Amphimela raydahensis sp. nov. is described from Garf Raydah Nature Reserve (Abha, Asir Province), southwestern Kingdom of Saudi Arabia. This species was collected using black light traps at different elevations dominated by cacti and wild olive trees. This is the first confirmed species of Amphimela known from the Arabian Peninsula.

The compensation heat pulse method is widely used to estimate sap flow in conducting organs of woody plants. Being an invasive technique, calibration is crucial to derive correction factors for accurately estimating the sap flow value from the measured heat pulse velocity. We compared the results of excision and perfusion calibration experiments made with mature olive (Olea europaea L. 'Manzani...

Endophytes have an intimate and often symbiotic interaction with their hosts. Less is known about the composition and function of endophytes in trees. In order to evaluate our hypothesis that plant genotype and origin have a strong impact on both, endophytes of leaves from 10 Olea europaea L. cultivars from the Mediterranean basin growing at a single agricultural site in Spain and from nine wil...

ABSTRACT- The aim of this study is economic analysis of supplemental irrigation (SI) for rain-fed fig trees in the south of Iran, with and without micro-catchment water harvesting systems (MCWHS). Under no MCWHS, by decreasing about 55 % of applied water, the fig yield decreased about 28% and net income increased twice compared with the maximum yield condition. In general, the ...

One of the objectives of conservation agriculture to reduce soil erosion in olive orchards is to protect the soil with cover crops between rows. Andalusian and European administrations have developed regulations to subsidise the establishment of cover crops between rows in olive orchards. Current methods to follow-up the cover crops systems by administrations consist of sampling and on ground v...

The genus Xiphinema includes a remarkable group of invertebrates of the phylum Nematoda comprising ectoparasitic animals of many wild and cultivated plants. Damage is caused by direct feeding on root cells and by vectoring nepoviruses that cause diseases on several crops. Precise identification of Xiphinema species is critical for launching appropriate control measures. We make available the fi...

26 This narrative review compares evidence from experimental, epidemiological and 27 clinical studies of the health benefits of rapeseed (Canola) oil and olive oil in order to 28 assess if rapeseed oil is suitable as a sustainable alternative to olive oil as part of a 29 Mediterranean-style diet in countries where olive trees do not grow. From 30 epidemiological studies, the evidence for cardio...
