Sphaerochara canadensis (Charophyceae): A circumpolar species with a high temperature optimum. [PDF]

J Phycol
Abstract Sphaerochara canadensis, an aquatic macrophyte belonging to the Characeae, is described as a species with a circumpolar distribution and occurs in the polar (to boreal) zonobiomes, suggesting that it is cold‐stenothermic. A recent report of an occurrence in Lake Wolfgangsee, Austria, contradicted this assumption, prompting this study to ...

Potassium extrusion by plant cells: evolution from an emergency valve to a driver of long-distance transport. [PDF]

New Phytol
Summary The ability to accumulate nutrients is a hallmark for living creatures and plants evolved highly effective nutrient transport systems, especially for the uptake of potassium (K+). However, plants also developed mechanisms that enable the rapid extrusion of K+ in combination with anions.

Optimized Laboratory Maintenance and Functional Testing of Chara braunii. [PDF]

Curr Protoc
Abstract Chara braunii is an emerging model species for studying plant evolution and development. Various members of the Chara genus have been used for pioneering studies of electrophysiology, cytoplasmic streaming, and cell biology. However, many studies have been limited by challenges, such as overgrowth with epiphytes or non‐continuous growth ...

A Comparative Analysis of Receptor-Like Kinases in Chlorophyta Reveals the Presence of Putative Cell Wall Integrity Sensors. [PDF]

Physiol Plant
ABSTRACT Receptor‐like kinases (RLKs) detect external and internal signals, triggering responses essential for growth and adaptation. Among internal cues, cell wall integrity (CWI) sensing plays a key role, as changes in cell wall structure activate responses critical for development and defense.

Habitat Diversity Sustains Ecosystem Functioning in Plateau Arid-Region Wetlands. [PDF]

Ecol Evol
Habitat diversity underpins both biodiversity and functional biogeochemical processes in plateau arid‐region wetlands, thereby stabilizing ecosystem functioning. These functionally complementary habitats collectively drive critical ecosystem processes.

High levels of species' extirpation in an urban environment-A case study from Berlin, Germany, covering 1700-2023. [PDF]

Ecol Evol
Our study compiled and analysed spatio‐temporal species' extirpation on a broad taxonomic coverage at the city scale. We revealed high number of extirpations, which are in the twenty‐firstcentury already comparable with previous centuries, and showed that cities might be suitable systems for studying species' extirpation processes due to their small ...
