Shape differentiation resulting in specialization to benthic and limnetic niches is expected to have evolved in these species pairs, but whether similar genetic changes underlie the evolution of body shape in different replicate lakes is unknown.
As a result, specialization tends to be underestimated in small sample sizes.
Perhaps the varying needs of Atget's clients helped him avoid the formulaic solutions that often result from specialization.
For simplicity, we will refer to the structural entities that result from specialization, be they offices, regional office systems, or practice areas as organizational units.
We failed to detect the phylogenetic signature of endemic clades that would result from specialization and adaptive radiation within this habitat.
Such incompatibility, or competition for specific sequences along the genome, would result in specialization of each of these selfish units to each of these diverse sequences.
Taken together, our results suggest strikingly rapid evolution and high retention of recent duplicates in zebrafish in a manner likely to result in specialization of immune and sensory mechanisms.
First, selection with a single antibiotic resulted in specialization, that is, the direct response (resistance improvement on the antibiotic used for selection) always exceeded the correlated response (resistance improvement on the other antibiotic).
Global patterns of marine diversity have been, so far, studied in groups with high habitat specialization, resulting in conflicting patterns.
Alternatively, this over-recruitment may represent a breakdown in functional specialization, resulting in impaired cognition (Logan et al. 2002).
