Pollinator diversity and host specificity in threatened Encephalartos cycads and their implications for co‐extinction and species recovery

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The highly threatened African cycad genus Encephalartos faces severe threats such as habitat loss and poaching. In addition, the lack of sexual recruitment due to the absence of pollinators (pollinator collapse) has emerged as another major threat.

‘I like to dance with the flowers!’: Exploring the possibilities for biodiverse futures in an urban forest school

Children &Society, EarlyView.
Abstract This article explores the ways in which ‘forest school’, an educational approach where children engage in creative and play based activities in a ‘natural’ environment, can contribute towards Sustainable Development Goal 15 (SDG 15) by promoting sustainable use of terrestrial ecosystems and by helping address biodiversity loss. Drawing on data

Differences in characteristics between naturalized threatened plants and other threatened plants

Conservation Biology, EarlyView.
Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.
