    Effect of cold and scarification on seeds germination of pistacia atlantica L. for rapid multiplication
    (Pakistan Botanical Society, 2014) Chebouti-Meziou, N.; Merabet, A.; Chebouti, Y.; Bissaad, Fatima Zohra; Behidj-Benyounes, N.; Doumandji, S.
    This study was carried out to determine the effects of mechanical scarification and cold treatment of seeds at + 4°C before sowing seed of Pistacia atlantica. In these cases, the durations at cold temperature, which have been taken into account, are successively 60, 50, 40, and 30 days. After these periods, the rate of germination and the speed of germination are calculated every 4 days. The rates of germinations concerning the not scarified seeds having undergone a cold treatment lasting 50 days are the most important that is a value of 39% from the 09-05-2010 until the 29-05-2010. The speed germination is maximum that is 89 germinated seeds /4 days. In addition this same rate reaches a maximum of 70%. Concerning the pistachio tree seeds of the atlas treated mechanically with duration of cold treatment at + 4°C during 30 days. For the same category of seed the speed of germination is maximum that is 214 seeds/4 days. Thus the scarification and the 30 days stay are the fastest means which allow to obtain the seedlings of pistachio tree in a rather short time

    Feeding ecology of the vulnerable aoudad (Ammotragus lervia) in north-western Sahara
    (John Wiley and Sons Inc, 2023) Bounaceur, Farid; Benamor, Naceur; Bissaad, Fatima Zohra; Lasgaa, Faten; Baghadid, Sabah; Rezigua, Faiza; Aulagnier, Stéphane
    The feeding ecology of the aoudad (Ammotragus lervia) was investigated for the first time in north-western Sahara, Djebel Antar (Bechar province, Algeria), from autumn 2015 to summer 2016. Microhistological analyses of faeces revealed an annual diet composed of 23 identified taxa belonging to 16 plant families. The highest species diversity was recorded in spring and summer (23 species), despite a marked consumption of two species: Vachellia tortilis (17.7%) and Avena sterilis (14.0%); diet diversity was lower in autumn and winter (16 species), including mainly Teucrium polium (14.7%, 21.0%) and Gymnocarpos decander (19.7%, 10.0%). The main plant parts consumed during these seasons were stems (77.7%, 65.3%), while leaves and inflorescences were mostly consumed during spring and summer (54.7%, 52.3%). Forbs dominated the aoudad's diet, with 46.3% average relative abundance, including mainly T. polium, Limoniastrum feei, and Chrysanthemum macrocarpum. Woody plants including mainly V. tortilis and G. decander accounted for 33.3% (50.0% in autumn), and grasses including A. sterilis and H. murinum for 20.4% (32.0% in summer). Based on this diet, A. lervia can be classified as a “generalist mixed-feeder.”

    Is there a future for the last populations of aoudad (Ammotragus lervia) in northern Algeria?
    (Zoological Society of Pakistan, 2016) Bounaceur, Farid; Benamor, Naceur; Bissaad, Fatima Zohra
    Very small natural populations of aoudad or barbary sheep remained in northern Algeria. Areas where aoudad has been previously reported were surveyed from 2012 to 2015 in spring and autumn. Animals were recorded at only four localities in the north-eastern part of the mountains, south of Tebessa, Batna, M’Sila and north east of Biskra, and only one in the western part south of Tiaret. Sighted groups included 1 to 11 individuals. The main threats to this species are reported, captive breeding is suggested as a tool for conservation

    Monitoring threatened ungulates (Gazella cuvieri and Ammotragus lervia) in the semi-arid North African Nador Mountains
    (Verlag der Oesterreichischen Akademie der Wissenschaften, 2022) Bounaceur, Farid; Boualem, Aoued; Abdi, Abdelkader; Bissaad, Fatima Zohra; Kaddouri, Mohamed Amin; Djilal, Mohamed; Zenati, Azeddine; Belgarssa, Yahia; Aulagnier, Stéphane
    Cuvier’s gazelle (Gazella cuvieri) and aoudad (Ammotragus lervia) are listed as Vulnerable in the IUCN red list, and any population should be the subject of scientific attention. Both ungulates were monitored for a year in the Nador Mountains (western Algeria). This is the first record of aoudad in this part of Tiaret province. Both species are partly sympatric. However, the aoudad was sighted only in small numbers in the roughest valleys in the north. The gazelle population is larger, but with few juveniles. The future of these wild ungulates is therefore worrying, and new conservation measures are required, including protecting this area
