Problems of biotic and landscape diversity conservation in the Ukrainian Carpathians highlands

Introduction. The highlands of the Ukrainian Carpathians belong to the territories with the highest concentration of rare species and coenotic diversity in Ukraine. Due to highland ecosystem transformation, a large number of populations and communities of rare species are under the threat of degradation and elimination. Climate change. At present, effective growth and development of plants begins 2–3 weeks earlier compared to the 1980–90s. Sharp seasonal distribution of precipitation causes negative changes in the highland water-body hydrology regime affecting freshwater populations of plankton crustaceans and amphibians. Demutative successions. During the first 10–20 years of the succession its influence on the structure and vitality of the majority of rare species populations is mostly positive, but 30–40 year-long demutations usually cause negative dynamics. Overgro­wing results in the simplification of spatial structure and fragmentation, as well as decreasing of population density, disappearing of rare species from the community structure. Active protection measures should be locally implemented in protected territories: traditional type of grazing, mowing, and shrub or tree cutting in the cases of protection of extremely rare phytocoenoses and populations. Anthropogenic impact. Intensive recreation pressure causes digressive changes in numerous communities, which are located along the popular tourist paths to the glacial lakes, mountain summits etc. Unfortunately, the systematic violation of the protection regime in the highland zone of the Ukrainian Carpathians is obvious nowadays. Gathering medicinal and ornamental species poses a serious threat. Uncontrolled increase in the number of recreants in the highland areas for the last 5 years has destroyed its aquatic ecosystems more than in the previous 30–40 years. Usage of vehicles for recreation purposes (4×4, quads and motorcycles) refers to significant destructive factors for highland ecosystems. Protection measures. Population conservation and revival of communities is usually possible under the condition of moderate and short-term anthropogenic pressure. The visiting regime of the most popular highland sites must be put under control immediately, while mass ascensions must be completely forbidden.

Isolation And Characterization Of 45 SNP Markers In Triplophysa Tenuis

Triplophysa tenuis is an endemic species to China, which mainly distributed in Xinjiang and Gansu province. Effective conservation and management of this species is limited by insufficient molecular markers. In the present study, we reported the isolation and characterization of 45 SNP markers in T. tenuis. The minor allele frequency ranged from 0.046 to 0.500, and the observed and expected heterozygosities ranged from 0.061 to 0.667 and 0.088 to 0.508, respectively. Polymorphic information content ranged from 0.083 to 0.375. Among these SNPs, three loci showed significant departures from the Hardy–Weinberg equilibrium. The novel polymorphic SNPs will be helpful for the future study on genetic management and population conservation for this species.

Resurrection of the Butterfly-winged Comber, Serranus papilionaceus Valenciennes, 1832 (Teleostei, Serranidae) and its phylogenetic position within genus Serranus

The family Serranidae is represented by 92 genera and 579 valid species, with the genus Serranus Cuvier, 1816, containing 30 species. In this study, specimens of Butterfly-winged Comber, Serranus papilionaceus Valenciennes, 1832, were collected from the Canary Islands and compared morphologically and genetically to Painted Comber, Serranus scriba (Linnaeus, 1758), from the Mediterranean Sea. Morphological differences, especially in the colour banding pattern, were corroborated by genetic differences in mitochondrial (COI and ND2) and nuclear (Rhod and PTR) markers. The mitochondrial DNA markers revealed a high level of divergence and no shared haplotypes between the two species (interspecific divergence: COI 4.31%; ND2 8.68%), and a phylogenetic analysis showed that these two species are closely related sister species sharing common ancestry. This study is therefore offering to resurrect S. papilionaceus Valenciennes, 1832 as a valid species increasing the number of eastern Atlantic Serranus species to 11. This should direct new species-specific research, including its population conservation status assessment across its distribution.

DARK FOREST BEE APIS MELLIFERA MELLIFERA L. IN SIBERIA: CURRENT STATE AND WAYS OF POPULATION CONSERVATION

Screening studies of the honey bee in Siberia made it possible to identify the dark forest bee Apis mellifera mellifera populations in the Tomsk region, Krasnoyarsk and Altai territories, and the Altai Republic. A comparative analysis of the genetic diversity of the dark forest bee populations of Siberia, the Urals and Europe, carried out according to the data of the molecular genetic study of the mitochondrial and nuclear genomes, suggests the existence of the Siberian ecotype of the Middle Russian breed. The studied bee colonies are characterized by a high adaptive potential (high degree of "acclimatization") and good economically significant indicators. To preserve the gene pool of the Middle Russian breed of Siberian populations, monitoring studies, ecological and genetic analysis of bee colonies as well as selection and breeding work in the Tomsk bee farm are carried out.

Sexual Dimorphism for Coping Styles Complements Traditional Methods for Sex Determination in a Multivariety Endangered Hen Breed

Sex determination is key to designing endangered poultry population conservation and breeding programs when sex distribution departs from Hardy–Weinberg equilibrium. A total of 112 Utrerana chickens (28 per variety, partridge, black, white, and franciscan) were selected for hatching day sexing. Sex assignation was performed through 10 methods. Three sex assignment criteria comprised criteria found in literature, opposite criteria to that in the literature, and composite criteria combining methods reporting the highest predictive success from the previous ones. This study aims to determine which method combinations may more successfully determine sex across the four varieties of Utrerana endangered hen breed to tailor noninvasive early specific models to determine sex in local chicken populations. Although the explanatory power of the three assignation criteria is equal (75%), assignation criteria 2 resulted to be the most efficient as it correctly assigns males more frequently. Only methods 3 (English method), 5 (general down feathers coloration), 7 (wing fan), and 10 (behavior/coping styles) reported significant differences regardless of the variety, hence, are appropriate for early sexing. Sex confirmation was performed at 1.5 months old. Identifying sex proportions enhances genetic management tasks in endangered populations, complementing more standardized techniques, which may result inefficient given the implicit diversity found in local populations.

Recreational fisheries as a driver of salmonid population conservation

ABSTRACTThe need to monitor and protect biodiversity has never been greater, yet resources are often constrained economically. The ecosystem service paradigm could promote nature conservation while sustaining economic activity and other societal benefits, but most efforts to assess biodiversity-ecosystem service (B-ES) links have focused on diversity measures, with little attention on how species abundance relates to the magnitude of ES provision.Here, we utilised four national scale, multi-decadal, Atlantic salmon (Salmo salar) datasets to investigate links between juvenile density, the abundance of returning adults, and two measures of recreational angling provision: rod catches and angling effort.Recreational rod catches only tracked juvenile density and returning adult numbers in catchments where juvenile and adult numbers were decreasing, implying important early-warning of ES decline. In contrast, angling effort declined consistently through time.Synthesis and applications. These data illustrate i) the difficulty in measuring ES in ways that explicitly relate human resource use to nature conservation, and ii) the need for better quantification of populations at all life stages that determine ES provision, particularly in species where long-distance movements bring exposure to multiple global pressures. We suggest additional opportunities (e.g., monitoring of smolts, eDNA and citizen science initiatives) to facilitate conservation efforts and increase capacity to monitor ecosystem service sustainability.

Improvement of innovation systems in sustainable economic development

This topic of sustainable development and maintenance and development of innovations contributes to the improvement of the ecosystem as a whole. The development and application of global sustainable development goals in the economy of each country contributes to improving the quality of life of the population, conservation of nature, etc. Globalization of economic development contributes to new trends in the future. Within the framework of this direction, various problems related to the SDGs (Sustainable Development Goals) issues are investigated. Sustainable development in general contributes to the accelerated growth of new trends in economic and environmental aspects in many developed and developing countries. The main goal of sustainable development is to create a single basic framework for the unification, renewal and rational use of natural and energy resources, human capital and other energy sources. Innovative technologies contribute to the development of these areas at an accelerated pace, for example, the use of solar energy will help to reduce energy and fuel costs, which will have a significant impact on the health of people and all living organisms.
