Veterinary parasitology has always been considered to be relevant and interesting by the Danish veterinary students. Students have to acquaint themselves with many new, small creatures with complicated and varied life cycles and with intricate Latin names that are difficult to pronounce, as only a few parasites have Danish names. In our veterinary curriculum, zoology has disappeared as a discipline, and parasitology has gradually moved from the third year to the beginning of the second year, which implies that, for example, pathology and pharmacology are "unknown fields"...

Zoological institutions play an important role in promoting the goals of the One Health movement. We launched the Institute for Conservation Medicine (ICM) at the Saint Louis Zoo in 2011 to advance the goals of One Health. In 2016, we distributed a survey to Zoo members to evaluate member awareness and understanding of One Health and to provide direction for future communication and actions from the ICM. We hypothesized that Zoo members would be aware of One Health and care about infectious disease issues. Survey results showed Zoo members primarily cared about chronic, non-infectious diseases and their associated economic costs, with participants ranking their top three health issues of concern for humans as nutrition/obesity/diet (49%), costs of health care (48%), and cancer (37%)...

The Amur leopard ( Panthera pardus orientalis) is one of the most critically endangered leopards on the International Union for the Conservation of Nature red list. The primary objective of this retrospective study was to identify common and significant causes of morbidity and mortality in the North American Amur leopard zoo population. This information provides insights that contribute to their improved care, health, and medical management and, ultimately, affects the sustainability of this leopard subspecies in the wild...

Hormonal contraception is being increasingly used to manage captive animals in zoological collections. Many of the animals placed on contraception are of genetic importance within captive breeding programs; therefore, it is imperative that the application of contraceptive products minimize potential side effects and facilitate a return to fertility if required. Deslorelin acetate implants (Suprelorin®) are one example of a hormonal contraceptive that is frequently used in captivity as they are easy to use and effective in most species...

Published reports of neoplasms in Thomson's gazelles ( Eudorcas thomsonii) are very rare, but thyroid tumors were the most common neoplasm of this species, accounting for 12% of reported pathologies in a 1998-2012 retrospective study of cases submitted for histologic review of grossly enlarged thyroid glands. This report describes the histological and immunohistochemical characteristics of thyroid neoplasms in 10 Thomson's gazelles from five different zoological collections. Neoplasms were submitted as biopsies from six gazelles or collected during necropsy from four gazelles...

Gastrointestinal parasites are commonly reported in wild birds, but transmission amongst avifauna in zoological settings, and between these captive birds and wild birds in surrounding areas, remains poorly understood. A survey was undertaken to investigate the occurrence of gastrointestinal parasites in captive and free-ranging birds at Bristol Zoo Gardens between May and July 2016. A total of 348 fecal samples from 32 avian species were examined using the Mini-FLOTAC flotation method. Parasites were detected in 31% (45/145) of samples from captive birds and in 65...

Two captive Bocourt water snakes ( Subsessor bocourti) presented with chronic white skin lesions on their heads; Ophidiomyces ophiodiicola was identified by culture and polymerase chain reaction (PCR) in skin scrapings from both snakes. Histopathology performed in one Bocourt water snake revealed fungal hyphae in epidermal structures of lesions. One Pueblan milk snake ( Lampropeltis triangulum campbelli) from the same zoologic institution presented with yellow crusts and white blisters on its body, from which O...

Two novel and distinct Brucella strains were recovered from 5 of 10 adult, sex undetermined, captive waxy tree frogs ( Phyllomedusa sauvagii) and two of five adult, sex undetermined, captive Colorado river toads ( Incilius alvarius) held in a zoologic collection with clinical and pathologic findings of bacterial disease. These amphibians originated from three separate private breeding facilities over several years and exhibited disease 9-49 mo following release from quarantine. Common presenting signs were vague but included focal abscessation, weight loss, change in coloration, anorexia, and decreased perching...

This article highlights the relationship between walruses and humans in and around the North Water polynya in a long-term perspective. The present study draws on a combination of biological, archaeological, archaeo-zoological, historical, and ethnographic sources covering the period from the 8th century AD to the late 20th century. The study demonstrates that the walrus was an important resource of meat, blubber, and other products throughout all the studied periods, if always supplemented by other kinds of game...

In this paper, I discuss the development and use of images employed by the Dresden Royal Museum for Zoology, Anthropology and Ethnography to resolve debates about how to use visual representation as a means of making ethnographic knowledge. Through experimentation with techniques of visual representation, the founding director, A.B. Meyer (1840-1911), proposed a historical, non-essentialist approach to understanding racial and cultural difference. Director Meyer's approach was inspired by the new knowledge he had gained through field research in Asia-Pacific as well as new forms of imaging that made highly detailed representations of objects possible...

A major focus in zoology is to understand the phenotypic responses of animals to environmental variation. This is particularly important when dealing with ectotherms in a thermally heterogenous environment. We measured body temperatures of a free-ranging, medium sized temperate reptile, the tuatara, Sphenodon punctatus, to investigate its thermal opportunities and the degree to which the animal actively regulates its body temperature. We found high variation in body temperature between individuals, but this variation could not be attributed to sex or body size...

Evolutionary computational methods have adopted attributes of natural selection and evolution to solve problems in computer science, engineering, and other fields. The method is growing in use in zoology and ecology. Evolutionary principles may be merged with an agent-based modeling perspective to have individual animals or other agents compete. Four main categories are discussed: genetic algorithms, evolutionary programming, genetic programming, and evolutionary strategies. In evolutionary computation, a population is represented in a way that allows for an objective function to be assessed that is relevant to the problem of interest...

Non-invasive imaging techniques like X-ray computed tomography have become very popular in zoology, as they allow for simultaneous imaging of the internal and external morphology of organisms. Nevertheless, the effect of different staining approaches required for this method on samples lacking mineralized tissues, such as soft-bodied invertebrates, remains understudied. Herein, we used synchrotron radiation-based X-ray micro-computed tomography to compare the effects of commonly used contrasting approaches on onychophorans - soft-bodied invertebrates important for studying animal evolution...

Eastern grey kangaroos (Macropus giganteus) younger than 19 months at Kanazawa Zoological Gardens, Japan, frequently died of enteritis. The main cause of death was coccidiosis. This study aimed to reveal retrospectively the clinical features of enteritis and factors contributing to its high occurrence. In addition, haematological and serum biochemical parameters in kangaroos younger than 24 months were analyzed. The findings suggested that enteritis occurrence was higher in 10- to 12-month-old kangaroos than other ages and during seasons with high temperature and humidity than during seasons with low temperature and humidity...

Bird feathers have been proven to be reliable indicators of metal exposure originating from contaminated food and polluted environments. The concentrations of 15 essential and non-essential metals were investigated in African penguins (Spheniscus demersus) feathers from a Northwestern Italian zoological facility. These birds are exclusively fed with herring from the northeast Atlantic Ocean. Certain elements, such as Hg and Cd, reflected the bioaccumulation phenomena that occur through the marine food chain...

Narwhals (Monodon monoceros) are at the top of the Arctic food web and therefore might biomagnify high total mercury (Hg) concentrations in organs and tissues. The aim of this study was to determine histopathology and Hg concentrations in liver and kidneys from 15 North East Greenland narwhals (3 subadult females, 8 adult females, 3 subadult males, and 1 adult male) and compare data with previous observations of 12 North West Greenland specimens (1 subadult female, 4 adult females, 1 subadult male, and 6 adult males)...
