Essential oil composition of endemic Tanacetum zahlbruckneri (Nab.) and Tanacetum tabrisianum (Boiss.) Sosn. and Takht. from Turkey.

In this study, water-distilled essential oils from the flowers of Tanacetum zahlbruckneri and flowers and stems of Tanacetum tabrisianum from Turkey were analysed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The flower oil of T. zahlbruckneri was characterised by the sesquiterpenes germacrene D (29.7%) and spathulenol (12%). Flower (A) and stem (B) oil of T. tabr...

Biosystematics and phylogeny of Tanacetum fisherae, a new record from Iran

The chromosome number (2n=5x=44+1B) of Tanacetum fisherae, as a new record from high mountains of southern Iran (Kerman province: Hazar mountain) is reported. A new ploidy level (pentaploidy) for the genus is presented for the first time. The studied population was aneuploid, having lost one chromosome out of the 45 expected in an x=9-based pentaploid. The distribution map, description and micr...

Genital morphology and mating behaviour of Allostethus (Dermaptera), an earwig genus of enigmatic phylogenetic position

In the suborder Forficulina (order Dermaptera; earwigs), the families Apachyidae, Anisolabididae, and Labiduridae form a possibly paraphyletic assemblage Mesodermaptera, which is characterized by laterally paired penes that point in opposite directions (anterior and posterior) when in repose. A previous study of a labidurid species, Labidura riparia (Pallas, 1773), revealed that males predomina...
