Additionally, body condition was estimated by external veterinary examinations. We assessed the relationships between cat age and the occurrences of traffic accidents. The ages of cats ranged from 0- to 9-years-old, more than 70% of which were yearlings. However, 2- to 4 year-old cats were not found among the dead; thus, the age distribution of the accident victims was biased toward yearling and older individuals. Traffic-related mortality among male yearlings occurred frequently from autumn to winter (September-January) and did not overlap with the time of year when>1-year-old individuals frequently suffer from traffic accidents, except in September. Traffic-related mortality among yearling females occurred most frequently in November. Yearlings, which are generally born in spring and become independent of their mothers in autumn and winter, lack experience of artificial dangers such as cars. Furthermore, yearlings must make long trips to cross paved roads until they settle in their own home ranges. Thus, yearlings tend to frequently suffer from traffic-related accidents. The deaths of subadults without clinical problems and of resident cats in traffic accidents are likely to have negatively affected the population levels of this endangered species."},{"@language":"ja","@value":"1997年から2008年に交通事故に遭遇したツシマヤマネコ42個体(オス21個体、メス21個体)について、歯の萌出・交換状態と体サイズ及びセメント質年輪を用いて年齢査定を行い、交通事故と年齢の関係について分析した。また、栄養状態についても検討を試みた。交通事故遭遇個体の年齢は0歳から9歳であった。全体の70%以上が0歳で、2〜4歳の個体は確認されず、残り30%近くは5〜9歳の個体であった。交通事故の遭遇時期は、5〜9歳のオスでは2〜6月と9月であったのに対し、0歳のオスでは9月から1月に集中していた。0歳メスは11月に集中していた。0歳個体の事故が秋季から冬季に集中していたことから、春に生まれた仔が分散する時期に、新たな生息環境への習熟や経験が浅く、車への警戒が薄いため、事故に遭遇しやすいこと、また、分散の長距離移動の際に道路を横断する機会が増えることが要因と考えられた。栄養状態に問題のない亜成獣や定住個体が交通事故で死亡することは、個体群維持に負の影響を及ぼすと考えられた。"}],"abstractLicenseFlag":"allow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420001326231768704","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"40452966"},{"@type":"NRID","@value":"1000040452966"},{"@type":"NRID","@value":"9000346987448"},{"@type":"NRID","@value":"9000003185371"},{"@type":"NRID","@value":"9000243839030"},{"@type":"NRID","@value":"9000406290091"},{"@type":"NRID","@value":"9000346987439"},{"@type":"NRID","@value":"9000021952543"},{"@type":"NRID","@value":"9000403411179"},{"@type":"NRID","@value":"9000250176996"},{"@type":"NRID","@value":"9000346987422"},{"@type":"NRID","@value":"9000240041766"},{"@type":"NRID","@value":"9000415199158"},{"@type":"NRID","@value":"9000398383100"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0065905"}],"foaf:name":[{"@language":"ja","@value":"中西
