Does the Lack of Botanical Collections Affect the Knowledge and Conservation of Clusia L. (Clusiaceae) in the State of Amazonas, Brazil?

Feddes Repertorium, Volume 137, Issue 4, December 2026.
ABSTRACT Gaps in botanical collecting efforts limit our understanding of plant diversity and conservation, especially in megadiverse and poorly sampled regions like the Amazon. Using Clusia L., a species‐rich genus in the Amazon, as a model, this study evaluates how collecting deficits affect knowledge and species richness in Amazonas state, Brazil. We

Somatosensory Disturbance and Long‐Term Exposure to Methylmercury: A Comprehensive Review

Journal of Applied Toxicology, Volume 46, Issue 12, Page 4488-4496, December 2026.
ABSTRACT Chronic exposure to methylmercury remains a significant public health concern, particularly in populations with high fish consumption. Somatosensory disturbances are among the most frequently reported neurological manifestations, even at exposure levels below internationally established safety thresholds. This review aims to synthesize current
