Systematics of Marmosa Subgenus Micoureus With Emphasis in ‘rapposa’ Group (Didelphidae, Marmosini): Geographic Variation and Revalidation of M. budini

open access: yesZoologica Scripta, EarlyView.
ABSTRACT Micoureus is the most species‐rich subgenus within the genus Marmosa. Conflicting arrangements regarding the number of species comprising this subgenus have been proposed and the validity of M. budini has been debated. Here, we used an approach integrating genetic and morphological data were conducted to reanalyze the ‘rapposa’ group ...

A Spatial Clustering Approach of Economic Activities: An Application to the Agribusiness Sector in Brazil's Midwest Region

open access: yesGeographical Analysis, Volume 58, Issue 4, October 2026.
ABSTRACT The spatial distribution of economic activities is central to regional economics. However, empirical tools for comparing industries based on the similarity of their spatial distributions remain limited. Traditional cluster analysis typically ignores geographical distance and connectivity, while spatial methods focus on clustering places rather

Soil carbon stock and physical attributes under land‐use chronosequence in the Brazilian Cerrado

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Land‐use changes impact soil physical quality and carbon stocks. Most studies evaluating the conversion of native Brazilian Cerrado to agriculture focus on surface soil layers (up to 40 cm), with fewer examining deeper layers (0–100 cm). This study assessed the impacts of different land‐use systems on soil physical attributes and soil organic ...

Lectotypification and Nomenclatural Notes on Four Names in Alismataceae From the Americas

open access: yesNew Zealand Journal of Botany, Volume 64, Issue 3, September 2026.
Four Alismataceae names from the Americas are investigated. Second‐step lectotypes are designated for Hydrocleys martii and Sagittaria seubertiana according to the Art. 9.17 of Madrid Code. A lectotype is designated for Sagittaria isoetiformis, resolving a 130‐year nomenclatural ambiguity. Finally, the previously proposed neotypification for Sagittaria

Genetic Indicators of Performance Resilience in Barrel Racing Quarter Horses

open access: yesAnimal Genetics, Volume 57, Issue 4, August 2026.
ABSTRACT Resilience, defined as the capacity to maintain consistent performance under variable conditions, has emerged as a relevant breeding objective in livestock systems, yet remains largely unexplored in equine populations. The objectives of this study were to (1) derive indicators of resilience from longitudinal barrel racing time (BRT) records in

Use of Restricted Nursing and a Bovine Appeasing Substance on the Welfare, Growth Performance, and Response to Vaccination of Beef Calves at Weaning

open access: yesAnimal Research and One Health, Volume 4, Issue 3, Page 314-321, August 2026.
The effects of restricted nursing (RN) and the administration of a bovine appeasing substance (BAS) on days −8 and 0 in relation to weaning were evaluated. Both strategies were effective in improving the growth performance of beef calves. Regarding welfare, BAS ‐especially on day 0‐ was more effective than RN.

Effects of Araticum (Annona crassiflora Mart.) By‐Product on Intestinal Health Parameters in High‐Fat Diet‐Fed Mice

open access: yesFood Science &Nutrition, Volume 14, Issue 8, August 2026.
Araticum (Annona crassiflora Mart.) by‐product supplementation at 200 or 400 mg/kg for 30 days did not improve body weight, glucose tolerance, or obesity‐related metabolic markers in high‐fat diet‐fed mice. However, it increased fecal moisture and intestinal mucus, reduced fecal pH, and promoted changes in gut bacterial richness, indicating potential ...
