Our study characterizes the biodiversity and conservation value of Peşteana peat bog, an upland mesotrophic peat bog, located in the Southern Carpathians, Romania. More specifically, we: (1) characterized the invertebrate (i.e., top soil, surface litter, and plant-dwelling) and plant communities along a humidity gradient in Peşteana peat bog and nearby habitats (i.e., treeline, ecotone, lowland and highland meadow, and forest), (2) assessed the main environmental factors driving the invertebrate community diversity and composition, and (3) determined the relationship between invertebrate community diversity and vegetation, focusing on the top soil invertebrates. Our study revealed a high diversity of invertebrates spanning...

We focused our research on two related anurans with similar ecological niches-Pelobates fuscus and P. syriacus-inhabiting the western Black Sea coast, at the limits of their ranges. We hypothesize that their differences in salinity tolerance are shaping the actual range limits in coastal areas, within the sympatry zone. We quantified experimentally the impact of salinity (range 0-9%) during early ontogeny to ask if salinity can modulate their coexistence, by affecting differently reproductive success and fitness. Exposure to salinity from egg to developmental stage Gosner 25 caused mild to severe malformations and affected survival and size in both species, but the impact was lower in P. syriacus compared to P. fuscus when exposed to salt concentrations of 6%. Embryos of either species did not survive the 9% salinity concentration. We expect that increases in salinization up to 6% could severely reduce the range of P. fuscus, but not P. syriacus, in coastal areas. These results are highly relevant for the conservation of P. fuscus, which is already declining across Europe.

We used between 13 and 15 variables to characterize the breeding ponds and their surrounding terrestrial areas. A total number of 14 amphibian species and a species complex were identifi ed in the two areas. In Târnava, the average species richness is larger in permanent ponds than in temporary ones. No signifi cant differences were found between the species richness in permanent and temporary ponds in Ciuc. In permanent ponds of both areas the presence of high traffi c roads in the vicinity (i.e. within an 800 m radius) explained more of the variation in species richness than the other habitat factors, whereas the presence of dirt roads accounted for the highest variation in species richness in temporary ponds.

In the present paper we synthesized the available distribution records from published papers, museum collections, and our own field data. These distribution data were treated separately as historical data (before 1990), continuous data (records from both before and after 1990), and recent ones (after 1990). Based on distribution records we performed a cartographic analysis consisting of 3 indexes that attempt to indicate shifts in geographic range over time. Using these indexes as a measure of the conservation status, we propose a Red List for the amphibians of Dobrudja based on the distribution data and the changes in species range before and after 1990.

We identified 86 species in 49 genera, with most taxa having restricted and clumped distributions. We estimated the sampling effort needed to identify a certain percentage of the total number of taxa based on species accumulation curves. While a good estimate of genus richness can be obtained with a relatively small number of samples, a greater sampling ...

These landscapes face an increasing pressure from human development and changes in agricultural practices. Pond-breeding amphibians and their breeding habitats are especially vulnerable to land-use changes. We studied waterbody use by amphibians in a rural landscape from Haţeg Geopark, Central Romania, a region where large areas are still under traditional land use. We surveyed 55 waterbodies, characterized them and their surrounding terrestrial habitats with 22 variables. Amphibians were more sensitive to waterbody-related variables than to landscape parameters. Man-made waterbodies had lower species richness than natural ones, but often represent the only breeding habitats available. The low importance of the landscape variables for amphibians is the result of traditional and environment-friendly land management, which maintains a mosaic landscape where the o...

Our study provides a detailed quantitative characterization of the advertisement call of P. subsigillatus , filling a gap in our knowledge of this genus, the most speciose among vertebrates. Males called perched on vegetation 0.5-2.5 m above ground, always during mild rain. The advertisement call is composed of a single note with a duration of 63-80 ms, with an initial short pulse (3-10 ms) followed by a longer tonal component. Call rates ranged between 4-12 calls/min. The dominant frequency varied between 2.02-2.82 kHz.

The monitoring of vegetation over a decade (2004-2014) underlines the turnover in specific composition of alien species, many of them with invasive character. The species accumulation curve is not nearing a plateau for native species, suggesting that the inventory is incomplete, but indicates an almost complete inventory for alien species. This result is supported by the incidence-based estimators of species richness that indicate an incomplete inventory, but show a higher percentage of missing native species compared to alien species. The estimated invasion rate during for the studied period was 2 species yearˉ1. Our study highlights the efficiency of long term extensive monitoring program, as a measure for rapid detection of invasive species.

Several sightings were within the harbor and the city of Constanţa, indicating that the otter can accommodate to and tolerate high human impact. The report is based on observations made between 2012 and 2015. The species has been previously reported from all Romanian regions but not from the Black Sea coast. The occurrences reported within this article confirm an extension of the range of this Near Threatened species on the Romanian Black Sea coast, most probably due to the increasing of population size from other sources such as the Danube floodplain.
