Abstract

The objectives of the study were to identify the physiological behavior in soil and plants, to study the anatomical characters as well as the correlations of soil analysis with chemical estimates and amino acids in T. polium plants during spring and autumn seasons in Wadi El-Arbaeen at South Sinai and in Wadi El-Obayed at Marsa Matruh, Egypt. The location, sites and depths in soil properties; locations and seasons in plant chemical compositions and amino acids as well as their interactions were showed significant (P < 0.05 or 0.01) effects.

The pH values were higher than 7 in the two depths at the three streams during the two locations. The values of water content, EC, Cl–, Ca2+, Na+ and K+ in soil at the two depths in three streams in Wadi El-Obayed were higher than in Wadi El-Arbaeen. As for plant chemical compositions, succulence ratio, total protein and Mg2+ concentrations in the spring season were higher than in the autumn season under the two studied Wadis. Most concentrations of plant analysis and amino acids concentrations and leaf anatomical characters of T. solium in the Wadi El-Arbaeen were higher than in the Wadi El-Obayed. Proline ranks first in accumulation in T. polium at the spring and autumn seasons, which contributed about 25% and 26% of the total amino acids during Wadi El-Arbaeen and Wadi El-Obayed, respectively. Anatomical characters in T. polium exhibited significant differentiation under Wadi El-Arbaeen and Wadi El-Obayed locations. Positive correlation coefficients were found between water content, EC, pH, Na+, Mg2+, Ca2+ and Cl– in the soil and K+, Na+, Mg2+, total protein; total carbohydrate and succulence ratio in the plants under the two Wadis. Most soil analysis were showed positive correlated with most amino acids during the two locations.

Sci. 16(1), 61-71, January 2020.english language editingJBES welcome all respective authors to submit their research paper / manuscripts, thesis paper in the field of Environmental Sciences, Biology, Biodiversity,  Species diversity, Ecology, Taxonomy and many more via online submission panel

Antlions (Neuroptera: Myrmeleontidae) are insects that larvae prefer in dry habitats. They are less known in the Afro-tropical zone and the present study was investigated to determine their diversity in the high Sudano Guinean and Sudano sahelian savannahs of Cameroon.

About 11% of the lands covering Iranian territory are assigned to agriculture, so as to fulfil nutrient needs of about 75% of the Iranian population. Meanwhile, wheat production is seen to enjoy a highlighted position. Within the recent past, a great deal of discussion has been dedicated to the subject matter of wheat loss in the course of the chain from agricultural production to consumption, so as to find solutions for attenuating such a loss, especially in the course of harvesting the crop using combine harvester. Even though some reports indicated such losses to be as much as 20%, the corresponding figures to industrial countries typically range within 2-5%. Grain loss monitoring system is one of the ways to measure the amount of the grain loss in the combine harvesters. The piezoelectric sensors with great sensitivity are usually utilized in this kind of systems. In order to measure grain loss incurred by cleaning unit of a combine harvester, five piezoelectric sensors are used at an approximate spacing of 14cm. TL072 and LM311N were used to amplification of the recorded signal. In order to evaluate the sensor performance, the device was subject to in-lab investigations indicating the best results at the calibration factor (CF) of 5.

Abstract

Habitat complexity of wetlands supports diverse organisms where aquatic insects control the structure and dynamics of the food web. In the present study, biodiversity features of aquatic insects are dealt with reference to their taxonomic and functional diversity. Sampled specimen were assigned a habitat and ‘functional feeding group’ as proposed by Cummins and Klug (1979) .
