A study on the Cat Ba National Park, part of Ha Long Bay - Cat Ba Archipelago, reveals that plant species diversity is primarily driven by topography—specifically rock surface percentage and slope—rather than spatial isolation. The research identified 302 plant species across four distinct communities, with tree species making up half of the total richness. Contrary to expectations, isolated areas did not significantly contribute to biodiversity due to natural barriers like rough terrain that hinder seed dispersal. While non-tree species had no overall impact on tree regeneration, they negatively affected tree diversity in favorable lowland conditions, unlike harsh environments where such effects were absent. The findings highlight the importance of accessible lowland areas for high plant diversity but also note potential competition from non-tree species.

Plasma phosphorus levels in juvenile green turtles (Chelonia mydas) decrease significantly with distance from coastal regions, suggesting these levels could serve as a reliable indicator of environmental quality in feeding sites along the Brazilian coast. The study, conducted between 2012 and 2014, analyzed plasma calcium and phosphorus concentrations in 123 turtles from three distinct feeding areas: Vitória Bay (ES), Abrolhos Marine National Park (BA), and Atol das Rocas Biological Reserve (RN). These sites exhibit varying degrees of anthropization. Findings indicate that phosphorus levels drop as the distance from coastal regions increases, highlighting the potential impact of human activities on marine ecosystems and turtle health. The research recommends further studies to correlate food component phosphorus levels with plasma concentrations to strengthen this environmental quality indicator.

A study on Byzantine wall paintings from western Anatolia reveals that plaster characteristics vary significantly between sites, with Aigai displaying techniques such as marmorino and intonachino, indicative of earlier periods, while Anaia and Başpınar exhibit magnesium-rich lime plasters similar to post-iconoclastic period samples. The research used scanning electron microscopy (SEM-EDS), X-ray diffraction (XRD), and reflected light microscopy (RLM) to analyze plaster stratigraphy and microstructural properties from three sites: Anaia Church, Başpınar Church in Olympos, and a Byzantine setting and chapel in Aigai. The findings suggest intentional layering techniques aligned with painting methods, providing insights that can guide conservation efforts for these cultural heritage sites.
