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

Ecology 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.

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

Ecology 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 ...

Contrasting Temporal Dynamics of Ostracod (Crustacea) Communities in Protected and Impacted Areas in a Brazilian Floodplain

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT Environmental integrity is vital for the long‐term preservation of freshwater biodiversity, which is currently among the most threatened on Earth due to anthropogenic pressures such as dam construction. The present study investigated the temporal responses of ostracod communities over 8 years (2017–2024) in the Upper Paraná River floodplain ...

Tree cavities as keystone structures in a semiarid region: Interspecific aggregations of anurans in the Brazilian Caatinga

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Tree cavities function as key microclimatic refuges for anurans in the semiarid Caatinga biome of northeastern Brazil, where we document previously unreported interspecific aggregations during the dry season. Observations from fauna rescue operations preceding vegetation clearance revealed eight distinct aggregations within cavities of two ...

A DNA sequence variation dataset across the understudied Andean poison frog genus Andinobates

Ecology, Volume 107, Issue 9, September 2026.
Abstract The poison frog family Dendrobatidae has radiated into over 300 species throughout the past 30 million years, occupying the majority of neotropical forest habitats. Species in this group have diversified widely in multiple aspects of their biology such as predator avoidance and parental care strategies, reproductive ecology, chemical ecology ...
