The City

AbstractIn 2016, we studied the occurrence of amphibians in 231 selected ponds in the city of Wrocław (Lower Silesia, Poland) and confirmed the occurrence of 10 species: Bombina bombina, Bufo bufo, Bufotes viridis, Hyla arborea, Pelobates fuscus, Pelophylax esculentus complex, Rana arvalis, Rana temporaria, Lissotriton vulgaris and Triturus cristatus. Among all studied sites, the most common were P. esculentus complex (146 occupied sites, 63.2%) and B. bufo (119, 51.5%), while the rarest was P. fuscus (8, 3.5%). The number of species at a single site varied from 0 (28 sites, 12.1%) to 9 (1 site, 0.4%). Frequency and mean amphibian species richness reached 87.9% and 2.7 ± 1.9, respectively. The composition of amphibian species did not change in comparison to previous studies conducted in the years 1997–2009, but declining trends in five species (B. bombina, B. viridis, H. arborea, P. esculentus complex, P. fuscus) were observed (28 compared sites). The results revealed that the permanency of ponds, their occurrence in the vicinity of river valleys, and a high ratio of watercourse length and green area around ponds are positively correlated and have a significant influence on amphibian species richness within the city. Thus, these identified factors should be considered in the course of sustainable urban planning in order to avoid potential conflicts between nature conservation and urban development.

AbstractMigration distances of eight species of amphibians were studied at 14 sites in the Czech Republic in the course of the 2007 spring migration season. Drift fences with pit-fall traps were installed at varying distances from the reproduction pond. No substitute breeding ponds were available nearby. 4423 m of drift fence was installed and data from a total of 4823 specimens were collected. The estimate 95th percentile migration distances for the newts Lissotriton vulgaris, Mesotriton alpestris and Triturus cristatus were between 105-866 m, and for the frogs Bombina bombina, Bufo bufo, Rana arvalis and R. temporaria estimates were between 170-2214 m. No adult individuals of R. ridibunda were caught out of water. With two exceptions in B. bufo there were no significant among-site differences in migration distances between L. vulgaris, T. cristatus and B. bufo. There were no significant between-sex differences in migration distances of L. vulgaris, M. alpestris, T. cristatus, B. bufo and R. arvalis. Thanks to a great number of various sites processed simultaneously and by the same methodology, presented data provide information on the overall distribution of migration distances in different habitats. The results could be used for the estimation of the extent of the influence on amphibian populations in cases of transection or other habitat degradation in the vicinity of their reproduction ponds.

Abstract The research was conducted in 2016–2017 in the 6,613-ha Kozubów Landscape Park (KLP). It focused on the occurrence and distribution of amphibians and reptiles, the biology and phenology of selected species and the existing threats. The KLP, established in 1986, is located in the Nida Basin, covering the eastern part of the Wodzisławski Ridge. This area is characterised by diverse landscape features formed on a chalk substrate. A significant part of the KLP (48.8%) is covered by forests growing on the tops and slopes of loess hills intersected by valleys and gorges. Hornbeam forests and fragments of riparian forests have retained a semi-natural character. The steep, non-forested slopes with a southern and south-western exposure are overgrown by thermophilic xerothermic grasslands. Xerothermic plant communities show a relatively low species diversity, because the main type of substrate in this area is loess. Two nature reserves, Polana Polichno and Wroni Dół, are located within the KLP borders. The following amphibian species were found in the KLP: smooth newt (Lissotriton vulgaris L.), great crested newt (Triturus cristatus Laur.), European fire-bellied toad (Bombina bombina L.), common spadefoot toad (Pelobates fuscus Laur.), common toad (Bufo bufo L.), European green toad (Bufotes viridis Laur.), European tree frog (Hyla arborea L.), edible frog (Pelophylax esculentus L.), pool frog (Pelophylax lessonae Cam.), moor frog (Rana arvalis Nilss.) and common frog (Rana temporaria L.). Reptiles are represented by the sand lizard (Lacerta agilis L.), viviparous lizard (Zootoca vivipara Jacquin), slow worm (Anguis fragilis L.), grass snake (Natrix natrix L.), smooth snake (Coronella austriaca Laur.) and common European adder (Vipera berus L.). The study also included the phenology and reproductive biology of common toad and common frog. Major threats to the herpetofauna are posed by grass burning. Unfavourable changes include decreasing water levels and drying out of water bodies.

On The Road

Abstract 69 road sections with amphibian mortality known from 2006 in Lviv Region (Western Ukraine) were repeatedly surveyed in 2017. 2078 dead individuals of nine amphibian species were detected and identified on the road surface (Triturus cristatus, Bombina bombina, Pelobates fuscus, Bufo bufo, Hyla orientalis, Rana temporaria, Rana arvalis, Pelophylax ridibundus and Pelophylax esculentus). The most numerous victims appeared to be B. bufo (72.8 %) and R. temporaria (22.6 %) which is almost the same as in 2006 (90.5 % together). However, the qualitative and quantitative composition has decreased in a decade (compare 3555 individuals of 13 amphibian species in 2006). As we suppose, the main reasons for amphibian population decline in the region are contamination, degradation and disappearance of the breeding ponds as well as the increased traffic intensity. According to the estimation of our research four B. bufo populations are under the excessive influence of roads and transportation, and need to be protected. One of these road sections was fenced up by temporary amphibian fences during the breeding migration (April 2018). Amphibian mortality on the fenced road section dropped down instantly: over thousand individuals of B. bufo and R. temporaria were caught alive into the bucket-traps and safely moved across the road.

The effects of illumination on the early development of four amphibian species — Lissotriton vulgaris (Linnaeus, 1758), Triturus cristatus (Laurenti, 1768), Rana arvalis (Nilsson, 1842), and R. temporaria (Linnaeus, 1758) — have been studied. In general, the rate of their early development is rather independent of illumination. The eggs of tailless amphibians develop almost similarly under any illumination conditions, whereas the eggs of tailed amphibians better develop at an illumination of 700 lx. Illumination mainly influences the survival rate of embryos and prolarvae, which increases at low light intensities and decreases in the dark. Possible mechanisms and causes underlying the observed facts are discussed.

In den Jahren 2006 bis 2010 wurde die Amphibienfauna auf der Grünbrücke bei Kiebitzholm (Schleswig-Holstein, Norddeutschland), an den angrenzenden Straßensäumen beidseitig der Bundesautobahn (BAB) A21 sowie an Stillgewässern im 1,5 km Radius um die Grünbrücke untersucht. Im Untersuchungsgebiet konn- ten sieben Amphibienarten festgestellt werden, darunter Knoblauchkröte (Pelo- bates fuscus), Kreuzkröte (Epidalea calamita) und Moorfrosch (Rana arvalis), die landes- oder bundesweit als bestandsgefährdet gelten. Bei Knoblauchkröte und Moorfrosch handelt es sich zudem um bundesweit bedeutsame Zielarten für den Biotopverbund. Teichmolch (Lissotriton vulgaris), Erdkröte (Bufo bufo), Grasfrosch (Rana temporaria) und Moorfrosch wurden im Untersuchungszeitraum auf der Grünbrücke nachgewiesen. Der Kammmolch (Triturus cristatus) konnte nur auf der östlichen Rampe festgestellt werden. Die Grünbrücke diente den er- fassten Individuen offenbar in erster Linie zur Querung der BAB A21 und nur zum Teil auch als Sommerhabitat. Eine auf der östlichen Rampe angelegte Wildtränke wurde im Jahr 2010 erstmals von Teichmolch, Kammmolch und Moorfrosch als Laichgewässer genutzt. Knoblauchkröte und Kreuzkröte waren im Untersuchungsgebiet besonders selten. Sie traten in einem bzw. zwei Untersuchungsgewässern auf. Während die Kreuz- kröte auf beiden Seiten der Autobahn gefunden wurde, wurde die Knoblauchkröte nur westlich der Straße erfasst. Die übrigen festgestellten Amphibienarten traten in teilweise größeren Populationen auf beiden Seiten der BAB A21 auf. Die Funde dieser Arten auf der Grünbrücke zeigen, dass bereits ein Verbund zwischen diesem Que- rungsbauwerk und den Populationen in der Umgebung realisiert war.

Trophic Niches

The feeding of four amphibian species (Triturus cristatus, Lissotriton vulgaris, Bombina variegata, Pelophylax ridibundus) was studied in 2011, in south–western Romania. The diet of the newts was uniform and mostly composed of aquatic preys The diet of the anurans was more diversified, comprising more prey taxa, mostly terrestrial. The trophic niches of the two newt species overlapped highly but differed from those of the anurans. The trophic niches of the anurans differed from one another. The differences among the four species’ diets were determined by the use of different trophic resources, originating from different environments, and by their different sizes. The newts’ diet was less diversified because the aquatic habitat was small and poor in trophic availability. The anurans used the aquatic habitat as a base from where they captured terrestrial preys in the surrounding terrestrial environment.

The results of faunistic surveys upon the amphibian and reptile populations in the Cozia National Park are presented. We recorded (found) 11 amphibian species (including the hybridogenetic Pelophylax kl. esculentus) and 12 reptile species; some species (Bufotes viridis and Emys orbicularis) were found after a long lapse in scientific recording. We observe that the Cozia Massif appears to have a richer herpetofauna than that of the adjoining Narâțu and Căpățânii massifs.
