The present study was conducted to assess the genetic diversity and population genetic structure of three sheep populations namely; Sawakni (SW), Berberi (BR) and Najdi (NJ), in Saudi Arabia, utilizing 45, 18 and 31 individual blood DNA extractions...
Two gadiform species with a successive bathymetric and an ecological and economical importance in the Mediterranean fishing industry, Phycis blennoides and Phycis phycis, were selected for the present study. A total of 592 fresh specimens belonging...
We present the results of a chromosomal study (C-, Ag-NOR-, endonuclease digestion, DAPI and CMA3 banding) carried out on four Tunisian species of amphibians: Bufo mauritanicus, B. viridis,Rana saharica and Discoglossus pictus auritus. For...
Larval forms of the genus Anisakis were reported infecting several fish species from the North African coasts of central Mediterranean Sea. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was used to...
Fasciolosis caused by Fasciola spp. (Platyhelminthes: Trematoda: Digenea) is considered the most important helminth infection of ruminants in tropical countries, causing considerable socioeconomic problems. In the present study, samples identified...
Rana saharica is the most widely distributed anuran in Tunisia. We examined morphological variation in 124 specimens as a function of their geographical origin, using univariate and multivariate statistics with traditional morphometrics. Our results...
The water frog Pelophylax saharicus is the most widespread anuran in North Africa and thus subjected to widely differing environmental conditions in different parts of its distribution range. In this paper we examined genetic structure of species 15...
Morphometric variation of Pelophylax saharicus was analysed using univariate and multivariate statistics, with both traditional and geometric morphometrics, based on 148 specimens from four different geographical localities in Tunisia and Algeria....
To assess karyological and morphometric diversity within Discoglossus pictus Otth 1837, morphometric and cytogenetic analyses were carried out on five populations from the northern Tunisia and Algeria. A total of eight morphometric adult traits were...
The intraspecific variation of mitochondrial cytochrome b sequence was analysed for two widely distributed Tunisian anuran species, Discoglossus pictus and Pelophylax saharicus. We observed low genetic variation within both species (D. p. auritus 0....
A new highly abundant satellite DNA from Discoglossus pictus (Dp-sat1) was isolated and characterized. The repetitive unit (0.51 kb) has 2 HindIII sites and only one SpeI site: digestion of genomic DNA with HindIII produces 3 fragments: HA (0.17 kb...
 Fasciolosis caused by Fasciola spp. (Platyhelminthes: Trematoda: Digenea) is considered the most important helminth infection of ruminants in tropical countries, causing considerable socioeconomic problems. Samples identifi ed morphologically as...

Larval forms of the genus Hysterothylacium have been previously reported in teleost fish from the North African coasts of central Mediterranean Sea by morphological analysis. In the present study, samples identified morphologically as ...

This study describes patterns of geographic variation in morphometric characters of the African green toad Bufo boulengeri, from Tunisia (11 populations). Body size differences of 89 specimens were analysed with univariate statistics, and body...
Two new high repetitive DNAs were isolated from Discoglossus pictus genomic DNA digested with StuI. Sequence analysis of clones indicated two types of repetitive units 143–148 bp and 170–177 bp long, respectively. Southern blot analyses show ladders...
Genetic variation among 39 samples from 16 populations of the North African green frog Pelophylax saharicus from Tunisia was investigated, using 513 bp partial sequences of the mitochondrial gene cytochrome b. P. saharicus exhibits little genetic...
  Since the introduction of quinacrine mustard as a banding agent, it was a revolution on cytogenetics. Fluorochrome banding technique using quinacrine produces a yellow fluorescence of differing intensity (Q-bands). Q-banding was first developed...
Morphometric and karyological variations were analysed within the Moorish gecko Tarentola mauritanica sensu lato from Tunisia, and compared with already published data. The results show high levels of interspecific variability, indicative of the...
The aim of the present study is to investigate for the first time the genetic diversity of samples identified morphologically as Fasciola hepatica (Platyhelminthes: Trematoda: Digenea) (n = 66) from sheep and cattle from two localities of Sardinia...
Trochoidea (Trochoidea) caroni (Deshayes, 1832), with T. (T.) elegans (Gmelin, 1791) and T. (T.) trochlea (Pfeiffer, 1846), belong to a group of species (“elegans group”), which, although considered valid by most authors, show a not completely...
The North African amphibian fauna was once regarded as limited in diversity, but increased field and laboratory  research in the region has subsequently revealed considerable endemism and data such as these are necessary for making objective and...
In contrast to oceanic, continental islands are expected to show less diversification and endemism and thus phylogeographic signatures of multiple colonization events from adjacent continents due to episodic connections by sea level changes. In...
