Island‐restricted reptiles are more threatened but less studied than their mainland counterparts

Conservation Science and Practice, Volume 8, Issue 3, March 2026.
Reptiles are highly diverse on islands, yet there is no comprehensive overview of island‐restricted reptiles (IRRs) regarding their distribution, threat status, and research efforts. Our assessment revealed that despite IRRs comprising nearly a quarter of global reptile species and 30.8% being threatened, only 7.2% of the literature focuses on them ...

On the Main Branches of the Pulmonary Artery in Some Viperidae [PDF]

Bijdragen tot de Dierkunde, 1949
In all snakes, the Boidae and Xenopeltidae excepted, only the right lung is well developed, while the left lung is rudimentary or absent (BUTLER, 1895). The right lung consists of an anterior alveolar part that is strongly vascularized, and of a posterior smooth-walled air-sac that is anangious.

Local Ecological Knowledge and Cultural Perceptions of Snakes in Sudan

Ecology and Evolution, Volume 16, Issue 1, January 2026.
In Sudan, snakes are viewed through a mix of ecological, cultural, and spiritual lenses, shaping both conservation attitudes and health responses. Our survey (n = 192) across 16 states revealed frequent encounters, polarized conservation views, widespread killing of snakes, reliance on traditional remedies, and strong public support (95%) for ...

Polymeric Nanoparticles for the Diagnosis and Treatment of Snakebite

Macromolecular Chemistry and Physics, Volume 227, Issue 1, 15 January 2026.
Snakebite envenomation affects between 1.8 and 5.5 million people annually, many of whom suffer disabilities or even death. Current antivenoms are composed of plasma‐derived antibodies. However, there remains an underexplored opportunity to utilise polymer‐based nanoparticles.

The primary structure of three hemoglobin chains from the indigo snake (Drymarchon corais erebennus, Serpentes): First evidence for αD chains and two β chain types in snakes [PDF]

, 2002
The hemoglobin of the indigo snake (Drymarchon corais erebennus, Colubrinae) consists of two components, HbA and HbD, in the ratio of 1:1. They differ in both their alpha and beta chains.
