and the distribution of the main species assemblages within the investigated area (10-800-m bathymetric range). Multivariate analysis of MEDITS survey catch data showed a strong relationship between fish assemblages and depth, while the influence of depth was lower with respect to cephalopod and especially crustacean

and centres of 24 nearby natural bogs in plots similar in size to these remnants. Using similarity analysis and ordination techniques, we found that plant species assemblages in rem-nants of mined bogs differ from those near the margins of natural bogs, and that certain species are associated with the centre

The Bristol Bay watershed supports abundant populations of all five species of Pacific salmon found in North America (sockeye, Chinook, chum, coho, and pink), including nearly half of the world’s commercial sockeye salmon harvest. This abundance results from and, in turn, contributes to the healthy

Abstract. We revise the species-level taxonomy of the Crematogaster (Crematogaster) degeeri-species-assemblage, a group of related ants occuring in Madagascar and the wider Malagasy region, and further provide an identifi cation key to all species-groups of the genus Crematogaster in this region

developed a null model to test the size-distance regression, and assessed the effects of competition and facilitation (including interspecific interactions, intraspecific interactions and overall species interactions) on each adult tree species assemblage [diameter at breast height (dbh) $5 cm] across two

Abstract: Species assemblage comparison is important in many ecological studies. In this paper, we develop a novel test for comparing species assemblages when abundance data from multiple quadrats are available. The test is based on the zero-inflated Poisson mixture model which we introduce

scales. Location We studied amphibian and reptile assemblages (forty-five species) occurring on 107 islands among four archipelagoes (Lake Erie, St Lawrence, Georgian Bay, Apostle) in the Laurentian Great Lakes of North America. The entire basin was recolonized in the post-Pleistocene by amphibians

ABSTRACT. Aquatic habitats are threatened by human activities in Turkey. These threats can lead to changes in ecological condi-tions and community composition of ostracod species. Overall, reduction in habitat quality may increase the number of tolerant (e.g., generalist) species in relation

Background: It has been suggested that statistical parsimony network analysis could be used to get an indication of species represented in a set of nucleotide data, and the approach has been used to discuss species boundaries in some taxa. Methodology/Principal Findings: Based on 635 base pairs

remnant native vegetation and a third were degraded and not revegetated. In the local survey the results of the landscape survey were tested by sampling sites within a small area using the same methods but including pine plantations as an untreated site. Here we report on density and species composition
