Palaeoenvironmental evolution of the Baltic Sea basin during the Last Interglacial (Eemian, Mikulino stages): a review

Boreas, EarlyView.
This review presents an investigation of the evolution of the Baltic Sea basin and its connections through the Eemian Stage, based upon sequences of marine and associated deposits from the White Sea to the Southwest Baltic, via the Karelian channel. Pollen analyses, foraminiferal and ostracod analyses provide the evolution of relative sea‐level change,

Stratigraphic evidence for modern‐like glacier extents in south‐central Alaska within the last glacial period (MIS 3)

Boreas, EarlyView.
The last (Wisconsinan) glacial period was punctuated in North America by two glacial maxima, known as the Early and Late Wisconsinan glaciations. In Alaska, these maxima and their subsequent retreats have been the object of dating efforts to reconstruct local climatic events and compare them to global trends.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Palaeolandscape reconstruction of a shallow coastal embayment in Kattegat, Denmark—influence of sea‐level changes during the latest Pleistocene and Holocene

Boreas, EarlyView.
We analyse the geological processes of a coastal embayment in the Kattegat. Using high‐resolution seismic data and sediment cores, we describe a geological evolution from glacial to shallow marine stages with a variety of preserved facies from different depositional settings, including glacio‐lacustrine, telmatic, limnic and coastal environments.

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

Boreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Late Holocene moisture variability in Arctic Alaska from chitin δ18O

Boreas, EarlyView.
Amplified warming in the Arctic has resulted in reduced sea‐ice extent, which can impact regional climate dynamics. Elucidating past moisture variability in response to changing temperatures and sea‐ice conditions can offer insight into how anthropogenic climate change may impact Arctic areas such as the Alaskan North Slope in the future. We contribute

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

Boreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Environmental DNA for invasive rat surveillance and biosecurity on islands

Conservation Science and Practice, EarlyView.
We collected aquatic eDNA samples from beach and lake sites on three atoll islands with different invasion statuses before and after a rat eradication operation. Two dozen eDNA samples can confirm with ≥95% probability the presence of invasive rats prior to any management intervention. However, following the eradication operation, neither targeted eDNA

Integrating ecological feedbacks across scales and levels of organization

Ecography, EarlyView.
In ecosystems, species interact in various ways with other species, and with their local environment. In addition, ecosystems are coupled in space by diverse types of flows. From these links connecting different ecological entities can emerge circular pathways of indirect effects: feedback loops.

Factors Influencing the Stocking of Juvenile Pikeperch (Sander lucioperca)

Fisheries Management and Ecology, EarlyView.
ABSTRACT Predator species of fish play crucial roles in ecosystem balance through top‐down control, a mechanism frequently exploited in biomanipulation to stock predator species. Juvenile pikeperch (Sander lucioperca) were stocked (n = 52,887) in spring 2023 and 2024 and autumn 2023 to compare stocking efficiency between Recirculation Aquaculture ...
