Planktonic foraminiferal biomineralization intensity, reflected by the weight of their shell calcite mass, affects global carbonate deposition and is known to follow climatic cycles by being increased during glacial stages and decreased during interglacial stages. [...]

9 p, 145.6 KB Herbivory and plant growth rate determine the success of El Niño Southern Oscillation-driven tree establishment in semiarid South America / Holmgren, Milena (Wageningen University. Resource Ecology Group) ; Claramunt López, Bernat (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Squeo, Francisco A. (Universidad de La Serena - Centro de Estudios Avanzados en Zonas Aridas - Instituto de Ecología y Biodiversidad)
While climatic extremes are predicted to increase with global warming, we know little about the effect of climatic variability on biome distribution. Here, we show that rainy El Niño Southern Oscillation (ENSO) events can enhance tree recruitment in the arid and semiarid ecosystems of north-central Chile and northwest Peru. [...]

14 p, 334.1 KB Métodos de reducción de escala : aplicaciones al tiempo, clima, variabilidad climática y cambio climático / Amador, Jorge A. (Universidad de Costa Rica. Centro de Investigaciones Geofísicas) ; Alfaro, Eric J. (Universidad de Costa Rica. Centro de Investigaciones Geofísicas)
Los Modelos de Circulación General Atmosféricos-Oceánicos Acoplados muestran buena habilidad para simular la evolución de las circulaciones de escala global. Sin embargo, esta bondad no es muy útil para el estudio de impactos locales debido a que la resolución espacial de esos modelos está por encima de la escala de los impactos locales que se desean analizar. [...]
Coupled Atmosphere-Ocean General Circulation Models demonstrate good skill in simulating large scale circulations. However this output is not very useful to study local impacts, as its spatial resolution is courser than the scale of local impacts. [...]

Institut de Ciència i Tecnologia Ambientals) ; Diz, Paula (Cardiff University. School of Earth, Ocean, and Planetary Sciences)
Sortable silt mean grain sizes together with oxygen and carbon isotopic data produced on the benthic foraminiferal species Fontbotia wuellerstorfi are used to construct high-resolution records of near-bottom flow vigour and deep water ventilation at a core site MD02-2589 located at 2660 m water depth on the southern Agulhas Plateau.

14 p, 875.1 KB Centennial-scale variability of the British ice sheet: implications for climate forcing and Atlantic meridional overturning circulation during the last deglaciation / Knutz, Paul C. (University of Copenhagen. Geological Institute) ; Zahn, Rainer (Universitat Autònoma de Barcelona. Institut de Ciència i Tecnologia Ambientals) ; Hall, Ian R. (Cardiff University. School of Earth and Ocean Sciences)
Evidence from paleoclimatic archives suggests that Earth's climate experienced rapid temperature changes associated with pronounced interhemispheric asymmetry during the last glacial period. Explanations for these climate excursions have converged on nonlinear interactions between ice sheets and the ocean's thermohaline circulation, but the driving mechanism remains to be identified. [...]

Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Erba, Elisabetta (University of Milan. Department of Earth Sciences ''Ardito Desio'') ; Thunell, Robert C. (University of South Carolina. Department of Geological Sciences)
A high-resolution study of calcareous phytoplankton in a box core from the Santa Barbara Basin (SBB) reveals floral assemblage fluctuations which can be related to climatic and paleoceanographic changes during the last half century (1940-1996). [...]
