One way to gain insights into personality evolution is by comparing the personality structures of related species. We compared the personality structure of 240 wild white-faced capuchin monkeys to the personality structure of 100 captive brown capuchin monkeys. An ancillary goal was to test the degree to which different personality questionnaires yielded similar personality dimensions. Both species were rated on a common set of 26 antonym pairs. The brown capuchin monkeys were also rated on the 54-item Hominoid Personality Questionnaire. Our cross-species comparisons revealed 3 personality dimensions-Assertiveness, Openness, and Neuroticism-shared by brown and white-faced capuchins, suggesting that these dimensions were present in the common ancestor of these species. Our comparison of the dimensions derived from the antonym pairs and the Hominoid Personality Questionnaire revealed that three common dimensions were identified by both questionnaires. In addition, the dimension Attentiveness was only identified using the Hominoid Personality Questionnaire. These results indicate that major features of capuchin personality are conserved and that the structure of some traits, such as those related to focus, persistence, and attention, diverged. Further work is needed to identify the evolutionary bases that led to the conservation of some dimensions but not others. (PsycINFO Database Record

Genes of the vertebrate major histocompatibility complex (MHC) are crucial to defense against infectious disease, provide an important measure of functional genetic diversity, and have been implicated in mate choice and kin recognition. As a result, MHC loci have been characterized for a number of vertebrate species, especially mammals; however, elephants are a notable exception. Our study is the first to characterize patterns of genetic diversity and natural selection in the elephant MHC. We did so using DNA sequences from a single, expressed DQA locus in elephants. We characterized six alleles in 30 African elephants (Loxodonta africana) and four alleles in three Asian elephants (Elephas maximus). In addition, for two of the African alleles and three of the Asian alleles, we characterized complete coding sequences (exons 1-5) and nearly complete non-coding sequences (introns 2-4) for the class II DQA loci. Compared to DQA in other wild mammals, we found moderate polymorphism and allelic diversity and similar patterns of selection; patterns of non-synonymous and synonymous substitutions were consistent with balancing selection acting on the peptides involved in antigen binding in the second exon. In addition, balancing selection has led to strong trans-species allelism that has maintained multiple allelic lineages across both genera of extant elephants for at least 6 million years. We discuss our results in the context of MHC diversity in other mammals and patterns of evolution in elephants. © Springer-Verlag 2009.

Frog virus 3 (FV3) and FV3-like viruses are members of the genus Ranavirus (family Iridoviridae) and are becoming recognized as significant pathogens of eastern box turtles (Terrapene carolina carolina) in North America. In July 2011, 5 turtles from a group of 27 in Maryland, USA, presented dead or lethargic with what was later diagnosed as fibrinonecrotic stomatitis and cloacitis. The presence of FV3-like virus and herpesvirus was detected by polymerase chain reaction (PCR) in the tested index cases. The remaining 22 animals were isolated, segregated by severity of clinical signs, and treated with nutritional support, fluid therapy, ambient temperature management, antibiotics, and antiviral therapy. Oral swabs were tested serially for FV3-like virus by quantitative real-Time PCR (qPCR) and tested at day 0 for herpesvirus and Mycoplasma sp. by conventional PCR. With oral swabs, 77% of the 22 turtles were FV3-like virus positive; however, qPCR on tissues taken during necropsy revealed the true prevalence was 86%. FV3-like virus prevalence and the median number of viral copies being shed significantly declined during the outbreak. The prevalence of herpesvirus and Mycoplasma sp. by PCR of oral swabs at day 0 was 55% and 68%, respectively. The 58% survival rate was higher than previously reported in captive eastern box turtles for a ranavirus epizootic. All surviving turtles brumated normally and emerged the following year with no clinical signs during subsequent monitoring. The immediate initiation of treatment and intensive supportive care were considered the most important contributing factors to the successful outcome in this outbreak. © Copyright 2016 by American Association of Zoo Veterinarians.

In 1960, the Golden lion tamarin Leontopithecus rosalia was almost extinct in the wild and the captive population, with poor reproduction and survival, was not well established. In the 1970s, after many improvements, the captive population began to grow and the Poço das Antas Biological Reserve was created to protect the species. In the 1980s, long-term research was begun on the demography and socio-ecology of the Golden lion tamarins, along with community environmental education and a reintroduction programme of captive-born animals (initially in the reserve, later in neighbouring private forests). About 30 zoos contributed the 146 captive-born reintroduced tamarins, and provided information on social behaviour, nutrition and health that was critical to developing reintroduction strategies. In 1994, threatened groups isolated in small fragments were rescued and translocated to a protected forest. Both programmes have been successful as measured by survival and reproduction after release, and both techniques have established growing populations. Although new threats (introduction of exotic primates) continue to challenge our efforts to preserve the species, there is no doubt of the success of almost 30 years of the Golden Lion Tamarin Conservation Programme. © 2012 The Authors.

Four Roller pigeons (Columba livia f. dom.) at the Philadelphia Zoo died suddenly. Necropsy examination revealed macroscopic hepatitis. Microscopically, the predominant lesions were in liver, characterized with necrosis and mixed cell inflammatory response. Sarcocystis calchasi-like schizonts and free merozoites were identified in liver. Transmission electron microscopy confirmed that schizonts were in hepatocytes. A few schizonts were in spleen. PCR using S. calchasi-specific primers confirmed the diagnosis. Neither lesions nor protozoa were found in brain and muscles. This is the first report of acute visceral S. calchasi-associated sarcocystosis in naturally infected avian hosts.

She's Colo, the nation's oldest living gorilla, and she turned 60 on Thursday at the Columbus Zoo and Aquarium. Colo was the first gorilla in the world born in a zoo and has surpassed the usual life expectancy of captive gorillas by two decades. Her longevity is putting a spotlight on the medical care, nutrition and up-to-date therapeutic techniques that are helping lengthen zoo animals' lives. "Colo just epitomizes the advances that zoos have made, going all the way back to her birth at Columbus," said Dr. Tom Meehan, vice president for veterinary services at Chicago's Brookfield Zoo and veterinary adviser to a national gorilla species survival plan. The changes also mean more animals living with the normal aches and pains of growing older. Today, zoo veterinarians regularly treat animals for heart and kidney disease, arthritis, dental problems and cancer. Hundreds of people gathered at the zoo Thursday to see Colo, singing "Happy Birthday" moments before the gorilla ambled into an enclosure decorated with multicolored construction paper chains and filled with cakes such as squash and beet and cornbread with mashed potato parsley frosting. Among the first in line was Pam Schlereth of Columbus, who at 63 was just a little girl when her father brought her to see the newborn Colo in a gorilla incubator in 1956. "It's a tribute to the zoo that she's alive at 60 years old," Schlereth said. Colo represents so much to the zoo, Tom Stalf, president of the zoo, told the crowd. "It's all about connecting people and wildlife," he said. Colo is one of several elderly gorillas around the country. The oldest known living male gorilla, Ozzie, is 55 years old and lives at the Atlanta Zoo, which has a geriatric gorilla specialty. At Seattle's Woodland Park Zoo, staff members use acupuncture, massage, laser therapy, and heat and joint supplements to help Emma, a 13-year-old rabbit. At the National Zoo in Washington, Shanthi, a 42-year-old Asian elephant with arthritis, receives osteoarthritis therapy and was recently fitted with specially crafted front foot boots to help her feet heal as medications are applied. In Oakland, California, Tiki, a 27-year-old giraffe and one of the oldest in the nation, gets foot care, massage therapy, acupuncture and chiropractic care, along with traditional veterinary medicine. Gao Gao, a 26-year-old male panda at the San Diego Zoo with a heart condition, periodically undergoes cardiac ultrasounds. "Geriatrics is probably one of our most common medical challenges that we face in a zoo situation," said Dr. Keith Hinshaw, director of animal health at the Philadelphia Zoo. "So pretty much anything that you could imagine would happen with an older person is going to happen eventually with any animal." That's up to and including medication: JJ, a 45-year-old orangutan at the Toledo Zoo, is on the human heart medicines carvedilol and Lisinopril, along with pain and orthopedic medications. He also takes Metamucil. Colo, a western lowland gorilla, holds several other records. On her 56th birthday in 2012, she exceeded the record for longest-lived gorilla. On Thursday, she surpasses the median life expectancy for female gorillas in human care (37.5 years) by more than two decades. Coldilocks, a 36-year-old polar bear at the Philadelphia Zoo and considered the oldest polar bear in the U.S. The bears' typical lifespan in captivity is 23 years. The zoo says treating her early for kidney disease appears to have helped prolong her life. Elly, an eastern black rhino at the San Francisco Zoo estimated to be 46 years old, is the oldest of her species in North America. She has had 14 calves, and her offspring have produced 15 grandchildren, 6 great-grandchildren and 1 great-great-grandchild. Packy, an Asian elephant at the Oregon Zoo, and at 54, the oldest male of his species in North America. The zoo says Packy, born in 1962, became the first elephant to be born in the Western Hemisphere in 44 years. Nikko, a 33-year-old snow monkey at the Minnesota Zoo, the oldest male snow monkey in North America. Little Mama, a chimpanzee living at Lion Country Safari in Loxahatchee, Florida, with an estimated age in her late 70s. She takes allergy medicine, iron supplements and omega 3 multivitamins, and has been trained to accept a nebulizer treatment for coughing.

Objectives Maximum ingested food size (Vb) is an empirically tested performance variable that can shed light on feeding energetics and adaptation in the masticatory system. Until now, this variable had been tested in strepsirrhines alone among primates. Here, we present the first data on Vb in a broad sample of anthropoid primates and describe scaling patterns. Materials and Methods Vb data on anthropoids were collected under captive conditions at the Philadelphia Zoo and compared with published data on strepsirrhines. Data on Vb were scaled against individual body mass and were compared with experimentally determined toughness and stiffness values for the test foods. Results Unlike in strepsirrhines, where essentially Vb scales isometrically with body mass, Vb in anthropoids scales with negative allometry. There is a significant effect of food material properties on Vb, although bite size in anthropoids varies less based on food properties than in strepsirrhines. Large folivorous strepsirrhines follow the anthropoid trend in bite size scaling, but large frugivorous ones take especially large bites. Discussion Negative scaling of bite size in the anthropoids sampled could be due to reduced adaptation for gape. Some early anthropoids likely evolved adaptations for maximizing mechanical advantage and fatigue resistance in the chewing muscles, resulting in reduced gape. This might have channeled them toward smaller bites of more-resistant foods and away from taking large bites. This might also be the case for some folivorous strepsirrhines.

Behaviour | Year: 2012

The aim of this study was to assess whether geographic variation in wild orangutan behavior reflected the presence of innovations or merely variation induced by genetic or environmental differences. We improved upon previous attempts to answer this question in three complementary ways. First, to minimize the possible effects of differences in genetic composition or the physical, biological and social environment, we compared a population of Bornean orangutans (Pongo pygmaeus wurmbii) at a new site (Sungai Lading) with that of an established site (Tuanan). These two populations were physically separated but showed high genetic similarity and occupied very similar habitats, leaving different innovation histories as the only plausible source of significant differences in their behavioral repertoires, if these were found. Second, we used identical observation methods and overlapping observers at both sites, deliberately attempting to record the full behavioral repertoire. Third, we introduced statistical techniques to reduce the likelihood of false absences. The results showed several behavior patterns unique to the new site, as well as the absence of several patterns observed at the established site, most of them satisfying the criteria previously proposed for recognizing innovations. We, thus, confirm that orangutans produce behavioral innovations, and conclude that the geographic method for identifying innovations in wild populations is a valid, albeit conservative, approach that can complement other techniques. Finally, the results also strongly support a cultural interpretation of geographic variation in orangutan behavior. © 2012 Koninklijke Brill NV, Leiden.
