Biological edge effects are often assessed in high quality focal habitats that are negatively influenced by human-modified low quality matrix habitats. A deeper understanding of the possibilities for positive edge effects in matrix habitats bordering focal habitats (e.g. spillover effects) is, however, essential for enhancing landscape-level resilience to human alterations. We surveyed epixylic...

Aim There is increasing recognition that plant–soil feedbacks drive species co-existence; therefore the below-ground compartment should be better considered in ecological restoration. Addition of carbon a restoration measure relies on indirect relationships by immobilizing soil nitrogen microbial biomass to manipulate competitive hierarchies between plant species. The aim present work was evalu...

We propose an equation to evaluate the efficiency of a classification as function effort required and population size data collectors. The formula postulates “classification coefficient”, which relates not only complexity object be classified, but also availability representativeness. When applied phytocoenoses, suggests that system based on vascular plants offers best compromise between sampli...

Phytochromes are plant photoreceptors important for development and adaptation to the environment. Phytochrome A (PHYA) is essential for the far-red (FR) high-irradiance responses (HIRs), which are of particular ecological relevance as they enable plants to establish under shade conditions. PHYA and HIRs have been considered unique to seed plants because the divergence of seed plants and crypto...

Herbivory can aff ect plant community composition and diversity by removing biomass and reducing light competition. Herbivory may particularly benefi t low growing species such as bryophytes, which are frequently limited by light competition. Gastropods are important herbivores of seed plants and cryptogams, furthermore, they can disperse propagules such as seeds and spores via endozoochory. Ho...

Questions Observations in permanent forest vegetation plots Norway and elsewhere indicate that complex changes have taken place over the period 1988–2020. These observations are summarised “climate-induced understorey change (CIUC)” hypothesis, i.e. of old-growth boreal forests undergoes significant long-term these consistent with ongoing climate as an important driver. Seven testable predictio...

Adventitious rooting is essential for the survival of numerous species from vascular cryptogams to monocots, and is required for successful micropropagation. The tissues involved in AR initiation may differ in planta and in in vitro systems. For example, in Arabidopsis thaliana, ARs originate from the hypocotyl pericycle in planta and the stem endodermis in in vitro cultured thin cell layers. T...

Georeferenced species data have a wide range of applications and are increasingly used for e.g. distribution modelling and climate change studies. As an integrated part of an on-going survey programme for vegetation mapping, plant species have been recorded. The data described in this paper contains 18.521 registrations of plants from 1190 different circular plots throughout Norway. All species...
