Though declines in the growth and condition of Great Lakes lake whitefish ( Coregonus clupeaformis ) have been largely attributed to food web disruptions caused by invasive dreissenid mussels, a comprehensive evaluation of alternative hypotheses is currently lacking. Using various statistical approaches, we evaluated 69 years of data from the inner basin of South Bay, Lake Huron, considering the role of biological variables (food availability as Diporeia abundance and lake whitefish relative abundance as catch per unit effort, CPUE) versus environmental variables (climate change as growing degree days >5 °C and productive habitat capacity as percent epilimnetic volume, EV) on the condition and early growth rates of resident lake whitefish. Consistently, biological variables (Diporeia abundance, CPUE) best explained changes in lake whitefish growth and condition, respectively, in years when Diporeia data were available. In their absence, environmental variables (EV) best explained early growth rates of lake whitefish, whereas CPUE again best explained lake whitefish condition. Our analysis revealed that environmental change contributed significantly but alone was not sufficient to explain declines in lake whitefish growth after dreissenid establishment, whereas biological variables considered here could account for the majority of growth and condition changes observed in this population.

Some information on the size and density of voids that develop in several high purity metals and alloys during irradiation with neutrons at elevated temperatures has been reported as a function of irradiation parameters. An area of particular interest is the nucleation and early growth stage of voids. It is the purpose of this paper to describe the microstructure in high purity nickel after irradiation to a very low but constant neutron exposure at three different temperatures.Annealed specimens of 99-997% pure nickel in the form of foils 75μ thick were irradiated in a capsule to a total fluence of 2.2 × 1019 n/cm2 (E > 1.0 MeV). The capsule consisted of three temperature zones maintained by heaters and monitored by thermocouples at 350, 400, and 450°C, respectively. The temperature was automatically dropped to 60°C while the reactor was down.

In line with the times demand, nationlism changes as a dynamic of dialectics proceeds with changes in social, political, and ekonomic in the country and global levels. Based on a review of historical chronology, this paper analyzed descriptively the relationship between Islam and nationalism in Indonesia. Since the early growth of nationalism and the Dutch colonization period in Indonesia, Islam became the spirit of sacrifice of lives and property of the Indonesian people's fighting to get independence and on the Japanese colonial period and the early days of independence, Islam through the muslim leaders founction as base of departure and developer awareness of nasionalism, patriotism and unity to defend the independence. Despite the authoritarian New Order ruler cope with Islam through the establishment of the Association of Indonesian Muslim Intellectuals (ICMI), but awareness of national Muslim leaders to build Indonesia managed to push governance reforms. And in this era of reform, the spirit of nationalism and the spirit of sacrifice of the Indonesian leaders increasingly eroded by corruption. Key words: proto-nationalism, political nationalism, cultural nationalism.

ABSTRACTThe geographic position, astronomic factors (e.g. the Earth’s maximum distance from the Sun during winter), ice cover and altitude are the main factors affecting the climate of the Antarctic, which is the coldest place on Earth. Parts of Antarctica are facing the most rapid rates of anthropogenic climate change currently seen on the planet. Climate changes are occurring throughout Antarctica, affecting three major groups of environmental variables of considerable biological significance: temperature, water, UV-B radiation.Low diversity ecosystems are expected to be more vulnerable to global changes than high diversity ecosystems
