new publication: Conservation status of Asian elephants

Our new publication about the drivers of Asian elephant (Elephas maximus) abundance and distribution has been published in Biodiversity and Conservation. The influence of habitat- and governance-related drivers on elephant abundance across the 13 Asian elephant range countries has been analysed. Competing statistical models by integrating a binary index of elephant abundance (IEA) derived from expert knowledge with different predictor variables including habitat, human population, socioeconomics, and governance data were tested.

Special Issue on Remote Sensing training

The special issue on remote sensing training for ecology and conservation is finally out. From the RSEC blog post: Over recent decades remote sensing (RS) has made valuable contributions to ecology and conservation. However, despite its clear value, the potential of RS has not yet been fully realized, and training in the tools and applications for RS is limited. While collection of and access to data are becoming ever cheaper and easier, limited analytical expertise hinders their wider use. Furthermore, the interdisciplinary nature of the research at the interface between remote sensing, ecology and conservation presents its own challenges....

UAV and D-GPS fieldwork in the Steigerwald

First field work of the year and testing the applicability of our UAV and D-GPS in the Steigerwald at the research station of the University Wuerzburg in Fabrik Schleichach. The research station is part of Prof. Jörg Müllers research department, his staff helped us with the field work and Dr. Simon Thorn, the deputy of the research station gave us a tour of the station and the ongoing research. Several methods to locate ground control points were tested as well as the options to launch the UAV in different types of forest. Additionally, we took images of the research station itself and the plots to evaluate its suitability for later field work and courses. Interesting discussions and potential further collaborations with the biologists working on beetles, bird or fungi composition and distribution, as well as forest composition were also part of it. Tobias Ullmann, Hooman Latifi, Christian Büdel and Martin Wegmann conducted the field work and are now planning further field work in spring and summer as well as joint courses around the research...

M.Sc. handed in on animal movement and remote sensing

The M.Sc. thesis “Can animal movement and remote sensing data help to improve conservation efforts?” by Matthias Biber M.Sc. student within the Global Change Ecology program handed in his thesis. He explored the potential of remote sensing data to explain animal movement patterns and if these linkages can help to improve conservation efforts. He used Zebra as study animal in Southern and Eastern Africa. The second supervisor of his M.Sc. was Prof. Thomas Müller from BIK-F.   abstract: Climate and land-use change have a growing influence on the world’s ecosystems, in particular in Africa, and increasingly threaten wildlife. The resulting habitat loss and fragmentation can impede animal movement, which is especially true for migratory species. Ungulate migration has declined in recent years, but its drivers are still unclear. Animal movement and remote sensing data was combined to analyse the influence of  various vegetation and water indices on the habitat selection of migratory plains zebras in Botswana’s Ngamiland. The study area experienced a more or less steady state in normalised difference vegetation index (NDVI) over the last 33 years. More than half of the study area was covered by PAs. NDVI increased stronger in PAs compared to areas that were not protected. NDVI was always higher in the Okavango Delta  compared to the Makgadikgadi Pans. Although zebras are thought to select for areas with high NDVI, they experienced a lower...

AniMove science school – application opened

The next AniMove summerschool will be from August 27th to September 9th 2017. This intense 2 weeks course covers how to analyze animal movement data and environmental remote sensing data for ecological applications. We will cover again the remote sensing and spatial data analysis part and how to combine it with movement tracks. Data access and preprocessing will be taught as well as the derivation of ecological relevant remote sensing products. More details can be found on the course page: 2017 AniMove at...
