chukar partridge raising is a profitable business. new feed additives of plant origin may be an alternative to antibiotic growth promoters. this study was carried out to determine the effect of different levels of pistacia atlantica oil on performance and pathological conditions in chukar partridge. one-day-old chukar partridge chicks were assigned to three dietary treatments of 40 birds each. ...

Endophytic fungi live inside plant tissues and increase their resistance to abiotic biotic factors. Our work is concerned with interannual variations of mycoendophyte diversity leaves Pistacia atlantica Desf. dayate Aiat, in the region Laghouat (Algeria) this for spring 2013 2016. The morphological identification revealed presence 26 fungal genera. difference very significant between two years ...

A new species of spider crab, Naxia atlantica n. sp., is described and illustrated from deep waters off São Paulo (southeastern Brazil). The new species can be separated from its congeners by a suite of characters including shapes of the propodi of the walking legs, rostrum and basal antennal article. This is the first record of the genus outside southern Australia and New Zealand. 

The title compound, C(17)H(22)O(2), was semi-synthesized from a mixture of α-atlantone (Z) and α-atlantone (E), which were isolated from the essential oil of the Atlas cedar (cedrus atlantica). The mol-ecule consists of fused six- and seven-membered rings. The seven-membered ring is in a screw-boat conformation.

Climate change is one of the most significant challenges to biodiversity conservation, particularly in dry tropical islands, such as Cabo Verde archipelago where only three endemic tree taxa occur – Dracaena draco subsp. caboverdeana, Phoenix atlantica and Sideroxylon marginatum all classified threatened. The main goal this study was predict possible shifts climatically suitable habitat ranges ...

We studied hydraulic traits of young plants of the Mediterranean cedar species Cedrus atlantica (Endl.) G. Manetti ex Carrière (Luberon, France), C. brevifolia (Hook. f.) Henry (Cyprus), C. libani A. Rich (Hadeth El Jebbe, Lebanon) and C. libani (Armut Alani, Turkey). With an optimum water supply, no major differences were observed among species or provenances in either stem hydraulic conductiv...

Three Atlantic Forest endemic species of emerald dragonflies the genus Navicordulia Machado & Costa, 1995 are reviewed through a morphological comparative analysis. All name-bearing types and additional specimens atlantica-complex—Navicordulia atlantica 1995, mielkei miersi 1995—were investigated to assess their taxonomic nomenclatural status. Based on our results hypothesis these three nomina ...
