Increased Fluctuating Asymmetry in a Naturally Occurring Hybrid Zone between the Stick Insects Bacillus Rossius Rossius and Bacillus Rossius Redtenbacheri
The impact of interracial hybridization on fluctuating asymmetry (FA) and phenotypic variability (σ(2)p) in a presumed natural hybrid zone between the stick insects, Bacillus rossius rossius Rossi and Bacillus rossius redtenbacheri Nasceti & Bullini (Phasmatodea: Bacillidea), found on the Italian island Sardinia was investigated. The lengths of three bilateral traits and three unilateral traits...
متن کاملHybridogenesis and a potential case of R2 non-LTR retrotransposon horizontal transmission in Bacillus stick insects (Insecta Phasmida)
Horizontal transfer (HT) is an event in which the genetic material is transferred from one species to another, even if distantly related, and it has been demonstrated as a possible essential part of the lifecycle of transposable elements (TEs). However, previous studies on the non-LTR R2 retrotransposon, a metazoan-wide distributed element, indicated its vertical transmission since the Radiata-...
متن کاملJumping in a wingless stick insect, Timema chumash (Phasmatodea, Timematodea, Timematidae).
The stick insect Timema chumash belongs to a sub-order of the phasmids that is thought to have diverged early from other stick insects, and which is restricted to the southwest of North America. It jumps by rapidly extending the tibiae of both its hind legs simultaneously from an initially fully flexed position, unlike any other stick insect that has been described. The hind legs are 1.5 times ...
متن کاملDead Element Replicating: Degenerate R2 Element Replication and rDNA Genomic Turnover in the Bacillus rossius Stick Insect (Insecta: Phasmida)
R2 is an extensively investigated non-LTR retrotransposon that specifically inserts into the 28S rRNA gene sequences of a wide range of metazoans, disrupting its functionality. During R2 integration, first strand synthesis can be incomplete so that 5' end deleted copies are occasionally inserted. While active R2 copies repopulate the locus by retrotransposing, the non-functional truncated eleme...
متن کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
