When the ancient supercontinent of Gondwana disintegrated and the fragments drifted apart to form continents, Antarctica became very isolated over the geographic south pole. From its former near-subtropical forests, Antarctica has become the coldest, windiest, driest and highest continent that is almost entirely covered with ice sheets several kilometres thick. The Circumpolar Current that developed in ARNTZ, G.A. LOVRICH and S. THATJE (eds.) Changing chain: past, present and future of the Scotia Arc's and Antarctica's shallow benthic communities* DAVID K.A. BARNES British Antarctic Survey, N.E.R.C., High Cross, Madingley Road, Cambridge, CB3 OET, England. E-mail: dkab@bas.ac.uk SUMMARY: The Scotia Arc links Patagonia to the Antarctic Peninsula. This island chain has changed considerably since Antarctica's geographic and thermal isolation from other land and water masses. Now its rates of air, land and fresh-water climate change are among the highest measured. This review examines work on the shallow water benthos of this region in the context of climate change. In summer, primary productivity is as intense as anywhere, whilst in winter the water reaches unprecedented clarity. Suspension feeders may eat for just a few months but others feed all year. Growth and reproduction are up to 50x slower than non-polar rates. Life here is in the slow lane. There is intense summer disturbance from icescour and wave action. This has erased shore zonation and created it below the surface. In contrast to summer disturbance, the winter is among the calmest and most thermally stable environments, when the area is overlain by fast ice. Whilst few animal phyla or species are represented on land, phyletic richness-and in some groups species richness-rivals that of tropical regions. Data showing clines in benthic richness at several taxonomic levels across the Patagonia-South Georgia-Signy Is.-Adelaide Is. chain and 50 years of ice-sheet retreat are presented.Keywords: polar benthos, zonation, metabolism, suspension-feeding, growth, reproduction. RESUMEN: UNA CADENA CAMBIANTE: PASADO, PRESENTE Y FUTURO DE LAS COMUNIDADES BENTÓNICAS SOMERAS DEL ARCODE SCOTIA Y ANTÁRTIDA. -El Arco de Scotia conecta la Patagonia con la Península Antártica. Esta cadena de islas ha cambiado considerablemente desde el aislamiento geográfico y térmico de la Antártida respecto de otras masas de agua y tierra. Actualmente, esta área tiene las tasas de cambios climáticos más elevadas, tanto en aire, tierra y aguas continentales. En esta revisión, se examinan los estudios en las comunidades bentónicas de aguas someras en el contexto del cambio global. La productividad primaria es, durante el verano, tan intensa como en otras áreas, mientras que en invierno las aguas alcanzan una claridad sin precedentes. Los suspensívoros pueden alimentarse por apenas unos pocos meses, pero otros se alimentan durante todo el año. El crecimiento y la reproducción son hasta 50 veces más lentos que en los organismos no polares. La vida aquí está en el "carril lento". Durante...

Population dynamics of the queen scallop, Aequipecten opercularis, was investigated in the western English Channel off Roscoff. Annual formation of natural growth rings on the shell surface was validated by stable isotope (y 18 O and y 13 C) analysis. A von Bertalanffy growth function (H t = 58.9 mm . (1Àe À 0.604.(t + 0.235) )) was fitted to size-at-age data of 249 individuals. Annual somatic and gonad production amounted to 19.74 kJ m À 2 and 0.98 kJ m À 2 y À 1 , respectively. Total mortality rate Z was estimated to be 1.716 y À 1 . Net growth efficiencies (ranging from 45% in 1-y-old to 11% in 6-y-old individuals) were in the same range as in other short-lived scallops. Individual growth, however, was distinctly slower in this population than in other A. opercularis populations from similar latitudes, most likely due to a more stressful environment. D

Antarctic echinoderms appear to be adapted to a benthic environment characterized by long-term low availability of food resources. As predicted for a low-energy system, most echinoderms appear to expend little energy on feeding. Moreover, they are primarily generalists which opportunistically &splay scavenging or necrophagous feeding habits. Others exploit detrital material, or ingest microorganisms from the benthos and plankton. Those echinoderms which are feeding specialists exploit prey which are low in energy content yet extremely abundant, such as sponges. Even though in&viduals may have a low energy intake, it is likely that echinoderms play a significant role in energy transfer in antarctic benthos, as they are among the most abundant of epibenthic macroinvertebrate groups in shallow antarctic seas.
