Abstract Community structure of many systems changes across space in different ways (e.g., gradual, random or clumpiness). Accessing patterns species spatial variation ecosystems characterized by strong environmental gradients, such as estuaries, is essential to provide information on how respond them and for identification potential underlying mechanisms. We investigated filters (i.e., gradients that can include exclude local communities), predictors geographical distance between...
ABSTRACT The objective of the present study was to evaluate tolerance cadmium (Cd) sunflower genotypes grown in greenhouse conditions, and effectiveness using photosynthetic parameters as physiological indicators this tolerance. Seeds two previously identified tolerant (H358) Cd-sensitive (AG960) Cd were used. seeds germinated plastic cups containing plant substrate; after 9 days, seedlings transplanted basins a nutrient solution with 0 or 10 µM Cd, where they remained for 16 days. Samples...
The aim of this study was to evaluate the effects increasing concentrations lead (Pb) in nutrient solution on growth and macronutrient organic solute contents Helianthus annuus plants. experimental design completely randomized with four replications. dry mass yield not affected by treatments up a Pb concentration 0.6 mM, indicating that H. tolerant medium. reductions leaf, stem root masses at 0.8 mM were 74, 84 85%, respectively. Lead stress did reduce levels nitrogen (N), phosphorus (P)...
