Effects of temperature and body mass on soil communities by Birgit Lang( )

3 editions published between 2012 and 2013 in English and held by 29 WorldCat member libraries worldwide

The Earth is undergoing a climate change with predicted increases in temperature by up to 6° C until 2100. How this warming affects soil food webs is of fundamental interest for mankind as it may influence global food production. Due to the complexity of soil systems and species' interactions, simplifications are required in search for general patterns. One simplification used in this thesis is the categorization of species into con- sumer types such as carnivores, herbivores and detritivores, as physiological traits such as assimilation efficiencies and respiration rates are thought to dif
Compartmentalization and energy channels within the soil animal food web investigated by stable isotope (13C and 15N) and fatty acid analyses by Melanie Mira Maraun( )

Waldboden-Nahrungsnetze sind komplexe und heterogene Systeme. Trophische Beziehungen sind aufgrund der geringen Größe der Bodentiere und deren kryptischer Lebensweise, sowie des komplexen Gemisches basaler Ressourcen schwer ergründbar. Das Zersetzersystem wird trotz seiner fundamentalen Rolle in Zersetzungsprozessen und für das Funktionieren von

Extinctions in complex food webs: drivers and consequences by Amrei Binzer( )

2 editions published in 2013 in English and held by 27 WorldCat member libraries worldwide

Biodiversity is declining rapidly throughout the world. The rate of extinctions matches historical extinction waves and is likely to accelerate even further since two main drivers of biodiversity loss, global warming and nutrient enrichment, are predicted to increase in their impact over the coming decades. These extinctions are not only irreversible, diminishing the astounding diversity of life on our planet, but they also pose a direct threat to the health and wellbeing of humans. Thus, understanding the drivers and consequences of extinctions in existing species communities, and how they
Services and disservices driven by ant communities in tropical agroforests by Arno Christian Wielgoss( )

1 edition published in 2013 in English and held by 25 WorldCat member libraries worldwide

Agricultural productivity and human well-being are built upon ecosystem services and disservices. Ants in tropical agroecosystems drive a complex network of direct and indirect interactions between crops and their mutualists and antagonists. Until now most studies of ecosystem services of ants only focus on single interactions. But little is known about the dynamics between multiple interactions, their relative importance, how they are affected by ant community properties and how they add up to final yield quantity and quality. We tested the hypothesis that ecosystem services of ant communi
Soil animal food webs in temperate forests: effects of forest management on trophic structure as indicated by molecular gut content, stable isotope and fatty acid analyses by Olga Ferlian( )

2 editions published in 2014 in English and held by 18 WorldCat member libraries worldwide

The soil system comprises a high diversity of coexisting species interacting in close association. Generally, soil animals are assumed to be trophic generalists feeding on resources of even different trophic levels. The complex structure of soil habitats hampers locating specific resources and this results in feeding on a broad range of resources. It has been assumed that most decomposers rely on labile resources of high nutritional value, such as high quality litter and microorganisms. However, there is increasing evidence that recalcitrant carbon sources being physically and chemically st
The soil food web of temperate deciduous forests: litter and root resources as driving factors, and soil fauna effects on ecosystem processes by Diana Grubert( )

2 editions published in 2016 in English and held by 17 WorldCat member libraries worldwide

Above- and belowground communities have been investigated independently for long, but there is increasing evidence that both are intimately linked and depend on each other. Plants provide energy and nutrients for the belowground consumer community, both via litter and root exudates, thereby affecting soil biota. Simultaneous investigations of both litter and root exudate based pathways are scarce and therefore, the relative importance of roots as compared to litter as food resource for soil organisms remains unknown. Soil organisms, in turn, contribute to ecosystem processes like litter dec
Carbon flow in belowground food webs assessed by isotope tracers by Nicole Scheunemann( )

3 editions published between 2015 and 2016 in English and held by 17 WorldCat member libraries worldwide

Soil food webs are complex networks that consist of several trophic levels and taxonomic groups including soil microorganisms, protists, nematodes, annelids and soil arthropods. Interactions between and within trophic levels and taxonomic groups regulate important ecosystem functions such as the cycling of carbon (C) and nutrients, with soil microorganisms channeling resources from the base of the food web to higher trophic levels of meso- and macrofauna decomposers and predators. Root exudates and decomposing plant residues are the major basal resources of C, and recent research highlighte

Biodiversity response to land use change across scales by Murilo Dantas de Miranda( )

2 editions published in 2017 in English and held by 16 WorldCat member libraries worldwide

Landnutzungswandel hat negative Auswirkungen auf Biodiversitätsniveaus. In diesem Zusammenhang ist es wichtig zu verstehen, wie die verschiedenen Komponenten von Biodiversität und die Verteilungsmuster von Artenabundanz sich in Habitaten entlang eines ökologischen Suksessionsgradienten verändern. Um dies zu untersuchen wurden Nachtfalter an 84 genestet angeordneten Probestellen im Peneda-Gerês National Park in NW-Portugal mit Hilfe von Lichtfallen gefangen und bestimmt. Basierend auf diesen Daten zeigt diese Dissertation, dass im Modell Artenreichtum durch die Menge von Habitaten in Multi-Habitat-Landschaften besser vorhergesagt werden kann, als durch Patch-Größe oder Isolation. Diversitäts-Komponenten deuten ferner darauf hin, dass die Aufgabe landwirtschaftlicher Flächen wahrscheinlich die Vielfalt aller Arten, vor allem Waldarten, positiv beeinflusst. Darüber hinaus zeigen die Ergebnisse auch, dass Heterogenität von Lebensräumen wichtig ist, um die Vielfalt der Nachtfalter zu erhalten, insbesondere für Nicht-Wald-Arten. Zudem ändern sich, abhängig von Eigenschaften der Arten, die Muster der Verteilung der Abundanz einer Art entlang der betrachteten räumlichen Skala. Diese Arbeit gibt neue Einblicke in die Auswirkungen von Landnutzungswandel und besonders der Aufgabe von landwirtschaftlicher Nutzung von Flächen auf Biodiversität
Environmental heterogeneity-species richness relationships from a global perspective by Anke Stein( )

2 editions published in 2014 in English and held by 16 WorldCat member libraries worldwide

Spatial environmental heterogeneity (EH) is regarded as one of the most important drivers of species richness gradients worldwide. Its association with increased available niche space, provision of refuges, and opportunities for diversification through isolation and divergent adaptation are thought to promote species coexistence, persistence, and diversification. The exploration of potential positive effects of EH on species richness has intrigued ecologists and evolutionary biologists for decades. Consequently, a large body of literature exists on the relationship between EH and species ri

Land-use impacts on biodiversity and ecosystem functioning of complex multitrophic communities by Andrew D Barnes( )

2 editions published between 2015 and 2016 in English and held by 16 WorldCat member libraries worldwide

Global biodiversity is rapidly declining, resulting in far-reaching impacts on the functioning of ecosystems and human wellbeing. In recent decades, anthropogenic land use has been identified as a major driver of biodiversity loss, especially through the expansion and intensification of agricultural systems. While the drivers of biodiversity loss have been relatively clearly established, variability in the way that whole ecosystems respond to these drivers is still poorly understood. This is, in part, because we still lack a clear understanding of how species interactions govern the way tha
Using body mass, metabolism and stoichiometry to assess ecological impacts in a changing environment by Malte Jochum( )

2 editions published in 2016 in English and held by 16 WorldCat member libraries worldwide

Earth's ecosystems are composed of living organisms and their biotic and abiotic environment. In order to understand the structure and functioning of these ecosystems, ecologists study the interactions of organisms with one another and their environment. The body mass of an organism, its energy demand, and the elemental composition of the body tissue of itself and the resources it depends on are three fundamental aspects of its biology affecting its interactions with other organisms and its environment and, therefore, shaping ecological communities. While a large body of research has establ
Unravelling mechanisms linking plant diversity to plant-disease suppression by Ellen Latz( )

2 editions published in 2015 in English and held by 16 WorldCat member libraries worldwide

The use of microbes for biological control of plant diseases represents an environmentally friendly and promising approach. Plant diversity is known to increase numerous ecosystem functions and also increases the resistance of soils to pathogens by increasing the abundance of essential microbes. However, to effectively antagonize soil-borne pathogens, bacteria not only need to produce antibiotics in sufficient amounts, but also need to successfully compete for nutrients and niches on the root surface, and escape predation. However, the extent to which each of those parameters impacts rhizos
Influence of warming on microbial ecosystems by Katarina E Fussmann( )

1 edition published in 2017 in English and held by 15 WorldCat member libraries worldwide

Climate change is progressing fast causing losses in biodiversity to the extent that scientists believe the world to be on the brink of the sixth wave of mass extinction. While some global change drivers like pollution, nutrient enrichment or extended land-use on the expense of natural habitats may pose more obvious threats to ecosystems, even seemingly small changes in temperature as they are predicted for this century can have detrimental effects on populations and entire ecosystems. Temperature influences ecological processes through their underlying biological rates like metabolism, gro

This dissertation focuses on the effect of multiple global change drivers on feeding interaction strength and biodiversity loss. The mechanisms of their influences on food webs are demonstrated by simple food chain motifs and energy flow
Towards a unified allometric and stoichiometric perspective in ecology soil communities and decomposition in focus of the metabolic theory and the ecological stoichiometry by David Ott( )

2 editions published between 2014 and 2015 in English and held by 15 WorldCat member libraries worldwide

Ecosystem functioning is maintained by the interplay of a multitude of species. However, in a time of global change there are high rates of species extinctions which can drastically reduce the functionality of natural ecosystems. Consequently, a mechanistic understanding of the relationship between biodiversity and ecosystem functioning becomes increasingly important. Diversity effects are mediated by complex interactions and impact multiple levels of biological organization. Changes in consumer-resource interactions at the individual level, for example, affect population densities, spreadi
