In this study, the use of speech-like pragmatic markers in Iranian EFL students’ academic writing was investigated. Speech-like pragmatic markers, such as I think, well, I guess, actually, anyway, anyhow, etc. are linguistic components that are more specific to conversation than writing, and writers may wrongly include them in their academic writing. To examine the students’ use of speech-like ...

Enemy release and biotic resistance are competing, but not mutually exclusive, hypotheses addressing the success or failure of non-native plants entering a new region. Enemy release predicts that exotic plants become invasive by escaping their co-adapted herbivores and by being unrecognized or unpalatable to native herbivores that have not been selected to consume them. In contrast, biotic resi...

Non-native species introductions are widespread and can affect ecosystem functioning by altering the structure of food webs. Invading plants often modify habitat structure, which may affect the suitability of vegetation as refuge and could thus impact predator-prey dynamics. Yet little is known about how the replacement of native by non-native vegetation affects predator-prey dynamics. We hypot...

Extinctions can leave species without mutualist partners and thus potentially reduce their fitness. In cases where non-native species function as mutualists, mutualism disruption associated with species' extinction may be mitigated. To assess the effectiveness of mutualist species with different origins, we conducted a meta-analysis in which we compared the effectiveness of pollination and seed...

This study was a cross-sectional investigation into the request strategies used by Iranian learners of English as a Foreign Language and Australian native speakers of English. The sample involved 96 BA and MA Persian students and 10 native speakers of English. A Discourse Completion Test (DCT) was used to generate data related to the request strategies used by each group. Selection of request s...

ABSTRACT: Transmissible spongiform encephalopathies are neurodegenerative diseases that affect several mammalian species. Bovine spongiform encephalopathy (BSE) is among the mentioned diseases in cattle caused by abnormally fold prion proteins. Polymorphisms of the prion protein gene (PRNP) have been shown to be major determinations for the susceptibility to transmitted perion diseases in human...

BACKGROUND AND AIMS Although urban gardens provide opportunities for pollinators in an otherwise inhospitable environment, most garden plants are not native to the recipient biogeographical region and their value to local pollinators is disputed. This study tested the hypothesis that bumblebees foraging in English urban gardens preferentially visited sympatric Palaearctic-range plants over spec...
