A total of 35 morphological characters (biometry, scalation, chromatic pattern) were studied through multivariate analyses on 10 populations sampled across the range of the Iberian wall lizard (Podarcis hispanica) in Portugal. Biometry clearly splits the samples into two different types. Differences in scalation between the two types were not clear, but multiple correspondenc e analyses showed that different chromatic patterns t each of the types: one presented dark dorsal patterns (e.g. reticulated, eyeled, striped) and whitish-pearly belly, while the other showed green or yellow-brown patterns and yellow-orang e belly. These two morphotypes constitute different molecular lineages and have different ranges of distribution.

“…Therefore, the Strait of Gibraltar should act much less as a biogeographical barrier than the Strait of Sicily. Consequently, the biogeographical connectivity over the Strait of Gibraltar is supported by genetic analyses (Cosson et al, 2005), but more studies emphasize the biogeographical split between the Maghreb and Iberia (Beerli, Hotz & Uzzell, 1996;De Jong, 1998;Castella et al, 2000;Palmer & Cambefort, 2000;Harris & Sá-Sousa, 2002;Gantenbein & Largiadèr, 2003); this is also underlined in many Mediterranean species only occurring on one side of this sea strait, as, for example, in lepidopterans (only Iberia: Leptidea sinapis, Satyrium spini, Polyommatus bellargus, Melitaea parthenoides, Hipparchia semele, Aulocera circe; only Maghreb: Tomares mauretanicus, Taurucus rosaceus, Polyommatus punctifera, Hipparchia hansii, Coenonympha arcanioides, Thymelicus hamza; Tolman & Lewington, 1997, García-Barros et al, 2004Tarrier & Delacre, 2008).…”

The glacial-interglacial cycles have caused severe range modifications of species' distributions. In Europe, thermophilic species had to retreat into geographically distinct southern refugia during glaciations. This process produced strong genetic imprints, which are still detectable by the present pattern of genetic differentiation and the distribution of regional diversity. To reveal the biogeographical imprints in the western Mediterranean, we analysed 26 populations of the butterfly Maniola jurtina spread over large areas of its European and North African distribution range. The samples were analysed using allozyme electrophoresis. We detected three genetic groups, divided into Western Europe, Central/Eastern Europe, and Italy with the Maghreb. The North African samples randomly cluster within the Italian samples. Even the population sampled in Morocco is genetically closely related to these samples and not to the geographically neighbouring Iberian ones. Parameters of genetic diversity showed similar values over the whole study area. The observed genetic pattern reflects possible glacial refugia in Europe located in the Iberian Peninsula and the Balkans. For North Africa and Italy, our data reveal a colonization of Africa originating from Italy.

“…We focused on two species of wall lizards, Podarcis bocagei Seoane, 1884 and P. hispanica (Steindachner 1870) type 1A (sensu Harris and Sá-Sousa 2002). These two species present a particularly interesting system for studying morphology-function-ecology relationships, due to their largely shared evolutionary history and geographical distribution as well as their ecological differentiation.…”

Relationships between head morphology, bite performance and ecology in two species of Podarcis wall lizards

et al. 2011

Understanding the relationship between form and function is central to our comprehension of how phenotypic diversity evolves. Traits involved in multiple activities, such as social interactions and ecological resource use, are under the influence of different evolutionary forces potentially acting in opposite directions. Such systems provide the opportunity of understanding how potential constraints on morphological variation may influence whole-organism performance. In this study we examined morphology and bite performance in two closely related species of Podarcis wall lizards with divergent microhabitat preferences, to investigate how natural and sexual selection interact to shape the evolution of head traits. Our results show that although head morphology is markedly different between species and sexes, only sexes differ in bite force, indicating that the ecological differentiation between species is reflected in their morphology but does not constrain performance. Rather, the modification of the relative size of head components between species and a shift in the form-function relationship provide a potential explanation of how equal performance is attained by different morphological configurations. Geometric morphometrics provide a clear, biomechanically meaningful image of how this is achieved and show a bisexual pattern of head shape-bite force association in both species. This, together with a strong allometry of head size on body size and head shape on head size, provides indirect morphological evidence for the importance of sexual selection in shaping morphological and functional patterns. Finally, our findings suggest that the differences observed between species and sexes in head traits and bite performance are not reflected in their dietary ecology, implying that if trophic niche segregation between groups occurs, the reasons behind it are not primarily related to head morphology and functional variation.
