Genomic Evaluation in Nellore Cattle for Reproductive Traits: Multiple Ways to Account for Missing Pedigrees

open access: yesJournal of Animal Breeding and Genetics, Volume 143, Issue 1, Page 13-23, January 2026.
ABSTRACT Missing pedigrees are a common problem in most populations. Animals with unknown ancestors are usually treated as founders; however, this can underestimate inbreeding, not properly account for different base populations, and bias breeding values.

Semi‐arid river dynamics from the internal geometry of river deposits

open access: yesGeographical Research, Volume 63, Issue 4, Page 553-572, November 2025.
This article aims to understand fluvial dynamics based on the internal geometry of fluvial deposits, using radar morphostratigraphy in floodplains, especially those whose genesis is associated with anthropogenic controls, such as upstream of dams.

Functional Diversity of Neotropical Aquatic Hyphomycetes: Insights Into Environmental Drivers

open access: yesBiotropica, Volume 57, Issue 6, November 2025.
Subtropical streams host diverse hyphomycete assemblages than tropical one's. Larger saprotrophs with diverse conidia shapes dominate in subtropical areas. Cold and oxygenated waters have a positive effect on functional diversity. Poor litter in tropical favored the dominance of wood saprotrophs and endophytes.

A new species of Characidium (Characiformes: Crenuchidae) from the Iguaçu National Park, Rio Iguaçu basin, Paraná, Brazil

open access: yesJournal of Fish Biology, Volume 107, Issue 2, Page 454-465, August 2025.
Abstract A new species of Characidium is described from the Iguaçu National Park, Brazil. The new species can be diagnosed from the congeners by the absence of conspicuous vertical bars, blotches and spots along the sides of the body, the presence of a scaled isthmus and adipose fin, a series of scales below lateral line and the presence of a thin dark

From Herbarium to Landscape: New Records and Mapping Rare and Threatened Species of Brazilian Atlantic Rainforest

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
Botanical collections remain limited in the mountainous areas of the Brazilian Atlantic Rainforest, which compromises biogeographic knowledge of endangered and locally endemic species and many others that have not yet been described. These gaps hinder the accuracy of biodiversity indicators, limit the discovery and description of new species, restrict ...

Fish distribution across altitudinal gradients in the Upper Paraguay River Basin: Implications for conservation in the Pantanal region

open access: yesConservation Science and Practice, Volume 7, Issue 7, July 2025.
This paper approaches the patterns in fish distribution across the altitudinal gradient in the Upper Paraguay River basin, from uplands to the floodplain. We compiled more than 75,000 available fish records and registered 342 fish species and your distribution along altitudinal gradient. Floodplain portion have higher species diversity than headwaters,
