by these animals are generally leptokurtic, resulting in little dispersal among habitat fragments. However, little is known about the seed-dispersal distribution generated by large frugivorous birds in fragmented landscapes. We investig...
متن کاملTree diversity of the Dja Faunal Reserve, southeastern Cameroon
The Dja Faunal Reserve located in southeastern Cameroon represents the largest and best protected rainforest patch in Cameroon. Here we make available a dataset on the inventory of tree species collected across the Dja. For this study nine 5 km long and 5 m wide transects were installed. All species with a diameter at breast height greater than 10 cm were recorded, identified and measured. A to...
متن کاملSeed dispersal by neotropical seed predators.
From a plant's perspective, the difference between a seed predator and a seed disperser should be straightforward: attract animals that will disperse seeds and defend seeds from potential predators. Unlike pulp-eating frugivores, seed predators regularly encounter diverse plant protective mechanisms. The purpose of this paper is to examine feeding constraints, morphological adaptations, and the...
متن کاملEndozoochorous seed dispersal of plant species in semi-steppe rangelands
During last two decades studies on endozoochorous seed dispersal indicated that a large numbers of plant seeds are potentially dispersed and suceefully germinated via animal dung. However, very little is known about the relative importance of endozoochory in germination success of plant species in semi-steppe rangelands. In this paper we examined dung germinating seed content, seed deposition p...
متن کاملOverseas seed dispersal by migratory birds.
Long-distance dispersal (LDD) promotes the colonization of isolated and remote habitats, and thus it has been proposed as a mechanism for explaining the distributions of many species. Birds are key LDD vectors for many sessile organisms such as plants, yet LDD beyond local and regional scales has never been directly observed nor quantified. By sampling birds caught while in migratory flight by ...
