Development of the fish assemblage in a restored river backwater
Hohausová, Eva
The restoration of the Kurfürst backwater was undertaken between December 1993 and November 1994. Already during the restoration, the number of fish species (>1+ fish) increased to 12, compared to 9 recorded before it. The following monitoring programme (1995-99) revealed further increases, up to 17 species. The structure of the fish assemblage, in terms of main species, reproductive and ecological groups, did not differ substantially between years, regardless of seasonal changes. Six species were newly recorded after restoration. Most species were found as both, 0+ and older fish, as many species probably spawned in or used the backwater as a nursery. The structure of the 0+ fish assemblage was also similar both before and after the restoration. After the 6-year monitoring, the restoration of the backwater can be considered as of benefit for the fish assemblage. Now, much will depend on the following development of the backwater, if it can further serve for local fish populations.

Millipedes (Diplopoda), centipedes (Chilopoda), terrestrial isopods (Oniscidea), and earthworms (Lumbricidae) of the Pálava Biosphere Reserve
Tajovský, Karel ; Pižl, Václav
The earliest records of millipedes, centipedes, terrestrial isopods, and earthworms from the territory of the Pálava Biosphere Reserve (BR) come from the thirties to fifties of the past century. However, the research on these invertebrates was carried out mainly in the adjacent floodplain of the Dyje River downstream to its confluence with the Morava River, covering only partially the territory of the present BR. An important milestone was the project aimed at the survey of terrestrial invertebrates within the extended BR, as recently under consideration (Rozkošný a Vaňhara 1995), in which all available faunistic records were summarised. Intensive soil zoological research carried out in the scope of the Global Environment Facility project as well as activities connected with biomonitoring in protected areas of the Czech Republic improved importantly the knowledge of the distribution of these invertebrates in the study area. At present, 23 species of millipedes (30% of species known in the Czech Republic) , 21 species of centipedes (29%), 16 species of terrestrial isopods (36%), and 19 species and subspecies of earthworms (36%) are known from the Pálava BR. The thermophilous character of many localities is manifested in the occurrence of the millipede Megaphyllum unilineatum, the centipedes Scutigera coleoptrata, Dignathodon microcephalus, and Henia illyrica, the isopod Trachelipus nodulosus, as well as of the earthworms Dendrobaena mrazeki and Kritodrilus auriculatus. The records of the millipedes Julus scanicus and Leptoiulus cibdellus in the wetland biotopes of the Křivé jezero National Nature Reserve, those of the terrestrial isopods Armadillidium versicolor in the Pavlov Hills, and that of Armadillidium zenckeri in the Slanisko u Nesytu National Nature Reserve, as well as the occurrence of the earthworms Allolobophora hrabei and Fitzingeria platyura in the Milovice Forest and Pavlov Hills are particularly important.

Neuropteroidea and Mecoptera of the Bohemian Forest
Zelený, Jiří
General information is given on the current status of knowledge of Neuropteroidea and Mecoptera in the Czech Bohemian Forest (Šumava Mts.), especially in peatbogs. In the Bohemian Forest, 2 species Megaloptera, 6 species of Raphidioptera, 48 species of Neuroptera (Coniopterygidae 10 species, Osmylidae 1 species, Sisyridae 2 species, Hemerobiidae 22 species, Chrysopidae 12 species and Myrmeleontidae 1 species) and 4 species of Mecoptera are known. The most common species are: Hemerobius pini, Conwentzia pineticola, Coniopteryx pygmaea Wesmaelius quadrifasciatus and Chrysoperla carnea.The species importatnt for the nature conservation and biological diversity are: Phaeostigma major, Puncha ratzeburgi, Aleuropteryx loewii, Coniopteryx esbenpeterseni, Parasemidalis fuscipennis, Osmylus fulvicephalus, Sisyra terminalis, Wesmaelius ravus, Micromus lanosus, Sympherobius pellucidus a Myrmeleon formicarius.

Updated list of stoneflies (Insecta, Plecoptera) of the Šumava National Park and Protected Landscape Area with regard to their species protection
Soldán, Tomáš
Update list of Plecoptera of the area in question consists of 75 species,18 genera and 7 families of the order including 5 species the txonomic status of which is unclear and respective historical records seem to be doubtful. Based on recent data,5 species, namely Brachyptera monilicornis (Pictet, 1841), Capnopsis schilleri (Rostock, 1892),Rhabdiopteryx acuminata Klapálek,1905,Nemoura sciurus Aubert, 1949 a Nemoura cf. babiagorensis Sowa,1964,are recorded from the Bohemian part of the mountains for the first time. Long-term data originating from the 1950´s of the past century enable to evaluate the status from their protection point of view (red list):3 species are extinct within the whole Czech Republic,5 species are extinct or missing in the Bohemian Forest (=Šumava Mts.) for more then 20 yearch,2 are critically endangered,6 endangered,7 vulnerable and 8 species are near threatened. Further 6 species show data deficiency and remaining 36 species still do not require any treatment.

Bark beetles (Scolytidae, Coleoptera) on spruce in the Bohemian Forest
Zelený, Jiří ; Doležal, Petr
The article summarized part of data, that were obtained during 6 years lasting research focused on bark beetles and their natural enemies in the Bohemian Forest (Šumava Mts). 26 species of bark beetles were collected from spruce samples that were brought from Modrava, Srní, Kvilda, Borová Lada etc. Despite many abundant pest species like Ips typographus, Ips amitinus, Pityogenes chalcographus a Polygraphus polygraphus, also three uncommon species were collected: Pityogenes conjunctus, Pityophthorus micrographus a Xyloterus laeve. These three species may have importance for nature conservation.

Natural enemies of bark beertle Ips typographus
Zelený, Jiří ; Lozan, Aurel
Totally 49 species of predators and 22 species of parasitoids are contributing to the population regulation of bark beetles, namely Ips typohraphus, in spruce forest of the Czech republic. The most encountered predators of bark beetles in our samples during 1998-2003 were: Thanasimus formicarius (Coleoptera), Medetera signaticornis and Lonchaea bruggueri (Diptera): hymenopteran parasitoids: Coeloides bostrichorum, Dendrosoter middendorfii, Cosmophorus klugii (Braconidae): Rhopalicus tutela, Roptrocerus xylophagorum, Tomicobia seitneri a Dinotiscus eupterus (Pteromalidae). The siricid wasp Ibalia leucospoides (Cynipoidea, Ibaliidae) is recorded too.

Biodiversity of staphylinid beetles (Coleoptera, Staphylinidae) in the Bohemian Forest - recent state, endangered species and their biotopes
Boháč, Jaroslav ; Matějíček, J.
More than 300 species of staphylinid beetles were found on 68 lokalities in the Bohemian Forest. 75 (23%) species of the all fauna belong to the Red list of the CR (5 critically endangered species, 27 endangered species and 43 vulnerable species). The most important biotopes for staphylinids in the Bohemian Forest are: petasites fringes of montane brooks, reedes and tall-sedge beds, foret springs, fens and transitional, mires, raised bogs, screes subalpine tall-forb vegetation, meadows and pastures, forest fringe vegetation, montane grey alder galleries, ravine dry pine, beech and spruce forests.

Leaf-spinning moths (Lepidoptera) feeding on Vaccinium uliginosum L. along an ecological gradient of the Šumava peat bogs
Spitzer, Karel ; Bezděk, Aleš ; Jaroš, Josef
The leaf-spinning moths (Lepidoptera: Tortricidae, Gelechiidae, Chimabachidae and Geometridae) associated with the boreal plant Vaccinium uliginosum L. were investigated in two different peat bogs (Mrtvý Luh near Volary and Chalupská Slať near Borová Lada). During four years (1998-2001) of collecting leaf spinnings, 19 species of moths were recorded from both peat bogs. The occurence of moths was structured along a distinct mesoclimatic gradient. Species closely associated with peat bogs (tyrphobiontic and tyrphophilous taxa) were found to be most abundant in treeless centers of both bogs in comparisonwith marginal parts.

Vývoj nezamestnanosti na Slovensku v rokoch 1993-2006
Čarnogurská, Ivana ; Krebs, Vojtěch (advisor) ; Kotýnková, Magdalena (referee)
Nezamestnanosť slovenskú ekonomiku postihovala už od počiatku 90.tych rokov a v jej priebehu sa zvýšila o 17,3 percentuálneho bodu. Nízka rozmanitosť socialistického hospodárstva a potrebná transformácia po roku 1989 boli hlavné dôvody prudkého nárastu počtu nezamestnaných. Od roku 2001 sa zvýšila podpora aktívnej politiky zamestnanosti aj vďaka ktorej došlo k zníženiu miery nezamestnanosti na súčastných 8,3%.
