Bibliography on birds of prey and owls in Slovakia. Part 5. General references and supplements to previous parts

Abstract

The aim of the bibliography is to provide a list of publications on the raptors and owls of Slovakia and of Slovak authors including articles dealing with various organisational issues. The previous parts, which focused on genera from the orders Accipitrifromes, Falconiformes and Strigiformes, are now followed by a fifth part focusing on the raptor and owl species mentioned in various wider associations in the individualarticles. The species, objective and author indexes and the list of periodicals enable better overview

Digestive enzymes in Rhinolophus euryale (Rhinolophidae, Chiroptera) are active also during hibernation

Abstract

During the winter, bats use hibernation as a means of surviving the period of low prey offer. However, the Mediterranean horseshoe bat (Rhinolophus euryale) arouses from torpor quite frequently. Based on the actual climatic conditions, it can profit from occasional foraging oportunities, when they occur. We analysed faeces collected on four nights during the period from November 2012 to February 2013 from the Domica-Baradla cave system (Slovakia and Hungary). In mid-November, the largest proportion of faecal contents were from Lepidoptera. Later on, the proportion of non-consumptive mass in the faeces increased and prey remnants disappeared. We analysed the activity of digestive enzymes (amylase, chitobiase, endochitinase and glukosaminidase) in faeces. The activity of these enzymes was detected in fresh faeces throughout the whole winter. The faecal activity of the chitinases was relatively stable during the monitored period, whilst the activity of amylase was highest during late November and December. Some level of active digestive enzymes during the winter could be an adaptation to occasional winter foraging.

Go to the city: urban invasions of four pipistrelle bat species in eastern Slovakia

Abstract

Until now, late summer or autumn invasions into inhabited building have been regarded as phenomenon typical for the common pipistrelle, pipistrellus pipistrellus, exclusively. During the investigation of this phenomenon in the city of Košice (eastern Slovakia), we discovered that it was not always entirely specific for this species. During the period 2016–2018, we recorded 3 events out of 35 invasions, where small groups of common pipistrelles that invaded into inhabited buildings were also accompanied by individuals of two con-generic bat species, pipistrellus pygmaeus and pipistrellus kuhlii. Cryptic species p. pipistrellus and p. pygmaeus were determined by genetic test. In addition, in 2019, we recorded the first winter occurrence of another pipistrelle species, pipistrellus nathusii, in this urban environment. We conclude that areas of frequent invasive behaviour of p. pipistrellus may be sometimes associated with concomitant occurrence of other related species that share common thermal or foraging niche and such behaviour could be evidence of their urbanisation tendencies.
