This leads to "summer dormancy" in many benthic suspension feeders due to energetic constraints. Analysis of the most recent 33-year temperature time series demonstrated enhanced stratification due to global warming, which produced a ≈40% lengthening of summer conditions. Many biological processes are expected to be affected by this trend, culminating in such events as mass mortality of invertebrates. Climatic anomalies concomitant with the occurrence of these events represent prolonged exposure to warmer summer conditions coupled with reduced food resources. Simulation of the effects of these conditions on a model organism demonstrated a biomass loss of >35%. Losses of this magnitude result in mortality similar to that noted in field observations during mass mortality events. These results indicate that temperature anomalies are the underlying cause of the events, with energetic constraints serving as the main triggering mechanism Support for this work was provided by FPI fellowships from the Ministerio de Ciencia e Innovación (MCI) of Spain (to E.S. and E.J.) and by MCI Projects CTM 2006–01463 and CGL2007–66757-C02–01/BOS Peer reviewed 2009-07-27T08:02:28Z 2009-07-27T08:02:28Z 2009-03-30 artículo http://purl.org/coar/resource_type/c_6501 Proceedings of the National Academy of Sciences of the USA (PNAS) 106(15): 6176-6181 (2009) 0027-8424 http://hdl.handle.net/10261/15373 10.1073/pnas.0805801106 19332777 en https://doi.org/10.1073/pnas.0805801106 none 162733 bytes application/pdf National Academy of Sciences (U.S.) |
