Opis:
W pracy przeprowadzono analizę miotów pochodzących od samic królików rasy nowoze- landzkiej białej (NZW) (n=55) i kalifornijskiej (CAL) (n=12) krytych samcami ras: belgijski olbrzym szary (FG), kalifornijska (CAL), burgundzka (BUR) oraz mieszańcami rasy nowo- zelandzkiej białej i belgijski olbrzym szary (NZW×FG). Zbadano czy istotny dla wyników reprodukcyjnych jest wpływ rasy matki, sezonu wykotu lub zastosowanego komponentu oj- cowskiego. Dokonano podziału samic w zależności od liczby miotów uzyskanej w okresie ob- jętym badaniami, otrzymując trzy grupy badawcze: samice od których uzyskano dwa mioty (n=21), samice od których uzyskano trzy mioty (n=15) oraz wszystkie samice (niezależnie od liczby uzyskanych miotów, n=67). Dla pierwszej grupy stwierdzono istotny wpływ rasy matki na liczebność młodych odsadzonych, średnio 5,20 oraz 7,33 sztuk odpowiednio dla rasy nowozelandzkiej białej i kalifornijskiej. Wykazano również, że w tej grupie najwyższą liczebność młodych odsadzonych uzyskiwano dla miotów z krzyżowań NZW×CAL (10,50). Wpływ rasy matki na efektywność odchowu stwierdzono w drugiej grupie samic, wykazując istotnie wyższą wartość dla samic rasy nowozelandzkiej białej (90,20%), niż dla samic rasy kalifornijskiej (69,84%). Analizy wszystkich uzyskanych w badaniu miotów wykazały istotne różnice pod względem liczebności młodych żywo urodzonych oraz odsadzonych w zależności od rasy matki (rasa nowozelandzka biała odpowiednio 6,59 oraz 6,34 młodych, rasa kalifor- nijska odpowiednio 7,71 oraz 7,50 młodych). W tej grupie zwierząt wykazano również, że zimą odchowywanych jest istotnie więcej królicząt (4,65) niż jesienią (2,00). Jednocześnie stwierdzono, że samice NZW kryte samcami FG dają mniej żywych królicząt w miocie (5,85) niż samice CAL kryte samcami BUR (10,00). Różnice zaobserwowano również w liczebności młodych odsadzonych, w miotach czystorasowych odchowanych było średnio 2,04 królicząt, natomiast w miotach z krzyżowań międzyrasowych od 5,39 do 10 królicząt. Oszacowane współczynniki powtarzalności dla samic, od których otrzymano trzy mioty wynosiły dla liczebności młodych urodzonych ogółem 0,36, natomiast dla liczebności żywo urodzonych

Opis:
Playgrounds and sandpits (small architecture objects according to the Construction Law) are subject to meticulous supervision, both at the design stage and subsequent status checks of the objects. One of the requirements arising from the need to protect playgrounds from animals is the necessity for fencing the object (Regulation of 31 December 2002 On Safety and Hygiene in Public and Private Schools and Institutions; Polish Standard PN-EN 1176 Playground equipment and surfacing). Does fencing playgrounds really reduce contamination of sand? To verify this hypothesis, the studies have been conducted on the residential areas’ sandpits, both fence secured and unsecured, located in close proximity to one another. The aim of the study was to evaluate the effectiveness of fences and nets as protection from microbial and parasite contamination of sandpits, mainly due to the access of animals to them. For several seasons of spring and sum-mer the sand was examined in terms of the total number of heterotrophic bacteria and fungi (organic matter contamination of sand indicators) and for the presence of coliform bacteria (including Escherichia coli), bacteria of the Salmonella genus and the eggs of intestinal parasites. It can be concluded that fencing playgrounds affects sand pollution less with waste and plant material (as a consequence, it has been reported statistically significantly less heterotrophic bacteria and fungi in the fenced sandpits’ sand). Unfortunately, the fence does not eliminate the risks associated with sand pollution of coliform bacteria. Cats and birds, but also dogs, still have a continuous access to sand. Due to the repeatedly stated carelessness of children and their caregivers, gates left open to the playground do not constitute an obstacle for domestic and stray animals. Another source of sand pollution with intestinal pathogens can be a manner of carriage of new sand, as there is no legislation governing the issue of transport. It has been visually found that the sand has been transported in a vehicle used for waste disposal.

Opis:
Artificial beaches, i.e. places in the public sphere, are usually intended for recreation, located at water reservoirs, rivers, and their surface is naturally occurring or applied sand. The urban bathing beach located in Szczecin by the Deep lake has sand purchased and distributed on the beach by the Municipal Services Office in Szczecin (a few hundred ton). The beach is divided into sectors, a volleyball court is in one part, in the next section catering and sanitary facilities are located, and the remaining area is a place intended for sunbathing and playing games. The aim of the experiment was to assess the effects of different ways of using the beach on changes of microbiological properties of the sand. The tests were taken from the beach sand in May 2013 (first term examinations), and in September, after several months of use (the second term of examinations). The sand was collected near catering and sanitary sector (the first object) and from the area of the volleyball court (the second object), as well as the playground for children (the third object). The facilities were distanced from the shoreline of the lake by approx. 8 metres. The comparison included the number of heterotrophic bacteria, fungi and the detected presence of coliform bacteria, including Escherichia coli, bacteria of the genus Salmonella and eggs of intestinal parasites. In any of the objects, or the periods of time, eggs of intestinal parasites and bacteria of the genus Salmonella were detected. The presence of coliform bacteria including E. coli was found in the sand collected from a catering-sanitary zone, there was also the biggest number of bacteria and fungi. The number of heterotrophic bacteria and fungi was similar in samples of sand taken from the volleyball court and from the playground, in this sand there was no bacteria belonging to the E. coli species, although in several samples from the playground other bacteria belonging to the coliform genus were detected. To sum up, it is possible to state that the same sand used in various ways is gaining different microbiological characteristics. The values of the studied parameters differed significantly with regards to sand taken from the area of consumption, hygiene-sanitary activities and sand collected from the area of active leisure (the court and playground). These results indicate the need for a deliberate selection of location for sunbathing (children playing in the sand) away from the sites for culinary and sanitary purposes.

Clusters of gastropod egg capsules, inferred to be of neritoids and attached to the inner shell wall of the ultimate whorl of a large volutid gastropod, are here recorded from the upper Nekum Member (Maastricht Formation; late Maastrichtian) of the ENCI−Heidelberg Cement Group quarry, St Pietersberg (Maastricht, southeast Netherlands). Because the aragonitic shell of the volutid has dissolved, the outlines of the egg capsules are now revealed on the steinkern of indurated biocalcarenite, having been subsequently overgrown by cheilostome bryozoan colonies and preserved as mould bioimmurations. This represents the first example of gastropod eggs preserved through bioimmuration, as well as the first record of gastropod eggs from the Cretaceous.

Opis:
A new species of a non-marine microconchid (Tentaculita) tubeworm, Microconchus hintonensis, from the Lower Carboniferous (Upper Mississippian, Chesterian) of West Virginia, USA, is described. Non-marine microconchids occur abundantly in the deposits of the Bluefield, lower Hinton, Princeton and Bluestone Formations of the Mauch Chunk Group, where they are either associated with land plant remains and bivalve shells, or are preserved loose in the host sediment. The specimens attached to plant remains and bivalve shells, are poorly preserved, but those occurring loose in the deposits are well-preserved in three dimensions. The interpretation pre sented here, is that the loose specimens of Microconchus hintonensis sp. nov. also originally encrusted plants (land plants, algae) and bivalve shells, but became detached after substrate degradation and dissolution. The association of land plant remains, charophyte gyrogonites, bivalves, ostracodes, conchostracans, and fish teeth and scales, and the concomitant lack of strictly marine fossils indicate that the microconchid-bearing deposits of the lower Hinton, Princeton and Bluestone Formations were deposited in fresh-water environments. Microconchus hintonensis sp. nov. is regarded as a highly fecund, opportunistic species that in large numbers colonized every available substrate in its habitat. Its abundance in the deposits investigated indicates that the species was welladapted to the environments it occupied, even during episodes of higher sedimentation rates and/or competition with other soft-bodied encrusters. During such episodes, microconchids were able to grow vertically by uncoiling and elevating their tubes, in order to escape potential burial and/or overgrowth by other encrusters.

Opis:
Investigation of mixed carbonate−siliciclastic Lower Devonian deposits have been carried out in the Ivanye Zolote and Ustechko sections in Podolia, Ukraine. Based on palynomorph evidence, the age of the samples studied is late Lochkovian, not older than the NM Oppel Miospore Zone, specifically the Si Lineage Zone. The presence of acritarchs and chitinozoans points to dominantly marine depositional conditions. However, a regressive environmental change toward more brackish conditions is indicated by a decrease in the taxonomic diversity of acritarchs in the topmost samples, the simultaneous disappearance of chitinozoans, and an increase in leiosphaerid frequency. Furthermore, evolution of limestone microfacies demonstrates a progressive transition from a shrinking marine basin toward a brackish, storm−affected muddy lagoon, manifested by recurrent profusion of impoverished, mostly opportunistic and euryhaline shelly benthos (nuculanid bivalves, leperditicopids and other ostracods, terebratulid brachiopods), chaetetid demosponges and diverse ichthyofauna. The association of plant (mainly nematophytes and some tracheids) and animal (eurypterid, ?scorpion, and possibly other arthropod) remains points to the presence of nearby Early Devonian wetland vegetation, providing food and shelter for various semi−aquatic and other terrestrial arthropods.

Opis:
The present article concerns a characteristics of enigmatic encrusting organisms of the order Microconchida (microconchids), similar to polychaetes of the genus Spirorbis, as well as a description of their finds from the Upper Carboniferous of the Upper Silesia region, southern Poland. The microconchids described here may represent the genus Microconchus. Most of the individuals encrust terrestrial flora and bivalve shells, and thus they certainly inhabited freshwater or, at most, brackish water environment. Similarly as the Recent polychaetes of the genus Spirorbis, the microconchids described here occur in association composed of both adult and juvenile individuals. The juveniles, however, dominate, what may indicate they have died due to some stress conditions (high rate of deposition and/or low oxygen content in the water). The microconchids are poorly-preserved. The original calcitic mineralogy of their tubes was replaced by phases similar to lead sulfide and dolomite.

Opis:
We report cyrtocrinid (Crinoidea) ossicles from the Rhaetian (Late Triassic) of the Tatra Mountains (southern Poland). The columnals are high, the facets are covered with thick crenulae and the latera are concave. Such features of symplectial articulation and latera distinguish them from the columnals of other Triassic crinoids (i.e., millericrinids and encrinids) and therefore we consider they belong to Cyrtocrinida. The oldest representatives of cyrtocrinids were known from the Early Jurassic, therefore the presented material constitutes the oldest world record of these crinoids to date. We speculate that perturbations related to the global mid−Carnian extinction combined with predation intensity observed in the Middle– Late Triassic have been involved in early origin of Cyrtocrinida.

Opis:
New collections of bryozoans from the Middle Jurassic (Late Bajocian and Bathonian) of Poland add significantly to our knowledge of the diversity and biogeography of the Cyclostomata at a time when they were the dominant bryozoan order in the fossil record. A total of 16 species and one form−genus (“Berenicea”) are present. Most are encrusters, predominantly on hiatus concretions. A single erect species was found in deposits interpreted as regurgitates of a marine vertebrate. The following new species are described: Microeciella annae sp. nov., M. kuklinskii sp. nov., M. maleckii sp. nov., M. mokrskoensis sp. nov., M. magnopora sp. nov., Reptomultisparsa harae sp. nov., and Hyporosopora bugajensis sp. nov. The taxonomic importance of the morphology of both the gonozooids and pseudopores is underlined, especially for encrusting species of the “Berenicea” type that are otherwise difficult to distinguish from one another. The described bryozoan assemblage encrusting hiatus concretions from the Polish Middle Jurassic is the richest that has been documented globally from this kind of substrate.

Opis:
The problemof application of pyrite framboids in reconstructions of the redox conditions is presented. The characteristics of pyrite framboids, their origin and principles of application in paleoenvironmental interpretations are given. The pyrite framboid diameter distribution as indicators of redox conditions was presented on the examples of the Middle Jurassic (Upper Bajocian-Lower Bathonian) ore-bearing clays of the Polish Jura, and Upper Devonian (Middle and Upper Famennian) dark grey and black shales from Kowala (Holy Cross Mountains). It has been shown, that during the sedimentation of the ore-bearing clays, the pyrite framboids formed in the sediment, below the oxic water column; however, some episodic oscillation around the dysoxic conditions cannot be entirely excluded. During the sedimentation of the Middle Famennian dark grey shales, the redox conditions at the sea-floor oscillated around dysoxia. In both examples, the framboids are characterized by wide range of their diameters and the presence of large, >10 "my"m, framboids. On the contrary, the Upper Famennian black shales, representing the Hangenberg event, were deposited below the euxinic conditions in the water column. It is indicated by a high frequency of small-size framboids, far below 6 "my"m in diameter, and the lack of the large ones. The overlying shales, on the other hand, show the transition to more oxic conditions. The redox conditions interpreted above are in agreement with the independent biomarker analyses and paleontological observations.
