The Arctic is one of the fastest‐warming marine regions in the world, which is changing the timing of seasonal sea‐ice dynamics. The annual summer breakup of sea‐ice coincides with resource pulses, which provide critical food sources for consumers to exploit. Marine organisms respond behaviourally to exploit these resources, with some migrating to presumably maximize feeding opportunities, whereas others remain resident, provi...

The Early Devonian Hunsrück Slate of Germany provides a unique glimpse of the composition and diversity of the marine biota of the mid-Paleozoic, but understanding long has been hindered by problematic preservation. Exemplifying both the unique nature of the Hunsrück fauna and the limitations of preservation, the three genera and three species of the family Erinaceasteridae (class Stenuroidea, subphylum Asterozoa ,) are discus...

Purpose During rapid exposure to hypobaric hypoxia (HH), arterial oxygen tension and haemoglobin oxygen saturation decrease. The oxygen dissociation curve (ODC) describes the relationship of oxygen tension and haemoglobin oxygen saturation. Previous methods for ODC determination are mostly limited to standard conditions (40 mmHg PCO 2 , 37 °C), and measurements of 2,3-bisphosphoglycerate (2,3-BPG) and adenosine triphosphate (A...

Energy is the currency of exchange within ecosystems which defines the strength and influence of interactions, particularly between predator and prey. The ability to estimate the productivity of an ecosystem is, therefore, dependent upon the estimation of consumer diet contents and their energetic quality. To estimate growth, reproduction, and, ultimately, survival of individuals, measures of prey quality for predators are ess...

Anadromous rainbow smelt ( Osmerus mordax , [Mitchill 1814]) are found along the northeast Atlantic coastline of North America, with their range now limited to north of Cape Cod, Massachusetts, USA. Although their anadromous life cycles are described broadly, gaps remain regarding how adult rainbow smelt use estuaries post‐spawning, including movement behaviors, habitats used, and specific timing of emigration to coastal water...

Removing greenhouse gases from the atmosphere is a major challenge for today’s society. A great source of potential for greenhouse gas sequestration is beneath our feet: agricultural soil. By accumulating soil organic carbon in soil, farmers can sequester carbon dioxide and simultaneously reach soils more resilient to extreme weather events. To encourage farmers to build up humus and thus sequester carbon, some humus programme...

The incidence of aortic valve stenosis (AoS) increases with age, and once diagnosed, symptomatic severe AoS has a yearly mortality rate of 25%. AoS is diagnosed with transthoracic echocardiography (TTE), however, this gold standard is time consuming and operator and acoustic window dependent. As AoS affects the arterial blood pressure waveform, AoS-specific waveform features might serve as a diagnostic tool. Aim of the present...

The xylariaceous genus Dematophora has recently been resurrected and segregated from Rosellinia based on a molecular phylogeny and morphological characters. This was an important taxonomic change because Dematophora in the current sense contains several important pathogens, while Rosellinia is limited to mainly saprotrophic species that have an endophytic stage in their life cycle and may even have beneficial effects on the ho...
