Vegetation changes over the last centuries in the Lower Lake Constance region reconstructed from sediment‐core environmental DNA

open access: yesEnvironmental DNA, Volume 4, Issue 4, Page 830-845, July 2022., 2022
The reconstruction of the historical shoreline vegetation across multiple basins of Lower Lake Constance using sedDNA, reveals the irreversible trajectory of the plant communities in relation to extensive anthropogenic pressures in the region. Abstract Many European lake ecosystems, including their respective catchment areas, underwent anthropogenic ...

The Angiosperm Terrestrial Revolution and the origins of modern biodiversity

open access: yesNew Phytologist, Volume 233, Issue 5, Page 2017-2035, March 2022., 2022
Summary Biodiversity today has the unusual property that 85% of plant and animal species live on land rather than in the sea, and half of these live in tropical rainforests. An explosive boost to terrestrial diversity occurred from c. 100–50 million years ago, the Late Cretaceous and early Palaeogene. During this interval, the Earth‐life system on land

Examining the utility of DNA barcodes for the identification of tallgrass prairie flora

open access: yesApplications in Plant Sciences, Volume 9, Issue 1, January 2021., 2021
Premise The tallgrass prairies of North America are one of the most threatened ecosystems in the world, making efficient species identification essential for understanding and managing diversity. Here, we assess DNA barcoding with high‐throughput sequencing as a method for rapid plant species identification.

Spatial distribution patterns and formation of global spermatophytes. [PDF]

open access: yesJ Integr Plant Biol
The global Spermatophyte Spatial Evolutionary System defines 18 distribution types and six supertypes across three floristic elements, primarily formed between the Eocene and Miocene and shaped by climate, long‐distance dispersal, and tectonic movement, revealing that similar distribution patterns of spermatophytes were driven by comparable formation ...

Extroparvum occidentale gen. et sp. nov. and the Cretaceous diversification of Lauraceae

open access: yesAmerican Journal of Botany, Volume 113, Issue 7, July 2026.
Abstract Premise The fossil record of Lauraceae extends back to the Early Cretaceous and comprises numerous flowers. However, phylogenetic relationships of many of these fossil flowers remain unresolved. To better understand the early evolutionary history of Lauraceae, we conducted phylogenetic analyses of living and extinct members of the family and ...

The transformation of macrophyte‐derived organic matter to methane relates to plant water and nutrient contents

open access: yesLimnology and Oceanography, Volume 64, Issue 4, Page 1737-1749, July 2019., 2019
Abstract Macrophyte detritus is one of the main sources of organic carbon (OC) in inland waters, and it is potentially available for methane (CH4) production in anoxic bottom waters and sediments. However, the transformation of macrophyte‐derived OC into CH4 has not been studied systematically, thus its extent and relationship with macrophyte ...

Plastid phylogenomic analysis of green plants: A billion years of evolutionary history

open access: yesAmerican Journal of Botany, Volume 105, Issue 3, Page 291-301, March 2018., 2018
Premise of the Study For the past one billion years, green plants (Viridiplantae) have dominated global ecosystems, yet many key branches in their evolutionary history remain poorly resolved. Using the largest analysis of Viridiplantae based on plastid genome sequences to date, we examined the phylogeny and implications for morphological evolution at ...
