The paper summarizes numerous scattered data from the last 120 years on the former distribution of the brown bear (Ursus arctos) in Bulgaria. Data from 52 (13 fossil and 39 subfossil) sites (from the Middle Pleistocene to the 19th century AD) are presented. The brown bear former distribution was…

The paper summarizes all scattered data from the last 116 years on the distribution of the Late Pleistocene cave hyena in Bulgaria, a part of them unpublished. Data from 24 fossil sites (Middle Pleistocene – Late Pleistocene) in the country are presented. The fossil record in Bulgaria proves the…

In 2020, an extremely high mortality of juveniles was recorded in a nursery colony of Myotis myotis at Žihobce (Klatovy Dist.), reaching 50.6% of the potential growth. Most juveniles died within two weeks of age (67.4%). The cause of this phenomenon is not known. The results of chemical…

There is a lack of precise guidelines concerning the survey effort required for advanced bat surveys in temperate European woodlands, resulting in a lack of standardisation in survey methods. In this study we assess catch data from 56 bat trapping surveys at 11 UK woodland sites in order to provide…

The western barbastelle, Barbastella barbastellus (Schreber, 1774) is a species protected by national and international agreements. The number of records on its occurrence in Turkey is very limited, and the species is not well-known. Records in literature, except for the ones from Adıyaman (owl…

This study addressed the question whether it is possible to clearly differentiate between wild and tabby domestic cats on the basis of hairs (guard hairs in particular). The colour banding pattern of individual hairs is studied in this context for the first time. Also, hair length and width, as well…

Based on 25 records (both published and new) we summarize the recent distribution of Pipistrellus kuhlii in the Czech Republic and discuss possible colonization routes. The species colonized a major part of the Czech Republic during 14 years since its first record in 2007. Based on…

This paper provides an updated information on the composition and distribution of the rodent fauna of Iraq. The data were taken from field observations that were conducted during the period 2018–2019 in addition to the previous literature and museum collections data. The rodent fauna of Iraq…

The study describes changes in the Hungarian population of the European ground squirrel (Spermophilus citellus) that occurred between 1950 and 2019. Data before 1990 were collected from local communities who were familiar with this mammal (an example of citizen science). The comparison was based on…

In the years 2012–2017, we studied the annual and diel temporal activity patterns exhibited by female Geoffroy’s bats (Myotis emarginatus) during reproduction by using an infrared light barrier system, videotaping with an infrared camera and sporadic direct counts of juveniles in the roost when the…

The bat survey in the Greek part of the Prespa basin in 2018–2020 confirmed, despite the limited methods used, its extraordinary importance for bat diversity. The study documented the presence of 22 bat forms (20 species) by acoustic surveys and a favourable status of some roosts including several…

At the turn of the 19th and 20th centuries, 54 Przewalski’s horses were imported alive to Europe in five transports. Only twelve of them (6 ♂♂, 6 ♀♀) have bred. The earliest birth occurred in a mare at the age of five years and the oldest mare gave birth at the age of 17 years, always during the…

The presence of the Eurasian otter (Lutra lutra) in the wild of the Czech Republic has long been the subject of discussions between the nature conservation on the one hand and the production and sport fishermen on the other. The methodology of obtaining data on the otter abundance is one of the…

The syndrome of ear pinnae absence was recorded in three individuals of the black rhinoceros (Diceros bicornis) among 71 observed (4.2%) in the Etosha National Park, Namibia, during eight visits in 2013–2020. In two cases, the syndrome comprised bilateral absence of the pinna and certain damage of…

This paper briefly reviews the taxonomic history of the Plecotus kolombatovici complex, the bat populations which occur in isolated ranges surrounding the Mediterraean Basin, including Maghreb, Tripolitania, Cyrenaica, Anatolia, Balkans, and Italy, plus numerous Mediterranean islands. Since this…

On 28 January 2020, three living individuals of the Leisler’s bat, Nyctalus leisleri, were found in a shed in Malaucène, southern France (44°11’34”N, 05°07’26”E). Two of these bats had bands with the inscription CESON.ORG used in the Czech Republic since 2019. The whole ring code was detected…
