Shallow phylogeographic structure in the declining Mexican Lance-headed Rattlesnake, Crotalus polystictus (Serpentes: Viperidae) [PDF]

Phyllomedusa: Journal of Herpetology, 2012
We investigated matrilineal relationships among populations of the Mexican lance-headed rattlesnake (Crotalus polystictus), a pitviper inhabiting high-elevation valleys of the densely populated southernMexican Plateau.

Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.

Demonstration, validation, and application of hyperspectral microscopy for the collection of cyanobacterial spectral signatures

Limnology and Oceanography: Methods, EarlyView.
Abstract Cyanobacterial and other algal blooms are an environmental concern in waterbodies worldwide. While these blooms are a nuisance for recreational activities, they can also be harmful to human and wildlife health when the algae produce and release toxins.

Bioquímica plasmática de cascavéis (Caudisona durissa LINNAEUS, 1758) em cativeiro Blood biochemical parameters from captivity rattlesnake (Caudisona durissa LINNAEUS, 1758)

Ciência Rural, 2010
Acidentes com seres humanos envolvendo a espécie Caudisona durissa possuem a mais alta taxa de letalidade dentre os viperídeos brasileiros. Ressalta-se então a importância para a saúde pública da criação dessa espécie em cativeiro para produção de soro ...

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

Oikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Acute hepatotoxicity of Crotalus durissus terrificus (South American rattlesnake) venom in rats

Journal of Venomous Animals and Toxins including Tropical Diseases, 2009
Venom of the South American rattlesnake, Crotalus durissus terrificus (Cdt), presents myotoxic and neurotoxic outcomes, but reports on its effects on the liver are scarce.

Autonomous Navigation in Large‐Scale Underground Environments Based on a Purely Topological Understanding of Tunnel Networks

Journal of Field Robotics, EarlyView.
ABSTRACT This work presents a non‐geometrical navigation approach based on a purely topological understanding of underground environments. By conceptualizing subterranean scenarios as a set of tunnels that intersect with each other, and taking a navigation approach based on topological instructions, we simplify the navigation problem to the sequential ...

Detection of Leptospira in cane toads (Rhinella jimi) from urban and rural Paraíba, Brazil

Veterinary Record, EarlyView.
Abstract Background Leptospirosis is a significant zoonosis in tropical regions, where poor sanitation and favourable climate aid its spread. Synanthropic animals such as the cane toad (Rhinella jimi), which share environments with both people and wild and domestic animals, may harbour Leptospira and contribute to urban and rural transmission cycles ...
