15 Noninvasive genetic approaches enable biomonitoring without the need to directly observe or 16 disturb target organisms. Environmental DNA (eDNA) methods have recently extended this 17 approach by assaying genetic material within bulk environmental samples without a priori 18 knowledge about the presence of target biological material. This paper describes a novel and 19 promising source of n...
Black widow spiders (members of the genus Latrodectus) are widely feared because of their potent neurotoxic venom. α-Latrotoxin is the vertebrate-specific toxin responsible for the dramatic effects of black widow envenomation. The evolution of this toxin is enigmatic because only two α-latrotoxin sequences are known. In this study, ~4 kb α-latrotoxin sequences and their homologs were characteri...
Brown widow spider (Latrodectus geometricus) venom (BrWSV) produces few local lesions and intense systemic reactions such as cramps, harsh muscle pains, nausea, vomiting and hypertension. Approximately 16 protein bands under reducing conditions and approximately 14 bands under non-reducing conditions on a 12.5% sodium dodecyl sulfate-polyacrylamide gel electrophoresis were observed. Neurotoxic ...
