项目摘要

The endangered St. Lawrence Estuary beluga (Delphinapterus leucas) inhabits a marine ecosystem greatly impacted by upstream anthropogenic activities. This small population of around 900 individuals has not shown any sign of recovery in the past decades. An increase in the number of post-partum females and calves mortality has even been observed in recent years. The high contaminant exposure of belugas was suggested as one important threat to the health of belugas and the recovery of this population. Understanding the exposure of belugas to known and new contaminants as well as their possible exposure-related effects are key elements to ensure the conservation of this southernmost beluga population. This project will contribute to dress a global picture of the concentrations, trophic transfer and distribution of contaminants of priority concern in tissues of belugas. A general screening of all chemicals found in tissues will also be developed and analyzed to identify any new substances of interest using innovative non-targeted methods. Innovative new proteomic and transcriptomic techniques will be used to determine biological pathways that may be impacted by exposure to environmental contaminants in addition to a series of targeted health variables. Relationships between contaminant concentrations and biological endpoints will also be conducted in order to better understand the potential effects of the chemical exposure. In vitro testing and modelling will complete this research to evaluate biological effects of contaminants in beluga. Results generated from this project will help fill critical knowledge gaps on environmental contaminants and their potential effects in the SLE beluga population. The information will support the decision-making, management and conservation strategies of this unique beluga whale population. The multi-disciplinary and diversified expert team will be training the next generation of marine mammal and environmental toxicology specialists.
濒临灭绝的圣劳伦斯河口白鲸(Delphinapterus leucas)广泛栖息在海洋生态系统中 受到上游人类活动的影响。这只约900只的小种群没有显示出 在过去的几十年里,任何复苏的迹象。产后母畜和幼仔数量增加 近年来甚至出现了死亡现象。白鲸的高污染暴露被认为是 这是对白鲸的健康和种群恢复的一个重要威胁。了解暴露于 对已知和新的污染物以及它们可能产生的与捕捞有关的影响的影响是关键因素, 确保保护最南端的白鲸种群该项目将有助于服装全球 组织中优先关注的污染物的浓度、营养转移和分布图 白鲸还将对组织中发现的所有化学物质进行一般筛选和分析, 使用创新的非靶向方法检测任何感兴趣的新物质。创新的新型蛋白质组学和 转录组学技术将用于确定可能受到暴露影响的生物途径, 环境污染物以及一系列有针对性的健康变量。之间的关系 污染物浓度和生物终点也将进行,以更好地了解 化学品暴露的潜在影响。体外测试和建模将完成这项研究,以评估 污染物对白鲸的生物影响。从这个项目产生的结果将有助于填补关键 关于环境污染物及其对SLE白鲸种群的潜在影响的知识差距。的 信息将支持这一独特白鲸的决策、管理和保护战略 鲸鱼种群多学科和多元化的专家团队将培养下一代 海洋哺乳动物和环境毒理学专家。
