Genetic variation for fitness-relevant traits may be maintained in natural populations by fitness differences that depend on environmental conditions. For herbivores, plant quality and variation in chemical plant defences can maintain genetic variation in performance. Apart from plant secondary compounds, symbiosis between plants and endosymbiotic fungi (endophytes) can produce herbivore-toxic ...

This research was carried out as pod cultivation to evaluate effect of different level of zinc and cadmium on agro physiological traits of Maize via factorial experiment based on completelly randomized design with three replications along 2012-2013. The factors included different level of Zinc (Zn1=0 or Control, Zn2=15 and Zn3=30 mg.kg-1) and Cadmium (Cd1=0 or control, Cd2=10, Cd3=20 and Cd4=30...

Article history: Received 1 March 2014 Received in revised form 20 March 2014 Accepted 28 April 2014 Abstract Introduction: In recent decade, demand for higher education and the factors affecting Academic Performance especially for graduate courses have been increased. So investigating the relationship between emotional intelligence, personality traits and academic performance was the main obje...

Inbreeding is widely hypothesized to shape mating systems and population persistence, but such effects will depend on which traits show inbreeding depression. Population and evolutionary consequences could be substantial if inbreeding decreases sperm performance and hence decreases male fertilization success and female fertility. However, the magnitude of inbreeding depression in sperm performa...

Combat traits are thought to have arisen due to intense male-male competition for access to females. While large and elaborate weapons used in attacking other males have often been the focus of sexual selection studies, defensive traits (both morphological and performance) have received less attention. However, if defensive traits help males restrict access to females, their role in the process...

The main objective of this ex post facto study is to compare the differences in cognitive functions and their relation to schizotypal personality traits between a group of unaffected parents of schizophrenic patients and a control group. A total of 52 unaffected biological parents of schizophrenic patients and 52 unaffected parents of unaffected subjects were assessed in measures of attention (...

Mechanistic animal growth models can incorporate a description of the genotype as represented by underlying biological traits that aim to specify the animal's genetic potential for performance, independent from the environmental factors captured by the models. It can be argued that these traits may therefore be more closely associated to genetic potential, or components of genetic merit that ar...

BACKGROUND The presence of attention-deficit/hyperactive disorder (ADHD) symptoms and impaired attention performance are commonly noted in individuals with autism spectrum disorder (ASD). However, little is known about attention performance in their unaffected siblings. This study aimed to investigate the ADHD-related traits and attention performance in unaffected siblings of probands with auti...
