Threshold responses of floating meadow fish communities to floodplain forest cover in the lower Amazon River

Conservation Biology, EarlyView.
Abstract Forest cover is positively associated with fish biomass and fisheries yield in the Amazon River floodplain, and many species enter flooded forests to feed, spawn, or seek refuge from predation. Floating macrophyte beds, known as floating meadows, in Amazon floodplains support high fish diversity and serve as nursery habitat for many fishes of ...

New insights into the putative XX/XY sex chromosomal system in blue‐eyed red‐fin pleco Hypostomus soniae (Siluriformes, Loricariidae)

Journal of Fish Biology, EarlyView.
Abstract Blue‐eyed red‐fin pleco Hypostomus soniae (family Loricariidae) presented a putative sex system XX/XY in early stage. Aiming to explore the inter‐populational karyotypic variation and proposed emergence of the XX/XY system, we studied 13 H. soniae individuals (6 males, 7 females) from the Tapajós River.

Effects of Land Use and Environmental Characteristics on Condition Factor and Reproductive Aspects of Serrapinnus notomelas (Brazil)

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.
ABSTRACT Changes in land use and land cover severely impact the ecological structure of aquatic ecosystems and can lead to losses in fish populations. To further examine the cause and effect, the present study aimed to evaluate (1) differences in land use and cover among subbasins of the Vacaria, Brilhante, Dourados and Lower Ivinhema Rivers, (2 ...
