Novel ecosystems are increasingly common worldwide, particularly in areas heavily impacted by humans such as urban and peri-urban landscapes. Consequently, interest in their potential contribution to biodiversity conservation is growing, including their ability to sustain populations of threatened species. However, few studies have explored whether novel habitats can support viable populations over time and how they compare to less modified, remnant habitats.

We investigated the capacity for novel habitats to support an endangered mammal, the southern brown bandicoot (Isoodon obesulus obesulus: Peramelidae), in a highly-modified landscape near Australia's second largest city, Melbourne. We compared bandicoot abundance and body condition between five novel and two remnant sites, and examined whether novel sites support residency and key demographic processes necessary for bandicoot population persistence. We found that bandicoot abundance was higher at novel than remnant sites, with the highest abundance at the novel site with the most urbanised surroundings. Female body condition was similar between novel and remnant sites. The majority of bandicoots at novel sites were resident, and breeding activity, recruitment of first-year adults, and survival of mature adults were observed at all novel sites.

Our results demonstrate the potential significance of novel habitats for conserving threatened species within heavily-modified landscapes, and encourage us not to judge the quality of habitats on their novelty alone. Broadening our appreciation of the potential value of novel ecosystems could increase off-reserve species conservation opportunities, a key priority within the context of the Anthropocene and unprecedented global change and biodiversity loss.

新型生态系统在世界范围内越来越普遍，尤其是在受到人类严重影响的地区，例如城市和城市周边景观。因此，人们越来越关注它们对生物多样性保护的潜在贡献，包括它们维持受威胁物种种群的能力。但是，很少有研究探索新颖的栖息地是否能够随着时间的推移支持生存的种群，以及它们如何与修饰程度较低的残余栖息地进行比较。

我们调查了新型栖息地的能力，以支持濒临灭绝的哺乳动物，南部棕带猴（Isoodon obesulus obesulus：Peramelidae），在澳大利亚第二大城市墨尔本附近经过高度修改的景观中。我们比较了五个新奇遗址和两个残余遗址之间的土匪丰富度和身体状况，并检查了新遗址是否支持土匪种群持续存在所必需的居住和主要人口统计过程。我们发现，新居中的带子足动物的丰度高于遗迹，在城市化程度最高的小说中，高足动物的丰度最高。新旧网站之间的女性身体状况相似。在新发现的地方，大多数土匪都居于其中，在所有新发现的地方都观察到了繁殖活动，第一年成年的募集和成年成活。

我们的结果表明，新颖的栖息地对于在经过大量修改的景观中保护濒危物种具有潜在的意义，并鼓励我们不要仅凭其新颖性就判断栖息地的质量。扩大我们对新型生态系统潜在价值的认识可能会增加保护区外物种的保护机会，这是人类世以及前所未有的全球变化和生物多样性丧失的背景下的一项关键优先事项。
