Abstract As a cause of ecosystem disturbances, phytophagous insects are known to directly influence the element and organic matter (OM) cycling in ecosystems by their defoliation and excretion activity. This study focuses on the interplay between sho

Publikováno v: Microorganisms, Vol 8, Iss 11, p 1694 (2020)

Microbial communities play a key role for central biogeochemical cycles in the subsurface. Little is known about whether short-term seasonal drought and rewetting events influence the dominant microbes involved in C- and N-cycles. Here, we applied me

Conversion of tropical forests is among the primary causes of global environmental change. The loss of their important environmental services has prompted calls to integrate ecosystem services (ES) in addition to socio-economic objectives in decision

Yellow meadow ant (Lasius flavus) mound building activity alters the physico-chemical properties of grassland soils. In this study, L. flavus mediated changes were assessed along vegetation and soil type differences within four plots located on two s

Drought and rewetting events enhance nitrate leaching and seepage-mediated translocation of microbes from beech forest soils

Autor: Alexander Tischer, Karin Potthast, Beate Michalzik, Martina Herrmann, Markus Krüger, Florian F. K. Deckner, Kirsten Küsel

Nitrification in forest soils is often associated with increased leaching of nitrate to deeper soil layers with potential impacts on groundwater resources, further enhanced under scenarios of anthropogenic atmospheric nitrogen deposition and predicte
