Management of ungulates is contested ground that lacks stakeholder agreement on desirable population sizes and management approaches. Unfortunately, we often miss information about extent of local impacts, for example on plant communities, to guide management decisions. Typical vegetation impact assessments like the woody browse index do not assess herbaceous plants, and differences in browse s...
This study provides a detailed description of the development of the gastrointestinal tract (GIT) of farmed red deer (Cervus elaphus) calves over the first 12 months of age. GIT development was measured using a combination of computerised tomography (CT) scanning and traditional slaughter plus dissection techniques. Red deer calves of a known birth date were randomly assigned to two treatment g...
A survey of naso-pharyngeal myiasis affecting red deer (Cervus elaphus) in southern Spain was conducted. The parasites involved were the larvae of Pharyngomyia picta and Cephenemyia auribarbis (Diptera:Oestridae), which coexist sympatrically within this host. Males and older animals had higher prevalences and intensities of fly larvae. Differences in behaviour and habitat use by male and female...
To elucidate the molecular mechanisms of red-green color vision in mammals, we have cloned and sequenced the red and green opsin cDNAs of cat (Felis catus), horse (Equus caballus), gray squirrel (Sciurus carolinensis), white-tailed deer (Odocoileus virginianus), and guinea pig (Cavia porcellus). These opsins were expressed in COS1 cells and reconstituted with 11-cis-retinal. The purified visual...
The forage-maturation hypothesis (FMH) states that herbivores migrate along a phenological gradient of plant development in order to maximize energy intake. Despite strong support for the FMH, the actual relationship between plant phenology and ungulate movement has remained enigmatic. We linked plant phenology (MODIS-normalized difference vegetation index [NDVI] data) and space use of 167 migr...
To evaluate the genetic diversity of the Xinjiang Tarim red deer (Cervus elaphus yarkandensis) population, we analyzed the frequencies of microsatellite alleles. Samples were collected from 3 isolated populations in Xaya, Lopnur and Qarqan of Xinjiang. Although 10 microsatellite loci were examined, alleles of 133 to 190 base-pairs were detected for only 3 loci: BM5004, BM4208 and BM888. The ave...
This study uses data from repeatedly measured forest monitoring plots (20 × 20 m) (n = 32) and nine ungulate exclosures (paired fenced and unfenced plots; 20 × 20 m) to show the effects of introduced ungulates on tree regeneration in Pureora Forest Park, central North Island, between 1974 and 2002. Results show that introduced ungulates, particularly red deer (Cervus elaphus scoticus), have sup...
This paper reviews the feeding requirements of adult red deer from nutritional, management and ecological perspectives. Particular emphasis is placed on the need to balance production objectives in the context of ecological sustainability. Topics such as feeding behaviour, feeding management, the relationship of body condition score to nutritional sufficiency, daily and seasonal feed intake req...
