Re-introduction and present status of the lynx (Lynx Lynx) in Switzerland
Urs Breitenmoser,Christine Breitenmoser-Würsten,Simon Capt
Hystrix : the Italian Journal of Mammalogy , 1998, DOI: 10.4404/hystrix-10.1-4118
Abstract: A lynx recovery programme started in Switzerland in 1970. From 1970-76, at least 14 lynx were translocated from the Carpathian Mountains into the Swiss Alps. Another re-introduction took place in the Jura Mountains, but no corridors exist as a connection between these two popula- tions in Switzerland. The development of the populations was not monitored at first. In 1980 systematic research was initiated, which gradually evolved into the Swiss Lynx Project. Not all releases were successful, but the re-introduction in the northern and western Alps founded a population that covered an area of some 4000 km2 in 1981. In the western Swiss Alps, lynx moved into Italian and French territory. Towards the eastern Swiss Alps, the expansion was slower and ceased about ten years ago. During the last five years, there even has been a reduction of the area occupied. Today, the population covers an area of about 10000 km2 in the Swiss Alps, of which 50% is suitable lynx habitat. Based on size and overlap of average home ranges of radio-tagged lynx, the population was estimated to include some 50 adult residents. At present, the growth rate of the population appears to be too low to allow a further expansion in range. It is uncertain whether recruitment is sufficient to compensate for the high losses among resident adults induced by traffic accidents and illegal killing.
The re-introduction of the lynx in Slovenia and its present status in Slovenia and Croatia

Hystrix : the Italian Journal of Mammalogy , 1998, DOI: 10.4404/hystrix-10.1-4123
Abstract: The lynx disappeared from Slovenia and Croatia at the beginning of the 20th century. In 1973, six lynx from the Slovakian Carpathian Mountains were translocated to Kocevje in southern Slovenia. In this densely forested region where prey animals are plentiful, a core population developed immediately and spread over Slovenia and Croatia. In 1984 the first lynx reached the Julian Alps and crossed over to Italy. The population increased so fast that already in 1978, hunting of lynx was legalised. From 1978 to the present, a total of 229 individuals were hunted, another 48 deaths from other reasons are also known. The intense harvest hindered further expansion of the population, especially the re-colonisation of the Alps. In recent years the hunting season and the hunting quota were reduced, and in Slovenia hunting is now restricted to the core area of the population.
Present status and distribution of the Lynx in the Swiss Alps

Hystrix : the Italian Journal of Mammalogy , 2001, DOI: 10.4404/hystrix-12.2-4174
Abstract: To evaluate the population trend of lynx in the Swiss Alps, we analysed the spatial and numerical development of signs of presence found from 1995 to 1999 and compared them with previous years. Three sources of information on the presence of lynx are available: (1) reports of lynx killed or found dead; (2) records of livestock killed by lynx; (3) records of wild prey remains, tracks, scats, sightings, and vocalisations. We distinguished three levels of reliability: Quality 1 represent the hard facts, e.g. all reports of lynx killed or found dead, photographs of lynx as well as young orphaned lynx caught in the wild and taken into captivity. Quality 2 include all records of livestock killed, wild prey remains, tracks and scats reported by people who have attended special courses, e.g. mainly game wardens. Quality 3 are all wild prey remains and tracks reported by the general public as well as all sightings, scats and vocalisations, e.g. signs that cannot be verified. More than 1600 signs of presence were recorded in the Swiss Alps in this 5-year-period. A high number of quality 1 and 2 records showed that (1) the lynx population in the north-western Swiss Alps increased from 1994 to 1999, that (2) there is a moderate presence of the species in the central and south-western parts and (3) none or hardly any lynx are found in the eastern Alps of Switzerland. Based on a radio-telemetry study and the number of quality 2 data, we were able to estimate the number of lynx in the Swiss Alps at 70 individuals. To counterpart the uneven distribution of lynx in Switzerland, lynx are being translocated from the north-western Alps to the eastern Swiss Alps, as the expansion of the Swiss lynx population is crucial for the conservation of the lynx in the whole Alps.
Modelling the Species Distribution of Flat-Headed Cats (Prionailurus planiceps), an Endangered South-East Asian Small Felid

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0009612
Abstract: The flat-headed cat (Prionailurus planiceps) is one of the world's least known, highly threatened felids with a distribution restricted to tropical lowland rainforests in Peninsular Thailand/Malaysia, Borneo and Sumatra. Throughout its geographic range large-scale anthropogenic transformation processes, including the pollution of fresh-water river systems and landscape fragmentation, raise concerns regarding its conservation status. Despite an increasing number of camera-trapping field surveys for carnivores in South-East Asia during the past two decades, few of these studies recorded the flat-headed cat.

Journalistikkens rolle i netv rkssamfundet

Journalistica : Tidskrift f?r Forskning i Journalistik , 2007,
Abstract: In the network society the boundaries between media, politics, economy and culture is put under pressure. The media is placed in an increasingly direct competition with the state, private companies, interest organisations etc. about the powers of definition within important spheres of society. This is illustrated by for instance “the Muhammad crisis” and the debate about the documentary “The secret war”. Both cases also show the importance of the legitimacy of the roles played by the media in the network society. This puts forward the old question about the objectivity of journalism, and makes this question important in the debate about the roles of journalism in the network society.
Europ isk offentlighed i danske medier – Danmark som foregangsland for udviklingen af en transnational politisk journalistik?

Journalistica : Tidskrift f?r Forskning i Journalistik , 2006,
Abstract: This article focuses on the Europeanization of the Danish news media. Europeanization of media content refers to two central criteria: a) an increased focus on European themes and actors, and b) an evaluation of theses themes and actors from a connation state dominated point of view. According to such criteria, recent studies across Europe, have documented a significant level of overall Europeanization of Danish media at the level of media content. This article compares the results of some of the most recent studies of Europeanization and tries to answer the question of what makes Denmark a best-case example, when it comes to Europeanization of the news media.

Comment on 'Anomalous diffusion induced by enhancement of memory'
Rüdiger Kürsten
Physics , 2015,
Abstract: In a recent paper [2] the author introduced and investigated a random walk model similar to a model introduced in [1]. In these models the increment of the random walk depends on the complete past of the process. In this note I will point out that the models considered in [1] and [2] can be mapped onto each other one to one. They can be defined on a common probability space and hence all expectation values of the model [2] with parameter p are equal to the ones of [1] with a corresponding parameter $\tilde{p}$.
