The zoo-keeper's problem is to nd a shortest closed zoo-keeper's path starting at a point of the zoo and touching all cages. We present O(nlogn) algorithm for zoo-keeper's problem where n is the input size. The algorithm is based on a new data structure called the oodlight tree. We extend the approach to queries to nd a zoo-keeper's path with arbitrary nal point. We show that the zoo-keeper's q...

This study investigated behavioral activities (resting, moving, aggressive, social, and reproductive behavior) and fecal cortisol levels in 8 individually identified adult male blackbucks during periods of varying levels of zoo visitors (zero, low, high, and extremely high zoo visitor density). This study also elucidated whether zoo visitor density could disturb nonhuman animal welfare. This st...

background: toxoplasmosis, a worldwide zoonotic disease, is caused by toxo­plasma gondii . the distribution of genetic diversity of t. gondii in wild animals is of great importance to understand the transmission of the parasite in the environ­ment. however, little is known about t. gondii prevalence in wild animals and birds in china. methods: we conducted the genetic characterization of t. gon...

We study quasismooth hypersurfaces in P(a0, a1, a2, a3) of degree d < P 3 i=0 ai. All varieties are assumed to be complex, projective and normal.

We give four elementary examples of recursion that are reallife, non-trivial, more natural than the corresponding iterative approach, and do not involve any sophisticated algorithms, data structures, or mathematical problems. The examples are two forms of writing numbers in words, coalescing page references for an index, and finding unclosed begin blocks. My New Zoo, McGrew Zoo, will make peopl...

Sequences from complete mitochondrial cytochrome b genes of 34 tigers support the hypothesis that Sumatran tigers are diagnostically distinct from mainland populations. None of the latter, including Bengals, Siberians, or Indochinese tigers, were found to have fixed diagnostic characters. Phylogenetic analysis of these sequences confirms these results. Within the framework of a phylogenetic spe...

Petting zoos have been associated with E. coli O157:H7 outbreaks. Given the epidemiologic link between all cases and the farm, the hypothesis under joint investigation by the BCCDC and local health units was that the infections resulted from contact with the petting zoo animals. The purposes of this investigation were to verify the cause of the outbreak, determine the outbreak’s scope, and iden...

The study was carried out in zoo animals at Islamabad Zoo, Pakistan to know the prevalence of bovinetuberculosis. An overall prevalence of 3.3% was recorded in zoo animals with 3.6% in Bovidae, 3.2% inCervidae and 0% in Equidae families. The positive animals included spotted deer (1/3; 95% CI = 0.84,90.57), Chinkara gazella (1/5; 95% CI = 0.51, 71.64) and Blackbuck gazelle (1/30; 95% CI = 0.08,...

Given current extinction trends, the number of species requiring conservation breeding programs (CBPs) is likely to increase dramatically. To inform CBP policies for threatened terrestrial vertebrates, we evaluated the number and representation of threatened vertebrate species on the IUCN Red List held in the ISIS zoo network and estimated the complexity of their management as metapopulations. ...
