Climate change and rapid habitat degradation have led to a decline in the population of snakes. Hence constant monitoring their diversity wellbeing is necessary. During present study under our Sarpa Sathi project, we surveyed for snake using time-constrained search, incidental encounters around Mysore city, Karnataka, India, first time. period three years, identified 24 species snakes, belongs ...

BACKGROUND The attitudes and perceptions of people toward animals are influenced by sociodemographic factors, such as formal education and gender, and by personal experience. Understanding these interactions is critical for the establishment of conservation strategies for animals that have conflictual relationships with humans, such as snakes. Our study aims to explain how perceptions and the h...

This study describes how the body temperatures (Th) of individual garter snakes varied on a daily basis under field conditions. Temperature-sensitive radio transmitters were surgically implanted into 10 Thamnophis elegans vagrans in eastern Wash? ington. The snakes were released and monitored at 15-min intervals for periods of up to several days from June 1979 to May 1980. Operative environment...

The physics behind the snake’s slither has provoked much debate. Previous analyses suggested that snakes push against objects to propel themselves forward. This assumption has driven the design of search-and-rescue robotic snakes with wheels that go back and forth but not sideways. David Hu et al. propose that friction caused by the snake’s belly scales plays a critical role in movement. The au...

We investigated possible interactions between melatonin and corticosterone in modulating the reproductive behavior of male red-sided garter snakes (Thamnophis sirtalis parietalis) following spring emergence. We also examined whether melatonin's modulatory actions could be explained by its potential properties as a serotonin receptor antagonist. Exogenous corticosterone significantly reduced cou...

Humans quickly detect the presence of evolutionary threats through visual perception. Many theorists have considered humans to be predisposed to respond to both snakes and spiders as evolutionarily fear-relevant stimuli. Evidence supports that human adults, children, and snake-naive monkeys all detect pictures of snakes among pictures of flowers more quickly than vice versa, but recent neurophy...

Snakes are purported to drink by sucking water into their mouths and then compressing the oral cavity to force water into the oesophagus. Video recordings of drinking behaviour in 23 snakes representing 14 species from three families, combined with simultaneous recordings of water volumes consumed, show that all the snakes vary widely in the amount of water taken in when drinking. This variatio...

A long-standing hypothesis for the adaptive radiation of macrostomatan snakes is that their enlarged gape--compared to both lizards and basal snakes--enables them to consume "large" prey. At first glance, this hypothesis seems plausible, or even likely, given the wealth of studies showing a tight match between maximum consumed prey mass and head size in snakes. However, this hypothesis has neve...

In contour integration, increased difficulty in detection and shape discrimination of a chain of parallel elements (a ladder contour) compared to collinear elements (a snake contour) suggests more extensive processing of ladders than of snakes. In addition, conceptual similarities between ladders and textures - which also involve grouping of parallel elements - raises the question whether ladde...

We present a method for searching for simple achordal open paths (snakes) in n-dimensional hypercube graphs (the box). Our technique first obtains exemplary snakes using an evolutionary algorithm previously responsible for defining the best-known lower bounds in n-cubes for n = 9, 10, 11, and 12. These snakes are used to define a pruning model that constrains the search space. A depth-first sea...
