Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, Volume 600, Issue 10, Page 1491-1518, May 2026.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Preservation and palaeobiogeography of dinosaur eggs from the Dadaepo Formation (Upper Cretaceous: Cenomanian), Korea

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Dinosaur eggs were recovered from the Dadaepo Basin in Busan (south‐east Korea), which is early Late Cretaceous in age and is close to Japan, but the eggs have not been studied. Among East Asian egg‐bearing basins, the Dadaepo Basin is characterized by exceptionally high thermal maturity (c.

Charophytes (Characeae, Charophyceae) of Bosnia and Herzegovina—35 Years After the Last Systematic Overview

Phycology
The overview of charophytes in Bosnia and Herzegovina has been updated after 35 years through a revision of existing specimens in the BEOU Charophyte Collection, verification and listing of known vouchers in other herbarium collections, and a detailed ...

Estimating responses of marine benthic communities to reduced nutrient loading using process‐based and statistical modelling

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.
Our framework links policy targets (achieving good ecological status) and actions (nutrient emission reductions) to realized biodiversity benefits. The approach also supports the optimal placement of monitoring sites under different nutrient abatement scenarios.

Arabinogalactan Proteins and the Extracellular Matrix of Charophytes: A Sticky Business [PDF]

Frontiers in Plant Science, 2019
Charophytes represent the group of green algae whose ancestors invaded land and ultimately gave rise to land plants 450 million years ago. While Zygnematophyceae are believed to be the direct sister lineage to embryophytes, different members of this group (Penium, Spirogyra, Zygnema) and the advanced thallus forming Coleochaete as well as the sarcinoid

Diterpenoid Diversity across Land Plants

Helvetica Chimica Acta, Volume 109, Issue 4, April 2026.
Here we bridge the knowledge of diterpene chemical diversity, biosynthesis, and evolution from nonvascular mosses and liverworts to that known from vascular plants. ABSTRACT The diverse array of diterpenoid natural products stems from the ease of manipulating the promiscuity of diterpene cyclases.

The coming and going of a marl lake: multi-indicator palaeolimnology reveals abrupt ecological change and alternative views of reference conditions [PDF]

, 2015
Eutrophication is the most pressing threat to highly calcareous (marl) lakes in Europe. Despite their unique chemistry and biology, comprehensive studies into their unimpacted conditions and eutrophication responses are underrepresented in conservation ...

Generalized Mechanism Model for Ecosystem Hysteresis

Advanced Science, Volume 13, Issue 17, 23 March 2026.
A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...

What Do Fossil charophytes Whisper to Us? Palaeoecological and Palaeoenvironmental Reports from Pleistocene Continental Deposits of Umbria (Central Italy)

Geosciences
The Early Pleistocene continental deposits of the Tiberino Basin (Central Italy) host exceptionally preserved fossil charophyte assemblages that provide critical insights into palaeoenvironmental and palaeoclimatic dynamics during a key phase of the ...
