From birds to butterflies: animal movement patterns and stable isotopes.
Establishing patterns of movement of wild animals is crucial for our understanding of their ecology, life history and behavior, and is a prerequisite for their effective conservation. Advances in the use of stable isotope markers make it possible to track a diversity of animal species in a variety of habitats. This approach is revolutionizing the way in which we make connections between phases ...
متن کاملSomme Coloration De Graphe
RÉSUMÉ : Dans cet article nous étudions le problème de la somme coloration minimale (MSCP) qui consiste à trouver une coloration des sommets d’un graphe, utilisant des entiers naturels, telle que la somme des couleurs est minimale. Nous présentons une synthèse des travaux sur MSCP, ainsi qu’une nouvelle famille d’algorithmes gloutons pour MSCP. Nous proposons une étude de bornes inférieures bas...
متن کاملSomme Ponctuelle D’opérateurs Maximaux Monotones
The primary goal of this paper is to shed some light on the maximality of the pointwise sum of two maximal monotone operators. The interesting purpose is to extend some recent results of Attouch, Moudafi and Riahi on the graphconvergence of maximal monotone operators to the more general setting of reflexive Banach spaces. In addition, we present some conditions which imply the uniform Brézis-Cr...
متن کاملBirds and Butterflies in Swedish Urban and Peri-urban Habitats: a Landscape Perspective
Hedblom, M. 2007. Birds and butterflies in Swedish urban and peri-urban habitats: a landscape perspective. Doctor's dissertation. Urbanisation is considered to be one of the largest threats to biodiversity although little is known about the effect of habitat fragmentation on native flora and fauna in urban areas in general, and in Sweden specifically. In this thesis, data have been collected us...
متن کاملCitizen Science and the Urban Ecology of Birds and Butterflies — A Systematic Review
Citizen science has gained widespread currency as a tool for ecological research over the past decade. However, in the discipline of urban ecology, the existing contributions and future potential of citizen science engagement, specifically in terms of knowledge gain, have not yet been comprehensively explored. Here, we present a systematic review of published work on the urban ecology of birds ...
