We review recent advances on glossopterid reproductive biology and their implications for
seed plant phylogeny and the ecology of this widespread Permian Gondwanan group …

Although Siberian Trap volcanism is considered a primary driver of the largest extinction in
Earth history, the end-Permian crisis, the relationship between these events remains …

A current synthesis of data from modern and fossil plants paints a new picture of sexual
fluids, including nectar, as a foundational component of gymnosperm reproductive evolution …

Disturbances in terrestrial vegetation across the end-Triassic mass-extinction (ETME) and
earliest Jurassic (∼ 201.5–201.3 Ma) have previously been linked to carbon cycle …

Pollen malformations have been proposed as a paleoenvironmental stress proxy. However,
the frequency and variability of pollen malformations under near-optimal conditions and …

The male gametophytes of gymnosperms are characterized by the diversities in pollen
morphology, cellular composition and pattern of cell division, pollen tube morphology, sperm …

Corystosperms, a key extinct group of Late Permian to Early Cretaceous plants, are
important for understanding seed plant phylogeny, including the evolution of the angiosperm …

In this multi-proxy palaeo study, the response of primary producers and consumers to
anthropogenic disturbances in a large shallow lake was investigated. Overall, eutrophication …

Studies of cycad pollination globally have revealed obligate pollination mutualisms with
insects, typically host-specific beetles. Some cycads in the genus Cycas have floating seeds …

Three-dimensional electron microscopy (3D-EM) has attracted considerable attention
because of its ability to provide detailed information with respect to developmental analysis …
