Sharing experiences on conservation of Lesser horseshoe bats Rhinolophus hipposideros

April 23, 2018

On 20. – 21.4.2018, there was a final conference of the Polish Life+ project »Podkowiec« (http://podkowiecplus.pl/en/home-page/) in Bochnia in Poland. On invitation of the organisers, Maja Zagmajster presented the experiences from the Life+ project »Life at night«, with special focus on work and results related to bats. This project, where University of Ljubljana was one of the partners, was conducted in 2010-2014, and aimed at finding solutions to lower the negative impact of light pollution on bats and moths. (LINK)

Seminar »Conservation of communities of aquatic ecosystems«

March 28, 2018

On Saturday, 24.3.2018, we participated at the seminar »Conservation of communities of aquatic ecosystems« for teachers of elementary and secondary schools, to introduce them to the specifics and wonders of subterranean life. The seminar was held at the Nature reserve Škocjanski zatok (http://www.skocjanski-zatok.org/), and organised by Park Škocjanske jame (http://www.park-skocjanske-jame.si/) and National Education Institute Slovenia (https://www.zrss.si/en/). The speakers came from two research groups of Department of Biology of Biotechnical faculty University of Ljubljana, namely SubBioLab (1,3) and Group for functional morphology of animals and developmental biology (2; see page: http://www.anguinus.net). The following themes were presented:

(1) Assist. Prof. Dr. Maja Zagmajster: Caves – subterranean wetlands

(2) Prof. dr. Rok Kostanjšek: Biology of the olm

(3) Assist. Prof. Dr. Simona Prevorčnik: Interstitial waters – overlooked subterranean habitat

Conservation genetics of olm (Proteus anguinus)

February 9, 2018

On Thuesday, 27. 2. 2018, Valerija Zakšek had a lecture about our research on the conservation genetics of proteus. Proteus is charismatic cave animal and endemic species of the Dinaric Karst. It is of extraordinary importance for protection of subterranean waters. Here, we presented main results of the conservation genetic research conducted within an applied research project under the title “Toward the conservation of the European cave salamander (Proteus anguinus): monitoring guidelines, current status estimation and identification of evolutionarily significant units” (project leader: Peter Trontelj). 

Lecture was organised by Society for cave exploration Ljubljana.

Collective field trip – sampling interstitial fauna in an emptied accumulation lake

January 27, 2018

On 24th and 25th of January, we went on a field trip.  Every 20 years, the dam on Soča river is fully opened and accumulation lake emptied for maintenance purposes. We seized the opportunity and sampled intersticial fauna above and below the dam. Enormous quantities of sludge were washed away and the river showed us its face as it once was, with canjons, meanders and gravel bars.  Just below the upper layer of gravel, the smell of hydrogen sulfide and fine, cement-like sediments confirmed our predictions: not the best conditions for interstitial fauna.

Lecture: Amphipods of Switzerland

December 4, 2017

On Wednesday (29. 11. 2017) Roman Alther, a PhD student in Florian Altermatt’s lab at Eawag (Swiss Federal Institute of Aquatic Science and Technology) and University of Zurich, gave us a presentation of his work on the diversity and distribution of  amphipods in Switzerland.

Abstract

Biodiversity patterns and biological communities are strongly influenced by habitat connectivity. The structure of such spatial networks may shape both dispersal of native species but also invasions of non-native species, and can result in characteristic diversity patterns. Fluvial networks offer unique possibilities to study such processes in a spatially explicit manner. Worldwide, rivers are strongly affected by non-native species that often have detrimental effects on natural communities.

I studied the spatial imprint of the network structure on the community composition of native and non-native amphipod species in the upper river Rhine basin. My analyses revealed distinct patterns of local species richness in the network and specific differences in distribution of native and non-native species. Specifically, non-native species are still mostly restricted to larger and more connected streams whereas small and more isolated headwaters present refugium habitats for native species. Furthermore, overall amphipod community structure closely mirrored the topological modularity of the network, highlighting the network’s imprint on community structure. These results improve the understanding of the influence of spatial connectivity on biodiversity and invasion processes in natural systems.

Scientists from Department of Biology of University of Ljubljana and Notranjska Museum Postojna received the Alexander von Humboldt Gedächtnispreis Memorial Award

November 29, 2017

2017 Alexander von Humboldt’s Memorial Award for the best scientific paper published in Senckenberg’s journals was received by the Slovenian speleobiologist from Biology Department of Biotechnical Faculty of University of Ljubljana and Notranjska Museum Postojna.

Senckenberg Gesellschaft für Naturforschung was founded on Johann Wolfgang von Goethe’s initiative in 1817. Nowadays it includes six research institutes and three natural museums, and is one of the largest and oldest natural history associations in Europe. Senckenberg publishes nine scientific journals covering wide range of research fields, including biodiversity, marine biology, evolution and paleontology, and presents annual reward for the best scientific paper published herein. This year’s award was the 25th annual Alexander von Humboldt’s Memorial Award.

The award was presented by the Association’s director Prof. Dr. Volker Mosbrugger in Frankufurt on Monday, 27. November, to Slovenian speleobiologists Slavko Polak, Teo Delić, Rok Kostanjšek and Peter Trontelj for the following research article „Molecular phylogeny of the cave beetle genus Hadesia (Coleoptera: Leiodidae: Cholevinae: Leptodirini), with a description of a new species from Montenegro“, published in Arthropod Systematics & Phylogeny 74(3): 241–254.

The publication deals with the molecular phylogeny of the highly specialised hygropetricolous cave beetles of the genus Hadesia, and a description of new species from Montenegro, Hadesia zetae. The Award’s jury was convinced by the atractivness of the research object itself as well as by the use of the integrative approach, combining results of morphological analyses,  molecular phylogeny and biogeography, as well as presenting a need for the conservation of the subterranean habitats.

Each of us should be the guardian of waters

October 26, 2017

On 14th October, the article on importance of protecting the groundwaters, especially as source of drinking waters, was published in Slovenian magazine »Večer«. The article presents various aspects important for protecting the groundwaters. Special place is given also to presenting the importance of subterranean fauna, especially related to groundwaters.

…and about poaching in caves

June 8, 2016

In past few months, illegal traps for cave beetles were found in several caves. So far, we declared beetle traps from five caves, the problem was now reported also in popular media (in Slovene):
