Autotrophy of the Other: On Food and Hospitality
<p>The book is, as the title suggests, about food and hospitality, and the way that plants make both of them possible. It argues that the history of western philosophy -- from its conceptions of the soul, of politics, of the home, etc. -- has worked to veil and occlude the existence of plants, and …

Effects of Anthropogenic Urea on Lakes of the North American Great Plains: Ecological Implications Based on Experimental and Observational Studies
… < 3 mg N L-1 may rapidly enhance net autotrophy, while urea additions > 5 mg N L-1 decreasingly favor net autotrophy. Together, these results suggest that the expected 100 million metric ton increase in urea use by ~2050 is likely to alter global N biogeochemistry, ecosystem …

Investigating the ecology of partial and full myco-heterotrophy among Orchidaceae and Ericaceae using the stable isotope natural abundance analysis approach
… among terrestrial members of the Orchidaceae: autotrophy, where green orchids have carbon isotope signatures indistinguishable from those of surrounding autotrophs and mainly associate with Rhizoctonia species; partial myco-heterotrophy, where green orchids have carbon isotope signatures …

Productivity, metabolism and physiology of free-living chemoautotrophic Epsilonproteobacteria
… into the core biochemical reactions underlying autotrophy in Epsilonprotebacteria, a theoretical metabolic model of Sulfurimonas denitrificans was developed. Validated iteratively by comparing in silico yields with data from chemostat experiments, the model generated hypotheses explaining …

Plastid Genome Evolution in the Parasitic Genera Cuscuta (Convolvulaceae) and Krameria (Krameriaceae)
… an additional independent transition from autotrophy to heterotrophy. In chapter 5, I assembled the plastid genome of one Krameria species and analyzed it along with two previously reported plastid genomes from the group. I found that these species exhibit sweeping retention of plastid …

Latitudinal variation in plankton size spectra along the Atlantic Ocean

Bridging the physiology and ecology of hemiparasitic plants
… All lineages that have evolved away from autotrophy display profound changes in morphological, biochemical, and molecular traits. In addition, the adoption of a parasitic lifestyle necessitates certain physiological adaptations that allow the parasite to locate, attach to, and effectively …

Carbon metabolism and dissolved organic carbon (DOC) fluxes on seagrass communities: insights from plant colonization states, eutrophication and global change related factors
… and the seagrass Cymodocea nodosa moved from autotrophy to heterotrophy in certain seasons of the year and could increase or decrease the DOC release. The response of seagrass communities when subjected to a pH decrease was complex and showed to be species-specific. The pH decrease triggered a …

Response and resilience of estuarine benthic ecosystems to anthropogenic pressures
… reduced negative effects on function (e.g. net autotrophy occurred at higher levels of organic enrichment in CaCO₃-treated plots than controls (1400 vs 950 g dw m-2)). This study represents a crucial step forward in understanding the ecological effects of coastal acidification and the role of …

Zur Struktur und Funktion regulatorischer Elemente des cbb-Regulons in Ralstonia eutropha
Für die autotrophe Assimilation von CO2 benötigt Ralstonia eutropha H16 die Enzyme des Calvin-Cyclus. Die genetische Kontrolle bei der wechselseitigen Umstellung des Kohlenstoffmetabolismus zwischen autotrophen und heterotrophen Bedingungen betrifft vorrangig die Transkription der cbb-Operone, …

Import and decomposition of dissolved organic carbon in pre-dams of drinking water reservoirs
Dissolved organic carbon (DOC) depicts a key component in the aquatic carbon cycle as well as for drinking water production from surface waters. DOC concentrations increased in water bodies of the northern hemisphere in the last decades, posing ecological consequences and water quality problems. …
