A Deep Metagenomic Snapshot as a Proof‐of‐Concept for Resource Generation: Simultaneous Assembly of Host, Food, and Microbiome Genomes From Stingless Bee Larval Food

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study serves as a proof‐of‐concept, demonstrating that deep shotgun sequencing of a single complex sample—stingless bee larval food—can simultaneously generate multiple genomic resources. From this dataset, we assembled three genomes (a near‐complete bacterium, a draft host mitochondrion, and a fragmented plant chloroplast) with varying ...

Blood indices of sheep fed with ensiled signal grass (Brachiaria decumbens)

open access: yesNew Zealand Journal of Agricultural Research, Volume 68, Issue 7, Page 1985-2002, December 2025.
ABSTRACT The Brachiaria species, particularly B. decumbens, is a key ruminant feed in the tropics but contains steroidal saponins that may cause toxicity, raising concerns for small ruminant farmers. Eighteen 6‐month‐old sheep were randomly assigned to three treatments over a 90‐day feeding trial: Negative control (fresh P.

Sedimentological and biofabric patterns for hybrid coquina deposits: Insights from wave tank experiments

open access: yesSedimentology, Volume 72, Issue 6, Page 1992-2024, October 2025.
ABSTRACT Hybrid bioclastic/siliciclastic coquinas are sedimentary accumulations typical of coastal‐ and shallow‐water settings, where wave breaking, longshore drift and wave shoaling drive sediment transport and control the final accumulations. These processes resulted in thick packages of sediments, as identified in the Lower Cretaceous depositional ...

Population structure of the bivalve Anomalocardia brasiliana, (Gmelin, 1791) in the semi-arid estuarine region of northeastern Brazil

open access: yesBrazilian Journal of Biology
For several decades, the bivalve mollusk Anomalocardia brasiliana has been extracted in estuarine areas in the semi-arid region of northeastern Brazil. However, information on both dynamics and abundance of their populations are missing. In this context,
