From basic everyday foraging behaviors to extraordinary long-distance migrations: animal movements are important for species survival, ecosystem functioning, and biodiversity. My research bridges across theoretical and applied aspects of movement ecology, from the behavioral underpinnings and social interactions to ecosystem functions and macro-ecological patterns. I am particular interested in studying the exceptional challenges that an increasing human footprint poses for movements of wildlife, which ultimately leads to the question of human wildlife coexistence. To that end, I pursue an integrated social-ecological research program to better understand human wildlife interactions and develop sustainable conservation recommendations.

The conservation of large mammals, and large carnivores in particular, requires integrative perspectives ranging from genetics, population and movement ecology to understand their ecology, as well as psychology, social and political sciences to address potential conflicts with human societies. Research on social-ecological systems provides frameworks to bring these formerly separate scientific domains together and find solutions for human-wildlife coexistence.
My DFG-funded PhD project with Prof. K. Böhning-Gaese focused on wildlife tourism as a cultural ecosystem service, with a specific emphasis on large mammal diversity in four protected areas of Southern Africa (Etosha National Park, Chobe National Park, Kruger National Park and Hluhluwe-Imfolozi Park).
My current Senckenberg Postdoc project focusses on the social-ecological implications of the wolf (Canis lupus) returning to Germany. I use methods from ecological and social sciences to understand how wolves and people can coexist in human-dominated landscapes, and hopefully provide solutions for long-term and sustainable coexistence. The Leibniz-funded Transfer Project KnowWolf “Transfer of evidence-based and co-produced Knowledge for Human-Wolf Coexistence” (3 years), aims at reducing the gap between Science and Society on the topic of human-wolf coexistence, across borders.
Within the DFG-funded Kili-SES Research Unit, I investigate which biodiversity components underpin non-material nature’s contributions to people, by linking biodiversity data collected on Kilimanjaro’s southern slopes, and societal demands from multiple stakeholders groups.

My research interests focus on habitat selection and movement ecology of large mammalian herbivores. I am studying their long-distance movement behaviour and the effect of infrastructure-driven development on these movements in desert, semi-desert and steppe ecosystems in Mongolia. Mongolia has some of the largest remaining grassland and desert ecosystems that are critical habitat for khulan (Equus hemionus), goitered gazelles (Gazella subgutturosa) and Mongolian gazelles (Procapra gutturosa). In the past decade, however, large-scale mining projects for coal, copper and gold as well as infrastructure-based economic development projects have emerged in Mongolia’s drylands. These developments often pose barriers to animal movements and threaten their survival. I aim to better understand how mammalian herbivores react to barriers and how the detrimental effects of anthropgenic develoments in one of the last big migration systems can be mitigated.

My main research interest is the conservation of animal species and populations, with a strong focus on social, ecological, and genetic aspects of range shift and range (re )expansion. In particular, I am aiming at the development of integrative conservation strategies. During my PhD, I investigated ecological and genetic factors determining re-colonization success of a protected bat species in Central Germany, closely collaborating with local NGOs (Interessengemeinschaft Fledermausschutz und –forschung Thüringen e.V.) and both local and international research institutions (Nachtaktiv – Biologen für Fledermausforschung, Erfurt, Germany; INRA, Rennes, France). My current Senckenberg Postdoc project is directed at conservation challenges associated with the grey wolf (Canis lupus) recolonizing human dominated regions in Germany and other European countries. In particular, I seek to elucidate individual and cultural factors shaping human perception of and attitudes towards wildlife, especially wolves. Because perceptions and attitudes may depend greatly on knowledge, one objective is to identify and overcome barriers to knowledge transfer and close the gap between science and society. For this purpose, I am developing a tablet application for horizontal knowledge transfer in the framework of the Leibniz-funded project KnowWolf (“Transfer of evidence-based and co-produced Knowledge for Human-Wolf Coexistence”). Social and natural scientists, local wolf information centers, museums, and other public institutions collaborate within this project to maximize the outreach, impact, and sustainability of wolf conservation efforts.

I am a behavioral ecologist who studies how animals to cope with environmental changes resulting from human activities. My research has primarily focused on phenotypic integration between behavior and other components of the phenotype (morphology, physiology, life-history) to understand the ecology and evolution of populations. I have investigated these topics by focusing on how environmental stressors (contaminant, diet quality and availability) affect the magnitude of phenotypic integration and used quantitative genetic approaches to compare patterns of integration among populations and sexes. Within the Movement Ecology group and the Nature 4.0 project, I will use automated tracking technologies to characterize variation in movement patterns of forest birds and will link this variation to broader ecosystem functions (predation and herbivory regulation).

My PhD research on the spatial and movement ecology of giraffe, with a special focus on the reticulated giraffe (Giraffa reticulata). Using aerial and tracking data to understand the factors driving giraffe habitat occupancy, preferences, seasonal movements, and co-existence dynamics with humans and livestock. In addition to forwarding giraffe science, we hope this research will inform giraffe conservation and land protection decisions and community-led conservation efforts.
I am based in San Diego, California, USA where I am employed as a researcher with the San Diego Zoo Institute for Conservation Research, where in addition to co-leading the collaborative community based Twiga Walinzi reticulated giraffe conservation and multi-disciplinary socio-ecological research program in northern Kenya, I am also involved in leopard (Panthera pardus) and savannah elephant (Loxodonta africana) conservation and research. I work in SE Asia as part of a team with local partners on research to address the illegal wildlife trade in bears and bear parts, saiga horn and tiger parts, as well beginning to developing research to inform a potential Asiatic black bear (Ursus thibetanus) rewilding effort in northern Laos. More recently, we have been supporting new research on former working elephants in Myanmar for possible re-introduction. Lastly I support saiga (Saiga tatarica) conservation and education efforts in Uzbekistan and southern Russia. I am a member of the IUCN Giraffe and Okapi Specialist Group, and the IUCN Bear Specialist Group.

Currently I am studying the migratory behaviour of Whooping Cranes in the eastern and mid-western USA. Specifically, I aim to understand how migration behaviour develops in the young years of those long-lived, social birds. There are only two wild migratory populations of whooping cranes left in existence, one breeding in Alberta/Canada and wintering in northern Texas, while the other one was introduced to Wisconsin by conservationists at the beginning of this century, in an attempt to restore crane populations in areas where they once have been extirpated. Using movement data obtained from GPS-tracked birds, I will attempt to analyse and compare migration patterns of crane individuals from both populations, and study how they change as the birds mature. Previously, I studied the occurrence of ticks (Ixodida) in recreational areas around the city of Karlsruhe (Germany) and how their presence can be linked to environmental factors like temperature, humidity and vegetation density.
I have a strong interest in wildlife biology, behavioral ecology and conservation of large mammals and especially of large carnivores. I am based at the LUPUS Institute – the German Institute for Wolf monitoring and research which I co-founded together with my colleague Gesa Kluth. Since 2002 I am scientifically following and documenting the recovery of wolves in Germany. With this PhD study at the movement ecology group in Frankfurt I aim to give a profound scientific description of the population recovery, especially on the re-colonization process of wolves in Germany, the dispersal and pack formation of this new population, and on the territory size, movement and activity of wolves in the highly human dominated landscape of Germany. The study will hopefully contribute to a better understanding of this controversial carnivore. I am a member of the Large Carnivore Initiative for Europe (www.lcie.org), a species specialist group of the IUCN.

My research interest is in conservation biology and how we can use math and modeling to make better decisions regarding conservation. While studying my master’s degree I used bog turtles (Glyptemys muhlenbergii) as a case study for how we can resource-efficiently locate and survey rare and elusive species. This work combined species distribution modeling and intensive field work in close collaboration with state wildlife agencies in the United States to give me first-hand experience into what it means to conserve species at ground-level. For my Ph. D. I am changing my focus to examine how movement affects population dynamics in highly mobile animals. My study system is the Eastern Steppe of Mongolia and the nomadic Mongolian Gazelles (Procapra gutturosa). I will simulate this system by programming an herbivore-vegetation model. To do this I am combining expertise from the two working groups I am involved in. I am a part of Thomas Müller’s group, whose focus is on movement ecology and conservation, and Thomas Hickler’s group, whose focus is on vegetation modeling and effects of climate change. We hope this modeling approach will help us better understand how important mobility is to long-term population persistence of animals living in unpredictable and dynamic landscapes.

My work is part of the BMBF project MoreStep which brings together social and ecological sciences to identify societal drivers that can lead to an ecological tipping point of the Mongolian steppe ecosystem. Our role is to use the herbivore-vegetation model to examine the importance of movement in maintaining sustainable numbers of wild and domestic herbivores. The model will also be used to disentangle the effects of climate and grazing on vegetation.

How can we find a way to have people and wildlife coexisting in a peaceful and structured way? Many of today´s challenges we experience are complex and multicausal. This is why I am very interested in combining different fields of research to find solutions with an interdisciplinary approach.
I am currently completing my Bachelor in Biological Sciences by doing my Bachelor Thesis at SBiK-F. The topic I am working on is the return of the wolves in Germany and public perceptions. This includes the evaluation of human emotional responses to wolves in different situations, using a social survey. The long term aim is to obtain a better understanding of the role emotions in conflicts involving human-wolf interactions. In my further studies I want to learn more about the different approaches to sustainability.
Having a broad interest in the behaviour and conservation of large mammals, I am especially interested in the related human-wildlife conflicts being current topics not only in science but in politics and society as well. One of the most recent issues in Germany is the return of wolves. For my Master Thesis, I am working at SBiK-F and conduct a media analysis concerning wolves in Germany to better understand how the shaping of information influences public perception on this topic. In this the focus is set on the relationships between emotions and stakeholders as depicted in online and printed newspaper articles which have been published since wolves‘ return in 2000 until 2018.
I did my Bachelor at the Goethe Universität in Frankfurt working with the movement and behaviour of giraffe, zebra, impala and wildebeest in a shared enclosure in the Opel Zoo and moved to the Christian Albrechts Universität zu Kiel to pursue my Master studies.

My research is at the interface between behavioral ecology, spatial ecology, and wildlife biology. I have previously worked on the effects of spatial and temporal variation in food abundance and hunting disturbance on behavior and life histories of Scandinavian brown bears. My current project is funded by the EU Marie Skłodowska-Curie actions under the grant agreement No 793077 . I am jointly working with the movement ecology group here in Frankfurt and the Scandinavian Brown Bear Research Project on consistent individual variation in the behavior of brown bears. It particularly interests me, to which degree such “bear personalities” are formed by maternal learning, individual learning, genetic relatedness, and variation in the environment.
Since May 2020 I am working together with researchers from the Ben-Gurion University in Israel on a project evaluating survival and performance of Egyptian vultures raised in captivity and release into the wild (German- Israeli Foundation for Scientific Research and Development: I-1465-413.13/2018 ). This project is of high conservation priority.
