Habitat loss can lead to biotic homogenization (decrease in β diversity) or differentiation (increase in β diversity) of biological communities. However, it is unclear which of these ecological processes predominates in human-modified landscapes. We used data on vertebrates, invertebrates, and plants to quantify β diversity based on species occurrence and abundance among communities in 1367 landscapes with varying amounts of habitat (<30%, 30-60%, or >60% of forest cover) throughout the Brazilian Atlantic Forest.

MELAS syndrome, characterized by mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes, represents a devastating mitochondrial disease, with the stroke-like episodes being its primary manifestation. Arginine supplementation has been used and recommended as a treatment for these acute attacks; however, insufficient evidence exists to support this treatment for MELAS. The mechanisms underlying the effect of arginine on MELAS pathophysiology remain unclear, although it is hypothesized that arginine could increase nitric oxide availability and, consequently, enhance blood supply to the brain.

Article Synopsis
  • L-Arginine (L-ARG) might help people with a disease called MELAS, which affects how cells produce energy.
  • It is thought that L-ARG can improve blood flow and help with some problems caused by the disease by increasing a substance called nitric oxide (NO) in the body.
  • However, the study found that while L-ARG didn’t change how well the energy parts of the cells worked, it did lower certain harmful proteins in cells with the disease, which may help patients feel better.
