The evolution of scale sensilla in the transition from land to sea in elapid snakes [PDF]

open access: yesOpen Biology, 2016
Scale sensilla are small tactile mechanosensory organs located on the head scales of many squamate reptiles (lizards and snakes). In sea snakes and sea kraits (Elapidae: Hydrophiinae), these scale organs are presumptive scale sensilla that purportedly ...

Prioritising search effort to locate previously unknown populations of endangered marine reptiles

open access: yesGlobal Ecology and Conservation, 2020
Strategies aimed to conserve and manage rare species are often hindered by the lack of data needed for their effective design. Incomplete and inaccurate data on habitat associations and current species distributions pose a barrier to effective ...

VIVIPARITY IN SNAKES – HISTOLOGICAL STUDY OF THE RELATIONSHIP BETWEEN FETUS, FETAL MEMBRANES AND OVIDUCT IN EMERALD TREE BOA (Corallus caninus)

open access: yesSlovenian Veterinary Research, 2023
Viviparity is an important reproductive mode in reptiles from an evolutionary perspective. Viviparous reproduction is associated with certain physiological changes, probably in response to inadequate environmental conditions for egg development.

The molecular biogeography of the Indo‐Pacific: Testing hypotheses with multispecies genetic patterns

open access: yesGlobal Ecology and Biogeography, Volume 28, Issue 7, Page 943-960, July 2019., 2019
Abstract Aim To test hypothesized biogeographic partitions of the tropical Indo‐Pacific Ocean with phylogeographic data from 56 taxa, and to evaluate the strength and nature of barriers emerging from this test. Location The Indo‐Pacific Ocean. Time period Pliocene through the Holocene. Major taxa studied Fifty‐six marine species.

Quantitative Characterization of the Hemorrhagic, Necrotic, Coagulation‐Altering Properties and Edema‐Forming Effects of Zebra Snake (Naja nigricincta nigricincta) Venom

open access: yesJournal of Toxicology, Volume 2018, Issue 1, 2018., 2018
This study was designed to investigate the cytotoxicity and haemotoxicity of the Western barred (zebra) spitting cobra (Naja nigricincta nigricincta) venom to help explain atypical and inconsistent reports on syndromes by Namibian physicians treating victims of human ophidian accidents. Freeze‐dried venom milked from adult zebra snakes was dissolved in

Snake Venom PLA2, a Promising Target for Broad‐Spectrum Antivenom Drug Development

open access: yesBioMed Research International, Volume 2017, Issue 1, 2017., 2017
Snakebite envenomation is a neglected global health problem, causing substantial mortality, disability, and psychological morbidity, especially in rural tropical and subtropical zones. Antivenin is currently the only specific medicine for envenomation. However, it is restricted by cold storage, snakebite diagnosis, and high price.

Diversity of Aerobic Bacteria Isolated from Oral and Cloacal Cavities from Free‐Living Snakes Species in Costa Rica Rainforest

open access: yesInternational Scholarly Research Notices, Volume 2017, Issue 1, 2017., 2017
Costa Rica has a significant number of snakebites per year and bacterial infections are often complications in these animal bites. Hereby, this study aims to identify, characterize, and report the diversity of the bacterial community in the oral and cloacal cavities of venomous and nonvenomous snakes found in wildlife in Costa Rica.

Challenges of regulating commercial use of marine elapid snakes in the Indo‐Pacific

open access: yesConservation Biology, Volume 38, Issue 5, October 2024.
Abstract Marine elapid snakes are a diverse, predominantly Indo‐West Pacific species group. The persistent removal of some species has an unquantified but potentially dire impact on populations. We conducted the first comprehensive review of the trade in marine elapid snakes based on published literature (1974–2022) and trade data from the only species

Slowing taxon cycle can explain biodiversity patterns on islands: Insights into the biogeography of the tropical South Pacific from molecular data

open access: yesJournal of Systematics and Evolution, Volume 62, Issue 2, Page 201-214, March 2024.
Biodiversity on islands in the tropical South Pacific has mostly originated through recent colonization events less than 5 Mya from the closest source areas. Only the oldest archipelagos diverge from that pattern, having an older biota and lower diversification rates.

Sea snakes (Elapidae, Hydrophiinae) in their westernmost extent: an updated and illustrated checklist and key to the species in the Persian Gulf and Gulf of Oman

open access: yesZooKeys, 2016
The Persian Gulf is known as the westernmost distribution limit for sea snakes, except for Hydrophis platurus (Linnaeus, 1766) that reaches southeastern Africa.
