Rubisco evolution in C4 eudicots: an analysis of Amaranthaceae sensu lato [PDF]

open access: yes, 2015
BACKGROUND Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) catalyses the key reaction in the photosynthetic assimilation of CO₂. In C₄ plants CO₂ is supplied to Rubisco by an auxiliary CO₂-concentrating pathway that helps to maximize the ...

Extreme environments in a world of new extremes

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
Abstract Extreme environments, whether defined by climate, soils, or disturbance, at landscape or micro‐scales, are prevalent across Earth's surface and have long served as crucibles for ecological and evolutionary insights. Many foundational theories were developed in deserts, cliffs, ultramafic soils, and other harsh systems.

Bulk tissue versus amino acid carbon stable isotopes to reveal the diet and basal resource use of an invasive rodent

open access: yesEcosphere, Volume 17, Issue 2, February 2026.
Abstract Stable isotope analysis (SIA) is widely used to reconstruct food webs, characterize trophic relationships, and estimate dietary composition. However, bulk tissue SIA (BSIA) can yield imprecise estimates when dietary sources are isotopically similar.

Age of innovation: Progress in systematic botany in the 20th century

open access: yesTAXON, Volume 75, Issue 1, February 2026.
Abstract Systematic botany can be regarded as the oldest of the botanical sciences, having originated with the ancient Greeks. Although much progress has been achieved in systematic botany over nearly two millennia, in the 20th century, many significant innovations took place in revealing processes of evolution, principles and methods of classification,
