Abstract. Lake Ohrid is located at the border between FYROM (Former Yugoslavian Republic of Macedonia) and Albania formed during latest phases Alpine orogenesis. It deepest, largest oldest tectonic lake in Europe. To better understand paleoclimatic paleoenvironmental evolution Ohrid, deep drilling was carried out 2013 within framework Scientific Collaboration on Past Speciation Conditions (SCOPSCO) project that funded by International Continental Drilling Program (ICDP). Preliminary results...
Early Eocene global climate was warmer than much of the Cenozoic and punctuated by a series transient warming events or 'hyperthermals' associated with carbon isotope excursions when temperature increased 4–8 °C. The Paleocene-Eocene Thermal Maximum (PETM, ~55 Ma) 2 (ETM2, 53.5 hyperthermals were short duration (<200 kyr) dramatically restructured terrestrial vegetation mammalian faunas at mid-latitudes. Data on character magnitude change in during after PETM ETM2 high northern latitudes,...
Significance Forest conservation and restoration are important means to counter threats caused by habitat fragmentation global change. Diverse resilient forests can only be maintained if we understand their sensitivity past climate The sedimentary record of the oldest extant lake in Europe, Lake Ohrid (North Macedonia, Albania), shows survival extinction tree species during glacial interglacial stages (G–IG) Quaternary. Pollen analysis reveals that area was an effective refuge for...
Abstract. This study reviews and synthesises existing information generated within the SCOPSCO (Scientific Collaboration on Past Speciation Conditions in Lake Ohrid) deep drilling project. The four main aims of project are to infer (i) age origin Ohrid (Former Yugoslav Republic Macedonia/Republic Albania), (ii) its regional seismotectonic history, (iii) volcanic activity climate change central northern Mediterranean region, (iv) influence major geological events evolution endemic species....
High resolution pollen analysis of mid- to late-Holocene peat deposits from southwest Florida reveals a stepwise increase in wetland vegetation that points an increased precipitation-driven fresh water flow during the past 5,000 years. The tight coupling between winter precipitation patterns and strength El Niño-Southern Oscillation (ENSO) strongly suggests paleo-hydrology record reflects changes ENSO intensity. A terrestrial subtropical outside Indo Pacific Warm Pool both documents...
Mediterranean mid-altitude sites are critical for the survival of plant species allowing elevational vegetation shifts in response to high-amplitude climate variability. Pollen records from southern Balkans have underlined importance region preserving diversity over at least last half a million years. So far, there no and dynamics Balkan refugia with an Early Pleistocene age. Here we present unique palynological archive such refugium, Lake Ohrid basin, recording continuously floristic...
A volatile assemblage of short-lived endemic species developed into a stable community long-lived in Lake Ohrid.
In the open world, categorical classes are imbalanced, test not known a priori, and data captured across different domains. Paleontological can be described as open-world, specimens may include new, unknown taxa, collected, such measurements or images, standardized studies. Fossil pollen analysis is one example of an open-world problem in paleontology. Pollen samples capture large numbers specimens, including only common types but also rare even novel taxa. diverse morphologically features...

Recurrent phases of increased pine at Lake Tulane, Florida have previously been related to strong stadials terminated by so-called Heinrich events. The climatic significance these has interpreted in different ways. Using a pollen–climate inference model, we quantified the climate changes and consistently found that mean summer precipitation (P JJA) (0.5–0.9 mm/day) November temperature (2.0–3.0°C) during coeval with events Younger Dryas. Marine sea surface records indicate potential sources...
Abstract. Detailed, stratigraphically well-constrained environmental reconstructions are available for Paleocene and Eocene strata at a range of sites in the southwest Pacific Ocean (New Zealand East Tasman Plateau; ETP) Integrated Discovery Program (IODP) Site U1356 south Australo-Antarctic Gulf (AAG). These have revealed large discrepancy between temperature proxy data climate models this region, suggesting crucial error model, or both. To resolve origin discrepancy, detailed needed from...
Studies of the upper 447 m DEEP site sediment succession from central Lake Ohrid, Balkan Peninsula, North Macedonia and Albania provided important insights into regional climate history evolutionary dynamics since permanent lacustrine conditions established at 1.36 million years ago (Ma).

ABSTRACT The Brown Bank Formation (BB Fm) is a clay‐rich sedimentary unit that distributed over large area in the southern North Sea. It easily recognisable 2D acoustic reflection profiles, forming sets of subparallel high‐amplitude reflections. Previous studies have provided only fragmentary information on facies, and variety interpretations depositional environment age BB Fm. In this study we combine high‐resolution profiles multiproxy sedimentological, geochemical geochronological...
