The parasitic nematode Ancylostoma ceylanicum is common in dogs, cats and humans throughout Asia, inhabiting the small intestine and possibly leading to iron-deficient anaemia in those infected. It has previously been discovered in domestic dogs in Australia and this is the first report of A. ceylanicum in wild canids. Wild dogs (dingoes and dingo hybrids) killed in council control operations (...
Managing reproduction for Canidae species is a challenge for zoological institutions and wildlife sanctuaries. There are four basic options for contraception: separation of sexes, surgical procedures, immunological and hormonal methods. Animal managers face potential challenges for each option, and advantages and disadvantages should be taken into consideration when making a decision. This pape...
Mating with close kin can lead to inbreeding depression through the expression of recessive deleterious alleles and loss of heterozygosity. Mate selection may be affected by kin encounter rate, and inbreeding avoidance may not be uniform but associated with age and social system. Specifically, selection for kin recognition and inbreeding avoidance may be more developed in species that live in f...
One way to investigate the evolution of cognition is to compare the abilities of phylogenetically related species. The domestic dog (Canis lupus familiaris), for example, still shares cognitive abilities with the coyote (Canis latrans). Both of these canids possess the ability to make psychophysical "less/more" discriminations of food based on quantity. Like many other species including humans,...
Specimens of Filaroides milksi Whitlock, 1956 removed from the same lung tissue as were the type specimens were re-examined. Because of morphological features similar to those found in the genus Andersonstrongylus Webster, 1978 and inconsistent with those in Filaroides van Beneden, 1850, F. milksi is removed from the latter and placed in Andersonstrongylus as A. milksi (Whitlock, 1956). All ava...
