Data about Recent molluscan fauna of the Bažantnice u Pracejovic Nature Reserve are given. Altogether 32 species (27 terrestrial, 5 freshwater) were recorded. The Nature Reserve (geographical position see Fig. 1) represents a fragment of well-preserved alluvial woodland in the middle Otava River region. Woodland communities consisting of species with various relations to moisture of habitats dominate terrestrial molluscan fauna. The elements of aquatic habitats are poorly represented while open grounds species totally absent.

This paper brings a research of molluscan fauna of the Voděradské Bučiny, an important Nature Reserve near Jevany (Central Bohemia, Czech Republic). Altogether, 38 mollusc species have been recorded in the large complex of natural beech forest on the granite background. Rare woodland species Daudebradia rufa and Vertigo substriata were recorded here. Voděradské Bučiny reserve can be used as a model example of natural molluscan assemblage of acidic beech forest.

The results of a more than 50 years lasting malacological survey in the Mionší NNR are published here. The virgin forest of Mionší is one of the most important forest reserves in the Czech Republic and it presents the most preserved nature of the forest mountain habitats in the Beskydy Mts. Altogether, 62 mollusc species have been recorded there and we encountered 58 of them during 1998–2005. The molluscan fauna as a whole is characteristic for its high share of Carpathian species. Some of them reach a western limit of their occurrence there (e.g. Vestia gulo). The presence of virgin forest inhabitants (Macrogastra latestriata, Bulgarica cana, Acicula parcelineata) is of prime importance. Macrogastra latestriata, an index species of climatic Holocene optimum, has its largest population within the Czech Republic here.

The present paper summarizes all data on molluscan fauna from the Šúr National Nature Reserve between 1918–2005. It represents the largest Central-European remaining area of the autochthonous virgin alder swamp wood lying in a low basin (Carici elongatae-Alnetum Swickerath, 1933). Adjacent protected biotopes (flooded meadows, thermophilous Pannonian oak woods, forest-steppe-like shrub formations, drainage ditch and fishpond) were also surveyed. Altogether, 82 species in the target area were found during 1918–2005. In total we found 38 mollusc species (13 freshwater) in six biotopes in 2005; 24 species (7 freshwater) in alder wood; woodland and hygrophilous species were the most numerous. Presence of Viviparus acerosus, Anisus leucostoma, Pseudanodonta complanata, and Pisidium amnicum is dubious. Seven species new for the reserve were found (Carychium tridentatum, Arion lusitanicus, Deroceras rodnae, Cochlicopa nitens, Vertigo antivertigo, Cochlicopa lubricella, and Potamopyrgus antipodarum).

The excellent preservation of the molluscan fauna from the Gosport Sand (Eocene) at Little Stave Creek, Alabama, has made it possible to describe the preserved color patterns of 15 species. In this study the functional significance of these color patterns is tested in the context of the current adaptationist controversy. The pigment of the color pattern is thought to be a result of metabolic waste disposal. Therefore, the presence of the pigment is functional, although the patterns formed by the pigment may or may not have been adaptive. In this investigation the criteria proposed by Seilacher (1972) for testing the functionality of color patterns were applied to the Gosport fauna and the results compared with life mode as interpreted from knowledge of extant relatives and functional morphology. Using Seilacher's criteria of little ontogenetic and intraspecific variability, the color patterns appear to have been functional. However, the functional morphology studies indicate an infaunal life mode which would preclude functional color patterns. Particular color patterns are instead interpreted to be the result of historical factors, such as multiple adaptive peaks or random fixation of alleles, or of architectural constraints including possibly pleiotropy or allometry. The low variability of color patterns, which was noted within species and genera, suggests that color patterns may also serve a useful taxonomic purpose.

The results of fossil diatoms investigation from the deltaic sediments are presented. Samples were obtained from the core DM-1 and two Holocene outcrops from the Damchik region of the Astrakhan Nature Reserve. In the core samples eight periods of sedimentation based on diatom analysis were identified: the sediments formed in shallow freshwater basins and deltaic channels. The samples from the outcrops were investigated in much greater detail.

The Impact

Carlisle Museum's Natural History Record Bureau, Britain's first local environmental records centre, collected and collated records, mainly of birds but including also mammals and fishes, from amateur naturalists. It initially covered an area of 80 kilometres around Carlisle, and later from Cumberland, Westmorland and the detached portion of Lancashire north of Morecambe Bay: in effect the modern-day county of Cumbria. At the end of each year, those records which had been accepted were logged in a special “Record Book”, and a summary published. For the first eight years of its ten-year existence (1902–1912), these were printed in the local newspaper, The Carlisle Journal, but from 1908 they also appeared in The Zoologist. Alongside the Record Bureau, the Museum undertook a number of other activities, including a short-lived attempt to establish a bird-ringing project, an investigation into the impact of black-headed gulls ( Chroicocephalus ridibundus) on farming and fisheries interests (an early example of economic ornithology), the setting up of Kingmoor Nature Reserve and the protection of nesting peregrines ( Falco peregrinus), buzzards ( Buteo buteo) and ravens ( Corvus corax). The effectiveness of the Natural History Record Bureau and the reasons for its demise are briefly discussed.
