“…It was dated at approximately 1.4-0.7 Mya and explained by Peistocene climatic oscillations (Fritz et al 2009). Finally, this area also corresponds to the zone of transition between the two shrew species Crocidura pachyura (East Algeria, Tunisia, Sardinia) and Crocidura russula (western Algeria, Morocco, mainland Europe), which diverged about 2.2 Mya (Cosson et al 2005;Nicolas et al 2014a).…”

We studied the phylogeography of the Sahara frog in North Africa. We widely sampled frogs from Morocco to Tunisia (195 individuals) and sequenced two mitochondrial (16S and CO1) and one nuclear (Rag1) genes. Our results confirm that Moroccan populations of Pelophylax saharicus are genetically distinct from Algerian ones. Specimens from Alger and Djelfa (central Algeria) are genetically closer to Moroccan specimens than to east Algerian ones, and the split between these two lineages may have occurred approximately 2.6 Mya. A similar pattern of differentiation was observed in several other species and was hypothesized to be linked to the formation of the fossil island called the 'Edough Peninsula' in eastern Algeria around 4.2 Ma and then to have been reinforced by Pleistocene climatic changes. At the Moroccan scale, we found a low level of genetic diversity and no clear phylogeographic pattern within P. saharicus. However, our SAShA analyses revealed a mixture of random and underdistributed haplotypes, which may indicate a complex population genetic or biogeographic history.

“…Recent molecular analyses confirmed the presence of C. pachyura in Algeria from sea level up to 1390 m (Nicolas et al, 2014). The sister species of C. pachyura, Crocidura russula, is widely distributed in western Algeria, Morocco and western Europe (Ramalhinho et al, 1999), while C. pachyura is considered to occur in Algeria (Kabylie region), Tunisia and the Mediterranean islands Pantelleria, Sardinia and Ibiza (Brändli et al, 2005;Turni et al, 2007;Nicolas et al, 2014). According to Contoli & Aloise (2001), C. pachyura could be present from Tunisia up to the Cherchell site (wilaya of Tipaza, 80 km west of Alger) in Algeria.…”

Régime alimentaire de Crocidura pachyura (Küster, 1835) (Mammalia, Soricidae) dans plusieurs localités d'Algérie.-Le régime alimentaire de Crocidura pachyura (Küster, 1835) a été étudié grâce à l'analyse des contenus stomacaux de 95 spécimens collectés sur le terrain de juin 2007 à septembre 2008 et de mars 2012 à mai 2014. Ces individus ont été collectés au moyen de pièges Sherman et de pots-enterrés dans 8 localités d'Algérie du Nord et du Centre, du niveau de la mer à 1390 m d'altitude (Tigzirt, Boukhalfa, Ouadias, El Misser, Darna, Tala Guilef, Zeralda et Reghaia). On trouve 99 proies différentes distribuées dans 7 taxons d'invertébrés (Clitellates, Nématelminthes, Gastropodes, Arachnides, Crustacés, Myriapodes et Insectes), un vertébré (Squamate) et des plantes indéterminées, notamment des graines. Les invertébrés représentent 77,05 % du régime alimentaire et les insectes sont les proies les plus fréquentes avec 54,3 %. Crocidura pachyura se nourrit de petites proies de taille inférieure à 17 mm (moyenne 4 mm) et la diversité des proies (indice de diversité de Shannon-Weaver) varie de 1,58 à 4,88 (moyenne de 2,4). La comparaison avec les travaux similaires effectués en Algérie et en Europe sur C. russula montre quelques différences de régime, surtout en ce qui concerne les proportions des proies Coleoptères, Hyménoptères et Diptères.SUMMARY.-Ecological information, including food habits, on African shrews is scarce. The aim of this study was to describe the diet of Crocidura pachyura (Küster, 1835) in Algeria. Its diet was studied by analysing stomach contents of 95 shrews collected in pitfall and Sherman traps,

“…Several others were directly captured, and the body measurements appeared to be within the variability of just one of the two species in sympatric areas [20]. We kept, for analyses, occurrences from areas including sympatric populations of both C. russula and C. suaveolens only if the identification was deemed reliable [31], as well as occurrences from areas where previous genetic work confirmed the presence of only one of these species [18,19,24,26,38]. Occurrences that could not be unambiguously assigned to one species were excluded.…”

The genus Crocidura (Eulipotyphla, Soricidae) is the most speciose genus amongst mammals, i.e., it includes the highest number of species. Different species are distinguished by skull morphology, which often prevents the identification of individuals in the field and limits research on these species’ ecology and biology. We combined species distribution models and molecular analyses to assess the distribution of cryptic Crocidura shrews in Italy, confirming the occurrence of the greater white-toothed shrew Crocidura russula in the northwest of the country. The molecular identification ascertained the species’ presence in two distinct Italian regions. Accordingly, species distribution modelling highlighted the occurrence of areas suitable for C. russula in the westernmost part of northern Italy. Our results confirm the role of Italy as a mammal hotspot in the Mediterranean; additionally, they also show the need to include C. russula in Italian faunal checklists. To conclude, we highlight the usefulness of combining different approaches to explore the presence of cryptic species outside their known ranges. Since the similar, smaller C. suaveolens may be displaced by the larger C. russula through competitive exclusion, the latter might be the species actually present where C. suaveolens had been reported previously. A comprehensive and detailed survey is therefore required to assess the current distribution of these species.
