Research at the UNESCO World Heritage Site Messel Pit Fossil Site (Germany) reveals that Early to Middle Eocene continental hydroclimate in Central Europe was more variable than previously assumed, with abrupt temperature shifts coinciding with potential changes in moisture conditions. Using highly-resolved biomarker-based paleoclimate data from the site's finely laminated lake sediments, scientists reconstructed mean annual air temperatures ranging from 14 to 22°C over ~640,000 years (~48.0-47.4 Ma). Short-term temperature excursions of 4-5°C were identified, alongside significant variations in hydrogen and carbon isotope values of leaf waxes, suggesting dynamic hydroclimatic conditions. This study provides the first detailed quantification of long-term Eocene cooling in a terrestrial Central European archive, offering critical insights for climate modeling and understanding past climate variability.

Between 1965 and 2015, Surtsey witnessed significant vascular plant colonization, with 74 species identified. Initial rapid colonization (1965–1979) stagnated until the establishment of a dense seagull colony in 1986, which drastically accelerated plant growth, peaking between 1992 and 1995. Six vegetation types emerged, ranging from sparse pioneer communities to lush, nutrient-rich grasslands influenced by seabird activity. Species richness increased from an average of 4.8 to 10.4 per hectare over the study period. Pioneering species like <em>Honckenya peploides</em>, <em>Poa annua</em>, and <em>Silene uniflora</em> led colonization, thriving on sandy lava and barren surfaces. Despite seabird impacts, most of Surtsey remains sparsely vegetated, offering insights into ecological succession in extreme environments.

Two new species of yellow-green algae, <em>Vaucheria coronata</em> and <em>V. velutina</em>, have been documented for the first time in the Arkhangelsk Region (White Sea), with <em>V. coronata</em> marking a second Russian record and <em>V. velutina</em> representing its debut in the White Sea. The discovery expands the known biodiversity of the Solovetsky Islands by identifying unique morphological traits and habitat preferences of these algae. The research combines field observations with morphological analysis to characterize their growth localities and distribution patterns, contributing new data to regional algal taxonomy.

Research on Mt. Teide, the highest volcano in the Atlantic, reveals significant upward shifts in the elevational ranges of 23 plant species since Humboldt's observations in 1799 and 1815, with an average shift of 36.4 meters per decade (1799/1815–2021). This study leverages historic data from Humboldt's <em>Tableau Physique des Iles Canaries</em> alongside modern surveys to assess vegetation changes, likely influenced by climate warming and reduced herbivory post-goat eradication. The findings highlight the magnitude of biotic change over two centuries, providing one of the earliest records for this UNESCO-listed site.

A study of Nanda Devi and Valley of Flowers National Parks reveals significant differences in vegetation dynamics and soil nutrient availability along an altitudinal gradient. The research found that species richness and diversity decrease with increasing altitude, while the regeneration status of tree species varies between sites, with 40% showing good regeneration at one site compared to only 22% at another. Betula utilis was the dominant tree species in both sites, followed by Pinus wallichiana and Cedrus deodara. The study also highlighted differences in vegetation structure and soil properties based on aspect (southern vs. northern). To effectively monitor these changes, the authors recommend establishing permanent vegetation plots with meteorological stations for long-term monitoring of forest dynamics in response to climate change and anthropogenic pressures.
