Do Père David's Deer Lose Memories of Their Ancestral Predators?
Whether prey retains antipredator behavior after a long period of predator relaxation is an important question in predator-prey evolution. Père David's deer have been raised in enclosures for more than 1200 years and this isolation provides an opportunity to study whether Père David's deer still respond to the cues of their ancestral predators or to novel predators. We played back the sounds of...
متن کاملA new gene mapping resource: interspecies hybrids between Père David's deer (Elaphurus davidianus) and red deer (Cervus elaphus).
Three male F1 hybrids between Père David's deer and red deer were mated to red deer to produce 143 backcross calves. The pedigrees are a rare example of a fertile hybrid between evolutionarily divergent species. We examined the use of these families for genetic mapping of evolutionarily conserved (Type I) loci by testing for genetic linkage between five species-specific protein variants and 12 ...
متن کاملSex-Age Related Rumination Behavior of Père David’s Deer under Constraints of Feeding Habitat and Rainfall
Extensive studies have been conducted on the rumination behavior of domestic herbivores. However, studies on wild animals are limited, particularly wild animals with specific ruminating parameters. In this study, Père David's deer, a previously extirpated species, was observed to analyze the effects of sex-age, feeding habitat, and rainfall on rumination behavior in the Dafeng Nature Reserve, C...
متن کاملPenile fibrosarcoma tumor in a bull
This is a report of a penile fibrosarcoma in a two-year-old crossbred Holstein bull. The ulcerated tumormass with dimensions of 7 × 9 × 6.5 cm, was enveloped the glans and body of the penis. It had a white-graycolor at cross section appearance. There was no metastatic evidence of regional lymph node enlargement.Histopathologically, elongated spindle-shaped cells arranged densely in the interwov...
متن کاملImperial trophy or island relict? A new extinction paradigm for Père David's deer: a Chinese conservation icon
Determining the 'dynamic biogeography' of range collapse in threatened species is essential for effective conservation, but reconstruction of spatio-temporal patterns of population vulnerability and resilience can require use of non-standard ecological data such as historical archives. Père David's deer or milu, one of the few living mammal species that has become extinct in the wild, is histor...
