A need exists for research that contributes to estimating the risk factors associated with the management of outdoor cats (Felis silvestris catus) and addresses the lack of such surveys in Brazil and other Latin American countries. With this in mind we aimed to: i) identify the causal factors affecting the practice of owners allowing their cats to roam freely and; ii) evaluate potential welfare risks associated with the allowance of outdoor access, based on cat owners' reports. An online questionnaire consisting of 25 questions was answered by 8,485 Brazilian cat owners and logistic regression models used to obtain odds ratios. A number of the factors significantly related to owners allowing their cats to have outdoor access were unneutered cats, the manner in which the cat was acquired, residence in rural areas, the number of cats owned, the presence of other pets in the house, younger owner age, owner declaration of not being responsible for the cat, owner perception about the role of the cat in the house, owner knowledge about cats' potential for transmitting diseases, a lack of knowledge about zoonoses, and a lack of knowledge regarding toxoplasmosis. The practice of allowing outdoor access was associated with significantly higher odds of owners reporting several welfare issues, such as frequent flea contamination, sporotrichosis, going missing, poisoning, mistreatment, and accidents. We conclude that the practice of allowing outdoor access, as reported by 37.1% of our respondents, may result in risks to feline welfare. Increasing public awareness through campaigns that highlight the risks associated with outdoor access would improve feline management practices and welfare.

<p>Free-ranging reindeer on the Seward Peninsula in western Alaska are rounded up from late May to early July and antlers are removed. We used data collected from 1987 to 1997 to determine how velvet antler weights of males and females varied with age, year, reproductive status, Julian date, and body weight. Male antler weights increased with age up to age five years, and were lower in castrates than in bulls. There was a significant positive relationship between body weight and antler weight in both sexes. Female antler weights increased with age until at least age nine. Lactating females had lower antler weights than non-lactating females, but this effect is better explained by differences in body weight. Antler weight of individual reindeer at age two years was better predicted by their antler weights as yearlings than their body weight as yearlings.</p>

Horses are a gregarious species with strong social bonds between individuals and when under free-ranging conditions, form family bands or herds (Tyler, 1979; Wells and Goldschmidt-Rothschild, 1979). Each herd contains small bands of roughly 3 adult horses (1 stallion, 2-3 mares) plus their most recent offspring (Linklater et al., 1999). There are also bachelor groups composed of males that are either too young for their own harems, or can no longer defend the harems they once had (Waring, 1983). As horses live in groups they have evolved a complex behaviour repertoire in order to communicate. Mutual grooming and play are two such behaviours that have been widely studied in both domestic and feral horses, however the results from studies on their influencing factors have been contradictory. Mutual grooming has the obvious function of coat care and parasite removal; moreover, it has also been implicated in forming and maintaining bonds between horses in a herd (Waring, 1983).

ABSTRACT Recent serological and molecular surveys of different primate species allowed the characterization of several Kaposi's sarcoma-associated herpesvirus (KSHV) homologues in macaques, African green monkeys, chimpanzees, and gorillas. Identification of these new primate rhadinoviruses revealed the existence of two distinct genogroups, called RV1 and RV2. Using a degenerate consensus primer PCR method for the herpesvirus DNA polymerase gene, the presence of KSHV homologues has been investigated in two semi-free-ranging colonies of eight drill (Mandrillus leucophaeus), five mandrill (Mandrillus sphinx), and two hybrid (Mandrillus leucophaeus-Mandrillus sphinx) monkeys, living in Cameroon and Gabon, Central Africa. This search revealed the existence of not only two distinct KSHV homologues, each one belonging to one of the two rhadinovirus genogroups, but also of two new betaherpesvirus sequences, one being close to cytomegaloviruses and the other being related to human herpesviruses 6 and 7 (HHV-6 and -7). The latter viruses are the first simian HHV-6 and -7 homologues identified to date. These data show that mandrill and drill monkeys are the hosts of at least four novel distinct herpesviruses. Moreover, mandrills, like macaques and African green monkeys, harbor also two distinct gamma-2 herpesviruses, thus strongly suggesting that a second gamma-2 herpesvirus, belonging to the RV2 genogroup, may exist in humans.

Free-ranging prawns showed substantial spatial and temporal variation in PFOS concentrations, most likely driven by behavioural and physiological factors.
