Biological soil crusts (biocrusts) occur across most of the world's drylands and are sensitive indicators of dryland degradation. Accounting for shifts in biocrust composition is important for quantifying integrity of arid and semi-arid ecosystems, but the best methods for assessing biocrusts are uncertain. We investigate the utility of surveying biocrust morphogroups, a reduced set of biotic c...
In this paper we explore the discourses of ecology, environmental economics, new environmental pragmatism and social ecological economics as they relate to the value of ecosystems and biodiversity. Conceptualizing biodiversity and ecosystems as goods and services that can be represented by monetary values in policy processes is an economic discourse being increasingly championed by ecologists a...
We applied an Ecohealth perspective into a State of the Environment report for Grey Bruce Health Unit and summarized environmental and health data relevant for public health practice. We aimed for comprehensiveness in our data compilation, including: standard media categories (e.g., air, water, land); and ecological indicators (e.g., vectors, forests, wetlands). Data sources included both prima...
PURPOSE Simple, valid, and evidence-based indicators to measure the quality of antimicrobial prescribing in acute-care hospitals are urgently needed and increasingly requested by policymakers. The aim of this study was to develop new consensus quality indicators (QIs) for hospital antibiotic stewardship (ABS) and infection management which will be further evaluated for internal quality manageme...
BACKGROUND Ecological attributes estimated from food web models have the potential to be indicators of good environmental status given their capabilities to describe redundancy, food web changes, and sensitivity to fishing. They can be used as a baseline to show how they might be modified in the future with human impacts such as climate change, acidification, eutrophication, or overfishing. M...
James R. Karr, University of Washington Humans measure things to understand the past, to document the present, and sometimes to predict the future. But humans neither measure everything nor measure things at random. Industrialized humans measure some things because they give pleasure—batting averages of favorite baseball players, for instance—and they measure other things because they are assum...
Background and Objective: Research has shown that assessing the toxicity and ecological risk of various types of pollutants, including heavy metals, using specific indicators, is indispensable in the ecological risk assessment of the ecosystem. Accordingly, the aim of this study was the assessment of the ecological effect of heavy metals presence (Pb, Zn, Cu, Cd and, As) in Anzali wetland using...
BACKGROUND Dogs are ubiquitous in human society and attempts to manage their populations are common to most countries. Managing dog populations is achieved through a range of interventions to suit the dog population dynamics and dog ownership characteristics of the location, with a number of potential impacts or goals in mind. Impact assessment provides the opportunity for interventions to iden...
Much of the empirical data available about therapeutic alliance and its relationship to termination status come from individual psychotherapies. We know less about therapeutic alliance in couple therapy. A unique characteristic of alliance in couple or family therapy is the possibility of discrepancies in alliance between system members. In this study we sought to demonstrate three statistical ...
Ecological networks are a useful tool to study the complexity of biotic interactions at a community level. Advances in the understanding of network patterns encourage the application of a network approach in other disciplines than theoretical ecology, such as biodiversity conservation. So far, however, practical applications have been meagre. Here we present a framework for network analysis to ...
