“No Delay?” – Online teaching using low latency technology. Playing music together using low latency technology has been possible for some years now, provided fast and robust digital networks. The accessibility of low latency networks has been limited, and the available software has been complicated to install and use. At the music conservatory in Tromsø, associate professor Geir Davidsen has ...

Nordlysobservatoriet i Tromsø ble høytidelig innviet 6. august 1930. Et 25-års jubileum ble markert med en tilstelning 30. juli 1955. Ved 25-års jubileet i 1955 ble det utarbeidet et festskrift - men det var ikke penger til å få det trykt. Desto gledeligere er det at vi til 50-års jubileet får anledning til et spesialhefte av OTTAR for å beskrive Nordlysobservatoriets historie og virksomhet, et hefte ...

Paleofire records document fire’s response to climate, ecosystem changes, and human-activity, offering insights into climate-fire-human relationships and the potential response of fire to anthropogenic climate change. We present three new lake sediment PAH records and a charcoal record from the Lofoten Islands, Norway to evaluate the Holocene fire history of northern Norway and examine human impacts ...

Birds allocate substantial resources to their eggs during the laying period, resources also needed for other concurrent costly processes such as mate acquisition, nest building and site defence. Egg and clutch sizes may thus vary in response to food availability prior to egg laying. We investigated the variation in egg and clutch size of black-legged kittiwakes Rissa tridactyla in a North Norwegian ...

Te new species <i>Amphilochus anoculus</i> <b>sp. n.</b> is described based on material from the IceAGE programme and the preceding BioIce programme; it is separated from the closely related <i>Amphilochus manudens</i> by the absence of eyes, a ...

The identity and distribution of a neglected fungus gnat species, Rymosia tolleti Burghele-Balacesco, 1965, in Europe is reviewed based on examination of newly collected specimens as well as available museum materials. Rymosia tolleti is widespread but rather rare in Central Europe, with confirmed records from Romania, Slovakia, Germany, and France. All the specimens with known collection details ...

Two Norwegian uristid amphipods, obligate associates of sea anemones, have for a long time been confused sub nomine <i>Onisimus normani</i> Sars, 1890. In reality this species only occurs in south Norway, while the north-Norwegian material belongs to <i>O. turgidus</i> (Sars, 1879), described from the Barents Sea and for a long time forgotten. This paper fully illustrates both species, gives a key, ...

The Norwegian population of the Common Guillemot Uria aalge has declined by > 95% since the 1960s, and is classified as critically endangered in the Norwegian Red List. Much of the recent decline has been attributed to reduced food availability, but without extensive documentation of adult diet. Instead, chick diet has been considered a proxy of adult diet during the breeding season in many Norwegian ...
