  abstract  = {Despite more than half a century of hominin fossil discoveries in eastern Africa, the regional environmental context of hominin evolution and dispersal is not well established due to the lack of continuous palaeoenvironmental records from one of the proven habitats of early human populations, particularly for the Pleistocene epoch. Here we present a 620,000-year environmental record from Chew Bahir, southern Ethiopia, which is proximal to key fossil sites. Our record documents the potential influence of different episodes of climatic variability on hominin biological and cultural transformation. The appearance of high anatomical diversity in hominin groups coincides with long-lasting and relatively stable humid conditions from similar to 620,000 to 275,000 years bp (episodes 1-6), interrupted by several abrupt and extreme hydroclimate perturbations. A pattern of pronounced climatic cyclicity transformed habitats during episodes 7-9 (similar to 275,000-60,000 years bp), a crucial phase encompassing the gradual transition from Acheulean to Middle Stone Age technologies, the emergence of Homo sapiens in eastern Africa and key human social and cultural innovations. Those accumulative innovations plus the alignment of humid pulses between northeastern Africa and the eastern Mediterranean during high-frequency climate oscillations of episodes 10-12 (similar to 60,000-10,000 years bp) could have facilitated the global dispersal of H. sapiens.},

  abstract  = {Under ongoing climate change and increasing anthropogenic activity, which continuously challenge ecosystem resilience, an in-depth understanding of ecological processes is urgently needed. Lakes, as providers of numerous ecosystem services, face multiple stressors that threaten their functioning. Harmful cyanobacterial blooms are a persistent problem resulting from nutrient pollution and climate-change induced stressors, like poor transparency, increased water temperature and enhanced stratification. Consistency in data collection and analysis methods is necessary to achieve fully comparable datasets and for statistical validity, avoiding issues linked to disparate data sources. The European Multi Lake Survey (EMLS) in summer 2015 was an initiative among scientists from 27 countries to collect and analyse lake physical, chemical and biological variables in a fully standardized manner. This database includes in-situ lake variables along with nutrient, pigment and cyanotoxin data of 369 lakes in Europe, which were centrally analysed in dedicated laboratories. Publishing the EMLS methods and dataset might inspire similar initiatives to study across large geographic areas that will contribute to better understanding lake responses in a changing environment.},

  abstract  = {Surface lake sediments, 28 from Hoh Xil, 24 from northeastern China, 99 from Lake Bosten, 31 from Ulungur and 26 from Heihai were collected to determine C-13 and O-18 values. Considering the impact factors, conductivity, alkalinity, pH, TOC, C/N and carbonate-content in the sediments, Cl, P, S, and metal element ratios of Mg/Ca, Sr/Ca, Fe/Mn of bulk sediments as environmental variables enable evaluation of their influences on C-13 and O-18 using principal component analysis (PCA) method. The closure and residence time of lakes can influence the correlation between C-13 and O-18. Lake water will change from fresh to brackish with increasing reduction and eutrophication effects. Mg/Ca in the bulk sediment indicates the characteristic of residence time, Sr/Ca and Fe/Mn infer the salinity of lakes. Carbonate formation processes and types can influence the C-13-O-18 correlation. O-18 will be heavier from Mg-calcite and aragonite formed in a high-salinity water body than calcite formed in freshwater conditions. When carbonate content is less than 30\%, there is no relationship with either C-13 or O-18, and also none between C-13 and O-18. More than 30\%, carbonate content, however, co-varies highly to C-13 and O-18, and there is also a high correlation between C-13 and O-18. Vegetation conditions and primary productivity of lakes can influence the characteristics of C-13 and O-18, and their co-variance. Total organic matter content (TOC) in the sediments is higher with more terrestrial and submerged plants infilling. In northeastern and northwestern China, when organic matter in the lake sediments comes from endogenous floating organisms and algae, the C-13 value is high. C-13 is in the range of -4\%o to 0 parts per thousand when organic matter comes mainly from floating organisms (C/N<6); in the range of -4 parts per thousand to 8 parts per thousand when organic matter comes from diatoms (C/N=6 to 8); and -8 parts per thousand to -4 parts per thousand when organic matter comes from aquatic and terrestrial plants (C/N>8).},

  abstract  = {Gew{\"a}sser werden traditionellerweise als abgeschlossene {\"O}kosysteme gesehen, und insbeson¬dere das Zirkulieren von Wasser und N{\"a}hrstoffen im Pelagial von Seen wird als Beispiel daf{\"u}r angef{\"u}hrt. Allerdings wurden in der j{\"u}ngeren Vergangenheit wichtige Verkn{\"u}pfungen des Freiwasserk{\"o}rpers von Gew{\"a}ssern aufgezeigt, die einerseits mit dem Benthal und andererseits mit dem Litoral, der terrestrischen Uferzone und ihrem Einzugsgebiet bestehen. Dadurch hat in den vergangen Jahren die horizontale und vertikale Konnektivit{\"a}t der Gew{\"a}sser{\"o}kosysteme erh{\"o}htes wissenschaftliches Interesse auf sich gezogen, und damit auch die {\"o}kologischen Funktionen des Gew{\"a}ssergrunds (Benthal) und der Uferzonen (Litoral). Aus der neu beschriebenen Konnektivit{\"a}t innerhalb und zwischen diesen Lebensr{\"a}umen ergeben sich weitreichende Konsequenzen f{\"u}r unser Bild von der Funktionalit{\"a}t der Gew{\"a}sser. In der vorliegenden Habilitationsschrift wird am Beispiel von Fließgew{\"a}ssern und Seen des nordostdeutschen Flachlandes eine Reihe von internen und externen funktionalen Verkn{\"u}pfungen in den horizontalen und vertikalen r{\"a}umlichen Dimensionen aufgezeigt. Die zugrunde liegenden Untersuchungen umfassten zumeist sowohl abiotische als auch biologische Variablen, und umfassten thematisch, methodisch und hinsichtlich der Untersuchungsgew{\"a}sser ein breites Spektrum. Dabei wurden in Labor- und Feldexperimenten sowie durch quantitative Feldmes¬sungen {\"o}kologischer Schl{\"u}sselprozesse wie N{\"a}hrstoffretention, Kohlenstoffumsatz, extrazellu¬l{\"a}re Enzymaktivit{\"a}t und Ressourcenweitergabe in Nahrungsnetzen (mittels Stabilisotopen¬methode) untersucht. In Bezug auf Fließgew{\"a}sser wurden dadurch wesentliche Erkenntnisse hinsichtlich der Wirkung einer durch Konnekticit{\"a}t gepr{\"a}gten Hydromorphologie auf die die aquatische Biodiversit{\"a}t und die benthisch-pelagische Kopplung erbracht, die wiederum einen Schl{\"u}sselprozess darstellt f{\"u}r die Retention von in der fließenden Welle transportierten Stoffen, und damit letztlich f{\"u}r die Produktivit{\"a}t eines Flussabschnitts. Das Litoral von Seen wurde in Mitteleuropa jahrzehntelang kaum untersucht, so dass die durchgef{\"u}hrten Untersuchungen zur Gemeinschaftsstruktur, Habitatpr{\"a}ferenzen und Nahrungs¬netzverkn{\"u}pfungen des eulitoralen Makrozoobenthos grundlegend neue Erkenntnisse erbrach¬ten, die auch unmittelbar in Ans{\"a}tze zur {\"o}kologischen Bewertung von Seeufern gem{\"a}ß EG-Wasserrahmenrichtlinie eingehen. Es konnte somit gezeigt werden, dass die Intensit{\"a}t sowohl die internen als auch der externen {\"o}kologischen Konnektivit{\"a}t durch die Hydrologie und Morphologie der Gew{\"a}sser sowie durch die Verf{\"u}gbarkeit von N{\"a}hrstoffen wesentlich beeinflusst wird, die auf diese Weise vielfach die {\"o}kologische Funktionalit{\"a}t der Gew{\"a}sser pr{\"a}gen. Dabei tr{\"a}gt die vertikale oder horizontale Konnektivit{\"a}t zur Stabilisierung der beteiligten {\"O}kosysteme bei, indem sie den Austausch erm{\"o}glicht von Pflanzenn{\"a}hrstoffen, von Biomasse sowie von migrierenden Organismen, wodurch Phasen des Ressourcenmangels {\"u}berbr{\"u}ckt werden. Diese Ergebnisse k{\"o}nnen im Rahmen der Bewirtschaftung von Gew{\"a}ssern dahingehend genutzt werden, dass die Gew{\"a}hrleistung horizontaler und vertikaler Konnektivit{\"a}t in der Regel mit r{\"a}umlich komplexeren, diverseren, zeitlich und strukturell resilienteren sowie leistungsf{\"a}hi¬geren {\"O}kosystemen einhergeht, die somit intensiver und sicherer nachhaltig genutzt werden k{\"o}nnen. Die Nutzung einer kleinen Auswahl von {\"O}kosystemleistungen der Fl{\"u}sse und Seen durch den Menschen hat oftmals zu einer starken Reduktion der {\"o}kologischen Konnektivit{\"a}t, und in der Folge zu starken Verlusten bei anderen {\"O}kosystemleistungen gef{\"u}hrt. Die Ergebnisse der dargestellten Forschungen zeigen auch, dass die Entwicklung und Implementierung von Strategien zum integrierten Management von komplexen sozial-{\"o}kologischen Systemen wesentlich unterst{\"u}tzt werden kann, wenn die horizontale und vertikale Konnektivit{\"a}t gezielt entwickelt wird.},
