... The Arctic is under great pressure due to climate change. Drones are increasingly used as a tool in ecology and may be especially valuable in rapidly changing and remote landscapes, as can be found in the Arctic. For effective applications of drones, decisions of both ecological and technical character are needed. Here, we provide our method planning workflow for generating ground-cover maps with ...

Abstract:
... The lower Yangtze River region in China was a centre of early Neolithic rice cultivation and animal domestication. It is also an important habitat for wintering birds; however, our current understanding of prehistoric avifaunal resource utilisation by human populations in this region is limited. To clarify the use of birds by early Neolithic rice-cultivating societies further, we analysed bird rem ...
... A 6-year-old female goose (Branta hutchinsii) from a group of ornamental exotic geese was found dead due to severe respiratory failure, followed by emission of haemorrhagic sputum and blood clots from the beak and nostrils, and then collapse. At necropsy, the cause of death was attributed to a total of 76 helminth parasites found in the trachea and lungs, then identified as Cyathostoma bronchialis ...
Anser; breeding; case studies; geese; integrated pest management; models; monitoring; population size; water birds; Norway
Abstract:
... Development of integrated population models (IPMs) assume the absence of systematic bias in monitoring programs, yet many potential sources of systematic bias in monitoring data exist (e.g., under-counts of abundance). By integrating multiple sources of data, we can assess whether various sources of monitoring data provide consistent inferences about changes in population size and, thus, whether m ...

Abstract:
... The decline in emergent reed beds in eutrophic shallow lakes in Europe has been linked to multiple factors, such as adverse water and sediment quality, shoreline development and fixed water level preventing recolonisation, recreational disturbances and herbivory by geese and muskrat. This study analyses the relative importance of these factors in a historical context and tests experimentally what ...
... Global agriculture faces a daunting challenge of feeding the increasing world population using the finite environmental resources. An efficient pathway is to integrate the agricultural and pastoral systems in rural regions. This study investigated the hypothesis of raising geese in cornfields (RGICF), which is an ecological engineering approach based on the principle of agro-pastoral integration, ...

... Understanding how animals select for habitat and foraging resources therein is a crucial component of basic and applied ecology. The selection process is typically influenced by a variety of environmental conditions including the spatial and temporal variation in the quantity and quality of food resources, predation or disturbance risks, and inter‐ and intraspecific competition. Indeed, some of th ...
Anser; adults; breeding; breeds; case studies; foraging; geese; habitats; migratory behavior; nesting; nesting sites; nests; predation; predators; summer; Arctic region
Abstract:
... As colonies fill up with more individuals, areas of preferred nesting habitat can become scarce. Individuals attracted to the colony by the presence of conspecifics may then occupy nest sites with different habitat characteristics to that of established breeders and, as a result, experience lower nesting success. We studied a rapidly growing colony of Svalbard pink-footed geese Anser brachyrhynchu ...
... In December 2008, bird species in two geographically distant holdings were found positive for H5 viruses following the annual Avian influenza serological screening in Belgium. The virological tests performed identified in one holding a low‐pathogenic avian influenza (LPAI) virus subtype H5N2, and a H5 LPAI virus was identified by real‐time PCR and direct sequencing at the second holding. The first ...

... Lake Het Groene Eiland was created in the beginning of 2008 by construction of dikes for isolating it from the surrounding 220-ha water body. This so-called claustrum of 5 ha was treated using lanthanum-modified clay (Phoslock®) to control eutrophication and mitigate cyanobacterial nuisance. Cyanobacteria chlorophyll-a were significantly lower in the claustrum than those in the reference water bod ...
algorithms; case studies; chemistry; economic performance; engineering; flight; geese; humans
Abstract:
... Inspired by the biologic nature of flying geese, process goose queue (PGQ) approaches toward plantwide process optimization are explicitly introduced in this paper along with applications in real-time optimization (RTO). Taking advantage of ad-hoc PGQ metrics, process variables associated with a process unit could be accordingly identical with geese positions of a PGQ. Motivated by the self-organi ...

Abstract:
... A high proportion of threatened and near-threatened species in the world now inhabit farmland. Although much data regarding the impact of agriculture on farmland biodiversity have been accumulated in Western countries, such information, particularly on the impact of rice cultivation, is fragmentary in other parts of the world and has rarely been disseminated internationally. Therefore, this paper ...
... We review interactions between waterfowl and wetlands and outline the shifts that are likely to occur within these relationships through global climate change. We highlight the relative paucity of research on populations of tropical waterfowl and their food plants, and use an iconic tropical species of waterfowl, the Magpie Goose (Anseranas semipalmata), as a case study. We provide background on t ...
