Arbuscular mycorrhizal fungi (AMF) colonization and spore numbers in the rhizosphere of two fruit species, Paullinia cupana Mart. and Theobroma grandiflorum Schum., growing in a terra firme ecosystem in Central Amazonia were studied from August 1998 to May 2000. Climatic and edaphic factors were also determined to investigate their influence on mycorrhizal variables. Soil pH, Al, Mn and effecti...

Plant communities are coupled with abiotic factors, as species diversity and community composition both respond to and influence climate and soil characteristics. Interactions between vegetation and abiotic factors depend on plant functional types (PFT) as different growth forms will have differential responses to and effects on site characteristics. However, despite the importance of different...

Despite increasing evidence of the importance of intraspecific trait variation in plant communities, its role in community trait responses to environmental variation, particularly along broad-scale climatic gradients, is poorly understood. We analyzed functional trait variation among early-successional herbaceous plant communities (old fields) across a 1200-km latitudinal extent in eastern Nort...

The present study deals with the diversity and distribution of VAMF at different sites with different selected plants. Maximum number of VAMF species were found at site IV (57 species) out of which Glomus species was most dominant (58%), followed by Acaulospora (19%), Scutellospora (8%), Sclerocystis (4.8%) and Gigaspora (1.6%) respectively. In site II 56 species of VAMF were observed with Glom...

Ecological niche modeling (ENM) is a broadly used tool in different fields of plant ecology. Despite the importance of edaphic conditions in determining the niche of terrestrial plant species, edaphic data have rarely been included in ENMs of plant species perhaps because such data are not available for many regions. Recently, edaphic data has been made available at a global scale allowing its ...

Correlation between plant distribution and edaphic factors in coastal plains of Jazan region, Saudi ArabiaA. A. Salman

Fluoride contamination has now become an emerging concern in agroecosystems. A diagnostic survey was conducted across the fluoride (F-) contaminated wetlands of Kuttanad, India with aim to examine influence edaphic factors on F- concentration soils. The soils (Inceptisols) predominantly sandy had a substantial percentage clay and soil characteristics such as bulk density (BD), moisture, tempera...

replacement or even cause community turnover to a fundamentally different assemblage. It is also crucial that future research addresses how temperature, CO2, or edaphic factors may modify plant responses to precipitation variability. As precipitation is coupled with the processes controlling N availability, ecosystem responses to climate change will depend on how the strength of that coupling v...

Soil microorganisms play key roles in ecosystem functioning and are known to be influenced by biotic and abiotic factors, such as plant cover or edaphic parameters. New Caledonia, a biodiversity hotspot located in the southwest Pacific, is one-third covered by ultramafic substrates. These types of soils are notably characterised by low nutrient content and high heavy metal concentrations. Ultra...
