Does the Tundra Bean Goose (Anser serrirostris) Follow the Green Wave Throughout its Entire Spring Migration

Following the flush of spring growth of primary production (the “green wave” hypothesis) has been applied as a universal explanation for spring migration timing of avian herbivores. However, studies of the green wave hypothesis have focused on species feeding intensively on above-ground primary p...

Seasonal and regional differences in migration patterns and conservation status of Swan Geese (Anser cygnoides) in the East Asian Flyway

The Swan Goose (Anser cygnoides) breeds across Mongolia and adjacent China and Russia and winters exclusively in China. It is globally threatened, showing long-term major range contractions and declining abundance, linked to habitat loss and degradation. We remain ignorant about the biogeographic...

Contrasting habitat use and conservation status of Chinese-wintering and other Eurasian Greater White-fronted Goose (Anser albifrons) populations

GPS/GSM tracking data were used to contrast use of (i) habitats and (ii) protected areas between three Arctic-nesting Greater White-fronted Geese (Anser albifrons, GWFG) populations throughout the annual cycle. We wished to demonstrate that the East Asian Continental Population (wh...

[In Polish] The process of becoming independent in the post-fledling period of the telemetry tracked White-tailed Eagles Haliaeetus albicilla from the Bory Tucholskie National Park

In 2019–2020, as part of the research on the spatial ecology of the White-tailed Eagle in the “Bory Tucholskie” National Park (PNBT), 4 GPS loggers were given to large chicks. In 2019, chicks from two different nests were equipped with these devices, and in 2020, another two chicks from the same...

R package for animal behavior classification from accelerometer data—rabc

Increasingly, animal behavior studies are enhanced through the use of accelerometry. To allow translation of raw accelerometer data to animal behaviors requires the development of classifiers. Here, we present the “rabc” (r for animal behavior classification) package to assist researchers with th...

[In Chinese]Application of a technology coupling satellite remote sensing and the internet of things for dynamic land and bio-resource management

自然保护区是包含了土地自然资源、野生和畜牧生物以及人类社会的复杂系统,本研究以牲畜和草地资源关系为模式场景,通过哨兵2号(Sentinel-2)卫星影像提取的归一化植被指数(normalized difference vegetation index,NDVI)分析生物质覆盖率,通过穿戴式智能终端获得牦牛的位置和行为信息,并利用最小凸多边形法(minimum convex polygon, MCP)和整体动态加速度(overall dynamic body acceleration, ODBA)计算得到牲畜行为信息和活动量状态。

An evaluation of machine learning classifiers for next-generation, continuous-ethogram smart trackers

Background Our understanding of movement patterns and behaviours of wildlife has advanced greatly through the use of improved tracking technologies, including application of accelerometry (ACC) across a wide range of taxa. However, most ACC studies either use intermittent sampling that hinders...

Rees, Lei Cao, Anthony D. Fox

Two of the most fundamental ecological questions about any species relate to where they occur and in what abundance. Here, we combine GPS telemetry data, survey data and expert knowledge for the first time to define two distinct flyways (the East Asian Continental and West Pacific flyways), migra...

The migratory Mute Swan Cygnus olor population in East Asia

Until recently, almost nothing was known about the migration routes, flyway structure and population status of the Mute Swan Cygnus olor in East Asia. Here, we use a combination of GPS telemetry data, collar resightings, published literature and expert advice to update existing knowledge of its s...

Rapid decline of the geographically restricted and globally threatened Eastern Palearctic Lesser White-fronted Goose Anser erythropus

The Lesser White-fronted Goose Anser erythropus, which breeds across northern Eurasia from Norway to Chukotka, is globally threatened and is currently classified as Vulnerable by the International Union for Conservation of Nature. The Eastern Palearctic population of the species was thought to breed
