Stable dingo population structure and purity over 11 years of lethal management

Interactions between predators and humans are a key driver of human-wildlife conflicts and can underpin the management of predator populations. Management of the impacts of dingoes (Canis familiaris) on livestock and native species is a prime example of a persistent and contentious predator management issue with potential impacts on the integrity of dingo populations. To manage the potential impacts of dingoes and their control, it is imperative to understand the effects of control approaches on their populations in the short and long term. Hybridisation of dingoes with domestic dogs (C. familiaris) threatens the genetic integrity of pure dingoes. It has been hypothesised that lethal control of dingoes can facilitate hybridisation by disrupting pack social structures leading to increased dingo-domestic dog interactions. Here we use dingo genetic samples from three distinct sampling periods: 2009, 2014, and 2020, within the Murchison Regional Vermin Cell (MRVC) area in Western Australia ...捕食者与人类的互动是引发人兽冲突的核心驱动因素，同时也是捕食者种群管理的重要基础。澳洲野犬（Canis familiaris）对家畜与本土物种造成的影响的防控工作，是一类长期存在且颇具争议的捕食者管理议题，其潜在影响直接关乎澳洲野犬种群的遗传完整性。为管控澳洲野犬的潜在影响并推进其种群防控工作，我们亟需明晰各类防控手段对其种群的短期与长期效应。澳洲野犬与家犬（C. familiaris）的杂交行为，正危及纯种澳洲野犬的遗传完整性。有假说提出，对澳洲野犬实施致死性防控会破坏其种群的社群结构，进而增加澳洲野犬与家犬的互动频次，最终促进杂交行为的发生。 本研究采集了澳大利亚西部默奇森区域害兽防控区（Murchison Regional Vermin Cell, MRVC）内三个不同采样时段（2009年、2014年与2020年）的澳洲野犬遗传样本……
