1. Nitrogen Uptake from Different Sources by Non-GMO Soybean Varieties

Author:
Rymuza, Katarzyna; Radzka, Elżbieta; Wysokiński, Andrzej

Agronomy 2020 v.10 no.9

Subject:
Anser; Rhizobium; crop residues; cultivars; environmental factors; field experimentation; genetically modified organisms; growing season; isotope dilution technique; microorganisms; nitrogen; non-genetically modified foods; roots; seeds; soil; soybeans; stable isotopes; symbiosis; weather; Central European region; Poland
Abstract:
... Soybean has the ability to live in symbiosis with microorganisms and take up nitrogen from the atmosphere, fertiliser and soil reserves. The amount of nitrogen taken up from these sources depends on many biotic and abiotic factors, e.g., the rhizobium species, cultivar, as well as weather and agricultural conditions. A field experiment was conducted in eastern Poland (central Europe) in two succes ...

Abstract:
... Climate change and human activities influence species biodiversity by altering their habitats. This paper quantitatively analyzed the effects of climate change on a migratory bird. The Lesser White-fronted Goose (LWfG), a species which migrates via the middle and lower reaches of the Yangtze River region, is an herbivorous species of high ecological value. It is an endangered species threatened by ...

Abstract:
... Here we review the state-of-the-art of pathogens in select marine and terrestrial key species of the Baltic Sea, i.e. ringed seal (Pusa hispida), harbour seal (Phoca vitulina), grey seal (Halichoerus grypus), harbour porpoise (Phocoena phocoena), common eider (Somateria mollissima), pink-footed goose (Anser brachyrhynchus) and white-tailed eagle (Haliaeetus albicilla). This review is the first to ...

Journal of avian biology 2020 v.51 no.3

Subject:
Anser; energy conservation; environmental factors; flight; geese; leadership; migratory behavior; migratory birds; parents; social class; spring; wind
Abstract:
... Many migratory animals travel in large social groups. Large, avian migrants that fly in V‐formations were proposed do so for energy saving by the use of up‐wash by following individuals and regularly change leadership. As groups have been rather homogeneous in previous work, we aimed to explore leadership and its flight mechanics consequences in an extremely heterogeneous case of social migration, ...

5. Using integrated population models for insights into monitoring programs: An application using pink-footed geese

Subject:
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 ...
