Testing key tenets of pyro-ecophysiology: Indicators of drought response in relation to shoot flammability. [PDF]

open access: yesAm J Bot
Abstract Premise Relationships between flammability and drought tolerance influence vegetation dynamics during fires. A goal of the emerging subdiscipline of pyro‐ecophysiology is to identify ecophysiological traits that determine live fuel flammability, but empirical studies of these relationships are rare.

Neontological and paleontological congruence in the evolution of Podocarpaceae (coniferales) reproductive morphology

open access: yesFrontiers in Ecology and Evolution, 2022
IntroductionPodocarpaceae are a diverse, primarily tropical conifer family that commonly produce large leaves and highly reduced, fleshy seed cones bearing large seeds.

Phylogeny and divergence times of gymnosperms inferred from single-copy nuclear genes. [PDF]

open access: yesPLoS ONE, 2014
Phylogenetic reconstruction is fundamental to study evolutionary biology and historical biogeography. However, there was not a molecular phylogeny of gymnosperms represented by extensive sampling at the genus level, and most published phylogenies of this

Diversity-Elevation Relationships of Vascular Plants in Austral Temperate Ecosystems Are Strata Dependent. [PDF]

open access: yesEcol Evol
We investigated diversity patterns of vascular plants of overstorey and understorey vegetation separately per stratum and the influence of anthropogenic disturbances along two elevational transects with contrasting slope aspects in a temperate rainforest and alpine scrub in southern Chile.

Paleovegetational Reconstruction and Implications on Formation of Oil Shale and Coal in the Lower Cretaceous Laoheishan Basin (NE China): Evidence from Palynology and Terpenoid Biomarkers

open access: yesEnergies, 2021
In some cases, the oil shale deposited in shallow lakes may be genetically associated with the coal-bearing successions. Although paleovegetation is an important controlling factor for the formation of oil shale- and coal-bearing successions, few studies

Evolution and relationships of the conifer seed cone telemachus: Evidence from the triassic of antarctica [PDF]

open access: yes, 2010
The seed cone Telemachus is known from several Triassic localities in Gondwana. New specimens from two localities in Antarctica provide additional information about the type species, Telemachus elongatus, based on details of morphology and anatomy ...

Conifer-angiosperm interactions: Physiological ecology and life history. [PDF]

open access: yes, 2011
Worldwide, conifers are most successful on sites subject to chronic stresses that limit productivity (low temperatures, nutrient poverty, poor drainage).

The complete chloroplast genome sequence of Podocarpus neriifolius (Podocarpaceae)

open access: yesMitochondrial DNA. Part B. Resources, 2020
The complete chloroplast (cp) genome sequence of Podocarpus neriifolius D. Don was determined by BGISEQ-500 platform sequencing in this study. The entire cp genome was determined to be 133,878 bp in length.

Environmental and climatic proxies for the Cañadón Asfalto and Neuquén basins (Patagonia, Argentina): review of middle to upper jurassic continental and near coastal sequences [PDF]

open access: yes, 2015
In this review, we include several proxies (sedimentology, palynology, invertebrates) from the Cañadón Asfalto and Neuquén basins, to infer the environments and regional climatic context during the Middle to Late Jurassic of Patagonia.
