Can alpine species take the heat?: Impacts of increased temperatures on early life stages

Climate change threatens plant biodiversity worldwide. Alpine plant species are particularly vulnerable to climate change, as temperature fluctuations are projected to be most severe in high elevation areas. Even small shifts in climate can have major consequences on phenology, reproduction, fitness, and community composition. Early life stages (seed germination and seedling survival) are arguably the […]

Seed viability Hawai‘i’s foundational-ʻōhi‘ trees linked environmental variables

Nina Rønsted, National Tropical Botanical Garden Climate can play a critical role in plant physiological processes at all life stages, but investigations into climate effects often focus on only adult life stages. However, climate can influence seed development and germination, which can in turn strongly affect community dynamics. Native Hawaiian Metrosideros spp. (Myrtaceae; ʻōhi‘a,; 13 […]

Christina Carrero, The Morton Arboretum, Emily Coffey, Atlanta Botanical Garden, Patrick Griffith, Montgomery Botanical Center A 2019 study by Griffith, et al. showed that gardens must collaborate to conserve genetic diversity, especially for exceptional species whose seeds cannot be properly seed banked. This process of capturing the genetic diversity of exceptional species in ex situ […]
