However, in the further course of the action Tristan and Isolde’s love regains some of its absoluteness: for instance Heinrich refrains from taking over the quarrel of lovers from Eilhart. He plays a double game, on the one hand reducing the absoluteness and self-sufficiency of love, on the other hand building it up again and thus preventing the establishment of a firm doctrine in the course of the narrative (…), as neither the Arthurian court nor the love of Tristan and Isolde provides an absolute norm. Heinrich wrote his romance for the Bohemian noble Raimund von Lichtenburg, and the account of the foundation of the Round Table and the self-directed activities of the knights have belonged (…). The initial Arthurian ideal has become a confirmatory ritual for an exclusive body of noblemen – that matches the spirit of the knightly societies.

Rubus in Europe, its recent history, present state, and current problems. In general, the author follows the adherents of "Weberian batology" which in the last 25 years has assumed European responsibility for attempting to ciassify that particular genus. The thesis that not every bramble plant can be inciuded in the ciassification is accepted. The objective reasons for taxonomic difficulties within Rubus subgen. Rubus are connected with special features of taxogenesis of its members, especially with incomplete apomixis, frequent hybridization, splitting of the progeny into different morphotypes, resexualization, transitory existence of segregants, etc. The progress of the evolution of a new taxon in the given taxonomic group can be ranked: individual bush - local type - regional species - species with an extensive distribution area.

Recently, predation is named increasingly often as one of the key factors in contributing to the declines. A four-year research project (2001-2005) aimed to collect (as yet mostly nonexisting) data to provide a factual basis for this discussion. A country-wide inventory based on data for wader nests found by volunteers who mark nests for their protection from grazing/mowing indicated that above-average predation losses are found predominantly in the half-open landscapes of northern and eastern Netherlands, but also locally in the low-lying open grasslands which are the key areas for meadowbirds. Nest predation has increased in recent years, but the same is true for agricultural losses, at least in areas where no nest-protection takes place. At a local scale, predation losses vary greatly from area to area and from year to year. Temperature loggers in nest showed that diurnal and nocturnal predators contribute equally in total predation losses up to 50%, but higher predation losses are mainly caused by nocturnal predators. As many as 10 animal species were identified as nest predators on nests under surveillance with video cameras. Chick survival, investigated using radiotelemetry, was very low. About 60-80% were lost by predation, 5-15% by agricultural activities and 10-15% to all kind of other losses. At least 15 predator species were implied, with an apparently larger share taken by birds (notably Buzzard (16%) and Grey Heron (7-18%)) than mammals, with one exception: stoat (16%). Of the most-discussed predator species, Carrion Crows were W. Teunissen et al. Osnabrücker Naturwiss. Mitt. 32 2006 138 remarkably rarely involved in both nest and chick predation, while Red Foxes take a large toll of clutches in some areas, but not in others. Of all losses during the reproductive cycle about 75% and 60% was due to predation in Lapwing and Black-tailed Godwit respectively. Predation on chicks by birds had the largest effect on total breeding success, but at the same time elimination of this loss factor (if at all possible) alone would not be sufficient to establish a self-sustaining population. Predation seems to have become a factor of importance in some areas, in combination with already existing other losses. Our findings suggest that solutions to predation problems probably have to be found in locally/regionally targeted, specific action on multiple fronts rather than countrywide measures.

Other new records of indigenous taxa include Abacion Rafinesque, 1820/A. texense (Loomis, 1937) and Pleuroloma/P. flavipes, both by Rafinesque, 1820, from South Dakota, and Pseudopolydesmus Attems, 1898/P. serratus (Say, 1821) from Alabama, Connecticut, Delaware, New Hampshire, North Dakota, South Carolina, and the District of Columbia. New records of Aniulus garius Chamberlin, 1912, A. (Hakiulus) d. diversifrons (Wood, 1867), and Oriulus venustus (Wood, 1864) (Julida: Parajulidae) are provided for western Minnesota and/or eastern North Dakota. Published records from these states are summarized, and the introduced taxa, Julidae/Cylindroiulus Verhoeff, 1894/C. caeruleocinctus (Wood, 1864) and Paradoxosomatidae/Oxidus Cook, 1911/O. gracilis (C. L. Koch, 1847), are newly recorded from the Dakotas. The distribution of P. serratus, which extends from Maine to South Carolina and the Florida panhandle, west to Texas, and north to Fargo, North Dakota is described and discussed. This distribution exhibits a prominent southeastern lacuna which we hypothesize suggests replacement by younger, more successful species, as postulated for a similar distributional gap in Scytonotus granulatus (Say, 1821).

Males of S. idaho possess unusually complex gonopods, perhaps the most complex to be found in the Order Polydesmida. Snoqualmia is placed in context with other polydesmid genera known from North America. The polydesmid fauna of North America is discussed, as well as characters of the gonopods of the family.

Three additional species are noted for the Bahamian fauna based on specimens collected in the 1980s on other islands. Representative specimens are illustrated from North Andros along with genitalic images for species where these are not readily available in other publications. In addition, images of the larva and pupa are provided for a reared species for which the life history was previously unknown. Deborah L. Matthews; Jacqueline Y. Miller; Mark J.

In this paper, 9 new species from Vietnam are described and illustrated (Chimarra aculeata, C. carinata, C. corneola, C. insolita, C. mina, C. prominens, C. rostrata, C. undulata, and C. ungula). In addition, 3 new country records are noted (Chimarra areli Malicky and Mey, Chimarra pipake Malicky and Chantaramongkol, and Chimarra suthepensis Chantaramongkol and Malicky), and 1 new species group (minuta Group) is proposed and populated.

The data collected are presented here as illustrations of the puparia (fourth instar nymphal stages) and discussions of morphology as it relates to species and generic separations within this closely knit group of insects. A brief history of the pest outbreaks of B. tabaci is given and an overview of the important morphological characteristics of aleyrodine whiteflies is provided. Each of the eighty illustrations is accompanied by a discussion of the more important aspects of morphology.

This is based on data on species, genus, and family diversity for vascular plants and non-marine vertebrates. This paper presents data on genus level endemicity for the most speciose (but less well publicised) group of terrestrial animals: the beetles, with 205 genera (in 25 families) now recognized as being endemic (restricted) to the West Indies. The predominant families with endemic genera are Cerambycidae (41), Chrysomelidae (28), Curculionidae (26), and Staphylinidae (25). This high level of beetle generic endemicity can be extrapolated to suggest that a total of about 700 genera of all insects could be endemic to the West Indies. This far surpasses the total of 269 endemic genera of all plants and non-marine vertebrates, and reinforces the biodiversity richness of the insect fauna of the West Indies. Stewart B.
