Infectious diseases in wild animals have been increasing as a result of their habitat alterations and closer contact with domestic animals. Canine distemper virus (CDV) has been reported in several species of wild carnivores, presenting a threat to wildlife conservation. We described the first case of canine distemper virus infection in lesser grison (Galictis cuja). A free-ranging individual, with no visible clinical sigs, presented sudden death after one day in captivity. Molecular diagnosis for CDV infection was performed using whole blood collected by postmortem intracardiac puncture, which resulted positive. The virus phylogeny indicated that domestic dogs were the probable source of infection.

Body weights of free-ranging and captive juvenile Richardson's ground squirrels (Spermophilus richardsoni) were determined at regular intervals during the nonhibernating season. Animals in captivity gained weight at a faster rate and to a greater extent than those in their natural habitat. Attainment of maximum weights in captive ground squirrels was associated with a reduction in food intake and could not be related to food availability, a change in temperature, or in photoperiod.

It is important to understand how wild-caught animals may respond to captivity, and whether their behaviours in captivity are reflective of their wild counterparts. We observed the behaviour of wild-caught western grey kangaroos (Macropus fuliginosus) and red kangaroos (Osphranter rufus; formerly M. rufus) that were transferred to a large naturally vegetated enclosure. Observations were made on the first day of captivity and again after 7–10 days, and were compared with the behaviour of free-living kangaroos at the same locality and over the same period. We quantified feeding, moving, grooming and non-alert behaviours. Of these, grooming was higher in captive kangaroos than in free-living animals on the first day of captivity only, and was no different to that of wild animal by 7–10 days’ captivity. Such self-directed behaviour may be indicative of heightened distress for kangaroos on the first day of captivity, but it may also be indicative of grooming to eliminate contamination of human smells or debris following capture by darting and recovery. Overall, our findings indicate that after a short period of captivity, wild-caught kangaroos adjust to a novel environment relatively quickly, and animals from each species showed behaviour patterns comparable with free-ranging counterparts within 7–10 days after capture and captivity.

The aim of the current study was to investigate the exposure of captive wild felids to various infectious pathogens using serological and molecular methods. One hundred and fifty-nine neotropic felids and 51 exotic felids from 28 captive settings in Brazil were tested. While antibodies against Feline parvovirus and Feline coronavirus (FCoV), Feline calicivirus and Bartonella spp. were frequently detected by serologic tests, antibodies against Felid herpesvirus 1 or infection with hemotropic mycoplasmas were less prevalent. Serologic evidence of exposure to Ehrlichia spp., Feline immunodeficiency virus, and Feline leukemia virus (FeLV) was detected rarely, and infections with FeLV, Ehrlichia spp., and Cytauxzoon spp. were found infrequently. The detected Bartonella sequence was molecularly similar to B. koehlerae and B. henselae; for Cytauxzoon, the sequence resembled those from domestic cats. No Anaplasma phagocytophilum and Theileria spp. infections were detected. The positive test results varied significantly among different facilities and species. Additionally, FCoV seropositivity was more prevalent in captivity than in free-ranging populations. Results suggest that testing is appropriate prior to relocation of felids.

Body mass, body composition, and water transfer rates were determined over a continuous 2-year period in nine free-ranging Sitka black-tailed deer (Odocoileus hemionus sitkensis). Body masses showed a cyclical pattern, declined 14 – 31% between October and March, and were best described by a five-parameter, biologically based regression model. The amount of mass lost by black-tailed deer over winter depended on the peak body mass attained during fall. During winter, animals used 70 – 82% of their body fat and 10 – 15% of their protein reserves. Body fat was preferentially mobilized at rates 2.3 – 11.6 times higher than protein. Because of the higher energy content of fat, fat accounted for 83 – 92% of the catabolized energy. Water transfer rates varied seasonally with average summer values approximately four times those of winter; lactating deer had significantly higher rates of water transfer than nonlactating animals. Seasonal changes in all of the above parameters for wild deer were greater than those for eight deer of the same age in captivity.

The mobility of the primate tongue allows for the manipulation of food, but, in addition, houses both general sensory afferents and special sensory end organs. Taste buds can be found across the tongue, but the ones found within the fungiform papillae on the anterior two thirds of the tongue are the first gustatory structures to come into contact with food, and are critical in making food ingestion decisions. Comparative studies of both the macro and micro anatomy in primates are sparse and incomplete, yet there is evidence that gustatory adaptation exists in several primate taxa. One is the distally feathered tongues observed in non-destructive nectar feeders, such as Eulemur rubriventer. We compare both the macro and micro anatomy of three lemurid species who died of natural causes in captivity. We included the following two non-destructive nectar feeders: Varecia variegata and Eulemur macaco, and the following destructive flower feeder: Lemur catta. Strepsirrhines and tarsiers are unique among primates, because they possess a sublingua, which is an anatomical structure that is located below the tongue. We include a microanatomical description of both the tongue and sublingua, which were accomplished using hematoxylin–eosin and Masson trichrome stains, and scanning electron microscopy. We found differences in the size, shape, and distribution of fungiform papillae, and differences in the morphology of conical papillae surrounding the circumvallate ones in all three species. Most notably, large distinct papillae were present at the tip of the tongue in nectar-feeding species. In addition, histological images of the ventro-apical portion of the tongue displayed that it houses an encapsulated structure, but only in Lemur catta case such structure presents cartilage inside. The presence of an encapsulated structure, coupled with the shared morphological traits associated with the sublingua and the tongue tip in Varecia variegata and Eulemur macaco, point to possible feeding adaptations that facilitate non-destructive flower feeding in these two lemurids.

However despotic a social group may be, managing conflicts of interest is crucial to preserve group living benefits, mainly based on cooperation. In fact, in despotic groups post-conflict management via reconciliation (the first post-conflict reunion between former opponents) can occur, even if at variable levels. In the despotic Lemur catta reconciliation was reported in one out of four captive groups. We used this species as a model to understand what variables influence the occurrence of the reconciliation in despotic groups. We analyzed 2339 PC-MC collected on eight groups (five in the Berenty forest, Madagascar; three hosted at the Pistoia Zoo, Italy). Since Lemur catta is characterized by rigid female dominance but show female-female coalitionary support, we expected to find reconciliation in the wild, other than in captivity. Consistently, we found the phenomenon to be present in one captive group and two wild groups, thus providing the first evidence of the presence of reconciliation in wild Lemur catta. Being this species a seasonal breeder (with mating occurring once a year), we expected that the season more than other variables (wild/captivity setting, rank, or individual features) would influence reconciliation levels. Via GLMM we found that the season was indeed the only variable significantly explaining reconciliation rates, lowest during mating and highest during the pregnancy period. We posit that reconciliation can be present in despotic species but not when the advantages of intra-group cooperation are annihilated by competition, as it occurs in seasonal breeders when reproduction is at stake. By comparing our results with literature, we conclude that in despotic social groups in which coalitions are observed, the right question is not if but when reconciliation can be present.
