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 the area occupied by the animals. The studied region was in the Komárom-Esztergom County, north-western Hungary, where the species was widespread in the middle of the 20th century. It was common in the lowlands, low hilly country and even in suitable habitats in uplands. By 1990 the population had drastically declined, to about 1.5% of the previous levels, and today 99.7% of the population has disappeared with only small, vulnerable populations surviving.

Citizen participation in collect and distribute information increase the role of the citizen involvement in local issues and increasing the benefits of society for the government and the environment. The contribution of citizens can be useful in helping to deal with environment problems and assist certain parties in meeting data needs, this is commonly referred to as citizen science. In its development, citizen science involvement in providing information began to involve social media as a platform for sharing information. In this study we try to explore citizen science of Indonesia, we conduct case study exploring how citizen in Indonesia used social media such as Twitter in response to one of the country’s worst disaster in 2018 namely Lombok Earthquake. By analyzing these user generate message we may know what the response of Indonesian citizen during event and understand more about citizen science in Indonesia through social media including its role and contribution. The information also may assist local communities in obtaining up-to-date information, providing assistance according to needs of the populace and use to manage and plan disaster relief both during and after the event.

Beginning in the 20th century, scientific research came to be dominated by a growing class of credentialed, professional scientists who overwhelmingly displaced the learned amateurs of an earlier time. By the end of the century, however, the exclusive realm of professional scientists conducting research was joined, to a degree, by “citizen scientists.” The term originally encompassed non-professionals assisting professional scientists by contributing observations and measurements to ongoing research enterprises. These collaborations were especially common in the environmental sciences, where citizen scientists participated in counting wildlife and measuring environmental conditions. Later, patient groups began to play a more active role in supporting clinical trials and collecting health records from affected individuals.

Abstract Geographic variability in vocalizations has been documented in many mammalian species. We examined to what extent it applies to the alarm calls of the European ground squirrel Spermophilus citellus. We recorded the calls of 82 adult individuals from 5 natural colonies in the Czech Republic and 24 adult individuals from an artificial seminatural colony located in a Czech zoo. The founders of this colony originated from 4 different natural colonies in the Czech Republic. Our results showed that there are hardly any differences in the acoustic structure of the alarm calls between male and female European ground squirrels. Discriminant function analysis showed the highest degree of discriminability for the most isolated sites (54–74% of individuals classified correctly), whereas the lowest degree of discriminability was found for 2 interconnected colonies (38–40% individuals classified correctly). Individuals from the artificial seminatural colony were often classified correctly to this colony (58% classified correctly); however, the precision of the classification was comparatively relatively low, that is, many individuals from other colonies were incorrectly classified into this seminatural colony. This likely corresponds to the different origins of its founders. These findings indicate that there is a rather substantial geographic variability in the alarm calls of the European ground squirrel, and our study highlights its possible impact on conservation measures such as establishing artificial colonies or reintroductions.

Preserved dialectal features and the Polish influence in old believers' dialect on the example of a representative of the older generation in the Augustów regionPolish Old Believers constitute a bilingual ethno-cultural minority.Their bilingualism has developed especially in the 20th century, and since then it has been modified under the influence of Polish language. On the one hand, there are Polish borrowings, insertions and loan-translations in Russian Old Believers’ dialect. On the other hand, the Old Believers have preserved many dialectal features from their region of origin – Pskov region in north-Western Russia. The author attempts to reveal, how many and which Pskov language features are still present in the Old Believers’ dialect. The analysis is basing on an idiolect of a representative of the old generation of the community of our interest.  Сохраненные диалектные черты и польское влияние в русском говоре представителя старшего поколения старообрядцев августовского регионаПольские старообрядцы составляют этнокультурное меньшинство. Их билингвизм стал развиваться начиная с ХХ столетия, и с тех пор их русский диалект подвергался особосильномувлиянию польского языка. С одной стороны, в старообрядческом говоре наблюдаются польские заимствования, вставки и кальки. С другой стороны, старообрядцы сохранили многие диалектные средневеликорусские черты. Данная статья является попыткой выяснить, какие черты диалектов из окрестностей Великих Лук, Пскова и Новгорода до сих пор существуют в говоре старообрядцев. Анализ опирается на идиолект представителя старшего поколения исследуемой общины.

The russet ground squirrel (Spermophilus major ) is known in the literature as a numerous widespread ground squirrel species. In recent decades, a decline in its abundance was found in some parts of its range. We have assessed the condition of this species in most parts of its distribution area based on our observations and interviews with local people. Spatial, landscape and vegetation cover parameters of S. major settlements have been studied. The research results showed a decline in the number, disappearance of settlements and a decrease in suitable habitats for this species. Small and medium-sized settlements with relatively low density of burrows, associated with low grass meadow communities typical for pastures and cattle grazing, prevail among the found settlements. One of the main factors for the decline in the number and disappearance of settlements of russet ground squirrel is, apparently, a decrease of pasture cattle grazing intensity. The continuing trend of degradation of pasture ecosystems may pose a threat to the existence of this species.
