Forest floor vegetation in Sweden [PDF]

open access: yes, 2012
In boreal forests, dwarf-shrubs (Vaccinium spp.) often dominate the forest floor and are key-stone species in ecosystems due to their importance for nutrient cycling and as a major food source for herbivores. Forestry affects the vegetation both directly

A dynamic epigenetic perspective on above‐ and belowground phenotypic responses to drought: Insights from global DNA methylation in Erodium cicutarium

open access: yesPlant Biology, EarlyView.
Our factorial experimental design investigates the relationships between DNA methylation, plant development and individual fitness under stress in Erodium cicutarium. We found that epigenetic modifications associated to 5‐azacytidine seed treatment desynchronized plant growth and delayed flowering.

Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume

open access: yesPlant Biology, EarlyView.
Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Living in the Mycelial World

open access: yesTopics in Cognitive Science, EarlyView.
Abstract This manuscript documents a systematic ethnomycological analysis of ethnographic archives. Focusing on texts describing human–fungi interactions, I conduct a global, cross‐cultural review of mushroom use, covering 193 societies worldwide. The study reveals diverse mushroom‐related cultural practices, emphasizing the significance of fungi ...
