- Abstract:
- ... Changes in land use and agricultural intensification threaten biodiversity and ecosystem functioning of small water bodies. 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:
- ... Soil microbial community structure is determined by environmental conditions and influenced by other factors, such as the intensity of the land use management. Studies addressing the effect of environmental factors and management on grassland soil microbial communities at the continental scale are missing, and the wide range of ecosystem services provided by these ecosystems are thus also wanting. ...

- Abstract:
- ... Biogeochemical models of vegetation dynamics could potentially be used to complement empirical studies on the effect of plant species richness. A key precondition is the simulation of species coexistence. While community scale models regularly incorporate respective processes, models at the field or landscape scale used for larger scale assessments, require additional model development. However, i ...

- Abstract:
- ... Sustainable forest management increasingly favors mixtures, but effects on many ecosystem characteristics, such as biocontrol by predators and their biodiversity, are still not well understood. This knowledge gap can be particularly problematic when these mixtures include non-native tree species, such as Douglas fir (Pseudotsuga menziesii (Mirb.) Franco), which are planted because of their high gr ...

- Abstract:
- ... Soil biodiversity is threatened by intensification of land use. The consequences of different land use on belowground biodiversity remain insufficiently explored for soil protists. Alongside being abundant and extremely diverse in soil, protists provide many ecosystem services: key players in the microbial loop, turnover of organic matter and stimulation of plant growth-promoting rhizobacteria.

Trait‐based approaches are promising but yet rarely applied to understand community dynamics in response to changing environmental conditions. Here, we investigate seasonal succession patterns of functional traits in phytoplankton communities and how nutrient reductions (o ...

Multiple invaders commonly co‐occur in native ecosystems and in some cases have been shown to facilitate each other thus exacerbating impacts on native species, while in other cases one invader may reduce the impact of another due to competition. We therefore aimed at identifying mechanisms driving alien species interactions. We conducted a common garden experiment investigating all pairwise combi ...

- Abstract:
- ... The profound intensification of agricultural practices by increased application of agro-chemicals, short crop rotations and ploughing resulted in loss of soil fertility, erosion and accumulation of soil-borne plant pathogens. Soil microbial communities are key players in ecosystem processes and are intimately linked to crop productivity and health. Thus a better understanding of how farming practi ...

- Abstract:
- ... The combination of increasing atmospheric depositions of reactive nitrogen (N) and the highly effective diminishing of external phosphorus (P) loadings can change key nutrient ratios in lake ecosystems. Consequently, ratios of dissolved inorganic N (DIN) to dissolved P (DP) in lakes are increasing. However, potential consequences for aquatic organisms are as yet far from understood. We formulated ...

- ... Human management of ecosystems can have direct or indirect effects on species communities. How species communities are affected by management is a key question in ecology and nature conservation. As keystone taxon, changes in ant communities can have sustained consequences for entire ecosystems. In forests, management has been shown to have an overall negative effect on ant communities in tropical ...

In this study, thermocline de ...

- Abstract:
- ... QUESTIONS: Does site alteration caused by mining impede spontaneous colonization of native species assemblies to the advantage of neophytic species at the landscape unit and plant community scale? To what extent can mined site conditions support the establishment of rare plant species assemblies that are locally novel but of regional conservation value? What effects have dispersal limitation and s ...

- Abstract:
- ... Exotic plant invasions are thought to alter productivity and species richness, yet these patterns are typically correlative. Few studies have experimentally invaded sites and asked how addition of novel species influences ecosystem function and community structure and examined the role of competitors and/or consumers in mediating these patterns. We invaded disturbed and undisturbed subplots in and ...

- Abstract:
- ... Research on soil microbiota is one of the frontiers in biodiversity research. Bacterivores, such as protozoans, contribute significantly to mineralization processes and key ecosystem functions in soil. Protozoan grazing on rhizobacteria stimulates microbial mineralization processes and thereby indirectly nutrient cycling. Understanding the diversity of protozoans and their fundamental functions is ...

Human‐induced changes in anthropogenic landscapes are a predominant threat to biodiversity and have been documented to affect mutualistic interactions between plants and animals, such as avian seed dispersal. Interactions between fleshy‐fruited plants and frugivorous birds are highly seasonal in temperate ecosystems. Nevertheless, combined effects of landscape modification and seasonal variation o ...

In managed forests, the abundance and diversity of saproxylic insect species and beetles in particular has been argued to be primarily limited by the amount of dead wood while the importance of other factors for community composition of this functional group has been largely neglected. It has also been argued that management regimes that lead to increasing amounts of dead wood in forests will incr ...

During recent years, increasing incidences of summer droughts – likely driven by climate change – reduced the dilution potential of low-order streams for secondary treated wastewater also in temperate Europe. Despite the potential risks to ecosystem integrity, there is a paucity of knowledge regarding the effects of different wastewater dilution potentials on ecosystem functions. The present study ...

- Abstract:

The work described here employs a new combination of methods to identify parasite species and study parasite succession in fry of perch (Perca fluviatilis) from Lake Constance, Germany. Classical morphological diagnostics are combine ...

- Abstract:

We thus investigated whether ecological and life-history traits differ between butterfly communities of grasslands with different land-use intensity. We conducted butterfly transect surveys in 137 grassland sites in three reg ...

Local conservation activities caused changes ...

In temperate regions, biological soil crusts (BSCs: complex communities of cyanobacteria, eukaryotic algae, bryophytes, and lichens) are not well investigated regarding community structure and diversity. Furthermore, studies on succession are rare. For that reason, the community assembly of crusts representing two successional stages (initial, 5 years old; and stable, >20 years old) were analyzed ...

However, their quantitative significance and possible role in the latter systems is still little studied, in particular in coastal regions. Therefore, we investigated the abundance and composition of Gram positive bacteria in the Wadden Sea, a tidal fla ...
