Selection of URBANIZATION Indicator Species Through Naturalized Plant Distribution Analysis

Indicator species approaches are widely used in conservation as a shortcut to measuring attributes of species and ecosystems. A variety of indicator species concepts are in use and are applicable to a range of situations. Indicator species are increasingly being used in environmental reporting to evaluate trends in environmental attributes quantitatively. We use the most recent State of the Environment report from New Zealand as a case study to evaluate: (1) how indicator species concepts are being applied to environmental reporting and (2) the selection of individual species as indicators. At present indicator species used in environmental reporting in New Zealand reflect biases in national monitoring data towards forest-dwelling, terrestrial vertebrates that are vulnerable to predation by introduced mammals. Scientific literature generally supports links between selected taxa and the aspect of ecosystem health they are purported to indicate, but their roles as long-term indicators of environmental health have yet to be evaluated. A primary goal of State of the Environment reporting is to set a benchmark against which environmental outcomes can be monitored over time; thus it is recognized that taxa reported should represent a broader range of environmental attributes. However, selection of taxa for environmental reporting is severely constrained by limited national species monitoring data. A strategic approach to national measurement, storage and analysis of long-term monitoring data is required to support selection of representative species for environmental reporting. We support current initiatives to select taxa for future measurement and reporting in an objective, transparent manner and recommend that they encompass representation of: (1) taxonomic diversity, (2) ecosystem types, (3) key environmental pressures and (4) threat status.

Part of a recently advocated method of sustainable forest development employs indicator species as fine filters to assess changes within ecosystems and landscapes. We used a series of criteria based on biology, sampling methods, and legal or particular status to select vertebrate indicator species for the province of Ontario. The criteria for selection were applied in a hierarchical manner, with species ecology given primary importance, followed by sampling considerations, and status criteria. The latter represented certain societal weightings and political or featured management concerns. Species fitting the selection criteria were placed in a four-dimensional matrix (with axes: broad habitat type, age class, trophic level, and spatial scale), and species were then chosen from among the matrix cells. The exercise reduced the total vertebrate species in two forest biomes (Boreal and Great-Lakes St. Lawrence) to a relative few, from which the final choices were made primarily based on expert opinion. In Ontario, the species selected as indicators of biological diversity will be used to test the underlying general hypothesis that forest management has no effect on species richness and species abundance, or the distribution of species in time and space.

Objective: To analyze the SARS-CoV-2 genomic epidemiology in the Balearic Islands, a unique setting in which the course of the pandemic has been influenced by a complex interplay between insularity, severe social restrictions and tourism travels.Methods: Since the onset of the pandemic, more than 2,700 SARS-CoV-2 positive respiratory samples have been randomly selected and sequenced in the Balearic Islands. Genetic diversity of circulating variants was assessed by lineage assignment of consensus whole genome sequences with PANGOLIN and investigation of additional spike mutations.Results: Consensus sequences were assigned to 46 different PANGO lineages and 75% of genomes were classified within a VOC, VUI, or VUM variant according to the WHO definitions. Highest genetic diversity was documented in the island of Majorca (42 different lineages detected). Globally, lineages B.1.1.7 and B.1.617.2/AY.X were identified as the 2 major lineages circulating in the Balearic Islands during the pandemic, distantly followed by lineages B.1.177/B.1.177.X. However, in Ibiza/Formentera lineage distribution was slightly different and lineage B.1.221 was the third most prevalent. Temporal distribution analysis showed that B.1 and B.1.5 lineages dominated the first epidemic wave, lineage B.1.177 dominated the second and third, and lineage B.1.617.2 the fourth. Of note, lineage B.1.1.7 became the most prevalent circulating lineage during first half of 2021; however, it was not associated with an increased in COVID-19 cases likely due to severe social restrictions and limited travels. Additional spike mutations were rarely documented with the exception of mutation S:Q613H which has been detected in several genomes (n = 25) since July 2021.Conclusion: Virus evolution, mainly driven by the acquisition and selection of spike substitutions conferring biological advantages, social restrictions, and size population are apparently key factors for explaining the epidemic patterns registered in the Balearic Islands.

This study aims to describe Limboto Lake's condition based on the spatial-temporal abundance of phytoplankton and the presence of harmful algae species. Sampling was conducted in February, March, and April 2018 at six stations. The phytoplankton found in Limboto Lake consisted of 7 divisions from 80 species, namely Chlorophyta (35 species), Euglenophyta (17 species), Bacillarophyta (13 species), Cyanophyta (7 species), Cryptophyta (4 species), Dinophyta (3 species) and Chyrosphyta (1 species). The results of the phytoplankton distribution analysis in Limboto Lake varied on average among stations as well as observation times. The results show that the average of phytoplankton abundance at stations 1, stations 2, stations 3, and stations 4 categorized as medium polluted waters with 4,903 ind/L, 5,000 ind/ L, 9,418 ind/L, and 10,049 ind/L, respectively. The abundance at station five is included in the lightly polluted category with an average phytoplankton abundance of 1,541 ind/L, while station 6 is in the heavily polluted category with the average value of 20,894 ind/L. Species that can be used as indicator species for pollution are those with the highest abundance value, namely Microcystis sp., which indicates that Limboto Lake contains high nitrate and phosphate.

The article presents scientific-methodical and practical principles for assessment of key territories of the ecological network of Eastern Podillya based on the main criteria of their formation. It offers the system of appropriate approaches and principles to be applied for formation of the key territories of the region's ecological network. The principle of representativeness should serve as a main criterion for selection of the key territories, however, we still advise to consider three types of such territories – biotic (botanical, zoological, mycological); geographical (landscape; biogeographical); geozoological (object; categorical; functional). Such aspects as area, size, configuration, state of internal ecological balance should play a significant role in creating the key territories, however, the qualitative and quantitative composition of protected objects, degree of anthropogenic impact on natural and man-made ecosystems and types of conservation regimes are also extremely important. Matrix representativeness, which is widely used in EU countries, should be also of great importance in forming a network of key territories. It is based on the landscape-zonal principle, where the systems of natural zoning units (biogeographical, geobotanical, floristic, forest typological, zoogeographical, physical-geographical) form the matrix of biodiversity species and landscapes. According to this principle, the basis for creation of key territories should by all means include typical (indicator) species of biodiversity, landscapes of all natural zones, subzones, regions, provinces, sub-provinces, districts. The field surveys of Eastern Podillya led us to a conclusion that a significant number of key territories do not perform a function of preserving biotic and landscape diversity. The conducted field researches allowed establishing the fact that there is a risk of losing such diversity under current ecological conditions of the region. Therefore, using the principle of representativeness, we presented a method of assessing the key territories of the Eastern Podillya's ecological network based on the main criteria of their formation. The main criteria include degree of naturalness of a certain key territory, its floristic and faunistic significance, landscape-coenotic and specific (relating to species) representativeness, purpose of a key territory, and its protected status (regime).
