A preliminary list of the following four tephritoid families is provided including 30 Korean species, of which 12 are new to Korea: two Lonchaeidae, three Pallopteridae (two new to Korea), 17 Platystomatidae (two new to Korea), and eight Ulidiidae (all new to Korea). This list is mainly based on the insect collection at the Yonsei University Wonju Campus and on previous publications concerning ...
Rare hybridisations between deeply divergent animal species have been reported for decades in a wide range of taxa, but have often remained unexplained, mainly considered chance events and reported as anecdotal. Here, we combine field observations with long-term data concerning natural hybridisations, climate, land-use, and field-validated species distribution models for two deeply divergent an...
There is a long history of using both in silico and in vitro methods to predict adverse effects in humans and environmental species where toxicity data are lacking. Currently, there is a great deal of interest in applying these methods to the development of so-called 'adverse outcome pathway' (AOP) constructs. The AOP approach provides a framework for organizing information at the chemical and ...
In order to explore biodiversity of Fusarium species associated with the inflorescences of poaceous weeds, heads and inflorescences were collected from wild grasses in Ardabil province (Iran). Fusarium species were isolated using general and selective media. Pure cultures were established using a single spore technique. The isolates were identified based on morphological and molecular data. Seq...
The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
The genus Carex belongs to tribe Cariceae, subfamily Caricoideae and family Cyperaceae. This genus, with about 2000 species in the world and more than 50 species in Iran, is the largest genus among the family. In expedition to North West and West of Iran, two species, namely, Carex acuta and C. cilicica as new records and C. flava, C. rostrata and C. supina as reinvestigated species are reporte...
chromosome number, meiotic behavior, and pollen viability were analyzed in 2 species of genus solenanthus, s. stamineus (desf.) wettst. and s. circinnatus ledeb, from iran. this report is the first cytogenetic analysis of these species. all taxa are diploid and possess 2n = 2x = 24 chromosome number, consistent with the proposed base number of x = 12. although this taxon displayed regular bival...
Taxa are nonarbitrary classes whose existence is an empirical question and not a matter of mere semantic convenience. Taxometric procedures detect whether numerical relations between purported indicators of conjectured taxa bear the hallmarks of true taxa. On the basis of theoretical considerations, the current study tested whether taxa underlie sexual orientation and related measures of gender...
