Fossil data support a pre-Cretaceous origin of flowering plants
Flowering plants (angiosperms) are the most diverse of all land plants, becoming abundant in the Cretaceous and achieving dominance in the Cenozoic. However, the exact timing of their origin remains a controversial topic, with molecular clocks generally placing their origin much further back in time than the oldest unequivocal fossils....Silvestro, Daniele ; Bacon, Christine D. ; Ding, Wenna ; Zhang, Qiuyue ; Donoghue, Philip C.

A robust phylogenomic framework for the calamoid palms
Well-supported phylogenies are a prerequisite for the study of the evolution and diversity of life on earth. The subfamily Calamoideae accounts for more than one fifth of the palm family (Arecaceae), occurs in tropical rainforests across the world, and supports a billion-dollar industry in rattan products. It contains ca. 550...Kuhnhäuser, Benedikt G. ; Bellot, Sidonie ; Couvreur, Thomas L.P. ; Dransfield, John ; Henderson, Andrew …

Habitat specialisation controls ectomycorrhizal fungi above the treeline in the European Alps
Alpine habitats are one of the most vulnerable ecosystems to environmental change, however, little information is known about the drivers of plant–fungal interactions in these ecosystems and their resilience to climate change. We investigated the influence of the main drivers of ectomycorrhizal (EM) fungal communities along elevation and environmental gradients... -

Repeat-sequence turnover shifts fundamentally in species with large genomes.
Given the 2,400-fold range of genome sizes (0.06–148.9 Gbp (gigabase pair)) of seed plants (angiosperms and gymnosperms) with a broadly similar gene content (amounting to approximately 0.03 Gbp), the repeat-sequence content of the genome might be expected to increase with genome size, resulting in the largest genomes consisting almost entirely of repetitive...Novák, Petr ; Guignard, Maïté S. ; Neumann, Pavel ; Kelly, Laura J. ; Mlinarec, Jelena …

Identifying and mapping individual plants in a highly diverse high-elevation ecosystem using UAV imagery and deep learning
The identification and counting of plant individuals is essential for environmental monitoring. UAV based imagery offer ultra-fine spatial resolution and flexibility in data acquisition, and so provide a great opportunity to enhance current plant and in-situ field surveying. However, accurate mapping of individual plants from UAV imagery remains challenging, given...Zhang, Ce ; Atkinson, Peter M. ; George, Charles ; Wen, Zhaofei ; Diazgranados, Mauricio …

Rapid diversification rates in Amazonian Chrysobalanaceae inferred from plastid genome phylogenetics
We studied the evolutionary history of Chrysobalanaceae with phylogenetic analyses of complete plastid genomes from 156 species to assess the tempo of diversification in the Neotropics and help to unravel the causes of Amazonian plant diversification. These plastid genomes had a mean length of 162 204 base pairs, and the...Chave, Jerome ; Sothers, Cynthia ; Iribar, Amaia ; Suescun, Uxue ; Chase, Mark W …

A model-data fusion approach to analyse carbon dynamics in managed grasslands.
Grasslands are an important component of the global carbon (C) cycle, with a strong potential for C sequestration. However, an improved capacity to quantify grassland C stocks and monitor their variation in space and time, particularly in response to management, is needed in order to conserve and enhance grassland C...Myrgiotis, Vasileios ; Blei, Emanuel ; Clement, Rob ; Jones, Stephanie K. ; Keane, Ben …

Floristics of forests across low nutrient soils in Sulawesi, Indonesia.
The island of Sulawesi formed from the joining of proto‐islands roughly three million years ago. Regions of zoological endemism, corresponding to the proto‐islands, have been reported. Sulawesi's tree communities, however, remain poorly documented. In better‐studied tropical regions, soil types similar to those found in Sulawesi often have distinctive tree communities....
