(Universidade Federal da BahiaEcologia e BiomonitoramentoUFBAbrasil, 2014-02-06)
Longitudinal variation in the composition of the benthic macroinvertebrate fauna of a typical North coast Jamaican river
(Universidad de Costa Rica, 2012)
Land-use effects on structural and functional composition of benthic and leaf-associated macroinvertebrates in four Andean streams
(2018)
The replacement of native forests by pastures takes place widely in the Andes. The effects of such land-use change on aquatic assemblages are poorly understood. We conducted a comparative analysis of the effects of forest ...
A study of flow dynamics and implications for benthic fauna in a meander bend of a lowland river
(Int Assoc Hydraulic Research, 2015-07)
Channel curvature and riffle-pool bathymetry in meandering streams control complex hydrodynamic and morphodynamic processes. This study investigates how spatial and temporal heterogeneities in flow hydraulics influence ...
Genetic structure and demographic inference of the regular sea urchin Sterechinus neumayeri (Meissner, 1900) in the Southern Ocean: The role of the last glaciation
(Public Library Science, 2018-06)
One of the most relevant characteristics of the extant Southern Ocean fauna is its resiliency to survive glacial processes of the Quaternary. These climatic events produced catastrophic habitat reductions and forced some ...
Benthic invertebrate assemblage in Samborombón River (Argentina, S. America), a brackish plain river
(Springer, 2008-09-14)
The spatial and temporal differences in the structure and composition of benthic invertebrates were studied at three sites of the Samborombón River, which is an important tributary of the Río de la Plata Estuary (Argentina), ...
The impact of significant imput of fine sediment on benthic fauna at tributary junctions: a case study of the Bermejo-Paraguay River confluence, Argentina
(Wiley, 2014-06)
This study examines the morphological features, suspended sediment inputs and hydraulic conditions within a large river in association with ecological patterns before and after a tributary confluence. In order to examine ...
How seasonality and anthropogenic impacts can modulate the structure of aquatic benthic invertebrate assemblages
(2017-04-01)
We studied a benthic invertebrate assemblage of a stream that passes through pristine, rural, suburban and urban areas of a municipality located in southeastern Brazil to investigate a possible relationship between this ...
