Description

The sustainability of some species is at risk as a result of anthropogenic influences such as climate change and harvest. This study focused on the combined role of economic and ecological factors that can lead to overharvesting of commercial marine species and aimed to understand the relationship between ecological extinction risk, biological productivity, and economic value. We used existing economic, ecological, and extinction risk data and compiled it for use in the analysis. We focused on maximum sustainable yield as an indicator of productivity, economic data that indicated the landed value of a species, and International Union for the Conservation of Nature (IUCN) species status as an indicator of extinction risk. We related economic and ecological production to IUCN risk factor to determine if value and productivity determined risk. Overall results from analyses indicate that species with very different productivity and economic value characteristics can have similar extinction risk. However, this can vary depending on the analyses performed and could also vary by factors not assessed in this study such as management scheme, climate impacts, or intensity of the fishery. Future work will focus on more quantitative analyses and comparing the results to risk models.

Quantifying Extinction Risk in Commercial Marine Species

The sustainability of some species is at risk as a result of anthropogenic influences such as climate change and harvest. This study focused on the combined role of economic and ecological factors that can lead to overharvesting of commercial marine species and aimed to understand the relationship between ecological extinction risk, biological productivity, and economic value.
