Palaeoenvironmental changes recorded at the Velika Vrbica loess‐palaeosol sequence, Wallachian Basin, during MIS 3–MIS 1

open access: yesBoreas, EarlyView.
This study presents a detailed investigation of the Velika Vrbica loess‐palaeosol sequence, situated in the Wallachian Basin of northeastern Serbia, with the aim to reconstruct palaeoenvironmental changes spanning Marine Isotope Stages (MIS) 3 to 1. Using optically stimulated luminescence (OSL) dating, low field magnetic susceptibility (χlf), and mass ...

Trans-Saharan migratory patterns in Vanessa cardui and evidence for a southward leapfrog migration

open access: yesiScience
Summary: Some insects, such as the painted lady butterfly Vanessa cardui, exhibit complex annual migratory cycles spanning multiple generations. Traversing extensive seas or deserts is often a required segment of these migratory journeys.

A 3200‐year weathering record of the Mekong River basin by sediments from the South China Sea

open access: yesBoreas, EarlyView.
The Mekong River is a mega‐river in East and Southeast Asia, and precipitation in its watershed influences more than 300 million people. However, the controlling factor in precipitation and weathering in the basin remains controversial. Here we present a high‐resolution record of weathering of the Mekong River basin over the past 3200 years by ...

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

open access: yesBoreas, 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

open access: yesBoreas, 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.

A Conceptual Framework and Methods for Studying the Connectivity of Fishes

open access: yesFish and Fisheries, EarlyView.
ABSTRACT Connectivity is a multifaceted concept that has important implications for the management and conservation of marine and freshwater fishes. We developed a conceptual framework that encompasses multiple, interrelated categories of connectedness, including landscape (e.g., structural, functional) connectivity and ecological (e.g., trophic ...

Optical pumping of 5s4d^{1}D_{2} strontium atoms for laser cooling and imaging

open access: yesPhysical Review Research
We present a faster repumping scheme for strontium magneto-optical traps operating on the broad 5s^{2}^{1}S_{0}−5s5p^{1}P_{1} laser cooling transition. Contrary to existing repumping schemes, we directly address lost atoms that spontaneously decayed to ...

Comparative analysis of metabolic and functional cardiac alterations in diet‐ and genetically induced mouse models of cardiac dysfunction

open access: yesThe FEBS Journal, EarlyView.
Dietary and genetic stress trigger different routes to heart failure. In mice, a carbohydrate‐free high‐fat diet caused mitochondrial dysfunction and impaired energy production with preserved pumping function, while genetic obesity led to heart enlargement, fibrosis, and reduced function.
