** New this week ** Effects of Temperature on Fish Sex Determination: Potential Bioindictators of Global Climate Change, November 1, 2018 (Webinar). This is part of the OneNOAA Science Seminar Series. Sex determination in several fishes such as those from Atheriniform families is strongly dependent on the water temperature experienced during early life (so-called temperature-dependent sex determination or TSD). In recent years, water temperature change due to climate change has been concerning on a world-wide level. Fish that have TSD are expected to be seriously affected (e.g. extreme unbalanced sex ratios). Our recent studies have shown that some Atheriniform species possess a major, if not master, testis determining gene, the Y-chromosome-linked anti-Müllerian hormone (amhy). This discovery now makes it possible to detect mismatches (sex reversals) between genotypic (XX or XY) and phenotypic (ovary or testis) sex and demonstrate effects of temperatures on sex determination in wild populations. Using such high temperature sensitivity in sex determination/differentiation and the Y-chromosome linked gene marker, we have been working to establish Atheriniform fish species as bioindicators for the impacts of global warming/climate change on fish reproduction worldwide.

 Is the Arctic Set to Become a Main Shipping Route? Could it herald an era of more cargo shipping around the top of the world? Back in the 19th Century there was a race to map and navigate the Northwest Passage through the Arctic Ocean as a shortcut between the North Atlantic and North Pacific. Explorers would take ships up Greenland's west coast, then try to weave through Canada's Arctic islands, before going down the Bering Strait between Alaska and Russia. BBC News Countries Urge Increased International Research in the Arctic. Ministers from 18 nations and representatives from Arctic indigenous groups on Friday called for increased efforts for international scientific collaboration in the Arctic. The officials also acknowledged the effects of global warming in the rapidly changing Arctic through a joint statement joint statement. However, the statement sidestepped attributing the warming to human activities. "We strongly note the need for increased effort and urgent attention supporting further international scientific collaboration focusing on the warming trend in the Arctic," conveys the nonbinding joint statement, issued following the second Arctic Science Ministerial meeting. EOS  Climate Change and the Arctic: University of Alberta to Host French Reps at Roundtable Focusing on Polar Regions.

** New this week ** Coastal Wetlands Reduce Disaster Risk, Protect Biodiversity, and Promote Human Health and Well-Being, November 6, 2018 (Webinar). This is part of the OneNOAA Science Seminar Series. There is substantial, growing literature that details positive human health effects, psychological and physiological, of exposure to "nature," including "green" and "blue space," with evidence suggesting that diversity of species or environments may have specific positive human health benefits. These health benefits are important ecosystem services provided by healthy ecosystems. In this presentation, we discuss several critical ecosystem services provided by wetlands including disaster risk reduction, with an emphasis on benefits to human health and well-being. Impacts to human health via damage to ecosystem services from disasters have rarely been considered in disaster planning or mitigation, nor have the health benefits been part of the framework for planning urban greenspaces and land-use. Coastal wetlands can be part of "natural and nature-based" solutions, minimizing the impacts of disasters by buffering coastal communities from storms and erosion and absorbing flood waters. In addition, mental and physical health benefits of experiencing healthy wetlands could offset some stress and disease encounters related to disasters.
** New this week ** Northern rock sole recruitment response to winds and temperature in the eastern Bering Sea, November 7, 2018 (Webinar).
