Neodexiopsis Malloch (Diptera, Muscidae) is a member of the subfamily Coenosiinae, with more than hundred species recorded in Neotropical region. In Ecuador, it known by four species, which may be an underestimated number. We describe five new based on recently collected material: bicoloratta N. longialata nigrocalyptrata plana and secunda species. A key to segregating all from Ecuador presente...

Achene morphology of 49 taxa of the genus Centaurea L. was studied in terms of 19 different characteristics. On the basis of the variation in these features, some sections, such as sect. Cyanus with hairy hilum, were separated. Despite various differences, C. leuzeoides and C. gilanica were categorized in the section Psephelloideae, a section with lots of character variations within its species...

background: stearoyl-coa desaturase (scd) is a key enzyme that converts saturated fatty acids (sfas) to monounsaturated fatty acids (mufas) in fat biosynthesis. despite being crucial for interpreting scds’ roles across species, the evolutionary relationship of scd proteins across species has yet to be elucidated. this study aims to present this evolutionary relationship based on amino acid sequ...

aphid parasitoids (braconidae: aphidiinae) in several localities of kerman province, southeastern iran were studied between 2007 and 2008 and 20 species belonging to eight genera were identified. parasitoids were reared from 25 field-collected aphid species occurring on 31 host plant species. in the present study, 83 parasitoid-aphid-plant associations, their aphid hosts, and the respective hos...

During an exploration in boundary areas of Salmas (W Azarbayjan province, Iran) in 2016, an interesting plant from the genus Silene was collected. Determination of the plant material by using Flora Iranica was showed that, it is an unknown plant, but the specimen was determined as Silene armena Boiss. from the section Sclerocalycinae according to identification key of Flora of Turkey and Flora ...

Background: Stearoyl-CoA desaturase (SCD) is a key enzyme that converts saturated fatty acids (SFAs) to monounsaturated fatty acids (MUFAs) in fat biosynthesis. Despite being crucial for interpreting SCDs’ roles across species, the evolutionary relationship of SCD proteins across species has yet to be elucidated. This study aims to present this evolutionary relationship based on amino aci...
