Genetic variability, management, and conservation implications of the critically endangered Brazilian pitviper Bothrops insularis

open access: yesEcology and Evolution, Volume 10, Issue 23, Page 12870-12882, December 2020., 2020
This is the first report focusing on the conservation genetics of Bothrops insularis, an endemic critically endangered Brazilian snake. We recovered low (allelic content) and medium (heterozygosity) genetic diversity indexes, significant inbreeding coefficient for the in situ population and a slight genetic structure within and between populations ...

Biological characterization of a myotoxin phosphoplipase A2 homologue purified from the venom of the snake Bothrops moojeni

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2011
A myotoxin phospholipase A2 homologue, BmooMtx, was isolated from the venom of Bothrops moojeni by a combination of ion-exchange chromatography on DEAE-Sephacel column and gel filtration on Sephadex G-75. SDS-PAGE showed the enzyme to be a monomer with a

Rapid purification of serine proteinases from Bothrops alternatus and Bothrops moojeni venoms

open access: yesToxicon, 2013
Envenomation by Bothrops species results, among other symptoms, in hemostatic disturbances. These changes can be ascribed to the presence of enzymes, primarily serine proteinases some of which are structurally similar to thrombin and specifically cleave fibrinogen releasing fibrinopeptides.

Evidence of facultative parthenogenesis in three Neotropical pitviper species of the Bothrops atrox group [PDF]

open access: yesPeerJ, 2020
We examined four suspected cases of facultative parthenogenesis in three species of a neotropical lineage of pitvipers of the Bothrops atrox group. Reproduction without mating was observed in captive females of B. atrox, B. moojeni and B. leucurus housed

Genetic relationships among species of the genus Bothrops based on RAPD markers

open access: yesBrazilian Archives of Biology and Technology, 2005
The genetic relationships among 11 species of Bothrops found in Brazil were determined using random amplified fragment (RAPD) information. A total of 239 amplified bands were scored using 20 aleatory primers.
