Published: Jan. 21, 2025

The Japanese marten (Martes melampus) inhabits forest environments in Japan, ranging from extensive natural forests to fragmented landscapes agricultural areas. Anecdotally, there have been some observations of using urban green spaces. Evidence corroborate this, however, is lacking. Here, we report on the presence martens a small woodland patch surrounded by residential neighbourhoods Uji City, Kyoto central Japan. In 2023, obtained four independent camera-trapped images and one video species this patch. We also found samples its faeces. While it uncertain whether was resident or temporary visitor patch, these records confirm that can extend range into spaces Our adds limited systems highlights importance understanding their distribution habitat use face expansion.

To understand and sustain carnivore communities ecosystems, it is important to determine the mechanisms of coexistence potential competitive interactions among carnivores. This study examined how carnivores coexist climatic environmental shifts affect medium-sized The seasonal trophic niche overlap red foxes, Japanese martens, raccoon dogs in cool-temperate zone Japan was evaluated, where there are distinct changes, especially from heavy snowfall. Faecal analysis foxes (n = 107), martens 125), 100) 2019 2021 showed that share main food items their annual dietary relatively high despite co-occurrence These results have indicated potentially strong interactions, various competition avoidance besides partitioning may facilitate Japan. also found degree varied by season, indicating conditions, particularly abundance snowfall, guilds.

Evaluation of multiple behavioral responses of sika deer to human hunting pressures

Journal of Wildlife Management, Journal Year: 2023, Volume and Issue: 88(1)

Published: Sept. 19, 2023

Abstract Several ungulate populations have become overabundant worldwide, resulting in ecological and social effects. Wildlife managers must establish effective population control programs to mitigate these negative influences. Hunting is a significant mortality factor for ungulates, which exhibit sensitive behavioral responses toward hunting activities. need comprehensive understanding of the different pressures across seasons. We developed conceptual method evaluate multiple human applied this sika deer ( Cervus nippon ) Hokkaido, Japan, during August November 2015. measured flight behavior, spatial avoidance, temporal activity shift non‐hunting seasons 4 regions with pressures. Although we did not observe clear difference initiation distance among study areas or seasons, showed avoidance season high pressure. Furthermore, were more active at night higher pressures, regardless season. Collectively, results suggest that responded pressure by changing diel nocturnal throughout year avoiding risky (i.e., around roads) season, rather than increasing when they encounter humans. Our can be used efficient program wildlife managers, as it considers spatiotemporal variations flexible behaviors response

Seasonal changes in forest road use by mammals in a heavy snowfall area, north-eastern Japan: effects of management intensities

Journal of Vertebrate Biology, Journal Year: 2024, Volume and Issue: 73(24001)

Published: April 22, 2024

Forest road use by mammals can vary in response to both the management intensity of forest roads and seasonal changes their environments. We investigated effects heavy snowfall areas on environments with different intensities. The field survey was conducted north-eastern Japan from August 2022 July 2023. Using camera traps, we observed frequency occurrence each species roads, decommissioned interior sites. employed a generalized linear mixed model analyse relationship between events site types seasons. Red foxes occurred significantly more frequently than interiors during all Raccoon dogs selectively used spring winter. However, Japanese martens, hares, wild boar only occasionally roads. These findings suggest that selectivity varies among species, for seasonally.

Anthropogenic linear features exhibit greater mammal activity relative to surrounding game trails in a woody savannah

African Journal of Ecology, Journal Year: 2024, Volume and Issue: 62(3)

Published: July 3, 2024

Abstract Anthropogenic development throughout African savannahs results in changes to landscapes and wildlife habitat. Linear features (e.g. roads powerlines) have become more prevalent can reshape how many mammal species navigate the landscape. This study assesses mammals use anthropogenic linear game trails a woody savannah via camera traps. We found that greater number of species, especially carnivores, used rather than trails. Additionally, 15 taxa were associated with features, whereas only four trails, suggesting may alter landscape use.

Comparison of the conservation of medium and large-sized mammals in a national park and military area

Research Square (Research Square), Journal Year: 2023, Volume and Issue: unknown

Abstract National parks (NP) and military areas (MA) preserve natural ecosystems. Although both regions have positive negative effects on animal communities, studies comparing their impacts conservation are limited. We monitored mammalian communities using 21 sensor cameras in a MA (6 sites) NP (15 located Gyeryongsan Mountain, South Korea from May to November 2021 compare the of medium large-sized mammals between two regions. Forty-one environmental variables, including anthropogenic geographical factors, were extracted different spatial ranges (50, 500, 1000 m). A linear model non-metric multidimensional scaling used identify factors influencing community diversity. also analyzed species habitat type preferences multispecies occupancy compared temporal activities Species diversity was similar sites, with most animals preferring habitats lower slopes at greater distances human trails. Only Korean hare ( Lepus coreanus ) preferred eight found. Active periods for regions, except differences some carnivore species. not all affected by activity, over NP. The carnivores especially able flexibly alter active locations response activities, where activity more prevalent. Thus, strategies should be implemented improve success, such as accessible inaccessible section separation.

林道脇の水たまりにおけるトウホクサンショウウオの繁殖利用の実態：山形県庄内地方における事例

Ecology and Civil Engineering, Journal Year: 2023, Volume and Issue: 26(2), P. n/a - n/a

Published: Jan. 1, 2023

本研究では,環境省レッドリストで準絶滅危惧に選定されているトウホクサンショウウオ(Hynobius lichenatus)を対象に,林道脇の水たまりが繁殖場所としてどのように利用されているのか,卵嚢および幼生の調査によって明らかにした.山形県庄内地方において 2022 年 4 月から 6 月に林道脇の水たまりを探索し,対象種の卵嚢調査をおこなった.ここで得られた卵嚢対数と各環境要因(水温,pH,リターの有無,水面から地面までの高さ,森林までの距離,道路の舗装の有無,水たまりの種類,水たまりの面積,水深,アカハライモリの個体数,半径 100 m 以内の樹冠被覆率)の関係を,ゼロ過剰な負の二項分布を仮定した一般化線形混合モデル(ZINB モデル)によって解析した.さらに,卵嚢が確認された水たまりにおいて,幼生の変態前である 8 9 月に対象の個体数を調査し,産卵した場所で幼生が生存しているかどうか確認した.林道脇の水たまりを 250 地点調査した結果,85 地点で対象の卵嚢が確認されたことから,林道脇に生じる水たまりが産卵場所として利用されていることがわかった. ZINB モデルの結果から,リターがあり,水深が深く,アカハライモリが少なく,森林まで近く,道路の舗装がないという水たまりにおいて卵嚢対数が多くなる傾向がみられた.卵嚢が確認された地点のうち 75 地点で幼生を調べた結果,20 地点では幼生が確認されたものの, 55 地点では幼生は確認されなかった.このことから,産卵場所として利用された地点の多くで,幼生が死亡または流失したと考えられた.
