ilam province in southwest iran possesses varied climatic and geographical conditions leading to rich biodiversity. an investigating of the status of snakes in the province was carried out from june 2005 to march 2010. a total of 103 specimens were collected and identified. six families, 20 genera, and 26 species are represented, including boidae: eryx (eryx) jaculus turcicus; colubridae: colub...

Snakes are cold-blooded reptiles that often found from the lowlands, headlands, soil, trees, freshwater, brackish water, to seawater, except in areas with low temperatures such as poles. Rattlesnake bites continue occur anytime and anywhere. Although, currently, there is a covid-19 pandemic Indonesia. The community needs know identify some basic knowledge about snakes. This training was held on...

In this technical report, we address the problem of recovering the camera radial distortion coefficients from one image. In particular, we present three interactive methods where the user indicate lines in the single image. The first method is the most direct: the manually chosen points are used to compute the radial distortion parameters. The second and third methods allow the user to draw sna...

We investigated the mechanisms by which temperature induces seasonal reproductive behavior in red-sided garter snakes (Thamnophis sirtalis parietalis). Specifically, we addressed whether elevated temperatures during winter dormancy influence (1) diel melatonin and corticosterone rhythms; (2) sex steroid hormone and corticosterone profiles; and (3) the expression of reproductive behavior followi...

There is growing evidence from both behavioral and neurophysiological approaches that primates are able to rapidly discriminate visually between snakes and innocuous stimuli. Recent behavioral evidence suggests that primates are also able to discriminate the level of threat posed by snakes, by responding more intensely to a snake model poised to strike than to snake models in coiled or sinusoid...

Batesian mimicry, in which harmless species (mimics) deter predators by deceitfully imitating the warning signals of noxious species (models), generates striking cases of phenotypic convergence that are classic examples of evolution by natural selection. However, mimicry of venomous coral snakes has remained controversial because of unresolved conflict between the predictions of mimicry theory ...

Papuan taipans (Oxyuranus scutellatus canni), death adders (Acanthophis spp.) and Papuan blacksnakes (Pseudechis papuanus) are the most dangerous snakes along the Papuan coastline. Although the Papuan blacksnake is rare, the Papuan taipan is very common in parts of Milne Bay, Central, Gulf and Western provinces, and is the commonest venomous snake implicated in cases of snakebite. Deaths adders...

We propose a novel Active Volume Model (AVM) which deforms in a free-form manner to minimize energy. Unlike Snakes and level-set active contours which only consider curves or surfaces, the AVM is a deforming object model that has both boundary and an interior area. When applied to object segmentation and tracking, the model alternates between two basic operations: deform according to current ob...
