World System, Anthropogenic, and Ecological Threats to Bird and Mammal Species: A Structural Equation Analysis of Biodiversity Loss

Biodiversity is essential for human well-being, the functioning of ecosystems, and the sustained flow of benefits from ecosystems to individuals and societies. An important component of biodiversity is “species richness,” the number of species in an ecological unit. Loss of species richness contributes to worsening health, lower food security, and the increasing vulnerability of human and animal populations. This article examines the effects of relevant global, anthropogenic (human caused), and ecological factors on nations’ relative shares of the global total of threatened bird and mammal species for 139 countries. Using structural equation models, the authors tested hypothesized predictions from human ecology, ecological modernization, and global political-economic approaches. The findings indicate that the structure of the global system directly affects local anthropogenic factors (modernization, population), which, in concert with ecological characteristics, are direct and indirect predictors of the loss of species. This research emphasizes the importance of informed sociological analyses that account for both the direct and indirect effects of global forces and the conjoint importance of anthropogenic and ecological processes that contribute to a key form of environmental degradation.

Urbanormativity and the spatial demography of suburbia: a response to Meyer and Graybill

In their recent article in Urban Geography on “The Suburban Bias of American Society?”, William Meyer and Jessica Graybill review a number of mechanisms that enable suburbs to have advantages over ...

The Cynical Public: Claims About Science in the Discourse on Hydrofracking

This content analysis of newspaper articles and online social media from English-speaking sources on the topic of ‘fracking’ interrogates the use of scientific legitimacy in claims-makings and how public understandings of science develop through these media. In both forms of media, science is invoked in one sense as rational and objective to either neutralize or support emotionally-charged accounts and fears of hydraulic fracturing dangers. In another sense, however, science is viewed as a bureaucratic tool used at the will of government and business interests and easily corrupted to support ideological or interest-based positions. Claims regarding science typically follow ideological positions rather than the reverse - the ‘science’ that supports fracking as safe is called into question by those skeptical of fracking, while the anti-fracking position is designated as ‘anti-science’ by those who favor fracking. These strategies as they play out in the media serve to spread uncertainty, heighten cynicism, and undermine public confidence in science. An understanding of science as incomplete and cumulative, however, lends itself to the precautionary principle.
