A palaeohydrological record of a complete Eemian series from Żabieniec Ża-19 (Garwolin Plain, Central Poland) with reference to palaeoclimate data

The aim of this study was to reconstruct the evolution of the Eemian palaeolake in the Żabieniec site (Garwolin Plain, Central Poland); it identifies changes in the water level and the trophic status of the lake resulting from panregional factors, including climate changes occurring during individual phases of the last interglacial, and local geologic-geomorphological factors shaping the palaeoenvironment using multi-proxy methods (palaeobotanical analyses, subfossil Cladocera and diatoms analyses as well as determinations of the stable isotopes). A record was obtained of all seven Regional Pollen Assemblage Zones (RPAZs) according to Mamakowa’s description of the Eemian pollen succession (1989), and of the changes in microfossil assemblages and isotopes in palaeolake sediments associated with lake evolution. Special attention was paid to the Middle Eemian RPAZ 4 (ie hazel phase) of the climatic optimum; all proxies associate this with the highest water level and a warm humid climate. During the E5/E6 RPAZs, the eutrophic lake transformed very quickly, and a transitional peatbog was formed. The higher humidity of the late Eemian resulted in another increase in water level. The multi-proxy record of the Żabieniec palaeolake which we obtained was compared to those of other Eemian water bodies in the Garwolin Plain and in Central Poland that exhibit sedimentation gaps especially during the younger part of the E5 RPAZ.

Role of Diatom Flora in the Forensic Diagnosis of Drowning Cases from some Water Bodies in the Delta Region.

In forensic studies of death issues, the body of victims have been found in the water, and by using the diatom test, it could be determined whether the cause of death is related to drowning or not. One more critical problem occurs, when the victim was killed and thrown into the water, was he/she alive at the time of drowning? Therefore, the diatom species in the water of six different sites from two canals (Mit-Yazid and Tanbara Haweis canals, the Delta region, El-Gharbia government, Egypt) were analyzed and the physicochemical parameters for these sites were measured to diagnose the cause of death of ten cases found in the studied canals, and determining the accurate site of death. In the present research, the water samples from six different sites of Mit-Yazid and Tanbara Haweis canals were collected during the time of victim's collection in 2021. The diatom frustules were extracted by the acid digestion of the …

High-resolution insight into the Holocene environmental history of the Burullus Lagoon in northern Nile delta, Egypt

The modern Nile delta developed in the Middle and Late Holocene, and at its most northern-central point is situated at the Burullus Lagoon, which is environmentally diverse, including salt marshes, mudflats, and sand plains, and separated from a sea by a sand barrier overtopped with high sand dunes. The lagoon has been fed since the Middle Holocene by the Sebennitic branch of the Nile and marine intrusions through the Bughaz inlet. A sediment core (BO-1) was collected at the northeastern shore of the lagoon and sampled at centennial scale resolution in order to reconstruct the development of the lagoon. The results show that an initial and limited lagoon had developed at the end of the Early Holocene, but after a dry period ca. 7.2 cal ka BP it has been progressively transformed into a marshy area, with occasional inflows of sea water. Lower water level and higher salinity of the Burullus Lagoon at 6.0–5.5 …

Palynological studies on the Upper Cretaceous Wata and Matulla formations in Bakr Oil Field, Gulf of Suez, Egypt

Palynological investigation of the subsurface Upper Cretaceous (Turonian-Santonian) Wata and Matulla formations in three wells drilled in the Bakr oilfield, Gulf of Suez area is presented. 147 species of palynomorphs (spores, pollen dinoflagellate cysts and prasinophytes green algae) are identified. A Turonian-Santonian age is suggested based on the occurrences of many diagnostic taxa such as Liliacidites farafraensis, Droseridites senonicus, Ephedripites ambiguus, Isabelidinium cooksoniae, Isabelidinium glabrum, Odontochitina porifera, Odontochitina costata, Canningia reticulata and Trichodinium castanea. The paleoenvironmental reconstruction of the studied interval indicates the carbonate-dominated Wata Formation was deposited during the Turonian transgressive condition and the Matulla Formation which is consist of clastic-dominate deposited during the Coniacian-Santonian regressive phase. The presence of Palm Province pollen such as Arecipites, Retimonocolpites and Longapertites associated with the pteridophytes spores refer to a tropical humid climate in the area of deposition. The abundance of green algae Pediastrum and occurrences of Crybelosporites water fern indicate discharge of freshwater into the basin.

2400 years of climate and human-induced environmental change recorded in sediments of Lake Młynek in northern Poland

In the densely forested Warmia and Masuria region (northern Poland) there are many small endorheic lakes characterized by their low sedimentation rate, which makes them excellent archives of Holocene environmental and palaeoclimatic change. Lake Młynek, located near the village of Janiki Wielkie, was selected for multi-faceted palaeoenvironmental research supported with radiocarbon dates. Sediments from this lake also contain unique information about human impact on the environment, because a stronghold has been operating on its northern shore since the early Iron Age to the early Medieval period, giving the opportunity to correlate palaeoenvironmental data with the phases of human activity over the last 2400 years. During the second and third centuries BCE the lake was surrounded by a dense deciduous forest. From the first century BCE to second century CE the forest around the lake was much reduced, which can be associated with the first pre-Roman (La Tène) and Roman occupation phase evidenced by the construction of the stronghold located close to the lake. From the second up to ninth century CE gradual restoration of the forest and a decline in human activity took place, along with lake deepening and the onset of a colder and humid climatic phase which corresponded to the global cooling episode known as the Bond 1 event (1.5 ka BP). The next intensive phase of forest clearing around the lake occurred between the 9th–13th century CE as result of human activity (Middle Age settlement phase of the stronghold). Whilst this period is marked by a warming, the human impact which has transformed the landscape …

A high-resolution pollen and diatom record of mid-to late-Eemian at Kozłów (Central Poland) reveals no drastic climate changes in the hornbeam phase of this interglacial

In the region of 20 newly-found fossil lakes in the Garwolin Plain (Central Poland), formed during the Eemian interglacial (MIS 5e), the Kozłów site is considered one of the longest examples of sequences of palaeolake deposits. Pollen investigations have revealed an entire Eemian interglacial (MIS 5e) with a very long hornbeam phase. Repeated coring allowed for high-resolution pollen and diatom analysis to be used in tracing climate-driven palaeoenvironmental changes during the mid- and late-Eemian. The resulting thick series of organogenic deposits from Kozłów joins the collection of existing high-resolution long records of this interglacial in central-eastern Europe. It should be emphasized that a very good correlation was found between palynological and diatom data, which allows for drawing consistent conclusions. The warm and humid climate of the Corylus phase at the onset of the mid-Eemian was …

Environmental and climate change during the Late Saalian–Eemian Interglacial at the Struga site (Central Poland): A diatom record against the background of palynostratigraphy

The main aim of the study was to determine the environmental history and climatic change taking place during the Late Saalian/Eemian transition, particularly at the start of the Eemian interglacial. Paleolake sediments from two cores from the Garwolin Plain (Central Poland) were subjected to diatom analysis. Altogether, 63 genera including 335 species and varieties were recognized. A clear shift in diatom composition was observed, from an assemblage dominated by periphytic species including Fragilaria sensu lato taxa to a planktonic one comprising Cyclotella sensu lato species. These changes in diatom assemblages and the relative abundance of the dominant and sub-dominant taxa indicated fluctuations in water level and regional climate oscillation. The transition from the Late Saalian to the Eemian was marked by a gradual increase in the contribution of summer-blooming diatom species, indicating the …

Diatom assemblages from surface sediments of two coastal Lagoons, the central part of the Red Sea, Saudi Arabia and their associated environmental variables

The composition and distribution pattern of diatom assemblages in the surface sediments of Sharm Al-Kharrar and Al-Shuaiba lagoons, situated on the central part of the Red Sea coastline of Saudi Arabia, were analyzed. A total of 191 diatom species from 53 genera were identified. A highly diverse diatom flora dominated by the genera Mastogolia, Amphora sensu lato, Lyrella, and Navicula sensu lato species was observed. Diatom species composition showed the dominance of the benthic forms over the epiphytic and planktonic ones, which can be attributed to the shallowness of the environments. The relationship between the recognized diatom taxa and measured environmental variables was explored using multivariate statistical techniques. Hierarchical ascending clustering and detrended correspondence analyses differentiated six representative diatom assemblages in each Lagoon. Canonical …

Study of phytoplankton flora and its use as a biomonitoring tool to determine the water quality of Krishnasayar Lake, Burdwan, West Bengal, India

The present study focused on biomonitoring approaches involving the phytoplankton composition, density and diversity, and their relationships, with changes in environmental variables, and to determine the pollution status of Krishnasayar Lake in the Burdwan District of West Bengal, India. A total of 29 phytoplankton taxa belonging to Chlorophyceae (13), Cyanophyceae (9), Bacillariophyceae (5) and Euglenophyceae (2) were observed. The phytoplankton density exhibited a maximum value of 12,633 cells/litre in the post‐monsoon season and a minimum value of 7,266 cells/litre in the pre‐monsoon season. The results of two multivariate proficiencies (cluster analysis; CCA) indicated the distribution of phytoplankton groups are influenced by pH, electrical conductivity, and the nitrate, phosphate, potassium and dissolved oxygen concentrations. Various diversity indices, including the Shannon–Wiener Diversity …

New record of charophytes (Characeae, Charophyta) from Socotra Island, Indian Ocean, Yemen

The charophyte flora from Socotra Island, Indian Ocean, studied for the first time from streams waterbodies that distributed at the northern part of the Island. The recognized charophyte taxa were taxonomically investigated, and four dominant species belonging to family Characeae are identified as Chara braunii, C. globularis, C. hispida and Lamprothamnium papulosum. These taxa are reported as a new record for algal flora of Socotra Island. A brief account of the environment where the charophytes were found is provided, as a first evaluation of the ecological requirements of Indian charophytes. A taxonomically diverse of charophyte assemblage and ecological variables explain abiotic features of biotope as shallow (max 1.3 m), alkaline fresh (pH 7.5–8.4), slightly saline, and moderate eutrophic.
