Michael Haslam,Tiago Falótico,Lydia Lunczes also diversify. Lake fish often specialize for use of either plankton or benthic prey, and it sometimes results in formation of species pairs or trophic polymorphism. Loss of parasitism is a special feature of lamprey radiation, and diversification of bony armor phenotypes is peculiar to stickleb

Habitat partitioning by zooplankton and the structure of lake ecosystemsractions. Using a standard . clone bioassay of food quality, we present evidence that these deviations can be accounted for by variable responses of algal communities that can alter their edibility of .

New Zealand mountain stream communities: Stable yet disturbed?es (logging and the development of land for forestry) and the temporal stability of stream faunas following afforestation with exotic conifers. These and other studies indicate that the faunas of many South Island mountain streams are dominated by the same widely distributed species characterized by

Rotifer life history strategies and evolution in freshwater plankton communitiesations are lowered by the clearance activity of cladocerans. At the cost of higher food concentrations (high K.-food levels) rotifers may exhibit high maximum growth rates (r.) and short times for their population development. These abilities increase with rotifer body size and render rotifers susce

The evolution and genetics of maturation in , mechanism serves to canalize size at maturity, and that this has consequences in form of higher variances for instar number and age at maturity. As the maturation phenotype is decoupled from variation in size at birth and variation in juvenile growth, variation in size at birth can evolve and be ma

Optimal energy allocation tactics and indeterminate growth: Life-history evolution of long-lived biverns may be investigated by manipulating the availability of resources and measuring the response of the organism. I review the literature of energy allocation in long-lived, iteroparous, indeterminately growing bivalves. I discuss the relevant time scales of allocation decisions (among-season vs. w

Ecology and genetics of interspecific hybridization in ,, such as size at maturity, intrinsic rate of increase (.), behaviour, and induction of helmets and spines. Hybrids tend to exhibit a combination of characters which enables them to persist in ecological niches which arise seasonally due to changes in predation and food regimes. Hybrids seem to be o
