Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

Archaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.
