Sentence examples for models of pollen from inspiring English sources

This strategy offers the opportunity to improve models of pollen release and deposition and, more specifically, models of lepidopteran larval exposure to toxic Bt pollen and its subsequent effects.

The suite is designed as a platform for development of new models of pollen dispersal and deposition, and the production of simulated pollen data from maps of real landscapes for empirical tests of the model.

The recent developments within the use of models of pollen dispersal and deposition, and within the software needed in model applications, represent an important progress in the quantitative interpretation of pollen data in quantitative terms, for example, cover of wooded versus deforested land, of arable land versus grazing land.

Existing models of pollen tube behavior have focused on the physical processes that underlie tube growth, where cell shape, turgor pressure, internal ion gradients, and vesicle trafficking are essential considerations.

However, the underlying model of pollen dispersal and deposition assumes a flat landscape, which makes extending the approach to mountainous areas problematic.

This is an important consideration, and most modelling of pollen movement and cross-pollination has hitherto assumed that the predominant direction for pollen movement would also translate into the greatest directional degree of cross-pollination [20].

Recent developments in the modelling of pollen dispersal and deposition have led to the development of user-friendly computer software for simulating vegetation mosaics and pollen assemblages at specified points within those mosaics.

Modelling of pollen dispersal and cross-pollination is of great importance for the ongoing discussion on thresholds for the adventitious presence of genetically modified material in food and feed.

The recent advances in computer-based modelling of pollen dispersal and deposition through the POLLANDCAL (POLlen-LANDscape CALibration) network have enabled landscape simulations to be constructed and tested, both to validate the theoretical models, and to validate modelled landscapes using empirical data.

We therefore base our model on the Lockhart equation and use it to replace Darcy's law that had been at the base of an earlier model of pollen tube growth [34].

However, we emphasize that the model presented here aims at a general formalism for the modeling of pollen tube growth, i.e. the identification of the different coupled variables that govern the growth and their feedback [4], [14], [16], rather than a definitive model for the tube growth.
