“…Analysis of relationships between chemotypes, associated species and ecological factors A mutual information analysis Guillerm, 1969;1971;Gauthier et a!., 1975) revealed relations between the different ecological factors and the distribution of each species and each thyme chemotype. A second analysis was performed after transferring chemotypes to the list of dependent variables.…”

The present study shows that correlations exist between chemotype polymorphism, sexual polymorphism and the environment. These correlations fall into three categories: 1. a fairly tight correlation exists between soil type and chemotype structure of the thyme populations growing on it; with a soil change, a predictible chemotypic change occurs. 2. There is a clear correlation between a stable environment and low genetic diversity; conversely, in disturbed areas, high genetic diversity exists as indicated by higher outcrossing rates and high levels of chemotype diversity. 3. Thyme uses a strategy of low dispersal which allows, through individual selection, the precise specialisation of each population to its environment.

“…Except for the tidal level, all the variables were divided into 5 classes, incorporating a similar number of data. For each class of each of the variables, the frequency of occurrence of each taxon was converted to corrected frequency (CF) ( sensu Gauthier et al 1977). The CF is the ratio between the percentage of occurrence of a taxon within a class of an environmental variable, with the percentage of occurrence of this taxon in all the sampled sites.…”

Ecophysiological response of meiofauna to physicochemical gradients in intertidal sandy sediments

The spatial and ecophysiological preferences of the most abundant meiofaunal taxa inhabiting the sandy intertidal areas of NW Spain are characterised using ecological profiles methodology. Eh and water content are the best variables to explain the spatial distribution of most of the meiofaunal taxa. In general, most of the taxa show good agreement between the spatial and ecophysiological preferences, except for shear strength, mean grain size, carbonate, chlorophyll-a and depth. Eh and water content are the environmental variables that best explain the occurrence and densities of the majority of the meiofaunal taxa.Marine Ecology. ISSN 0173-9565
