We present d<strong>at</strong>a on <strong>the</strong> ecological conditions <strong>of</strong> <strong>the</strong> wetland habit<strong>at</strong>s in <strong>the</strong> Albenga<br />
plain (province <strong>of</strong> Savona) inhabited by <strong>the</strong> last remaining individuals <strong>of</strong> <strong>the</strong><br />
European pond turtle Emys orbicularis in Liguria. Most <strong>of</strong> <strong>the</strong> turtle's primary<br />
habit<strong>at</strong>s in this region – coastal temporary ponds, river pools, slow-flowing streams<br />
- have been heavily altered or destroyed during <strong>the</strong> 1960s and 1970s, when<br />
traditional farming activities have been substituted by intensive agriculture. For this<br />
reason, <strong>the</strong> present occurrence <strong>of</strong> pond turtles seems to be mainly restricted to<br />
secondary habit<strong>at</strong>s showing enviromental conditions similar to n<strong>at</strong>ural primary<br />
habit<strong>at</strong>s: slow-flowing w<strong>at</strong>er bodies cre<strong>at</strong>ed by <strong>the</strong> construction <strong>of</strong> small dams on<br />
fast-moving streams, permanent or temporary pools within abandoned quarries on<br />
clay substr<strong>at</strong>e. The conserv<strong>at</strong>ion measures undertaken in order to protect <strong>the</strong>se<br />
biotopes and to ensure <strong>the</strong> survival <strong>of</strong> pond terrapins in Liguria are discussed.<br />

On <strong>the</strong> Iberian Peninsula <strong>the</strong> western limit <strong>of</strong> <strong>the</strong> geographical range <strong>of</strong> Emys<br />
orbicularis overlaps with <strong>the</strong> nor<strong>the</strong>rn limit <strong>of</strong> <strong>the</strong> range <strong>of</strong> Mauremys leprosa.<br />
Given <strong>the</strong>ir distinct distributions, which probably reflects distinct ecological<br />
adapt<strong>at</strong>ions, we expect some geographical segreg<strong>at</strong>ion to occur between <strong>the</strong> species<br />
on <strong>the</strong> Iberian Peninsula. Coexistence p<strong>at</strong>terns <strong>of</strong> both species in Portugal were<br />
analyzed <strong>at</strong> coarse and local scales. At a coarse scale occurrences were rel<strong>at</strong>ed to<br />
environmental variables (clim<strong>at</strong>e, geomorphology, landscape fe<strong>at</strong>ures and human<br />
popul<strong>at</strong>ion density) compiled in UTM 10 x 10 km grid squares, using a generalised<br />
additive modelling (GAM) procedure and a Geographic Inform<strong>at</strong>ion System (GIS).<br />
We used presence/absence d<strong>at</strong>a as response variables for <strong>the</strong> models, compiled from<br />
a recently upd<strong>at</strong>ed Atlas <strong>of</strong> <strong>the</strong> Portuguese Herpet<strong>of</strong>auna. Although some isol<strong>at</strong>ed<br />
popul<strong>at</strong>ions <strong>of</strong> Emys orbicularis occur in northwestern Portugal, most occurrences<br />
