Microbial ecology is flourishing, and in the process, is making contributions to how the ecology and biology of large organisms is understood. Ongoing advances in sequencing technology and computational methods have enabled the collection and analysis of vast amounts of molecular data from diverse biological communities. While early studies focused on cataloguing microbial biodiversity in environments ranging from simple marine ecosystems to complex soil ecologies, more recent research is concerned with community functions and their dynamics over time. Models and concepts (...) from traditional ecology have been used to generate new insight into microbial communities, and novel system-level models developed to explain and predict microbial interactions. The process of moving from molecular inventories to functional understanding is complex and challenging, and never more so than when many thousands of dynamic interactions are the phenomena of interest. We outline the process of how epistemic transitions are made from producing catalogues of molecules to achieving functional and predictive insight, and show how those insights not only revolutionize what is known about biological systems but also about how to do biology itself. Examples will be drawn primarily from analyses of different human microbiota, which are the microbial consortia found in and on areas of the human body, and their associated microbiomes (the genes of those communities). Molecular knowledge of these microbiomes is transforming microbiological knowledge, as well as broader aspects of human biology, health and disease. (shrink)

Native American land ethics are not well understood by many governmental natural resource managers. This article presents the results of interviews with selected tribal elders, tribal land managers, and tribal content experts concerning traditional beliefs and values forming a land ethic and how these influence tribal land management practices. The Native American land ethic that emerged from this study includes four belief areas: “All Is Sacred”; ; “Right Action”; ; “All Is Interrelated”; ; and “Mother Earth”;. Traditional Native American beliefs (...) concerning the environment appear to spring from a spiritual context rather than the scientific‐utilitarian context more prevalent in the dominant Euro‐American culture.

Online support groups are common sources of both health information and social support. To augment existing qualitative understandings of member roles and identities in OSGs, this article presents a corpus-based investigation of shifts in member lexicogrammatical and discourse-semantic choices in a bipolar disorder OSG. In total, 8.4 million words in 57,000 posts were transformed into a structured, grammatically annotated corpus and investigated using systemic functional linguistics as a theoretical framework, focusing on interpersonal and experiential meanings. The findings of mood and (...) transitivity analyses show marked differences between new and veteran members’ language choices over the course of membership in the OSG: particularly, in how veteran members provide advice, and in how new and veteran members ascribe and attribute bipolar disorder to both the self and others. Discussion addresses the affordances and limitations of corpus linguistics and SFL as strategies for providing quantitative support for key claims of earlier research in this field. (shrink)
