Plant survival, growth, and flowering are size dependent in many plant populations but also vary among individuals of the same size. This individual variation, along with variation in dispersal caused by differences in, e.g., seed release height, seed characteristics, and wind speed, is a key determinant of the spread rate of species through homogeneous landscapes. Here we develop spatial integ...

We attempted to confirm that seed banks can be viewed as an important genetic reservoir by testing the hypothesis that standing (aboveground) plants represent a nonrandom sample of the seed bank. We sampled multilocus allozyme genotypes from three species with different life history strategies: Amaranthus retroflexus, Carduus acanthoides, Pastinaca sativa. In four populations of each species we...

We explore the effects of temporal variation in multiple demographic rates on the joint evolution of delayed reproduction and seed dormancy using integral projection models (IPMs). To do this, we extend the standard IPM to include a discrete state variable representing the number of seeds in the seed bank, density-dependent recruitment, and temporal variation in demography. Parameter estimates ...

Managing invasive species is inherently a spatial problem, even though the application of management is local. For efficient management of invasive species, we must therefore understand their spatial population dynamics. Once key demographic and dispersal rates are studied in detail, spatial population models can be constructed and utilized to evaluate the impact of various management options. ...

Plant species were collected in the botanical-geographic regions of Lankaran-Mughan and Lankaran lowland located on sou­thern part Caspian coast. During ecological-geobotanical studies we conducted southern coast, obtained information about morphological features systematic taxa wild flora Lankaran-Mugan botanical-geographical regions. In this article describe ecology distribution Dianthus cyri...
