Article Synopsis
- The primary aim of rare plant translocation is to establish self-sustaining populations that can endure over time, but most studies only analyze short-term success metrics like survival and reproduction.
- A comprehensive analysis of 275 monitored at-risk plant translocations revealed that management techniques play a critical role in short-term success, while site attributes and species traits are more significant for long-term population persistence.
- Key findings indicated that larger founder sizes enhance reproductive potential, whereas poor habitat quality and low seed production in species heighten the risk of extinction in the long run; effective management can help mitigate these challenges.
Methylmercury in biota downstream of Arivaca lake, Arizona, USA.
Arch Environ Contam Toxicol
April 2014
Concentrations of total mercury (Hg) and methylmercury (MeHg) were determined in water, sediment, periphyton, spiders, and amphibians from the streams and desert marsh downstream from Arivaca Lake, Arizona, to better understand their distribution and bioaccumulation. Mean concentrations of MeHg in water ranged from 0.09 to 0.
