However, more recent work suggests that red maple, instead of declining, is becoming one of most abundant tree species in the Northeast (note: silver maple and Norway maple are much less common species in the region) (Fei and Steiner 2007; Pszwaro 2015).
Outside of about a half-dozen experts across the country, very few people can efficiently identify bees by genus, much less by species.
"Grey squirrel sightings accounted for less than 8% of animal sightings in [the Irish Midlands], which is remarkably low considering that they are a much less elusive species than either the red squirrel or the pine marten, and are also more commonly associated with human settlements".
Since there is much less Ni species than Fe, it is concluded that the spherical particles could consist of a γ-Fe2O3 core and a Ni2O3 surface layer.
However, many organisms have an enzymatic pathway, possibly to convert these intermediates more rapidly into allantoin, a much less reactive species.
We currently lack a vocabulary to precisely describe the degree of conservation of genic content and colinearity between any two species, much less across multiple species, although a gene-pair conservation terminology is currently in development (L. Feng and J. Bennetzen, unpub. res).
We observe much less within-species variation in iPSCs than in somatic cells, indicating the reprogramming process erases many inter-individual differences.
They found surprisingly high allelic variation in humans, whereas there was much less within-species variation in ape and monkey samples.
Using the LNS metric to compare our large S. bayanus expression compendium with a collection of published S. cerevisiae expression data, we show that gene expression networks are largely conserved between the species, though much less than within-species comparisons constructed by comparing different conditions.
We assume, however, that our morphological analysis based on a few colonies is fairly representative for the species as a whole, because measurement data on driver ants show that variation within and between populations of the same species is much less than variation between species (C. Schöning, unpublished).
