A novel framework to modelling regulation of prey populations by a generalist predator

Abstract Background In ecological communities, a predator often feeds on several food sources. Such a predator is known as a generalist, and its feeding is traditionally modelled by a functional response. However, the conventional concept of the functional response is not applica...

Сharacteristics of aquatic invertebrates in the upper basin of Bakhta River (Krasnoyarsk Krai, Tungus Plateau) in the context of the distribution of relict and Baikal species

Pioneering studies were conducted on zooplankton, meiozoobenthos and macrozoobenthos assemblages in mountain-type taiga rivers: the Bakhta, Surindakan and Maigungda, as well as in the Yenisei River at the confluence with the Bakhta River. The studied watercourses are oligotrophic...

Thermally Induced lux-Operon Promoter of Photorhabdus hainanensis and Photorhabdus temperata

The bioluminescence of entomopathogenic bacteria of the genus Photorhabdus was considered to be constitutive. However, it has recently been shown that under heat shock conditions, lux-operon is activated in Photorhabdus temperata cells. In the present study, bioluminescence therm...

Vegetation-driven shifts in soil microbial communities and predicted carbon-cycling potential across soil depths in High-Arctic islands

Abstract Background Arctic ecosystems are experiencing unprecedented warming, driving vegetation expansion into previously barren areas. Although Arctic greening is expected to alter biogeochemical cycles, how vegetation cover shapes soil microbial communities and their functiona...
