Utilisation de poudres fluorescentes pour l’analyse des déplacements des petits rongeurs dans la nature

Abstract

Les petits rongeurs marques ä l'aide de poudres fluorescentes peuvent etre suivis par les traces qu'ils laissent au sol; leurs deplacements sont ainsi materialises, leurs nids et leurs terriers localises.Les grands deplacements observes grace ä cette technique, chez toutes les especes etudiees, on t amene les auteurs ä modifier leurs protocoles d'echantillonnage des Murides.Cette technique s'est revelee efficace chez de nombreuses especes vivant dans diffe'-rents types de milieux (Mus musculus domesticus dans les dunes sableuses, Mus spre· tus et Apodemus sylvaticus dans la garrigue mediterrane'enne, Proechimys cuvieri en foret tropicale guyanaise, Hylomyscus stella et Hylomyscus fumosus en foret tropicale gabonaise).L'utilisation de ces pigments a egalement permis l'etude de la dispersion des glands par Apodemus sylvaticus dans la chenaic mediterraneenne.

Microhabitat use by Eligmodontia typus (Rodentia: Muridae) in the Monte Desert (Argentina)

“…Other techniques like radio tracking and luminous powder have been used to follow the tracks of animals and estimate microhabitat use. The last method, developed by Duplantier et al (1984), is very easy to use, cheaper than radio tracking, and shows low toxicity without deleterious effects on the individuals (Lemen and Freeman 1985;Stapp et al 1994). The purpose of this study was to evaluate microhabitat use by E. typus using luminous powder in sand dunes, where this species is dominant (Corbalan and Ojeda 2004).…”

Multi‐scale habitat selection of Mus minutoides in the Lowveld of Swaziland

“…To assess movements within the habitat, we dusted the first M. minutoides captured on each transect with fluorescent powder (A‐15‐N blaze orange pigment, DayGlo Color Corp.) and then each additional mouse that was trapped at least 30 m away to minimize overlapping pathways. To apply fluorescent powder, we placed each mouse into a bag containing powder and gently shook them (Duplantier et al ., ; Lemen & Freeman, ; Mullican, ). We released each individual at their capture location the following evening.…”

Efficiency of fluorescent powder tracking for studying use of space by small mammals in an African rainforest

“…Nearly 20 years ago, the new technique of powder tracking was developed for following movements of small mammals. It entails the use of fluorescent powders and ultraviolet light detectors (Duplantier et al. , 1984; Lemen & Freeman, 1985).…”
