Nye opgørelser viser lavere udledning af kvælstof til havet

27.01.2020Der kom mindre kvælstof og fosfor fra de danske vandløb til havet end beskrevet i NOVANA-rapporten ”Vandløb 2018”. En grundig gennemgang af datagrundlag og beregningsmetode har afsløret behov for justeringer, hvorved udledningerne nedjusteres.

BES Annual Meeting, Belfast, Northern Ireland

10.12.2019Emilio Berti, Jakob Assmann, Julia Mata and Scott Jarvie attended the British Ecological Society (BES) Annual Meeting in Belfast, Northern Ireland, from December 10–13. The BES Annual Meeting is Europe’s largest conference dedicated to ecology, which included a packed programme of diverse topics, workshops, Conference Dinner, and networking opportunities. The research presented by the ECOINF and BIOCHANGE members at the BES Meeting included a poster by Julia, and talks by Emilio, Jakob and Scott. We would like to acknowledge the help of collaborators on this research, both within and outside ECOINF and BIOCHANGE, as well as those who provided advice on poster and talk presentations.

Regn, svag vind og høje temperaturer giver fortsat iltsvind i Lillebælt

02.12.2019I forhold til årstiden var der usædvanlig meget iltsvind i det sene efterår. Især det sydlige Lillebælt og de ydre dele af Aabenraa og Flensborg Fjord samt den vestlige del af Ærøbassinet i Det Sydfynske Øhav var i november påvirket af udbredt og intenst iltsvind.

“Restoring global forests and biodiversity” workshop

02.12.2019Forests are key components of the Earth system and they provide a large set of ecosystem services to humanity. Forests are also seen as part of the solution to anthropogenic global warming, with their capacity to be a carbon sink. In the context of United Nations agenda to restore an ecologically damaged planet, it is not thus surprising that forest restoration has sprouted a lot of interest. Current global analysis attempts have been focusing on restoring forest cover to increase the Earth’s carbon sink capacity, but little is known to what extent such efforts could also be accompanied by efforts to halt the mass extinction of species. To address the issue, an international group of 15 researchers with different expertise and perspectives on land science, social sciences and ecological sciences were gathered at BIOCHANGE and ECOINF, during 02-06 December 2019. The workshop, “Restoring global forests and biodiversity”, was intended to analyze, project and write-up how global restoration efforts may have the potential to restore biodiversity in the 21st century. The workshop attendees were from France, Spain, Sweden, the USA, China, Netherlands, and South Africa, together with BIOCHANGE & ECOINF researchers (Alejandro Ordonez, Jens-Christian Svenning, Robert Buitenwerf, Pep Serra-Diaz, Signe Normand, and Wenyong Guo). During the workshop, we discussed the framework of the proposed project, put together many available data, and prepared some initial analyses. It was a very productive, informative and fun workshop. We are looking forward to the output from the workshop. Text by Wenyong Guo

Danske ulve er hovedsageligt nataktive

26.11.2019Af: Peter Sunde og Kent Olsen Vildtkameraer brugt til at bestandsovervåge ulve, sladrer også om, hvornår på døgnet ulvene er mest aktive. Og det er de når det er mørkt – året rundt. Ulve fotograferes syv gange så hyppigt per time fra kl. 20 aften til kl. 08 morgen end fra kl. 10-18, hvor de hviler. Hvalpe fotograferes oftere i dagslys end voksne ulve. Udpræget nataktivitet hos ulve er formentlig en tilpasning til at undgå mennesker. Dette viser en ny forskningsartikel i tidsskriftet Flora & Fauna

19th International Winter School

24.11.2019Candice Power participated in the Wood Anatomy and Tree Ring Ecology course as part of The Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) 19th International Winter School from November 24-30th. The course took place in Klosters Dorf, Switzerland. The course, taught by Holger Gartner, Alan Crivellaro, and Fritz Schweingruber, included lectures on a wide range of topics on wood anatomy including learning how to identify tree species based on microscopic traits and determining factors influencing wood traits including presence of resin ducts, tension/compression wood, and false rings, as well as ring width and vessel size. There was also a lot of time for practical work where Candice learned how to make microsections of her samples from Greenland using a sledge microtome.  Excursions included a presentation at the WSL Institute for Snow and Avalanche Research in Davos and a visit to the Nutli-Huschi Folk Museum.
