Microbial alteration of geochemical proxies in finegrained carbonate sediments during early diagenesis
(2021-07-27)Fine-grained carbonate sediments play a crucial role in the global carbon cycle and are an exceptional record of past environmental conditions. Major paleoenvironmental constraints, derived from stable isotope and trace ... -
Microbial metabolisms and calcification in freshwater biofilms
(2008-04-18)In this study, biofilms of two CO2-degassing karst-water creeks in Germany, which attain high calcite supersaturation during their course downstream, were investigated with regard to the effects of microbial activity ... -
Microbial sulfate reduction in the tissue of the cold-water sponge Geodia barretti (Tetractinellida, Demospongiea)
(2003-06-12)Metabolic rates, community structure and the chemical micro-environment of sulfate-reducing bacteria (SRB) within the tissue of the boreal demosponge Geodia barretti were examined, and ... -
Microstructure of Gas Hydrates in Sedimentary Matrices
(2016-06-22)Gas hydrates (GH) are found worldwide in marine sediments and permafrost regions. The detection and quantification of gas hydrates present in marine sediments is crucial for safe oil and gas extraction, seafloor stability ... -
Middle-class consumers and alternative food networks in Bengaluru, India: Exploring pathways for transition to sustainable diets
(2025-01-17)The urgency for transitions toward sustainable food systems that promote and support sustainable diets is of critical importance for both planetary and human health and wellbeing. Currently, food systems are responsible ... -
Mikrobielle Diversität an diffusen Quellen des Mittel-Atlantischen Rückens
(2010-11-30)The deep sea floor forms largest associated ecosystem on earth. With it´s numerous ecological niches such as mud-volcanoes, cold seeps and hot and low-temperature influenced vents it could ... -
Mineralogical, Petrophysical and Economical Characterization of the Dimensional Stones of Uruguay; Implications for Deposit Exploration
(2012-06-05)Dimensional stones are known since the ancient world as noble mineral resources and have been used for the construction of magnificent pieces of art and architecture that were built to endure. Some examples are the Pyramids ... -
Modellierung der vegetativen Produktivität zur Bewertung der Landdegradation im ariden und semi-ariden südlichen Afrika
(2014-01-23)Dry regions as the arid southern Africa are, on the one hand, strained by unfavourable climatic conditions. On the other hand, intensive land use as rangeland and for livestock farming leads to additional encroachment of ... -
Modelling and validation of agricultural and forest biomass potentials for Germany and Austria
(2012-07-04)The Biosphere Energy Transfer Hydrology Model (BETHY/DLR), a process model that estimates the net primary productivity of agricultural and forested areas was used to assess biomass potentials for Germany and Austria. ... -
Modelling Soil Erosion, Flash Flood Prediction and Evapotranspiration in Northern Vietnam
(2016-03-08)Water-induced soil erosion (WSE) is a main factor of land degradation in many parts of the world and reported as a main threat to agriculture compared to the second largest risk by wind. Some parts of Vietnam have been ... -
Modelling the porosity loss in granular iron based permeable reactive barriers
(2022-11-24)The quality of groundwater resources globally has been under serious threat due to their exposure to a broad spectrum of anthropogenic pollutants. Permeable reactive barriers (PRBs) are an innovative technology being used ... -
Molecular and cellular differentiation during the early shell field development in Lymnaea stagnalis
(2014-02-13)Since the evolutionary emergence of the molluscan shell in the Pre-Cambrian, diverse shell forms have evolved, which are adapted to various ecological environ-ments. The innovation of the shell facilitated the vast ... -
Molecular characterisation of biomineralising genes in the freshwater pond snail Lymnaea stagnalis
(2018-06-22)Much of the evolutionary success of conchiferan molluscs can be traced back to the ability to construct a biocalcified shell that supports the soft molluscan body and offers protection from predation and desiccation. Only ... -
Monitoring forest fragmentation and carbon storage in the Cerrado Biome of Mato Grosso using optical and SAR satellite images
(2021-01-15)Several studies suggested that forest fragmentation, which is an effect of deforestation, and edge effect have an impact on the biomas and carbon stock in tropical forest. For Amazon and Atlantic Forest biomes, most studies ... -
