These are Wadi M’zi (Laghouat region) and Wadi Djedir (Djelfa region). The sampling strategy developed in this work is based on the analysis of the upstream and downstream waters of each watercourse. - 2- - 2+ Eleven physico-chemical parameters (T°C, pH, CE, OD, Cl , SO4 , NO3 , Salinity, Ca , 2+ - Mg and HCO3 ) were measured to establish a diagnosis of the state of health of these aquatic ecosystems. Macroinvertebrates were studied using kick-net sampling at eight study sites. The faunistic inventory of benthic macroinvertebrates identified 37 families, mostly represented by insect larvae (96%). Among these, Diptera and Ephemeroptera were the most dominant orders, with other groups being relatively poorly represented. The results obtained show that the physico-chemical quality of the water is slightly dete- riorated, but the quality is still evaluated as ‘good’ according to the biotic indices 1.

Gazella leptoceros belongs to the tribe Antilopini, sub-family Antilopinae, family Bovidae, which comprises about twenty species in genera Gazella , Antilope , Procapra , Antidorcas , Litocranius , and Ammodorcas (O’Reagan, 1984; Corbet and Hill, 1986; Groves, 1988). Genus Gazella comprises one extinct species, and from 10 to 15 surviving species, usually divided into three sub-genera, Nanger , Gazella, and Trachelocele (Corbet, 1978; O’Reagan, 1984; Corbet and Hill, 1986; Groves, 1988). Gazella leptoceros is either included in the sub-genus Gazella (Groves, 1969; O’Reagan, 1984), or considered as forming, along with the Asian gazelle Gazella subgutturosa , the sub-genus Trachelocele (Groves, 1988).

  • The Tolerance of Atriplex Halimus L. to Environmental Stresses
    Emir. J. Food Agric. 2014. 26 (12): 1081-1090 doi: 10.9755/ejfa.v26i12.19116 http://www.ejfa.info/ REVIEW ARTICLE The tolerance of Atriplex halimus L. to environmental stresses David J. Walker1* and Stanley Lutts2 1Instituto Murciano de Investigación y Desarrollo Agricola y Alimentario, Calle Mayor s/n, La Alberca, 30150 Murcia, Spain 2Groupe de Recherche en Physiologie végétale (GRPV), Earth and Life Institute – Agronomy, ELIA – Université catholique de Louvain, Croix du sud 4-5 bte L7.07.13 à 1348 Louvain-la-Neuve, Belgium Abstract Atriplex halimus L. (Amaranthaceae) (Mediterranean Saltbush) is a perennial, halophytic shrub that possesses the C4 photosynthetic anatomy and physiology. It grows under semi-arid and arid conditions (annual rainfall < 600 mm) from Macaronesia, through the Mediterranean basin countries and into western Asia, being particularly common on saline and degraded soils. Many studies have shed light on the physiological and biochemical mechanisms that, together with the morphological and anatomical features of this species, contribute to its notable tolerance of important abiotic stresses: salinity, drought, extreme temperatures and soil contamination by trace elements. These will be discussed here, highlighting their shared and distinct features. Certain processes are common to two or more stress responses: for example, vacuolar accumulation of sodium and the cytoplasmic accumulation of compatible osmolytes - part of the process of osmotic adjustment - are vital components of the adaptation to drought, salinity and cold. Others, such as oxalate accumulation upon trace elements exposure, seem to be stress-specific, while leaf surface vesiculated hairs (trichomes) and abscisic acid have distinct functions according to the stress.

  • WOOD ANATOMY of CHENOPODIACEAE (AMARANTHACEAE S
    IAWA Journal, Vol. 33 (2), 2012: 205–232 WOOD ANATOMY OF CHENOPODIACEAE (AMARANTHACEAE s. l.) Heike Heklau1, Peter Gasson2, Fritz Schweingruber3 and Pieter Baas4 SUMMARY The wood anatomy of the Chenopodiaceae is distinctive and fairly uni- form. The secondary xylem is characterised by relatively narrow vessels (<100 µm) with mostly minute pits (<4 µm), and extremely narrow ves- sels (<10 µm intergrading with vascular tracheids in addition to “normal” vessels), short vessel elements (<270 µm), successive cambia, included phloem, thick-walled or very thick-walled fibres, which are short (<470 µm), and abundant calcium oxalate crystals. Rays are mainly observed in the tribes Atripliceae, Beteae, Camphorosmeae, Chenopodieae, Hab- litzieae and Salsoleae, while many Chenopodiaceae are rayless. The Chenopodiaceae differ from the more tropical and subtropical Amaran- thaceae s.str. especially in their shorter libriform fibres and narrower vessels. Contrary to the accepted view that the subfamily Polycnemoideae lacks anomalous thickening, we found irregular successive cambia and included phloem. They are limited to long-lived roots and stem borne roots of perennials (Nitrophila mohavensis) and to a hemicryptophyte (Polycnemum fontanesii). The Chenopodiaceae often grow in extreme habitats, and this is reflected by their wood anatomy. Among the annual species, halophytes have narrower vessels than xeric species of steppes and prairies, and than species of nitrophile ruderal sites. Key words: Chenopodiaceae, Amaranthaceae s.l., included phloem, suc- cessive cambia, anomalous secondary thickening, vessel diameter, vessel element length, ecological adaptations, xerophytes, halophytes. INTRODUCTION The Chenopodiaceae in the order Caryophyllales include annual or perennial herbs, sub- shrubs, shrubs, small trees (Haloxylon ammodendron, Suaeda monoica) and climbers (Hablitzia, Holmbergia).

This work aims to (1) explore and compile the unique diversity of floristic and ethnobotanical information on different folk use of plants in this sector and (2) provide a novel insight into the degree of knowledge transmission between the current population and their semi-nomadic forefathers. Ethnobotanical interviews and vegetation inventories were undertaken during 2014–2019. Thirty informants aged from 27 to 84 were interviewed. The ethnobotanical study revealed that the local community of Ouled Dabbeb perceived the use of 70 plant species belonging to 59 genera from 31 families for therapeutic (83%), food (49%), domestic (15%), ethnoveterinary (12%), cosmetic (5%), and ritual purposes (3%). Moreover, they were knowledgeable about the toxicity of eight taxa. Nearly 73% of reported ethnospecies were freely gathered from the wild.

Current data in the Mediterranean basin report up to 16 million hectares of salt soil, 3.2 million of which in Algeria. Germination in vitro of seeds of Atriplex halimus Linnaeus, 1753 (Caryophyllales Chenopodiaceae) in both synthetic media (nutrient agar, and Mueller Hinton) reached rates of 80% at 25 °C and 50% at 5 °C. The taxon shows a good resistance to salt; because of high salinity treatments (500 to 600 meq/l), there is a delay in germination but not complete inhibition of the process.
