Furthermore, when local farmers were asked about the origins of their varieties, a number of instances of seed exchange between villages and even between regions were noted.
Looking at some of the organisms identified from the BLAST searches (Additional file 13: Table S7), one can find very probable instances of gene exchange.
Based on the mismatch between morphology (species ID) and mtDNA or nuclear gene lineages, we identified 10 instances of gene exchange between described species, not including repetition at separate localities, involving nine described species (but see Discussion).
For instance, this is the case of exchange-type MCMC algorithms [53] for handling models with intractable partition functions.
For l-citrulline-saturated DM-PaDDAH, isolated instances of a significant exchange contribution to N transverse relaxation from exchange (Rex) at 800 MHz were detected for Thr71 (2.7 s–1), Leu145 (7.0 s–1), and Val160 (10.1 s–1).
They would have to calculate the benefits and losses, for instance, of intense exchange early on against the knowledge of their approaching annihilation, and against the demands of all the other tasks that needed doing.
As mentioned previously, it is important to remember faces of cheaters and cooperators alike to know who to approach and who to avoid in any future instance of social exchange [31], [42].
Reviewer 4: Gregory Morgan College of Artss and Letters, Stevens Institute of Texhnology, United States) Over the last two centuries, there have been many instances of the lateral exchange of ideas between biology and economics.
This pattern represents repeated, independent instances of unidirectional gene exchange between sub-populations in the upper Madeira and middle/lower Maderia and other adjacent Amazonas tributaries, likely following geodispersal of upper Madeira lineages facilitated by Andean orogeny, river channel meandering, and subsequent drainage capture.
In this paper, we propose an extension to the DAB model, called the multi-unit differential auction barter (MUDAB) model for e-marketplaces in which multiple instances of commodities are exchanged.
