Another alien bug in Europe: the first case of transcontinental introduction <br />of the Asiatic burrower bug Macroscytus subaeneus (Dallas, 1…
2019
The Oriental burrower bug Macroscytus subaeneus (Dallas, 1851) (Hemiptera: Heteroptera: Cydnidae: Cydninae), presently known only from single localities in Flores (Indonesia), the Philippines and Thailand, is recorded from the United Kingdom (hereafter U.K.). A single female specimen was collected on the semi-rural edge of Bath city by a Starling (Sturnus vulgaris L.) and taken to its nest from which it was retrieved during 2015. The specimen is illustrated and its diagnostic characters are provided. We hypothesize that this specimen could have been imported with a shipping container from Thailand.
Decomposition of nest material in tree holes and nest-boxes occupied by European Starlings Sturnus vulgaris: an experimental study
2017
Numerous bird species depend on the availability of tree cavities, and most non-excavators fill their cavities with considerable amounts of nest material. If not removed, this material can accumulate and render cavities unusable, as recorded in some nest-box studies. Data from earlier studies of tree cavities, however, showed that nest material can decrease mostly due to in situ decomposition, but the relative difference between nest decomposition in tree holes and nest-boxes is still unknown. We undertook parallel studies of decay in tree holes and nest-boxes used by European Starlings Sturnus vulgaris in oak-hornbeam stands (SW Poland). We inserted into its tree holes and nest-boxes litte…
Variation in clutch size in relation to nest size in birds
2014
© 2014 The Authors. Nests are structures built to support and protect eggs and/or offspring from predators, parasites, and adverse weather conditions. Nests are mainly constructed prior to egg laying, meaning that parent birds must make decisions about nest site choice and nest building behavior before the start of egg-laying. Parent birds should be selected to choose nest sites and to build optimally sized nests, yet our current understanding of clutch size-nest size relationships is limited to small-scale studies performed over short time periods. Here, we quantified the relationship between clutch size and nest size, using an exhaustive database of 116 slope estimates based on 17,472 nes…
Data from: Plant – herbivorous beetle networks: molecular characterization of trophic ecology within a threatened steppic environment
2015
DNA barcoding facilitates many evolutionary and ecological studies, including the examination of the dietary diversity of herbivores. In this study, we present a survey of ecological associations between herbivorous beetles and host plants from seriously threatened European steppic grasslands. We determined host plants for the majority (65%) of steppic leaf beetles (55 species) and weevils (59) known from central Europe using two barcodes (trnL and rbcL) and two sequencing strategies (Sanger for mono/oligophagous species and Illumina for polyphagous taxa). To better understand the ecological associations between steppic beetles and their host plants, we tested the hypothesis that leaf beetl…
Nesting of the Spotless Starling, <em>Sturnus unicolor</em>, on the island of Favignana (Aegadian Islands, Sicily)
2021
The presence of the Spotless Starling in Sicily was reported for the first time at the beginning of the XIX century, although the first nests for the province of Trapani are reported almost at the end of the XX century. As a breeder, the Spotless Starling remained absent from all the circumsicilian islands until the first report for the island of Pantelleria, in 2012. In 2020, the nest of Spotless Starling was observed on the island of Favignana, within a hole on an antenna. The couple fed the chicks with Ligia italica crustacean isopod of the family Ligiidae. The nesting on the island of Favignana confirms the continuous expansion of the species in Sicily.

Mājas strazda Sturnus vulgaris pavasara atlidošanas fenoloģijas izmaiņas Ziemeļaustrumeiropā laika posmā no 1922. līdz 2017. gadam
2021
Pētījumā analizētas mājas strazda Sturnus vulgaris pavasara atlidošanas fenoloģijas pārmaiņas Ziemeļaustrumeiropā laika periodā no 1922. līdz 2017. g. un to saistība ar izmaiņām meteoroloģiskā pavasara iestāšanās laikā. Mājas strazdu pavasara atlidošanas laiks būtiski korelē ar pavasara iestāšanos, un periodā no 1922. līdz 2017. g. tas ir kļuvis vidēji par 12 dienām agrāks. Tomēr pārmaiņas pavasara iestāšanās laikā notiek vēl straujāk – tam, pētījumā aplūkotajā periodā, kļūstot vidēji par 27 dienām agrākam. Tādējādi apstiprinās izvirzītā hipotēze, ka gaisa temperatūras pieauguma ietekmē, mājas strazdu pavasara atlidošanas fenoloģija Ziemeļaustrumeiropā pēdējā gadsimta laikā ir kļuvusi būtis…
Ziemeļeiropā ligzdojošo mājas strazdu (Sturnus vulgaris) migrācijas stratēģijas un ziemošanas vietu pārmaiņas pēdējā gadsimta laikā
2022
Siltumnīcas efekta gāzu koncentrācijas palielināšanās atmosfērā ir izraisījusi klimata pasiltināšanos, kas ir ietekmējusi procesus dabā. Izmaiņas ir notikušas arī putnu migrācijās un daudzas tuvo migrantu putnu sugas veic aizvien īsākus migrāciju attālumus. Šajā pētījumā tiek noskaidrots vai un kā vēsturiski izmainās attālums starp tuvā migranta mājas strazda ziemošanas un ligzdošanas vietām klimata izmaiņu ietekmē Ziemeļeiropā. Pētījumā izmantota no EURING datubāzes atlasīta datu kopa par Ziemeļeiropā ligzdošanas laikā apgredzenoto mājas strazdu atradumiem ziemošanas laikā visā Eiropā no 1926. līdz 2019. gadam. Baltijas valstu, Skandināvijas valstu un Polijas mājas strazdu populācijām pēdē…
