Geographical specializations include cultures of Latin America, the Middle East, and the United States.
However, since stomach contents are snapshots of fish diets [ 23], we were unable to conclude if there is geographical prey specialization in P. straeleni.
The characteristics of lead investors (size, stage specialization, geographical location) and of the deal (amount invested, presence of multiple investors) are also investigated and are found to differently affect the post-buyout innovation activity of sample firms.
One concerns imbalances in workforce structure, whether from a functional specialization, geographical or facility lens.
A wide range of traits may be involved, including mobility, propagule pressure, environmental requirements (for example, resource and habitat specialization) and geographical range of species9,26,55.
However when, as a result of host specialization and geographical separation, discrete lineages were able to persist as separate diverging populations, then evidence of the divergence could be detected by comparing gene sequences from the separate populations.
These methods are illustrated by the analysis of both simulated data sets, which include ten loci evolving under a stepping stone model and a locus evolving under an alternative population structure, and a real data set focusing on the genetic structure of two nitrogen fixing bacteria, which is influenced by geographical isolation and host specialization.
Furthermore, a study on plant life history traits in rare versus common taxa also showed that infrequent species exhibited a narrower geographical range and more habitat specialization than their common relatives (Farnsworth 2007).
However, ecological and foraging specializations and distinct geographical distribution in relation to modern procyonids support classification in the separate family Ailuridae.
Moreover, since AS events are different at intraspecific level in several plant species, it was suggested that they may be correlated with niche specialization resulting from domestication in different geographical regions [ 18, 19].
