Dr. Jaeger received his PhD from the Department of Environmental Sciences at the ETH Zurich (Swiss Federal Institute of Technology) in 2000. He held a position at the Centre of Technology Assessment in Baden-Württemberg in Stuttgart, Germany, and lectured at the University of Stuttgart. In 2001, he went to Canada As a postdoctoral fellow with Dr. Lenore Fahrig in her Landscape Ecology Laboratory at Carleton University, Ottawa, funded by the German Academy of Natural Scientists Leopoldina. From 2003 to 2007 he was back in Zurich at the ETH as a research associate and was funded by the German Research Foundation DFG, the Swiss National Science Foundation SNF, the Swiss Federal Roads Authority, and the Swiss Federal Office for the Environment. His two last larger projects in Zurich were on the degree of landscape fragmentation and the degree of urban sprawl in Switzerland as indicators for the Swiss Monitoring System of Sustainable Development (MONET). He joined Concordia University in July 2007. In October 2010, he received the Dean's 2009-2010 New Scholar Award for outstanding achievement by a tenure-track faculty member. His research team received the IENE Project Award 2011 for their project "Landscape Fragmentation in Europe" from the Infra Eco Network Europe in September 2011 (Link).

In addition to his position at the Department of Geography, Planning and Environment, he is an affiliated member of the Department of Biology.

Research areas: Dr. Jaeger is working in the fields of landscape ecology, road ecology, the quantification and assessment of landscape structure and landscape change, land consumption through urban sprawl, ecological modelling, environmental indicators, impact assessment, and novel concepts of problem-oriented transdisciplinary research.

Research

News

Save the date: October 23-25, 2017. This is the date of the conference "Road Ecology & Climate Change Adaptation: From Research to Action". Location: Quebec City (QC), Hotel Ambassadeur. It will be in French and English. More information (and a website) will follow soon. Available so far are a leaflet in English and one in French.  

Our meta-analysis about the effectiveness of road mitigation measures to reduce traffic mortality of wildlife is now published in PLoS ONE: Trina Rytwinski, Kylie Soanes, …, Edgar van der Grift (2016): "How effective is road mitigation at reducing road-kill? A meta-analysis". It is the result of our last three meetings of the "Road Castle Group" (and work outside of these meetings). You can find a lay summary in the Concordia News here: "New Research: How to Reduce Roadkill". We are now working on a meta-analysis about mitigation measures to reduce the barrier effect of roads.   

Aurora's paper from her PhD thesis about large-scale wildlife responses to man-made infrastructure has been published in PNAS Early Edition on July 11, 2016 - you can find it here: http://www.pnas.org/content/early/2016/07/05/1522488113.full  Sarah DeWeerdt summarized it very nicely for a general audience in Conservation Magazine here.  
  
The global conference of the International Association for Impact Assessment (IAIA) 2017 was in Montreal on April 4-7, 2017. Our session, chaired by Aurora Torres and Jochen Jaeger: "Road Ecology in IA: New methods and platforms to move towards larger scales" went very well. Our session included papers from scholars and practitioners that (1) evaluate the effects of roads or other infrastructure on wildlife from all parts of the world, (2) propose novel methods for quantifying the magnitude and/or spatial distribution of these effects, and (3) are interested in approaches to improve knowledge exchange in international communities through open online platforms. Our session about "Uncertainty analysis and communication in IA practice and decision making" was chaired by Jill Blakley. It was very well attended.     

Our new report about "Urban Sprawl in Europe" has been published in June 2016 on the Highlights website of the European Environment Agency - have a look at it here: 
http://www.eea.europa.eu/highlights/better-targeted-measures-needed-to. It is also covered by the News of Concordia University here, together with Naghmeh's work about urban sprawl in Montreal and Quebec City. The journal 'Metro' also wrote about her work on 25 July 2016 (it even was on their title page)
The Urban-Sprawl-Metrics toolset (USM toolset) and the User Manual are now available here: www.wsl.ch/info/fokus/zersiedelung/onlinetool/index_EN  

The new brochure about our project "Earth Observation in support of the City Biodiversity Index (EO4CBI)" is now available here: http://spectrum.library.concordia.ca/981925/

We are currently working on four major research projects (and a few smaller projects):
- Earth Observation in support of the City Biodiversity Index (EO4CBI) (brochure),
- Speak no evil, hear no evil? Uncertainty analysis and communication in Canadian environmental impact assessment practice and decision making (more information here and here),
- Monitoring the use and effectiveness of wildlife passages along HW 175 for small and medium-sized mammals (see News Bulletins below),
- Urban sprawl in Europe (more information here and here).
   Here is an interview with Jochen Jaeger about research on urban sprawl done in his lab (in French).  

Openings and opportunities for students

I am currently looking for MSc and PhD students to work with me starting summer or fall 2018.
There are many opportunities in my lab including field work, GIS (e.g., landscape metrics), or computer simulation modeling (or combinations of them). You are welcome to bring your own research ideas. Generally, my reserach interests include landscape ecology, road ecology, the quantification and assessment of landscape structure and landscape change, urban sprawl, ecological modelling, environmental indicators, environmental impact assessment, as well as inter- or trans-disciplinary combinations of them - e.g., ones that include quantitative, qualitative, or mixed-methods approaches. I have applied for funding at various places (under review).

 

Various Honours thesis topics are available; for example: "How to set limits to control environmental degradation?"

I am currently looking for an Honours student to work on a project about procedures to introduce limits to control environmental degradation. More information HERE. Various other topics are also available. 

Voluntary work

Building a Database of Environmental Assessment Reports about Roads

This project compares the strengths and weaknesses of environmental assessment (EA) reports to identify best practices and to learn from them for preparing future environmental assessments. To achieve this goal, a database has been created that now needs to be populated with EA reports and analyzed. You are highly welcome to help with this work. You will learn a lot about environmental impact assessment, how EA reports are prepared in practice, what methods are used, and what their strengths and weaknesses are. You can start this work at any time.

I am looking forward to hearing from you. If you already have some knowledge in computer modelling/programming, GIS, statistical analysis, or other quantitative skills, I would particularly like to encourage you to get in contact with me.

6. Road effects model for predicting when animal populations are at risk from roads: an interactive model of road avoidance behaviour
- Click here to start the model -
Roads and traffic affect animal populations detrimentally in four ways: they decrease habitat amount and quality, enhance mortality due to collisions with vehicles, prevent access to resources on the other side of the road, and subdivide animal populations into smaller and more vulnerable fractions. Roads will affect persistence of animal populations differently depending on (1) road avoidance behavior of the animals (i.e., noise avoidance, road surface avoidance, and car avoidance); (2) population sensitivity to the four road effects; (3) road size; and (4) traffic volume. We have created a model based on these population and road characteristics to study the questions: (1) what types of road avoidance behaviors make populations more vulnerable to roads?; (2) what types of roads have the greatest impact on population persistence?; and (3) how much does the impact of roads vary with the relative population sensitivity to the four road effects?
Our results suggest that, in general, the most vulnerable populations are those with high noise and high road surface avoidance, and secondly, those with high noise avoidance only. Conversely, the least vulnerable populations are those with high car avoidance only, and secondly, high road surface and high car avoidance. Populations with low overall road avoidance and those with high overall road avoidance tend to respond in opposite ways when the sensitivity to the four road effects is varied. The same is true of populations with high road surface avoidance when compared to those with high car and high noise avoidance. The model further predicted that traffic volume has a larger effect than road size on the impact of roads on population persistence. One potential application of our model is to generate predictions for more structured field studies of road avoidance behavior and its influence on persistence of wildlife populations.

8. What are the objectives of environmental science?
Dr. Martin Scheringer and I want to start a critical discussion of this question. Therefore, we investigate the kinds of research questions asked by environmental scientists. To do this, we are taking a closer look at four questions:

  • What is the lack of knowledge to be addressed by the research?
  • What is the purpose of the results?
  • What are the subjects the research is dealing with?
  • What are the methods chosen for the investigation?
We propose that problem-oriented environmental science should strive to find answers to these questions that are different from those offered by ‘classical’ natural sciences.
The reason is that in the treatment of environmental problems, there is often a discrepancy between the needs of dicision makers and the results provided by scientific research (what we call the “datadilemma”). To explore how this discrepancy could be reduced, we make a distinction between knowledge-oriented and decision-oriented reduction of complexity. The challenge that today's environmental research is facing is that decision-oriented reduction of complexity should be incorporated in the selection of scientific problems. We use the guiding principle of “reflexive environmental research” and point out how it differs from the guiding principles of “classical scientific research”. Its key elements are: reflection of guiding ideas external to science (e.g., sustainability); addressing explicitly the uncertainty and openness of scientific results and forecasts (including unknown unknowns); transdisciplinarity; the aim of contributing to the solution of complex and controversial real-world problems; adherence to relevant scientific standards.
