Dealing with viewers’ complaints: Role, visibility and transparency of PSB Ombudsmen in ten European countries
2017
The article shows the results of a comparative analysis of the complaints management mechanisms offered by ten European Public Service Broadcasting (PSB) systems on their corporate websites. Using a qualitative methodology, it maps the procedures and evaluates the visibility, transparency and dissemination of results. The findings show, firstly, great diversity in terms of responsible election and management, despite the converging media governance. Also noteworthy is the margin of substantial improvement in the transparency and dissemination possibilities, specially relating to the interaction offered by the digital environment. Among the ten public corporations analysed, the BBC is the be…
Semi-natural habitats in boreal Europe: a rise of a social-ecological research agenda
2021
The European continent contains substantial areas of semi-natural habitats, mostly grasslands, which are among the most endangered habitats in Europe. Their continued existence depends on some form of human activity, for either production or conservation purposes, or both. We examined the share of semi-natural grasslands within the general grassland areas in boreal Europe. We reviewed research literature across the region to compile evidence on semi-natural grasslands and other semi-natural habitats, such as wooded pastures, in respect to a range of topics such as ecology, land-use change, socioeconomics, and production. We also explored drivers of the research agenda and outlined future re…
Conservation status of the Italian flora under the 92/43/EEC ‘Habitats’ Directive
2021
The results of the 4th National Report for the Italian flora under the 92/43/EEC ‘Habitats’ Directive are presented. The outcomes showed a general negative conservation status for plant species, with the worst situation being in the Mediterranean bioregion. At the National level, significant monitoring and conservation activities are required.
The legacy of human use in Amazonian palm communities along environmental and accessibility gradients
2023
Aim: Palms are iconic and dominant elements of neotropical forests. In the Amazon region, palms have been used and managed by humans for food, material, medicine and other purposes for millennia. It is, however, debated to what extent the structure of modern palm communities reflects long-term human modification. Here, we investigate the complex interplay of ecological and societal factors that influence the distributions of both human-used and non-used palms in western Amazonia. Location: Amazonia. Time period: Present. Major taxa studied: Palms (Arecaceae). Methods: We used Bayesian hierarchical joint species distribution models to predict the distributions and environmental niche dimensi…

The paper presents new faunistic data on the occurrence of true-bugs Heteroptera in south-eastern Poland. Localities were scattered in 25 UTM squares in five zoogeographical regions: Małopolska Upland, Świętokrzyskie Mts, Western Beskidy Mts, Eastern Beskidy Mts and Bieszczady Mts. In total we present the data concerning 129 true-bug species, including Elasmucha grisea (listed for the first time from Świętokrzyskie Mts), Heterocordylus leptocerus, Polymerus nigrita, Raglius alboacuminatus, Scolopostethus pictus, Chartoscirta cincta cincta and Physatocheila smreczynskii (first records from Małopolska Upland), Nabis flavomarginatus, N. limbatus, Peribalus strictus, Coptosoma scutellatum and S…
Stilt bugs (Hemiptera: Heteroptera: Berytidae) of Poland: check-list, distribution, bionomics
2019
W Polsce pluskwiaki różnoskrzydłe z rodziny smukleńcowatych (Berytidae) reprezentowane są przez dziewięć gatunków sklasyfikowanych w czterech rodzajach: Neides tipularius, Berytinus clavipes, B. hirticornis, B. minor, B. crassipes, B. signoreti, Gampsocoris culicinus, G. punctipes i Metatropis rufescens. Niniejsze opracowanie, poza nowymi stanowiskami, podsumowuje wszystkie dane na temat występowania przedstawicieli Berytidae na terenie naszego kraju. Dodatkowo podano podstawowe informacje dotyczące biologii wymienionych gatunków (preferencje wilgotnościowe, termiczne, troficzne oraz ilość generacji w roku). Berytinus montivagus został wyłączony z krajowej fauny, jednak jego występowanie w …
In-depth characterization of denitrifier communities across different soil ecosystems in the tundra
2022
Abstract Background In contrast to earlier assumptions, there is now mounting evidence for the role of tundra soils as important sources of the greenhouse gas nitrous oxide (N2O). However, the microorganisms involved in the cycling of N2O in this system remain largely uncharacterized. Since tundra soils are variable sources and sinks of N2O, we aimed at investigating differences in community structure across different soil ecosystems in the tundra. Results We analysed 1.4 Tb of metagenomic data from soils in northern Finland covering a range of ecosystems from dry upland soils to water-logged fens and obtained 796 manually binned and curated metagenome-assembled genomes (MAGs). We then sear…

More nature in the city
2020
According to projects and practices that the Italian botanists and ecologists are carrying out for bringing “more nature in the city”, new insights for a factual integration between ecological perspectives and more consolidated aesthetic and agronomic approaches to the sustainable planning and management of urban green areas are provided.
