Abstract Ecologists and fisheries scientists are faced with forecasting the ecological responses of non-stationary processes resulting from climate change other drivers. While much is known about temporal change, vis-à-vis species distributional shifts, less how spatial variability in population structure changes through time response to trends A experiencing decreasing would be expected more e...

Semicontinuous cultures of Lake Michigan algal assemblages were run at O.l5*day-’ dilution rates under P limitation for 41 days. In control cultures, nutrients were supplied to the entire culture once per day. In patch cultures, 10% of the cultures received a high concentration IO-min pulse each day. Patch and control cultures received equal nutrient flux and achieved equal biomass levels; howe...

the properties relevant to pharmacokinetics and pharmacodynamics of four series of synthesized s-triazine derivatives have been studied by quantitative structure-retention relationship (qsrr) approach. the chromatographic behavior of these compounds was investigated by using reversed-phase high performance thin-layer chromatography (rp-hptlc). chromatographic retention (rm0) was correlated with...

logistic regression (lr) was used to model urban growth between the years 1987 and 2001 in gorgan city, north east of iran. three groups of variables including economic-social, land use and biophysical variables were used in the modeling practice. using covariance of the independent variables, distance to administrative and sporting centers plus distance to cities were removed. roc (relative op...
