Partial mycoheterotrophy: a common strategy in arbuscular mycorrhizal plants?

open access: yesNew Phytologist, Volume 251, Issue 6, Page 3096-3110, September 2026.
Proposed autotrophy to mycoheterotrophy continuum among arbuscular mycorrhizal plants. Summary The vast majority of land plants transfer part of the organic carbon they produce by photosynthesis to arbuscular mycorrhizal (AM) fungi inside their root cells; the fungi in turn help plants to take up nutrients and water from the soil.

Diversity of metaxylem vessel elements in three Syagrus palms (Arecaceae) of different habits Diversidade dos elementos de vaso do metaxilema em três espécies de Syagrus (Arecaceae) de diferentes hábitos

open access: yesActa Botânica Brasílica, 2011
Vessel elements in Monocotyledons present morphological differences according to the organ where they occur. Usually such diff erences have been explained from an evolutionary perspective, with few data on how the vessel elements could be infl uenced by ...

Away from violence: A latent transition analysis on support for violent and non‐violent radicalization among adolescents

open access: yesJournal of Child Psychology and Psychiatry, Volume 67, Issue 8, Page 1335-1347, August 2026.
Background Support for violent and non‐violent radicalization co‐exists in some, but not all, adolescents. Yet, little is known about how adolescents transition towards or away from violent and/or non‐violent radicalization over time. Within a socio‐ecological framework, this study investigates how Canadian adolescents move from profiles that support ...

Relationships between grain yield and accumulation of biomass, nitrogen and phosphorus in common bean cultivars Relações entre o rendimento de grãos e a acumulação de biomassa, nitrogênio e fósforo em cultivares de feijoeiro

open access: yesRevista Brasileira de Ciência do Solo, 2008
Shoot biomass is considered a relevant component for crop yield, but relationships between biological productivity and grain yield in legume crops are usually difficult to establish. Two field experiments were carried out to investigate the relationships

Wild Seasons, Urban Stasis: Anthropogenic Food Subsidies Buffer Seasonal Dietary Shifts for Coyotes (Canis latrans) in a Wildland‐Urban Landscape South of Mexico City

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
Coyote populations are expanding into urban areas, and this study examines how their diet adapts along a gradient from conserved to human‐modified habitats. Mammals dominated the diet at both sites, and there was no significant difference in annual dietary diversity between the conserved and modified areas.
