Divergence in life-history traits among three adjoining populations of the sea snake Emydocephalus annulatus (Hydrophiinae, Elapidae) [PDF]
Scientific Reports, 2022 Life-history traits such as rates of growth, survival and reproduction can vary though time within a single population, or through space among populations, due to abiotically-driven changes in resource availability.

Complete mitochondrial genome of the Ijima's Sea Snake (Emydocephalus ijimae) (Squamata, Elapidae) [PDF]
Mitochondrial DNA. Part B. Resources, 2019 In this study, we provide the first report of the complete mitochondrial genome of Emydocephalus ijimae. The mitogenome length is 18,259 bp and includes 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and three non-coding regions.

The Unusual Metalloprotease-Rich Venom Proteome of the Australian Elapid Snake Hoplocephalus stephensii [PDF]
Toxins, 2022 The Australasian region is home to the most diverse elapid snake radiation on the planet (Hydrophiinae). Many of these snakes have evolved into unique ecomorphs compared to elapids on other continents; however, their venom compositions are poorly known ...

Novel vascular plexus in the head of a sea snake (Elapidae, Hydrophiinae) revealed by high-resolution computed tomography and histology [PDF]
Royal Society Open Science, 2019 Novel phenotypes are often linked to major ecological transitions during evolution. Here, we describe for the first time an unusual network of large blood vessels in the head of the sea snake Hydrophis cyanocinctus.

Horizontal Transposon Transfer and Its Implications for the Ancestral Ecology of Hydrophiine Snakes. [PDF]
Genes (Basel), 2022 Transposable elements (TEs), also known as jumping genes, are sequences able to move or copy themselves within a genome. As TEs move throughout genomes they often act as a source of genetic novelty, hence understanding TE evolution within lineages may ...

VenomCap: An exon-capture probe set for the targeted sequencing of snake venom genes. [PDF]
Mol Ecol ResourAbstract Snake venoms are complex mixtures of toxic proteins that hold significant medical, pharmacological and evolutionary interest. To better understand the genetic diversity underlying snake venoms, we developed VenomCap, a novel exon‐capture probe set targeting toxin‐coding genes from a wide range of elapid snakes, with a particular focus on the ...

When to shed? Patterns and drivers of time to first ecdysis in snakes. [PDF]
Ecol Evol, 2023 We assessed patterns in time to postnatal ecdysis in snake species, and related measures to various biological traits. Time to postnatal ecdysis can be shorter or longer than the ancestral state, which we estimated at 8–9 days, indicating that there are several competing drivers for time to postnatal ecdysis.

Annotated checklist of semi- venomous and venomous snakes of Iraq [PDF]
Iranian Journal of Animal Biosystematics, 2016 This study includes a check-list of semi-venomous and venomous snakes in Iraq along with their distribution and classification. Collectively, from the family Clubridae, three genera, and seven species of semi-venomous snakes and from the families ...

Ecology and Evolution, Volume 12, Issue 4, April 2022., 2022 We show that sea kraits are dependent on microhabitats in old‐growth coastal forest of a topographically flat Fijian atoll for terrestrial activities. Therefore, environmental heterogeneity and high‐quality terrestrial habitats, as well as healthy coral reefs, are essential for sea kraits, making them good flagship species for advocating integrated ...
