Late Jurassic Carbon Isotope Excursion (Middle Oxfordian Event) Paces With Astronomical Forcing in the Northwestern Tethys

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Marine carbonate carbon isotopes (δ13C), over orbital to multi‐million‐year timescales, provide critical insight into the carbon cycle connecting Earth's atmosphere, lithosphere, hydrosphere and biosphere. However, the influence of astronomical forcing on deep time carbon cycle dynamics remains poorly constrained.

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

open access: yesGeosciences
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 ...

Microbial endolithic community at Meteor Crater

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 6, Page 955-962, June 2026.
Abstract Postimpact recovery and evolution in response to climate changes produced a modern ecosystem at Meteor Crater dominated by a grassland and woodland of piñon and juniper, which has been used to evaluate floral and megafaunal consequences of impact cratering during the Phanerozoic Eon of complex life.

Development of Holocene lacustrine microbialites on the Iberian Peninsula: Insights into environmental and depositional controls using X‐ray CT and petrography

open access: yesSedimentology, Volume 73, Issue 4, Page 1148-1184, June 2026.
ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

Changes in Chara hispida L. morphology in response to phosphate aluminium coagulant application

open access: yesLimnological Review, 2018
Progressing eutrophication of waterbodies requires measures to be undertaken that aim at halting or reversing negative changes in the environment. Chemical restoration is one of the most common methods used for lake treatment, where iron or aluminium ...

Aquatic and Littoral Successions in Various Post‐Mining Sites—Patterns and Possible Use in Ecological Restoration

open access: yesLand Degradation &Development, Volume 37, Issue 9, Page 3842-3852, 30 May 2026.
ABSTRACT Vegetation succession in aquatic and littoral habitats has received much less attention than terrestrial habitats have. We sampled differently aged successional stages at five different types of post‐mining sites, that is, sandpits, stone quarries, clay quarries, brown coal spoil heaps and black coal subsidences, across the Czech Republic ...

Spatial relationships between macrophyte assemblages, water and sediment features in deep lakes

open access: yesFrontiers in Environmental Science
Despite the global ecological and societal importance of deep lakes and their associated biota and ecosystem services, the relationships between water and sediment features and the spatial patterns of macrophyte assemblages remain poorly understood in ...

Revision of the Eduardo Reyes Prósper’s herbarium and typification of three species of charophytes (Charophyceae : Characeae) present within it

open access: yesAnales del Jardín Botánico de Madrid, 2019
A study of the charophytes collected by Eduardo Reyes Prósper in the period 1904–1906 and kept in the herbarium of the Royal Botanical Garden of Madrid (MA-ALGAE) is carried out.

Origin and evolution of the nuclear auxin response system

open access: yeseLife, 2018
The small signaling molecule auxin controls numerous developmental processes in land plants, acting mostly by regulating gene expression. Auxin response proteins are represented by large families of diverse functions, but neither their origin nor their ...
