The diet of three owl species was analysed in 32 sites localised in the Masovian Landscape Park and its outskirts to determine the structure of small mammal communities. Study was done in the years 1993–2016, 5,728 vertebrate prey (including 4,001 mammals) were collected. Five species of soricomorphs, six bats, 14 rodents and one species of Carnivora were found. Among mammals, Myodes glareolus had the greatest share in the diet of Strix aluco. Tyto alba most frequently caught Microtus arvalis and Sorex araneus, while Asio otus – M. arvalis and M. oeconomus. Those prey, together with Apodemus flavicollis and A. agrarius, dominated in small mammal communities. One site of Crocidura leucodon was found on the western edge of its range in Poland. The share of bats in the diet of S. aluco was small (0.5% of mammals), Plecotus auritus was most frequent. Muscardinus avellanarius was found in forests of the southern part of the Masovian Landscape Park. It was relatively often caught by S. aluco in favourable habitats. Shares of M. oeconomus, M. agrestis and M. avellanarius in the diet of owls were significantly higher in southern part of the study area remote from Warsaw.

The relative abundance of small mammal species detected from Common Barn-owl pellets reflects the landscape structure and habitat pattern of the owl’s hunting area, but it is also affected by the size of the collected pellet sample and the size of the supposed hunting area. The questions arise: how many pellets should be collected and analyzed as well as how large hunting area should be taken into consideration in order to reach the best correspondence between the owl’s prey composition and the distribution of habitats preferred by small mammals preyed in supposed hunting areas? For this study, we collected 1045 Common Barn-owl pellets in a village in southern Hungary. All detected small mammal species were classified into functional groups (guilds) preferring urban, open, forest and wetland habitats. The proportion of functional groups was compared to the proportion of these habitats around the pellet collection site within circles of one, two, and three km radius. Saturation curves showed that at least 300 pellets or ca. 600 mammalian remains are required for the detection of the 19 small mammal species. The share of small mammals detected in the prey and their functional groups according to their habitat preference showed an increasing consistency with the distribution of real habitats in the potential hunting area of a radius of 3 km around the owl’s breeding or resting place.

The study of the species composition and biotope preferences of small mammals around Kolomak had been carried out for four years (2017–2020). During the study period, 9 species of mouse-like rodents and 3 species of insectivores were found. No Cricetulus migratorius, Terricola subterraneus or Microtus oeconomus were found from the theoretically expected species already known for this area. Around Kolomak, 11 biotopes were investigated, including maple-linden oak forest, agrocenoses, dry and flooded meadows, which are located along the banks of a pond and in a gully-ravine system. The first year of research was in a year of high abundance (2017), and then 9 species were immediately discovered, but species with small abundance, such as Crocidura suaveolens, Sorex minutus, and Micromys minutus, were found in years with a small relative abundance of small mammals. Myodes glareolus, Sylvaemus tauricus and Sylvaemus uralensis are dominant species in the captures. According to the trapping results, 2017 was the year of high relative abundance of small mammals, 2018 was the year of the lowest relative abundance, 2019 and 2020 were years with an average relative abundance. During the study period, 6 species were identified in forest biotopes (Apodemus agrarius, Sylvaemus tauricus, Sylvaemus uralensis, Myodes glareolus, Sorex araneus, and Dryomys nitedula). In ecotones with floodplain biotopes, 8 species were found (Apodemus agrarius, Sylvaemus sylvaticus, Sylvaemus uralensis, Mus musculus, Micromys minutus, Myodes glareolus, and Sorex araneus). Four species (Mus musculus, Sylvaemus sylvaticus, Sylvaemus uralensis, and Microtus levis) were discovered near human settlements. In general, biotopes with the greatest species diversity and number of caught individuals are ecotones of dry and floodplain meadows. In years of high abundance, both species diversity and the number of individuals caught in the oak forest and in ecotones near the pond increased. It should be noted that Myodes glareolus was caught in clear-cuts during the two years (2019-2020) only in the summer of 2020. Earlier, not a single specimen of this species was caught there, although there is a dense weed grass cover in this area and the shrub layer has also grown up in some places, and the clear-cut is surrounded by oak forest.

Το ενδιαίτημα των δέντρων είναι ένα περίπλοκο πλέγμα κορμών, κλαδιών και φυλλώματος, τα οποία καθιστούν την κίνηση και μετακίνηση απαιτητικές. Όμως, τα θηλαστικά έχουν καταφέρει να ανταπεξέλθουν στην πολυπλοκότητά του. Κατά την κίνηση επί των κλαδιών, η αναγκαιότητα για ασφάλεια και σταθερότητα εντείνεται. Επιπρόσθετα, καθώς τα πρώιμα ευθήρια θηλαστικά επιδεικνύουν μετακρανιακό σκελετό που σχετίζεται με τη διαβίωση στα δέντρα, είναι σημαντικό να μελετήσουμε τους συμπεριφορικούς μηχανισμούς που σχετίζονται με την αποδοτική δενδρόβια κίνηση. Ωστόσο, υπάρχει μία γενική έλλειψη ερευνών σε άλλα θηλαστικά και ιδιαίτερα τα πιο μικρόσωμα. Η παρούσα έρευνα χρησιμοποιεί μία πειραματική προσέγγιση προσομοιωμένων δενδρικών συνθηκών, επιχειρώντας να απομονώσει παραμέτρους των υποστρωμάτων και να συγκρίνει το πώς διαφορετικά μικρά θηλαστικά τροποποιούν τον βηματισμό τους για την δενδρόβια κίνηση. Για τους σκοπούς της παρούσας διατριβής εξετάσαμε οκτώ μικρόσωμα θηλαστικά: Acrobates pygmaeus(~12 g), Micromys minutus (~10 g), Apodemus agrarius (~20 g), Apodemus flavicollis (~30 g), Thallomys paedulcus (~70 g), Myodes glareolus (~20 g), Muscardinus avellanarius (~20 g), Glis glis (~130 g). Όλα κινηματογραφήθηκαν επί διαφορετικών διαμετρών υποστρωμάτων (2mm, 5mm, 10mm, 25mm) και κλίσεων (κάθοδος 45°, οριζόντιο, άνοδος 45°) στα 240 καρέ ανά δευτερόλεπτο σε ειδικά σχεδιασμένο τερράριο. Οι αναλύσεις μας αφορούσαν βασικές παραμέτρους βάδισης, όπως η διαγωνιότητα, ο παράγοντας φόρτου, ο δείκτης παράγοντα φόρτου, η ταχύτητα, το μήκος διασκελισμού και η συχνότητα διασκελισμού. Τα περισσότερα από τα εξεταζόμενα μικρά αναρριχητικά θηλαστικά επέλεξαν βάδιση πλευρικής-αλληλουχίας κατά την δενδρόβια κίνηση. Το Acrobates pygmaeus ήταν μια αξιοσημείωτη εξαίρεση, επιδεικνύοντας βάδιση διαγώνιας-αλληλουχίας, σε σύγκλιση με τα πρωτεύοντα. Τα περισσότερα μικρά θηλαστικά μείωσαν την διαγωνιότητα, τις σχετικές φάσεις αιώρησης των άκρων, και την ταχύτητα στα λεπτότερα υποστρώματα, προς αύξηση της σταθερότητας και απρόσκοπτης πλοήγησης. Σε πλατύτερα υποστρώματα, τα περισσότερα μικρά θηλαστικά αύξησαν σημαντικά την ταχύτητα και τις σχετικές φάσεις αιώρησης, και την χρήση ασύμμετρης βάδισης, με σκοπό ταχείες κινήσεις, αποφυγή εμποδίων και ενεργειακή βελτιστοποίηση, και πιθανώς μείωση έκθεσης στους θηρευτές. Η επίδραση της κλίσης στις παραμέτρους βάδισης ήταν πολύ ανόμοια ανάμεσα στα εξεταζόμενα είδη, υπονοώντας ότι πιθανώς να υπάρχει κάποια ενδογενής περιπλοκότητα, και διάφοροι μηχανισμοί οι οποίοι να επιδρούν σε αυτή. Σε σχέση με την ρύθμιση της ταχύτητας, σχεδόν όλα τα μικρά θηλαστικά αύξησαν την ταχύτητα κυρίως μέσω της συχνότητας διασκελισμού, παρά μέσω του μήκους διασκελισμού, το οποίο επίσης προωθεί την δενδρόβια ασφάλεια, μειώνοντας τις σωματικές ταλαντώσεις. Επιπροσθέτως, κάποιες από τις εξεταζόμενες παραμέτρους, όπως ο παράγοντας φόρτου και η συχνότητα διασκελισμού, προέβλεψαν με συνέπεια τον βαθμό δενδροδιαβίωσης. Εν κατακλείδι, παρά κάποιες περιορισμένες ανομοιότητες, τα μικρά δενδρόβια και αναρριχητικά θηλαστικά επιδεικνύουν συμπεριφορές που εν τέλει συνεισφέρουν στην επιτυχημένη εκμετάλλευση του ενδιαιτήματος των δέντρων. Το σωματικό μέγεθος και οι μορφολογικές ομοιότητες μεταξύ σύγχρονων δενδρόβιων/αναρριχώμενων μικρών θηλαστικών και των πρώιμων προγόνων των ευθηρίων (π.χ. Eomaia kai Juramaia) υπονοούν ότι αυτές οι πρώιμες μορφές θα συμπεριφέρονταν με παρόμοιους τρόπους, επιδεικνύοντας βάδιση πλευρικής-αλληλουχίας, σχετικά υψηλούς παράγοντες φόρτου, και αύξηση της ταχύτητας με αύξηση της συχνότητας διασκελισμού. Αυτές οι προσαρμογές, οι οποίες θα βοηθούσαν στην αποδοτική χρήση τόσο εδαφικών όσο και δενδρικών υποστρωμάτων, πολύ πιθανόν να συνεισέφεραν στην επιτυχή επικράτησή τους και στην ακόλουθη ακτινωτή διαπορά τους.

AbstractThe diets of small mammals in different hemiboreal spruce-dominated, oak-dominated and mixed forests in western part of Lithuania were studied by examination of fungal spores in fresh fecal pellets of caught animals. In the diets of mice (Apodemus spp.), bank voles (Myodes glareolus), and common and pygmy shrews (Sorex araneus and S. minutus), 22 different fungal taxa were identified, 15 of which were hypogeous fungi. The sporocarp abundance and the spores in fecal samples of Elaphomyces fungi prevailed in study area during this investigation. Although most of the captured individuals consumed fungi, the consumption varied among small mammal species. The data show that the fungi were more frequent and taxonomically diverse in Myodes glareolus than in Apodemus spp. diets. The study provided evidence that the fungal component in the diets of insectivorous Sorex species is more diverse than previously known. The availability of sporocarps and the fungal component in the diets of small mammals showed seasonal effects. Annual hypogeous and epigeous sporocarp abundances did not vary significantly across forest types. The significant difference in mycophagy was observed across all forest cover types, with the greatest fungal diversity in fecal samples collected in mixed coniferous-deciduous tree stands.

The article considers the issues of carriage by small mammals of dangerous zoonotic diseases: leptospirosis, tularemia, hantaviruses. Data on the detection of antigens to pathogens in the districts of the Kaluga region are presented. As you know, small mammals are the main link in maintaining zoonotic natural focal diseases. The larval phases of ixodic ticks, mosquitoes and other parasitic arthropods prefer to feed on the blood of mouse rodents, which contributes to the spread of vector-borne infections and infestations. The following species of mouse rodents are found in the Kaluga Region: small forest mouse (Apodemus uralensis), gray vole, red vole (Myodes glareolus), field mouse (Apodemus agrarius), gray rat (Rattus norvegicus), and house mouse (Mus musculus). In natural biotopes, field species prevail in number: field mouse, gray vole, red vole. In the Kaluga region, antigens for tularemia, hantaviruses, and leptospirosis were found in small mammals in 4.9–9.4% of the studied animals on average per year. Of particular concern are the city of Kaluga, Borovsky, Babyninsky, Yukhnovsky, Ulyanovsk, Medynsky, Maloyaroslavetsky, Meshchovsky, Peremyshlsky, Kozelsky, Dzerzhinsky and Ulyanovsk districts. The data obtained indicate the stationarity of these diseases in the territory of the Kaluga region.
