Description of Preadult Stages (Protonymphs and Deutonymphs) of Discourella Radnaensis (Willman, 1941) Species (Acarina: Anactinotrichida: Uropodina) Discourella radnaensis species was described by Willmann from Slovenia, Radna city in 1941, the holotype being female. Since then, the species has not been collected, probably because Uropodina faunal studies in the Balkans were very few. Acarologic material was collected in Serbia, Djerdap National Park, Mount Veliki Strbac (768 m altitude), from litter of mixed deciduous forest and the bark of the decomposing trunk of deciduous trees. In addition to a female, individual protonymphs and deutonymphs were collected. Discourella radnaensis species is thus recorded for the first time in the fauna of Serbia, and pre-adult stages (protonymphs and deutonymphs) are described for the first time in literature.

The Chinese people discovered ginseng and used it as a revitalizing agent since time immemorial. They are still the world's major consumers of this plant drug. The commerical product of ginseng comes from two species of the genus Panax in the family Araliaceae. These species are P. ginseng C. A. Meyer which is the source plant of the Chinese, Korean and Japanese brands of ginseng, and P. quinquefolius L., which is the source of American ginseng. Phytogeographically, ginseng demonstrates the classical bicentric pattern of plant distribution, with closely related species in eastern Asia and in eastern North America. Ecologically, ginseng is an undergrowth of hardwood mixed deciduous forest. It prefers the northern or the northeastern slope of a hill. Species of the genus Tilia are good indicators of the proper environmental condition for the growth of ginseng. Morphologically, ginseng is a perennial herb with fleshy root, a single annual stem bearing a whorl of palmately compound leaves, and a terminal simple umbel of small 5-merous flowers. The flowers are soon followed by pea-sized fruits developed from inferior ovaries. The fruits are red when ripe. Ginseng is propagated by seed. The commercial products of ginseng consist primarily of roots 2-20 years old. Within this age range, the older the root the higher the market value, provided they are grown in proper conditions. The methods of curing the roots change the color and shape of the products. Chinese ginseng is prepared from roots bleached, boiled, steamed, sugared in curing. The cultural background for the uses of ginseng by the Chinese people is explained. Ginseng may be used alone in the form of tea, powder, or as a masticatory. It is also used in combination with other drugs of animal, mineral, or plant origin. Forty-two recipes are selected from Pen-ts'ao kang-mu and translated into English for the first time to show the various ways by which ginseng is used in traditional Chinese medicine. A systematic summary of the comparison plant drugs of ginseng is presented in the form of a table, showing the distribution of the species in the plant kingdom. The scientific names of the species are given in full.

AbstractThe mosquito Toxorhynchites rutilus septentrionalis (Dyar and Knab) is recorded for the first time in Canada. The species was found breeding in a water-filled rot cavity in a tree in the deciduous forest of Point Pelee National Park. The distribution of the species for which this record represents an extension of the range is discussed.

AbstractThe mosquitoes Anopheles barberi, Orthopodomyia signifera, and Orthopodomyia alba are recorded for the first time in Canada. All three species were found breeding in the water-filled rot cavities of trees in the deciduous forest of Point Pelee National Park, Ontario. Attention is drawn to the probable rarity of these mosquitoes in Canada and their conservation is recommended.

This is a report of a revision of 565 herbarium specimens of lichens, lichenicolous or non-lichenized fungi and additional locality records of common species produced from a visit of the Russian-Finnish expedition to Vodlozersky National Park right after its foundation in 1991. The analyzed collection and field records represent the earliest information about the lichen flora of the territory of the park. In total, 177 species are listed including 173 lichens, 3 non-lichenized and 1 lichenicolous fungi. Xylographa rubescens is new to the Republic of Karelia. Twenty two species are reported for the first time for biogeographic province Karelia transonegensis; 47 species for the Karelian part of Vodlozersky National Park; and 17 species for the whole territory of the park.

The annotated list of hepatics of the Sochi National Park includes 80 taxa. It is based on literature records and identification of 250 specimens collected by the authors. Scapania obcordata (Berggr.) S. W. Arnell and Calypogeia fissa (L.) Raddi var. intermedia (C. E. O. Jensen) Jorg. are new for the Caucasus, 17 taxa are new for Krasnodar Territory, 41 hepatics are reported for the first time for the park. New localities of 3 red-listed European species and of 6 species included in the Red Data Book of Krasnodar Territory are cited, indicating significant conservation value of the reserve.

The list of species is annotated with data on the species distribution in 55 collecting sites of 29 water bodies of the national park, and species abundance in collected samples according to Luknitskaya (2009). Among above mentioned genera, the genus Cosmarium is represented by the greatest number of species (20). Staurastrum chaetoceros has been found for the first time for the Novgorod Region.

A  multi-layer model (FORUG) was developed, to simulate the canopy  photosynthesis of a mixed deciduous forest during the growing season.  Measured photosynthesis parameters, for beech (Fagus  sylvatica), oak (Quercus  robur) and ash (Fraxinus  excelsior), were used as input to the model. This  information at the leaf level is then scaled up to the level of the canopy,  taking into account the radiation profiles (diffuse and direct PAR) in the  canopy, the vertical LAI distribution, the evolution of the LAI and the  photosynthesis parameters during the growing season, and the temperature  dependence of the latter parameters.
