Project 1 Boreal Raptor Project – Where do the eagles die and why?
Raptors are an important group of species, being the top predators, are at times conflict with humans. They are also indicators of ecosystem health. Studying the causes of mortality in raptors is critically important for ecological, conservation, and management questions. Raptors are especially sensitive to human activities such as habitat destruction, collisions with wind turbines, electrocution on power lines, pesticide use, and illegal hunting.
Eagle monitoring in Sweden is mainly focused on monitoring breeding parameters and currently does not include survival and mortality rates. These estimates are crucial for population management as projections cannot be made without such field data.
This project is aimed at identifying and quantifying the patterns and causes of mortality of Swedish Eagles (Golden and White-Tailed Eagles) using nationally compiled datasets and those followed in research. The eventual goal is to produce crucial demographic parameters that may inform national monitoring and conservation.
The work is a joint effort between Swedish University of Agricultural Sciences (SLU) and Naturhistoriska riksmuseet.
If you are someone looking for a diverse experience with strong interest towards Quantitative Ecology and Biodiversity, then this is for you. You get to work in a highly motivated and adventurous research group and have lots of fun with work. See www.goldeneagleswede.com; https://lnkd.in/dZjqtZTr

Linear infrastructure and associated wildlife accidents create an ecological trap for an apex predator and scavenger
Abstract
Animals may fall into an ‘ecological trap’ when they select seemingly attractive habitats at the expense of their fitness. This maladaptive behavior is often the result of rapid, human-induced changes in their natal environment, such as the construction of energy and transportation infrastructure. We tested the ecological trap hypothesis regarding human-created linear infrastructure on a widely distributed apex predator and scavenger—the Golden Eagle (Aquila chrysaetos), whose range spans the entire Northern Hemisphere. Roads and railways offer novel and attractive feeding opportunities through traffic-induced mortality of other species, while powerline areas provide perching or nesting sites and scavenging opportunities from electrocuted or collision-killed birds. These conditions may have negative demographic consequences for eagles if these apparent opportunities turn into traps. Using step selection functions, we analyzed habitat selection of 74 GPS-tracked Golden Eagles (37 adults and 37 immatures) during eleven years in Fennoscandia. To assess habitat attractiveness, we used wildlife traffic accident statistics for dominant wild species, and to evaluate demographic consequences, we used mortality data from the GPS-tagged eagles. Our analysis revealed that eagles selected linear features such as roads, railways and powerlines at both the population and individual levels. Both adult and immature eagles consistently selected these features, and the strength of selection for linear features increased with age in immature eagles. The linear features however had 5.5 times higher mortality risk for eagles than other selected habitats indicating the presence of an ecological trap. We discuss the implications of these findings for the conservation and population ecology of apex predators and scavengers, as well as their potential demographic consequences. To mitigate this issue, we urgently recommend the removal of carcasses from roads and tracks to prevent ecological traps for raptors and scavenger species worldwide. Additionally, we advocate for the development of methods and strategies to reduce wildlife traffic accidents.

The overall goal of the project is the effective conservation of the Golden eagle, through cross-border collaboration between Sweden, Finland, and Norway by: harmonization of population data collection methods and surveys, joint data analyses, and sharing of knowledge and best practice, including traditional knowledge, for future joint implementation and development of sustainable management strategies.
The specific objectives are to investigate the:
1. Population Ecology of northern golden eagle population (WP1)
2. Eagles and livestock (reindeer and sheep) interactions (WP2)
3. Eagles and land use (wind farms & forestry) relationships (WP3)
