Subject:
Capricornis; Cervus nippon; DNA; defecation; discriminant analysis; feces; pellets; species identification; surveys; ungulates; Japan
Abstract:
... The fecal pellets and fecal pellet group characters of two ungulates, the Japanese serow and sika deer, were compared in Tokushima, Japan, where the species occur sympatrically. Species identification based on 82 fecal DNA samples revealed that 28 and 54 fecal pellet groups were from Japanese serow and sika deer, respectively. The mean values of three fecal pellet groups characters, the maximum di ...

Although vitrification is widely used for tissue cryopreservation, it is challenging to obtain viable cells in facilities that lack adequate experimental tools, such as zoos. In this study, we established a simple tissue cryopreservation method for obtaining viable cells. Using mouse tissues of the ears and ...

Abstract:
... Fences are the most effective defenses against crop damage by deer. If properly constructed and maintained, fences mitigate crop damage. However, it is difficult to enclose farmland completely when a fence crosses a river. This study evaluated the effectiveness of olfactory (wolf urine), visual (flashlight), and sound deterrents against deer at the intersection of river and fence. These deterrents ...

Invasive mammals have irreversibly altered ecosystems of Hawai‘i and other tropical Pacific islands in numerous cases through novel herbivory, predation, and diseases, thereby causing the disproportionate extinction of flora and fauna that occur nowhere else on Earth. The control and eradication of invasive mammals is the single most expensive management activity necessary for restoring ecological ...

Indo-Pacific bottlenose dolphins (Tursiops aduncus) off Amakusa-Shimoshima, approximately 200 individuals, form relatively large groups frequently exceeding 100 individuals and show high site fidelity to the area around Tsuji Island, northern coast of Amakusa-Shimoshima. This suggests that individual dolphins may have long interaction times with many other individuals. Consequently, competition be ...
