Size spectra are important descriptors of community structure and can indicate changes in community functioning in response to shifts in environmental conditions. There are relatively few assessments of benthic size spectra, and most are based on summer samples alone. Processes influencing size spectra, such as recruitment and predation pressure, vary seasonally, and understanding this variation is ...

The present study investigates the dependence of the local auroral electrojet (AEJ) intensity on solar illumination by statistically examining northward geomagnetic disturbances in the auroral zone in terms of the solar zenith angle χ. It is found that on the dayside, both westward and eastward electrojets (WEJ and EEJ) are more intense for smaller χ, suggesting that the solar extreme ultraviolet‐induced ...

The snowy mountains of the world attract more and more backcountry recreationalists. Besides beauty and joy, traveling in avalanche terrain can involve risk of injury and even death. A correct assessment of avalanche danger and following a correct decision is crucial. This requires a thorough evaluation of a range of factors. To aid these decisions several decision-making frameworks (DMF) have been ...

The evolution of the Olga Basin region in the northern Norwegian Barents Sea and its relation to the Caledonian and Timanian orogenies is poorly understood due to sparse geophysical data and the lack of well control. In 2015, the German Federal Institute for Geosciences and Natural Resources (BGR) acquired deep multichannel seismic lines as well as gravity and magnetic data. The new seismic data ...

Phonological variation can be defined as describing “a situation in which a single morpheme can be realized in more than one phonetic form in a single environment” (Coetzee & Pater, 2011, p. 401). In the latter decades, research on this integral part of grammar has become increasingly important, resulting not only in a growing literature on the topic, but also in large datasets on which hypotheses ...

Numerous astronomical observatories were established across Europe over the course of the eighteenth century, rendering astronomy a distinct sub-branch of the Republic of Letters. Arguably, by the mid eighteenth century astronomy functioned as a denominationally neutral space and constituted a scientific discipline in the modern sense. Jesuits, Benedictines, Lutherans, Anglicans, Calvinists – all ...

<i>Objective</i>: We investigated whether levels of current physical activity (PA) contribute to the established relationship between cardiorespiratory fitness (CRF) and cognition in schizophrenia and whether brain-derived neurotrophic factor (BDNF) or its precursor proBDNF mediates this relationship. <p> <p><i>Method</i>: Sixty-one outpatients with schizophrenia spectrum disorders participated. ...

Eukaryotic multicellularity originated in the Mesoproterozoic Era and evolved multiple times since, yet early multicellular fossils are scarce until the terminal Neoproterozoic and often restricted to cases of exceptional preservation. Here we describe unusual organically-preserved fossils from mudrocks, that provide support for the presence of organisms with differentiated cells (potentially an ...
