The periderm acts as armor protecting the plant's inner tissues from biotic and abiotic stress.
It forms during the radial thickening of plant organs such as stems and roots and replaces …

During the mid-Palaeozoic, vascular land plants (ie, tracheophytes) underwent a great
radiation that triggered the development of the land biosphere–the so-called Silurian …

Global reconstructions, inclusive of environments and ecosystems, and biodiversity counts
for the Devonian Period are often done so at the expense of high latitude regions given a …

The first land ecosystems were composed of organisms considered simple in nature, yet the
morphological diversity of their flora was extraordinary. The biological significance of this …

For the first time, ophiuroids have been found in South African strata predating the

Yarravia oblonga is emended here and adds to our knowledge of floral diversity during the
late Silurian and Early Devonian of central Victoria, Australia. Examination of specimens and …

Abstract The Silurian–Devonian transition played a crucial role in the development of early
terrestrial ecosystems due to the rapid diversification of early vascular plants. However …

Abstract The Silurian–Devonian plant radiation was an event triggered by the progressive
colonization of subaerial habitats. Nevertheless, it is still unclear whether this radiation was …
