Human impact on a small barrier reef meadow of Posidonia oceanica L, various human activities and environmental effects research papers. Delile on the north Tyrrhenian coast Italy. The health status of an emerging Posidonia oceanica meadow, subject to high human impact, was studied. Biometric variables, heavy metals, PAHs and C, various human activities and environmental effects research papers, N, P contents were determined in sediment and seagrass samples. The meadow was found to The meadow was found to grow under oligotrophic conditions and an increase in nutrient content was only recorded in autumn.
In sediment, Hg exceeded its ERL effects range low and sometimes also its ERM effects range mediumand Cu was close to its ERL. In leaves, Hg and Cu were relatively high but below their respective ERLs. Sediments close to the meadow various human activities and environmental effects research papers heavily contaminated with pyrolytic PAHs, some of which exceeded their ERLs.
oceanica did not show major accumulation of PAHs, lighter molecules predominating. Despite 40 years of intense human activity, meadow growth dynamics and contaminant accumulation did not suggest that the meadow was regressing. Save to Library. Holocene fire activity during low-natural flammability periods reveals scale-dependent cultural human-fire relationships in Europe.
The PREDICTS database: a global database of how local terrestrial biodiversity responds to human impacts. Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project — and avert — future declines.
We describe and assess a new database of more than 1. The database contains measurements taken in of ecoregions, 13 of 14 biomes, 25 of 35 biodiversity hotspots and 16 of 17 megadiverse Existing global databases of…. The sedimentary infilling of the moat surrounding the Villaggio Piccolo of the Terramara Santa Rosa di Poviglio was analysed in order to obtain palaeoenvironmental inferences from sediments and pollen assemblage. The high-resolution The high-resolution stratigraphic sequence preserves evidence of the environmental changes that occurred in the Po Plain, in Northern Italy, during the Late Holocene, various human activities and environmental effects research papers.
Our interdisciplinary approach permitted to study climatic and anthropic contributions to the environmental changes in this region. The relationships between these changes and land-use changes were investigated focussing on adaptive strategies of the Terramare people during the Middle and Recent Bronze ages e yr BC.
The Terramare are archaeological remains of banked and moated villages, located in the central alluvial plain of the Po river. The Terramara of Santa Rosa consists of two adjoining settlements Villaggio Grande and Villaggio Piccolo ; the moat that separates the two parts of the site is c.
Chronology is based on archaeological evidence, stratigraphic correlations and radiocarbon various human activities and environmental effects research papers. Pedosedimentary features and biological records pollen of aquatics and algal remains demonstrate that shallow water, probably subjected to seasonal water-level oscillations, has always been present in the moat.
In the lower units of the sequence, the laminations indicate standing water, while occurrence of reworked pollen testified the supply of sediments to the plain from catchment zones located in the Apennine. Open vegetation was widespread; economy was based on wood management, fruit collection on the wild or from cultivated woody plants, crop fields with a fairly diversified set of cereals especially increasing in variety during dryness or phases of water crisis.
Probably, grapevines were cultivated near the moat, where various human activities and environmental effects research papers wet habitat was favourable to the growing of wild plants. The extraordinary high-resolution of this sequence makes visible the management of woods including coppicing at the Middle Bronze and early Recent Bronze ages. The economy of Santa Rosa di Poviglio should have been probably less based on animal breeding than it was in the other Terramare villages already studied for pollen.
This research also confirms the chronological correspondence between an environment stressed by dry conditions and the collapse of the Terramare civilization. Manifestation of Remotely Sensed Data Coupled With Field Measured Meteorological Data for an Assessment of Degradation of Urmia Lake, Iran.
Urban soil resources of medium-sized cities in Poland: a comparative case study of Toruń and Zielona Góra. Purpose Despite the many studies of urban soils, a comparative analysis for cities of a similar size has not yet been conducted. Thus, the aim of this review paper was to compare the soil distribution patterns in the area of two Thus, the aim of this review paper was to compare the soil distribution patterns in the area of two medium-sized Polish cities Toruń and Zielona Góra.
The authors attempted to answer the question of how natural and technogenic factors contributed to the transformation of urban soils and what the similarities and differences are between these two studied cities. Materials and methods First, both the natural and the human-related including historical factors influencing the soil formation in the studied cities were analysed. Then, a comparison of the degree of transformation of the urban soil environment was presented. The data obtained by the authors during nearly two decades of research over soil profiles were used.
Results and discussion Intensive development of the built-up areas in Toruń brought heavy and long-term transformations of soils, wh Fires: the main human impact on past environments in Patagonia?
Climate variability and human impact in South America during the last years: synthesis and perspectives from pollen records. An improved understanding of present-day climate variability and change relies on high-quality data sets from the past 2 millennia.
Global efforts to model regional climate modes are in the process of being validated against, and Global efforts to model regional climate modes are in the process of being validated against, and integrated with, records of past vegetation change.
For South America, however, various human activities and environmental effects research papers, the full potential of vegetation records for evaluating and improving climate models has hitherto not been sufficiently acknowledged due to an absence of information on the spatial and temporal coverage of study sites. This paper therefore serves as a guide to high-quality pollen records that capture environmental variability during the last 2 millennia.
We identify 60 vegetation pollen records from across South America which satisfy geochronological requirements set out for climate modelling, and we discuss their sensitivity to the spatial signature of climate modes throughout the continent.
Diverse patterns of vegetation response to climate change are observed, with more sim Archaeopedological analysis of colluvial deposits in favourable and unfavourable areas: reconstruction of land use dynamics in SW Germany.
Colluvial deposits, as the correlate sediments of various human activities and environmental effects research papers soil erosion, depict an excellent archive of land use and various human activities and environmental effects research papers history as indicators of human-environment interactions. This study establishes a chronostratigraphy of This study establishes various human activities and environmental effects research papers chronostratigraphy of colluvial deposits and reconstructs past land use dynamics in the Swabian Jura, the Baar and the Black Forest in SW Germany.
In the agriculturally favourable Baar area multiple main phases of colluvial deposition, and thus intensified land use, can be identified from the Neolithic to the Modern times. In the unfavourable Swabian Jura increased colluvial deposition began later compared to the more favourable areas in the Baar. The same holds true for the unfavourable areas of the Black Various human activities and environmental effects research papers, but intensified land use can only be reconstructed for the Middle Ages and Early Modern times instead of for the Bronze and Iron Age as in the Swabian Jura.
Land use intensity and settlement dynamics represented by thick, multilayered colluvial deposits increase The effects of environmental and visitor variables on the behavior of free-ranging ring-tailed lemurs Lemur catta in captivity, various human activities and environmental effects research papers. The effect of the zoo environment on captive animals is an increasingly studied area of zoo research, various human activities and environmental effects research papers, with visitor effects and exhibit design recognized as two of the factors that can contribute to animal welfare in captivity.
It is known It is known that in some situations, visitors may be stressful to zoo-housed primates, and this may be compounded by environmental factors such as the weather, the time of day, and zoo husbandry routines. Exhibit design and proximity of the public are also known to influence behavioral response of primates to visitors; however, there is minimal research on free-ranging zoo animals, even though they are potentially subjected to intense interactions with visitors.
The current study explores the effect of the zoo environment, several visitor variables and specific animal-visitor interactions on the behavior of free-ranging ring-tailed lemurs Lemur catta at Fota Wildlife Park, Ireland.
Pollen-based quantitative reconstruction of Holocene vegetation in Varna Lake area Northeastern Bulgaria using modelling and simulation approach. ABSTRACT Analysis of the fossil pollen assemblages of lacustrine sediments can be used to study the vegetation dy-namics and human impact on the natural vegetation. Different models describe the spread and accumula-tion of pollen around Different models describe the spread and accumula-tion of pollen around the sample site and provide an excellent opportunity for quantitative reconstruction of vegetation coverage.
The Varna Lake is the largest by volume and deepest liman along the Bulgarian Black Sea Coast, and therefore, pollen found in its sediment samples is representative of the regional vegetation from a large area. This report aims to create a calibrated model on the basis of modern pollen, vegetation and environmental data and then to reconstruct the past vegetation and to simulate landscapes in the GIS environment. A detailed pollen analysis was performed on the cm of the cm Core-3 obtained from the Varna Lake at a water depth of 6 m.
The Extended R-Value ERV model was used to relate pollen percentages to vegeta-tion composition within a certain area, by taking the pollen productivities and fall speed of different taxa into account Sugita, Models of pollen disper-sal and deposition were applied in order to reconstruct likely past landscape scenarios from fossil pollen as-semblages using the software suite HUMPOL v. Vegetation communities and their composition were simulated in GIS environ-ments and possible vegetation maps were drawn.
The modern pollen samples together with the cor-responding vegetation data were collected and digital maps were created. Five vegetation communities are recognized as well as two types of non-pollen produc-ing areas. The application of the ERV model for simu-lation of contemporary landscape around Varna Lake calculates distance weighted plant abundance estimates of pollen productivity for use as correction factors.
Measurement of goodness-of-fit between pollen and vegetation data are presented as the Relevant Source Area of Pollen RSAP by calculating the likelihood function scores against the distance from the sample point.
Three submodels of the ERV model are tested and show similar results but ERV model 3 was selected and gives an RSAP of m for this landscape. Standard intuitive interpretation of the pollen as-semblages suggest six stages of development of veg-etation in the Varna Lake area. Numerous 50 km by 30 km landscape simulations were performed at the four time-windows in the past. Impacts of human interventions on the evolution of the Ria Formosa barrier island system S.
Human interventions on sandy barriers disturb natural barrier dynamics, to the extent of having become key forces in modifying geomorphological evolution. This work identifies natural and human-induced drivers and analyses their This work identifies natural and human-induced drivers and analyses their importance to the multi-decadal evolution of the Ria Formosa barrier island system, in South Portugal.
Aerial photographs from the last six decades and historical maps are used to assess changes in cross-shore rates, morphological characteristics barrier and dune widths, inlet morphology and migration and barrier areas, through systematic methods that can be easily transferred to other barrier systems. Interventions, and especially hard engineering ones jetties, inlet stabilisationsaffected barrier evolution trends.
Shore-perpendicular works increased shoreline progradation updrift and initiated coastal retreat downdrift, with strongest erosive impacts along the edges of the system. Inlet stabilisations changed tidal inlet hydrodynamics and initiated ebb-shoal attachment to the barriers on either side of a non-migrating inlet that experienced loss of tidal prism.
