Synopsis of research, including reference to publications and grants in above lists

My research interests and activities encompass the following major areas in mammalian research: 1) behaviour, 2) population ecology, 3) physiology and 4) parasitology.  I combine field and laboratory methods to investigate physiological, parasitological and ecological processes that determine life history strategies in mammals.

Animal behavior and population ecology. I started my scientific career in studies on the behavioural determinants of spatial distribution of small mammals. These studies had two main directions, namely (a) relationships between agonistic behaviour and reproductive patterns in house mice (Mus musculus) and (b) spatio-ethological variability in populations of house mice. The studies included ecological, genetic and behavioral aspects to reveal the influence of interactions among individuals on the spatial distribution and reproductive success within mice populations. I found that social interactions among individuals within groups are related to plasticity of their behavioural and physiological characteristics (such as aggressiveness, the speed of establishment of conditional reflexes, stress resistance) which, in turn, are determined genetically. The level of plasticity determines the reproductive success of group members (publ. C-2; D-1, 2).

The effect of environmental influence on the spatio-ethological structure in Mus musculus populations was examined both in the field and in the laboratory. Within populations, social relations, as well as spatial distribution of individuals, depend on habitat productivity, habitat complexity and climatic parameters.  Furthermore, each type of spatio-behavioral structure is related to specific environmental conditions (publ. C-1-4; D-2-3).

Research on comparative population ecology of gerbils was conducted in the Negev desert (publ. D-4-6, 9-10, 15, 19, 23, 27, 36). The rationale of this research was as follows: a species occurs in a particular habitat and is absent from another is that the species is adapted to the physical characteristics of its preferred habitat. These adaptations facilitate the performance of a species in its habitats so that it achieves the highest fitness. Consequently, the comparison of the performance of species in different habitat associations will help to answer the question of what determines habitat preference.

Physiological ecology. Nutritional factors play an important role in the evolution and population dynamics of animals. Nutritional ecology of desert rodents has been studied since 1993 (D-7, 11-13, 16, 20-21, 28, 30, 37, 42, 53, 71, 78, 97, 99, 102-103) using field and laboratory investigations of nutrition, energetics, growth, and reproductive biology of small mammals. Desert gerbilline rodents consume mainly plant material, in particular seeds. In the Negev Desert, typical of desert habitats, there is an abrupt emergence of green vegetation triggered by unpredictable precipitation. Thus, many rodents shift their diet from predominantly seeds to one containing more vegetation. I examined factors affecting the ability of different-sized desert rodents to utilize desert plants, and the impact of diet on maintenance, growth and reproduction. I also measured field (FMR) and average daily (ADMR) metabolic rates of desert rodents. Behavioral studies were conducted to determine diet selection and time-energy budgets of desert animals. Body size influences energy expenditure and dietary selection of animals in that small mammals require more energy and water per unit gut capacity than large mammals. I have shown that small gerbils consume a more energy-rich diet. Moreover, G. henleyi (10-12 g) are able to select energy-rich parts from low-digestible, energy-poor plants.

I have a particular interest in interactions of nutrition and reproduction in small mammals. I found that reproductive activities are sensitive to energy intake: with restricted energy intake, the estrous cycle and reproductive activities are disrupted but can be restored with provision of adequate energy. This strategy ensures that reproduction occurs when conditions of food availability and body condition of the females are favorable. Reproduction is one of the most costly activities in terms of energy expenditure and water requirements in females. In A. cahirinus, metabolizable energy intake was the main factor determining growth of young and the proportional increase in water input in lactating females was greater than the proportional increase in energy intake. Lactating M. crassus used a combination of reallocation of energy and increased metabolizable energy: females reduced energy expenditure for maintenance to compensate for increased energy requirements and used this saved energy, in addition to the increased metabolizable energy intake and mobilization of body energy reserves, for milk production. Reproductive parameters of females (such as milk production and growth rate of young) were positively correlated with ADMRs of females.

Ecological parasitology. Unlike endoparasites, ectoparasites are influenced not only by their host characteristics, but also by the off-host environment. Therefore, the habitat of the ectoparasite should be considered as not only a particular host, but also rather a particular host in a particular habitat. This raises the question of the role of the host-habitat relationship in determining ectoparasite community structure. The second important question in ecological parasitology is related to reciprocal physiological influences between the host and the parasite (publ. C-5; D-14, 17-18, 22, 24-26, 29-35, 38-41, 43-52, 54-70, 72-77, 79-95; 96, 98-101, 104-118, grants 2-11). These studies include the investigation of the effect of rodent physiological and reproductive status on foraging, reproductive success and performance of their flea parasites. In addition, I am studying the effect of ectoparasites on energy requirements of their rodent hosts and question whether the effect of flea parasitism is most critical during most energy-demanding periods of an individual life of rodent (breeding season, pregnancy, lactation). In addition, the study of the immunological parameters of flea-rodent relationships began recently to broaden the scope of the research of environment-host-parasite relations. In particular, I demonstrated that rodents develop cross-resistance against several closely related flea species. The pattern of mounting the immune response in a rodent species differs among species, and is related to the level of natural flea infestation and the diversity of flea assemblages. The resistance against fleas can be, albeit up to certain degree, transferred from mother to offspring. Current studies include the determination of causes of host-specificity of flea species to understand host-parasite co-evolution. Important is the effect of host grooming pattern, host blood composition and skin structure on the pattern of flea parasitism and the ability of the flea to identify the preferred host. Additional studies deal with macroecological and evolutionary patterns of mammal-flea relationships such as relationships between host specificity and size of geographic range and geographic variability of the diversity of flea assemblages within and among host species.
