Conservation of species threatened with imminent extinction may require drastic measures that can be emotionally charged, politically unsavory, and legally challenging. A complex example relates to the decline of the island fox (Urocyon littoralis), endemic to the California Channel Islands, off the coast of the United States. The island fox exists as six subspecies, each found on a separate is...

Red foxes hunting small animals show a specific behaviour known as 'mousing'. The fox jumps high, so that it surprises its prey from above. Hearing seems to be the primary sense for precise prey location in high vegetation or under snow where it cannot be detected with visual cues. A fox preparing for the jump displays a high degree of auditory attention. Foxes on the prowl tend to direct their...

Abstract We examine the effect of a rent subsidy program, Rent Assistance, on the demand for rental housing in The Netherlands. Low-income households with a rent that exceeds a norm rent, but is smaller than a maximum rent are eligible fo...

This paper intends on obtaining the explicit solution of $$n$$ -dimensional anomalous diffusion equation in infinite domain with non-zero initial condition and vanishing at infinity. It is shown that this can be derived from parabolic integro-differential memory which kernel $$t^{-\alpha}E_{1-\alpha,1-\alpha}(-t^{1-\alpha})$$ , $$\alpha\in(0,1),$$ where $$E_{\alpha,\beta}$$ Mittag-Liffler funct...

We present a finite difference method for modeling the propagation of electrical waves in cardiac tissue using the cable equation with homogeneous Neumann boundary conditions. This method is novel in that it is derived by first discretizing the phase field method as described by Fenton, et al, then taking a limit to recover a sharp interface. Our method provides for exact voltage conservation (...

We study the distribution of first passage time for Levy type anomalous diffusion. A fractional Fokker-Planck equation framework is introduced. For the zero drift case, using fractional calculus an explicit analytic solution for the first passage time density function in terms of Fox or H-functions is given. The asymptotic behaviour of the density function is discussed. For the nonzero drift ca...

red foxes and golden jackals are the two most abundant wild carnivores of iran which have the ability to adopt a variety of habitats and human proximity. despite this, very few investigations on their helminth and none on their external parasites infections have been carried out in iran. between 2003 and 2004, a total of 79 jackals and 37 foxes were collected from 3 different climatic zones of ...

pachysentis canicola (meyer, 1931) is an acanthocephalan belonging to the class oligacanthorhynchida. these species parasitize canids and other carnivores as definitive hosts which are followed by ingestion of an infected arthropod as its biological intermediate host. we present here a natural occurrence of p. canicola in fox from iran with special attention to its morphological characteristics.
