Species Richness Gradients Vary Across Phylogenetic Scales
Global Ecology and Biogeography, Volume 34, Issue 12, December 2025.ABSTRACT Aim To determine how species richness gradients—commonly considered universal—vary across the phylogenetic hierarchy of birds and mammals, and to uncover how clade age and size predetermine the gradients. Location Global. Time Period Last 120 million years. Taxa Studied Birds and mammals (~15,000 species).

Urbanisation Is Related to the Prevalence of Threatened Species on Islands Across the Globe
Global Ecology and Biogeography, Volume 34, Issue 12, December 2025.ABSTRACT Aim To assess how environmental characteristics and human impacts contribute to the global prevalence of threatened bird species on islands (the ratio of threatened to non‐threatened species per island), and to identify which types of land use are most strongly associated with extinction risk on islands. Location Global.

Wie kostbar ist Strandsand? [PDF]
, 2009 Auf der Erde gibt es viele Strände. Je breiter ein Strand und je feiner sein Sand, desto schöner finden ihn die Menschen. Doch woher kommt der Sand und wem gehört er? Schützt uns der Strand vor Sturmfluten? Wie kostbar Strandsand ist, erklärt Professorin

Inferring Antarctic Ice Dynamics and Boundary Conditions From the Ice Sheet's Basal Unit
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract In their study, Young et al. (2025, https://doi.org/10.1029/2025GL115729) employ airborne radio‐echo sounding data to map the basal unit over the East Antarctic Ice Sheet over a large area between Dome A and South Pole. The authors use the results to infer conclusions about ice‐dynamic behavior of the ice sheet, geology, temporal development ...

Opportunistic Constant Target Matching—A New Method for Satellite Intercalibration
Earth and Space Science, 2020 Opportunistic constant target matching is a new method for satellite intercalibration. It solves a long‐standing issue with the traditional simultaneous nadir overpass (SNO) method, namely, that it typically provides only data points with cold brightness

On The Existence of Highly Condensed Sulfatotungstates and Sulfatomolybdates
ChemistryEurope, Volume 3, Issue 6, November 11, 2025.GA: The very first sulfatotungstates and sulfatomolybdates with two‐ and three‐dimensional condensed anions show a remarkable thermal stability and may open the door to a new class of condensed antenna phosphors with reduced vibrational quenching. We also focus on their optical properties and their phase‐pure synthesis at comparably mild temperatures ...

Sedimentary and tectonic evolution of ancient Lake Ohrid (Macedonia/Albania) [PDF]
, 2009 Lake Ohrid (Macedonia / Albania) is probably the oldest lake in Europe (2-5 Ma), and is considered an important sedimentary archive to study the evolution of a graben system over several million years.

The Depositional Record, Volume 11, Issue 5, Page 1376-1398, November 2025.A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes
