Understanding the response of species with differing life-history traits to habitat edges and habitat conversion helps predict their likelihood of persistence across changing landscape. In Brazil's Atlantic Forest, we evaluated frog richness and abundance by breeding guild at four distances from the edge of a reserve: i) 200 m inside the forest, ii) 50 m inside the forest, iii) at the forest ed...

 Over the past 50 years, thousands of rice varieties have been introduced by plant breeders to agricultural communities all over the world. Despite the improvement of attributes such as grain yield and tolerance to biotic and abiotic stresses, a significant portion of farmers still prefer local varieties over the improved cultivars. The main reasons for this perference are the absence of a dire...

AIM This study aims to identify the dominant viral animal pathologies and to list the traditional recipes used by the breeders for their treatment. MATERIALS AND METHODS The method of data collection was based on a retrospective survey. Thus, 787 breeders and agro-breeders scattered in the eight agro-ecological areas of Benin were interviewed using semi-structured questionnaires. RESULTS In...

Eddy-Current Techniques for non–destructive testing and evaluation of conducting material are one of the most known application oriented field in electromagnetics research. According to the Italian PRIN Project (proj. 2009TCLKNF_002), the Authors, in this work, propose a novel approach based on soft computing domain to characterize defects in metallic plates in terms of depth and shape starting...

Need for incorporating expert knowledge into automated systems. In order to better understand Zadeh’s vision of going from fuzzy to computing with words, let us recall the reason why we need to use words in computations and whey fuzzy techniques were invented in the first place. These techniques come from the need for expert knowledge. In many application areas, we rely on experts: medical doct...

the objective of this study was to estimate the effective number of breeders in sarabi cattle population using heterozygote-excess method based on single nucleotide polymorphism markers. data consisted of 20 sarabi cows. snp genotyping was performed using illumina high-density bovine beadchip designed to genotype 777,962 snps. average observed heterozygosity, expected heterozygosity, minor alle...

In this study, age-dependent changes of sperm quality parameters in Rutilus frisii were investigated. Also, fertilization capacity of breeders was tested using two age groups of males (3 and 4 year old breeders) and one female group (i.e. 4 year old breeders). For fertilization trials, the breeders were crossed randomly among age classes. Between the two age groups, spermatological parameters d...

taken were body weight gain (BWG), gain to feed ratio (GF) and percent of foot ash (FA) at 4, 8, and 15 d of age. A significant linear response (P<0.05) was observed in growth performance and FA in birds receiving graded levels of PP at all ages, confirming the sensitivity of the procedure. No significant differences were found in FA percent between groups receiving TP or DP at all ages (13.5 v...
