Main research areas:
The main fields of my research interests cover ecological energetics, physiology biochemistry and genetics of marine invertebrates and their populations in geographical (macro) and habitat (micro) scales. The overarching theme of my research is understanding of the mechanisms limiting species distribution, determining maximal lifespan and allowing animal populations to withstand environmental stress A special focus was given to growth, reproduction and energy flows in natural and cultured populations of bivalve mollusks. My research topics and achievements can be divided in three following parts:
1. Energetics and production in bivalve populations. This topic was a part of a program on creation of the scientific background and rationale for Mytilus aquaculture in the White Sea (1984-1991). Specific goals: (a) to study seasonal variations of growth, metabolic and feeding rates in mussels in suspended culture conditions; comparison with natural populations; (b) to determine population structure, dynamics, recruitment, mortality and energy flows in cultured mussels; (c) to evaluate the impact of developing mussel culture on the environment, to elaborate simple and practical tools for the estimation of optimal loads of mussel cultures on coastal ecosystems in the White Sea. Output: This research formed a theoretical basis and provided multiple practical applications in a newly establishing branch of fisheries in the region – mussel aquaculture. The data are summarised in my PhD thesis (1990), the book on mussel aquaculture in the White Sea (1993), papers in peer reviewed journals (e.g. Kulakowski et al., 1986; Kulakowski, Sukhotin, 1986; Sukhotin, 1988; Sukhotin, Kulakowski, 1992; Sukhotin, 1992; Maximovich et al., 1996; Primakov et al., 2008). I use specific methods of ecological energetics also in other than aquaculture studies. We studied the effect of parasites on the metabolic rate in periwinkles (Lysen et al., 1992). In 1999-2004 I supervised a Ph.D. thesis of D.M. Martynova (defended in November 2004) on feeding of boreal plankton crustaceans and their role in the White Sea pelagic ecosystems.
2. Population biology of mussels. Since 1991 I study population biology and genetics in natural mussel populations in geographical scale (White Sea, Baltic Sea, Barents Sea, North Sea, Sea of Okhotsk) and in local scale (in different habitats) aiming to find out whole-animal and population mechanisms of maintaining of genetic composition in mussel populations and the factors limiting Mytilus populations’ persistence at the edge of the area of distribution. Output: an original classification system of phenetic characters (shell and foot colour polymorphism) and their genetic interpretation has been developed (Sergievsky, Sukhotin, 1993). It has been used in analysis of Mytilus population systems in both wide geographical scale (foot colour polymorphism) (Strelkov et al., 1995) and inter-habitat variation (shell colour morphs) (Sukhotin, Sergievsky, 1995). It has been shown that growth performance and stress sensitivity in bivalves are mostly determined by local habitat variation than by climatic factors (Sukhotin, Maximovich, 1994; Regoli et al., 1998; Amiard-Triquet et al., 1998; Bufalova et al., 2005; Sukhotin et al., 2007). Reduced abilities of metabolic depression during environmental anaerobiosis (reflected by enhanced ATP turnover rate) have been found to cause different abilities to withstand air exposure in mussels from intertidal habitats compared to cultured ones (Sukhotin, Portner, 1999). We have also found that molluscs from the Arctic populations have higher metabolic rate than their boreal conspecifics (Sukhotin et al., 2006), which suggests the possibility of metabolic compensation in eurythermal species. Currently I study the population structure (Sukhotin et al., 2008), growth, sexual cycle and seasonal changes in biochemical composition (lipids, proteins and glycogen content) of mussels Mytilus as potential food objects of marine waterfowl birds.
3. Biochemical and physiological mechanisms of ageing in animals with infinite growth. Since 1996 my research interests also encompass the study of molecular and physiological mechanisms of ageing in infinitely growing animals (most of aquatic invertebrates and vertebrate ectotherms), and its relation to population survival and dynamics. The existing ageing models and theories were elaborated mainly for homeotherms, insects and nematodes. However, the applicability of these theories to continuously growing species is unclear since most physiological rates are size-dependent and age differences are therefore masked by allometric effects. The problem have been discussed (e.g. Medvedev, 1990) of whether the infinitely growing species do have ageing at all, because most tissues of these animals are continuously proliferating and reproduction is not ceased until death. Size effects are especially important taking into account the interpopulational differences in growth and mortality rates in invertebrate species due to environmental differences over wide (geographical) or narrow (habitat) scales. Output: I have developed a new methodological approach to separate the effects of ageing and growth in infinitely growing species. On the model species (bivalve Mytilus edulis) it has been shown that metabolic rate as well as feeding rate depends on both size and age and decrease in aged specimens (Sukhotin et al., 2003; 2006). Metabolic reduction is accompanied by rapid decrease of growth rate and net growth efficiency, lowering of ATP and phosphagens levels in tissues, decline of some metabolic enzymes (citrate synthase) activity, intracellular pH and expressions of chaperones as well as an exponential increase in oxidative damage and accumulation of lipid peroxidation products (Sukhotin, Portner, 2001; Sukhotin et al., 2002; Ivanina et al., 2008). Currently I study age-related changes in cellular metabolism in bivalve molluscs.
