Putting turbot on the map: environmental determinants, philopatry and high dispersal potential shed new light on population structure Instituut voor Landbouw-, Visserij- en Voedingsonderzoek
Research agrees that major declines in stock status are common, including many flatfish stocks. Despite the large human impact on fish stocks, both directly and indirectly, the source of degradation cannot be understood and successfully controlled, without understanding the behaviour of individuals and their interaction with these changes. In the past few years, many studies have suggested that several mechanisms may explain how population ...
Black soldier fly larvae as an alternative feed source and agro-waste disposal route : a life cycle perspective Universiteit Gent
Life cycle assessment (LCA) was applied to evaluate black soldier fly production using different diets, including typical Belgian agro-residues (Brussels sprout stems, endive roots and solid fraction pig manure). The LCA compared insect-based feed with soybean meal and fishmeal, and composting through insects versus conventional treatments. Underlying LCA data were derived through feeding experiments. To determine the sensitivity of the results, ...
Tree dispersal strategies in the littoral forest of Sainte Luce (SE-Madagascar) Koninklijke Maatschappij voor Dierkunde van Antwerpen
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 ...
Dispersal and predation of diaspores of Coula edulis Baill. in an evergreen forest of Gabon Koninklijke Maatschappij voor Dierkunde van Antwerpen
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 ...
Dispersal constraints for the conservation of the grassland herb Thymus pulegioides L. in a highly fragmented agricultural landscape Universiteit Gent KU Leuven Universiteit Antwerpen
Species-rich grassland communities are one of the most important habitats for biodiversity and of high conservation priority in Europe. Restoration actions are mainly focused on the improvement of abiotic conditions, such as nutrient depletion techniques, and are generally based on the assumption that the target community will re-establish at the restored site when the target species exist in the neighborhood. Information on the contemporary ...
More warm‐adapted species in soil seed banks than in herb layer plant communities across Europe Universiteit Gent Instituut voor Natuur- en Bosonderzoek KU Leuven
Responses to climate change have often been found to lag behind the rate of warming that has occurred. In addition to dispersal limitation potentially restricting spread at leading range margins, the persistence of species in new and unsuitable conditions is thought to be responsible for apparent time-lags. Soil seed banks can allow plant communities to temporarily buffer unsuitable environmental conditions, but their potential to slow responses ...
Food stress during juvenile and maternal development shapes natal and breeding dispersal in a spider Universiteit Gent
Can the seed bank be used for ecological restoration? A quantative overview of seed gank characteristics in European Communities? KU Leuven
QUESTION: Can seeds in the seed bank be considered as a potential source of material for the restoration of European plant communities including forest, marsh, grassland and heathland? METHODS: This study reviews seed bank studies (1990–2006) to determine if they provide useful and reliable results to predict restoration success. We formally selected 102 seed bank studies and analyzed differences between four plant community types in several ...
Impact of avian frugivores on dispersal and recruitment of the invasive Prunus serotina in an agricultural landscape KU Leuven Universiteit Gent
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 ...
