Despite the ongoing worldwide trade in reptiles, monitoring and management systems are only recently being developed for exploited lizards and snakes. We studied the tegu lizard (Tupinambis spp.) management and harvest monitoring program in Paraguay as a model for commercially exploited reptile management. Tegu lizards are among the most exploited reptiles in the world, with current quotas for ...

Pterygosoma patagonica n. sp. (Acari: Pterygosomatidae) is described from endemic iguanid lizards (Liolaemus spp.) of Argentina, based on its morphology. This external parasite is also known to parasitize Old World agamid lizards.

LPG is an exceptional energy source due to its origin, benefits and applications in various sectors viz. domestic, commercial and industries. With an immediate and global availability, environmental benefit, its natural by-product origin, transportation flexibility and diverse application, LPG plays a pivotal role in the transition towards a more secure, sustainable and competitive energy model...

Discussions: Wednesday, September 22, at 6 PM and Thursday, September 23, at 1 PM in the Sunken Lounge of the DC Nomar and Professor Pedro An Honor Council Academic Trial Released Fall 2004 Introduction: Nomar was a student in Professor Pedro’s class. Nomar handed in a paper to Professor Pedro with several sections that Professor Pedro thought were not Nomar’s own work. After confronting Nomar ...

Two semiarboreal skinks (Mabuya) are narrowly sympatric in the Kalahari desert, whereas two terrestrial species are broadly sympatric both with one another and with the semiarboreal species. We attempt to discern reasons for these differing distributional patterns. The narrow zone of sympatry of the semiarboreal species is partially congruent with zones of habitat change (rainfall and vegetatio...

6 Pathogen propagation is a fundamental process that takes place through host contact networks. 7 While it has been possible to characterize contact networks of several human infectious diseases 8 (e.g., sexual contacts for HIV, physical proximity for measles), logistical difficulties and the high costs 9 of data collection makes network modeling of infectious diseases in animal populations par...

Madagascar is a biodiversity hotspot threatened by habitat loss, which is detrimental to the future survival of forest-dwelling herpetofauna. For conservation purposes, it is essential to determine how species respond to different types of anthropogenic habitat alteration. We conducted standardized field surveys (a variation of visual encounter survey) to assess species richness, abundance and ...

Ever since Corlett and Hague (1953), it has been understood that it tends to be optimal on second-best grounds to (relatively) tax complements to leisure and subsidize substitutes because doing so helps to offset the distorting effect of taxation on labor supply. Yet in the context of simultaneous optimization of a nonlinear income tax and commodity taxes, Atkinson and Stiglitz (1976) claim to ...

The paper discusses the functional design and the embodiment design of Epi.q Lizard, which is the last version of the Epi.q ground mobile robots family. Epi.q robots are equipped with underactuated stepping triple wheel locomotion units with epicyclical gearings, capable of switching between wheeled and legged locomotion without control intervention, depending on the dynamic condition of the ve...
