Fragmentation by Dams and Habitat Quality Affect Body Condition of a Small Characid in a Neotropical System

open access: yesEcology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT The structure of stream networks naturally fragments freshwater habitats, but this complexity is increasingly intensified by dams and reservoirs. How anthropogenic fragmentation interacts with natural isolation gradients to affect fish populations remains poorly understood.

Trophic levels of fish species of commercial importance in the Colombian Caribbean

open access: yesRevista de Biología Tropical, 2011
Ecological studies on commercial important fish species are of great value to support resource management issues. This study calculated trophic levels of those Colombian Caribbean fish species whose diet has been locally described.

Beyond Occurrence: Evidence Gaps for Non‐Native Freshwater Fishes in Brazilian Drylands

open access: yesEcology of Freshwater Fish, Volume 35, Issue 4, October 2026.
ABSTRACT Non‐native freshwater fishes are widely reported in inland waters, but occurrence records are often interpreted together with stronger evidence of establishment, reproduction, spread, pathways and impacts. This can overstate what published records support, especially in regions where reservoirs, river‐basin transfers and artificial ...

External structures at the nest‐site predict asymmetric architecture of nests in a mud‐building bird

open access: yesIbis, Volume 168, Issue 4, Page 1696-1703, October 2026.
In the animal kingdom, nests are essential structures and textbook examples of extended phenotypes. However, the relationship between builders, nest traits and the nest‐site remains poorly understood. We indirectly examine whether structures in the nest‐site influence nest‐building behaviour, specifically focusing on their effect on nest architecture ...
