agricultural landscapes; butterflies; chalk grasslands; community structure; diet; fauna; flight; functional diversity; grassland management; habitats; intensive farming; land use; meadows; orchards; overwintering; territoriality; voltinism; wildlife; Germany
Abstract:
... Alteration of agricultural land use has led to a widespread loss of biodiversity in human-dominated landscapes. Degradation and gradual disappearance of natural and semi-natural habitats has become a global conservation problem. Together, intensive agriculture and the abandonment of extensively farmed areas endanger the wildlife of European landscapes. Our study aims to explore the complex process ...

We studied 67 kettle holes (KH) in an agricultural landscape in northeastern Germany using landscape‐scale metatranscriptomics to understand the responses of active bacterial, archaeal and eukaryotic communities to land‐use type. These KH are proxies of the millions of small ...

Abstract:
... In the Earth's Critical Zone, water plays an essential role as a collector and transporter of metabolites and their transformation products. It is generally believed that the chemical profiles of groundwater are strongly impacted by land use. However, predictors for the effects of above-ground natural and anthropogenic activities on below-ground chemistry are rare. We reasoned that comparing groun ...

Abstract:
... Plant and soil microbial diversities are linked through a range of interactions, including the exchange of carbon and nutrients but also herbivory and pathogenic effects. Over time, associations between plant communities and their soil microbiota may strengthen and become more specific, resulting in stronger associations between plant and soil microbial diversity. We tested this hypothesis at the ...

Local agri-environmental schemes, including hedgerows, flowering strips, organic management, and a landscape rich in semi-natural habitat patches, are assumed to enhance the presence of beneficial arthropods and their contribution to biological control in fruit crops. We studied the influence of local factors (orchard management and adjacent habitats) and of landscape composition on the abundance ...

Abstract:
... A shift has been predicted in future nitrogen emission scenarios from nitrous oxide to higher proportions of ammonium compounds. To investigate the interaction between increasing nitrogen load and varying nitrate:ammonium ratios (NO₃⁻:NH₄⁺), we performed a mesocosm experiment in an oligotrophic lake in southern Germany. We fertilized mesocosms with both roughly natural and four times the natural n ...

Abstract:
... The loss of weed biodiversity in agricultural fields is a global issue that needs to be counteracted to preserve their supported ecosystem services and food webs. Many short-term efforts are undertaken to conserve weed species, especially already endangered ones, but several years after expiration, eventually result in species-poor communities. Understanding drivers of community composition is key ...

Abstract:
... After completion of an exploration well, sandstones of the Exter Formation were hydraulically tested to determine the hydraulic properties and to evaluate chemical and microbial processes caused by drilling and water production. The aim was to determine the suitability of the formation as a reservoir for aquifer thermal energy storage. The tests revealed a hydraulic conductivity of 1–2 E-5 m/s of ...

Abstract:
... QUESTIONS: The understorey vegetation of temperate forests may serve as an indicator of long‐term change in site conditions. We investigated vegetation change of the herb and moss layers during the last 50 yr in managed European beech (Fagus sylvatica) and sessile oak (Quercus petraea) forests under chronic N deposition. We tested the hypotheses that (1) the species richness of the understorey veg ...

Abstract:
... Organic farming and agroforestry are considered as sustainable alternative agricultural practices for intensive agriculture. In a long-term field trial in Scheyern Germany, we evaluated the effects of 21-year organic farming and 4-year agroforestry (robinia and poplar) on microbial community and microbial residues. Microbial biomass and microbial community were determined by fumigation–extraction ...

Abstract:
... Benthic microbial communities (BMCs) play important roles in the carbon cycle of lakes, and benthic littoral zones in particular have been previously highlighted as biogeochemical hotspots. Dissolved organic matter (DOM) presents the major carbon pool in lakes, and although the effect of DOM composition on the pelagic microbial community composition is widely accepted, little is known about its ef ...

Abstract:
... A number of modelling results suggested thermocline shifts as a consequence of global climate change in stratifying lakes. Abundance and composition of the phytoplankton assemblage is strongly affected by the stratification patterns, and therefore, change in the thermocline position might have a substantial effect on this community or even on the whole lake ecosystem. In this study, thermocline de ...

However, microbial community structure and function can be affected by environmental conditions, such as regional climate and soil properties and, moreover, by human activity through forest management. We examined the biomass and composition of microbial assembl ...

Knowledge-driven management for wastewater treatment plant (WWTP) performance becomes increasingly important considering the globally growing production of wastewater and the rising demand of clean water supply. Even though the potential of microbial organisms (bacteria and protists) as bioindicators for WWTP performance is well known, it is far from being fully exploited for routine monitoring pr ...

Many studies that have addressed this issue suffer from a lack of geographic extent. Here, we investigate the fungal community structure of 117 Fagus sylvatica logs in relation to wood physico-chemical properties and secreted ligninolytic enzymes, a ...
