Sensitivity of the grassland-forest ecotone in East African open woodland savannah to historical rainfall variation [PDF]

, 2014
. Fossil pollen records provide key insight into the sensitivity of terrestrial ecosystems to climate change at longer time scales. However, tracing vegetation response to relatively modest historical climate fluctuations is often complicated by the ...

Assessing the viability of genebanked seeds from rare, wild plants native to the United States using the D.E.A.D. paradigm

Applications in Plant Sciences, EarlyView.
Abstract Premise Genebanks must maintain viable seeds for decades. Seeds that germinate are clearly alive, but some seeds, often from wild populations, do not germinate because they are dormant, empty, aged, or damaged (D.E.A.D.). This work evaluates the effects of D.E.A.D.

Charred conifer remains from the Late Oligocene – Early Miocene of Northern Hesse (Germany)

Acta Palaeobotanica, 2018
Fire is an important constituent of many modern and fossil ecosystems. During the last decades a large number of studies have dealt with fires in pre-Cenozoic ecosystems. Evidence for the occurrence of Palaeogene and Neogene wildfires (e.g.

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
