We examined adaptive clinal variation in seed mass among populations of an invasive annual species, Echium plantagineum, in response to climatic selection. We collected seeds from 34 field populations from a 1,000 km long temperature and rainfall gradient across the species' introduced range in south-eastern Australia. Seeds were germinated, grown to reproductive age under common glasshouse con...

This study aimed to reveal the interactions of aphids with their primary hosts (pome and stone fruit trees) secondary (herbaceous plants) in around orchards Çanakkale Province northwestern Turkey between April-September from 2020 2021. Thirty-eight aphid species belonging 18 genera two subfamilies, Aphidinae Calaphidinae, Aphididae order Hemiptera were identified on 53 host plants. Also, 92 aph...

Abstract Body size is a trait that can affect plant–pollinator interaction efficiency and plant reproductive success. We explored the impact of intraspecific shifts on interactions between pollinators flowering plants under controlled conditions. considered two development conditions leading to production large small individual flowers Borago officinalis Echium plantagineum . also used natural ...

Vegetation at an abandoned heavy metal bearing mine tailing may have multifunctional roles such as modification of water balance, erosion control and landscape rehabilitation. Research on the vegetation of mine tailings can provide useful information on tolerance, accumulation and translocation properties of species potentially applicable at moderately contaminated sites. Analyses of the relati...

The pyrrolizidine alkaloids previously identified in floral honey attributed to Echium vulgare (Boraginaceae) have been detected (8000-14 000 ppm) in pure pollen collected from the anthers of Echium vulgare. Pyrrolizidine alkaloids and/or their N-oxides were isolated from the aqueous acid extracts of pollen by use of strong cation-exchange, solid-phase extraction and identified by liquid chroma...

OBJECTIVE Fish oil, containing omega-3 fatty acids, attenuates atherosclerosis. We hypothesized that omega-3 fatty acid-enriched oils are atheroprotective through alteration of monocyte subsets and their trafficking into atherosclerotic lesions. METHODS AND RESULTS Low-density lipoprotein receptor knockout and apolipoprotein E(-/-) mice were fed diets containing 10% (calories) palm oil and 0....
