Nico Eisenhauer (born 22 February 1980, in Lindenfels, Germany) is a German biologist, soil ecologist and professor for experimental interaction ecology at Leipzig University.
Nico Eisenhauer obtained his diploma in animal ecology at the Darmstadt University of Technology in 2005, and then was awarded a doctorate in 2008 from Darmstadt University of Technology with a thesis "Earthworms in a plant diversity gradient: Direct and indirect effects on plant competition and establishment." From 2008 to 2010 he worked as Postdoc in the Jena Experiment at the Darmstadt University of Technology and Georg August University Göttingen, from 2010 to 2012 a Postdoc at the University of Minnesota and then at the Technical University of Munich where he was an Emmy Noether group leader. He then habilitated at the Georg August University Göttingen in Ecology and Zoology.
From 2012–2014, he worked as associate professor for Terrestrial Ecology at the Friedrich Schiller University Jena. Since 2014, he has been a full professor for Experimental Interaction Ecology [1] at the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig and Leipzig University. Since 2015 he is Speaker of the Research Unit “Jena Experiment,” [2] funded by the German Research Foundation. He is also Head of the iDiv Ecotron [3] and the MyDiv experiment, [4] as well as founding member of the "Soil BON" consortium. [5] His main research focus is on reasons for and ecosystem consequences of changes in biodiversity. [6]
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area.
The University of Jena, officially the Friedrich Schiller University Jena, is a public research university located in Jena, Thuringia, Germany.
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations. The current rate of extinction is sometimes considered a mass extinction, with current species extinction rates on the order of 100 to 1000 times as high as in the past.
Soil ecology is the study of the interactions among soil organisms, and between biotic and abiotic aspects of the soil environment. It is particularly concerned with the cycling of nutrients, formation and stabilization of the pore structure, the spread and vitality of pathogens, and the biodiversity of this rich biological community.

The microbial loop describes a trophic pathway where, in aquatic systems, dissolved organic carbon (DOC) is returned to higher trophic levels via its incorporation into bacterial biomass, and then coupled with the classic food chain formed by phytoplankton-zooplankton-nekton. In soil systems, the microbial loop refers to soil carbon. The term microbial loop was coined by Farooq Azam, Tom Fenchel et al. in 1983 to include the role played by bacteria in the carbon and nutrient cycles of the marine environment.
Functional diversity, composition, and species richness affect the biogeochemical processes of ecosystems. However, the degree to which these factors influence ecosystems and whether that influence is significant is debated.
The work of the Helmholtz Centre for Environmental Research – UFZ covers both basic research and applied research.
In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume per unit of time, such as grams per square metre per day. The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity.
Invasive species of earthworms from the suborder Lumbricina have been expanding their range in North America. Earthworms are considered one of the most abundant macroinvertebrates in the soil of ecosystems in temperate and tropical climates. There are around 3,000 species known worldwide. They are considered keystone species in their native habitats of Asia and Europe because, as detritivores, they alter many different variables of their ecosystem. Their introduction to North America has had marked effects on the nutrient cycles and soil profiles in temperate forests. These earthworms increase the cycling and leaching of nutrients by breaking up decaying organic matter and spreading it into the soil. This thins out the soil rapidly because earthworms do not require a mate to reproduce, allowing them to spread fast. Since plants native to these northern forests are evolutionarily adapted to the presence of thick layers of decaying organic matter, the introduction of worms can lead to a loss of biodiversity as young plants face less nutrient-rich conditions. Some species of trees and other plants may be incapable of surviving such changes in available nutrients. This change in the plant diversity in turn affects other organisms and often leads to increased invasions of other exotic species as well as overall forest decline. They are considered one of the most invasive animals in the Midwestern United States along with feral swine.
The German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig is a DFG research center with staff and members at its main locations in Halle, Jena and Leipzig. It is a central facility of Leipzig University, and is run together with the Martin Luther University Halle-Wittenberg and Friedrich Schiller University Jena, as well as in cooperation with the Helmholtz Centre for Environmental Research - UFZ. In addition, seven non-university research institutions belong to the iDiv consortium. iDiv was founded in 2012 and is funded by the DFG.
