Why mountains matter for biodiversity

Mountains are arguably Earth's most striking features. They play a major role in determining global and regional climates, are the source of most rivers, act as cradles, barriers and bridges for species, and are crucial for the survival and sustainability of many human societies. The complexity of mountains is tightly associated with high biodiversity, but the processes underlying this association

What's on your boots : An investigation into the role we play in protist dispersal

D. M. Wilkinson (2010, Journal of Biogeography, 37, 393-397) suggested that anthropogenic dispersal is an understudied and potentially important factor in terrestrial protist biogeography. We investigated human footwear as a potential vector of dictyostelids, a diverse group of amoebae that includes both geographically restricted and cosmopolitan species. Eighteen pairs of boots were examined and

Diversity of dictyostelid social amoebae in high latitude habitats of Northern Sweden

The dictyostelid social amoebae (Dictyostelia) occur in terrestrial habitats worldwide. It has been observed previously that their diversity decreases with increasing latitude and altitude. Here we look at dictyostelid diversity in the high latitude habitats of Northern Sweden. Dictyostelids were recovered from soil samples using traditional plating methods and then identified using morphological

Five new species of dictyostelid social amoebae (Amoebozoa) from Thailand

Background: Dictyostelid cellular slime molds (dictyostelids) are common inhabitants of the soil and leaf litter layer of fields and forests, along with animal dung, where they feed mostly on bacteria. However, reports on the species diversity of dictyostelids in South Asia, particularly Thailand, are limited. The research reported in this paper was carried out to increase our knowledge of the spe

Additional new species suggest high dictyostelid diversity on Madagascar

Dictyostelids are a monophyletic group of sorocarp-forming social amoebae in the major eukaryotic division Amoebozoa. Members of this taxon, which is made up of almost 200 described species, are common in terrestrial soils globally. Still, the alpha diversity is not well known in many areas, and new species are frequently recovered. The highest species richness is found in the tropics. Here, five
