The behaviour of sika and red deer during the rutting season is highly variable in relation to vocalization, habitat preference during the rut, and onset and termination of rutting. The red deer is a native species in Central Europe, but the areas where it lives in sympatry with the introduced sika deer have been increasing in the last three decades. Such situation can be found in the Doupovské hory Mts., where sika deer has been intensively spreading. Hybridization between the two species and changes in behaviour are the most important problems. In this study we prove the shift in the rutting period shown by both species. To evaluate the shift in the rutting season, we used a very extensive long-term data set on deer shot within the Military Training Area. These changes occur very slowly, however, and are very difficult to monitor and evaluate in the wild. Based on our results, the timing of the rutting season has converged at the mean rate of 0.62 day per year (rutting season starts later in the red deer and earlier in the sika deer).

Lesion Morphology

Sections of tuberculous lesions from 23 elk ( Cervus elaphus nelsoni) and red deer ( Cervus elaphus elaphus), 12 fallow deer ( Dama dama), 10 sika deer ( Cervus nippon), and 30 cattle were examined and compared. Lesions were scored for caseous necrosis, mineralization, neutrophils, macrophages, giant cells, and acid-fast bacilli. Some differences in lesion morphology between the species were noted. Elk/red deer lesions had marked variation and often differed from bovine lesions in several characteristics; elk/red deer lesions usually had scattered peripheral mineralization rather than central mineralization and contained more neutrophils and fewer giant cells than did bovine lesions. Fallow deer lesions contained more giant cells but were otherwise indistinguishable from elk lesions. Sika deer lesions had more giant cells and fewer neutrophils than did lesions from cattle or other cervid species. Sika deer giant cells were larger and contained more nuclei than did giant cells in the other species.

AbstractThe Endangered Corsican red deer Cervus elaphus corsicanus was extirpated from Corsica in the early 1970s, at which time the Sardinian population fell to <250 individuals. The Sardinian authorities agreed to protect this subspecies and to secure its reintroduction in Corsica, a natural choice, considering ethological and historical descriptions. Since the beginning of 1985, when the first deer destined for captive breeding and eventual reintroduction arrived in Corsica, the population increased from 13 Sardinian founders to 106 captive animals under constant monitoring in three enclosures (Quenza, Casabianda and Ania di Fium'Orbu). The sites of Quenza, Chisà and Santo Pietro di Venaco were selected by the Regional Nature Park of Corsica for the reintroduction into the wild that began in 1998. Currently the size of the whole Corsican population is c. 250 individuals. These deer are still closely monitored and studied, both in enclosures and in the wild, to secure the long-term conservation of this subspecies. The Corsican and Sardinian populations together now total slightly >1,000, and the subspecies could therefore be downgraded to Near Threatened on the IUCN Red List.

AbstractHybridization is a natural process at species range boundaries, but increasing numbers of species are hybridizing due to direct or indirect human activities. In such cases of anthropogenic hybridization, subsequent introgression can threaten the survival of native species. To date many such systems have been studied with too few genetic markers to assess the level of threat resulting from advanced backcrossing. Here we use 44,999 single nucleotide polymorphisms and the ADMIXTURE program to study two areas of Scotland where a panel of 22 diagnostic microsatellites previously identified introgression between native red deer (Cervus elaphus) and introduced Japanese sika (Cervus nippon). In Kintyre we reclassify 26% of deer from the pure species categories to the hybrid category whereas in the NW Highlands we only reclassify 2%. As expected, the reclassified individuals are mostly advanced backcrosses. We also investigate the ability of marker panels selected on different posterior allele frequency criteria to find hybrids assigned by the full marker set, and show that in our data, ancestry informative markers (i.e. those that are highly differentiated between the species, but not fixed) are better than diagnostic markers (those markers that are fixed between the species) because they are more evenly distributed in the genome. Diagnostic loci are concentrated on the X chromosome to the detriment of autosomal coverage.

The present paper focuses on three species belonging to the family Hippoboscidae: Hippobosca equina, Lipoptena cervi and L. fortisetosa – haematophagus ectoparasites typical of cervids. In Europe, the forest flies (H. equina) are observed mainly in horses and cattle, but the primary host of this parasite is the red deer (Cervus elaphus). The host group of deer keds Lipoptena sp. include different ruminant species belonging to Cervidae (moose, red deer, sika deer, fallow deer, roe deer and maral) and Bovidae family (mouflon, european bison, cattle, sheep and goat). Furthermore, some species of carnivores (European badger, dog and red fox) can be accidental hosts. The presence of adult hippoboscid flies in the environment shows strong seasonality. One or two generations of H. equina occurs from May to October. The alate forms of univoltine Lipoptena cervi and probably multivoltine L. fortisetosa appear from August to September, and from June to September, respectively. During warm autumns, both species can be observed in late October, or even November. Hippobosca equina and Lipoptena cervi are native species, unlike the foreign L. fortisetosa. This Asian species was noted in Europe for the first time in the 1960s, and has rapidly spread in numerous countries. The most probable way of L. fortisetosa introduction to Europe was translocation via host (probably sika deer), or natural dispersion throughout Eurasia. Therefore L. fortisetosa should be treated as an alien invasive species in Poland and Europe. Interest in these three neglected dipteran species has increased after reports of their veterinary and medical importance. All these parasite species are able to attack humans. Bites of these insects are considered painful, cause skin lesions with the presence of characteristic persistent pruritic papules, and, in extreme cases, may result in an anaphylactic reaction. Hippoboscids can play a role in the transmission of bacterial pathogens, including Anaplasma and Bartonella genera, dangerous for humans and animals. Permanent and intensive attacks on humans, during the seasonal mass occurrence of these parasites, can hinder forestry work, as well as harvesting, recreation, and hunting activities in forested areas.

The aim of the present study was to assess the in vivo competence of in vitro-produced sika deer (Cervus nippon nippon) embryos after freezing–thawing and transfer into red deer (Cervus elaphus hippelaphus) recipients. During the breeding season, 11 adult sika deer hinds were synchronized as oocyte donors with an intravaginal sponge (45 mg of fluorogestone acetate, FGA) inserted for 12 days and removed immediately after laparoscopic ovum pick-up (LOPU), and renewed after 3 days. Ovarian stimulation was induced with an i.m. injection of 75 µg of cloprostenol (Estrumate) given on Day 8, followed by 3 i.m. injections of 0.1, 0.1, and 0.05 IU of ovine FSH (Ovagen) on Days 10 and 11 at 12-h intervals. On Day 12, hinds were anesthetized and oocytes were collected by LOPU from follicles >2 mm using an 18 G needle under moderate vacuum. COC were recovered and morphologically evaluated for quality (graded from 1 to 5). COC were then submitted to in vitro maturation, fertilization, and culture (IVM, IVF, and IVC) as described previously (Locatelli Y et al. 2005 Theriogenology 64, 1729–1739). For IVC, embryos were co-cultured with a monolayer of ovine oviduct epithelial cells in synthetic oviduct fluid medium supplemented with 10% FCS. On Day 8 post-insemination, all sika deer embryos at the blastocyst stage were cryopreserved via a standard bovine slow-freezing protocol. Of 44 LOPU sessions performed during the 1-month study, an average of 7.5 � 0.38 follicles were aspirated (mean � SEM), allowing the recovery of 3.65 � 0.38 COC per hind and per session, of which 80.0% were suitable for IVM (grades 1 and 2). Of 142 oocytes recovered, 57 cleaved after IVF (40.1%), and 14 embryos (24.6% of cleaved) reached the blastocyst stage after 8 days. At the end of the breeding season, 7 adult red deer hinds were synchronized as embryo recipients by inserting 2 intravaginal sponges per female (90 mg of FGA), for 13 days. Injections (i.m.) of 400 IU of eCG and 125 µg of cloprostenol (Estrumate) were administered 72 h before sponge removal. At Day 8 after sponge removal, straws containing frozen embryos were thawed and cryoprotectant was removed as described previously (see Locatelli Y et al. 2005 Theriogenology 64, 1729–1739). Two sika deer embryos were surgically transferred into uterine horn (unilaterally) of each red deer recipient. One of 7 red deer recipients was diagnosed pregnant by ultrasonography on Day 56. A healthy male sika deer fawn was born unassisted after 224 days of gestation. No complications were observed in initial recognition of the sika deer fawn by the red deer surrogate mother, nor in subsequent interactions. To our knowledge, this is the first report of an interspecific pregnancy obtained after in vitro embryo production and embryo transfer in deer species. In conclusion, interspecific embryo transfer after IVP may represent a useful tool for the preservation and amplification of captive residual populations of endangered deer species. Further studies are required to increase the rate of cleavage after LOPU-IVF as well as viability of frozen–thawed IVP embryos.
