Invasive alien species can have serious adverse impacts on both the environment and the economy. Being able to predict the impacts of an alien species could assist in preventing or reducing these impacts. This study aimed to establish whether there are any life history traits consistently correlated with the impacts of alien birds across two continents, Europe and Australia, as a first step tow...

Agro-morphological characters in 34 populations of Iranian Trifolium resupinatum L. germplasm, were investigated. 24 traits for each accession evaluated according to white clover and forage legume descriptors. Data analyzed by SPSS Excel softwares. Statistical tendency parameters agro-morphological calculated. A cluster analysis based on morphological separate two different groups that one ther...

OBJECTIVES A preliminary study to investigate the orthodontic treatment need and its gender distribution in urban Iranian schoolchildren. STUDY DESIGN A cross-sectional study was carried out at the school premises. SUBJECTS AND METHODS For this survey, 502 subjects attending 6 different schools in the city of Isfahan, Iran (253 females and 249 males, aged 11-14 years) were randomly selected...

In the current paper we investigate whether gender aVects the encoding of leadership behavior. In three studies we found evidence that perceivers had diYculty encoding leadership behaviors into their underlying prototypical leadership traits when the behavior implied an agentic trait and the behavior was enacted by a female. Using a lexical decision making task, in Study 1 we demonstrated that ...

Given finite resources, intense investment in one life history trait is expected to reduce investment in others. Although telomere length appears to be strongly tied to age in many taxa, telomere maintenance requires energy. We therefore hypothesize that telomere maintenance may trade off against other life history characters. We used natural variation in laboratory populations of Atlantic silv...
