This pioneering work is the first to document the aquatic avifauna community of the Wadi Djedi in the Ziban region in southeast of Algeria. We present results obtained through the monthly counts of waterbirds conducted from September 2013 to September 2016. On this wetland we recorded 36 species of water birds representing 11 families. The Anatidae family was the most numerous, with 11 species. From among all the species, 18 were wintering species, nine were visitors, eight were sedentary breeding species (including the ruddy shelduck Tadorna furruginea and Kentish plover Charadrius alexandrines) and one species was migratory nesting (the white stork Ciconia ciconia). Two species (the teal marbled Marmaronetta angustirostris and ferruginous duck Aythya nyroca) are listed as Vulnerable on the IUCN Red List of endangered species.

This study investigated insect diversity of olive (Olea europaea Linnaeus (Oleaceae)) groves grown in arid and semiarid climates in northeastern Algeria. Using several sampling techniques, a total of 1326 insect specimens were collected and identified into 151 species, 124 genera, 65 families, and 10 orders. Hymenoptera and Coleoptera were quantitatively the most abundant, whereas the dominant functional feeding groups were phytophages then predators. The entomofauna included several olive pests such as Bactrocera oleae (Rossi) (Diptera: Tephritidae), Parlatoria oleae (Colvée) (Hemiptera: Diaspididae), Euphyllura olivina (Costa) (Hemiptera: Liviidae), and Liothrips oleae Costa (Thysanoptera: Phlaeothripidae). Although insect diversity parameters recorded for both observed and expected species richness were higher in olive groves grown under semiarid compared with arid climate, the completeness rate of species richness obtained using the nonparametric incidence estimators was higher in arid olive groves. Generalised linear models showed that the number of individuals and species richness varied significantly between climates (P < 0.01), whereas the variation of the rest of diversity parameters was not significant. Diversity traits of insect assemblage of each climatic region were positively correlated. Besides, the Mantel permutation test revealed similar patterns (r = 0.91, P < 0.0001) between correlation matrices of the two climates. When increasing the number of samples, species richness extrapolation revealed that diversity is expected to increase by 130% in olive groves grown under arid climate and 93% in semiarid climate. These increases are related to continuous appearance of rare and scarce insects as demonstrated by species rarefaction curves. Even with high evenness values of insect communities, similarity was low between climate indicating the rarity and scarcity of populations.

Nuestro estudio muestra un inventario de roedores del noroeste de Argelia. Tas especies se capturaron en dos regiones: Taouziant (Montañas Aurès ) y Bouchagroune (oasis de Ziban). El periodo de muestreo duró diez mees en cada lugar: en Taouziant de febrero a nobiembre de 2014 y en Bouchagroune de septiembre de 2013 a junio de 2014. El método de trampeo en línea fue llevado a cabo mediante 40 jaulas-trampas instaladas en las regiones de estudio. Se capturaron ocho especies, que pertenecen a tres subfamilias y seis géneros. Tres especies se distribuyen en las dos regiones Rattus rattus, Mus musculus y Gerbillus amoenus. Tres especies se capturaron en los campos de cereal de Taouziant ( Rattus norvegicus, Meriones shawii y Jaculus jaculus) y dos especies en el palmeral de Bouchagroune (Psammomys obesus y Gerbillus gerbillus) Our study presents an inventory of rodents in Northeast of Algeria. The species were captured at two regions: Taouziant (Aurès Montain) and Bouchagroune (Ziban oasis). The sampling period takes ten months at each site: in Taouziant between February to November 2014 and in Bouchagroune, from September 2013 to June 2014. The method of trapping online was performed using 40 wire traps installed at the studied regions. Eight species were captured. They belong to three subfamilies and six genera. Three species occur in the two regions: Rattus rattus, Mus musculus and Gerbillus amoenus. Three species were captured in Taouziant cereal fields ( Rattus norvegicus, Meriones shawii and Jaculus jaculus) and two species were found in Bouchagroune palm grove (Psammomys obesus and Gerbillus gerbillus)
