Macroevolutionary processes in turtles (Testudines): a view from biomic specialization and historical climatic changes

open access: yesFrontiers in Ecology and Evolution
The resource-use hypothesis proposed by Elisabeth S. Vrba suggests that lineages display varying tendencies toward generalism or specialization in biome occupancy, with a tendency towards the accumulation of specialists due to their higher rate of ...

Climate‐Induced Severe Water Scarcity Events as Harbingers of Global Wheat Price

open access: yesEarth's Future, Volume 14, Issue 8, August 2026.
Abstract This study connects the dots between global extent of severe water scarcity (SWS) events and spikes in food price. The authors start with three staple crops (rice, wheat, and maize) using a empirical but crop specific characterization of severe water scarcity occurrence, which is defined based on the area of land cultivated with each studied ...

A new instrument for stable isotope measurements of 13C and 18O in CO2 – instrument performance and ecological application of the Delta Ray IRIS analyzer [PDF]

open access: yesAtmospheric Measurement Techniques, 2017
We used the recently developed commercially available Delta Ray isotope ratio infrared spectrometer (IRIS) to continuously measure the CO2 concentration c and its isotopic composition δ13C and δ18O in a managed beech forest in central Germany.

Latitudinal Gradients in Position and Climatology of Upper Tree Limits Across Europe

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim The upper tree limit (UTL) marks the upper boundary of the realized niche of trees. It is commonly located below the treeline, which represents the cold boundary of the fundamental niche of trees. We hypothesized that the elevational offset between the UTL and the treeline is partly systematic and can be predicted using topographic and ...
