野生动物学报, 2004 中国幅员辽阔,从西北到东南跨寒、温、热等不同气候带。从生境类型上分,有多种森林、各类湿地、草原和沙漠等。复杂多变的生境孕育了十分丰富的鸟类资源。其中有一个比较特别的类群,即号鸟形目鸟类,俗称“猫头鹰”,它们是一类夜行性猛禽。

野生动物学报, 1995 １９８５—１９８６年对连环湖狩猎场水禽资源进行了调查，共发现常见水鸟７３种，其中雁形目鸟类和形目鸟类数量较大，为狩猎鸟类的重要组成部分、运用系统分类和分层抽样的方法，对四个狩猎经营区内的狩猎鸟类（类、鸭雁类、白骨顶）进行了统计，狩猎鸟类总数（Ｎ）及其变化区间为Ｎ＝Ｓ［Ｘ±ｔ０．３（１７）×ｓｚ］＝３４２００±９９６Ｏ只，相对误差Ｅ＝２９％，精度Ｐｃ＝１—Ｅ＝７１％。同时，通过观察和猎物比较，研究了资源的动态变化，发现现阶段鸭类中鹊鸭和红头潜鸭占绝对优势，凤头潜鸭，翘鼻麻鸭、鸿雁、白骨顶数量下降较为明显 ...

Wildlife Letters, Volume 1, Issue 2, Page 71-78, June 2023., 2023 Oaks are often removed as part of longleaf pine restoration; however, it is unclear if oak patches produce important resources for native wildlife. We studied wildlife use of the transition between longleaf pine woodlands and hardwood hammocks. We found these areas support a variety of wildlife species and future management and restoration of longleaf ...

Modeling total predation to avoid perverse outcomes from cat control in a data‐poor island ecosystem
Conservation Biology, Volume 36, Issue 5, October 2022., 2022 Abstract Data‐hungry, complex ecosystem models are often used to predict the consequences of threatened species management, including perverse outcomes. Unfortunately, this approach is impractical in the many systems that have insufficient data to parameterize ecosystem interactions or reliably calibrate or validate such models.

Unravelling the processes between phenotypic plasticity and population dynamics in migratory birds
Journal of Animal Ecology, Volume 91, Issue 5, Page 983-995, May 2022., 2022 This work highlights the critical role of the stopover stage of northward migration in the influence of migration tactics and population dynamics of migratory birds across the whole annual cycle. The authors also demonstrate the key processes linking individual migration tactics and population dynamics.

Ecological Applications, Volume 31, Issue 6, September 2021., 2021 Abstract Species loss has attracted much attention among scientists for more than half a century. However, we have little information on the trends in phylogenetic and functional changes behind the species loss although this information is always asynchronous and important for conservation and management. We measured community trends in Anatidae (ducks

Using Wikipedia to measure public interest in biodiversity and conservation
Conservation Biology, Volume 35, Issue 2, Page 412-423, April 2021., 2021 Abstract The recent growth of online big data offers opportunities for rapid and inexpensive measurement of public interest. Conservation culturomics is an emerging research area that uses online data to study human–nature relationships for conservation. Methods for conservation culturomics, though promising, are still being developed and refined.

Trends and knowledge gaps in field research investigating effects of anthropogenic noise
Conservation Biology, Volume 35, Issue 1, Page 115-129, February 2021., 2021 Abstract Anthropogenic noise is a globally widespread sensory pollutant, recognized as having potentially adverse effects on function, demography, and physiology in wild animals. Human population growth and associated changes in urbanization, transportation, and resource extraction all contribute to anthropogenic noise and are predicted to increase in ...

Effects of spatial autocorrelation and sampling design on estimates of protected area effectiveness
Conservation Biology, Volume 34, Issue 6, Page 1452-1462, December 2020., 2020 Abstract Estimating the effectiveness of protected areas (PAs) in reducing deforestation is useful to support decisions on whether to invest in better management of areas already protected or to create new ones. Statistical matching is commonly used to assess this effectiveness, but spatial autocorrelation and regional differences in protection ...

Subspecies taxonomy reflects social and geographic patterns of taxonomic effort in tetrapods
Conservation Biology, EarlyView.Abstract Subspecies have been used in conservation biology to account for intraspecific patterns in genetic diversity, which is crucial to long‐term population viability. Although over 3200 subspecies are currently assessed by the International Union for Conservation of Nature Red List, their biological relevance remains controversial.
