Ecology and Zoogeography of Parasites
Parasitism is a ubiquitous phenomenon that is probably as old as heterotrophic organisms themselves. It is one of the major types of symbiotic relationship between organisms of different species. The development of the biological sciences brought about a broader definition of parasitism. By the end of the nineteenth century, it was known that parasites thrive at the expense of their hosts and u...
متن کاملAnnotated zoogeography of non-marine Tardigrada. Part I: Central America.
Dividing the world into nine regions, this first paper describes literature records of the limno-terrestrial tardigrades (Tardigrada) reported from Central America. Updating previously published species lists we have revised the taxonomy and provided additional habitat, geographic co-ordinates, and biogeographic comments. It is hoped this work will serve as a reference point and background for ...
متن کاملParasites and marine invasions.
Introduced marine species are a major environmental and economic problem. The rate of these biological invasions has substantially increased in recent years due to the globalization of the world's economies. The damage caused by invasive species is often a result of the higher densities and larger sizes they attain compared to where they are native. A prominent hypothesis explaining the success...
متن کاملZoogeography of Antillean Bats
Analysis of the bat fauna of the Antillean Islands suggest that the most probable source of invnsion of the islands by bats is by overwaLer dispersal. The bat fauDa of ·the Greater Antilles is unique, a percentage of endemism on each island being over 50 percent except for the Virgin Islands which has 33 percent endemics. The richest bat fauna in the Antilles is on Cuba (32 species) followed by...
متن کاملGreater diversification of freshwater than marine parasites of fish.
The species richness of freshwater environments is disproportionately high compared with that of the oceans, given their respective sizes. If diversification rates are higher in freshwaters because they are isolated and heterogeneous, this should apply to parasites as well. Using 14 large datasets comprising 677 species of freshwater and marine fish, the hypothesis that freshwater parasites exp...
