The Early Cretaceous mesofossil flora of Catefica, Portugal: angiosperms

open access: yes, 2022
Angiosperm mesofossils are described from the Lower Cretaceous Almargem Formation exposed near the village of Catefica, Portugal, and are thought to be of Aptian-early Albian age. The mesofossil assemblage from Catefica is diverse and, in addition to the

Looking backward to move forward: Enhancing metadata in scientific collections through interdisciplinary collaboration

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Early modern herbaria house important and useful data on historic environments. However, their contents are often inhospitable to scientific use. Despite this challenge, once their contents have been deciphered, such specimens present novel research opportunities.

Quantitative chemobiology: a guide into the understanding of plant bioactivity

open access: yesJournal of the Brazilian Chemical Society, 2002
Nothing is more important for human survival today, than understanding nature's mechanisms via a chemo-biological language. This multidisciplinary approach is a complex operation, because it involves integration of several levels of organization, such as

Gene turnover in the common ancestor of all C4 grasses

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Understanding how plants evolve more efficient photosynthesis is important in a warming world where improving crop productivity and resilience is a global priority. By generating the first reference genomes for an early‐diverging group of grasses called the Aristidoideae, we were able to reconstruct the genetic makeup of the last common ancestor of all

The most threatened plants receive the least scientific attention

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Plants sustain all life, providing the energetic and structural basis of ecosystems, but they face a growing risk of extinction. Reversing this decline requires an understanding of how scientific knowledge is distributed among species, and identification of the biases and gaps that hinder effective responses to the threats they face. However, we reveal

The earliest occurrence of Angiosperms in southern Africa

open access: yes, 2004
Three outcrop localities and 28 onshore and offshore cores and wells were sampled from the east coast, Zululand and Durban Basins, the south coast onshore Algoa and the offshore Outeniqua Basins, and the west coast Orange Basin.

Plant functional groups and root traits are linked to exudation rates of mature temperate trees

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Root exudation affects soil biogeochemistry profoundly, yet it is rarely quantified in mature, field‐grown trees and its controls are poorly understood. We measured rates of carbon (C) exudation in 11 tree species that exhibit divergent root traits, including ...

Leaf energy balance modelling as a tool to infer habitat preference in the early angiosperms [PDF]

open access: yes, 2015
Despite more than a century of research, some key aspects of habitat preference and ecology of the earliest angiosperms remain poorly constrained. Proposed growth ecology has varied from opportunistic weedy species growing in full sun to slow-growing ...

Wood anatomical trait correlations with hydraulic efficiency and safety in an aseasonal wet tropical forest

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Xylem anatomy underpins the capacity of trees to transport water while avoiding hydraulic failure, shaping species performance and resilience to climate change. However, the specific ways anatomical traits underpin hydraulic trade‐offs in tropical forests remain debated.
