Understanding Biological Roles of Venoms Among the Caenophidia: The Importance of Rear-Fanged Snakes.

open access: yesIntegrative and Comparative Biology, 2016
Snake venoms represent an adaptive trophic response to the challenges confronting a limbless predator for overcoming combative prey, and this chemical means of subduing prey shows several dominant phenotypes. Many front-fanged snakes, particularly vipers,

Near‐Freezing‐Temperature Golgi Neuronal Staining for X‐ray Imaging of Human Brain

open access: yesAdvanced Science, EarlyView.
A near‐freezing temperature staining strategy, combined with a mercury chloride‐based method, effectively preserves delicate neuronal structures in post‐mortem frozen human brain tissues by minimizing autolysis. This approach enables uniform labeling across centimeter‐scale slices and, when integrated with synchrotron‐based X‐ray microscopy, achieves ...

Experimental Infection of Snakes with Ophidiomyces ophiodiicola Causes Pathological Changes That Typify Snake Fungal Disease

open access: yesmBio, 2015
Snake fungal disease (SFD) is an emerging skin infection of wild snakes in eastern North America. The fungus Ophidiomyces ophiodiicola is frequently associated with the skin lesions that are characteristic of SFD, but a causal relationship between the ...

Microhabitat use by species of the genera Bothrops and Crotalus (Viperidae) in semi-extensive captivity

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2012
Many factors influence microhabitat including climate and the occurrence of predators, prey and suitable shelters. The influence of predators in a semi-extensive breeding system is minimized due to frequent monitoring of the area.
