Article
Full-text available
Populations occupying peripheral areas of a current species range, particularly those located at rearing edges of the distributional ranges, have a high adaptive potential to environmental changes for the species, being of key conservation importance and, simultaneously, are heavily understudied. We provide the first description of the home-range s...
Article
Human-induced climate and land-use changes are important factors influencing global insect diversity. Nevertheless, the influence of weather on biodiversity is still relatively rarely studied. Grassland insects may be the taxon that is most affected by changing weather. We focused on the influence of weather and land-use management on butterflies i...

Full-text available
The Mediterranean is considered one of the richest biodiversity regions in Europe, and bats contribute to this species richness. Within the last two decades, certain bat species traditionally considered as representatives of the Mediterranean have spread northwards and colonized areas outside this region. In our study, we focused on ecological requ...

Oxbow lakes are specialised standing water bodies that often support unique macrophyte and animal communities. Between 2015 and 2016, we assessed the diet composition of adult rudd (Scardinius erythrophthalmus) in one such macrophyte-rich lake. Over 2016, we also undertook a series of feeding behaviour tests under artificial conditions, the aim bei...

Here we determine the distribution, numbers and habitat preferences of two of the largest species in the family Cervidae present in the Czech Republic, red deer and Eurasian elk. Red deer occurs predominantly in vast areas of forest, i.e. mainly in the mountains bordering this country and several large forest units in the interior. The range of thi...

The grass carp (Ctenopharyngodon idella Val.) is an important species used to control invasive aquatic macrophytes in many parts the world. In this study, we assess the diet of grass carp introduced to two artificial channels overgrown with aquatic vegetation. We examined forty 7+ to 9+ carp (517– 814 mm standard length) sampled in the summers of 1...

A thousand years old 105 cm deep deposit of bat guano in the Domica Cave (southern Slovakia, Slovak Karst National Park) has been discovered for science, and three samples were analysed for pollen to identify the bats’ preferred foraging habitats and for insect remains to identify their diet. The bat species concerned, Rhinolophus euryale, is rare...

Abstract. A complete list of bat records available from Libya was compiled from literature and from new records, based on field studies and examination of museum specimens. The record review is complemented by distribution maps, summaries of distributional status of the particular species, files of field data, findings on feeding ecology, observati...
Article
Full-text available
Winter bat census in hibernacula of the Muránska planina National Park was carried out in 2002–2013 and its results are presented here. In 37 roosts (out of 41 potential roosts checked, i.e. 90.2%) hibernating bats were found; altogether 19 bat species were recorded. Rhinolophus hipposideros was the most abundant and most frequent (D=62.6%, F=70.7%...
Article
Full-text available
The presented article introduces methods and some results of a project aiming to improve the protection of landscape permeability for migration of large mammals. The main aim of the project was delimitation of migration corridors, representing an ecological network connecting areas of existing, or potential presence of focal species. Based on mappi...
Article
Full-text available
We investigated a community of syntopically occurring horseshoe bats (Rhinolophus hipposideros, R. euryale, R. ferrumequinum) in southern Slovakia. The faecal pellets of these bat species were collected in the field and later analysed. under a dissecting microscope. The three species studied are known to be very similar as far as their ecology, ech...
Article
Full-text available
A diverse syntopic bat community was studied in Central Europe. The study was primarily aimed at forest bats utilizing a foliage-gleaning foraging strategy (Myotis nattereri, M. bechsteinii and Plecotus auritus). The results indicated the foliage-gleaning foraging strategy and the effective resource partitioning. Once a certain diet item comprises...
Article
Full-text available
The objective of the study was to describe the diet composition of western barbastelle bat (Barbastella barbastellus), its seasonal changes and main factors determining trophic niche of the species. Barbastelle bat feeds predominantly on moths and has the narrowest trophic niche within the entire studied bat community. A comparison of the food supp...

A complete list of bat records available from Iran was compiled from literature and from new records, based on field studies and examination of museum specimens. The record review is complemented by distribution maps, summaries of distributional status of the particular species, files of field data, findings on feeding ecology, and observations of...

Between 2001 and 2008, we recorded Myotis alcathoe at nine sites within three distant areas in the Czech Republic. The species identification was confirmed with cyt b sequences and four distinct haplotypes were identified. All the localities exhibit surprisingly uniform habitat characteristics: (1) old full-grown oak-hornbeam forests, with (2) nume...

In 2000–2002 bat droppings were collected under the emerging crevice of a nursery colony of Pipistrellus pygmaeus. The locality was situated in a floodplain forest at the confluence of the Dyje and Morava rivers (S Moravia, Czech Republic). In total, 27 samples (20 pellets in one sample) of droppings were used to analyze prey remains. In the diet,...

Full-text available
The monitoring and evaluation of changes in biodiversity is a subject for many biological and ecological disciplines. Biodiversity loss has become a social and political issue over the last few decades, and protection of biological diversity has emerged as one of the main subjects within national nature conservation policies as well as internationa...
Article
Full-text available
A complete list of bat records from Sinai was compiled, composed mostly of new findings from the field (85%). From the territory of Sinaitic peninsula, 106–111 records of up to 15 bat species are reported; viz. Rousettus aegyptiacus (Geoffroy, 1810) (10 records), Rhinopoma cystops Thomas, 1903 (1), Taphozous perforatus Geoffroy, 1818 (1), Nycteris...

Recent records of Nyctalus lasiopterus in central Slovakia are presented. Altogether, seven individuals were mist-netted in three sites there in 2005 and 2006. Data on the food composition and ectoparasites are added and the population status of the species in Slovakia is discussed.

A complete list of bat records available from Syria was compiled from literature and from new records, based on field studies and examination of museum specimens. The record review is complemented by distribution maps, summaries of the distributional statuses of particular species, files of field observations, reviews of taxonomy, and data on feedi...

A genetic analysis (402 bp of cytochrome b gene, 5’ end) of East-Mediterranean speci-mens of pipistrelle bats showed the occurrence of Pipistrellus pygmaeus in Turkish Thrace and P. pipistrellus in western Syria, respectively. No important difference in the examined gene sequences was found between P. pygmaeus from Turkey and those from other parts...
