Optimizing snake locomotion in the plane. II. Large transverse friction [PDF]
We determine analytically the form of optimal snake locomotion when the coefficient of transverse friction is large, the typical regime for biological and robotic snakes. We find that the optimal snake motion is a retrograde traveling wave, with a wave amplitude that decays as the -1/4 power of the coefficient of transverse friction. This result agrees

Our study aimed to provide additional evidence for sub‐lethal effects of roadways on animal behavior. In this case, we found strong support for increased road interactions by males during mating seasons and the possibility of reduced mate searching efficiency by those males interacting with roads that warrants future investigation.

Ritualistic Male–Male Combat of the Northern King Cobra (Ophiophagus hannah) in Thailand
Following the recent taxonomic split of the king cobra complex, it is important to provide new information and context to behaviors and natural history linked to each new species. We therefore provide detailed observations of ritualistic male–male combat of the newly described northern king cobra (Ophiophagus hannah).

Illegal melamine analogs are added to food to make it appear as if it contains more protein. ABSTRACT Illegal melamine analogs are added to food to make it appear as though it contains more protein. These substances have negative impacts on both humans and animals in high quantities. The present paper examines how cobra venom shields rats from melamine‐

Danger versus fear: A key to understanding biophobia
Abstract Which animals do people fear most, and why? Exploring animal fears in humans is crucial for understanding reactions in the face of danger, addressing both innate and learned determinants. Because of the central role they are thought to have played in primate evolution, most studies have focused on the fear of snakes.

Abstract Rural communities in Amazonia rely on harvesting Mauritia flexuosa fruit, a dominant peatland palm, for their subsistence and income. However, these palms are felled to harvest the fruits, which has led to reduced resource availability due to the pressure exerted by the increasing fruit demand.

Background PAPP is widely used in Australia as a potent vertebrate bait, with potential for off‐target ingestion and poisoning in domestic dogs. Whilst toxicosis and resulting methaemoglobinaemia is anecdotally known to occur, this is the first description in the literature.

Graceful Labellings of Various Cyclic Snakes [PDF]
In this paper, we present a new sufficiency condition to obtain a graceful labelling for every $kC_{4n}$ snake and use this condition to label every such snake for $n=1,2,\ldots,6$. Then, we extend this result to cyclic snakes where the cycles lengths vary. Also, we obtain new results on the (near) graceful labelling of cyclic snakes based on cycles of

Relative and absolute Lefschetz standard conjectures for some Lagrangian fibrations
Abstract We show that the hyper‐Kähler varieties of OG10‐type constructed by Laza–Saccà–Voisin (LSV) verify the Lefschetz standard conjecture. This is an application of a more general result, stating that certain Lagrangian fibrations verify this conjecture. The main technical assumption of this general result is that the Lagrangian fibration satisfies

Investigating snake venom variation to mitigate snakebite envenomation in Indonesia [PDF]
Snakebite envenoming is one of the neglected tropical diseases and is still rarely studied in Indonesia. The high diversity of venomous snakes in Indonesia is one of the challenges.
