Assessing the sensitivity of bivalve populations to global warming using an individual-based modelling approach ArchiMer
Thomas, Yoann; Bacher, Cedric.
Climate change exposes benthic species populations in coastal ecosystems to a combination of different stressors (e.g. warming, acidification and eutrophication), threatening the sustainability of the ecological functions they provide. Thermal stress appears to be one of the strongest drivers impacting marine ecosystems, acting across a wide range of scales, from individual metabolic performances to geographic distribution of populations. Accounting for and integrating the response of species functional traits to thermal stress is therefore a necessary step in predicting how populations will respond to the warming expected in coming decades. Here, we developed an individual‐based population model using a mechanistic formulation of metabolic processes...

Effect of environmental factors on the abundance of decapod crustaceans from soft bottoms off southeastern Brazil Anais da ABC (AABC)
FURLAN,MICHELE; CASTILHO,ANTONIO L.; FERNANDES-GÓES,LISSANDRA C.; FRANSOZO,VIVIAN; BERTINI,GIOVANA; COSTA,ROGéRIO C. DA.
This study investigated the importance of variations in environmental factors affecting the abundance patterns of decapods on the southeastern Brazilian coast. Sampling was carried out monthly from January 1998 through December 1999 in Ubatumirim and Mar Virado, Ubatuba region, using a commercial shrimp fishing boat equipped with double-rig nets. Six areas adjacent to rocky shores were chosen. Bottom-water samples were collected using a Nansen bottle, to measure the temperature and salinity. Sediment samples were also obtained by means of a Van Veen grab, for determination of texture and organic-matter content. The association of environmental factors with species abundance was evaluated by Canonical Correspondence Analysis (α = 0.05). Forty-one species of...
