Trichoderma includes several plant growth and health promoting species. However, information about combined plant growth modulation and biocontrol of plant parasitic nematodes is limited. In this work, the role of indole-3-acetic acid (IAA) produced by T. atroviride and released into the rhizosphere of tomato ( Lycopersicon esculentum L.) in regulating plant growth and its effects on soil nematodes with different lifestyles (i...
Purpose: There is a debate whether microplastic particles released into soils can modify phosphorus bioavailability by altering the soil surface properties. Here, we aim to explore the impact of polyethylene microplastics (PE–MPs) on the adsorption–desorption of inorganic phosphate anions (P) on a volcanic ash soil (VAS). Methods: Batch P adsorption-desorption experiments were conducted in a Chilean VAS with and without 1% (w/...
Notes on Ipomoea (Convolvulaceae) from EcuadorNARA Subscribed
Summary Fieldwork, examination of herbarium specimens and photographic images, supported by molecular sequencing have resulted in the re-interpretation of a number of species of Ipomoea L. found in Ecuador and the recognition of four new species. Ipomoea ophiodes Standl. & Steyerm. is shown to be a distinct species from I. regnellii Meisn. and their contrasting distribution is mapped. An unusual variation in I. setosa Ker Gawl...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
