Context: Outside its breeding season, the marsupial carnivore the spotted-tailed quoll (Dasyurus maculatus) is apparently largely unaffected by aerial baiting for dingoes and other wild dogs (Canis familiaris). However, the potential impact of aerial baiting during spring on female spotted-tailed quolls carrying and weaning young remains unquantified.

Aim: The survivorship of female quolls and their pouch young was investigated after aerial baiting at two sites representing the northern and southern part of their New South Wales range. The null hypothesis was that aerial baiting would not lead to direct mortality of any adult females or higher pouch young mortality over that reported in the published literature under normal conditions.

Methods: In total, nine female quolls with pouch young and eight male quolls were trapped, fitted with GPS/VHF collars containing mortality sensors and released at their point of capture. After trapping ceased, meat baits nominally containing 6 mg of 1080 and 50 mg of the biomarker rhodamine B were deployed by helicopter at both sites at the maximal permissible rate of 40 baits km⁻¹. We monitored collared quolls daily for 4–5 weeks for mortality then retrapped animals and sampled whiskers for evidence of the biomarker. The fate of pouch young was also followed throughout our study by examining pouches of adult females and camera trapping at maternal den sites.

Key Results: No collared quolls died. After the daily monitoring period, 10 quolls, including all six collared female quolls, were trapped at the southern site, and whisker samples taken and assayed for Rhodamine B. Seven (4 females and 3 males) tested positive for rhodamine B, indicating consumption of baits. Separate bands of the biomarker in whisker samples indicated that most animals that tested positive had been exposed to multiple baits. At the northern site, four quolls (including two females and two males) tested positive for rhodamine B from the nine sampled. Post-baiting inspection of pouches of all trapped adult female animals, together with camera trapping at den sites, showed that the development of pouch young was unaffected by the baiting. Camera trapping arrays set across both sites continued to record the animals that were exposed to baits well beyond the baiting events, including evidence of breeding in a subsequent season.

Conclusion: Our aerial baiting programs had no observable impact on the collared female quolls, or their ability to raise and wean young. These findings are consistent with results from all previous field-based experimental studies, which show no population-level impacts of 1080 baits on spotted-tailed quolls.

Implications: Land managers should not be concerned about impacts of aerial baiting for wild dogs on spotted-tailed quolls, either in autumn or in spring during the breeding season.

背景：在繁殖季节以外，有袋食肉动物斑尾类的拟南芥（Dasyurus maculatus）显然不受空中诱饵和野狗（Canis熟悉）的影响。然而，春季诱饵对携带和断奶幼仔的斑尾雌雄的潜在影响仍未得到量化。

目的：在代表新南威尔士山脉北部和南部的两个地点进行空中诱饵后，对雌性雄性及其幼小袋的成活率进行了调查。零假设是，在正常条件下，空中诱饵不会导致任何成年雌性的直接死亡，也不会导致袋装幼仔的死亡率更高。

方法：总共捕获了9只雌性带小袋鼠的雄性比目鱼和8只雄性比尔的雄性比尔，装配了装有死亡率传感器的GPS / VHF项圈，并在捕获点放行。诱捕停止后，直升飞机在两个地点部署了标称含有6 mg 1080和50 mg生物标志物若丹明B的肉毒饵，最大允许速率为40毒饵km ^-1。我们每天监测领类动物的死亡率，为期4-5周，然后重新捕获动物并取样胡须以寻找生物标记物的证据。在我们的整个研究过程中，还通过检查成年雌性小袋和在母体巢穴诱捕照相机来追踪年轻小袋的命运。

主要结果： 没有衣领的死灵死亡。每日监测期结束后，在南部站点捕获了10只鹌鹑，包括所有6头衣领雌性鹌鹑，采集了晶须样品并进行了若丹明B的分析。其中有7名（4名雌性和3名雄性）的罗丹明B呈阳性，表明食用了诱饵。晶须样品中生物标志物的单独条带表明，大多数测试结果呈阳性的动物已暴露于多种诱饵。在北部现场，从九个采样点中，四个鹌鹑（包括两个雌性和两个雄性）的罗丹明B测试呈阳性。诱饵对所有被诱捕的成年雌性动物的小袋进行诱饵后检查，再加上照相机在巢穴的诱捕，显示诱饵不会影响幼小囊的发育。

结论：我们的空中诱饵程序对领领雌性猛或它们的抚育和断乳能力没有明显影响。这些发现与以前所有基于实地的实验研究的结果一致，后者显示1080饵对斑点尾quo类动物没有种群水平的影响。

启示：在繁殖季节的秋季或春季，土地管理人员不应该担心用空中诱饵wild狗对斑尾鹌鹑的影响。
