Putting digital innovation hubs into regional context : a European survey

While digitalisation is oftentimes thought of as a global megatrend and something that transcends national borders and geographical distances, it is at the same time a very tangible process exhibiting considerable regional and sectoral variation. Against this backdrop, Digital Innovation Hubs (DIHs) (a policy initiative in the context of the Digitising European Industry (DEI) strategy of the EU) c

A LEAP Forward in Wildlife Conservation : A Standardized Framework to Determine Mortality Causes in Large GPS-Tagged Birds

Anthropogenic activities threaten many wildlife populations by increasing mortality rates, making it crucial to identify the locations and causes of mortality to inform conservation actions. Technological advancements, such as GPS satellite tracking, enable precise recording of wildlife movements. High-resolution data from such devices can facilitate rapid carcass recovery and provide insights int

Gone West : Revisiting the Cuneiform Tablet of Thunder-Rolling-Down-the-Mountain

For all its physical modesty, a small administrative cuneiform tablet currently in the collections of the West Point Museum, part of the U.S. Army Center of Military History and located at the United States Military Academy at West Point, NY, has become quite the celebrity in numerous online fora and blog posts, being presented as evidence of cultural relations between the Old World and the New pr

Effect of geomagnetic field on orientation of the marsh warbler, Acrocephalus palustris, in Sweden and Kenya

The orientation of juvenile marsh warblers during autumn migration was investigated at two widely different latitudes, in Sweden and in Kenya, by cage experiments in manipulated magnetic fields during the twilight period after sunset. The objective was to compare responses by birds exposed to different geomagnetic conditions, particularly to the shift in magnetic inclination between the northern a

A voyage to Africa by Mr Swift

A male common swift Apus apus was equipped with a light logger on August 5, 2010, and again captured in his nest 298 days later. The data stored in the light logger enables analysis of the fascinating travel it made in this time period. The state of the art algorithm for geolocation based on light loggers consists in computing first sunrise and sunset from the logged data, which are then converted

La Renne

The exhibition is the fruit of a discussion that begun in 2015 with Etienne Bernard, director of the Frac Bretagne and curator of the exhibition, is intended to be an important step in his career.It will constitute a form of retrospective of Værslevs entire production over the past 15 years. The artist will present a new series that will serve as a “re-reading rail” for his older series. Thus, the

Louise Lawler / Fredrik Værslev

Indipendenza Roma is proud to present Louise Lawler / Fredrik Værslev, a two-person exhibition that responds directly to our unique spaces to explore the tension between an artwork and its surrounding architectural context, spurring questions of taste, value, function, and decoration.

Seasonal distributions of Caspian Terns Hydroprogne caspia from Swedish populations, revealed by recoveries and resightings of ringed birds

The aim of this study was, by analysing recoveries and resightings of Caspian Terns Hydroprogne caspia ringed in Sweden, (1) to identify areas of importance during their migration and wintering, (2) to investigate the annual routines of migration and wintering of different age categories, and (3) to investigate how human activities, especially shooting, have affected survival of Caspian Terns over

Bird orientation : Displacement experiments with young autumn migrating wheatears, Oenanthe oenanthe, along the Arctic coast of Russia

Migratory naive birds are thought to find the migration route from their natal site to a specific wintering area by either clock-and-compass orientation or goal area navigation. These two alternative hypotheses were tested by extensive longitudinal displacements of juvenile wheatears, hatched in northeastern Siberia, on their first autumn migration towards the wintering area in East Africa. Orient

An Implantable, Low-Power Instrumentation for the Long Term Monitoring of the Sleep of Animals under Natural Conditions

Sleep is a universal and complex state and it is widely agreed that this state is present in every animal species. However, the evolutionary origins of sleep remain ignored or misunderstood, which has led researchers to study, in various species, this common behaviour of all living organisms. Sleep is commonly studied at various levels under laboratory conditions, using tethered devices which reco

Examining the limits of flight and orientation performance : Satellite tracking of brent geese migrating across the Greenland ice-cap

Brent geese, Branta bernicia hrota, were equipped with satellite transmitters on a spring stop-over site in Iceland. The brent geese deposit heavy fuel reserves for long-distance flights across the high Greenland ice-cap to breeding destinations in north Canada. Satellite tracking of brent geese on this journey serves the twofold purpose of testing specific predictions about: (i) size-dependent po

Stopover and fat accumulation in passerine birds in autumn at Ottenby, southeastern Sweden

Stopover duration and fat accumulation were studied during autumn migration at two sites near Ottenby, Oland, SE Sweden in 1985 and 1986. Post juvenile moult was scored on juvenile birds. In several of the species fat class and body mass increased with day of season (thrush nightingale Luscinia luscinia, barred warbler Sylvia nisoria, and whitethroat S. communis), while in the lesser whitethroat S

Migratory flights of Arctic geese tracked by satellite

Brent Geese migrating in spring towards Arctic Canada have been tracked by satellite from Iceland to the Davis Strait. Length and direction of the stages were adapted to the geographic features and hospitability of the areas crossed; the ice-cap of Greenland was overflown in its southern part.

Comparative orientation experiments with different species of passerine long-distance migrants : Effect of magnetic field manipulation

The orientation of four species of passerine long-distance migrants was studied in spring and autumn by orientation cage experiments during the twilight period after sunset in Sweden. Two groups of migrants from the Palaearctic-African migration system were used: migrants wintering mainly north of the magnetic equator in west Africa (pied flycatcher, Ficedula hypoleuca, and redstart, Phoenicurus p

Springtime migratory restlessness and departure orientation of great knots (Calidris tenuirostris) in the south compared to the north yellow sea

Background: The motivation of birds to proceed with migration is associated with both endogenous and exogenous factors. According to their migratory situation and to the characteristics of stopover sites, birds might exhibit migratory motivation differently among sites. Although migratory motivation of migrating birds has been well stud-ied in many species, the investigation of the same species in

Proximate causes of avian protandry differ between subspecies with contrasting migration challenges

In many migratory birds, males precede females during migration and arrival at the breeding sites. Three proximate mechanisms are proposed to explain this phenomenon of protandry: males 1) winter closer to breeding sites, 2) start spring migration earlier, and/or 3) migrate faster than females. So far, the relative contribution of these mechanisms to protandry is unknown. The present study investi
