Proteomic profile of the venom of three dark-colored Tityus (Scorpiones: Buthidae) from the tropical rainforests of Costa Rica
(2023)
Objective: We aimed to elucidate the potential differences in the venom peptide sequences of three Tityus species
from Costa Rican rainforests: T. jaimei, T. championi and T. dedoslargos, compared to T. cf. asthenes ...
Venomics of the poorly studied hognosed pitvipers Porthidium arcosae and Porthidium volcanicum
(2021)
We report the first proteomics analyses of the venoms of two poorly studied snakes, the Manabi hognosed pitviper Porthidium arcosae endemic to the western coastal province of Manabí (Ecuador), and the Costa Rican hognosed ...
Proteomic and toxicological analysis of the venom of Micrurus yatesi and its neutralization by an antivenom
(2022)
Coralsnakes belong to the family Elapidae and possess venoms which are lethal to humans and can be grouped based on the predominance of either three finger toxins (3FTxs) or phospholipases A2 (PLA2s). A proteomic and ...
Venomics of the Duvernoy's gland secretion of the false coral snake Rhinobothryum bovallii (Andersson, 1916) and assessment of venom lethality towards synapsid and diapsid animal models
(2020)
The Duvernoy's gland secretory proteome of the false coral snake Rhinobothryum bovallii (Costa Rica), unveiled applying bottom-up venomics, comprises a handful of toxins belonging to only three protein families, three-finger ...
Regional warming and the thermal regimes of American crocodile nests in the Tempisque Basin, Costa Rica
(2016-06-11)
Spatial variation in global climate change makes population-specific responses to this enigmatic threat pertinent on a regional scale. Organisms with temperature-dependent sex determination (TSD) potentially possess a ...
A cryptic palm-pitviper species (Squamata: Viperidae: Bothriechis) from the Costa Rican highlands, with notes on the variation within B. nigroviridis
(2016-07-15)
Middle America is one of the most biodiverse regions in the world, harboring an exceptional number of rare and endemic species. This is especially true of Middle American cloud forests, where montane specialists occupy ...
The Phospholipase A2 Homologues of Snake Venoms: Biological Activities and Their Possible Adaptive Roles
(2009)
A particular subgroup of toxins with phospholipase A2 (PLA2) structure, but devoid of this enzymatic activity, is commonly found in the venoms of snakes of the family Viperidae, and known as the PLA2 homologues. Among ...
Hydrology Affects Environmental and Spatial Structuring of Microalgal Metacommunities in Tropical Pacific Coast Wetlands
(2016-02-22)
The alternating climate between wet and dry periods has important effects on the hydrology and therefore on niche-based processes of water bodies in tropical areas. Additionally, assemblages of microorganism can show spatial ...
Venomics of the scorpion Tityus ocelote (Scorpiones, Buthidae): Understanding venom evolution in the subgenus Archaeotityus
(2022)
The subgenus Tityus (Archaeotityus) includes small variegated species considered until recently, a basal group within Tityus, one of the most diverse and medically relevant genera of scorpions in the New World. Archaeotityus ...
Venom characterization of the bark scorpion Centruroides edwardsii (Gervais 1843): composition, biochemical activities and in vivo toxicity for potential prey
(2019)
In this study, we characterize the venom of Centruroides edwardsii, one of the most abundant scorpions in urban
and rural areas of Costa Rica, in terms of its biochemical constituents and their biological activities. C. ...
