In the temperate climate wild bees are the most important pollinator organisms. Pollination is essential for the communities of semi-natural habitats since this ecosystem service directly affects plant reproduction. The diversity of wild bees living in such areas is remarkably high, but they are susceptible to various anthropogenic influences.In our study, the composition and structure of wild bee communities were examined in Romania (Transylvania) at three semi-natural areas near Filia, Merești and Vârghiș. The surveyed areas were used as extensive meadows under relatively low but slightly different anthropogenic influence levels. We collected bees in these areas at several places (9 sampling points/area) by individual netting four times during the season. In the studied areas, 129 bee species were found, which makes up about 18% of the approximately 726 wild bee species registered in Romania. In addition to the high number of species, we also observed high diversity values. Our results showed that, even at our sampling site closest to the human settlements, the extensive use of the surveyed areas as meadows allows the development of diverse, species-rich bee communities.

Good environmental management needs evidence-based conservation measures, and those measures need both faunistical and ecological information. Following this path, for the first time in Serbia, a faunistical research of spiders at Subotica Sandland was organised in 2014 as a base for ecological arguments in landscape management of the area. The spiders were collected at ten different habitats on sandy soil, in the period from 27th April till 30th October by pitfall trapping and sweep netting. A total of 16304 adult and 7246 juvenile individuals were captured, and 225 species from 27 families were determined. Thirty species represent new records for Serbia. Diversity and species compositions provided an insight into the quality of the habitats and the influence of the conservation and development measures that were already applied. The main endangerment factors are outlined. Conclusions and suggestions according to the analysis of the spider fauna, are mostly in correlation with those made earlier based on other groups of organisms. Within the scope of nature protection, wet and sandy meadows are prioritised over the woods. For future monitoring, two flagship and umbrella species are suggested: Argiope lobata (Pallas, 1772) for the sandy area and Dolomedes plantarius (Clerck, 1757) for the wetlands.

Activity density is one of the most common measures for ground-dwelling arthropods including carabids. The term refers to the empirical fact that pitfall trap catches depend on the individuals’ activity; the higher activity of the individuals, the more catches in the traps. Although the movement at the individual level is widely studied, there is no available evidence whether the individual movement can be a good proxy for activity density. In our study, we aimed to explore this link in two ground beetle species, Carabus scheidleri and C. coriaceus, in oak-hornbeam forest in Hungary. We used pitfall traps for activity density and capture-mark-recapture and radio telemetry to record individual movement patterns in different forestry treatments, preparation cuttings and clear-cuttings, and their control plots. We identified an indirect link between activity density and movement of individuals via treatment types. Although activity density, mean walking speed, and the proportion of active time were significantly higher in both treatments than in control plots, individual movement reveals only temporal use of these habitats. Beetles left treatments within a few days. We concluded that the high turnover of individuals in treatments might indirectly suggest that these habitats likely act as temporary foraging sites for both species.

In this paper, we report for the first time two spider species for Albania, four for Bulgaria and two for Greece: Altella lucida (Simon, 1874) (Bulgaria), Eresus moravicus Rezac, 2008 (Bulgaria and Greece), Filistata insidiatrix (Forsskal, 1775) (Albania), Harpactea samuili Lazarov, 2006 (Greece), Loxosceles rufescens (Dufour, 1820) (Albania), Pritha parva Legittimo, Simeon, Di Pompeo et Kulczycki, 2017 (Bulgaria) and Pritha vestita (Simon, 1873) (Bulgaria). The recently described species P. parva is the first report for the Balkan Peninsula, while P. vestita is the first record for mainland Europe. Their congener Pritha nana (Simon, 1868) is removed from the Bulgarian checklist of spiders (misidentification). As a result of our report, the number of spider species increases to 571, 1049 and 1183 in Albania, Bulgaria and Greece, respectively.

The phylogenetic relationships among seven Callosciurus species from the Indochina Peninsula, including the C. honkhoaiensis which is endemic to Hon Khoai Island, were studied using complete mitochondrial cytochrome b gene sequences (1140 bases). We primarily focused on the phylogenetic position of C. pygerythrus, which is distributed in the western part of the peninsula. We identified two main lineages: 1) C. caniceps, C. honkhoaiensis, C. inornatus, C. phayrei and C. pygerythrus, and 2) C. erythraeus and C. finlaysonii. Estimated divergence time between the two lineages was at the junction of the Zanclean and Piacenzian in the Pliocene. Within the first linage, the divergence time of sub-lineages corresponded to the Pliocene-Pleistocene boundary, although phylogenetic relationships were unclear. These two divergence times estimated in the present study correspond to episodes of global cooling, suggesting that climate may have contributed to the divergence of these Callosciurus squirrels.

The goal of many agri-environment schemes (AES) is to increase biodiversity in agroecosystems. AES effects are often measured on invertebrates and birds; mammals as indicator species are infrequently targets of such researches. Our goal was to evaluate the local-scale effects of the Hungarian Agri-Environmental Measures (AEM) on the European brown hare (Lepus europaeus), which shows decreasing population trends across Europe. We compared hare abundances and their dropping numbers in AEM and control agricultural arable and grassland fields of 17 game management units in two seasons. We also examined the quality of arable fields based on their margin width and vegetation cover. We found that margin quality was higher in AEM than in the control fields. Control grasslands had higher vegetation quality than the AEM grasslands. We found a significant difference in hare counts between AEM and control arable fields in spring but no difference in autumn. The dropping densities did not differ in any season, treatment category or agroecosystem type. We conclude that the AEM program (2009-2014) in Hungary was not effective for the hare, and this might have been caused by the inadequate or weak application of AEM practices. We provide recommendations for future AEM programs to enhance biodiversity.

The life-history of an organism consists of its lifetime pattern of growth, development, storage, age, and reproduction. In this study, some life-history traits of Hyla savignyi were studied in populations from different parts of Iran. The microscopic and macroscopic analysis showed that testicular activity in H. savignyi is potentially continuous, reaching its peak level in April. Metamorphosis was completed in approximately 102 days after egg deposition, and body size at metamorphosis was 10 mm. Significant sexual size dimorphism was present in all populations, and a larger female asymptotic body size was observed (43.07 mm for females vs 41.16 mm for males). The adult survival rate (S) and life expectancy (ESP) were the same for both sexes (S = 0.73 and ESP = 4.2 years). Age and body size were positively correlated with each other for both females and males. Maximum longevity was recorded to be six years in both females and males, and ages of sexual maturity were estimated to be two or three years in breeding individuals. The adult sample age ranged from two to six years (mean age of females: 4.40±0.68 years; males: 3.63±0.13 years). Our data confirm the general patterns of body size variation and mean age in anurans and show that females are larger than males and live longer.
