Distribution of Shrews from Genus Sorex Linnaeus, 1758 (Mammalia: Insectivora) on the Territory of Republic of Moldova
The studies were accomplished between 2003-2007 in various natural and anthropogenic ecosystem types from different zones of R. Moldova. At the whole 127 Common shrews (Sorex araneus) and 98 Lesser shrews (S. minutus) were collected. Statistical, body and cranial morphological parameters were studied. S. araneus is common and the most spread species and more tolerant to the environment conditions and to anthropogenic activity by comparing to other shrew species. It was recorded in the majority of studied natural and anthropogenic biotopes (frequency = 94%). The lesser shrew is also rather spread all over the republic territory (frequency = 88%), but it is less numerous (abundance = 33% among shrews).

In November 2011 during a normal overwintering period, a small number of active, aquatic and semiaquatic adult insects were collected from several habitats along the Timiș River basin. This active state for the insects was closely related to higher temperatures found in certain deeper, stagnant water habitats, which also had greater amounts of aquatic vegetation and more stable living conditions. Most such habitats seem to be of anthropic origin, emphasizing the role of human impacts on the life of the discussed group of insects and the need to consider anthropic activities in the conservation of certain species of insects. The state of Aphelocheirus aestivalis is also discussed, along with a proposal to study the species on a larger scale and its possible inclusion on the Romanian Red List.
The paper focuses on land snail fauna from the upper Timiş River valley. The analyzed material originates from seven locations starting with the Trei Ape area (Semenic Mountains) and ending with Petroşniţa (upstream Caransebeş). Samplings were made during one campaign in August 2012. A total of 24 species was identified, belonging to 14 families. The area analyzed exhibits a reduced diversity due to the type of substratum represented by crystalline schist, the conifer dominated vegetation in the mountain area, and the anthropogenic impact of tourism, intensive grazing, cutting of woody vegetation in meadows and waste storage. The presence in Sadova Veche of the species Drobacia banatica, listed on Annex II of the EU Habitats Directive, underlines the importance of riparian habitat preservation for the conservation and dispersion of land snail species.

The aim of the research was to determine the concentration of selected macroelements in soil and in root crops (potatoes and fodder beets) at a variable soil reaction. The changes in pH values in the studied soils influenced the content of these elements in soluble forms determined in 0.1 mol HCl·dm-3. A statistical analysis showed a positive relationship between the soil pH value and the calcium and magnesium contents in a form close to the total form, as well as the content of soluble forms of phosphorus, calcium, and magnesium. The content of the studied macroelements, i.e. phosphorus, calcium, magnesium in the cultivated fodder beets and potatoes depended on abundance and form in which the studied elements occurred in soil, and also on specie and analyzed part of the plant. Along with the increase in pH values of the an increase in the phosphorus content and reduction of the magnesium content in the roots and above-ground parts of the beets were found. The calcium content in the roots increased along with an increase in pH of the soils, whereas direction of changes in the content of this element in the petioles and laminae of the beets was not unambiguous. A slight decrease in the content of the studied elements in the potato tubers (along with the increase in pH of the soils) was found.
Decapod associations have been significant components of marine habitats throughout the Cenozoic when the major diversification of the group occurred. In this respect, the circum-Mediterranean area is of particular interest due to its complex palaeogeographic history. During the Oligo-Miocene, it was divided in two major areas, Mediterranean and Paratethys. Decapod crustaceans from the Paratethys Sea have been reported in the literature since the 19th century, but only recent research advances allow evaluation of the diversity and distribution patterns of the group. Altogether 176 species-level taxa have been identified from the Oligocene and Miocene of the Western and Central Paratethys. Using the three-dimensional NMDS analysis, the composition of decapod crustacean faunas of the Paratethys shows significant differences through time. The Ottnangian and Karpatian decapod associations were similar to each other both taxonomically and in the mode of preservation, and they differed taxonomically from the Badenian ones. The Early Badenian assemblages also differed taxonomically from the Late Badenian ones. The time factor, including speciation, immigration from other provinces and/or (local or global) extinction, can explain temporal differences among assemblages within the same environment. High decapod diversity during the Badenian was correlated with the presence of reefal settings. The Badenian was the time with the highest decapod diversity, which can, however, be a consequence of undersampling of other time slices. Whereas the Ottnangian and Karpatian decapod assemblages are preserved virtually exclusively in the siliciclastic “Schlier”-type facies that originated in non-reefal offshore environments, carbonate sedimentation and the presence of reefal environments during the Badenian in the Central Paratethys promoted thriving of more diverse reef-associated assemblages. In general, Paratethyan decapods exhibited homogeneous distribution during the Oligo-Miocene among the basins in the Paratethys. Based on the co-occurrence of certain decapod species, migration between the Paratethys and the North Sea during the Early Miocene probably occurred via the Rhine Graben. At larger spatial scales, our results suggest that the circum-Mediterranean marine decapod taxa migrated in an easterly direction during the Oligocene and/or Miocene, establishing present-day decapod communities in the Indo-West Pacific.
