In this study, a landmark-based geometric morphometric analysis was carried out on three honeybee subspecies: Apis m. intermissa and A. sahariensis collected from Algeria, and, as reference, capensis South Africa. The aim of study to discriminate subspecies by patterns shape variation fore hind wings. A total 540 wings 270 workers were analyzed. Our results revealed very high cross-validation classification rates (96.7% based wing 99.6% the combination forms respectively). Discrimination...
The biodiversity of Apis mellifera intermissa in the northern parts Algeria is analysed using geometric morphometric investigations workers' forewing variability. A total 3400 worker bees was collected from hived colonies throughout Algeria, between 35°19′N–37°01′N and 00°54′W–8°06′E. Results showed a clear differentiation main three ecological regions. Differences involve mostly shape, while size contribution generally weak. Within regions, shape variability apiaries does not appear related...
Abstract. Heramza K, Barour C, Djabourabi A, Khati W, Bouallag C. 2021. Environmental parameters and diversity of diatoms in the Aïn Dalia dam, Northeast Algeria. Biodiversitas 22: 3633-3644. Diatoms have long been used as biological indicators quality aquatic environments due to their important capacity respond environmental change. As this flora has very little studied Algeria, present study aimed monitor Spatio-temporal dynamics at dam (north-eastern Algeria) determine main abiotic...
A survey of immature Culicidae was conducted in diverse habitats Souk-Ahras province (Northeast Algeria) between December 2018 and November 2019.Altogether, 12,861 specimens were collected identified.Nineteen species mosquitoes, belonging to two main subfamilies viz.Culicinae (accounts for 84.21 %) Anophelinae (as 15.79 %), under 5 genera (Culex, Culiseta, Anopheles, Aedes Uranotaenia).Among identified species, six mentioned the first time Souk-Ahras.The predominant total mosquito fauna Cx....
The composition and distribution of diatoms were studied using a biweekly sampling performed in three representative stations the Mellah Lagoon (South Western Mediterranean, Algeria), during 2016.In total, 160 species -belonging to centric (52 species) pennate (108 -were inventoried.The relative abundance forms (67.50%) is clearly higher compared (32.50%).The blooms are represented by 3 species: Chaetoceros constrictus Gran, 1897 with up 15000 cells.L -1 (end May), sp. 178320 (early...
Understanding the ecology and spatio-temporal distribution of mosquitoes is essential to implementation management programs. Periodic spatial investigations mosquito species are critical for vector-borne disease monitoring. Bimonthly collections immature from sixteen habitats in four districts Tébessa Province (Northeast Algeria) were reared fourth instar or adult stage identification during June 2019 May 2020. Ten identified 69,974 specimens, belonging genera Culex, Culiseta, Aedes,...
Comparative study was carried out on classical morphometric reproductive and biochemical parameters concerning populations of Atyephyra desmaresti sampled in northeast Algeria: the mouth Mafragh River with El Battah (site 1) is located Annaba's Gulf, Oubeira 2) Tonga 3).Lakes are Kala National Park.Principal component analysis revealed a very significant correlation between characteristics A. each site.Growth process seems relatively similar analyzed population except some abnormal values...
Objectives/Methods: The effects of human and agricultural activities on waters Messida canal link up Tonga Lake (RAMSAR site) with the Mediterranean Sea were assessed by determining fluctuations indicator fecal pollution physico-chemical parameters. distribution bacterial pathogens was also monitored. Findings: Most hydrological parameters show large between sampling sites seasons (P<0.05). In spring summer, chlorophyll-a, orthophosphate, BOD5 values abundant compared to winter values....
The aim of the present work is scientific evaluation an Algerian endemic taxa (Hypochaeris laevigata var.hipponensis Maire) widely used in folk medicine.For this objective, active compounds, mineral element composition and antioxidant effects three different extracts prepared from leaves were determined.Essays started by a phytochemical screening, followed elements determination leaf extract preparation using organic solvents.The concentration polyphenols, flavonoids, tannins, flavanols...
The main objective of this study was to assess the impact environmental pollution on gastropod Stramonita haemastoma by examining various physiological and biochemical parameters. Trace metal elements (TME) were measured in snail’s foot. Over a one-year period from 2013 2014, investigated variations reduced glutathione, malondialdehyde, metallothionein, glutathione S-transferase, Acetylcholinesterase catalase activities foot at three different sites. results showed spatiotemporal...
