A Comprehensive Quantitative Assessment of Bird Extinction Risk in Brazil
In an effort to avoid species loss, scientists have focused their efforts on the mechanisms making some species more prone to extinction than others. However, species show different responses to threats given their evolutionary history, behavior, and intrinsic biological features. We used bird biological features and external threats to (1) understand the multiple pathways driving Brazilian bir...
متن کاملThe Role of Quantitative Risk Assessment in Improving Hazardous Installations Siting: A Case Study
Safety distance has already been a main measurement for the hazard control of chemical installations interpreted to mean providing space between the hazardous installation and different types of targets. But, the problem is how to determine the enough space. This study considers the application of quantitative risk assessment to evaluating a compressed natural gas station site and to identi...
متن کاملSemi-quantitative risk assessment of health exposure to hazardous chemical agents in a petrochemical plant
Background: Chemical contaminants present in the work environments include gases, vapors, and solid and liquid suspended particles. The number of factories producing chemicals has increased significantly. Each year, new products are introduced into the market. Consequently, the number of employees at risk of exposure to these materials is increased. Hazardous chemicals are used in the petrochem...

SECTION 4—ASSESSMENT OF EXTINCTION RISK 4.1. Description of Extinction Risk Assessment Approaches
To assess extinction risks of loggerhead DPSs, we conducted two independent analyses. The first analysis used the diffusion approximation approach based on time series of counts of nesting females or nests (Lande and Orzack 1988, Dennis et al. 1991, Holmes 2001, Snover and Heppell 2009). This analysis provided a metric (susceptibility to quasi-extinction or SQE) to determine if the probability ...
