Do New World pitvipers “scale‐down” at high elevations? Macroecological patterns of scale characters and body size

Ecology and Evolution, Volume 9, Issue 16, Page 9362-9375, August 2019., 2019
New World Pitvipers show a contra‐Bergmann's pattern between elevation and body size. Abstract Bergmann's rule describes the macroecological pattern of increasing body size in response to higher latitudes and elevations. This pattern is extensively documented in endothermic vertebrates, within and among species; however, studies involving ectotherms ...

Ethnobotanic study of Randia aculeata (Rubiaceae) in Jamapa, Veracruz, Mexico, and its anti-snake venom effects on mouse tissue

Journal of Venomous Animals and Toxins including Tropical Diseases, 2012
In Mexico, medicinal plants are widely used. The use of Randia aculeata by healers against snakebites has never been scientifically tested in relation to possible effects on blood parameters and muscle tissue damage. Interviews were carried out in Jamapa,

Stabilising the Integrity of Snake Venom mRNA Stored under Tropical Field Conditions Expands Research Horizons. [PDF]

, 2016
BACKGROUND Snake venoms contain many proteinaceous toxins that can cause severe pathology and mortality in snakebite victims. Interestingly, mRNA encoding such toxins can be recovered directly from venom, although yields are low and quality is unknown ...

First record of Porocephalus cf. clavatus (Pentastomida: Porocephalida) as a parasite on Bothrops asper (Squamata: Viperidae) in Costa Rica

Brazilian Journal of Biology
Pentastomids are parasites that infect respiratory cavities of vertebrates, they are pretty common but poorly known in wildlife veterinary. A Bothrops asper snake (Garman, 1884) was captured in the Caribbean region of Costa Rica and had its lung infested

Unraveling Biogeographic Boundaries Within the Sierra Madre Oriental, México: An Endemicity Analysis Using a Taxonomically Diverse Dataset

Ecology and Evolution, Volume 15, Issue 1, January 2025.
We provide boundaries of the Sierra Madre Oriental in Mexico through a multi‐taxa endemicity analysis. ABSTRACT The Sierra Madre Oriental (SMO) is a significant mountain range and one of Mexico's 14 biogeographical provinces. Its delimitation has been debated.

Selfish or altruistic? An analysis of alarm call function in wild capuchin monkeys, Cebus apella nigritus [PDF]

, 2008
Alarm calls facilitate some antipredatory benefits of group living but may endanger the caller by attracting the predator's attention. A number of hypotheses invoking kin selection and individual selection have been proposed to explain how such behaviour

Snake venom toxins: Potential anticancer therapeutics

Journal of Applied Toxicology, Volume 44, Issue 5, Page 666-685, May 2024.
Abstract Snake venom contains a cocktail of compounds dominated by proteins and peptides, which make up the toxin. The toxin components of snake venom attack several targets in the human body including the neuromuscular system, kidney and blood coagulation system and cause pathologies. As such, the venom toxins can be managed and used for the treatment
