open access: yesPeople and Nature, EarlyView.
Abstract Efforts to conserve biodiversity in agricultural landscapes across Europe remain insufficient, as biodiversity further declines. This is sometimes ascribed to conservation policy failing to address the meanings and values that farmers attribute to the social and ecological contexts shaping their decisions influencing biodiversity.

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.

Prospective of indigenous African wild food plants in alleviation of the severe iron deficiency anaemia in Sub‐Saharan Africa

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Iron deficiency anaemia remains a major public health challenge in Sub‐Saharan Africa, where population growth, displacement and limited resources heighten nutritional insecurity. We compiled a list of indigenous African underutilized wild food plants and examined their potential for addressing micronutrient deficiencies.

Variation in Floral Nectar Traits of Four Chestnut (Castanea spp.) Cultivars: Implications for Pollinators and Apiculture

open access: yesAgriculture
Pollinator nutrition and honey production potential depend on nectar quantity, nectar availability across flowering phases, and sugar concentration. For chestnut (Castanea spp.), cultivar- and flowering phase-specific nectar data remain limited.
