Use of DNA barcode in the identification of fish eggs in tributaries of the Paranapanema River basin. [PDF]

Genet Mol Biol, 2020
Fish eggs are often excluded from identification analysis since at this stage of development there are few morphological characters. The correct identification of eggs can provide important information about spawning areas of species. The current work aimed to identify fish eggs in the Tibagi and Cinzas Rivers using the DNA barcode to obtain ...

Fish fauna from the Paranapanema River basin, Brazil [PDF]

Biota Neotropica, 2020
Abstract: The Paranapanema River is an important, extensively explored tributary of the Upper Paraná River basin. The fish fauna of the Paranapanema River has been investigated since the 1990s; however, no study has characterized the richness of fish species throughout the basin, including the main channel of the river, marginal lagoons, its ...

Cephalic Musculature of the Pacman Catfish Lophiosilurus alexandri Steindachner, 1876 (Siluriformes, Pseudopimelodidae). [PDF]

J Morphol
The head of the Pacman catfish (Lophiosilurus alexandri [L. alexandri]) is strongly depressed, broad, and with a large mouth, roughly resembling those of Lophius piscatorius and Chaca bankanensis. Also, they are bottom dwellers and have ambush behavior for fish predation.

ICHTHYOFAUNA OF TRIBUTARY STREAMS OF THE CINZAS RIVER BASIN, PARANAPANEMA RIVER, BRAZIL

Oecologia Australis, 2021
Streams are environments that are very affected by human activities such as pollution, deforestation of riparian forests and introduction of exotic species. In this context, it is important to know its biodiversity for monitoring and conservation. The present study inventoried the fish fauna of three tributary streams of the Jacarezinho River (Cinzas ...

Machine learning models accurately predict clades of proteocephalidean tapeworms (Onchoproteocephalidea) based on host and biogeographical data. [PDF]

Cladistics
Abstract Proteocephalids are a cosmopolitan and diverse group of tapeworms (Cestoda) that have colonized vertebrate hosts in freshwater and terrestrial environments. Despite the ubiquity of the group, key macroevolutionary processes that have driven the group's evolution have yet to be identified.

Knowing biodiversity: Fishes from the Guareí River basin, a tributary of the Jurumirim reservoir, Paranapanema River, Brazil [PDF]

Biota Neotropica, 2020
Abstract: The Guareí River is a tributary of the Paranapanema River (Brazil), located in the upper portion of the Jurumirim Reservoir. Fish fauna studies in this watershed began in the 2000s, but they were restricted to a few waterbodies. This work conducted a broad survey of the fish fauna in tributary streams and the main channel of the Guareí River.

Headwater stream fish fauna from the Upper Paranapanema River basin [PDF]

Biota Neotropica, 2016
Abstract The Paraná River basin has about 600 fish species. In the Upper Paraná, 310 fish species were recorded, with 52 species were registered in the streams and headwaters of the Paranapanema River. The aim of this study was to characterize the stream fish communities in the Upper Paranapanema River basin.

Fish defaunation in reservoirs of the Lower Paranapanema River basin, Brazil

Biota Neotropica, 2022
Abstract Until now no study has used a defaunation index to quantify the decline of Neotropical freshwater fishes in environments fragmented by dams and reservoirs. So, we applied this index to 143 native fish in five reservoirs in the Lower Paranapanema River, that is situated in one of the Brazilian aquatic environments most impacted by anthropic ...

Overlooked Bird Extinctions in Semideciduous Atlantic Forests. [PDF]

Ecol Evol
Due to near total deforestation in much of the Brazilian state of São Paulo in the early 20th century, essentially all non‐coastal and not montane forest fragments today are regenerated. Before deforestation, most Atlantic Forest endemic bird species were found throughout the state, as demonstrated by museum specimens and the previous literature ...
