The Nordic Greylag Goose (Anser anser) Project.

Neck-banding of Greylag Geese in the Nordic countries was initiated in 1984 bythe Nordic Council for Wildlife Research as there was a need for a thorough knowledge of various aspects of the population ecology and migration patterns of the populations in different parts of the four countries. Since the start in 1984 more than 6400 Greylag Geese have been neck-banded, yielding more than 250,000 read

Forty years of midwinter Counts of waterfowl along the Coasts of Scania, South Sweden.

The International Midwinter Counts, organised byWetlands International, started in January 1967, butco-ordinated counts were organised along the coastsof Scania, south Sweden, already since January 1964.This paper summarises the results of the first fortyyears. During the first years full coverage was attained,but in later years the counts covered nine larger areas,containing about 75% of all wate

Wintering diving duck populations in the Öresund, Southern Sweden, in relation to available food Resources.

Intensive surveys of staging and wintering diving ducks in the Öresund area,southern Sweden, were undertaken during the winters 1995/96, 1996/97 and1997/98 as a part of the Environmental Impact Assessment (EIA) related to theestablishment of a Fixed Link (bridge–tunnel–artificial island) between Swedenand Denmark. Monitoring of the benthic fauna made it possible to compare thecalculated food requi

Incidence and familial risk of pleural mesothelioma in Sweden : A national cohort study

Familial clustering of pleural mesothelioma was reported previously, but none of the reports quantified the familial risk of mesothelioma or the association with other cancers. The contributions of shared environmental or genetic factors to the aggregation of mesothelioma were unknown. We used a number of Swedish registers, including the Swedish Multigeneration Register and the Swedish Cancer Regi

Long-term trends and Changes in numbers and distribution of some wintering waterfowl species along the Swedish Baltic coast.

Regular counts of wintering waterfowl have been undertaken as a part of the International Waterfowl Census (IWC) and the National Swedish Environmental Monitoring Program since 1964. After the first years, a network of annually surveyed sites was established for the calculation of annual indices. Country-wide surveys (also including aerial counts) were undertaken 1971–1974, 1987–1989, 1992–1993 (p

Wintering Swans Cygnus spp. and Coot Fulica atra in the Öresund, South Sweden, in relation to available food Resources.

In connection with the building of a Fixed Link (bridge –artificial island – tunnel) between Sweden and Denmarkintensive studies of waterfowl and benthic fauna and florain the Öresund were undertaken as a part of the EnvironmentalImpact Assessment Study. This paper analysisthe occurrences of staging and wintering herbivores (i.e.Mute Swan Cygnus olor and Coot Fulica atra) in relationto available f

Why should Greylag Goose Anser anser parents rear offspring of others?

The benefits and costs of rearing large broods were studied in a population of neck collared Greylag Geese in Scania, southernmost Sweden. Families were divided into four groups according to brood size: 1-4, 5-8, 9-12 and >12 young. Gosling survival showed a significant positive relationship with brood size on arrival at the rearing area. First-year and third-year local survival, as well as breedi

Field choice in spring and breeding performance of Greylag Geese Anser anser in Southern Sweden.

Selection and exploitation of feeding areas by pre-breeding and nonbreeding Greylag Geese A nser anser, as we ll as by families, was studied in a breeding area consisting of four lakes in Scania, southernmost Sweden, in the years 1997-2000. Total production of young in each lake as we ll as the breeding performance of neck collared individuals was established annually, 1985-2000. This breeding pop

Submerged vegetation and the variation in the autumn waterfowl Community at lake Tåkern, Southern Sweden.

We analysed data from 25 years of standardised mid-September counts of waterfowl at eutrophic Lake Tåkern, southern Sweden. For eight species, counts were compared with a national index constructed from similar counts at numerous lakes and coastal sites. For Crested Grebes and Mute Swans there was a correlation between counts at Lake Tåkern and the national index, suggesting that they simultaneous

Ergodicity of age-dependent inventory control systems

We consider continuous review inventory systems with general doubly stochastic Poisson demand. In this specific case the demand rate, experienced by the system, varies as a function of the age of the oldest unit in the system. It is known that the stationary distributions of the ages in such models often have a strikingly simple form. In particular, they exhibit a typical feature of a Poisson proc

Change of mate in a Greylag Goose Anser anser population effects of timing on reproductive success

The population of the West Baltic Greylag Goose Anser anser is migratory,breeding in southwest Scania, southernmost Sweden and wintering in theGuadalquivir Marismas, southwest Spain, or in the Dutch Delta. This populationhas been the subject of a long-term study o f a sample o f neck cottaredindividuals, and observations o f marked individuals were used to assessrates of mate fid e lity in this su

Fine and ultrafine particle exposure: Health effects and biomarkers

Particle, especially fine and ultrafine particle exposure has been linked to lower airway infections, asthma, chronic obstructive pulmonary disease (COPD), ischemic heart disease, stroke and cancer. The underlying mechanisms are under active investigation, and are still not fully understood. Several mechanisms have been proposed such as oxidative stress, inflammatory response and genotoxicity.Diff

The Drivers of Long-run CO₂ emissions in Europe, North America and Japan since 1800

Using an extended Kaya decomposition, we identify the drivers of long-run CO₂ emissions since 1800 for Denmark, France, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, the UK, the United States, Canada and Japan. By considering biomass and carbon-free energy sources along with fossil fuels, we are able to shed light on the effects of past and present energy transitions on CO₂ emissions.

Bone mineral crystal size and organization vary across mature rat bone cortex

The macro- and micro-features of bone can be assessed by using imaging methods. However, nano- and molecular features require more detailed characterization, such as use of e.g., vibrational spectroscopy and X-ray scattering. Nano- and molecular features also affect the mechanical competence of bone tissue. The aim of the present study was to reveal the effects of mineralization and its alteration

Production and use of regional climate model projections – A Swedish perspective on building climate services

We describe the process of building a climate service centred on regional climate model results from the Rossby Centre regional climate model RCA4. The climate service has as its central facility a web service provided by the Swedish Meteorological and Hydrological Institute where users can get an idea of various aspects of climate change from a suite of maps, diagrams, explaining texts and user g

Full Scale Firefighting Tests in the Tistbrottet Mine

The paper describes full-scale fire-fighting tests performed in an underground mine. A total of six different methods to fight a full scale fire in a mine tunnel were tested. The methods involved different fire-fighting equipment but were comparable regarding fundamental conditions such as length of response-route, fire-fighting set-up, and smoke and fire size. The aim was to compare different equ
