Lipid monolayers: action of phospholipase A of Crotalus atrox and Naja naja venoms on phosphatidyl choline and phosphatidal choline

open access: yesJournal of Lipid Research, 1966
The activity of phospholipase A on phosphatidyl choline and phosphatidal choline spread as monolayers on phosphate buffers containing snake venom (Crotalus atrox or Naja naja) was studied by measuring the fall of surface potential as a function of time ...

DNA barcoding elucidates the population genetic diversity of venomous cobra species (Reptilia: Elapidae) in Indo-Bangladesh region

open access: yesMitochondrial DNA. Part B. Resources, 2020
The DNA barcode data of venomous cobra species (Naja naja and Naja kaouthia) are limited in the global database, especially from India and Bangladesh. Owing to the rapid success of DNA barcoding for discriminating a variety of species around the world ...

The interaction of dialkyl ether lecithins with phospholipase A2 (Naja naja naja).

open access: yesJournal of Biological Chemistry, 1983
Dialkyl lecithins are nonhydrolyzable substrate analogues for phospholipase A2 (Naja naja naja). Short chain dialkyl lecithins (which form monomers and micelles), and long chain ether-linked lecithins (which form bilayers or can be solubilized in detergent micelles) have been used to study phospholipase A2/phospholipid interactions.

Perspectives on the Effect of Incubation Temperature on Pine Snake Hatchlings

open access: yesEthology, Volume 132, Issue 3, Page 149-174, March 2026.
Effect of timing of egg‐laying and incubation temperature on the possible phenology of events for early egg‐laying females (laying June 15, the earliest laying date), the mid‐laying date (July 4), and late egg‐laying females (July 17, the latest egg‐laying date). Based on data from many papers.

Herbariomics and the peculiar case of Alisma wahlenbergii (Alismataceae)

open access: yesTAXON, Volume 75, Issue 1, February 2026.
Abstract Species identification and delimitation in aquatic plants can be challenging due to their often simple, plastic, and convergent morphology. This has led to varying taxonomic opinions in many genera, including Alisma. One debated case is the narrowly endemic A. wahlenbergii, which occurs submerged in the Baltic Sea region.

Proteomic characterization of the thermostable toxins from Naja naja venom

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2010
Naja naja snake venom presents abundant thermostable peptides. Many of them possess useful pharmacological activity that may be employed for drug development.

How the Cobra Got Its Flesh-Eating Venom: Cytotoxicity as a Defensive Innovation and Its Co-Evolution with Hooding, Aposematic Marking, and Spitting [PDF]

open access: yes, 2017
The cytotoxicity of the venom of 25 species of Old World elapid snake was tested and compared with the morphological and behavioural adaptations of hooding and spitting. We determined that, contrary to previous assumptions, the venoms of spitting species

Quantifying aquatic plant commonness and co‐occurrence across scales to support ecological understanding and management

open access: yesJournal of Ecology, Volume 114, Issue 2, February 2026.
Macrophyte commonness and co‐occurrence were quantified to support objective classifications of species distributions in Midwestern lakes. This framework provides a practical tool for conservation prioritization (e.g. identifying species that are rare at regional and local scales that may be more susceptible to local disturbance), invasive species risk

Community‐ and species‐level responses of reptiles to an avian ecosystem engineer

open access: yesJournal of Zoology, Volume 328, Issue 2, Page 203-209, February 2026.
Reptiles in southern Africa's Kalahari desert occur at higher abundances and greater species richness under trees with sociable weaver colonies, than those without. This finding substantially expands our knowledge of how commonly reptile communities might respond to ecosystem engineers.

Comparative characterization of two toxic phospholipases A2 from Indian cobra (Naja naja naja) venom

open access: yesToxicon, 1992
Indian cobra venom contains many phospholipase A2 (PLA2) toxins. In the present study two toxic PLA2s have been purified from the Indian cobra (Naja naja naja) venom by column chromatography. The NN-XIa-and NN-XIb-PLA2s have mol. wts between 10,700 and 15,000.
