The aim of this study is to develop a better understanding of the complex processes by which fish in the subfamily Gadinae respond to changes in their environment. Gadinae is a group of marine fish that includes several species of economic importance (e.g. Alaska pollock, Atlantic cod, Pacific cod). Species in this group have already displayed some evidence of geographic range alteration as a result of climate change. By integrating information on the genetic relationships among gadine fishes, their distributions, and climate data, this study will reconstruct the evolution of suitable habitat characteristics for the group. Understanding how suitable habitats for these species have evolved is key to predicting their fate when faced with climate change. This information, in turn, is applicable to the development of natural resource management policies for adaptation and mitigation of climate change effects on economically important fisheries. This project will also fund two undergraduate research assistants, training them in geographic information systems analysis techniques. The skills they develop in the course of this research are applicable not only to scientific research and resource management, but to developing public health, conservation, and climate change management and mitigation strategies.

这项研究的目的是更好地了解Gadinae亚科鱼类对环境变化的复杂反应过程。Gadinae是一组海洋鱼类，包括几个具有重要经济价值的物种(例如阿拉斯加鳕鱼、大西洋鳕鱼、太平洋鳕鱼)。这一组中的物种已经显示出一些证据表明，由于气候变化，地理范围发生了变化。通过整合鱼类之间的遗传关系、它们的分布和气候数据，这项研究将重建该群体适宜栖息地特征的演变。了解这些物种的适宜栖息地是如何演变的，是预测它们在面临气候变化时命运的关键。反过来，这些信息也适用于制定自然资源管理政策，以适应和减轻气候变化对重要经济渔业的影响。该项目还将资助两名本科生研究助理，对他们进行地理信息系统分析技术培训。他们在研究过程中培养的技能不仅适用于科学研究和资源管理，而且适用于制定公共卫生、保护和气候变化管理和缓解战略。
