“…These are in conformity with the observations of some previous workers. Studies of Badcock (1949), Brown (1961) and Baekken (1981) on Baetis rhodani and of Gupta and Michael (1981) on Baetis sp. in Shillong, Meghalaya revealed them to be mainly detritivorous whereas Brown (1960) has shown that several species of algae were thoroughly and rapidly digested by Cloeon dipterum in the laboratory.…”

“…Notable publications in this direction include those of Johansson (1958), Slansky (l980a, b), Ananthakrishnan et al (1982) and Raman and Sanjayan (1983). Whereas there are some investigations on feeding propensities (Brown 1960(Brown , 1961Gupta and Michael 1981;Venkataraman 1984), food habits (Baekken 1981), trophic relations (Winterbourn 1974), food preference and dependence of growth on the type of food (Cianciara 1980) and nutritional dynamics (Zimmerman and Wissing 1980), work on the impact of nutrition on reproduction of mayflies is conspicuous by its absence. The present investigation aims at understanding and comparing the feeding propensities, growth rate and fecundity of two species of Baetis and one species of Cloeon available in and around Madurai, based on laboratory observations.…”

The relative importance of organic detritus and algae in promoting the growth and fecundity of some species of Baetidae is assessed on the basis of the nutritional differences among them. Taking into consideration the ephemeral aspect of adult life, an understanding of the relative importance of such substances as carbohydrate, protein and lipid in relation to their growth and fecundity is also examined.

second editionDynamic Energy Budget theory unifies the commonalities between organisms as prescribed by the implications of energetics, which link different levels of biological organization (cells, organisms and populations). The theory presents simple mechanistic rules that describe the uptake and use of energy and nutrients and the consequences for physiological organization throughout an organism's life cycle, including the relationships between energetics and aging and the effects of toxicants. In this new edition, the theory is broadened to encompass the fluxes of both energy and mass. All living organisms are now covered in a single quantitative framework, the predictions of which are tested against a wide variety of experimental results at the various levels of biological organization. The theory explains many general observations, such as the body size scaling relationships of certain physiological traits, and provides a theoretical basis for the widely used method of indirect calorimetry. In each case, the theory is developed in elementary mathematical terms, but a more detailed discussion of the methodological aspects of mathematical modelling is also included, making the book suitable for biologists and mathematicians with a broad interest in both fundamental and applied quantitative problems in biology.Bas Kooijman is Professor of Applied Theoretical Biology at the Vrije Universiteit in Amsterdam and is also head of the University's Department of Theoretical Biology. His research focuses on mathematical biology, in particular ecotoxicology which provided the framework for the original version of his Dynamic Energy Budget theory published in 1993 (Dynamic Energy Budgets in Biological Systems -Theory and Applications in Ecotoxicology). From the first edition:"This book is an excellent scientific product that informs and forces contemplation of issues relating to population and community ecology. The author has made a complex subject coherent." Thomas G. Hallam, Bulletin of Mathematical Biology "... a very useful and general tool to select more ecologically sound process equations and parameters in ecological models." Sven Erik Jørgensen, Ecological Modelling "The author has made a significant contribution to the problem of modelling the dynamics of biological populations at the level of the individual by synthesizing this very complicated subject into a relatively short list of general assumptions and putting the energetics of sub-models for vital rates on a solid basis." Jim Cushing, Mathematical Biosciences "The family of idealized models offered in this book is capable of playing a role analogous to that of Lotka-Volterra models in population dynamics ... I am confident that any model(s) capable of occupying this niche will be strongly influenced by the ideas in this book."

“…The pointed shifts in diet composition among size classes could result in considerable changes in microhabitats, enabling a different habitat choice among the different size classes of both species, as noted by BAEKKEN (1981) for other mayflies. BAEKKEN (1981) thought this could reduce the interaction between nymphal stages within the same species and between two coexisting detritivores species, as seems to be the case in our study. This explanation could be also applied for interpreting the existence of a great range in nymphal size (ARNEKLEIV, 1996), as we found in our study.…”

We study the life history, nymphal feeding and secondary production of two leptophlebiid mayfly species (Habrophlebia eldae and Paraleptophlebia submarginata). They cohabit in a Mediterranean stream and present a very high niche overlap in terms of trophic resources. The life cycle was estimated using size-frequency analysis of samples taken throughout a year. Both species have a similar but displaced period of the nymphal development. Secondary production was calculated by means of the size-frequency method. Annual secondary production of P. submarginata is much higher than that of H. eldae (1.95 g DW m -2 year -1 vs. 0.17 g DW m -2 year -1), and presents a quite similar annual P/B ratio, but slightly higher in P. submarginata (6.97 in P. submarginata and 9.21 in H. eldae). The study of the gut contents revealed that they are mainly detritivores but, when larger they feed also on CPOM from leaves fallen in the stream. They present an almost total niche overlap in terms of food acquisition. However the previously mentioned shift in trophic resources utilization with size makes it possible that, because no similar size classes of each species are present at the same time, niche segregation exists between the two species. Though further studies are needed to confirm it, this could be the consequence of previous episodes of competition between them.
