Biodiversity in marine invertebrate responses to acute warming revealed by a comparative multi-omics approach.

Understanding species' responses to environmental change underpins our abilities to make predictions on future biodiversity under any range of scenarios. In spite of the huge biodiversity in most ecosystems, a model species approach is often taken in environmental studies. To date, we still do not know how many species we need to study to input into models and inform on ecosystem-level responses to change.

Constituents of Bulbs of three Species of the Hyacinthaceae (Hyacinthoideae): Eucomis vandermerwei, E. zambesiaca and Resnova humifusa.

Phytochemical analyses of the bulbs of Eucomis vandermerwei and E. zambesiaca yielded homoisoflavonoids and triterpenoid derivatives. A new (17S*23S*)-epoxy-3β,15β,29-trihydroxy-27-norlanost-8-en-24-one) was isolated from E.
