Opis:
In Poland 6 species of Galliformes are breeding and 3 of them are open-farmland species of birds: Pheasant Phasianus colchicus, Partridge Perdix perdix and Quail Conturnix coturnix. In last years an exponential decline in number of birds in farmland is observed. The main reason of this situation is fast development of agriculture, using of fertilizers, farmland monocultures, soil erosion, the cutting of small field woods and increasing population of predators, such as the Foxes Vulpes vulpes, Racoon Dogs Nycteresus procyonoides or crows Corvus corone. In addition, the series of severe, cold winters and rainy springs caused limitation of insects availability, which are the main food of the young birds.

Opis:
A rich molluscan fauna was found in the outcrop of slope sediments and calcareous tufas in the valley of the Ociemny Stream in the Pieniny Mts. The malacological sequence identified there represents the entire Holocene, but it contains several stratigraphical gaps. From this viewpoint, it is a unique finding within the area studied. In nine samples, 11,000 specimens of 71 species of molluscs were identified. The ecological and zoogeographical diversity of the composition and structure enabled the separation of three faunistic assemblages. The oldest assemblage (with Discus ruderatus) corresponds with the cold period of the Early Holocene and represents shadowed habitats overgrown with the coniferous forests of the taiga type. Its characteristic feature is the presence of glacial relics (e.g. Vertigo genesii and Vertigo geyeri). The other younger fauna (with Discus perspectivus) is typical of the humid and warm climate of the Atlantic Phase. It is characteristic of the habitats of mixed and deciduous forests. Numerous Balkan and Mediterranean thermophilous forms appear in this assemblage. The youngest malacoenosis (with Bithynella austriaca) is typical for the historical times. The particular intervals containing molluscan fauna are separated by gaps corresponding to the erosion phases. Because of the land relief in the valley of the Ociemny Stream, which is not conducive to the development of human economy, no marked anthropogenic deforestation occurs.

Opis:
The geopark Altai has a set of unique geological, geographical, and archaeological objects. Its basis is made by geological space with a specific relief that plays an important role, and on certain sites, it takes the first place in comparison with other types of objects. The peculiar feature of the geopark Altai is that in its territory there is a landscape connection among archaeological, geological, and geographical objects, which at certain sites is penetrated by mental and cultural fluids causing a deep interest of tourists in this territory. In this regard, the authors consider the relief as an object of cognitive, educational, and practical activities of the geopark Altai. Therefore, the following tasks were set up: to find a site for the realization of several types of activities by the geopark and to develop a theoretical scientific and a popular science base for their implementation. As a result of the work done, the authors allocated the site within the boundaries of the geopark Altai where modern dynamics of the relief are characterized by the maximum speed. On this site, it is possible to recreate the processes that created the relief in the geological past and to study these processes now. The specifics of weather and climatic conditions in this region made its relief very important for economic activity of the population inhabiting this territory. Therefore, as of today, the study of the condition of certain surface sites and forecasting the development of relief-forming processes is an important part of any activity on the described territory. The long-term geological, ecological, geographical, and archaeological research conducted by the authors on the territory of the Altai Republic served as materials for this study. The geological materials were collected by the methods adopted in this field of research (field survey of structures and rocks, cartographic methods, analysis of general geological data, and others). The ecological and geographical results were obtained using geochemical, hydrochemical, analytical, and others.

Opis:
W pracy w oparciu o materiał kartograficzny z czterech różnych przekrojów czasowych, wykorzystując kartograficzną metodę badania zmian środowiska, przeanalizowano zmiany biegu Prosny na odcinku od Kalisza do jej ujścia. Ustalono, że w okresie od drugiej połowy XVIII wieku do początku XXI wieku nastąpiły znaczne zmiany. Zaobserwowana transformacja była podyktowana czynnikami naturalnymi i antropogenicznymi. Te pierwsze obejmowała głównie odcinanie meandrów i zmiany głównego koryta powodowane przejściem wezbrań powodziowych. Do drugich można zaliczyć wszelkie prace hydrotechniczne, związane np. z prostowaniem rzeki, umacnianiem jej brzegów, budową wałów przeciwpowodziowych, itd.
This work analyses the changes in the course of the Prosna River between Kalisz and the river's mouth. The analysis is based on the cartographic material from four different periods, and has taken advantage of the cartographic method of examining environmental changes. It has been established that considerable changes took place in the period between the second half of the 18th century and the beginning of the 21st century. The transformation observed was caused by natural and anthropogenic factors. The former included mainly cutting off the meanders and the changes of the main river bed caused by flood waters flow; the latter comprise all kinds of hydrotechnical works related, for example, to straightening the river , enforcing its banks , building the flood banks, etc.

Opis:
Malacological analysis was used to reconstruct Holocene environmental changes from profiles of calcareous tufa and fluvial deposits exposed in the Kobylanka stream valley, several kilometres west of Kraków in southern Poland. The abundant and diversified mollusc fauna was characterized by clear variability within the vertical succession where five types of molluscan assemblages were distinguished. The pattern of sedimentary and molluscan facies allowed characterization of two main intervals of environmental change during Holocene. In the lower interval, until the end of the Middle Holocene, human activity was not detected and environmental processes were controlled by natural factors. In the upper interval, corresponding to the Late Holocene, human impact can be seen, in the form of rapid deforestation and agricultural development. Anthropogenic impact has been particularly evident during the last millennium. The mollusc assemblages studied allowed accurate reconstruction of natural and anthropogenic factors affecting the natural environment.

Opis:
A detailed malacological analysis was made of sediments associated with a small landslide which had developed on the north-eastern slope of Majerz Hill near Niedzica (Inner Carpathians, Southern Poland). The age of the development and environmental changes associated with particular phases of the landslide was determined by means of radiocarbon dating. The analyses made it possible to distinguish two periods of landslide activation falling on the turn of the Early/Middle Holocene and on the Late Holocene (probably on the Iron Age Cold Period). These phases are closely related to periods of increased mass movements, both of landslides and debris flows in other European mountains, stages of glacial advance in the Alps, periods of increased fluvial activity in rivers and elevated water levels in European lakes. The molluscan assemblages also enabled the reconstruction of environmental conditions before the landslide formation, during periods of dormancy, and after the end of its activity.

Opis:
Investigations have been carried out in order to reconstruct the palaeoenvironmental changes during the earliest Pleistocene interglacials and to establish their relation to global environmental changes. Three sections in east Lithuania exposing the earliest Pleistocene lacustrine deposits lying between the Kalviai (Glacial B, Nidanian?) and Dzūkija (Sanian 1) and between Dzūkija (Sanian 1) and Dainava (Sanian 2) glacial deposits were selected for study. Until now the Šlavė-2 and Vindžiūnai-136 successions were considered to have formed during the Vindžiūnai (Augustovian?, Malopolanian) Interglacial and the Kudrė-915 succession during the Turgeliai (Cromerian IV, Ferdynandovian) Interglacial. Geochemical, palaeomagnetic, magnetic susceptibility, anisotropy of magnetic susceptibility and palaeobotanical proxies were applied to establish the cyclicity and dynamics of palaeoenvironmental change. The data obtained enable the subdivision of the section into units related to changes in the sedimentary environment. The Matuyama/Brunhes boundary and Jaramillo subchron of the Matuyama chron have been recognized in the Šlavė section. The results enable correction of the stratigraphic position of the sections studied. The sedimentation in the Šlavė section took place during the Early Pleistocene, while that at the Vindžiūnai-136 and Kudrė-915 took place during two different Middle Pleistocene interglacials.

Opis:
During the construction of the S-3 road near Gorzów Wielkopolski, a sedimentary succession of the Eemian Interglacial and the older part of the Weichselian Glaciation were exposed. The succession, ~22 m thick, consists of lacustrine and fluvioglacial deposits. Lake sediments, mainly calcareous gyttja with peat intercalations, represent the infills of two palaeolakes. The almost complete skeleton of a forest rhinoceros, Stephanorhinus kirchbergensis, and a bone of the fallow deer Dama dama were found in the older lake deposits. Mollusc shells were numerous in both lake sequences, analysis of which revealed two types of assemblage, representing the coastal, littoral zone of a shallow lake with a muddy bottom. The sequence of mollusc communities observed in vertical succession allowed reconstruction of environmental changes during deposition. Several hydrological changes have been recognized within the palaeolake, especially water level fluctuations probably due to climate change.

Opis:
Small water bodies, occurring behind barriers across valleys, create very advantageous conditions for the sedimentation of calcareous tufas. These sediments usually contain rich and diversified malacocoenoses. The composition and structure of these associations are closely linked to environmental changes during the accumulation of the sediments. At the Sulisławice locality, the remnants of two barriers, composed of hard, calcareous tufa, were found. Behind them, sequences of granular, calcareous tufas were preserved, forming terraces, elevated up to 3 m above the level of the present stream bed. The age of the sediments was obtained from radiocarbon dating and is referable to the Atlantic Phase. The rich malacofauna, occurring in these tufas, permitted the recognition of four types of faunistic association, in a sequence that corresponds to phases in the development of the water bodies. Three of them are characterised by the dominance of aquatic species and permit the reconstruction of specific features of the body of water. In the fourth association, terrestrial species predominate. A detailed, malacological analysis was the basis for a model of the evolution of the water bodies, occurring behind the barriers. The model is more widely applicable to the sediments of similar origin, frequently found in upland regions of Poland and other parts of Europe.

Opis:
W pracy podjęto próbę rekonstrukcji pierwotnych warunków środowiskowych, tj. sprzed okresu budowy grodu i miasta, a głównie hydrologicznych i hipsometrycznych warunków, oraz określono, jak wpłynęły one na pierwotny układ miasta oraz jak zmieniały się w okresie późniejszym. Najstarsze osadnictwo w Poznaniu na Ostrowie Tumskim rozwijało się na terasie zalewowej. Analiza archeologicznych i geologicznych materiałów z obszaru Poznania dostarczyła informacji o miąższości utworów nasypowych. Pozwoliło to następnie zrekonstruować przedosadniczą powierzchnię terenu, dawne stosunki wodne i wilgotnościowe i szybkość narastania różnego typu warstw akumulowanych w obrębie obszaru miejskiego. Analiza najstarszych map Poznania umożliwiła rekonstrukcję sieci hydrograficznej w dolinie Warty i jej zmiany. Z kolei analizy tekstów źródłowych z XII–XVII w. pozwoliły na odtworzenie zmian rzeźby terenu przyległego do Ostrowa Tumskiego i lokalizację kilku ostańców wyższych poziomów terasowych w dolinie Warty. Dominacja prac odwodnieniowych w obrębie miasta w ostatnich dwóch wiekach, likwidacja terenów podmokłych i licznych odnóg Warty spowodowały, że Poznań stał się przesuszony, a więc zupełnie inny niż w średniowieczu.
In this work an attempt was made to reconstruct the initial environmental conditions within the city i.e. prior to its foundation, as well as the hydrological and hypsometric conditions and determine how they affected the origin and later development of the city. The oldest settlement in Poznań in Ostrów Tumski developed on the flood plain. Analysis of the oldest maps of Poznań helps the reconstruction the hydrographic pattern in Warta valley and its changes. Analysis of archeological and geological materials from the Poznań area provided information on the thickness of deposits which helped reconstruct the pre-settlement surface, old water relations and the speed whit which layers accumulated over centuries. Analysis of source texts from the 12th–17th centuries helped reconstruct changes in the relief of the terrain adjacent Ostrów Tumski and determine a few island mountains of the higher terrace levels in the Warta valley. The dominance of drainage works in the city area in last two centuries, liquidation of wet areas and river pattern made the city terrain very dery – completely different than in the Middle Ages.

Opis:
The organic-rich material has been studied from the bottom part of lacustrine sediments of the Lake Kasuciai, western Lithuania. Radiocarbon dates and palaeobotanical data showed that these sediments accumulated between 13,500 and 9000 14C yr BP. The Late Glacial interstadial is defined by the dominance of Characeae and accumulation of carbonate. The Bolling is characterized by the pioneer taxa and the communities of open habitats. During the Allerod pine replaced the light demanding taxa that show development of a closer woodland habitat and dryness of climate. The short period between Bolling and Allerod with increasing representation of Betula and plants typical for the highly eroded habitats could be correlated with Older Dryas. The onset of the Younger Dryas is marked by degradation of the forest cover and expansion of heliophytic grasses. Entire vegetation cover with birch and pine forest was settled during the Preborial. Formation of calcareous sediments and appearance of thermophilous taxa confirm the climatic amelioration.

Opis:
Interdisciplinary investigations (pollen and diatom analysis, 14C dating and geological-geomorphological and archaeological data) around Lakes Duba and Pelesa, in SE Lithuania, have elucidated the environmental history and human impact throughout the Late Glacial and Holocene. Aerial photograph interpretations indicate that both lakes are residual basins of one Post-Glacial palaeolake outside the morainic relief of the Nemunas (Weichselian) Glaciation. Pollen assemblages from lacustrine deposits date back to the Older Dryas (Lake Duba) and Alleröd (Lake Pelesa) and cover all chronozones of the Post-Glacial. Diatom analysis has illustrated the palaeoecological conditions in the lakes and helped reconstruct successive water levels throughout the last 12300 radiocarbon years. Diatom abundance and the distribution of the planktonic, benthic and epiphytic species suggest a lowering of Lake Duba and Lake Pelesa at (e.g.) 11900-10900 14C BP, (e.g.) 10000-8100 14C BP and (e.g.) 3700-2500 14C BP. Pollen data suggest that the earliest signs of human impact and local forest clearances data from about (e.g.) 8400-8300 14C BP. The first record of cereal pollen in sediments dates from earlier than (e.g.) 6000 14C BP. Therefore, agriculture was introduced into the area not earlier than the second half of the Midle Neolithic, at about (e.g.) 5000-4400 14C BP. Continous indications of agriculture and progressive clearing of woodland is consistent with the increasing role of a farming economy during the Bronze Age. Since the 1800-1900 14C BP formation of an open canopy, increasing soil erosion and changes in vegetation emphasize the remarkable human impact on the environment.

Opis:
The lithological and malacological studies covered sediments forming the low terrace of the Rogoźnik Stream in the northwest part of the Podhale Basin. This terrace is characterised by a uniform structure within a significant part of the valley. Three layers of gravel and four layers of sandy and silty muds were found there. A rich and diversified malacofauna was discovered in fine-grained sediments. Its analysis allowed us to characterise environmental conditions during sediment deposition. The age of the individual components of the sedimentary sequence was determined by radiocarbon dating. A distinct change was found in the upper intervals of the sequence, corresponding to the warm phase of the Medieval Climate Optimum. This period is associated with the robust development of agriculture, and processes related to human activities became the main factor shaping the environment, influencing the course of geological processes, and changing the taxonomical and ecological structure of the fauna and flora assemblages found in this area.

The currently observed increase in human activity in the Arctic accelerates the negative impact on the environment as well as increases the risk of threats to mankind itself. This paper reviews and summarises a selection of studies on the interaction between humans and the environment in the Arctic coastal zone, which is impacted by a warming climate and associated geohazards. The paper presents a general description of human presence in the Arctic, identifies and describes the processes that are threatening the infrastructure, and the anthropogenic processes that have a negative impact on the Arctic. It considers the possible future economic opportunities, and presents the sustainable requirements for modern human activity in the Arctic. The paper demonstrates the urgent need to develop a common, Arctic-wide strategy based on sustainable development. The time has come to change human perception of the Arctic because, in the near future, it may be considered as a refuge for climate change refugees.
