The aim of this project is to develop systems for the acquisition of data and monitoring of wildlife based on unmanned aircraft systems (UASs). We will focus on two areas of application:

-Wildlife census and monitoring. UASs offer a great opportunity to substantially improve the process of wildlife monitoring and surveillance by being a cost-effective method, with lower disturbance and higher accuracy than traditional approaches, particularly in remote or difficult-to-access areas. The major drawback of this approach is related to the analysis of the data since manual processing of a large number of images to detect individuals is a time consuming task. Thus, our aim will be to implemente an automatic recognition system of wildlife based on data acquired by UASs.

-Wildlife tracking and location. The deployment of electronic devices on wildlife is widely extended and has multiple applications; it allows to record the movements of the marked individuals, serves to locate their feeding and breeding areas or permits registering multiple activity and physiological parameters. VHF radio tagging and gps logging devices are nowadays two of the most common wildlife marking systems, but tracking and (re) capturing animals maybe challenging and is both time-consuming and expensive. The use of UASs to automatically track and locate animals is a promising solution by having a great potential to reduce cost and efforts in this research field.

The Crowned Solitary Eagle (Buteogallus coronatus) is one of the rarest and most severely threatened birds of prey in the Neotropical region. Its range extends from southern Brazil to northern Patagonia, where it inhabits a variety of forested habitats, including woodlands and other savanna-like landscapes. The species is listed as endangered under the IUCN Red List with a declining world population estimated at less than one thousand reproductive individuals. Reduced population size and range contraction of Crowned Solitary Eagles is suspected to be human induced, including habitat, electrocution, as well as shooting.

Possibly, because Crowned Solitary Eagles occurs in low densities in remote and barely explored areas, little is known about the biology of the species and no information exists on the demography and population connectivity between geographic regions. Likewise, there is a lack of knowledge on the extent to which population decline and range contraction have affected levels of genetic diversity in this species. The main goal of this project is evaluate the genetic status of Crowned Solitary Eagles. Specifically, the project focuses on::

1. Estimate the neutral genetic diversity (microsatellites) and investigate the existence of population structure between populations of this endangered species.

2. Evaluate, using historical and contemporary samples, the genetic impact of the demographic reduction experienced by the Crowned Solitary Eagle.

3. Develop monitoring protocols of the species using non-invasive techniques.

Climate change is one of the major driving forces for adaptive shifts in migration and breeding phenology, and possibly impacts demographic changes if a species fails to adapt sufficiently. In Western Europe, pied flycatchers (Ficedula hypoleuca) have insufficiently adapted their breeding phenology to the ongoing advance of food peaks within their breeding area, and consequently suffered local population declines. Here, we will test for potential effects of global change on the genetic architecture of populations using two neutral marker sets (mitochondrial control region and microsatellites) and one potentially selectively non-neutral marker (avian clock gene). We will use current and historic samples from six European pied flycatcher populations (Finland, Germany, Norway, Spain, Sweden and the Netherlands), covering a large part of the species’ breeding range.
