1. Introduction
North Africa biogeography is considered to be
particularly complex, because it is located in very
complex orographic structures that evolved
mainly during the Neogene, and can become a
prerequisite to the fragmentation of the range of
different species, leading to high biodiversity
endemic taxa [1, 2, 3]. Among these ecological
barriers such as mountains, which are considered
as an important factor leading to fragmentation of
the range of different species [4].
The genus Trapelus Cuvier, 1817 [5] in the
agamid subfamily, Agaminae was resurrected by
it has a broad distribution across northern Africa
into the Middle East and Asia [6, 7]. In the
Saharo-Sindian, this genus currently consists of
15 species, with six species occur in Africa [7],
i.e, Trapelus pallidus (Reuss, 1834): Egypt,
Republic of Djibouti, Jordan [8, 9]; Trapelus
savignii (Duméril & Bibron, 1837): eastern
Egypt[10]; Trapelus mutabilis (Merrem, 1820):
northern Africa[11]; Trapelus tournevillei
(Lataste, 1880) [12]: Algeria and Tunisia;
Trapelus schmitzi (Wagner and Böhme, 2007):
Algeria; Chad[13] and Trapelus boehmei
(Wagner, Melville, Wilms and Schmitz, 2011) :
north-western Africa[7].
Therefore, Algeria counts four Trapelus
species: T. tournevillei, T. schmitzi, T. boehmei
El bouhissi et al / Alger. j. biosciences 03(02) (2022) 085-090 86
and T. mutabilis [14, 15, 16, 17, 18].
According to the IUCN red list all this species
are ranked least concern species (LC),
characterized by a wide range, except T. schmitzi
have an unknown status (DD [14, 15, 16, 17, 19].
However, in Algeria, two species, i.e, T.
tournevillei and T. mutabilis are protected by
Algerian flat (12-235) of 24 May 2012.
The objective of this note is to provide a new
locality of this species in the Sahara of the
Southwest of Algeria at Tindouf, situated at
Tindouf region at more than 200Km east from the
distribution range [16].
2. Materials and methods
2.1. Study area
Tindouf region is located in the Southwestern
part of Algeria and covers an area of 158,874
km2, representing 6.67% of the total area of the
National territory [20]. This region is
characterized by hyper arid climate with an
average annual rainfall of 35mm [21] (Fig. 1).
This region is relatively homogeneous. It is
characterized by the extension of the Tabular
platform of the Hamadas [22]. The average
altitude is around 450 m. Overall, the topography
is flat with low slopes ranging between 0 and 3
% [23].
2.2. Reptile sampling
We recorded species based on transects from
10 to 20 km in open areas, each transect was
divided to 150 m of observation segment because
reptiles are small animals with limited ranges,
and deserve a good concentration in observation,
further, we searched animal species in cavities
and under rocks [24, 25].
3. Results and Discussion
As part of the Herpetological inventory in the
region of Tindouf. The first observation of this
species was on July 23, 2022. A single individual
of Trapelus boehmei male, with bluish coloration
on the throat (nuptial coloration) , measures more
than 20 cm in length, taking sunbathes at
10:15pm (Fig. 3a, b), where the temperature was
estimated at 36 C°.
The type locality is a Wadi bed,
characterized by rocky plateau (Reg) with some
plants, i.e, Acacia raddiana, Retama raetam,
Tamarix gallica (Fig. 2).

3.2. Description
Trapelus boehmei has a relatively long head
tapering abruptly at the nose. Body escalation is a
matrix of small, feebly keeled and homogeneous
scales intermixed with larger keeled scales,
which usually differ in coloration from the matrix

scales in breeding coloration of adult males.
Males have bluish coloration on the throat and
body when in nuptial coloration, and a small
gular pouch [7].
3.3. Biogeographical and ecological
The range of this species is confirmed in the
northwest of Africa in Algeria, Mauritania and
Niger, with an uncertain distribution in Mali,
Tunisia and Western Sahara.
As for Algeria, the distribution is confirmed in
the High Plateau, from M’sila to Naâma and
Tlemcen-south, with an uncertain presence from
Batna, extends to the entire east of Algeria
between El Tarf and Tebessa (Fig.01) [7].
Recently, many studies have been
concentrated in desert regions, which has led to
the discovery of several new expansion sites,
among which the current study, and others
researches like El-Menia [26], El Oued and
Touggourt [18, 27].
The presence of the Trapelus boehmei in
Tindouf is interesting and it i suggest that further
research at different seasons, in order to learn
more about the distribution of this species and
others of the genus Trapelus.

The Rough Bent-toed Gecko Cyrtopodion scabrum (Heyden,1827) was recently recorded in Algeria, from the east part of countries. In this note, another new locality of this species in the central Algeria (Ghardaïa region), situated at 450 km west form the last locality, based on one specimen fond in Bord of Sebkhet. C. scabrum is listed as an invasive species and it was reported as a desert species, in our finding it was recorded in an important wetland (Sebkhet El Melah) which is classified in the Ramsar list in 2004, this statement proves once again the ecological plasticity of this species.

The present study was based on the observations and captures of reptiles in the Northern Algerian Sahara (2011-2013). Thirty homogeneous stations, representing the principal landscape units and ecosystems, were investigated. The studied ecosystems were the erg (sand dunes), saline areas (Chott, Sebkha), reg, palm groves, and urban sites. We have identified 30 species (20 Saurians, 9 Ophidians and one Testudines). The inventory concerns 2 orders (Testudines and Squamata), 12 families and 22 genera. Among the identified species, seven were protected in Algeria, 5 species (Tarentola deserti, Tarentola neglecta, Trapelus tournevillei, Hemorrhois algirus and Natrix Maura) are endemic according to U.I.C.N. The number of species in the different IUCN Red List Categories shows that 28 are assessed as Least Concern, one specie is considered to be Data Deficient (Scincopus fasciatus) and One species is listed as near threatened (Uromastix acanthinurus). The species distribution according to the habitat types showed that he erg was the most populated ecosystem with the highest number of captured individuals (403 individuals). The highest species richness was noticed in the palm groves with 19 species as well as the Shannon diversity index (3.34). The evenness is at its highest in the saline and the urban site with 0.89 and 0.81. The correspondence factorial analysis showed that some species were characteristic of habitats such as Tarentola neglecta and T. deserti which are detected as a specific species of the urban sites and the palm groves, while Scincus was a specific species of the Erg. The generalized linear model showed that the geographic coordinates (altitude, longitude and latitude), the spatio-temporal factors (habitat type; climatic period) and human pressure have significant effects on the abundance variation of the studied reptiles.

Analysis of biological diversity in woody habitats is crucial for the implementation of suitable conservation policies. We carried out monthly field visits using the point count method for avian species and walked-transect surveys for mammals and reptiles from January 2018 to December 2021 in Fez, El Hajeb and Sefrou, central Morocco. The studied sites were steppes dominated by Chamaerops humilis. A total of 90 bird, 12 mammal and 8 reptile species were documented. Furthermore, two species of conservation concern, i.e., the vulnerable European turtle dove Streptopelia turtur, and the endangered Egyptian vulture Neophron percnopterus were recorded. The documented species use Chamaerops humilis for breeding (support for nesting birds), foraging (via fruits) and wintering purposes. These findings are the first results related to animal biodiversity in Chamaerops humilis shrublandsin Morocco. However, other aspects, including the nutritive quality of Chamaerops humilis fruits for wintering animals, need further studying. Likewise, the threatening factors that might negatively influence North African forests require urgent studying.

Diversity and distribution pattern of scorpions from the Ouarsenis massif of Tissemsilt, NorthWest Algeria. Biodiversitas 23: 2444-2450. Ecological barriers such as mountains are important factors leading to fragmentation of the range of different species and the important cause of vicariance events. Ouarsenis massif (Tissemsilt, NorthWest Algeria) is an important protected Park. This paper presents a preliminary study of scorpion diversity and assesses this biodiversity change in this Mountain range along a gradient of many ecological descriptors, including elevation, vegetation cover, slope, and soil types. During 2020 and 2021, we sampled 179 specimens of scorpions by direct hunting from the eight biotopes in Ouarsenis massif. Only adult individuals were used for identification after being killed and kept in 70% alcohol. Based on morphological criteria, we identified eight species distributed in two genera and two families. The family Buthidae was represented by five species with the highest relative abundance (RA) was Buthus tunetanus (RA= 47.49%). Furthermore, the family Scorpionidae was represented by three species with the highest RA was Scorpio maurus (RA=25.14%). The Shannon index (H' = 2.71 bits) indicated that Ouarsenis massif region had a high level of scorpion diversity and the value of evenness (E = 0.90) reflected the high equilibrium between the effectiveness of sampled species. The main determinant descriptor of scorpions distribution was the elevation and soil types, while the vegetation cover could be considered an ancillary factor.

L’Algérie est un cas d’école en matière d’ignorance en biodiversité. A ce jour, on ne dispose d'aucun inventaire complet pour aucun taxon ni aucun atlas à l’échelle du pays ! Pourtant, l’Algérie est d’une grande importance pour la biodiversité mondiale. La façade littorale de l’Algérie fait partie du hostpot de biodiversité mondial qui est le pourtour méditerranéen et compte plusieurs points rouges de biodiversité régionaux. Par ailleurs, la partie saharienne contient une diversité d’organismes endémiques adaptés aux fortes conditions de sécheresse. Les autorités algériennes déploient un projet ambitieux pour la conservation en fixant 50 % de la surface du pays comme objectif pour les aires protégées ! Mais, l’emplacement de ces aires protégées et leur gestion n’obéit pas à des critères basés sur une bonne connaissance de la diversité, mais sont plutôt panifiés à dire d’expert. L’objectif général de cette thèse c’est l’étude de la distribution de l’ignorance en biodiversité en Algérie en se concentrant sur les « Linnean, Wallacean et Darwinian Shortfalls » et de contribuer à les réduire. J’ai consacré un chapitre qui a pour but de réduire le Linnean Shortfall en proposant 1) une première checklist des reptiles et amphibiens d’Algérie qui est le fruit d’un examen précis des publications scientifiques sur ces taxons en Afrique du Nord. 2) une première pré-évaluation des statuts de conservations des reptiles et amphibiens d’Algérie pour la production de la première liste rouge nationale. La deuxième partie de ce manuscrit traite la question de l’ignorance de la distribution géographique des espèces. Le but de cette partie est de cartographier l’ignorance qui est la différence entre la diversité la richesse spécifique attendue et la richesse spécifique observée. La richesse spécifique attendue a été modélisée avec deux approches : 1 l’utilisation des modèles de niches avec la méthode de maximum d’entropie (MaxEnt) pour prédire les habitats favorables pour chaque espèce puis additionner les différentes couches binaires de présence des espèces pour calculer la richesse spécifique. 2) l’addition des couches des aires d’occurrences des espèces construite par la méthode du minimum convex polygon pour produire la carte de distribution de la richesse spécifique. Les deux approches ont montré la même tendance à l’échelle nationale, c’est-à-dire la concentration des zones les plus riches sur le long de l’Atlas Saharien et des hauts plateaux qui sont la zone de transition entre le Sahara et la partie méditerranéenne de l’Algérie. L’opposition de la partie saharienne globalement pauvre en espèce et la moitié nord plus riche. En fin, les massifs sahariens du Hoggar et Tassili forment une zone très distincte avec une richesse nettement supérieure par rapport au reste du Sahara. Pour ce qui est des lacunes, dans la Partie nord, la Kabylie, le parc national d’El Kala et la région d’Oran sont assez bien prospectées. Dans le Sahara, seuls quelques points sont assez bien prospectés comme Biskra, Béchar et quelques zones du Hoggar et Tassili. En fin, la troisième partie porte sur la distribution des lignées génétiques dans le Maghreb. Les objectif de cette partie est localiser les zones de sutures entre les lignées génétiques divergentes des populations de l’est et de l’ouest du Maghreb et d’essayer de comprendre les mécanismes qui ont conduit à ce patron de diversité génétique. Pour répondre à ces questions, j’ai effectué une phylogéographie comparées sur 11 espèces de reptiles et amphibiens à distribution continue et large dans le Maghreb. Deux zones de sutures ont été identifiées : une zone à la frontière de l’Algérie et du Maroc, l’autre EN Kabylie à l’ouest de la vallée de la Soummam. Les divergences entre les clades est et les clades ouest ont eu lieu entre la période pré-messinienne jusqu’au à la limite plio-pleistocène et se seraient maintenues dans des refuges climatiques à l’est et à l’ouest du Maghreb.
French zoologist and naturalist Georges Cuvier (1769–1832), one of the most eminent scientific figures of the early nineteenth century, is best known for laying the foundations of comparative anatomy and palaeontology. He spent his lifetime studying the anatomy of animals, and broke new ground by comparing living and fossil specimens - many he uncovered himself. However, Cuvier always opposed evolutionary theories and was during his day the foremost proponent of catastrophism, a doctrine contending that geological changes were caused by sudden cataclysms. He received universal acclaim when he published his monumental Le règne animal, which made significant advances over the Linnaean taxonomic system of classification and arranged animals into four large groups. The sixteen-volume English translation and expansion, The Animal Kingdom (1827–35), is also reissued in the Cambridge Library Collection. First published in 1817, Volume 3 of the original version covers molluscs, arachnids and insects.
Cyrtopodion scabrum, an invasive gecko, was detected 2400 km east of its current range in Algeria and in North and West Africa (Egypt excluded). During herpetological surveys conducted from 2009-2018, 40 individuals (20 females and 20 males) were caught by hand in urban sites and in oases of date palm (Phoenix dactylifera). The morphometric traits measured on caught individuals were almost identical to specimens from its native range. The snout-vent length was 4.53 ± 0.63 cm in males and 4.56 ± 0.77 cm in females. The hind-limbs (average: 2.3 ± 0.35 cm, range: 1.7-2.87 cm) were slightly larger than the forelegs (average: 1.64±0.27cm, range: 1.2-2 cm). The number of supra- and infra-labial scales was 9-10. The statistical tests showed that the variation in biomorphometrics between the two sexes was not significant. Cyrtopodion scabrum is an alien invasive species for North Africa and Algeria. Among the main factors explaining this species invasion in the northern Sahara are the import of agricultural products linked principally to potato cropping activities.
