Leaf litter breakdown and benthic invertebrate colonization affected by seasonal drought in headwater lotic systems of Andean Patagonia
(Springer, 2015-11)
We aimed to establish the effect of seasonal drought on leaf litter breakdown and invertebrate communities. Differences in breakdown rates of Nothofagus pumilio were experimentally compared using the litter bag method ...
Effect of leaf decomposition stage and water temperature on fragmentation activity of a shredder invertebrate species in lotic ecosystems
(Fundação Zoobotânica do Rio Grande do Sul, 2017)
A atratividade de um determinado detrito foliar pelos invertebrados depende da composição química, estrutura física, estágio de colonização microbiana e nível de degradação do detrito. Além da qualidade do detrito foliar, ...
Looking for a place: How are tadpoles distributed within tropical ponds and streams?
(2018-05-09)
Microhabitat use by tadpoles has been little documented, especially for neotropical anuran species. Here we describe microhabitat use by tadpoles in two different aquatic systems, lentic and lotic, in the Atlantic Rainforest. ...
Population biology of Astyanax lacustris (Pisces, Characiformes) in a Neotropical reservoir and its tributaries
(Academia Brasileira de Ciências, 2021-07-07)
The aging process of reservoirs has been extensively investigated; however, little is known about how fish populations are adjusted after many years of impoundment. Thus, this study aimed to compare the diet, length-weight ...
Método para la cría en laboratorio de Chironomidae (Díptera) de ambientes lóticosLaboratory Rearing Methodology for Chironomidae (Diptera) of Lotic Environments
(Universidad Nacional de Colombia, 2016-04)
La taxonomía de Chironomidae se apoya fuertemente en la integración de las características morfológicas de todas las fases del ciclode vida, las cuales se pueden obtener mediante la cría en laboratorio. Este estudio ...
A comparative study of Odonata (Insecta) in aquatic ecosystems with distinct characteristics
(2013)
The objective of this study was to compare the richness and density of Odonata larvae in four distinct environments: lotic with large pollutant loads, lotic with small pollutant loads, lentic disconnected from a river and ...
Changes in the bacterial community composition of different habitats along a polluted river (Suquía River, Cordoba, Argentina)
(Asociación Argentina de Ecología, 2017-03)
The objective of the present study was to investigate the influence of environmental conditions on the bacterial community composition in water, sediment and riparian soil during different water flow periods. For this ...
Diversity of Ephemeroptera (Insecta) of the Serra da Mantiqueira and Serra do Mar, southeastern Brazil
(SOC BRASILEIRA ENTOMOLOGIACURITIBA, 2012)
Diversity of Ephemeroptera (Insecta) of the Serra da Mantiqueira and Serra do Mar, southeastern Brazil. The aim of this study was to inventory the mayfly fauna, based on nymphal and alate stages, in Serra da Mantiqueira ...
Environmental factors associated with heterotrophic nitrogen-fixing bacteria in water, sediment, and riparian soil of Suquía River
(Elsevier Gmbh, 2014-07)
In this study we investigated the environmental factors associated with biological nitrogen (N) fixation (BNF) in water, sediments, and riparian soil along a polluted river (Suquía River of Córdoba, Argentina). Here, we ...
The effect of the land use on phytoplankton assemblages of a Cerrado stream (Brazil)
(Associação Brasileira de Limnologia, 2012-03-01)
OBJETIVO: Nosso objetivo foi investigar se o uso do solo do ambiente terrestre adjacente influencia a estrutura das assembleias fitoplanctônicas (composição, riqueza, diversidade e abundância) e biomassa (clorofila-a) em ...
