Die Vegetation des Patscherkofel

Der Arbeitsbereich der vegetationskundlichen Arbeit erstreckt sich von 1500m Seehöhe bis in die Gipfelregion von 2247m des Patscherkofel (Tuxer Alpen). Im Zuge der Geländebegehung wurden nach der Methode von Braun-Blanquet Vegetationsaufnahmen aller wichtigen Vegetationsformen aufgenommen und statistisch (Klassifikation und Ordination) ausgewertet. Auf Basis der numerischen Auswertung wurden die subalpinen und alpinen Vegetationseinheiten pflanzensoziologisch beschrieben

Alpine rivers and their ligneous vegetation with Myricaria germanica and riverine landscape diversity in the Eastern Alps: proposing the Isel river system for the Natura 2000 network. eco.mont (Journal on Protected Mountain Areas Research)|eco.mont Vol. 5 No. 1 5 1|

The setting up of the European network of protected areas (Natura 2000) is nearing completion. Alpine rivers with nearnaturalmorphology and dynamics have become rare and are highly endangered. Myricaria germanica, an endangeredindicator species of Alpine rivers, reflects riverine landscape diversity. The study is based upon an evaluation of literatureas well as upon new data. The analysis of the actual distribution of habitat 3230 Alpine rivers and their ligneous vegetationwith M. germanica identifies the river Isel and its tributaries Schwarzach, Kalserbach and Tauernbach as an importantaddition to the Natura 2000 network

v.in.pygbif - Search and import GBIF species distribution data

The module v.in.pygbif is a wrapper around the pygbif package. Thus, pygbif is a dependency of v.in.pygbif. pygbif can be installed like this: pip install pygbif Through pygbif, the module allows to download data from the Global Biodiversity Information Facility (GBIF) using different search ⁄ filter criteria. Since some of the Darwin Core attribute columns represent SQL key-words, the prefix "g_" was added to all attribute columns. The names of taxa provided at input to the search are written to the column "g_search". The point data is downloaded and projected into the current location. By default import is limited to the current computational region in order to avoid possible projection errors, e.g. when projecting global data into UTM locations. However, in lat⁄lon location this limitation can be skiped using the -r flag. Providing a mask automatically overrides the limitation of the search to the current computational region. Terminology in v.in.pygbif is oriented on the Darwin Core standard: http://rs.tdwg.org/dwc/. Please note that the GBIF Search API has a hard limit of 200,000 occurrences per request. If you want to fetch more records, either subivide your area of interest or split up your search by using different search criteria. When a list of taxa is given as input, v.in.pygbif issues a search for each taxon individually. Thus, in order to split up a search it is recommended to either use different filters on time or space

Study on invasive alien speciesDevelopment of risk assessments to tackle priority species and enhance prevention : final report (and annexes)

Providing evidence-based and scientifically robust risk assessments, as foreseen under Article 5 of the Regulation (EU) 1143/2014 on the prevention and management of the introduction and spread of invasive alien species (IAS), is one step in the process of developing the list of IAS of Union concern. The aim of the current study is to develop such risk assessments alongside evidence on management measures and their implementation cost and cost-effectiveness to help inform policies and prioritise actions. This study includes eight new risk assessments and associated management annexes, for the following species: Bipalium kewense (Kew Flatworm), Cervus nippon (Sika Deer), Cherax destructor (Common Yabby), Delairea odorata (Cape Ivy), Marisa cornuarietis (Colombian Ramshorn Apple Snail), Mulinia lateralis (Dwarf Surf Clam), Obama nungara (Obama Flatworm), and Pycnonotus jocosus (Red-whiskered Bulbul). This study further includes ten risk assessments from previous contracts, revised according to the comments from the Scientific Forum and other stakeholders, concerning the following species: Asterias amurensis (North Pacific Seastar), Axis axis (Axis Deer), Broussonetia papyrifera (Paper Mulberry), Callinectes sapidus (Atlantic Blue Crab), Cortaderia selloana (Pampas Grass), Faxonius immunis (Calico Crayfish), Misgurnus anguillicaudatus (Oriental Weatherfish), Pycnonotus cafer (Red-vented Bulbul), Vespa mandarinia (Asian Giant Hornet), and Xenopus laevis (African Claed Frog). In addition, two risk assessments submitted by a Member State were revised in this contract: Castor canadensis (North American Beaver) and Celastrus orbiculatus (Staff-vine)
