Inventory reveals non-native species and variation in spatial-temporal dynamics of fish community in a Brazilian protected area [PDF]
Brazilian Journal of Biology, 2023 The increase in the number of Brazilian protected areas has been progressive and, although it is essential for the conservation of biodiversity, it is important to monitor and properly manage these areas, as they present several cases of biological ...

Journal of Fish Biology, EarlyView.Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

High Melt Fraction Induced by the Dehydration Melting Near the 410‐km Discontinuity
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract The water‐rich mantle transition zone, coupled with the low water storage capacity of the upper mantle, suggests that dehydration melting occurs just above the mantle transition zone near the 410‐km discontinuity. However, the melt fraction produced by the dehydration melting process remains poorly constrained.

Trophic Redundancy and the Hidden Dietary Overlap Between Native and Invasive Stream Fishes
Ecology of Freshwater Fish, Volume 35, Issue 3, July 2026.ABSTRACT Biological invasions introduce non‐native species into natural ecosystems, often reshaping localcommunities and altering trophic interactions. In freshwater environments, such invasions can intensify resource use and threaten native fish diversity.
