Embryo excision in Compositae, with implications for combating biodiversity loss
Applications in Plant Sciences, Volume 12, Issue 5, September-October 2024.Abstract Premise Embryo excision is an effective, under‐described means of promoting germination in the sunflower family and may help to ensure the survival of endangered taxa or lineages with limited seed availability. Methods and Results We describe and illustrate a detailed method of embryo excision used successfully to stimulate germination in a ...

The specialised buzz pollination syndrome poses a partial barrier to plant invasions
Journal of Ecology, Volume 112, Issue 8, Page 1686-1700, August 2024.We found that plants that exhibit traits consistent with the buzz‐pollination syndrome are underrepresented as invasive species across the globe. Our result suggests that the specialist buzz‐pollination syndrome poses a partial barrier to plant invasions. Our review also highlighted six alternative insect behaviours that can enable invasive plants with

Journal of Ecology, Volume 112, Issue 7, Page 1533-1549, July 2024.Despite strong specialization to gypsum soils, past divergent selection related to climatic gradients has driven adaptive population differentiation in Lepidium subulatum. All populations showed high but similar plasticity to drought, indicating that selection did not act against plasticity in harsh environmental conditions.

Opportunities and challenges for strawberry cultivation in urban food production systems
PLANTS, PEOPLE, PLANET, Volume 6, Issue 3, Page 611-621, May 2024.Cultivation of strawberry plants in urban production systems, whether in green open‐air spaces or under some form of protected horticulture such as vertical farming, has demonstrated to be challenging to new farmers and businesses. Commercial strawberry producers have an advanced understanding of strawberry plant physiology, enabling them to grow the ...
