We conducted a complex investigation of anthropogenic roadside phytocoenoses. For the study, 8 plots (birch and pine forests) were selected, close to roads in the south of Tyumen region within the five administrative districts: Uporovsky, Zavodoukovsky, Yalutorovskiy, Yarkovsky, and Tobolsk. As a result of the studies, 75 species of vascular plants from 21 families were noted in the plant communities. It was found that the majority of the total projective cover of the plant communities was provided by synanthropic species. In the synanthropic fraction of the flora, 33 species belonging to 11 families were identified, those with the most species being: Scrophulariaceae, Compositeae, Rubiaceae, Poaceae, Fabaceae, Polygonaceae, Umbellíferae. The index of synanthropization of the flora of the studied phytocenoses is in the range from 43% to 64%. Among the identified pollutants accumulated in the phytocenoses, the group of heavy metals was identified (Cr, Cu, Ni, Pb, Sr, Zn). Needles of Pinus sylvestris L. mainly accumulate Cr, Cu, Ni, Sr. The greatest concentration of Pb and Zn was found in the leaves of Betula pendula Roth. The content of other heavy metals in the leaves of Betula pendula Roth. during the growing season was relatively stable. Accumulation of heavy metals in the studied components of forest ecosystems can be displayed structurally: soil > leaves < phytomass (birch forests), soil < needles > phytomass (pine forests). Methodological approaches to conducting a complex of long-term observations of natural ecosystems have been formulated, substantiated and justified.

The problems of forest and land fires continue to overshadow in Riau Province and Pelalawan District including the contributors of fire spots of forest and land fires. The handling and control of forest and land fires run during this time tend to be incidental and focus on the aspect of fire suppression only. The extinguishing and controlling of forest and land fires fire has been undertaken by several agencies in the local government organization of Pelalawan District. While the relationship between the agencies is more information share and informational relationship and the deployment of resource assistance is limited to the capacity of each organization during the occurrence of forest and land fires only, not led to a collaborative multi-disciplinary working approach (inter-organizational collaborative network) in the area of local government. This research aims to Described the management situation of forest and land fires that took place in Pelalawan District, conducting analysis and academic studies on the practice of Network Inter-Organization by controlling forest and land fires (Karhutla) in Pelalawan District, and formulating model Inter-organizational network-based organizations that can be applied to regional government of Pelalawan District in every bureaucracy organizations. The study used a qualitative descriptive approach with reference to literature studies and interview reluct collection by (Agranoff & McGuire, 2003).

Ecotourism is a practice of utilizing natural ecosystems to support education and conservation efforts. In the Special Region of Yogyakarta (SRY), Indonesia, two mangrove ecosystems have been designated as protected areas and ecotourism sites. However, it is undeniable that the need for space for infrastructure development has been detrimental to these areas. This research set out to identify changes occurring nearby mangrove ecosystems and the impacts they would potentially have in the future. It used a triangulation method that combined secondary data analysis, observation, and primary data collection through in-depth interviews. The observed coastal environments experienced, among others, extensive conversion of agricultural land for the Yogyakarta International Airport (YIA) construction, increased tourism growth and pressures, and varying artificial modifications in parts of mangrove ecosystems utilized for mass tourism; all of which could disrupt sustainability and reduce the ecological functions of mangroves. Intensive aquaculture and iron sand mining in the vicinity could also negatively affect the mangrove ecosystem and ecotourism. Within a certain period, these anthropogenic activities are most likely to pose significant threats to the preservation of mangrove ecotourism. Regional spatial plans are an example of instruments required to regulate sustainable spatial planning and protect mangrove ecosystems.

The greatest problem for such kind of historical cities is reconstruction ways of their structure and types of construction. Considering characteristic cities and regional specifications of Iran by this goal, some researching that belonging to changing possible to environment resolution for their development was carried out. For example, Yazd got the most power in the last periods for out of city buildings according to its natural climate and social-economical opportunities. These are low-storied yard spaces, construction complexes and many-storied buildings. Adaptation matter to historical environment and adaptation character of new viewing buildings and multi-storied buildings of Iran are in other direction fully. It is a separated system of powerfully prepared group construction of multi-sectional manystoried buildings.

Aerial Survey Test Project with DJI Phantom 3 Quadrocopter Drone
The paper deals with the optimization of the aerial triangulation based on UAS images. The images were taken with a DJI Phantom 3 quadrocopter and they were measured in Photomod Lite ver. 4.4. The bundle adjustment was carried out twice; first in Photomod Solver and later in BINGO ver. 6.8. During the adjustment 14 ground control points were used and 31 points were calculated as new points. Using these new points we could compare the coordinates to the coordinates received from the high-precision field surveying measurements. From the coordinate differences the calculated RMS errors of horizontal coordinates are around one pixel size on the ground and to 2.5 pixels vertically. The final results showed us that a non-metric camera at low flight height with a quadrocopter can be used effectively and accurately at aerial surveys of relatively small areas.

In the present article, the patterns of the geographic variability in yields of rye within Polesia and the Forest-Steppe zone of Ukraine are presented and the correlation of the factors and dynamics of an agroeconomic and agroecological nature was determined. The dynamics of rye yields in the study area over time were determined as being characterized by three extreme points: two local maxima and one local minimum. Specific terms of the polynomial curve of the fourth order can be meaningfully interpreted and applied to describe the dynamics of productivity. Free members of the polynomial indicate culture productivity in the starting period. Dynamics of the productivity that can be explained by the regression indicate that agrotechnological and agrecological conditions of agricultural production are a pervasive factor that determines the presence of a general trend. The determination coefficient of the regression total trend can be interpreted as an indicator of the role of the agrotechnological and agroeconomic factors in the dynamics of productivity. The residue of the trend regression model can be interpreted so as to include the agroecological component of the rye yields dynamics.

One of the processes with the greatest impact on humanity in the second half of the twentieth century was global warming. Detection, estimation and prediction of trends are important aspects of climate research (Hansen and Lebedeff, 1987). Trends have become the most frequently used technique to identify climatic variability on a regional and local basis (Amadi et. al., 2014). Trend is a long-term change (increase or decrease) in a time series (Ragatoa, 2018). In the current context of climate change, we considered that a study on the evolution of air temperature in the last 35 years is needed, especially since it is the first study of its kind for this area. The aim of this study was to highlight long-term trends (magnitude and direction) in terms of air temperature (average, minimum, maximum, anomalies), at different time scales (multiannual, seasonal and monthly), in the city of Târgu Mureș, between 1986-2020. The analyzed data series come from the archive of the National Meteorological Administration with the records made by the local meteorological station. The analysis was performed using MS Excel spreadsheets with MAKESENS software to evaluate trend and data distribution (Mann-Kendall, Sen's slope, Kurtosis and Skewness). According to the results of the Mann-Kendall test and the estimation of the slope of Sen, there were statistically significant positive trends in the warmer months (June, July and August). Average temperature values increased by up to 1.6° C, and the average slope varied by 0.049° C / 35 years. Regarding the multiannual average, with one exception (2011), the last 13 years have shown positive trends. Consequently, the average annual temperature in Târgu Mureș shows obvious growth trends in the last 35 years.

During 1974–1978, the Lithuanian Institute of History published four volumes of the Lietuvos archeologijos atlasas (Atlas of Lithuanian Archaeology). The atlas’s first book, which was edited by Dr habil. Rimutė Rimantienė, was devoted to Stone and Bronze Age sites and stray finds from this period (Atlasas 1974). The separate article of this book (Bagušienė, Rimantienė 1974) encompassed all of the ground stone artefacts that had been mapped and were preserved at that time in Lithuanian museums. The work listed 2560 ground stone artefacts from 1420 find spots and created distribution maps, an index of the main types, and a typology scheme, which Lithuanian archaeologists and museologists have used for almost half a century. The typological scheme of ground stone artefacts created by Ona Bagušienė and Rimutė Rimantienė is seen not as an unalterable constant, but as a dynamic, modifiable classification structure. The article presents insights and thoughts that arose in creating a ground stone artefact database for SW Lithuania (Užnemunė). And examines the most abundant ground artefact typological group, perforated stone axes.

The State of Alaska is located in the north-western North America. Its area of 1 717 854 km2 is populated by 731 449 people (as 2012). Population density is low, only 0.5 person per square km. The main reason for the low population density are unfa-vourable natural conditions, the most important of which include climate, permafrost and topography.Alaska’s landscape diversity is a consequence of the variety of terrain types. For that reason, there are 8 national parks (Denali National Park, Gates of the Arctic National Park, Glacier Bay National Park, Katmai National Park, Kenai Fjords National Park, Kobuk Valley National Park, Lake Clark National Park, Wrangell-St. Elias National Park), national monuments and other lower rank protected areas established in Alaska. Each of these places, characterized by unique types of landscape (for example: glaciers, active volcanoes, fjords, high mountains) brings millions of tourists per year from the USA and all over the world. All these protected areas are very important for the development of tourist industry, and thus for the economy of USA. Alaska’s national parks draw about 2 million visitors annually

Roadside-tree stands are an important and characteristic element of the landscape communities from the Warmińsko-Mazurskie voivodeship. But there is no accurate data on the current state of conservation of the different alleys and proposals for their protection. The article presents the results of field research on the inventory and synthetic characterization of tree alleys occurring in Jonkowo commune and the type and number of trees needed to complete individual roadside-tree stands. It was noted that, despite the advanced age of the trees and improperly conducted treatments, relatively large and dense network of line-trees stands with a large wealth dendroflora, with the vast majority of native species, has survived to this day. Additionally “place of conflict” and tree alleys demonstrating additional value cultural were determined. Presented data resulted in the creation of “Local program of development of roadside-tree stands in the Jonkowo commune” submitted to the commune for implementation. Obtained results will also facilitate monitoring of changes occurring within individual alley and taking appropriate action.

From the first half of the XX century, the maritime Antarctic was a region with high regional warming rates. At the beginning of the XXI century, regional warming strongly slowed down, but during the next twenty years the near-surface temperatures and mean annual precipitation at the Antarctic Peninsula will most probably increase. Higher temperatures and precipitation make the conditions in the maritime Antarctic more favourable for plants, including invasive species. Moreover, the increasing number of Antarctic tourists unintentionally transport thousands of seeds to the Antarctic on their clothes and equipment. In such circumstances, it is important to evaluate possible defensive mechanisms of native plant species, including their allelopathic potential. The objective of this study was to evaluate the allelopathic potential and cytostatic activity of Sanionia georgicouncinata. This species is widespread in the maritime Antarctic and is one of the most abundant moss species on the Argentine Islands (Wilhelm Archipelago). Seeds of cucumber Cucumis sativus, radish Raphanus raphanistrum subsp. sativus, wheat Triticum vulgare, and amaranth Amaranthus paniculatus were used as bioassay species. Fresh green biomass of S. georgicouncinata was used to prepare aqueous extracts with 1 : 10, 1 : 50, and 1 : 100 plant to water ratios. The average root length of wheat sprouts and cucumber sprouts in distilled water did not differ significantly from those in plant extracts. The root length of radish sprouts in 1 : 50 plant extract was significantly shorter than in distilled water. Meanwhile, in 1 : 50 and 1 : 100 water extracts, roots of amaranth plants were significantly longer than in water. The number of lateral roots of cucumber sprouts in water and studied aqueous extracts varied from 1 to 6 with medians from 3 to 4. The medians of control (distilled water) and sample groups (aqueous extracts) did not differ significantly, but only 38.1 ± 6.1% of cucumber sprouts developed lateral roots in the 1 : 10 aqueous extract of S. georgicouncinata, and even less – 28.3 ± 7.5% in the 1 : 50 aqueous extract. The results of this study show that the allelopathic potential of S. georgicouncinata is low. However, a significant cytostatic activity of the studied extracts shows that this species may still affect other plants and animals. Further research is needed to evaluate the impact of the studied extracts on root growth and germination of the invasive plants, particularly Poa annua.

Altınova is a delta formed by alluvium carried by Madra river filling the east edge of depression extending in the direction of NW-SE between Edremit and Çandar depressions. Rising of the sea level after the last glacial maximum (Holocene transgression) led to significant changes in the Altınova-like coastal regions and the shoreline was reshaped. In order to reveal these changes, 22 drilling holes were drilled in Altınova between 1995 and 1998, and 10 drilling holes were drilled between 2012 and 2015.The paleogeography and geoarchaeology of the delta-coastal basin were evaluated by analysis of drilling samples and C14 dating. As a result of the research, three main periods were determined in the alluvial development of Altınova in the Holocene.These; Early Holocene transgression period, Middle Holocene marine sedimentation period, Late Holocene deltaflood plain development. It was determined that the first settlement, Yeniyeldeğirmeni Höyük (Early Bronze), was located along the 5000 BP coast and there were an old lagoon and a coastal barrier in part of this coast extending to the north of the delta. The shoreline that has been filled with alluvial deposits has been progressing seaward for the last 7000 years but after the construction of the Madra dam, it has begun to progress landward.

The paper presents basic information concerning bioclimatic conditions in Łódź based on the Tourism Climate Index (TCI). The index makes it possible to assess in a comprehensive manner, based on specified meteorological parameters, the climatic conditions affecting the development of tourism. The study uses measurements from the weather station, Łódź-Lublinek, taken in the years 1966-2014. The TCI values have a distinct annual pattern with the highest values recorded in summer. The summer season has the highest frequency of days with ‘very good’ or ‘excellent’ conditions for tourism. An assessment of the variability of bioclimatic conditions indicates an increase in the number of days with high TCI values pointing to ‘very good’ or ‘excellent’ conditions for tourism and recreation.

With the regulation of the rivers vast areas along the Tisza River were drained. As a result of this process flood plain farming gave way to the cultivation of field crops. However, the traditional forms of farming survived on the river flats between the dikes and the river and in the early 20th century vines and fruit trees were planted on the higher areas here outside many settlements along the Tisza River. The cultivation of vines in a manner adapted to the ecology and natural conditions of the river flats in Szentes resulted in the production of table grapes in quantities exceeding the subsistence level, for sale on the market. The article attempts primarily to explore the natural conditions determining this special form of cultivation. The most important natural factor is the periodical inundation during floods which fundamentally influences the course of grape production. The author examines how people farming in these areas are able to adapt to the harsh natural conditions, how they organise the cultivation and whether this ecological adaptation can be regarded as successful and viable.

The helminthofauna of Bombina bombina (Linnaeus, 1761) has been studied to an unequal degree in different parts of the habitat. Thus, it has been studied in more detail in the west of its range (in the countries of central and eastern Europe) and in less detail in the center (in Belarus and Ukraine). There were few data on helminths of this host in the east of its range (in Russia). For the first time, an inventory of the helminthofauna in B. bombina was carried out for populations in the Volga River Basin. The results of our own research are presented and supplemented with information from other authors. We summarized scattered data on helminths from 390 specimens of amphibians collected over more than 40 years in the territory of five regions: Kaluga and Samara regions, the Republics of Mordovia, Tatarstan and Bashkortostan. The helminthofauna includes 21 species from three classes: Trematoda (15), Chromadorea (5) and Clitellata (1). For each species, we give the systematic position, localization, places of detection, geographical distribution and characteristics of the life cycle. The leech Helobdella stagnalis (Linnaeus, 1758) was first recorded in the European fire-bellied toad in Europe. Four species of trematodes are new to this amphibian species in Russia: Haematoloechus abbreviatus (Bychowsky, 1932), Paralepoderma cloacicola (Luhe, 1909), larvae, Tylodelphys excavata (Rudolphi, 1803), larvae and Astiotrema monticelli (Stossich, 1904), larvae. Another species of trematode – Strigea strigis (Schrank, 1788), larvae – was first recorded in this host within the boundaries of the Volga Basin. A specific parasite is the trematode Haematoloechus abbreviatus (Bychowsky, 1932). The number and composition of the species of helminths of the European fire-bellied toad vary in different regions; the structure of the helminth fauna is generally stable and includes three groups of species: adult and larval stages of trematodes, adult nematodes-geohelminths. The results of the study create a database for further population studies and contribute to the development of ideas about the distribution and formation of the amphibian helminth fauna in Europe, Russia and the Volga Basin.

Anatolian geography is one of the important countries of the world in terms of endemic plants. There are 12 000 plant species in Europe, including 2,750 endemic species. According to the most up to date, Anatolia has an endemic diversity that is no different in the world due to its natural bridge between the three continents, its diverse geographical features and the diversity of its geographical diversity and one of the three plants we see in our country is endemic, and unfortunately there are many plant and animal species facing the danger of extinction. Due to its geographical location, Turkey hosts about 12 000 herbivores, 120 mammals, more than 400 birds, 130 reptiles and 300 fish 542 species. Endemic species that grow in Anatolia are naturally exposed to various hazards such as extreme animal pressures, fire, unconscious cutting, dismantling, breeding work, settlement, urbanization and herbicide use. It is of utmost importance that this extraordinary wealthy biological diversity which Anatolia has preserved for thousands of years has been transferred to future generations. By creating strong awareness in the fulfillment of this humanitarian mission, our route must be permanently determined.
