Species richness and functional structure of fish assemblages in three freshwater habitats: effects of environmental factors and management
(Wiley-Blackwell, 2019-08-12)
In this study, the inverted trophic hypothesis was tested in the freshwater fish communities of a reservoir. The distribution of fish species in three freshwater habitats in the Jurumirim Reservoir, Brazil, was examined ...
Reconciling more than 150 years of taxonomic confusion: The true identity of Moenkhausia lepidura, with a key to the species of the M. lepidura group (Characiformes: Characidae)
(2016-05-03)
Moenkhausia lepidura (Kner) is redescribed based on the examination of the type and other specimens from several localities of the Amazon and Orinoco basins. The species is readly diagnosed from congeners by a combination ...
Can fishways restore river connectivity? A case study using β diversity as a method of assessmentPassagens para peixes podem restaurar a conectividade fluvial? Um estudo de caso usando diversidade β como método de avaliação
(2018-01-01)
Aim: β diversity was used as an indicator to test the hypothesis that a fishway can increase river connectivity, as a reduction in the value of this metric indicates greater similarity among fish assemblages. Methods: ...
A novel method to obtain accurate length estimates of carnivorous reef fishes from a single video camera
(Sociedade Brasileira de Ictiologia, 2015-05)
In the last years, technological advances enhanced the utilization of baited underwater video (BUV) to monitor the diversity, abundance, and size composition of fish assemblages. However, attempts to use static single-camera ...
Effects of area and available energy on fish assemblages of tropical streams
(2017-01-01)
A central issue in fish community ecology is to understand how the size of the drainage area and the available energy influence fish species diversity and their spatial distribution. In the present study, we tested whether ...
Moenkhausia andrica (Characiformes: Characidae): a new species from the rio Tapajós basin, Brazil, with minute fin hooklets in females
(2021-10-01)
In this study, a new species of Moenkhausia is described from the upper rio Juruena, rio Tapajós basin, Brazil. It is distinguished from all congeners by the presence of minute bony hooks in all fins of both mature females ...
Assessment of biases in the estimation of tag shedding rates through a mark-resight experiment
(Elsevier, 2013-01)
Several flexible methods for estimating tag loss rates through mark-resight data have been developed recently. They allow evaluation of different tag shedding modalities and relax the usual assumption of independence ...
On the relationship between squid and the environment: artisanal jigging for Loligo plei at Sao Sebastiao Island (24 degrees S), southeastern Brazil
(OXFORD UNIV PRESS, 2010)
The squid Loligo plei concentrates in the southeastern Brazil Bight, where it has traditionally supported small-scale fisheries around Sao Sebastiao Island (SSI). Sea surface temperature (SST), chlorophyll-a (Chl a), ...
Combined phylogeny of ray-finned fishes (Actinopterygii) and the use of morphological characters in large-scale analyses
(Wiley Blackwell Publishing, Inc, 2017-08)
This study evaluates the phylogeny of ray-finned fishes (Actinopterygii) combining most available information (44 markers from nuclear and mitochondrial DNA and 274 morphological characters). The molecular partition of the ...
