Modern pollen dispersion models demonstrate quite good skills in representing timing of pollen seasons of trees, as well as variations of pollen concentrations during the season36,37,38,39,40. Comparatively simple but efficient parameterizations for pollen production and release were also described long ...
Pollen studies from small wetlands or bogs, so called “small forest hollows”, sensuJacobson and Bradshaw (1981), provide a finer scale resolution for use in conservation. Small hollows have been demonstrated in theory (Broström et al., 2005; Sugita, 1994) and practice (Calcote, 1998; Par...
Therefore, establishing the evolutionary origin of TPD by meiotic drive will require additional population-level data and modelling, so that other explanations for gamete killing can be excluded67. In practice, maize–teosinte hybrids are extremely vigorous with numerous tassels, so that these wind-...
collaborative practiceThe nutrients that workers derive from pollen provide all the proteins, lipids, vitamins, and minerals required for brood-rearing; the primary consumers of pollen are nurse bees which feed the brood. The greatest net increase in nitrogen content of bees is obtained when bees ...
Simple home remedies for hayfever and allergies8/12/2013 - More than 10 million Americans suffer from allergy and hay fever symptoms. Spring, summer and fall produce a wide variety of tree, flower and grass pollens. These pollens in turn create a wide variety of symptoms ranging from nasal...
and nuclear genes, which can be generally defined as the fre- quency clines with different (or the same) slopes (the rate for the change of frequency with distance) or positions (the geographical location for the same allele frequency) in space, was observed in practice (eg, Young, 1996)...
At Pollen Ventures, we have amassed a wealth of continually evolving business knowledge from our experience working on critical issues in high growth companies. We focus our practice in select areas of expertise, with a worldwide network of individuals, working collaboratively, who collect insights ...
They consist of simple sugars, minerals, vitamins, protein and fatty acids with a small percentage of other components. Therefore, the bee pollen grains are good source of healthy food due to their highly nutritious value. They should be natural without contamination for human consumption. The ...
Over the years, variations and improvements have been made to these networks, such as Fully Convolutional Networks (FCN) [61], and establishing best practice network architectures, such as VGG-16 and ResNet [62] [25]. However, more traditional ML approaches are used in microscopic pollen ...
The application of the app on real samples was conducted to show whether it also yields plausible results in practice. For this purpose, the study on the possibilities of (manual) chromatic assessment by Conti et al. [3] was reproduced. When comparing the results, it is noticeable that both...
