Abstract
ABSTRACT The benthic fauna in northern Patagonian streams is characterized by presence of water quality indicator species. The aim of the present study was characterized the benthic communities in streams associated to sites with presence of Nothofagus forests and with human intervention without Nothofagus forests using null models in ecology, unified neutral theory of biodiversity (UNTB) and unweighted pair group method with arithmetic mean (UPGMA). The results of species co-occurrence null model revealed that species associations are random, whereas the results of niche overlap null models revealed the presence of niche overlap. The UNTB results revealed low species number. The results of UPGMA revealed that species composition is specific for each site existing marked differences. The exposed results agree with results observed for central and northern Patagonian Chilean rivers, where the species composition is variable in according to surrounding basin properties and seasonal conditions.
期刊介绍：
The journal Iheringia, Série Zoologia, edited by the “Museu de Ciências Naturais” of the “Fundação Zoobotânica do Rio Grande do Sul”, publishes original research findings in zoology with emphasis on taxonomy, systematics, morphology, natural history, and community or population ecology of species from current Neotropical fauna. Scientific notes will not be accepted for publication. Species lists without a taxonomic approach, or that are not the result of studies on the ecology or natural history of communities will not normally be accepted. The same applies to identification keys of groups of taxa defined by political boundaries. Authors wishing to inquire about the scope of the journal or the suitability of a particular topic are encouraged to contact the Editorial Board prior to submission. Furthermore, articles with a main focus on agronomy, veterinary, zootechny or other areas involving applied zoology will not be accepted.
Its abbreviated title is Iheringia, Sér. Zool., which should be used in bibliographies, footnotes and bibliographical references and strips.
