Recent Projects

 

Individual genetic monitoring of white-tailed sea eagles
	This study uses individual DNA profiling to help monitor reintroduced populations of white-tailed sea eagles in Scotland.
Conservation genetics of scimitar-horned oryx
	The S-H oryx is critically endangered and subject to several captive breeding and reintroduction projects.  This work applies conservation genetic data to inform SHO population management.
Genetic identification of illegally traded ramin
	This project developed a simple genetic test for identifying wood products originating from CITES-listed ramin species.
Development of a Hen Harrier DNA profiling system for wildlife enforcement and conservation management
	Collaborators: A. Iyengar, M. Thomas (UCLAN), S. Downing (Wildlife Consultant) This project aims to develop DNA profiling techniques to allow the individual identification of Hen Harriers for use in bird persecution cases and Hen Harrier management.
Molecular ecology of golden eagles
	Monitoring golden eagle population turnover using non-invasive genetic sampling. Using DNA profiles to identify individual golden eagles, this project will examine the patterns of breeding success and dispersal of wild populations in Scotland. DNA is being collected from moulted feathers and mouth swabs.
Paternity identification Dorcas gazelle
	Effective captive population management requires accurate pedigree records in order to direct breeding maximise conservation of genetic diversity. This project used DNA profiling to identify paternity in Dorcas gazelle, allowing pedigree records to be verified.
Monitoring goshawk persecution using DNA
	This project aims to examine the different rates of turnover between persecuted and non-persecuted nest sites in the Scottish Borders. DNA profiling of goshawks will enable individual birds to be monitored. The data obtained will be compared with PIT-tag data to provide a comprehensive picture of goshawk population dynamics.
Population structure in Addax nasomaculatus
	This project aimed to assess the possible sub-species status of Addax nasomaculatus populations in captivity. Using historical and contemporary samples, we sequenced the mitochondrial control region to compare differences in wild addax from different regions
Genetic variability in Rocky Mountain Big Horn Sheep
	Big horn sheep have been extensively researched to examine levels of genetic diversity at both microsatellite loci and the MHC complex, in order to inform conservation management. This project focussed on a previously unstudied population of big horn sheep, measuring diversity within the group and comparing the results with data from other western USA populations.
Adaptive variation in the red walnut, Juglans regia
	The red walnut, native to central and western Asia, displays variation in a number of morphological and physiological traits throughout its range. This study utilised provenance trials and measures of population genetic structure to investigate potential adaptive traits in this locally important tree species.
Species verification in hamadryas baboons at Paignton Zoo, U.K.
	This project aimed to investigate the presence of non-hamadryas baboon DNA within the existing hamadryas population, caused by possible historic hybridisation. Using a combination of species-specific genetic markers and detailed pedigree information, it was possible to assess the likelihood of past hybridisation events.
Sex determination in two-toed sloths
	Captive breeding programmes rely on knowing the sex of individuals that are being paired together, however this is not always straightforward. Morphological sex-determination is extremely difficult in many species including the two-toed sloth. In order to avoid invasive veterinary procedures, we were able to assist the zoo by undertaking a series of genetic sex tests based on DNA extracted from hair samples. Tests were corroborated by sequencing sections of the mammalian SRY gene amplified from male sloths.
Paternity analysis in Grevy’s zebra
	The objective of this study forMarwell Zoo was to assess the ability to assign paternity in Grevy’s zebra populations using DNA recovered from blood, hair and faecal samples. DNA profiles were generated for each sample type using a set of thirteen microsatellites. The technique was then successfully used to identify individual zebras involved in the European Endangered Species Breeding Programme.
Genetic population assessment of red squirrels in North Wales
	Red squirrels have been declining across Wales over the past fifty years. A project to conserve one of the last remaining populations is running on the island of Anglesey. We were contracted to examine levels of genetic diversity within the population and examine the genetic structure of Welsh red squirrels within the U.K. Results indicate much reduced genetic diversity relative to populations in northern England.

DNA recovery & species identification of historical textile whale baleen
	The extensive use of whale-baleen in historical clothing manufacture has resulted in the preservation of whale products in textile conservation projects. Working with the Textile Conservation Centre, we have been able to recover DNA from baleen removed from an 18th century corset. Sequence data identified it as belonging to a historical right-whale population. Further funding is currently being sought to extend this research. Publication (Eastop & McEwing 2004.pdf)
Identification of otter populations from spraint analysis
	The return of otters to the rivers of North Wales has been recorded from observations of footprints and otter spraint, but there is very little information about where they have returned from and in what number. This study using DNA recovered from fresh spraint has shed light on the source populations moving back into the region and approximate numbers that are now present.
