  • Our understanding of ice algal responses to the recent changes in Arctic sea ice is impeded by limited field observations. In the present study, environmental characteristics of the landfast sea-ice zone as well as primary production and macromolecular composition of ice algae and phytoplankton were studied in the Kitikmeot Sea near Cambridge Bay in spring 2017. Averaged total chlorophyll-a (Chl-a) concentration was within the lower range reported previously for the same region, while daily carbon uptake rates of bottom-ice algae were significantly lower in this study than previously reported for the Arctic. Based on various indicators, the region's low nutrient concentrations appear to limit carbon uptake rates and associated accumulation of bottom-ice algal biomass. Furthermore, the lipids-dominant biochemical composition of bottom-ice algae suggests strong nutrient limitation relative to the distinctly different carbohydrates-dominant composition of phytoplankton. Together, the results confirm strong nitrate limitation of the local marine system.

  • Focused and results-based, this important board review title covers everything that residents need to know when preparing for their Anesthesiology BASIC exam. Written by residents familiar with the exam, its use of bullet points and illustrations enables effective learning and efficient exam preparation. Providing a comprehensive review of all exam topics, the guide uses a clear and focused note-taking style to present 'high-yield' information, enabling efficient study techniques. Bullet points and short paragraphs feature to help rapid understanding, with margin space provided to annotate and add further notes. The helpful format ensures that all exam preparation, including notes from question banks, can be kept in this 'one-stop' review book. Mirroring the BASIC exam requirements, this book covers clinical anesthetic practice, pharmacology, physiology, anatomy, and anesthesia equipment and monitoring. Written by residents for residents, it is an essential preparation resource for the Anesthesiology BASIC exam.
