Aplicação de técnica de geoprocessamento em áreas degradadas de mata ciliar e sua correlação com qualidade da água numa subbacia hidrográfica
(2011-09-12)
Studying the physical environment of a watershed is the basic condition for a successful planning of the riparian forest preservation, and for water production and conservation. The aims of the present study were to analyze ...

Genetic isolation among mountains but not between stream types in a tropical high-altitude mayfly
(BLACKWELL PUBLISHING LTD, 2016-05-01)
Glaciers that directly feed high-altitude streams create unique environmental conditions that contribute substantially to regional-scale lotic habitat diversity and biodiversity, including intra-specific genetic diversity ...
Diet of invertebrates sampled in leaf-bags incubated in a tropical headwater stream
(Sociedade Brasileira de Zoologia, 2009-12-01)
The diet of macroinvertebrates sampled in leaf-bags incubated in a tropical stream was analyzed on a spatial scale (one forested and one deforested area) and on a temporal scale (dry and rainy seasons). The macroinvertebrates ...

A decade later: the effects of land use changes in biodiversity patterns of stream fish assemblages from a tropical agroecosystem
(Universidade Estadual Paulista (Unesp), 2017-04-28)
Mudanças ambientais associadas a conversão da vegetação nativa em agroecossistemas são consideradas um poderoso motor de homogeneização da ictiofauna no Antropoceno. Assim, é primordial entender como subsequentes alterações ...
Ordinal pattern and statistical complexity analysis of daily stream flow time series
(Springer, 2013-06)
When calculating the Bandt and Pompe ordinal pattern distribution from given time series at depth D, some of the D! patterns might not appear. This could be a pure finite size effect (missing patterns) or due to dynamical ...
Climate change and alpine stream biology: progress, challenges, and opportunities for the future
(BLACKWELL PUBLISHING LTD, 2017-11-01)
In alpine regions worldwide, climate change is dramatically altering ecosystems and affecting biodiversity in many ways. For streams, receding alpine glaciers and snowfields, paired with altered precipitation regimes, are ...
