Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

Application of Principal Component Analysis and Probabilistic Neural Networks in Ferralsols Recovery Evaluation Through Planting of Mabea Fistulifera and Eucalyptus Urograndis

Land Degradation &Development, EarlyView.
ABSTRACT This study presents an innovative assessment model for analyzing the evolution of degraded soils subjected to different reclamation strategies. The proposal combines statistical and artificial intelligence tools to jointly integrate multiple physical and chemical soil properties, allowing for a more synthetic view of the processes.

Effect of population reinforcement method, site, and plant characteristics on early establishment of the rare endemic plant species Minuartia smejkalii

Nordic Journal of Botany, EarlyView.
Many habitat‐specialist plant species have been endangered by fragmentation or destruction of their habitats. Minuartia smejkalii is a serpentinophyte endemic to the Czech Republic. It is highly threatened by recent habitat destruction and fragmentation, calling for effective conservation measures.

Variation in pollen limitation among reproductive modules points to likely resource reallocation in the alpine plant Veratrum grandiflorum

Nordic Journal of Botany, EarlyView.
Pollen limitation, a decrease in seed production due to insufficient pollen receipt, may influence plant demography and the evolution of sexual systems. Its empirical estimation of pollen supplementation of some of the flowers on an individual is well known to be prone to overestimation due to potential resource reallocation among the individual's ...

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

The reduction in genetic quality of seeds resulting from self-pollination acts as a pivotal factor limiting the regeneration of the endangered plant Tetracentron sinense Oliv

Global Ecology and Conservation
Tetracentron sinense Oliv., an endangered relict species from the Eocene, primarily relies on self-pollination in nature. However, the impacts of self-pollination on seed quality, seedling viability, and population renewal remain unclear.
