In recent years, there have been two parallel research paths for developing advanced traffic signal systems. Real-time traffic adaptive system research, supported largely by the United States Department of Transportation (USDOT) and smaller scale closed loop systems developed primarily by traffic signal system vendors. Simulation models have been developed for evaluating USDOT supported project...

A recent study has inferred that the red fox (Vulpes vulpes) is now widespread in Tasmania as of 2010, based on the extraction of fox DNA from predator scats. Heuristically, this inference appears at first glance to be at odds with the lack of recent confirmed discoveries of either road-killed foxes--the last of which occurred in 2006, or hunter killed foxes--the most recent in 2001. This paper...

BACKGROUND Comparative phylogeography links historical population processes to current/ecological processes through congruent/incongruent patterns of genetic variation among species/lineages. Despite high biodiversity, India lacks a phylogeographic paradigm due to limited comparative studies. We compared the phylogenetic patterns of Indian populations of jungle cat (Felis chaus) and leopard cat...

This review focuses on the striking differences in the patterns of transcription and translation in somatic and spermatogenic cells in mammals. In early haploid cells, mRNA translation evidently functions to restrict the synthesis of certain proteins, notably protamines, to transcriptionally inert late haploid cells. However, this does not explain why a substantial proportion of virtually all m...

Domestic dogs (Canis lupus familiaris) have been in contact with humans for thousands of years, playing an important role societies. Nonetheless, the lack responsible ownership has contributed to transition from companion free-ranging or feral that can be reservoirs zoonotic parasites. Our goal was identify intestinal parasites a Mexican Protected Area. A total 132 scat samples were collected a...

Abstract Keystone predators can impact many prey species, including those that are endangered. A requisite to assess the have on different populations is identify species being consumed in types of communities, while accounting for possible seasonal variation consumption. Here we used analysis North American river otter (Lontra canadensis) scat otters their populations, particularly endangered ...

Abstract Many mammalian species communicate via olfactory communication placed at particular locations. The majority of these studies focused on intraspecific communication. More recently, have also investigated interspecific and recorded prey animals sniffing cues left by predators investigating or counter-marking other predator species. purpose exchanging within a community is little understo...

Top-predators contribute to ecosystem resilience, yet individuals or populations are often subject to lethal control to protect livestock, managed game or humans from predation. Such management actions sometimes attract concern that lethal control might affect top-predator function in ways ultimately detrimental to biodiversity conservation. The primary function of a predator is predation, whic...
