摘要： "唉!……"贝壳大叔望着满桌子的抗议信发呆。这些信件全都是一个意思:鲸鱼老是在"海洋运动会"上得第一名,好像这个运动会是专门为鲸鱼准备的,其它任何一个海洋生物都不是"海洋巨人"——鲸鱼的对手。没有竞争的运动会没意思,海洋生物们强烈要求:本届"海洋运动会",鲸鱼要退出比赛。的确,海洋里每次运动会冠军都是鲸鱼家族。记得去年是长须鲸,前年是虎鲸,大

摘要： Increasing atmospheric CO2 concentrations are causing decreased pH over vast expanses of the ocean. This decreasing pH may alter bio-geochemical cycling of carbon and nitrogen via the microbial process of nitrification, a key process that couples these cycles in the ocean, but which is often sensitive to acidic conditions. Recent reports have indicated a decrease in oceanic nitrification rates under experimentally lowered pH. How the composition and abundance of ammonia-oxidizing bacteria (AOB) and archaea (AOA) assemblages respond to decreasing oceanic pH is unknown. We sampled microbes from 2 different acidification experiments and used a combination of qPCR and functional gene microarrays for the ammonia monooxygenase gene (amoA) to assess how acidification alters the structure of ammonia oxidizer assemblages. We show that despite widely different experimental conditions, acidification consistently altered the community composition of AOB by increasing the relative abundance of taxa related to the Nitrosomonas ureae clade. In one experiment, this increase was sufficient to cause an increase in the overall abundance of AOB. There were no systematic shifts in the community structure or abundance of AOA in either experiment. These different responses to acidification underscore the important role of microbial community structure in the resiliency of marine ecosystems.

摘要： Systematic conservation planning for developing marine spatial protection includes analysis of the spatial distribution of fishing activities, existing management and ecological characteristics. This paper assesses the overlap between habitat (bioregion), existing spatial management and Antarctic krill catch in the Southern Ocean. The analysis required standardised information on the location and extent of spatial fisheries management measures, which was delivered through a Geographic Information System (GIS). During the 2010/11 season, 64% of the CAMLR Convention Area was open to fishing for at least one species. There were important differences between pelagic bioregions in terms of the fraction that was open to fishing, and the distribution of catch within the open fraction. For example, only 26% of the main area open to krill fishing has been fished, and this fishing is concentrated in three of the seven bioregions found in the open area. Information on the distribution of catches and catch limits among different bioregions could be used to prioritise protection for bioregions that are currently under-represented in marine protected areas (MPAs). However, conservation planning should take account of uncertainties that result from the different spatial resolution of datasets and the use of long-term averages to identify spatial boundaries.

摘要： Decadal-to-century scale trends for a range of marine environmental variables in the upper mesopelagic layer (UML, 100-600 m) are investigated using results from seven Earth System Models forced by a high greenhouse gas emission scenario. The models as a class represent the observation-based distribution of oxygen (O-2) and carbon dioxide (CO2), albeit major mismatches between observation-based and simulated values remain for individual models. By year 2100 all models project an increase in SST between 2 degrees C and 3 degrees C, and a decrease in the pH and in the saturation state of water with respect to calcium carbonate minerals in the UML. A decrease in the total ocean inventory of dissolved oxygen by 2% to 4% is projected by the range of models. Projected O-2 changes in the UML show a complex pattern with both increasing and decreasing trends reflecting the subtle balance of different competing factors such as circulation, production, remineralization, and temperature changes. Projected changes in the total volume of hypoxic and suboxic waters remain relatively small in all models. A widespread increase of CO2 in the UML is projected. The median of the CO2 distribution between 100 and 600m shifts from 0.1-0.2 mol m(-3) in year 1990 to 0.2-0.4 mol m(-3) in year 2100, primarily as a result of the invasion of anthropogenic carbon from the atmosphere. The co-occurrence of changes in a range of environmental variables indicates the need to further investigate their synergistic impacts on marine ecosystems and Earth System feedbacks.
