Reconstruction of food conditions for Northeast Atlantic bivalve species based on Dynamic Energy Budgets

Modelling shellfish growth with dynamic energy budget models: an application for cockles and mussels in the Oosterschelde (southwest Netherlands)

“…More recently, another approach has been used involving a dynamic reconstruction of the scaled functional response using reverse modelling for various bivalve populations across the NE Atlantic coast (Freitas et al 2009). Results from that study showed that, across systems, C. edule experienced better food conditions when compared with other bivalve species, and that M. edulis presented the lowest food conditions in all the areas analysed.…”

Near-future ocean acidification impacts maintenance costs in sea-urchin larvae: Identification of stress factors and tipping points using a DEB modelling approach

“…Dynamic Energy Budget (DEB) models are particularly useful for such quantitative assessments. DEB theory is one of the most comprehensive framework for bioenergetics (Kooijman, 2001;Nisbet et al, 2000), and models based on this theory have been extensively applied to understand the effects of chemical stress (see Jager and Zimmer, 2012;Jager et al, 2006) and environmental factors such as food and temperature (e.g., Freitas et al, 2009), including the ecological consequences of climate change (e.g., Teal et al, 2012). Recently, Muller and Nisbet (2014) presented a DEB model for the effects of ocean acidification on calcifying phytoplankton (coccolithophores).…”

An Overview of Factors Affecting Distribution of the Atlantic Surfclam (Spisula solidissima), a Continental Shelf Biomass Dominant, During a Period of Climate Change

“…Like most bivalves, surfclam adult size is dependent on the relative rates of respiration and ingestion; both are temperature controlled. In bivalves, respiration typically scales as the cube of the length (Powell & Stanton 1985, Freitas et al 2009, Powell et al 2015b, whereas ingestion, which is a function of the two-dimensional surface of the gill, tends to scale as the square of the length (Powell et al 1992, Hofmann et al 2006, van der Meer 2006. This differential scaling produces physiological challenges for large-sized bivalves; at some point, ingestion is just able to meet respiratory demands and, perhaps, reproduction, and at that point, growth ceases.…”

“…This differential scaling produces physiological challenges for large-sized bivalves; at some point, ingestion is just able to meet respiratory demands and, perhaps, reproduction, and at that point, growth ceases. Temperature influences on respiration tend to follow a Q 10 relationship, with respiration increasing with rising temperature over the bivalveÕs physiological range (e.g., references in Powell & Stanton 1985, Freitas et al 2009). Ingestion, however, tends to follow a leftskewed parabolic relationship in which ingestion rate rises with increasing temperature up to an optimal level and then declines at a rapid rate as temperature continues to rise (e.g., Hofmann et al 2006, Flye-Sainte-Marie et al 2007, Munroe et al 2013b).…”
