The study comparatively assessed the impacts of farm activities on the abundance and diversity of soil arthropods and soil physico-chemical parameters of the Practical Year Training Programme (PYTP) farmlands, University of Ibadan, South Western Nigeria. Soil arthropods were collected from September, 2010 to February, 2011 in five sampling sites of PYTP farmlands using Berlese Tullgren Extracti...

This paper investigates the spatial heterogeneity of three landscapes along an altitudinal gradient and different human land use. The main aim was the identification of appropriate landscape indicators using different extents. ASTER image was used to create a land cover map consisting of three landscapes which differed in altitude and land use. A number of landscape metrics quantifying patch co...

this study is carried out to estimate the potential evapotranspiration (pet) and crop coefficient (kc) for wheat, bl 3235 variety. a lysimeter is installed to estimate pet at the experimental farm of agricultural research center of bhairahawa, which is located in western part of nepal. the blaney-criddle formula is used to estimate the kc for wheat. the estimated values of pet and kc for wheat ...

introduction: the mortality rate of children is one of the most important indicators to measuring the development of countries. equitable access to pediatricians is an important factor in reducing child mortality and promoting society health. the aim of this tudy was to investiget the inequality and trend of geographic accessibility to pediatricians in iran in the period 2007 to 2013. materials...

Uneven-aged forest management has received increasing attention in the past few years. Compared with even-aged plantations, the complex structure of uneven-aged forests complicates the formulation of management strategies. Forest structural diversity is expected to provide considerable significant information for uneven-aged forest management planning. In the present study, we investigated the ...

The main purpose of this study was to investigate the genetic diversity and population structure of Liza klunzingeri in two regions of the Persian Gulf. In this study, the amplified fragment length polymorphism (AFLP) was employed to analyze population genetic diversity between two populations (Ziyarat & Hendijan). Seven primer combinations (E-AAG/M-CTA, E-ACT/ M-CAA, E-ACT/ M-CTA, E-AAG/M-CTG,...

background & aim: german chamomile is one of the most important medicinal plants. so, assessment of genetic diversity and relationship among the traits are very essential in chamomile breeding programs. determination of the best indirect selection criteria for genetic improvement of essence percent and dry flower yield of german chamomile (matricaria chamomilla l.) populations was investiga...

background and purpose: utilization of health care services and food influence the health status. the food and health care expenditure ratios determine the importance level of them in household's consumption expenditures. we aimed to investigate the iranian rural and urban food and health expenditure ratios inequality during 1998 to 2012. materials and methods: this is a descriptive longit...

breeding for resistance is one of the main approaches to control diseases. in this approach, there is a necessary for existence a sufficient genetic variability of resistance genes. accordingly, assessing the genetic variability in the available germplasm is needed to manage genetic resources. molecular markers are effective tools to investigate genetic diversity for resistance to pathogens. nb...
