The spatial distribution of 138 Dorylaimid and Mononchid species collected in a natural area from the Southeast Iberian Peninsula was studied. A chorological classification was used to examine distribution patterns shared by groups of species. Eighty species were classified into 14 collective and 16 individual chorotypes. The geographical projections of several collective chorotypes are illustr...

The aim of this study is to identify significant biotic regions (groups of areas with similar biotas) and biotic elements (groups of taxa with similar distributions) for the marsupial fauna in a part of northern South America using physiographical areas as Operational Geographical Units (OGUs). We considered Venezuela a good model to elucidate this issue because of its high diversity in landsca...

A biogeographical classification of reptiles in the Riff region (northern Morocco, Africa) was carried out to look for shared distribution patterns, here termed chorotypes. Baroni-Urbani & Buser’s similarity index was applied to the presence/absence data of reptiles in 10#10 km UTM (Universal Transverse Mercator) squares, and then UPGMA (Unweighted Pair-Group Method using arithmetic average) wa...

We analyzed plants and their traits in dolines, which are characteristic enclosed terrain depressions on carbonate (karst) plateaus. These landforms range from a few meters to over 100 m diameter, depth generally varying tens of meters. A pronounced ecological gradient can be found the bottom top, starting humid, cool shaded bottoms sunny, dry warm slopes tops. sampled dolines various depths di...

A review of Staphylinidae known from peat bogs of Belarus is presented with data on their distribution at various sites. The staphylinid fauna, as reported here, includes 66 species, 33 genera, and 10 subfamilies. The results showed a low species richness of rove beetles and a high occurrence of a small number of species. The regional zoogeography and composition of rove beetles in the Belarusi...

abstract. vegetation of each region is one of the most important phenomena of nature and is the best guide to judge about the ecological sciences of that region because the plants are resistant organisms that have endured the long term conditions of all kinds of environmental conditions for a long period of time and have adapted with environmental stresses. therefore floristical investigation o...
