    Asian ring-necked parakeets (Alexandrinus manillensis, formerly Psittacula krameri, hereafter RNP) first bred in Germany in 1969. Since then, RNP numbers increased in all three major German subpopulations (Rhineland, Rhine-Main, Rhine-Neckar) over the period 2003–2018. In the Rhine-Neckar region, the population increased to more than fivefold within only 15 years. Interestingly, there was no significant breeding range expansion of  RNP in the period 2010–2018. In 2018, the total number of RNP in Germany amounted to >16,200 birds. Differences in RNP censuses between years were evident. Surprisingly, cold winters (extreme value, −13.7 °C) and cold weather conditions in the breeding season (coldest month average, −1.36 °C) were not able to explain between-year variation. This finding suggests that in general winter mortality is low – with exceptions for winters 2008/2009 and 2009/2010, and a population-relevant loss of broods is low in our study population. Surprisingly, the social behaviour in terms of spatio-temporal stability of roost sites could well explain positive and negative population trends. Years of spatially stable and regularly used roost sites seem to correlate with increasing population sizes. In contrast, known shifts of RNP among different roost sites or the formations of new roost sites by split are related to population stagnation or a decrease in numbers. Climate change may lead to further range expansion as cities not suitable yet for RNP may become so in the near future.

    A new data infrastructure for family research and demographic analysis: the German Family Demography Panel Study (FReDA)

    This data brief introduces the German Family Demography Panel Study (FReDA; https://www.freda-panel.de/), a longitudinal, multi-actor database for family research. Major substantive fields addressed in the questionnaire include fertility-related attitudes and behaviours, reproductive health, work-family conflict, couples' division of labour, gender roles, intimate relationships, separation and divorce, parenting and intergenerational relations, and well-being. FReDA is based on two initially independent samples: the newly drawn FReDA-GGS sample (n_recruitment = 37,777 respondents, aged 18-49 years), constituting the German contribution to the Generations and Gender Surveys (GGS-II), and the FReDA-pairfam sample (n = 6,216 respondents who originally participated in the German Family Panel [pairfam]). Both samples are fully integrated, using one survey instrument consisting of the harmonized GGS-II and pairfam questionnaires. Mainly web-based interviews, complemented by paper-based interviews, are conducted biannually, with one wave being split across two subwaves. We provide a short description of FReDA's forerunners - the GGS and pairfam - and give an overview of FReDA's design and content, its baseline wave (collected in 2021) and data releases, as well as a brief outlook on FReDA's road ahead

    European Organisation for Research and Treatment of Cancer consensus recommendations for the treatment of mycosis fungoides/Sezary syndrome - Update 2017

    Get PDF
    In order to provide a common standard for the treatment of mycosis fungoides (MF) and Sezary syndrome (SS), the European Organisation for Research and Treatment of Cancer-Cutaneous Lymphoma Task Force (EORTC-CLTF) published in 2006 its consensus recommendations for the stage-adapted selection of management options for these neoplasms. Since then, the understanding of the pathophysiology and epidemiology of MF/SS has advanced, the staging system has been revised, new outcome data have been published and novel treatment options have been introduced. The purpose of the present document is to update the original recommendations bearing in mind that there are still only a limited number of controlled studies to support treatment decisions for MF/SS and that often treatment is determined by institutional experience and availability. This consensus on treatment recommendations was established among the authors through a series of consecutive consultations in writing and a round of discussion. Recommended treatment options are presented according to disease stage, whenever possible categorised into first-and second-line options and supported with levels of evidence as devised by the Oxford Centre for Evidence-Based Medicine (OCEBM). Skin-directed therapies are still the most appropriate option for early-stage MF, and most patients can look forward to a normal life expectancy. For patients with advanced disease, prognosis is still grim, and only for a highly selected subset of patients, prolonged survival can be achieved with allogeneic stem cell transplantation (alloSCT). There is a high need for the development and investigation in controlled clinical trials of treatment options that are based on our increasing understanding of the molecular pathology of MF/SS.

    ISBN 3-9809656-4-3International audienceA Web service has been developed for answering the needs of industry and research for information on solar radiation parameters with a satisfactory quality. It intends to solve the three major problems identified by customers: i) improving access to information, ii) improving knowledge on space and time structure and iii) improving matching of delivered information to actual needs of customers. This service (http://www.soda-is.com) is also innovative with respect to the Internet technologies: it is performing a smart networking of information sources of different natures: databases (radiation, meteorology, elevation, geography...) and algorithms (computation of radiation on slopes, sizing of systems...). These sources were available separately and are geographically dispersed. The service SoDa makes them cooperating and combines them in order to answer to requests, ranging from a series of irradiation values to the sizing of a system

    Forum Geobotanicum 10 (2021/2022)

    No full text
    Forum Geobotanicum is an electronic journal devoted to disseminate information concerning geographical distribution, ecology, morphology, taxonomy and conservation of vascular plants in the European Union with a main focus on middle Europe. It covers from molecular biology to environmental aspects. The focus is to publish original papers, reviews and announcements for the educated generalist as well as the specialist in this broad field. Forum Geobotanicum does not aim to supplant existing paper journals, but will be much more flexible in format, publication time and world-wide distribution than paper journals. Many important studies are being currently published in local journals and booklets and some of them are published privately. Hence, these studies will become aware to only a limited readership. Forum Geobotanicum will encourage authors of such papers to submit them as special issues of the journal. Moreover, the journal is planning to build up an E-mail-address section to support communication between geobotanists in Europe. The editors are optimistic that this electronic journal will develop to a widely used communication forum that will help to stimulate activities in the entire field of geobotany in middle Europe. To overcome problems of long term archivation and effective taxonomic publication of articles published electronically in Forum Geobotanicum, print versions of each volume of the journal and appropriate digital storage devices will be delivered freely to selected university libraries and state libraries in middle Europe.Forum Geobotanicum ist eine elektronische Plattform, deren Zielsetzung darin besteht, neue Erkenntnisse der geobotanischen Forschung in der Europäischen Union mit Schwerpunkt Mitteleuropa umfassend zu verbreiten. Das Journal befasst sich mit allen Fragen von Verbreitung, Ökologie, Morphologie und Taxonomie von Gefäßpflanzen und soll das gesamte Spektrum der Geobotanik von molekularbiologischen Aspekten bis zu Umwelt- und Naturschutzfragen abdecken. Der Hauptfokus liegt auf der Publikation von Originaluntersuchungen und Übersichtsartikeln sowie Behandlung aktueller Fragen des Naturschutzes. Die Zielgruppen sind Personen mit Allgemeinkenntnissen in der Botanik und Floristik sowie Spezialisten auf den Gebieten der Geobotanik und Pflanzensystematik. Das Journal soll keine Zeitschrift in Druckform ersetzen, sondern eine Ergänzung zu den traditionellen Publikationsorganen bilden. Der Vorteil der Zeitschrift liegt in ihrer Flexibilität und raschen Publikationszeit nach Begutachtung der eingereichten Manuskripte und den Möglichkeiten, in größerem Umfang Fotografien und andere Abbildungen zu veröffentlichen. Der Vorteil einer elektronischen Zeitschrift besteht weiterhin darin, dass die Veröffentlichungen weltweit jedermann sofort zugänglich sind. Viele durchaus wichtige Untersuchungen aus dem Bereich der Geobotanik erscheinen in lokalen Publikationsorganen, wie Jahrbüchern und Heimatkalendern, oder auch im Eigenverlag. Da solche Veröffentlichungen bibliographisch kaum erfasst werden, können sie auch nicht in adäquater Weise wahrgenommen werden. Forum Geobotanicum soll ermöglichen, dass auch solche Publikationen in einer Literaturrubrik bekannt gemacht werden und ggf. nach Klärung von Copyright-Fragen als Supplemente der Zeitschrift ins Netz gestellt werden. Forum Geobotanicum nutzt die Vorteile des Internets, indem es abrufbare Hilfen, wie ein Verzeichnis von Adressen, Pflanzenlisten etc. zur Verfügung stellt. Insgesamt soll die Kommunikation zwischen Geobotanikern in Mitteleuropa erleichtert und eine Kommunikationsplattform etabliert werden, die die Aktivitäten auf dem gesamten Wissenschaftsgebiet stimuliert. Das Journal ist uneigennützig und für Autoren und Benutzer kostenfrei. Für die Kostendeckung sind Sponsoren erwünscht, denen eine begrenzte Möglichkeit zur Darstellung eingeräumt werden kann. In der Anfangsphase wird das Journal von einem kleinen Herausgebergremiumbetrieben. Sollte sich Forum Geobotanicum erfolgreich weiter entwickeln, ist an eine Erweiterung des Herausgebergremiums auf Experten aus allen Nationen des mitteleuropäischen Raums gedacht. Um eine langfristige Verfügbarkeit der Publikationen zu gewährleisten, wird jeder Jahrgang von Forum Geobotanicum ausgedruckt, gebunden und mit digitalem Datenträger versehen an ausgewählte Universitätsbibliotheken, Landes- und Staatsbibliotheken Deutschlands und wichtiger Städte Mitteleuropas zur Archivierung und Ausleihe versandt
