A taxonomic revision of the Alchemilla in the High Atlas Mountains has been carried out. This genus is represented in Morocco by Alchemilla atlantica, A. gourzai, A. litardieri, A. mairei and by a new taxon A. boratynskii, sp. nov., described here from the High Atlas Mountains range. Data on their chorology, ecology and phenology, as well as an identification key, are provided. The conservation status of this newly described narrow endemic and the other four taxa, also endemics previously known from the Moroccan Atlas Mountains, is provided. Alchemilla hirtipes should be excluded from the flora of Morocco.

We assessed the genetic variation of 47 Moroccan populations of the North African water frog (Pelophylax saharicus) using partial sequences of the mitochondrial cytochrome oxidase subunit I gene (COI). All 239 samples belonged to the main haplotype clade previously identified from Morocco, with no haplotypes of the Algerian/Tunisian clades among our samples. Altogether 40 haplotypes were found, with a maximum of 13 mutational steps between them. Two weakly divergent haplogroups separated by a minimum of six mutational steps were distributed (i) in the Anti-Atlas and the Sahara (south of the High Atlas Mountains) versus (ii) in the Middle Atlas, the High Atlas, and in the Rif area north of the Atlas Massif. Haplotypes of the northern haplogroup were found at the southernmost locality, which might be due to human translocation, and co-occurrence of the two haplogroups was recorded at three sites within the range of the northern haplogroup.

Strong Relationships

Corynexochid trilobites of the Cambrian of Morocco are described and the subfamily Acontheinae is revised. With Kootenia beethoveni n. sp., Kootenia spp. indet., Strettonia sp. A, Clavigellus annulus n. gen. and sp., and gen. et sp. incert., the Moroccan Corynexochida comprise only a few forms that are almost exclusively restricted to the High Atlas Mountains. Biogeographical relationships are weak; strong relationships may exist with the faunas of the Shropshire area as already exemplified by some eodiscid and ellipsocephalid taxa.

AbstractMontane biota is vulnerable to climate change, especially in the case of relict species in environmentally extreme areas. The Dades trout Salmo multipunctata is a relict species from the Draa basin, on the southern slopes of the High Atlas Mountains, Morocco. Apart from its genetic and morphological singularity almost nothing is known about this species. We surveyed the whole potential distribution range of the Dades trout and found that only two isolated populations exist (in the Dades and M'Goun catchments), occupying an extremely small range, < 22 km of stream reaches in a narrow altitudinal range (c. 2,150–2,375 m). The species was found more frequently and more abundantly at intermediate elevations within its range, and somatic condition increased with altitude. Climatically suitable areas for the Dades trout will be confined to mountain summits without permanent water bodies by 2070. The Dades trout is a Critically Endangered species in need of active management for its persistence. We propose actions for the long-term conservation of the species, including catchment-scale erosion control, riverbed restoration, local-scale measures to mitigate global warming, and an ex situ breeding programme.
