Predicting valuable forest habitats using an indicator species for biodiversity

2020

Intensive management of boreal forests impairs forest biodiversity and species of old-growth forest. Effective measures to support biodiversity require detection of locations valuable for conservation. We applied species distribution models (SDMs) to a species of mature forest, the northern goshawk (Accipiter gentilis, goshawk), that is often associated with hotspots of forest biodiversity. We located optimal sites for the goshawk on a landscape scale, assessed their state under intensified logging operations and identified characteristics of goshawks' nesting sites in boreal forests. Optimal sites for the goshawk covered only 3.4% of the boreal landscape and were mostly located outside pro…

Comparison of methods to model species habitat networks for decision-making in nature conservation : the case of the wildcat in southern Belgium

2020

Facing the loss of biodiversity caused by landscape fragmentation, implementation of ecological networks to connect habitats is an important biodiversity conservation issue. It is necessary to develop easily reproducible methods to identify and prioritize actions to maintain or restore ecological corridors. To date, several competing methods are used with recurrent debate on which is best and if expert-based approaches can replace data-driven models. We compared three methods: knowledge-driven (expert based), data-driven (based on species distribution model), and a mixed approach. We quantified their differences in habitat and corridor mapping, and prioritizations of landscape elements in t…

Le char du tumulus du Trembloi, commune de Magny-Lambert (Côte-d’Or)

2013

L’étude des collections protohistoriques du Musée archéologique de Dijon nous a mené à enquêter sur un fragment de moyeu de char hallstattien conservé dans la collection Brulard et indiqué comme provenant du tumulus du Trembloi à Magny-Lambert (Côte-d’Or). Si, depuis les travaux de R. Joffroy, le doute concernant la provenance de cet objet semblait permis, la mise à notre disposition de l’inventaire du musée ainsi que des manuscrits inédits du docteur Brulard et les détails qu’ils révèlent permettent de contredire cette thèse. Study of the protohistoric collections in the Archaeological Museum of Dijon led to us to investigate a fragment of an iron hub from an early Iron Age wagon in the Br…

The Management of Diversity in Schoolscapes

2015

The material environment of formal education (i.e., schoolscape) is determined not only by laws and local regulations, but by the visual practices of the given institution as well. Inscriptions and cultural symbols placed on the façade and the walls of the school building are tools for orienting the choice between various cultural and linguistic values and ideologies (Johnson 1980; Brown 2012). Based on photographs and research interviews collected in Budapest, I analyse both the material environments of four schools and the metadiscourses through which such spaces are interpreted and regulated. Investigation took place in both mainstream state schools as well as in private schools with alt…

Preprinting is positively associated with early career researcher status in ecology and evolution.

2021

Abstract The usage of preprint servers in ecology and evolution is increasing, allowing research to be rapidly disseminated and available through open access at no cost. Early Career Researchers (ECRs) often have limited experience with the peer review process, which can be challenging when trying to build publication records and demonstrate research ability for funding opportunities, scholarships, grants, or faculty positions. ECRs face different challenges relative to researchers with permanent positions and established research programs. These challenges might also vary according to institution size and country, which are factors associated with the availability of funding for open acces…

Current agri-environmental policies dismiss varied perceptions and discourses on management of traditional rural biotopes

2017

Abstract Traditional rural biotopes (TRBs) are threatened habitats that host significant biodiversity and several ecosystem services, and depend on active management such as low-intensity grazing. The current study explores private landowners’ decision-making on TRB management and abandonment within a social-ecological system framework. We provide insight into supporting resilience of TRB systems in the face of agricultural modernization. Using a mixed methods approach with content analysis and Q analysis, we demonstrate that TRB management fosters cultural, biological, aesthetic, and utilitarian values. These are reflected in different ways through conservationist’s, profit-oriented farmer…

Do highly ornamented and less parasitized males have high quality sperm? - an experimental test for parasite-induced reproductive trade-offs in Europ…

2014

Parasites take their resources from hosts and thus directly reduce available resources for hosts’ own body functions, such as growth and reproduction. Furthermore, parasite infections cause significant indirect costs to their hosts in terms of increased investments on immune defense. In this study, we investigated the impact of parasite infection on the sperm quality and expression of secondary sexual ornamentation (saturation of the red abdominal colouration and number of breeding tubercles) in the Eurasian minnow (Phoxinus phoxinus). We exposed minnows to a high and low dose of common nonspecific fish ectoparasite, the glochidia larvae of duck mussel (Anodonta anatina) and tested whether …

Data from: Large birds travel farther in homogeneous environments

2019

Aim: Animal movement is an important determinant of individual survival, population dynamics, and ecosystem structure and function. Yet it is still unclear how local movements are related to resource availability and the spatial arrangement of resources. Using resident bird species and migratory bird species outside of the migratory period, we examined how the distribution of resources affect the movement patterns of both large terrestrial birds (e.g., raptors, bustards, hornbills) and waterbirds (e.g., cranes, storks, ducks, geese, flamingos). Location: Global Time Period: 2003 - 2015 Major taxa studied: Birds Methods: We compiled GPS tracking data for 386 individuals across 36 bird specie…

Data from: Oxygen and carbon isoscapes for the Baltic Sea: testing their applicability in fish migration studies

2018

Conventional tags applied to individuals have been used to investigate animal movement, but these methods require tagged individuals be recaptured. Maps of regional isotopic variability known as “isoscapes” offer potential for various applications in migration research without tagging wherein isotope values of tissues are compared to environmental isotope values. In this study, we present the spatial variability in oxygen (math formula) and dissolved inorganic carbon (δ13CDIC) isotope values of Baltic Sea water. We also provide an example of how these isoscapes can reveal locations of individual animal via spatial probability surface maps, using the high-resolution salmon otolith isotope da…
