Meeting: Physiological Responses to Multiple Stressors in a Changing Climate, A symposium for the 2013 SICB annual meeting in San Francisco, CA

全球各地的栖息地正日益受到人为活动的影响，这些活动改变了气候，引入了物种，并增加了污染。了解全球变化对生物分布和丰度的影响是综合生物生物学的前沿。长期以来，致力于了解生物和非生物栖息地变化如何影响生物分布的生物学家一直使用精心控制的实验室实验，这些实验操纵单一环境变量（如栖息地温度）来确定生物性能的某些方面（如温度耐受性）。这些性能参数随后被用来推断生态反应。生理学家所做的大多数研究一次只检查一个环境变量，然而在自然界中，生物体同时暴露于多种类型的环境变量，包括可能影响生物体不同生理系统的栖息地变化。为了正确地将生态响应与多个栖息地特征的同时变化联系起来，了解这些环境变量的多重变化对性能是否具有加性、拮抗性或非线性协同效应是一个关键问题。这笔资金将用于资助在旧金山举行的2013年综合与比较生物学学会会议上的一个研讨会，该研讨会将重点关注生理学研究，同时检查多种环境变量，以测试加性-拮抗-协同反应的可能性。通过汇集领先的研究人员，pi希望建立必要的后续步骤，以提高我们预测生物体如何应对多元变化环境的能力。预计本次研讨会将在积极研究对多元环境的生理反应的研究人员之间建立新的合作关系，并扩大进行此类研究的研究人员的数量。研讨会的演讲者从事昆虫、爬行动物、淡水和海洋鱼类以及海洋无脊椎动物的研究，并研究环境变量，包括温度、氧气、酸化、盐度、干燥、海拔、纬度、污染、疾病和物理强迫（流/湍流）。私人顾问将向所有研讨会参与者强调招募代表性不足的少数民族参与者。将向资历较浅的同事提供旅费奖励，以支持他们参加与研讨会有关的论文会议。报告手稿将发表在SICB期刊综合与比较生物学（http://icb.oxfordjournals.org/）上。

Habitats around the globe are increasingly impacted by anthropogenic activities that alter the climate, introduce species, and increase pollution. Understanding the impacts of global change on the distribution and abundance of organisms in the context of their habitats is at the forefront of integrative organismal biology. Biologists working to understand how the distribution of organisms will be impacted by biotic and abiotic habitat changes have long used carefully controlled laboratory experiments that manipulate a single environmental variable (e.g., habitat temperature) to determine some aspect of organismal performance (e.g., temperature tolerance). Those performance parameters are subsequently used to infer ecological responses. The majority of studies done by physiologists examine one environmental variable at a time, yet in nature organisms are simultaneously exposed to multiple types of environmental variables, including habitat shifts that may affect different physiological systems within an organism. Whether those multiple shifts in environmental variables have an additive, an antagonistic, or a non-linear synergistic effect on performance is a critical issue to understand in order to properly link ecological responses to simultaneous shifts in multiple habitat characteristics. This grant will fund a symposium at the 2013 Society for Integrative and Comparative Biology meeting in San Francisco that will focus on physiological studies where multiple environmental variables are simultaneously examined to test the additive-antagonistic-synergistic response possibilities. By bringing together leading researchers, the PIs hope to establish the necessary next steps to increase our ability to predict how organisms respond to a multivariate changing environment. It is expected that this symposium will establish novel collaborations among researchers actively investigating physiological responses to a multivariate environment, and broaden the number of researchers conducting such studies. Speakers in the symposium are engaged in research on insects, reptiles, freshwater and marine fish, and marine invertebrates, and study environmental variables including temperature, oxygen, acidification, salinity, desiccation, altitude, latitude, pollution, disease, and physical forcing (flow/turbulence). Recruitment of underrepresented minority participants will be emphasized by the PIs to all of the symposium participants. Merit-based travel awards will be provided to junior colleagues to support their participation in a contributed paper session linked to the symposium. Presentation manuscripts will be published in the SICB journal Integrative and Comparative Biology (http://icb.oxfordjournals.org/).
