Virtual Issue: Nutritional Ecology: January 2009

Edited by Carol L. Boggs & David Raubenheimer
January 2009

Research on nutritional ecology is extensive, yet the area is under-recognized as a distinct field (Raubenheimer & Boggs, 2009). This virtual issue of Functional Ecology highlights a selection of the articles appearing in the journal over the past two years that focus on nutritional ecology. Many of these articles address questions within the broad areas covered by the accompanying special issue on nutritional ecology (Caut et al., 2008; Lee et al., 2008; Tibbets et al., 2008; Hessen et al., 2007; Krockenberger & Hume, 2007). Others further expand the organismal focus to include work on plants (Butler & Ellison, 2007), phytoplankton (Danger et al., 2007), marine invertebrates (Byrne et al., 2008), and birds (Catoni et al., 2008; Schaefer et al., 2008; Tschirren et al., 2007). We expand the conceptual focus to studies of metabolic processes (Voigt & Speakman, 2007) and of phenotypic plasticity, including plastic reproductive responses (Banet & Reznick, 2008; Byrne et al., 2008).

We hope that this virtual issue will give the reader a picture of the pervasive importance of nutritional ecology within functional studies. Acquisition, processing and allocation of resources constitute an underlying mechanism for many ecological and evolutionary processes. A synthetic understanding of ecology and evolution must be built on this foundation.
