Impact of avian frugivores on dispersal and recruitment of the invasive Prunus serotina in an agricultural landscape KU Leuven Ghent University
Although seed dispersal is considered to be a key process determining the spatial structure and spread of non-native plant populations, few studies have explicitly addressed the link between dispersal vector behaviour, seed distribution and seedling recruitment to gain insight into the process of exotic species invasion within a fragmented landscape context. The present study analyses the relationship between avian frugivory and spatial patterns ...
Diurnal frugivores on the Bromeliaceae Aechmea depressa LB Sm. from Northeastern Brazil: the prominent role taken by a small forest primate Royal Zoological Society of Antwerp
Little is lcnown about frugivory of epiphytes. We investigated diurnal frugivores consuming Aechmea depressa, an endemic species from Southern Bahia, Brazil, through 67 hours of observation on three fruiting individuals. Infructescences were visited for 2% of the time and only by golden-headed lion tamarins (GHLTs; Leontopithecus chrysomelas). Aechmea depressa invests on physical defense to retain fruits for prolonged periods, however, GIALTs ...
Complementary seed dispersal by three avian frugivores in a fragmented Afromontane forest Ghent University
QuestionsTo what extent does species-specific variation in gut passage time (GPT), habitat use and mobility of three key avian frugivores synergistically affect the distribution of Xymalos monospora seeds within and among isolated forest fragments?LocationThree fragments of a severely fragmented cloud forest, Taita Hills, southeast Kenya.MethodsWe experimentally determined GPTs of X. monospora seeds and recorded movements and habitat use by ...
Indigenous cloud forest fragmentation reduces seed dispersal by avian frugivores in an East-African biodiversity hotspot Ghent University

Tree dispersal strategies in the littoral forest of Sainte Luce (SE-Madagascar) Royal Zoological Society of Antwerp
Zoochory is the most common mode of seed dispersal for the majority of plant species in the tropics. Based on the assumption of tight plant-animal interactions several hypotheses have been developed to investigate the origin of life history traits of plant diaspores and their dispersers, such as species-specific co-evolution, the low/high investment model (low investment in single fruits but massive fruiting to attract many different frugivores ...
An intersite comparison on fruit characteristics in Madagascar: Evidence for selection pressure through abiotic constraints rather than through co-evolution Royal Zoological Society of Antwerp
Fruit and seed characteristics are compared between a dry deciduous forest in the west and a humid littoral forest in the south-east of Madagascar to discriminate between the role of abiotic factors (humidity, climate, soil characteristics) and frugivorous vertebrates for the evolution of morphological and biochemical fruit characteristics. The sites differed in abiotic conditions but contain very similar communities of frugivorous vertebrates. ...
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 ...
