Global Dispersal of Free-Living Microbial Eukaryote Species

- 10 May 2002
The abundance of individuals in microbial species is so large that dispersal is rarely (if ever) restricted by geographical barriers. This “ubiquitous” dispersal requires an alternative view of the… Expand
Lipids of aquatic organisms as potential contributors to lacustrine sediments—II☆
Abstract The relationship between the lipid composition of organisms in the water column of an eutrophic lake and the lipid composition of underlying sediments, previously examined for n-alkanols and… Expand
Ecology and evolution in anoxic worlds
The structure of anaerobic communities, competition and syntrophy, and interactions with the oxic world are studied. Expand
Fluxes of methane and carbon dioxide from a small productive lake to the atmosphere
The fluxes of CH4 and CO2 to the atmosphere, and the relative contributions of ebullition and molecular diffusion, were determined for a small hypertrophic freshwater lake (Priest Pot, UK) over the… Expand
The Ubiquity of Small Species: Patterns of Local and Global Diversity
For small organisms, the relationship between species and area is flat, and a latitudinal diversity gradient is absent or weak, and these patterns are explained by some of the assumptions underlying the unified neutral community model. Expand
Respiration rates in heterotrophic, free-living protozoa
It is conceivable that protozoan species exist with lower maximum potential growth and metabolic rates than those predicted from cell volume and the equations derived from the available data, but the lack of information concerning the state of the cells studied prevents verification. Expand
Some rumen ciliates have endosymbiotic methanogens.

Most of the small ciliate protozoa, including Dasytricha ruminantium and Entodinium spp. living in the rumen of sheep, were found to have intracellular bacteria. These bacteria were not present in… Expand
Cosmopolitan metapopulations of free-living microbial eukaryotes.
It is shown that most organisms smaller than 1 mm occur worldwide wherever their required habitats are realised, and that the 1-10 mm size range accommodates a transition from cosmopolitan to regionally-restricted distribution. Expand
Protozoan control of bacterial abundances in freshwater.
It is suggested that bacterial abundances are regulated by substrate supply and HNAN grazing pressure and the structure and function of microbial food webs in freshwater environments may thus be similar to those suggested for marine systems. Expand
Freshwater protozoa: biodiversity and ecological function
The purpose of this article is to pull together various elements from current knowledge regarding the natural history of free-living protozoa in fresh waters. We define their functional role, set the… Expand
