Investigations into the cause of this downward trend have focused on many different possible factors. Toxicity caused by the accumulation of organochlorines (OCs), such as polychlorinated biphenyls (PCBs) and l,l,l-trichloro-2,2-bis(p-chlorophenyl)ethane or dichlorodiphenyltrichloroethane (DDT), has been demonstrated in marine mammals and was considered here as one possible factor that may have contributed to the decline of Steller sea lions or their failure to recover. The focus of this project was to investigate the relationship of contaminant loads to hormone levels, specifically thyroid hormones and cortisol in Steller sea lions. Two approaches were taken to this study. Firstly, baseline hormone concentrations were identified for the thyroid hormones, thyroxine (T4) and triiodothyronine (T3), and cortisol. This involves comparison and extrapolation. Secondly, possible risk effects were examined by comparing levels of OCs in captive and free-ranging Steller sea lions to known effects in related species with known physiological thresholds. Serum concentrations of total 4T were highest in Steller sea lions followed by total T3 concentrations. Concentrations of free4 Tand free T 3 were three to four orders of magnitude lower. Concentrations for all four thyroid hormone measurements tended to a lower level as animals matured beyond the neonatal stage. When thyroid hormones from captive sea lions were evaluated across seasons, all thyroid hormones were highest in the July to September period. Cortisol concentrations were similar in male and female pups. Cortisol varied with age but when considered in regards to time of year when sampled, followed a seasonal pattern. Cortisol was elevated in fall months in captive sea lions (non-pups), which is similar to what is seen in other marine mammals and is likely associated with the annual molt. Male pups from Alaska had lower levels of £PCBs and £DDT when compared to male pups from Russia. Female pups from Alaska were significantly lower in £PCBs than Russian female pups as were female pups for £DDT levels between areas. Anywhere from 12 to 64% (depending on rookery) of Steller sea lion pups investigated for contaminants had concentrations of £PCBs that are high enough to cause physiological problems. Concentrations in blood taken monthly for 2 years in three captive Steller sea lions were similar at any given sampling time and followed a seasonal pattern with levels significantly higher in the summer months of July to September and lower in the three month winter period January to March. Concentrations of OCs in blubber samples collected quarterly for the captive females followed an analogous pattern to blood samples but the captive male sea lion was considerably lower and declined over the study period. A significant relationship- between blubber contaminants and lipids was noted in the three captive Steller sea lions. Even though OC contamination has not been hypothesized to be the primary factor that precipitated the population decline, there is a potential for these chemicals to have a negative effect on the health of free-ranging Steller sea lions. These data suggest that concentrations of OCs in Steller sea lions may be high enough to cause endocrine or reproductive dysfunction and could potentially impact fertility or fecundity. Therefore, OC contaminants can not be dismissed as a contributing source to either the decline or the failure to recover of the Steller sea lion population.

  • Sea of Okhotsk: Seals, Seabirds and a Legacy of Sorrow
    SEA OF OKHOTSK: SEALS, SEABIRDS AND A LEGACY OF SORROW Little known outside of Russia and seldom visited by westerners, Russia's Sea of Okhotsk dominates the Northwest Pacific. Bounded to the north and west by the Russian continent and the Kamchatka Peninsula to the east, with the Kuril Islands and Sakhalin Island guarding the southern border, it is almost landlocked. Its coasts were once home to a number of groups of indigenous people: the Nivkhi, Oroki, Even and Itelmen. Their name for this sea simply translates as something like the ‘Sea of Hunters' or ‘Hunters Sea', perhaps a clue to the abundance of wildlife found here. In 1725, and again in 1733, the Russian explorer Vitus Bering launched two expeditions from the town of Okhotsk on the western shores of this sea in order to explore the eastern coasts of the Russian Empire. For a long time this town was the gateway to Kamchatka and beyond. The modern make it an inhospitable place. However the lure of a rich fishery town of Okhotsk is built near the site of the old town, and little and, more recently, oil and gas discoveries means this sea is has changed over the centuries. Inhabitants now have an air still being exploited, so nothing has changed. In 1854, no fewer service, but their lives are still dominated by the sea. Perhaps than 160 American and British whaling ships were there hunting no other sea in the world has witnessed as much human whales. Despite this seemingly relentless exploitation the suffering and misery as the Sea of Okhotsk.

  • Status and Occurrence of Parakeet Auklet (Aethia Psittacula) in British Columbia
    Status and Occurrence of Parakeet Auklet (Aethia psittacula) in British Columbia. By Rick Toochin and Louis Haviland. Introduction and Distribution The Parakeet Auklet (Aethia psittacula) is a small species of auklet found breeding in the Beringia region of Alaska and Russia (Gaston and Jones 1998). This species has an Alaskan population estimated at 1 million birds (Gaston and Jones 1998). There is also a Russian population, but the exact population total is not known, due to a lack of population inventory work, but it is estimated to number about 400,000 birds with the vast majority, about 300,000 birds, found in the Sea of Okhotsk (Gaston and Jones 1998). The Parakeet Auklet has breeding colonies that are found on rocky mainland points and islands in the Gulf of Alaska (Jones et al. 2001). These sites include: Shumagin Island, Semidi Isand, Chirikof Island near Kodiak, locally in Kenai Peninsula and southeastern Alaska with small numbers south to St. Lazaria, Hazy and Forrester Island; and in the Aleutian Islands west to Buldir and Agattu Island; and in the Bering Sea at Little Diomede, St. Lawrence Island, King Island, St. Matthew Island, Pribilof Island and Nunivak Island (Sowls et al. 1978). The Parakeet Auklet also breeds in Russia in the Kurile Island chain with colonies on Chirinkontan, Lovushki, Raikoke, Matua, Yankicha, Simushir, Brat Chirpoev, Urup, and Iturup Island (Jones et al. 2001, Brazil 2009). They are also breeding on islands in the Sea of Okhotsk with colonies on Sakhalin, Tyuleniy, Iona, Talan, and Yamskyie Island (Jones et al. 2001, Brazil 2009). The Parakeet Auklet is also found breeding on Commander Island, and northwards locally along coast of the Kamchatka Peninsula, on Karaginski Island, Cape Navarin, and on Chukotka Peninsula (Konyukhov 1989, Kondratyev et al.

  • Phylogeography of Steller Sea Lions: Relationships Among Climate Change, Effective Population Size, and Genetic Diversity
    Journal of Mammalogy, 92(5):1091–1104, 2011 Phylogeography of Steller sea lions: relationships among climate change, effective population size, and genetic diversity C. D. PHILLIPS,* T. S. GELATT,J.C.PATTON, AND J. W. BICKHAM Center for the Environment, Purdue University, West Lafayette, IN 47907, USA (CDP, JCP, JWB) Department of Forestry and Natural Resources, Purdue University, West Lafayette, IN 47907, USA (CDP, JCP, JWB) National Marine Fisheries Service, Alaska Fisheries Science Center, National Marine Mammal Laboratory, 7600 Sand Point Way, NE, Seattle, WA 98114, USA (TSG) * Correspondent: [email protected] The biology of the Steller sea lion (Eumetopias jubatus) has been the subject of intense scientific investigation. This is primarily due to the rapid decline of population size in the western part of the species’ range since the 1970s and the subsequent Threatened and Endangered species listings that had direct impact on the management of one of the world’s largest fisheries. The Steller sea lion has emerged as an indicator species representing the environmental health of the North Pacific Ocean and Bering Sea. In this study, to better understand the historical processes that have culminated in the extant populations of E. jubatus, a large genetic data set consisting of 3 mitochondrial regions for .1,000 individuals was analyzed from multiple phylogeographic and demographic perspectives. The results describe the role of climate change in shaping the population structure of E. jubatus. Climatically associated historical processes apparently involved differential demographic responses to ice ages (and putative glacial vicariance) dependent on population size. Ice ages during times of small effective population size promoted restricted gene flow and fragmentation, and ice ages occurring during times of large population size promoted gene flow and dispersal.

Degterev Yuzhno-Sakhalinsk, Russia *E-mail: [email protected] Abstract Резюме RUS The report based on the analysis of satellite images considers the features of the changes in the configuration of the coastline of Raikoke island volcano (Middle Kuril Islands) caused by a strong explosive eruption on June 21–25, 2019. As a result of the accumulation of a significant amount of material from pyroclastic flows and tephra along the periphery of the volcanic edifice ejected during the active phase of the eruption, the area of Raikoke Island has sharply increased by 0.53 km2 (12.7 % of the original area). Immediately after the end of the eruption, under the influence of wave processes and alongshore currents, the destruction process of newly formed land areas has begun. Such cyclic processes are shown to be typical for the volcanic islands of the region and determine the coastline development and the appearance of the coastal zone as a whole.

Ohio Simulated Emergency Test “Black Swan 2018” (from Stan, N8BHL – Section Emergency Coordinator) ARES / W8SGT report - October 6-7, 2018 Executive Summary Ohio Auxcomm participated in the ARES “Simulated Emergency Test (SET)” creating a multi-state severe weather event in which many Ohio county ARES organizations tested their ability to activate, react to a winter storm with damage to communication infrastructure and other localized situations created by the county ARES Emergency Coordinator (EC). As the centerpiece of amateur radio assistance to Ohio, the Auxcomm station at Ohio EOC/JDF, W8SGT, was operational from 8 AM – 6 PM Saturday and 8 AM – 2 PM Sunday. W8SGT communicated with over 50 individual stations in at least 27 counties during the period, distributing 25 operational bulletins (OPBUL) throughout the period and handing a large amount of message traffic. The station was fully operational using HF 3.902 MHz sideband voice, HF 3.585 MHz digital messaging, VHF FM voice message handling, and UHF DMR digital voice checkins ( 16 stations in 9 counties). This was an excellent test requiring us to run full resources at the station and produced some quantifiable results. Overall, operationally the station handled the winter blizzard very well. The station was able to connect to SHARES/FEMA stations on 60 meters, an important interoperability test. There are some technical issues which were known prior but which showed up as significant restrictions to the stations operations. These primarily center on antenna problems which should be addressed.
