We also determined the relative contribution of local, landscape, and spatial factors explaining the diﬀerences in the distribution patterns of the two species in the region. Using a kriging interpolation method, we obtained a map of sympatric and allopatric areas of species occurrence. The estimated sympatry area corresponded to a northwest–southeast belt representing 11.3% of the study area. Habitat niche diﬀerences were assessed with binomial GLMs followed by a variance partitioning. At a local scale, higher altitude, higher cover of shrubs, lower clay content in the soil, and lower cover of tree canopy were the most important factors distinguishing M. lusitanicus presence sites from those with M. duodecimcostatus. At a larger scale, the presence of forest landscape units and the low abundance of ‘‘montado’’ units were the most inﬂuencing landscape factors in the identiﬁcation of M. lusitanicus occurrence sites when compared to M. duodecimcostatus. Our results suggested that local coexistence of M. lusitanicus and M. duodecimcostatus in the ﬁeld is a rare event. The diﬀerences in distribution patterns of the two pine vole species were mostly explained by ﬁne-scale environmental factors and by shared spatial eﬀects.</style></abstract><issue><style face="normal" font="default" size="100%">5</style></issue></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%">Cocco, Arturo</style></author><author><style face="normal" font="default" size="100%">Cossu, Antonio Q.</style></author><author><style face="normal" font="default" size="100%">Erre, Patrizia</style></author><author><style face="normal" font="default" size="100%">Nieddu, Giovanni</style></author><author><style face="normal" font="default" size="100%">Luciano, Pietro</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Spatial analysis of gypsy moth populations in Sardinia using geostatistical and climate models</style></title><secondary-title><style face="normal" font="default" size="100%">Agricultural and Forest Entomology</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">floramap</style></keyword><keyword><style  face="normal" font="default" size="100%">geographic information system</style></keyword><keyword><style  face="normal" font="default" size="100%">kriging</style></keyword><keyword><style  face="normal" font="default" size="100%">Lymantria dispar</style></keyword><keyword><style  face="normal" font="default" size="100%">probability map</style></keyword><keyword><style  face="normal" font="default" size="100%">spatial distribution</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2010///</style></date></pub-dates></dates><urls><web-urls><url><style face="normal" font="default" size="100%">http://doi.wiley.com/10.1111/j.1461-9563.2010.00488.x</style></url></web-urls></urls><volume><style face="normal" font="default" size="100%">12</style></volume><pages><style face="normal" font="default" size="100%">417 - 426</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">1 Spatial ﬂuctuations of the Sardinian population of the gypsy moth Lymantria dispar (L.) (Lepidoptera: Lymantriidae) were characterized using geostatistical and climate models. Data on gypsy moth egg mass abundance recorded at 282 permanent monitoring sites from 1980 to 2004 were incorporated in a geographic information system with the vegetational, geomorphological and pedological features of the sites. 2 Statistical analyses revealed that the relative outbreak frequency was related to the predominant host tree, slope and elevation of the monitoring sites, whereas there was no correlation between outbreak frequency and exposure and soil type. 3 By using bioclimatic modelling, probability maps of gypsy moth outbreaks were generated. The model identiﬁed a probability surface with climatic conditions favourable to gypsy moth outbreaks and thus potentially subject to defoliation. The maps included 92 sites where outbreaks never occurred, suggesting that the Sardinian climate may not be a determinant factor for gypsy moth outbreaks. 4 The geostatistical method cokriging with outbreak frequency as a covariate was found to be the most suitable technique to estimate gypsy moth egg mass abundance. Semivariograms showed spatial correlation of egg mass abundance within the range 18.5–53 km. The results obtained were used to create regional gypsy moth distribution maps by cokriging, which demonstrated the outbreak foci and different infestation levels at each monitoring area.
