ABSTRACT Beta diversity is an important descriptor of community structuring and it plays a crucial role for understanding the patterns and processes shaping biodiversity at multiple spatial extents. We investigated the influence of local, spatial, landscape factors and niche characteristics on fish beta diversity along the Acre River in Acre, Brazil ...

ABSTRACT The endemic catfish Steindachneridion melanodermatum from the Iguaçu River basin, southern Brazil, is one of the most threatened pimelodid species. Comprehension of its genetic structure is imperative to the formulation of long‐term efficacious conservation strategies. A genetic analysis was conducted on three populations from the lower Iguaçu

Karyotypes of two species of the genus Pimelodus (Siluriformes, Pimelodidae).
A cytogenetic study was conducted on two species of the genus Pimelodus that were collected from the Piquiri river, Paraná, Brazil: Pimelodus paranaensis and Pimelodus heraldoi. Both had a diploid number of 2n=56 chromosomes and a fundamental number (FN) of 104. In P.

CYTOGENETIC STUDIES ON FISHES OF THE FAMILY PIMELODIDAE (SILUROIDEI)
Four fish species of the family Pimelodidae were analyzed. Bergiaria westermani and two different Pimelodus species have the same diploid chromosome number (2n - 56).

Use of probiotics in the catfish Sorubim cuspicaudus larviculture
Sorubim cuspicaudus, a migratory catfish distributed in the Magdalena, Sinú, and Catatumbo river basins, is categorized as vulnerable to extinction. Production of fingerlings in controlled environments stands as a strategic conservation approach, and ...

This research approaches the interaction between frugivorous fish and the flooded forests in the central Amazon. We evaluated the fruit consumption by fish and the seed dispersal potential along the flood gradient. We tested the hypothesis that the role of fish as seed dispersers varies between low várzea (LV) and high várzea (HV) forests.

Cytogenetic studies on fishes of the family pimelodidae (siluroidei) [PDF]
Four fish species of the family Pimelodidae were analyzed. Bergiaria westermani and two different Pimelodus species have the same diploid chromosome number (2n - 56). Despite some differences in chromosome structure, these species are highly similar in karyotype and differ from Pimelodella sp., which presents a reduction in chromosome number to 2n = 46.

The viability of post-thaw fish oocytes can be affected by different stages of the freezing process, such as cryoprotectant toxicity, cold sensitivity, freezing curves and thawing. Therefore, these steps need to be investigated for the development of a protocol.
