Link (Droseraceae) and their habitats throughout the species’ distribution range (Portugal, Spain and Morocco), and examine their relations. We have surveyed 32 populations and we analyse their demographic structures, accompanying plant communities (by TWINSPAN analyses), and relationships between population features and several edaphic and nonedaphic environmental variables (by multiple regression analyses). Plant communities, their ﬂoristic richness and degree of endemism change across the geographical range of Drosophyllum. Populations vary strongly in size, density and age structure. Their recruitment seems largely determined by competition with the surrounding vegetation, while only weak relationships were detected between population performance and other environmental factors. The demographic structure of populations exhibits a marked geographical differentiation, with populations becoming older and sparser towards the north-western part of the range. The largest and presumably most stable populations are mostly found in southern Spanish heathlands, which are nowadays scarcely affected by man. Moroccan populations suffer from browsing by cattle and experience an accelerated generation turnover, while most Portuguese populations occur in afforested areas and experience strongly reduced recruitment. The historical distribution range of Drosophyllum within its peculiar habitat has probably been relatively stable, but recent regional differences in human land use have resulted in present-day differences in population performance, as well as in types and degrees of threat across the three countries involved. Conservation strategies should take into account this range-wide variation and combine approaches on different spatial scales.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Garrido, B.</style></author><author><style face="normal" font="default" size="100%">Hampe, A.</style></author><author><style face="normal" font="default" size="100%">MARAÑON, T.</style></author><author><style face="normal" font="default" size="100%">Arroyo, J.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Regional differences in land use affect population performance of the threatened insectivorous plant Drosophyllum lusitanicum (Droseraceae)</style></title><secondary-title><style face="normal" font="default" size="100%">Diversity and Distributions</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">carnivorous plant</style></keyword><keyword><style  face="normal" font="default" size="100%">conservation</style></keyword><keyword><style  face="normal" font="default" size="100%">demographic structure</style></keyword><keyword><style  face="normal" font="default" size="100%">ecogeography</style></keyword><keyword><style  face="normal" font="default" size="100%">geographical range</style></keyword><keyword><style  face="normal" font="default" size="100%">mediterranean heathland</style></keyword><keyword><style  face="normal" font="default" size="100%">range-wide survey</style></keyword><keyword><style  face="normal" font="default" size="100%">Regeneration</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2003</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2003///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://doi.wiley.com/10.1046/j.1472-4642.2003.00029.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">9</style></volume><pages><style face="normal" font="default" size="100%">335 - 350</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">We analyse populations of the insectivorous plant Drosophyllum lusitanicum (L.)

Biometrical analysis of acorns and their cupules showed much greater variation among Spanish populations, encompassing the variation in Italy. The Spanish population at El Pardo, considered the type locality for Quercus rotundifolia, separated from all others. Multivariate analyses of the chemical data indicated, on the one hand, separation of Spain from Italy, and on the other hand, a separation of interior Spanish populations from coastal populations. The importance of lipid composition in the former separation may reflect genetic differentiation between these two origins. Coastal populations were closer to Italian and we suggest were a zone of introgression and hybridization between Quercus ilex and Q. rotundifolia and probably also Quercus coccifera at Bonete Albacete</style></abstract><issue><style face="normal" font="default" size="100%">7</style></issue><notes><style face="normal" font="default" size="100%">doi: 10.1139/b92-184doi: 10.1139/b92-184The following values have no corresponding Zotero field:&lt;br/&gt;publisher: NRC Research Press</style></notes></record></records></xml>
