Avian fecundity in urban areas is a reflection of species-specific adaptability to urban resources, and to levels of nest predation and nest parasitism.
These variations could be a true reflection of species-specific differences in expression.
These speculations, and those drawn from other atomist sources, were often in the background of novel early modern reflections on species origins and their possible transformation in time throughout the eighteenth century (Bowler 2003, chp. 2; Oldroyd 1996; Greene 1959).
On the other hand, the topologies associated with newly expanded sets of duplicated white-throated sparrow genes (the para-orthologs of zebra finch TAS2R1 and TAS2R2) were not a simple reflection of the species phylogeny, with the genes tending to form species-specific groups (fig. 4).
This may partially be a reflection of the species' behavioral repertoire, which includes a large number of social behaviors [39] and relatively few food processing behaviors due to their limited dexterous manipulation [42].
The lack of response to TRAP was already regarded by Baumgarten et al. as a reflection of a species-specific thrombin receptor.
Finally, it is possible that the mitochondrial tree does not provide an accurate reflection of the underlying species phylogeny, a question that will need to be addressed using data from multiple nuclear loci.
Similarly, as a reflection of the potential confrontation of species, co-occurrence could also engender an interaction in the absence of a pre-existing one [9].
Sampling-site-based species accumulation curves (SAC) [ 34, 35] assess whether the total sample is an accurate reflection of the total number of species in the area of interest.
These results suggested that mutations in the srtA gene of laboratory strains Ingbritt and NG5 may be the consequences of long-term subculturing but are not a reflection of variation within the species in nature.
But especially this year as the 200th anniversary of Charles Darwin's birth and the 150th of his publication of On the Origin of Species excites widespread reflection and analysis among biophiles worldwide that pithy definition is particularly apt.
