Caloplaca herbidella (Hue) H. Magn. and C. furfuracea H. Magn. are two isidiate, epiphytic species in the large genus Caloplaca. Caloplaca herbidella in a strict sense is normally grey and fertile with thick, somewhat coralloid isidia, but orange, sterile forms with thin isidia also occur. Caloplaca furfuracea is superficially similar morphologically to C. herbidella s. str. but has thinner, more

Food-hoarding birds use memory to relocate caches, and species that store thousands of scattered food items must have an extraordinary memory capacity to be able to relocate them. Because the hippocampus is important in the functioning of spatial memory, it is logical to assume that the amount of food stored should correlate with hippocampal volume. Previously, food-hoarding capacity has been used

Relict spinel grains (similar to 25-250 mu m in diameter) from decomposed extraterrestrial material in Archean to Recent sediments can be used to reconstruct variations in the flux of different types of meteorites to Earth through the ages. Meteorite falls are rare and meteorites weather and decay rapidly on the Earth surface, making it a challenge to reconstruct ancient fluxes. Almost all meteori

Climate change poses a serious challenge to sustainable urban development, placing many cities at risk. Climatic conditions are changing to such an extent that the capacity of urban institutions and associated governance systems to deal with climatic extremes and variability is being reduced. New approaches for urban climate change adaptation are thus urgently needed. There is an increasing conse

The spruce seed moth, Cydia strobilella L., is a serious pest on cones of spruce (Picea spp.) in the Holarctic region. Previous studies from different parts of its area of distribution have reported conflicting results on the composition of its sex pheromone. By gas chromatography with electroantennographic detection, coupled gas chromatography-mass spectrometry, a Y-tube olfactometer bioassay, an

Treatment of type 3 von Willebrand disease (vWD) relies on infusion with plasma-derived factor concentrates containing von Willebrand factor (vWF). Patients with types 1 and 2 vWD who do not respond satisfactorily after receiving desmopressin need treatment with concentrates. The rationale for long-term prophylaxis in vWD is obvious: prophylaxis has been successfully used in hemophilia, and joint

The measurement of ATP as an estimate of microbial biomass C in humus was studied. Three different acid extractants, H2SO4, TCA and H3PO4 were compared, as well as two different buffers, Tris and arsenate. No difference in extraction efficiency was found when the light output was converted to ATP content using internal ATP standards, but the different extraction agents and buffers influenced the l

Partial migration is often considered a transitory stage between migration and residency, and whether partial migrants take weather conditions into account during migration is largely unknown. To assess whether partial migrants differ from regular migrants in their responses to weather, we compared the migratory intensity of a partial migrant, the Blue Tit (Cyanistes caeruleus), with more regular

En ny europeisk studie granskar hur allmänheten i sex länder ser på organtransplantationer och postnatala genetiska test. Det rör sig om Cypern, Österrike, Tyskland, Frankrike och Sverige. I undersökningen framkommer att de tillfrågade personernas funderingar följer två övergripande spår: Här finns å ena sidan tankar om den medicinska utvecklingens potential, å andra sidan reflektioner rörande desRecent developments in the field of biomedicine do not only constitute a challenge for the health care systems of modern societies. They also have a profound impact on the core concepts of individual and collective life. The corresponding changes of individual and collective identities take place within the framework of different historically shaped national conditions and traditions. This leads t
