One of the greatest challenges of the 21st century is the conservation of biodiversity. Human-influenced landscapes often negatively affect pollinator health and diversity at various scales resulting in limiting pollination services, which is crucial for our food security and the maintenance of biodiversity. SPHERE is an innovative Master course th...

Burning of fossil fuels, application of fertilisers, and livestock farming have greatly increased emissions of reactive nitrogen (N). The consequent increase in atmospheric deposition of N compounds has compromised air, soil and water quality, ecosystems, and human health and wellbeing. Sulphate aerosols also affect climate dynamics by scattering s...

Invasions of species into ecosystems cause their transformation and, in certain cases, their degradation. The study was carried out to determine the extent of the invasion of Cydalima perspectalis (Walker, 1859). For this purpose, the following aspects were analyzed: distribution of the species in different countries of the worldі, history of invas...

Losses of Western honey bee colonies (Apis mellifera L.) represent a globally significant phenomenon with profound ecological and economic implications, yet the underlying causes remain a subject of ongoing investigation (Insolia et al., 2022). This study aimed to evaluate colony losses following the 2022–2023 wintering season in Ukraine in the con...

Since the beginning of the 21st century, the increase of honey bee colony losses (Apis mellifera L.), especially in Europe, Asia and North America, has prompted the search for standardized large-scale studies to avoid catastrophic consequences for both ecosystems and the world economy. This paper presents the results of research on honey bee colony...

The 30,491 beekeepers outside New Zealand reported 4.5% of colonies with unsolvable q...

Rural landscapes face multiple challenges, but they can be attractive for developing nature-based tourism. Encouraging place-based participatory governance in local communities represents a relevant transdisciplinary landscape approach. In this study, we map (1) rural and touristic challenges and (2) coping strategies in peripheral–rural municipali...

Anthropogenic landscape transformations have promoted the provision of ecosystem services (ES) at the expense of other ES, biodiversity, and human well-being. We analysed the transformation portfolios of ES provisions, the costs of transformation, and the rivalry between ES categories and biodiversity conservation during the pre-communist and commu...

The western honey bee (Apis mellifera L., Hymenoptera: Apidae) is a species of invaluable economic, agricultural and environmental importance. However, over the last decades, most countries around the world have faced serious problems of bee health and surviving. The purpose of this study was to analyze the success of A. mellifera colonies winterin...

The work is devoted to the study of the insect pollination influence on the qualitative and qualitative indica-tors of the 14 high-productive autofertile Helianthus annuus L. hybrids by five producers, grown under conditions of the Prut-Dniester interfluve. The following components of the oilseed sunflower crop structure were analyzed: dry weight o...

Sunflower oil importance, cultivation history, floral anatomy, flowering physiology, evolutionary adaptations of sunflower for insect cross-pollination and behavior of honey bees at its visiting are described. This plant has long, interesting and confusing history with rediscovering its seed oility and repatriation in form of big headed oil cultiva...

Physical and chemical quality indicators of 65 polyfloral honey samples from three administrative districts of Chernivtsi region in South Western Ukraine were studied. The chosen administrative districts were Putyla (representing the ‘Traditional villages’ stratum), Storozhynets (the ‘Intermediate’ stratum) and Khotyn (the ‘Intensive agriculture’ s...

Arthropods are reported to serve as vectors of transmission of pathogenic microorganisms to humans, animals, and the environment. The aims of our study were (i) to identify the external bacteriota of spiders inhabiting a chicken farm and slaughterhouse and (ii) to detect antimicrobial resistance of the isolates. In total, 102 spiders of 14 species...

Beekeepers have various options to control the parasitic mite Varroa destructor in honey bee colonies, but no empirical data are available on the methods they apply in practice. We surveyed 28,409 beekeepers maintaining 507,641 colonies in 30 European countries concerning Varroa control methods. The set of 19 different Varroa diagnosis and control...

Expectations of what forests and woodlands should provide vary among locations, stakeholder groups, and over time. Developing multifunctional forests requires understanding of the dynamic roles of traditions and cultural legacies in social-ecological systems at multiple levels and scales. Implementing policies about multifunctional forests requires...

Сучасні дослідження свідчать про виникнення глобальної кризи запилення щодо сільськогосподарських і природних екосистем. Значну частину їжі людина одержує саме з ентомофільних рослин. Тому збереження й захист антофільних видів комах як основних «агентів» запилення наразі актуальна проблема. В Україні родина Rosaceae належить до провідних за кількіс...

Introduction. Sunflower is one of the most profitable high yielding technical crops in Ukraine. Insect pollination plays a vital role in determining its productivity. Nowadays a wide range of the new hybrides with high self-fertility rate are supposed to mature seeds in the absence of honey bees and other pollinators. In order to evaluate the effec...

The allelopathic potential of classical energy crops (Panicum virgatum L., Sorghum saccharatum (L.) Moench, hybrids ‘Zubr’ and ‘Medovyi’) was studied by the energy of germination of biotesters’ seeds and their biometric parameters, as well as the selection of sensitive biotesters and test traits. Secale cereale L. and Raphanus sativus L. var. radic...

Exploitation of natural forests forms expanding frontiers. Simultaneously, protected area frontiers aim at maintaining functional habitat networks. To assess net effects of these frontiers, we examined 16 case study areas on five continents. We (1) mapped protected area instruments, (2) assessed their effectiveness, (3) mapped policy implementation...

Energy cropping has positive effect only if considering and mitigating potential biodiversity loss in agroecosystems. While investigating ground-dwelling animal assemblages in experimental fields of miscanthus and switchgrass in comparison with a legume-grass mixture and an abandoned field, we found low abundance and taxon diversity of the energy c...

Objectives Stressing the need for SES analyses, we explore beekeepers’ perceived factors affecting bees and beekeeping, test the hypothesis that honey bee c...

Achieving sustainable development as an inclusive societal process in rural landscapes, and sustainability in terms of functional green infrastructures for biodiversity conservation and ecosystem services, are wicked challenges. Competing claims from various sectors call for evidence-based adaptive collaborative governance. Leveraging such approach...

Context Maintaining functional green infrastructures (GIs) require evidence-based knowledge about historic and current states and trends of representative land cover types. Objectives We address: (1) the long-term loss and transformation of potential natural forest vegetation; (2) the effects of site productivity on permanent forest loss and emerg...

Invasions of species into ecosystems lead to their transformation and in some cases to degradation. The spanish slug Arion lusitanicus Mabille, 1868 (Mollusca: Gastropoda: Stylommatophora: Arionidae) has been spread actively in Europe including some regions of Ukraine recently. This is a dangerous invasive species that causes significant damage to...
