Evidences That Host Genetic Background More Than the Environment Shapes the Microbiota of the Snail Bulinus truncatus, an Intermediate Host of Schistosoma Species

Molecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Microbiota have emerged as fundamental regulators of host physiology, shaping both ecological interactions and evolutionary trajectories. Yet, the determinants of microbiota diversity and structure in wild populations—particularly the respective roles of host genetics and environmental context—are still poorly understood.

Delineating Marine Planktonic Habitats Through the Biogeochemical‐Argo Array Data

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Phytoplankton play a crucial role in regulating marine biogeochemical pathways but studying their spatial and temporal dynamics often requires extensive and laborious oceanographic expeditions. Here, we report a novel use of Biogeochemical‐Argo data to delineate planktonic habitats in the Tropical North Atlantic Ocean (TNA).

Random encounter modelling as a viable method to estimate absolute abundance of reef fish

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 598-614, February 2026.
Abstract Remote underwater video (RUV) surveys are increasingly replacing diver‐based underwater visual censuses (UVCs) in fish ecology studies, especially on coral reefs. However, extracting reliable estimates of abundance or density from video footage is a major challenge, with most studies using a metric of relative abundance, MaxN (maximum number ...
