A survey of breeding birds was carried out during the summer 1997-98 in several localities of the northern Danco Coast, Antarctic Peninsula. A total of 10 species were recorded: Pygoscelis antarctica (3234 pairs), P. papua (1888), Macronectes giganteus (76), Daption capense (61), Oceanites oceanicus (104), Phalacrocorax bransfieldensis (92), Ononis alba (15), Catharacta maccormicki (168), Lams dominicanus (583) and Sterna vittata (160 pairs).
”Bio” technologies are significant for the future prospects and for knowledge based bioeconomy in general. In the article we examine two areas of problems – one connected to the issue of use of genetic resources and traditional knowledge and another – connected to new plant breeding techniques. We examine whether the law is up to date with the developments in the area of biotechnology and if there is a need for legislative changes in these areas. As it turns out, the necessary legislation may be significantly behind the progress of bio-science. Also, we present potential paths for solving such problems.
Life cycles,number of eggs per female,minimal adult female length and reproductive costs are presented for 18 species of Amphipoda from the West Spitsbergen area, 77 79 °N. Fifteen species incubated eggs during the polar night and released their offspring in early April. Three species incubated eggs from late spring till late summer. The appearance of the youngest juveniles, indicating the hatching period, is presented for 63 species. Most of the species studied were K strategists, with large eggs of over 1 mm diameter; only one species (Hyperoche medusarum ) was r strategist.
The avifaunistic observations carried out in the tundra valley of the Sob River's upper course (west slopes of the Polar Ural) in July 1995 revealed the occurrence of 39 breeding and 8 non-breeding bird species. The most numerous were Anthus pratensis, Calcarius lapponicus, Phylloscopus trochilus and Anthus cervinus. The great variety of wetland and aquatic habitats had a decisive influence on species-richness and abundance of birds (jointly 30 breeding and 4 non-breeding species). Areas of low humidity were inhabited by 14 whereas anthropogenic habitats by 4 species. Most of them (except for eurytopic A. pratensis and C. lapponicus) occupied one-two habitats irrespective of their numbers. The density of Buteo lagopus was estimated at 1.67-2.00 p/10 km2. Three species of distribution ranges laying to the south from the study area, namely Bucephala clangula, Dendrocopos major, Circus macrourus, were noted in the valley. The results obtained have been compared with available data on the avifauna of the region concerned.
We discus legal status of plants obtained using NBT: whether they are to be treated as GMOs or not. The conclusion may have a negative impact on the development of research on them and their practical use. The problem of the application of provisions on GMOs in relation to the products of some of the NBT has been the subject of the decision of the Court of Justice of the European Union (CJEU) in Case C-528/16 – this topic is analyzed in details.
Water reservoirs are very valuable floristic sites in Poland. Among them, the most im-portant for preservation of biodiversity of flora are fishponds. The long-term process of human pressure on habitats of this type caused disturbance of their biological balance. Changes in the water regime, industrial development and chemisation of agriculture, especially in the period of last two centuries, led to systematic disappearance of localities of many plant species and plant communities. Gnaphalio uliginosi-Eleocharitetum acicularis Passarge 1999, of Isoëto-Nanojuncetea class Br.-Bl. et Tx. 1943, was firstly described in Germany. This association grows on sandy or sandy-gravely banks of rivers and in old river beds. In Poland, Gnaphalio uliginosi-Eleocharitetum acicularis has not been found so far. The patches of this type have been described many times, but otherwise classified acording to syntakxonomical system. During current vegetation research the association Gnaphalio uliginosi-Eleocharitetum acicularis was found in seven fish-breeding ponds in south-western Poland. Fieldworks were conducted in 2000–2016.
Rye is an important crop widely cultivated in Europe, but one of the hardest to improve due to its allogamy and self-incompatibility. The market for rye-based products is constantly growing thanks to the popularity of organic farming, feed production and diverse industry applications. To address these demands, new highly productive hybrid rye varieties are needed. Currently, full potential of heterosis in rye breeding is hard to reach due to the limited success in in vitro cultures. This review summarizes the progress in rye in vitro cultures and proposes novel approaches to overcome recalcitrance in this species.
