Sažetak
Today we face an increased need to solve complex ecological challenges, such as synergistic effects of biological invasions and climate change. Thus, assessing effectiveness of invasive species management scenarios or conservation priorities for endangered native populations affected jointly by biological invasions and climate change, is crucial. While field and laboratory studies required for such assessments are costly and logistically challenging, mathematical modelling offers a good alternative. Bioenergetic mechanistic modelling, in particular, can integrate all relevant species-specific biological and ecological information, and can be applied to identify high-risk species in a changing environment and/or management scenario with the highest impact on invasive crayfish abundances. Here we demonstrate the application of Dynamic Energy Budget (DEB) models in: i) development of a conceptual population dynamics model for evaluation of effectiveness of different approaches to signal crayfish control and ii) comparison and assessment of individual growth and reproduction of two prominent crayfish invaders (signal crayfish and the marbled crayfish) and two native and endangered crayfish (noble crayfish and stone crayfish) under changing environmental conditions. Since DEB models capture dependence of metabolism, and therefore ontogeny, on environmental and population conditions, they can be used to investigate diverse biological and ecological questions. Based on the examples of the two studies presented here, we argue that mechanistic models in general, and bioenergetics models in particular, should be at the core of adaptive management and decision-making in nature conservation and ecosystem restoration.
