This study also indicated that deforestation and poplar industry along habitat loss, over grazing, unawareness, annual fire practices and exploitation of medicinal plants were the major threats to the angiosperms
Furthermore, constantly increasing knowledge about the phylogenetic relationships among vascular plants, especially angiosperms
(Smith et al.
The predominant ray type in Brassicales is Heterogeneous Type II (which is also the most common type in angiosperm
The rapid diversification of angiosperms
in the Cretaceous was a radiation nonpareil--in just 40 million years the group came to dominate global floras in both diversity and abundance (Wolfe, 1997; Crane and Lidgard, 1990).
Pit membranes of Ephedra resemble gymnosperms more than angiosperms
Response of the pine engraver, Ips pini (Say) (Coleoptera: Scolytidae), to conophthorin and other angiosperm
bark volatiles in the avoidance of non-hosts.
Furthermore, among the habitats of Tehuantepec, the tropical dry forests harbor the largest diversity including several taxa of endemic angiosperm
(Acosta et al.
Fossil evidence for Cretaceous escalation in angiosperm
leaf vein evolution.
Using Fossils to Break Long Branches in Molecular Dating: A Comparison of Relaxed Clocks Applied to the Origin of Angiosperms
Among plants, particularly angiosperms
, the selection of a standard barcode is more difficult mainly due to the evolutionary trends of each of the three plant genomes.
A revised system of classification of the angiosperms
Seed ferns from the late Paleozoic and Mesozoic: any angiosperm
ancestors lurking there?
A further assessment of available-N status was provided by a comparison with other New Zealand forest sites on Orthic Pumice soils that supported mixed angiosperm
and conifer species.
endozoochory: were pterosaurs cretaceous seed dispersers?
Even in Aardsmas virtual history, there would be evidence of an origin of angiosperms
that would include an observable first appearance of angiosperm
plants and their pollen and evidence of the proliferation of flowering plant groups over some period of virtual history.
