“…Laboratory data are increasingly utilized in programs involving captive breeding and translocations, which are important management tools for conservation programs. Thorough and accurate health assessment of animals in these programs is critical, and laboratory evaluation is integral to health assessments prior to translocation . However, for meaningful laboratory result interpretation, species‐ specific reference intervals (RI) from healthy individuals must be first established .…”

Background The Tasmanian devil (Sarcophilus harrisii) is a carnivorous marsupial threatened with extinction by a fatally infectious cancer known as devil facial tumor disease (DFTD). Conservation efforts including captive breeding and island translocations are underway to address this threat. Objectives The objectives of this study were to determine hematologic and serum biochemical reference intervals (RI) to aid in health assessment of Tasmanian devils, and to examine seasonal, sex, reproductive status and age variations. Methods We collected jugular blood samples from individual wild Tasmanian devils at 2 different locations over a 2‐year period to determine hematologic and serum biochemical RI by nonparametric methods using the central 0.95 fraction. Results A total of 307 blood samples were collected from 187 devils. Significant age differences were found for ALP, CK, cholesterol, calcium, phosphate, albumin, globulins, albumin: globulin ratio, and glucose. Significant differences between sexes were observed for AST, creatinine, and potassium. Significant seasonal or reproductive status variation in adult males or breeding females were observed for PCV, HGB, RBC, MCHC, MCH, MCV, neutrophils and lymphocytes, fibrinogen, total plasma protein, AST, ALP, ALT, GLDH, bilirubin, urea, calcium, chloride, total protein, albumin, A:G, and glucose. Conclusions Many of the differences observed between subgroups can be explained by growth requirements, reproductive demands, and seasonal effects on activity. This study has determined comprehensive RI for the Tasmanian devil, which will be used to assess animals targeted for captive breeding and translocations, or affected by DFTD.

“…Less known are the reintroduction efforts of gazelles ( G. gazella and Gazella subgutturosa marica ) in Saudi Arabia (Ibex Reserve, Mahazat as‐Said, Uruq Bani Ma'Arid; Dunham, 1995, 1997 a , b , 2001). Repatriation programmes should be accompanied by adequate monitoring activities (Beck et al ., 1994; Soorae & Seddon, 1998; Kock, Soorae & Mohammed, 2007). This, however, represents a problem, because released individuals can be followed when fitted with radio collars, but uncollared offspring are often barely detectible (Dunham, 1997 c , 2001).…”

Mountain gazelle Gazella gazella in Saudi Arabia are listed as 'vulnerable' by the IUCN. At present, the species' survival is secured by extensive captive-breeding programmes and reintroductions into protected areas. Two reintroduction attempts (Ibex Reserve and Uruq Bani Ma'Arid protected areas) in Saudi Arabia have been undertaken in the past two decades. Post-monitoring of released individuals is essential for the success of such reintroduction programmes; however, cryptic species like mountain gazelles are extremely difficult to observe directly. As radio-tracking is a cost-intensive and invasive post-monitoring technique, we asked: how can reintroduced or remnant pockets of natural gazelle populations be monitored indirectly? Here, we propose the use of latrine mapping as an effective, cost-efficient and non-invasive tool to survey the social organization of reintroduced mountain gazelles as an indicator for repatriation success. In this study, we used released radio-collared animals to characterize the spatial distribution of latrines within female group home ranges. Distance to the next latrine, latrine size, as well as numbers of fresh faecal pellet groups per latrine or presence of urination marks were used as dependent variables for step-wise backward multiple regressions and were correlated with various ecological factors. Most dependent variables were correlated with distance or direction from the nearest tree, but not indicative of home-range cores. Only latrine densities were distinctly higher in core areas of female group home ranges, and no pattern of peripheral marking was detected. Hence, latrine density is a good indicator of home-range use in female group home ranges. Mapping latrines and determining latrine densities are therefore the methods of choice to survey mountain gazelle populations.

“…Minimization of risk for disease transmission must be considered during reintroduction programs (Viggers et al, 1993;Woodford and Rossiter, 1994), and examination of hematologic and serum biochemical parameters complements clinical assessments during health surveys of wild animal populations (Kock et al, 2007). Translocation has featured in management of the western ringtail possum, Pseudocheirus occidentalis, which is listed as threatened under the Commonwealth of Australia's Environment Protection and Biodiversity Conservation Act, 1999 (Department of the Environment, Water, Heritage and the Arts, 2009) and by the International Union for the Conservation of Nature (IUCN, 2009).…”

ABSTRACT:Health screening of animals before translocation is important to minimize the risk of pathogen transmission between sites and species. Reintroduction has been incorporated into management of the endangered western ringtail possum (Pseudocheirus occidentalis) to mitigate for habitat loss within the species' core range in southwestern Australia. Between November 2005 and March 2008 we screened 47 wild and 24 captive P. occidentalis and 68 sympatric common brushtail possums (Trichosurus vulpecula hypoleucus) for infectious diseases that might compromise possum survival or fecundity at translocation sites. We found no evidence that infectious disease limits translocation success, and neither possum species showed evidence of infection with Salmonella spp., Toxoplasma gondii, Leptospira spp., or Chlamydophila spp. Antigen of Cryptococcus gattii was detected in one T. v. hypoleucus but was not of pathologic significance. Hematologic and serum biochemical reference ranges were determined for 81 wild and 24 captive P. occidentalis. Site differences were identified for red blood cell count, hemoglobin, albumin, urea, and globulin, suggesting that habitat quality or nutrient intake may vary among sites. Differences between wild and captive values were found for several parameters. These data are useful for health evaluations of injured P. occidentalis and the future monitoring of wild populations.
