The Anthropocene is characterized by dramatic ecosystem changes driven human activities. impact of these activities can be assessed different geochemical and paleontological proxies. However, each proxies provides only a fragmentary insight into the effects anthropogenic impacts. It highly challenging to reconstruct, with holistic view, state ecosystems from preindustrial period present day, covering all biological components, prokaryotes multicellular eukaryotes. Here, we used sedimentary...
The rapid urbanization and industrialization of Kuwait the consequent effluent discharges into marine environments have resulted in a degradation water sediment quality coastal ecosystems such as Bay. This study investigates ecological response benthic foraminifera (protists) to environmental stress traditional morphological approach was compared innovative DNA (eDNA) metabarcoding evaluate status (EcoQS). Forty-six surface samples were collected from selected stations To detect pollution...
The benthic foraminiferal assemblages in Lake Varano (southern Italy) have been investigated detail. Statistical analyses enable us to recognize two main biotopes and five sub-biotopes that reflect different ecological environmental conditions. mainly seem be influenced by the hydrological (namely salinity) sediment conditions lake. These are characterized specific sub-assemblages variations relative species’ abundances. Outer Biotope is affected marine influence dominated species Ammonia...
In this study, the meiofaunal diversity in Lake Varano (southern Italy) is investigated detail. Using a statistical approach, these data were coupled with physicochemical parameters of bottom water and sediment characteristics order to understand factors influencing biodiversity distribution. The lake selectively influenced by different factors, namely: organic matter grain-size, as well salinity. Although assemblages appear be poorly diversified, index values are similar those generally...
The Middle Eocene Climatic Optimum (MECO; ~40 Ma), which interrupted for ~500–600 kyr the long-term cooling trend culminating at Eocene/Oligocene boundary, still requires a comprehensive understanding of biotic resilience. Here we present high-resolution integrated foraminiferal and calcareous nannofossil study across MECO from expanded continuous Tethyan Baskil section (eastern Turkey) that offers complete magneto-biostratigraphic geochemical framework. five phases identified reveal...
Abstract The Opalinus Clay, a silty to sandy claystone formation, Early Middle Jurassic (Toarcian and Aalenian) in age, has been selected as the host rock for deep subsurface disposal of radioactive waste Switzerland. Over past thirty years, numerous geotechnical, mineralogical, sedimentological studies have conducted on Clay within framework Nagra (National Cooperative Disposal Radioactive Waste) drilling campaigns Mont Terri Project, an international research program dedicated study...
The Sepetiba Bay (SB), located in the state of Rio de Janeiro (SE Brazil), is a transitional ecosystem highly anthropized. Because its great environmental, economic, and social importance, SB has been target several studies to investigate sources pollution their environmental impact. However, on response foraminifera are rare. This study applies for first time Ecological Quality Ratio (EQR) based biotic index exp(H’ bc ), related foraminiferal diversity, coupled with granulometric,...
Abstract Purpose Some marine organisms can be used as Biological Quality Elements to estimate the degree of environmental impact and monitor health benthic habitats. Organisms with mineralized protections, such foraminifera, provide helpful information on evolution coastal system over a long period determine Paleo-Ecological Status (Paleo-EcoQS). This work aims at reconstructing Paleo-EcoQS in heavily anthropized Sepetiba Bay (SB; Rio de Janeiro State, SE Brazil). Materials methods is based...
Foraminifera (Rhizaria) and testate amoebae (Rhizaria Amoebozoa) are single-celled organisms with marine continental affinities. They regarded as valuable bioindicators in transitional areas such tidal salt marshes have been widely used for (paleo)-environmental characterization. Along-lasting debate regularly occurs on the use of living vs. dead fauna to accurately represent modern environments. Moreover, environmentally based benthic foraminiferal amoebaean studies need a reliable sampling...
In the last three decades, benthic foraminiferal ecology has been intensively investigated to improve potential application of these marine organisms as proxies effects climate change and other global phenomena. It is still challenging define most important factors affecting communities derived faunistic parameters. this study, we examined abiotic-biotic relationships in central-southern area Adriatic Sea using modern machine learning techniques. We combined gradient forest (Gf) structural...
