Insect migrations are spectacular natural events and resemble a remarkable relocation of biomass between two locations in space. Unlike the well-known migrations of daytime flying butterflies, such as the painted lady (Vanessa cardui) or the monarch butterfly (Danaus plexippus), much less widely known are the migrations of nocturnal moths. These migrations - typically involving billions of moths f

Small animals that winter at northern latitudes need to maximize energy intake and minimize energy loss. Many passerine birds use night-time hypothermia to conserve energy. A potential cost of night-time hypothermia with much theoretical (but little empirical) support is increased risk of night-time predation, due to reduced vigilance and lower escape speed in hypothermic birds. This idea has neve

OBJECTIVE: Familial risks of anxiety have been assessed in small case-control studies, usually based on reported, but not medically verified, anxiety in family members; thus the degree of familial clustering of these diseases remains to be established.METHODS: The Multigeneration Register, in which all men (sons) and women (daughters) born in Sweden from 1932 onward are registered together with th

US-based philanthropies have long contributed to environmental conservation through non-repayable donations, but some are now beginning to embrace novel investment strategies that are profit-orientated. From the vantage points of political economy and geopolitics, this article investigates the potential ramifications of this shift in funding for large-scale marine protected areas (LMPAs), which ha

Tau neuronal and glial pathologies drive the clinical presentation of Alzheimer's disease and related human tauopathies. There is a growing body of evidence indicating that pathological tau species can travel from cell to cell and spread the pathology through the brain. Throughout the last decade, physiological and pathological tau have become attractive targets for AD therapies. Several therapeut

Sensitivity analysis consists of an integral and important validatory check of a computer simulation model before the code is used in performing any kind of analysis operation. The present paper demonstrates the use of a relatively new method and tool for conducting global sensitivity analysis (GSA) for environmental models, providing simultaneously the first GSA study of the widely used 1d soil-v

The low-temperature structural phase transitions of Bi, Pb, In and Sn-doped samples of thermoelectric Zn 4 Sb 3 have been characterized on crystals grown from molten metal fluxes, using electrical resistance and single crystal X-ray diffraction measurements.
