Mediterranean plant karyological data – 31

AbstractOne flowering specimen of Ophrys bertolonii (s. str.) — a plant with a Circum-Adriatic distribution and hitherto unknown in other regions — was found on 7th May 2010 in the vicinity of Kunadacs (Central Hungary; N 47°00′ E 19°17′). The nearest known populations of this Mediterranean plant inhabit the Adriatic coast (ca. 450 km away) in Croatia, therefore this new occurrence represents a significant long distance dispersal event. The circumstances of the occurrence argue against introduction, but we can not decide now whether this new appearance is temporary or permanent. The permanent establishment of this strictly entomophilous plant requires the presence of its specific pollinator in the close neighbourhood of the habitat. However, no pollination was observed on the three flowers of the plant until 9th May, and one day later the stem had disappeared most likely due to grazing. Whatever the long-term fate of the plant is, this discovery represents a significant long distance (jump) dispersal event, and testifies to the dispersal ability of Ophrys species. Additionally, the appearance of a mature Adriatic plant in Central Europe fits well into the currently observed, climate change driven northward expansion of European orchids, therefore this finding most likely reflects a growing Mediterranean-like climatic influence in the region.

Mediterranean Plant

Abstract Coriander Coriandrum sativum L. (Apiaceae) is a year-round condiment and aromatic Mediterranean plant. It is cultivated in several countries in North Africa, in Europe, and Western Asia. In the El Harrach area of Algiers, the insect fauna visiting crop flowers includes Diptera (Syrphidae), Coleoptera, and Hymenoptera such as Chrysididae, Vespoidea, and Apoidea (Bees). The latter super-family comprises the majority of insect pollinators. Visiting bees belong to four families: Apidae, Andrenidae, Halictidae, and Colletidae. The main visitors are honeybees and six species of Andrenidae: Andrena flavipes, Andrena thoracica, Andrena lagopus, Andrena bimaculata, Andrena discors, and Andrena cinerea elliptica. The three species Andrena lagopus, Andrena bimaculata, and Andrena cinerea elliptica have 100% pollinating visits while Apis mellifera has only 63%. Andrena cinerea elliptica is the most frequent and the most abundant species.
