Article Abstract

Despite being common amongst carnivore mammals, behavioral interference between wild herbivore species is poorly documented. Particularly, in temperate areas, where the ungulate guild is composed of a few species, and large-sized rodents are scarce, most cases of interspecific interactions involve at least one alien species. In this work, we report the first data on behavioral interactions between roe deer, , and crested porcupine, . Aggressions by crested porcupines toward roe deer were observed in 34 out of 202 observations of both species feeding at the same site. In the other 168 observations, roe deer and porcupines shared the same feeding area, without any interaction. In 58% cases of interaction, porcupines chased and pushed roe deer away from feeding areas, and in several other cases, roe deer were bitten, or injured with quills. Aggressions by porcupines occurred mostly during warm months, when roe deer are mostly solitary and when competition for food between these species is suggested to be the highest, and against single female individuals.

Little is known about the vomeronasal organ (VNO), which is associated with social behaviors through pheromone detection in mammals, particularly ungulates. We investigated the distribution of phospholipase C beta 2 (PLCβ2), a marker of solitary chemosensory cells (SCCs), in the VNO of the Korean roe deer (Capreolus pygargus). PLCβ2-positive cells were detected in both the sensory and non-sensory epithelium of the VNO, and resembled the bipolar cells.

The aim was to evaluate the effectiveness of semen cryopreservation and oocyte vitrification in roe deer as a potential method of gamete preservation for endangered deer species. Sperm were isolated from the cauda epididymis of fourteen bucks ( = 14). The motility measure (CASA) and morphology of fresh semen (FS) and frozen-thawed semen (TS) were compared.

Hard ticks (Ixodidae family) are primary vectors of zoonotic diseases, including severe fever with thrombocytopenia syndrome (SFTSV), anaplasmosis, babesiosis, Lyme borreliosis, and ehrlichiosis. The roe deer (), a key host for tick-borne diseases, is widely distributed on Jeju Island, Republic of Korea (ROK). Although the increased interactions between deer, livestock, and humans have raised concerns about zoonotic disease transmission, this area has remained understudied.

Hepatitis E is an emerging zoonosis caused by the hepatitis E virus (HEV) and is recognised worldwide. Wild boars are considered one of the main reservoirs of the zoonotic HEV-3 genotype. However, HEV-3 has also been detected in many other wildlife species.
