Pichancourt J.B. auteur aut IRD Burel F. auteur aut IRD Auger Pierre auteur aut IRD text journalArticle eng text/pdf born digital access To better understand the role of habitat quality and boundaries on population dynamics at the landscape scale, we develop a model combining a spatially implicit approach, a spatial population Leslie-type model and an implicit model of habitat fragmentation. An original approach of elasticity permits to identify which types of element and boundary influence the most population viability according to the wood fragmentation degree. The studied species is a corridor forest insect sensitive to fragmentation (Abax parallelepipedus, Coleoptera, Carabidae). We show that a single large patch of wood is better than several small patches for the population viability. specialized Abax parallelepipedus wood fragmentation spatial Leslie type model time scales SLOSS asymptotic population growth rate elasticity analysis 020 329 1 31-39 2006 1631-0691 https://www.documentation.ird.fr/hor/fdi:010035849 10.1016/j.crvi.2005.09.009 1631-0691 [F B010035849] https://www.documentation.ird.fr/hor/fdi:010035849 https://www.documentation.ird.fr/intranet/publi/2006/02/010035849.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2006-03-30 2017-08-23 fdi:010035849 fre
