Abstract

The extinction of the Mexican wolf (Canis lupus baileyi) has been linked to human hunting, a decline in prey populations, and habitat loss. This study assessed the abundance and biomass of potential prey of the Mexican wolf for its reintroduction in northeastern Sonora, Mexico. Using capture-recapture models and camera traps across different mountain ranges. The findings confirmed a high availability of potential prey biomass in Natural protected areas such as the APFF-Bavispe and Sierra San Luis. Twenty-three mammal and nine bird species were identified as potential prey for the Mexican wolf during 6,875 trap days. Other predators recorded in the region include black bear, puma, and jaguar. The highest relative abundance index observed for white-tailed deer (3.20 records/100 trap days). The prey biomass in the study area is 33 kg/km², mainly white-tailed deer and collared peccary. This biomass can support a population of 20 to 40 Mexican wolves; however, social factors must also be considered for the reintroduction of these wolves. There is a strong biological basis for the reintroduction of the Mexican wolf in northeastern Sonora, and it is crucial to initiate actions that promote effective wildlife management alongside livestock activity.

墨西哥西北部重新引入墨西哥狼（Canis lupus baileyi）的潜在地点：猎物和生物量

墨西哥狼（Canis lupus baileyi）的灭绝与人类狩猎、猎物数量减少和栖息地丧失有关。本研究评估了墨西哥索诺拉东北部重新引入墨西哥狼的潜在猎物的丰度和生物量。利用捕捉-再捕捉模型和跨越不同山脉的相机陷阱。研究结果证实，在APFF-Bavispe和Sierra San Luis等自然保护区，潜在猎物生物量的可用性很高。在6875天的陷阱中，23种哺乳动物和9种鸟类被确定为墨西哥狼的潜在猎物。在该地区记录的其他食肉动物包括黑熊、美洲狮和美洲虎。白尾鹿的相对丰度指数最高，为3.20条/100陷阱日。研究区猎物生物量为33 kg/km2，主要为白尾鹿和有领pecary。这些生物量可以养活20到40只墨西哥狼；然而，重新引入这些狼也必须考虑社会因素。在索诺拉东北部重新引入墨西哥狼有很强的生物学基础，在牲畜活动的同时，采取行动促进有效的野生动物管理是至关重要的。

期刊介绍： The Journal for Nature Conservation addresses concepts, methods and techniques for nature conservation. This international and interdisciplinary journal encourages collaboration between scientists and practitioners, including the integration of biodiversity issues with social and economic concepts. Therefore, conceptual, technical and methodological papers, as well as reviews, research papers, and short communications are welcomed from a wide range of disciplines, including theoretical ecology, landscape ecology, restoration ecology, ecological modelling, and others, provided that there is a clear connection and immediate relevance to nature conservation. Manuscripts without any immediate conservation context, such as inventories, distribution modelling, genetic studies, animal behaviour, plant physiology, will not be considered for this journal; though such data may be useful for conservationists and managers in the future, this is outside of the current scope of the journal.
