Aegilops comosa(2n = 2x = 14, MM), is an annual diploid species belonging to the tertiary gene pool of wheat. It predominantly occurs in the coastal regions of Albania, the former Yugoslavia, and both coastal and inland areas of Greece1,2,3. As a diploid M genome donor species...
In aquatic macrophyte ecology, species abundance is usually estimated by cover values expressed on the ordinal scale. Recently, there has been increasing demand for three-dimensional estimates of plant abundance. To extend ordinal cover data into three dimensions, a new formula is proposed which ...

Thus the AM fungal TF-species abundance distribu- tion had a closer fit to the ZSM than any other model (ZSM: AIC ¼ 223.46; broken stick: AIC ¼ 392.11; log-normal: AIC ¼ 468.04). Analysis of variation partitioning between spatial (PCNM eigenfunctions) and environmental variables (...
The species of each insect found in a plot of cropland is: (1) a nominal variable (2) an ordinal variable (3) an interval variable (4) a ratio variable 5. The “average” type of grass used in Texas lawns is best described by (1) the mean (2) the median (3) the mode 6. ...

Let us write the chemical formula of a species of interest as where Z denotes the net charge. The average nominal oxidation state of carbon () of this species is given by (6) Eqn. (6) is consistent with the electronegativity rules described in [58] and is compatible with the equation...
Our study on ZIKV's species-specific characteristics involved cultivating the virus in Culex cells to find the viral elements responsible for this behavior. Sequencing of ZIKV, which had been passaged within a culture of both Aedes and Culex cells, uncovered the development of a substantial number...
Domesticated species are impacted in unintended ways during domestication and breeding. Changes in the nature and intensity of selection impart genetic drift, reduce diversity, and increase the frequency of deleterious alleles. Such outcomes constrain ou
The formula for the calculation is: ͯ ͯ1 n MAPE ϭ n At Ϫ Ft At tϭ1 where n is the number of possible abundance ratios (ten ratios for the five different states), At is the theoretical log2 value of the abundance ratio and Ft the median of the measured log2 ...
