Since alluvial meadows of river valleys of the Cnidion dubii are protected by the EU Habitats Directive, reconciling farmers’ demands for forage quality with the objective of maintaining them in good conservation status is an important issue in grassland research. In a long-term experiment from 2010 to 2018, we investigated the impact of fertilizing on forage quality and species assembly on a species-rich and twice-mown alluvial grassland in the Dessau Elbe floodplain (Germany). The experiment was composed of an unfertilized control, PK, N60, N60PK and N120PK applications. A significant improvement in forage quality was achieved by nitrogen fertilization only for crude protein, with higher feeding requirements for sheep met only in individual years. The legume cycle was inhibited by the application of nitrogen and high grass cover was maintained, but not increased, at the highest nitrogen application after an exceptional summer flood. The target forbs persisted in numbers over the study period in all treatments. For cover, the low-competitive target forbs responded neutrally to nitrogen fertilization, whereas detrimental effects were demonstrated for the competitive ones. Thus, we recommend not applying more than 60 kg year−1 of nitrogen and only in combination with phosphorus and potassium.

The Shannon Estuary in Ireland is home to a resident population of bottlenose dolphins (Tursiops truncatus) and is designated as a Special Area of Conservation under the EU Habitats Directive. It is an important industrial area, with numerous deep-water berths for shipping. Despite its high conservation value, there are few published studies on habitat use or foraging behavior of the Shannon dolphins throughout the year. The present study assessed the year-round presence and foraging activity of bottlenose dolphins at different locations in the middle and inner estuary using static acoustic monitoring. Dolphin presence was found to decrease with increased distance from the estuary mouth, i.e., where the estuary meets the Atlantic Ocean, while at the same time, foraging was found to be considerably higher in the upriver areas, suggesting the inner estuary was an important foraging area. Model predictions for seasonal, tidal and diel foraging were highly variable across locations, indicating that changes in dolphin behavior occurred over relatively small geographical scales. These results indicate that conservation efforts should consider the Shannon Estuary as a dynamic aggregation of habitats and future development initiatives should attempt to mitigate disturbance to the dolphins during important foraging periods on seasonal and diel scales.

Abstract The dioicous epixylic liverwort Cephalozia macounii (Aust.) Aust. is rare over its entire distribution area in the Northern Hemisphere. It is protected under the EU Habitats Directive and classified as critically endangered in Finland and Sweden. One reason cited for its rareness and the declining trend in its distribution its poor reproductive capacity. It does not produce asexual gemmae, which in general is common among liverworts. Although female plants with perianths are quite common, the male plants of the species have rarely been seen and sporophytes have not been described until now. In this paper we describe and illustrate the sporophytes of C. macounii on the basis of an old specimen collected in Southern Finland in the 1800s.

Metsamardikate (Coleoptera) uued liigid Eestis The article presents faunistic data on 85 species of Coleoptera new to the Estonian fauna. Most of the material has been collected within the framework of various research and monitoring projects carried out in Estonian nature reserves (1998-2009). A new type of trunk window trap, designed by the author in 2004 mainly for monitoring purposes, has been successfully used. 17 of the 85 species are new for the fauna of whole Baltic region: Pseudeuglenes pentatomus (Ths.) (Aderidae), Caenocara subglobosum (Muls. & Rey), Xyletinus tremulicola Y. Kangas (Anobiidae), Choragus sheppardi Kirby (Anthribidae), Cryptocephalus saliceti Zebe (Chrysomelidae), Dirrhagofarsus attenuatus (Mäklin), Hylis cariniceps (Rtt.), Microrhagus emyi (Rouget) (Eucnemidae), Gnathoncus communis (Marseul) (Histeridae), Notolaemus unifasciatus (Latr.) (Laemophloeidae), Agathidium discoideum Er. (Leiodidae), Anisoxya fuscula (Ill.) (Melandryidae), Mordellistena neuwaldeggiana (Pz.) (Mordellidae), Ripidius quadriceps Abeille de Perrin (Rhipiphoridae), Lissodema cursor (Gyll.) (Salpingidae), Aphodius quadrimaculatus (L.) (Scarabaeidae) and Eutheia schaumii Kiesw. (Scydmaenidae). One of the species, Caenocara subglobosum (Muls. & Rey) (Anobiidae), is new for the whole Northern Europe. Specimens of this species were collected from eastern and southern Estonia: most were caught in window traps but some also emerged from the collected fruiting bodies of Common Puffball (Lycoperdon perlatum). For 21 new species, Estonia lies on the northern edge of their range. Three of these, Triphyllus bicolor (F.), Mycetophagus ater (Rtt.) and Glischrochilus grandis (Tournier) that were collected from 6-10 sites, have a wider distribution in Estonia. Two species, Xyletinus tremulicola Y. Kangas (Anobiidae) and Stephanopachys linearis (Kug.) (Bostrichidae), have been listed on Annex II of the EU Habitats Directive. Two new species (Lymantor aceris (Lindemann) and Xyleborinus saxesenii (Ratz.)) were also added to the list of Estonian bark beetles (Curculionidae: Scolytinae).

AbstractThe Eurasian lynx Lynx lynx population in the Carpathian Mountains is considered to be one of the best preserved and largest in Europe and hence is a source for past and current reintroduction projects in central Europe. However, its status in Slovakia has been reported to the European Commission on the basis of hunters´ reports and expert estimates that have never been validated by a robust scientific approach. We conducted the first camera-trapping surveys to estimate the density of Eurasian lynx in Slovakia by means of spatial capture–recapture models in two reference areas during 2011–2015. We estimated population density per 100 km2 of suitable lynx habitat (posterior SD) as 0.58 ± SD 0.13 independent individuals (adults and subadults) in the Štiavnica Mountains and 0.81 ± SD 0.29 in Veľká Fatra National Park and surroundings. These are the lowest densities estimated using spatial capture–recapture models so far reported for the species, suggesting the lynx population in Slovakia is below carrying capacity. We suspect that low densities may be attributable to undetected human-caused mortality. Our results imply that official game statistics are substantially overestimated. Moreover, the lynx population in Slovakia may not be at favourable conservation status as required by the EU Habitats Directive. We therefore call for a thorough assessment of the density and trend of the Slovak Carpathian lynx population, and the establishment of a scientifically robust monitoring system.

AbstractAlthough various aspects of the biology of Anemone nemorosa have been examined, few studies present data on seed germination, and even then information tends to be rather contradictory. A. nemorosa L. is a spring-flowering, woodland geophyte, widely distributed across much of Europe. Germination phenology, including embryo development and radicle and shoot emergence, were investigated in one mountain and three lowland populations from northern Italy. Immediately after harvest, seeds were either sown on agar in the laboratory under simulated seasonal temperatures, or placed in nylon mesh sachets and buried in the wild. Embryos, undifferentiated at the time of dispersal, grew under summer conditions in the laboratory and in the wild. However, seeds did not germinate under continuous summer conditions. Radicle emergence in the field was first recorded at the beginning of autumn, when soil temperatures had dropped to c. 15°C in the case of the three lowland populations, and to c. 10°C at the mountain site. Shoot emergence was delayed under natural conditions until late autumn/early winter, when soil temperatures had dropped to c. 10°C in the lowlands and c. 6°C at the mountain site. In the laboratory, a period of cold stratification was required for shoot emergence, and this requirement was more pronounced in the mountain population. Seeds of the mountain population completed embryo development, radicle emergence and shoot emergence at cooler temperatures compared with the lowland populations. These results suggest that germination in A. nemorosa is highly adapted and finely tuned to local climate. We conclude that seeds of A. nemorosa display deep, simple epicotyl, morphophysiogical dormancy, and this is the first report of such dormancy for the genus Anemone. However, the continuous development and growth of embryos from the time of natural dispersal, and the lack of evidence of developmental arrest under natural conditions, suggests that radicles are non-dormant.
