The ecological importance of intraspecific variation
Nature Ecology & Evolution, 2017Human activity is causing wild populations to experience rapid trait change and local extirpation. The resulting effects on intraspecific variation could have substantial consequences for ecological processes and ecosystem services. Although researchers have long acknowledged that variation among species influences the surrounding environment, only ...

Intraspecific Variation in Cryptocaryon irritans
Journal of Eukaryotic Microbiology, 1997ABSTRACT. Intraspecific variation in the ciliate Cryptocaryon irritans was examined using sequences of the first internal transcribed spacer region (ITS‐1) of ribosomal DNA (rDNA) combined with developmental and morphological characters. Amplified rDNA sequences consisting of 151 bases of the flanking 18 S and 5.8 S regions, and the entire ITS‐1 ...

Intraspecific variation inEchinococcus: A biochemical approach
Zeitschrift f�r Parasitenkunde Parasitology Research, 1979In the present study, the soluble proteins of Echinococcus were separated by thin-layer isoelectric focusing in polyacrylamide gels (pH range 3.5-9.5), in order to determine whether inter and intraspecific differences can be detected by this technique. The two distinct species E. granulosus and E.

Intraspecific variation in parasites— What is a strain?
Parasitology Today, 1990The use of molecular techniques in parasitology has revealed a startling degree of diversity within species of parasite. These discoveries have emphasized the need for parasitologists to define and describe accurately the organisms with which they work.

Interspecific and Intraspecific Variation in Cercariae Release
Journal of Parasitology, 2009Given the importance of temperature for the shedding of trematode infective stages (cercariae) from gastropod first intermediate hosts, we investigated the response to temperature increases of trematodes of the intertidal snail Zeacumantus subcarinatus collected from different latitudes (differing in mean annual summer temperature) on the South Island ...

Intraspecific variation of isoenzymes in Taenia taeniaeformis
International Journal for Parasitology, 1995The technique of isoenzyme electrophoresis was applied to Japanese wild populations of Taenia taeniaeformis (isolated from Norway rats) and three laboratory reared isolates (KRN isolated from a Malaysian Norway rat, BMM from a Belgian house mouse and ACR from a Japanese gray red-backed vole).

Intraspecific flavonoid variation
The Botanical Review, 1987This review is concerned with variation of flavonoid patterns within species. Many examples of species with invariant flavonoid patterns are known; there are at least as many examples where complex arrays of pigments are known. Eight categories of variation are discussed: 1) qualitatively invariant pigment profiles, 2) quantitative variation, 3 ...

Intraspecific variation in the energetics of the Cabrera vole
Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2015Basal metabolic rate (BMR) is an intensively topic studied in ecophysiology for the purpose of understanding energy budgets of the species, variations of energy expenditure during their diary activities and physiological acclimatization to the environment.

Intraspecific variation in striatites spores
Journal of Palaeosciences, 1971Undispersed spores from sporangia of Arberiella were isolated to study variations in their form caused by compression and maceration in order to assess the systematic importance of such variations in the demarcation of species of Sporae dispersae. The effect of maceration was also studied in spores of two living conifers Pimts roxburghii and Cedrus ...
