野生动物学报, 2014 近年来,红外触发相机凭借各种优势,在野生动物种类与数量调查中得到越来越多的应用。2012年6月～2013年3月,在安西极旱荒漠国家级自然保护区山区的水源及兽径处放置20部红外触发相机,以检验该技术在山区动物种类调查中的应用效果。监测期间共获得独立照片732张,经辨认,共拍摄到25种野生动物,隶属2纲,10目,15科,25属。哺乳类拍摄率最高的3种是北山羊(Capra ibex)、岩羊(Pseudois nayaur)及中亚兔(Lepus capensis); 鸟类拍摄率最高的3种为红嘴山鸦 ...

野生动物学报中华穿山甲（Manis pentadactyla）夜行穴居，体表覆盖鳞片，个体外观特征差异较小，基于红外相机影像拍摄到的体貌特征进行个体识别较难，因此探讨一种基于红外相机影像与比例尺估测体长进行中华穿山甲个体识别的方法。在笼舍内布设不同高度的红外相机并拍摄中华穿山甲影像，利用ImageJ软件计算中华穿山甲在红外相机影像中的体长测量值，并计算在不同高度条件下红外相机拍摄的中华穿山甲体长误差值。结果表明：红外相机最佳的布设高度为0.8 m，相对误差为2.76%。基于上述结果 ...

Survey optimization for invasive Burmese pythons informed by camera traps 基于自动相机监测技术的入侵物种缅甸蟒的调查优化
Wildlife Letters, Volume 1, Issue 3, Page 143-148, September 2023., 2023 We evaluated the utility of camera traps to survey invasive Burmese pythons in the Florida Keys by deploying cameras pointed towards target areas of known radiotagged snakes under two trigger mechanisms—motion‐triggered or timelapse. We estimated detection probability and diel activity to optimize future surveys using timelapse camera traps and paired ...

Methods in Ecology and Evolution, Volume 14, Issue 7, Page 1732-1746, July 2023., 2023 Abstract Our knowledge on the responses of permafrost ecosystems to climate warming is critical for assessing the direction and magnitude of permafrost carbon‐climate feedback. However, most of the previous experiments have only been able to warm the air and surface soil, with limited effects on the permafrost temperature.

Evaluating the impact of caribou habitat restoration on predator and prey movement
Conservation Biology, Volume 37, Issue 2, April 2023., 2023 Abstract Fragmentation of the boreal forest by linear features, including seismic lines, has destabilized predator–prey dynamics, resulting in the decline of woodland caribou (Rangifer tarandus caribou) populations. Restoration of human‐altered habitat has therefore been identified as a critical management tool for achieving self‐sustaining woodland ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Early diagnosis of liver cancer demands high sensitivity, high specificity, convenience and real‐time monitoring capabilities. However, it encounters challenges such as low concentration of markers, numerous interfering factors, and limitations of detection technologies.

野生动物学报, 2021 神农架素以“白化动物之乡”闻名中外。2019年5月29日和6月13日，于神农架国家公园官门山管护中心辖区内用同一红外相机先后2次拍摄到白化小麂。根据所获得的野生个体影像资料信息确定为成年雄性白化小麂个体，这为神农架白化动物的广泛存在增添了新证据，也为神农架白化动物的分布、行为与动态监测等调查研究奠定了基础。

Integrative Conservation, Volume 5, Issue 1, Page 125-136, March 2026.We collated detections of the sun bear from new and previously published camera trap studies across its range. We then analysed these detections at two different spatial scales to assess the habitat associations and diel activity of this species. We found that the sun bear is tolerant to moderate habitat disturbances. ABSTRACT Degraded tropical forests,
