Sažetak
In October 2019, conservation status of Mediterranean endemic bivalve Pinna nobilis was updated from endangered to critically endangered on the IUCN Red List of Threatened Species. Conservation measures focus on captive breeding, reintroduction, and preservation of still intact populations. All of these measures can benefit from understanding how environmental conditions affect organism's physiology. Mechanistic models in general, and bioenergetic models in particular, enable us to understand how the physiology of an organism responds to different environmental conditions. They are, therefore, an important tool for informed conservation planning and related decision-making. We present a mechanistic model of P. nobilis set within the Dynamic Energy Budget (DEB) framework. DEB theory is a mechanistic approach to capturing individual’s acquisition and utilization of available energy for growth, maturation, development, and reproduction, as a function of environmental conditions, over the entire life-cycle of an individual. We successfully parameterized the DEB model using available literature data for P. nobilis and the corresponding environmental temperature and food availability, and validated the model using independent data. We then used the model to quantify growth, maturation and reproduction for various environmental scenarios. The DEB model can be used as a standalone tool, or be implemented into population and/or ecosystem models, thus facilitating various conservation approaches ranging from species to ecosystems. Due to its (i) universal description of organism’s physiology, (ii) simplified parameterisation using available literature data, (iii) ability to assimilate data from disparate sources and scales of biological organization, and (iv) ability to predict effects of environmental scenarios for which data do not exist, the DEB modelling approach can be an attractive tool for informing conservation practice, applicable to any species of interest.
