The pollen is faintly aspidate and the annulus is slight. Pollen grains of Corylus vary in size from 20-25 x 26-28 micrometers. Genus Distribution The shaded areas on the map indicates where the genus has been observed in the United States. - Native, observed in a county - ...
Sophisticated urban models have greater complexity and are able to simulate fine scale meteorological processes and fluxes in the city and on the district, or even building level. Sophisticated urban schemes could improve the simulation of the urban local-to-regional interactions, e.g. the ...
Beyond single species, effects at the ecosystem level have to be considered, too (Obrycki et al. 2001). Potential toxic effects are determined by the amount of exposure to the Bt-toxin and therefore to the amount of Bt-maize pollen, respectively. Dispersion and deposition of maize pollen ...
which are also well-known ancient sites. Glastonbury is to the west of Stonehenge. From the map, it appears to be about 35 miles away. Crop circle formations often appear near such sites; and in some cases, right next to them.
Me, meiotic stage; Me1, meiotic leptotene stage; Me2, meiotic zygotene-pachytene stage; Me3, meiotic diplotene-tetrad stage; MP, mature pollen stage; PMe, pre-meiosis; TG, tricellular pollen stage; UG, uni-cellular gametophyte stage. Yellow color in heatmap indicates high level of expressio...
We used Generalized Linear Mixed Models (GLMM), allowing for a binomial distribution and random effects, to analyse the level of unreduced pollen production in all three populations. This choice was motivated by the fact that our discrete proportion data violated the linear model assumptions of nor...
The genomic location and stage-specific expression pattern of many long non-coding RNAs reveal their critical role in regulating protein-coding genes cruci
(MTCO), accumulated temperature during the growing season (an index of growing season warmth) measure by growing degree days above a base level of 5°C (GDD5), mean annual temperature (MAT), mean annual precipitation (MAP) and a moisture index (alpha, α) defined as the ratio of actual...
When the landfill use comes to end, important subsequent steps include aftercare, safety assurance, and ecological regeneration. Landfill revegetation is cost-effective and eco-friendly approach in the management of landfill areas, which serves the purpo
In the next phase, the level of organic carbon drops suddenly, while dissolved N and P accumulate in the water surrounding the pollen grain. The papers by Rösel et al. [37] and Filipiak [47] show that the presence of SPM, rich as it is in carbon, nitrogen and phosphorus, has a ...
