Redefining Nature: Ecology, Culture and Domestication. Roy Ellen and Katsuyoshi Fukui. eds. Oxford: Oxford International Publishers Ltd., 1996.664 pp.

"Understanding Nature is a new kind of ecology textbook: a straight-forward resource that teaches natural history and ecological content, and a way to instruct students that will nurture both Earth and self. While meeting the textbook guidelines set forth by the Ecological Society of America, Understanding Nature has a unique ecotherapy theme, using a historical framework to teach ecological theory to undergraduates. This textbook presents all the core information without being unnecessarily wordy or lengthy, using simple, relatable language and discussing ecology in ways that any student can apply in real life. Uniquely, it is also a manual on how to improve one's relationship with the Earth. This is accomplished through coverage of natural history, ecology, and applications, together with suggested field activities that start each chapter and thinking questions that end each chapter. The book includes traditional ecological knowledge as well as the history of scientific ecological knowledge. Understanding Nature teaches theory and applications that will heal the Earth. It also teaches long-term sustainability practices for one's psyche. Professor Louise Weber is both an ecologist and a certified ecopsychologist, challenging ecology instructors to rethink what and how they teach about nature. Her book bridges the gap between students taking ecology to become ecologists and those taking ecology as a requirement, who will use the knowledge to become informed citizens"--

The role of soil biodiversity in regulating multiple ecosystem functions is poorly understood, limiting our ability to predict how soil biodiversity loss might affect human wellbeing and ecosystem sustainability. Here, combining a global observational study with an experimental microcosm study, we provide evidence that soil biodiversity (bacteria, fungi, protists and invertebrates) is significantly and positively associated with multiple ecosystem functions. These functions include nutrient cycling, decomposition, plant production, and reduced potential for pathogenicity and belowground biological warfare. Our findings also reveal the context dependency of such relationships and the importance of the connectedness, biodiversity and nature of the globally distributed dominant phylotypes within the soil network in maintaining multiple functions. Moreover, our results suggest that the positive association between plant diversity and multifunctionality across biomes is indirectly driven by soil biodiversity. Together, our results provide insights into the importance of soil biodiversity for maintaining soil functionality locally and across biomes, as well as providing strong support for the inclusion of soil biodiversity in conservation and management programmes. Combining field data from 83 sites on five continents, together with microcosm experiments, the authors show that nutrient cycling, decomposition, plant production and other ecosystem functions are positively associated with a higher diversity of a wide range of soil organisms. ; Marie Sklodowska-Curie ; We thank N.

Within anthropological research, there has been a long process of interaction and transformation between the modern and dichotomized notion of nature and hybrid notions of quasi-objects and quasi-humans. This has transformed the conception of nature as an apolitical entity to that of a cultural construct with political implications. This is a theoretical review of the implied transformations within anthropological categories and research in relation to nature, ecology and environment. Two tendencies are noted. The first is related to rethinking the conception of a nature/culture duality in the light of local knowledge, and the second is related to the contributions of political ecology and the role of various social actors within the environmental discourses. Finally there is a presentation of the perspectives in anthropological research in relation to nature, ecology and environment in Colombia and Latin America. ; En las investigaciones antropológicas ha habido un largo proceso de transformación e interacción de la noción moderna de la naturaleza con nociones híbridas de cuasi-objetos y cuasi-humanos, así como la transformación de las concepciones de la naturaleza de una entidad apolítica a construcciones sociales con implicaciones políticas. Para analizar estos procesos, este texto presenta una revisión teórica de los cambios que se han dado en las categorías e investigaciones antropológicas sobre naturaleza, ecología y medio ambiente. Se destacan dos tendencias: la primera, ligada al replanteamiento de la dicotomía naturaleza/cultura a la luz de los conocimientos locales. La segunda, relacionada con los aportes de la ecología política, enfatizando el papel de los diferentes actores dentro de los discursos ambientales. Finalmente, se contextualizan las perspectivas de investigación sobre naturaleza, ecología y medio ambiente en América latina y en Colombia.

Direct quantification of terrestrial biosphere responses to global change is crucial for projections of future climate change in Earth system models. Here, we synthesized ecosystem carbon-cycling data from 1,119 experiments performed over the past four decades concerning changes in temperature, precipitation, CO2 and nitrogen across major terrestrial vegetation types of the world. Most experiments manipulated single rather than multiple global change drivers in temperate ecosystems of the USA, Europe and China. The magnitudes of warming and elevated CO2 treatments were consistent with the ranges of future projections, whereas those of precipitation changes and nitrogen inputs often exceeded the projected ranges. Increases in global change drivers consistently accelerated, but decreased precipitation slowed down carbon-cycle processes. Nonlinear (including synergistic and antagonistic) effects among global change drivers were rare. Belowground carbon allocation responded negatively to increased precipitation and nitrogen addition and positively to decreased precipitation and elevated CO2. The sensitivities of carbon variables to multiple global change drivers depended on the background climate and ecosystem condition, suggesting that Earth system models should be evaluated using site-specific conditions for best uses of this large dataset. Together, this synthesis underscores an urgent need to explore the interactions among multiple global change drivers in under-represented regions such as semi-arid ecosystems, forests in the tropics and subtropics, and Arctic tundra when forecasting future terrestrial carbon-climate feedback. ; National Natural Science Foundation of ChinaNational Natural Science Foundation of China [31430015, 31830012]; US NSFNational Science Foundation (NSF) [DEB-0955771]; ClimMani COST actionEuropean Cooperation in Science and Technology (COST) [ES1308] ; We thank J.
