In vitro propagation of woody semi-mangrove species is often constrained by explant contamination, browning and stage-specific morphogenic responses. The authors examined how explant developmental state, basal-medium strength and plant growth regulators affected in vitro establishment and regeneration responses in Heritiera littoralis.

Unfurling fronds of Struthiopteris spicant in Northern California. Many lineages of ferns went extinct in the Paleozoic, but as a whole ferns have persisted for nearly 400 million years, and extant ferns have expanded into nearly all terrestrial ecosystems. Does competitive displacement really explain their Paleozoic evolutionary patterns? (Credit: Jacob Suissa.)

A figure summariing leaf heat tolerance, represented by T 50 (the temperature at which the maximum quantum efficiency of photosystem II is reduced by 50%), for five species of oak tree native to Los Angeles County, California, USA that received either regular watering (plain bars) or reduced watering (diagonal bars).
