Research interests: behavioural ecology and reproductive strategies of birds, orthopterans; foraging and feeding ecology of birds, relationships between birds, insects and plants; life decisions and survival strategies in selected endangered species of birds, orthopterans and bats; IUCN Red List of European Orthoptera and principles for species selection in Anex II of Habitats Directive. Applied research is focused on suggestions of rules and principles in habitats management for particular study species and assemblages.

Salvage and sanitation loggings (hereafter salvage logging) are usually practiced following such disturbance events and the generated deadwood is then extracted from the forest. Those practices affect a broad array of species, including fungi, lichens, invertebrates, and vertebrates that make use of deadwood either as habitat, food resource, foraging substrate, or as shelter. Woodpeckers, being a key group of forest birds dependent on deadwood, can be affected by salvage logging in two ways: (1) a reduction in the availability of food (i.e. removal of deadwood along with the saproxylic and predatory invertebrates that usually colonize dead or dying trees following forest disturbances) and (2) a decrease in potential nest sites due to the removal of dead trees. Therefore, we assessed the global effects of salvage logging on woodpecker abundance and reproduction by conducting a meta-analysis of published and unpublished data. We focused on comparing woodpeckers’ responses to forest disturbance in salvage-logged and unlogged sites. We considered different types of responses found in the literature, including abundance, occurrence, nest density, and breeding success. When analyzing the responses of woodpeckers, we also accounted for the potential effects of tree density, time since logging, elevation, latitude, and the continent. Recent Findings We found that both numbers and reproduction of woodpeckers were affected by salvage logging following a disturbance event. Apart from salvage logging, woodpecker responses were not significantly related to any other variables. This highlights that salvage logging can pose a substantial threat to woodpecker assemblages as well as secondary cavity-users dependent on them. Summary Salvage logging and related practices that affect deadwood availability should be carefully planned and preferably avoided entirely in areas important for woodpecker conservation.

The nestling diet composition and its foraging ecology are little known in the entire range. Therefore, we studied the composition of the nestlings’ food and some aspects of its foraging ecology by photos from the shelter, in a population on abandoned agricultural land (17 ha) in Western Slovakia near Piešťany town (48,55098° N, 17,805612° E, 150 m asl.) in April–July 2017–2022. Analyzing 177 photos/feedings of young (1–12 days old) by a male and a female in 9 nests, was found a total of 361 prey items (2.7% of them unidentified). The food consisted of invertebrates from 12 orders, 33 families, and approximately 86 species. Spiders (Araneida, 19.4%), crickets and grasshoppers (Orthoptera, 18.6%), and moths (Lepidoptera) and dipterans (Diptera) with the same proportion 15.2%, belonged to the eudominant prey groups. Among the dominant and frequent species were, e. g., the aposematically coloured spider Argiope bruenichii, the mayfly Ephemera danica, the bush-crickets Leptophyes albovittata, Bicolorana bicolor, from other taxa there were significantly represented Noctuidae and Geometridae caterpillars, cicadas (Cicadellidae) and flies from the suborder Nematocera.

The nestling diet composition and its foraging ecology are little known in the entire range. Therefore, we studied the composition of the nestlings’ food and some aspects of its foraging ecology by photos from the shelter, in a population on abandoned agricultural land (17 ha) in Western Slovakia near Piešťany town (48,55098° N, 17,805612° E, 150 m asl.) in April–July 2017–2022. Analyzing 177 photos/feedings of young (1–12 days old) by a male and a female in 9 nests, was found a total of 361 prey items (2.7% of them unidentified). The food consisted of invertebrates from 12 orders, 33 families, and approximately 86 species.

Within the bush-cricket family we could identify the species of genera Tettigonia, Decticus, Platycleis, Isophya and Metrioptera. The species of genera Calliptamus, Stenobothrus and Locusta belonged among the locust species identified in the food. Birds and mammals were found in pellets only occasionally. The prey composition was rather similar at both studied sites, while locusts (Acrididae) were more abundant at the Jorgucat site and bush-crickets (Tettigonioidea) at the Mollas site in the same time. Prey groups Scarabeidae beetles and other beetles (Coleoptera other) were more abundant and frequent at Mollas than at Jorgucat, and spiders were more frequent at Jorgucat. These results suggest that the high abundance of orthopterans and beetles in the food supply in certain localities is the main reason for selection and stable occupancy of these massive communal roosting sites by lesser kestrels in Albania. |
