Overabundance of sika deer and immunocontraception
The impact of deer overabundance is a worldwide problem. Along with habitat expansion and population increase, damage by sika deer to the forest ecosystem and agriculture has become a serious issue in Japan. Deer also transmit a number of diseases and parasites to humans and livestock. The overabundance of deer is a result of their strong fecundity, and therefore the present situation should, i...
متن کاملEhrlichia chaffeensis Infection of Sika Deer, Japan
To determine whether Ehrlichia chaffeensis exists in Japan, we used PCR to examine blood from sika deer in Nara, Japan. Of 117 deer, 36 (31%) were infected with E. chaffeensis. The E. chaffeensis 16S rRNA base and GroEL amino acid sequences from Japan were most closely related to those of E. chaffeensis Arkansas.
متن کاملIdentification and morphological characteristics of dental neonatal line in sika deer (Cervus nippon).
The dental neonatal line of the sika deer (Cervus nippon) was identified experimentally using chronological labeling methods. In the enamel, prominent dark lines were observed under transmitted light, and the number of increments between the dark line and labeling line was almost consistent with the day-age at the time of labeling injection. Therefore, we identified the dark line as the enamel ...
متن کاملCytogenetic variation in farmed stock of Dybowski's sika deer.
The chromosome constitution of Dybowski's sika deer was studied on the basis of 15 samples obtained from farmed stock maintained in an enclosure. The diploid chromosome number was 2n=68, 2n=67 and 2n=66. The constitutive heterochromatin (C-bands) was located in the centromeric regions of all acrocentric chromosomes. Metacentric chromosomes were C-negative. Chromosomes of three pairs proved to b...
متن کاملCo-phylogeography and morphological evolution of sika deer lice (Damalinia sika) with their hosts (Cervus nippon).
Lice are obligate parasites of mammals and birds and have become an important model for studies of host-parasite co-evolution and co-phylogenetics. Population genetic and phylogeographic studies represent an important bridge between microevolution and co-phylogenetic patterns. We examine co-phylogeographic patterns in sika deer and their parasitic lice. Co-phylogeographic patterns in deer and l...
