The paleontological site of Cal Guardiola (UTM 31T DG1702), on the western bank of the Torrent de Vallparadís (Terrassa, Catalonia, Spain), was discovered in early 1997 during the construction of a socio-sanitary building next to the Mútua de Terrassa. A report on the geology and stratigraphy of Cal Guardiola was published by Berástegui et al. (2000), including a preliminary report on the fauna. This preliminary study suggested an estimated age for Cal Guardiola of ca. 1.0 Ma (Berástegui et al., 2000). Unpublished paleomagnetic analyses, carried out by Miguel Garcés, indicate a reverse magnetization for the sampled sediments, which can be correlated to below the Brunhes-Matuyama geomagnetic boundary (pers. com. of M. Garcés in Postigo Mijarra et al., 2007), thus being older than 0.8 Ma. This dating roughly corresponds to the later part of the Epivillafranchian biochron (1.2 to 0.9 Ma), which in Europe is best represented by the faunal assemblages from Untermassfeld in Germany, Le Vallonnet in France, and Colle Curti and Slivia in Italy (Palombo et al., 2008 and references therein). The faunal assemblage from Cal Guardiola represents one of the latest Epivillafranchian faunas from Europe and thus deserves particular attention for unraveling the chronology of the dispersal events that took place during the Epivillafranchian-Galerian turnover. However, thus far only the primate remains from Cal Guardiola have been published (Alba et al., 2008), while the rest of the fauna remains unpublished. Here we describe the carnivore remains from Cal Guardiola, which record one of the latest occurrences of the hyenidPachycrocutain Europe and further attests the coexistence of two distinct ursid lineages by the latest Early Pleistocene in Europe.

Abstract The Miocene-Pliocene (Turolian-Ruscinian) transition represents a fundamental interval in the evolution of Euro-Mediterranean paleocommunities. In fact, the paleoenvironmental changes connected with the end of the Messinian salinity crisis are reflected by a major renewal in mammal faunal assemblages. An important bioevent among terrestrial large mammals is the dispersal of the genus Sus, which replaced all other suid species during the Pliocene. Despite its possible paleoecological and biochronological relevance, correlations based on this bioevent are undermined by the supposed persistence of the late surviving late Miocene Propotamochoerus provincialis. However, a recent revision of the type material of this species revealed an admixture with remains of Sus strozzii, an early Pleistocene (Middle Villafranchian to Epivillafranchian) suid, questioning both the diagnosis and chronological range of P. provincialis. Here we review the late Miocene Suidae sample recovered from the Casino Basin (Tuscany, central Italy), whose taxonomic attribution has been controversial over the nearly 150 years since its discovery. Following a comparison with other Miocene, Pliocene, and Pleistocene Eurasian species, the Casino Suidae are assigned to P. provincialis and the species diagnosis is emended. Moreover, it is recognized that all the late Miocene (Turolian) European Propotamochoerus material belongs to P. provincialis and that there is no compelling evidence of the occurrence of this species beyond the Turolian-Ruscinian transition (MN13-MN14).

The faunal assemblage from the early Maastrichtian portion of the Horseshoe Canyon Formation is described on the basis of four new vertebrate microfossil localities and remains from the Albertosaurus bonebed. All of the localities sampled were deposited during a cool, dry climate at a palaeolatitude of ∼58°N. Thus, these assemblages provide insight into a northern cool-climate assemblage in the early Maastrichtian of western North America. This fauna is characterized by the presence of taxa with more northern affinities, such as Holostean A, champsosaurs, Troodon , and toothed birds. Warm-climate taxa, such as crocodylians, large and diverse turtles, and albanerpetontids are notable in their absence. The Albertosaurus bonebed locality at the top of unit 4 of the Horseshoe Canyon Formation was deposited during the initial stages of a trend to a warmer and wetter climate that is represented in unit 5. The bonebed shares many taxa with the underlying vertebrate microfossil localities. However, a notable difference is the presence of Atrociraptor marshalli from the Albertosaurus bonebed but not the other localities in the upper Horseshoe Canyon Formation. The presence of Atrociraptor may be attributable to this change in climate rather than local ecological conditions. Also, the assemblages are different in the paucity of fish remains in the bonebed, and the relative rarity of shed hadrosaur teeth. The low abundance of aquatic taxa and rarity of shed teeth of hadrosaurs indicate that the locality is largely autochthonous, with little material being transported into the site.

1. The results obtained for 236 Viennese schoolchildren between 11 and 12 years of age indicated that 38% of children had an increased concentration of cholesterol in their serum and 3% had an increased serum triglyceride concentration..2. The results of the preliminary study suggested that, by extending the dimensions of the screening, further problems, for example the correlation between different ‘risk’ factors and the significance of nutritional habits, might be studied.

Abstract Background: The speckled-pelage brush-furred rats (Lophuromys flavopunctatus group) has been difficult to define given conflicting genetic, morphological, and distributional records that combine to obscure meaningful accounts of its taxonomic diversity. In this study, we inferred the systematics, phylogeography, and evolutionary history of the L. flavopunctatus group using maximum likelihood and Bayesian phylogenetic inference, divergence times, historical biogeographic reconstruction, and morphometric discriminant tests. We compiled comprehensive datasets of three loci (two mitochondrial [mtDNA] and one nuclear) and two morphometric datasets (linear and geometric) from across the known range of the genus Lophuromys.Results: The mtDNA phylogeny supported the division of the genus Lophuromys into three primary groups with nearly equidistant pairwise differentiation: one group corresponding to the subgenus Kivumys (Kivumys group) and two groups corresponding to the subgenus Lophuromys (L. sikapusi group and L. flavopunctatus group). The L. flavopunctatus group comprised the speckled-pelage brush-furred Lophuromys endemic to Ethiopia (Ethiopian L. flavopunctatus members [ETHFLAVO]) and the non-Ethiopian ones (non-Ethiopian L. flavopunctatus members [NONETHFLAVO]) in deeply nested relationships. There were distinctly geographically structured mtDNA clades among the NONETHFLAVO, which were incongruous with the nuclear tree where several clades were unresolved. The morphometric datasets did not systematically assign samples to meaningful taxonomic units or agreed with the mtDNA clades. The divergence dating and ancestral range reconstructions showed the NONETHFLAVO colonized the current ranges over two independent dispersal events out of Ethiopia in the early Pleistocene.Conclusion: The phylogenetic associations and divergence times of the L. flavopunctatus group conform to demonstrated hypotheses surrounding the paleoclimatic and ecosystem refugium impacts on the evolutionary radiation of rodents dependent on stably humid conditions in the East Africa region. The overlap in craniodental variation between distinct mtDNA clades among the NONETHFLAVO suggests unraveling underlying ecomorphological drivers is key to reconciling taxonomically informative morphological characters. The genus Lophuromys requires a taxonomic reassessment based on extensive genomic evidence to elucidate the patterns and impacts of genetic isolation at clade contact zones.

Abstract. Andrechev A. 2020. Short Communication: Proportion faunal assemblage of rodents in geoecological districts of Mordovia, Russia. Biodiversitas 21: 3961-3968. In one natural area, animals may have different distribution. In some areas they inhabit, and in other areas, they do not inhabit. Scientists have been working on this issue for a long time. In this study reports that the species composition and distribution of species varies depending on geoecological districts. Twenty-eight rodent species have been recorded in the territory of Mordovia. The largest number of species in the region belongs to those living in coniferous and broad-leaved forests (42.9%). In the second place in terms of representation are species widely distributed in several natural areas (28.5%). They are slightly inferior to the types of steppe fauna (25%). The taiga type of fauna is represented by only 3.6% of the total number of registered species. For each geoecological district, the features of the rodent fauna are given and rare species are identified. The forest-steppe region of Mordovia is compared in rodent fauna with other regions of Russia with different typical faunal assemblages.

Fossils of freshwater Mollusca from the fluvio-lacustrine sediments of the Kathmandu Basin are collected from localities in the upper part of the Lukundol Formation, of Late Pliocene to Early Pleistocene age, and the Gokarna Formation, of Late Pleistocene age. Despite the temporal differences of the two localities, the dominant molluscan species in each locality are similar. The fossil molluscan fauna in the older Lukundol Formation is entirely composed of prosobranch gastropod shells belonging to the genus Bellamya and opercula of the genus Digoniostoma. The fauna in the younger Gokarna Formation includes similar prosobranch species with addition of one prosobranch species, along with three pulmonate gastropods, an unidentified terrestrial gastropod and a bivalve species. The additional prosobranch species belong to the genus Gabbia, and the pulmonate gastropods are of the genera Lymnaea, Gyraulus, and Planorbis. The only bivalve species belong to the genus Pisidium. In the Lukundol Formation, fossil molluscan shells are abundant but poor in number of species and the assemblage is dominated by lacustrine taxa preferring permanent lentic water body of shallow depth. Conversely, in the Gokarna Formation, species diversity is comparatively higher, with inhabitant of the shallow lacustrine to marginal less stable habitats. The fossil molluscan faunal composition is more similar to the recent fauna that inhabits the warmer southern Terai region of Nepal.

Sulawesi is known for its complex geological and biogeographic history, which is reflected in their extinct and extant faunal assemblage. Evidence of oldest terrestrial fauna in Sulawesi was found in the Early Pleistocene sediment and evolved since then. Despite being mostly isolated from the mainland Southeast Asia; four successive Proboscidean taxa have been found from the southern part of the island. The four taxa are: Stegoloxodon celebensis, Stegodon sompoensis, Stegodon sp. B, and cf. Palaeoloxodon namadicus, in which respective taxa are included in successive faunal stages. The aim of this research is to reconstruct the diet and palaeoenvironment of these Proboscidean taxa by incorporating stable isotope analysis with the fossil faunal record, geology, and stratigraphy. Stable carbon (δ13C) and oxygen (δ18O) isotope analysis were especially used in this study. Our result suggests that Stegoloxodon celebensis and Stegodon sompoensis were flexible feeders and were able to adapt to different niches, from closed canopy forest to open vegetation, while the diets of Stegodon sp. B, Celebochoerus heekereni and cf. Palaeoloxodon namadicus suggest that they were more specialized.

AbstractRecent developments in ecological theory pertaining to the coexistence of insect species in response to forest disturbance are reviewed, and the findings are applied to the requirements for the Biological Survey of the Insects of Canada. It is important that a data collection system have a sound theoretical base, otherwise it will probably be found inadequate for the purpose for which it was designed. Questions about changes in faunal assemblages should be related to the scale of disturbance relative to the replacement time of the forest. Recommendations for research on faunal assemblage disturbance relationships are made for the Forest Insect and Disease Survey of Canada, and for the northern boreal forest.

There is a growing emphasis upon psychiatric involvement in management of ‘non-sensical’ shop-lifters, those who steal items they neither want nor need However there is very little description of, or research into, psychological treatment approaches for this group of clients. We report a preliminary study of the process of therapy in two out-patient psychotherapy groups for female ‘nonsensical’ shop-lifters. Therapeutic factors in the group psychotherapy were evaluated using the method of Bloch et al. (1979) to assess the most important event in therapy. Results from nine subjects indicate that universality (realizing that one's problems are not unique) was rated as the most important aspect of therapy, with self-understanding the second most important. The implications of these findings for future provision and facilitation of therapy for this group of clients are discussed.
