Cavernosa kapitiana (Bacillariophyceae) : Biogeography and morphology of the different life cycle stages Plantentuin Meise / Agentschap Plantentuin Meise Universiteit Antwerpen
The monospecific diatom genus Cavernosa is known from only two locations: Kapiti Island off the west coast of New Zealand and Ile de la Possession, Crozet Archipelago, in the southern Indian Ocean. Cavernosa kapitiana Stidolph is a chain-forming diatom with cylindrical frustules having an elongated valve mantle. We provide a description of the different life-cycle stages (normal frustules, globular initial cells, bell-shaped initial cells, first ...
Biogeography and ecology of freshwater diatoms in Subantarctica: A review Plantentuin Meise / Agentschap Plantentuin Meise
Subantarctica is situated between the Antarctic and the Subtropical Convergence and consists of the islands in the southern Atlantic, Indian and Pacific Oceans. Diatoms are an important component of all Subantarctic aquatic, moss and soil habitats. Taxonomic studies reveal a high diversity and species richness in both the present-day and the fossil diatom flora. Planktonic diatoms are almost completely absent. A similarity analysis of the diatom ...
Diversity, ecology and biogeography of the freshwater diatom communities from Ulu Peninsula (James Ross Island, NE Antarctic Peninsula) Plantentuin Meise / Agentschap Plantentuin Meise Universiteit Antwerpen
The diversity, ecology and biogeography of diatoms in lakes, seepage areas and streams on the Ulu Peninsula, a large ice-free area in the northern part of James Ross Island (Weddell Sea), were studied. A diverse diatom flora of 123 taxa was observed, dominated by several Nitzschia taxa, Psammothidium papilio, Eolimna jamesrossensis, Fragilaria capucina and Fistulifera saprophila. The results from the similarity and diversity analysis suggest ...
Partitioning the variation in African vertebrate distributions into environmental and spatial components – exploring the link between ecology and biogeography Vrije Universiteit Brussel KU Leuven
There has been a proliferation of studies aimed at predicting the distributions of species from environmental variables despite evidence that spatial interpolation or spatially-constrained mechanistic models have comparable explanatory power. Moreover, the processes behind environmental and spatial correlations - and their interactions - remain elusive. Here, we examined geographic patterns in the amount of variation explained by environmental ...

Phylogeny, diversity and biogeography of Neotropical sipo snakes (Serpentes: Colubrinae: Chironius) Vrije Universiteit Brussel
Neotropical sipo snakes (Chironius) are large diurnal snakes with a long tail and big eyes that differ from other Neotropical snakes in having 10 or 12 dorsal scale rows at midbody. The 22 currently recognized species occur from Central America south to Uruguay and northeastern Argentina. Based on the largest geographical sampling to date including ∼90% of all species, we analyzed one nuclear and three mitochondrial genes using phylogenetic ...
Biogeography of the Lost World (Pantepui region, northeastern South America): Insights from bryophytes Vrije Universiteit Brussel
The 'Pantepui' region of northern South America comprises about 50 topographic islands above a lowland/upland rainforest matrix and constitutes a model of choice for testing island theory hypotheses in a continental setting. Although the Guiana Highlands are considered as the second most important center of endemism in the Neotropics for hepatics, the 10% endemism rates at the species level in liverworts, and probably even less in mosses, pale ...
