Haptophytes are an environmentally important phylum of eukaryotic phytoplankton, forming the second most abundant algal group after diatoms in recent estimates ocean biodiversity. phylogenetically and functionally diverse, including globally distributed bloom-forming calcifying species such as Emiliania Coccolithus, non-calcifying orders that may form components phytoplankton communities polar ...

preserving genetic diversity of iranian native chickens is significant in order to perform breeding programs and improved production. genetic diversity among close populations can be determined by investigating their phylogenetic relations. different approaches have been applied to determine the phylogenic relations from which genomic sequencing has been considered the most functional approach....

the genetic diversity of 20 iranian populations of bunium persicum has been evaluated with random amplified polymorphic dna (rapd) and amplified fragment length polymorphism (aflp) markers. fresh leaves of seedlings from each population were used for genomic dna extraction. analysis of banding patterns of 15 rapd primers and 17 aflp primer combinations, revealed 192 (86%) and 228 (75%) polymorp...

Data from 247 global software development teams were used to examine the impact of temporal dispersion and leadership roles on the relationship between nationality diversity and team performance. Nationality diversity was positively related to team performance when project leaders regularly coordinate and monitor team members’ activities, and acted as mentors and facilitator. However, when nati...

The human genome is a complex, dynamic information system that encodes principles of life and living systems. These principles are incorporated in the structure of human genome sequence variation and are foundational for the continuity of life and human survival. Using first principles of thermodynamics and statistical physics, we have developed analogous "genodynamic tools" for population geno...

In animals, the population genomic literature is dominated by two taxa, namely mammals and drosophilids, in which fully sequenced, well-annotated genomes have been available for years. Data from other metazoan phyla are scarce, probably because the vast majority of living species still lack a closely related reference genome. Here we achieve de novo, reference-free population genomic analysis f...

Community structure has been widely identified as a feature of many real-world networks. It has been shown that the antigenic diversity of a pathogen population can be significantly affected by the contact network of its hosts; however, the effects of community structure have not yet been explored. Here, we examine the congruence between patterns of antigenic diversity in pathogen populations i...
