Microbial communities of aquatic environments on Heard Island characterized by pyrotag sequencing and environmental data
Heard Island in the Southern Ocean is a biological hotspot that is suffering the effects of climate change. Significant glacier retreat has generated proglacial lagoons, some of which are open to the ocean. We used pyrotag sequencing of SSU rRNA genes and environmental data to characterize microorganisms from two pools adjacent to animal breeding areas, two glacial lagoons and Atlas Cove (marin...
متن کاملTerrestrial vegetation dynamics and global climate controls
Monthly data from the moderate resolution imaging spectroradiometer (MODIS) and its predecessor satellite sensors was used to reconstruct vegetation dynamics in response to climate patterns over the period 1983–2005. Results suggest that plant growth over extensive land areas of southern Africa and Central Asia were the most closely coupled of any major land area to El Niño–southern oscillation...
متن کاملThe Biogeography of Shallow-water Macrofauna Heard Island
Collections of23 macroinvertebrate taxa associated with Durvillaea antarctica hold fasts and 58 invertebrate taxa associated with artificial substrata coliectots are described flOm shallow-water and intertidd habitats at Heard Island. The fauna strong biogeographic affinities with the Kerguelen Island fauna and, to a slightly lesser extent, the fauna recorded at Macquarie Island but negligible ...
متن کاملMark and Baylis: Secretary Island Vegetation
The continuing effects of red deer on the rain forest of Fiordland's Secretary Island (80 km2) over the last six years are described in relation to their initial impact and control operations. On easily accessible sites the range of affected species is increasing as the most palatable become depleted while some previously unmodified sites are now threatened. Photographic records, quantitative s...
متن کاملManagement Considerations for the Heard Island Lava Tube Caves
Heard Island contains a system of lava tube caves in a largely pristine condition which are the best developed bedrock caves known in Antarctic or Subantarctic latitudes. They require special management, because of significant and sometimes fragile attributes associated with cave geomorphology, geology, hydrology, atmospheres, soils, microbiology, flora, fauna, vertebrate palaeontology, archaeo...
