Conservation threats and future prospects for the freshwater fishes of Ecuador: A hotspot of Neotropical fish diversity

open access: yesJournal of Fish Biology, Volume 99, Issue 4, Page 1158-1189, October 2021., 2021
ABSTRACT Freshwater fish communities in Ecuador exhibit some of the highest levels of diversity and endemism in the Neotropics. Unfortunately, aquatic ecosystems in the country are under serious threat and conditions are deteriorating. In 2018–19, the government of Ecuador sponsored a series of workshops to examine the conservation status of Ecuador's ...

Primordial germ cells identification and traceability during the initial development of the Siluriformes fish Pseudopimelodus mangurus.

open access: yesFish Physiology and Biochemistry, 2022
Abstract Primordial germ cells (PGCs) are responsible for the generation of all germ cells, and therefore, they are essential targets to be used as a tool for the production of germline chimera. The labeling and route of PGCs were evaluated during the initial embryonic development of Pseudopimelodus mangurus, using whole-mount in situ ...

Cytogenetic Analyses of Pseudopimelodus mangurus (Teleostei: Siluriformes: Pseudopimelodidae)

open access: yesCYTOLOGIA, 2004
The cytogenetic analyses showed that Pseudopimelodus mangurus has a diploid number of 2n=54 chromosomes (6M, 26SM, 12ST and 10A), single Ag-NORs on the short arm of a middle-sized ST pair, identified as pair 19, and a very small amount of C-band positive segments in two chromosome pairs. The Ag-NORs are C-band positive.
