Mediterranean ecosystems face complex, multi‐trophic impacts from global‐change drivers, yet responses are often studied in isolation. Using the Doñana Protected Area as a case study, we illustrate how anthropogenic pressures on key species like cork oaks and rabbits, as well as increases in species like wild boar and invasive crayfish, lead to ...

The Evolution of Hutchinsonian Climatic Niche Hypervolumes in Gymnosperms
ABSTRACT Aim The niche is a fundamental concept in theoretical and experimental ecology and is used to describe a wide range of ecological processes from species' interactions with the environment to community assemblies. A common way to represent the niche is through a multidimensional geometry known as the Hutchinsonian niche hypervolume.

An eco‐evolutionary optimality model explains the acclimated temperature response of photosynthesis
Summary The optimal temperature of photosynthesis (Topt) generally increases with plant growth temperature. Changes in Topt are associated with changes in the maximum carboxylation capacity at 25°C (Vcmax25) and the maximum electron transport rate at 25°C (Jmax25). The ratio between Jmax25 and Vcmax25 declines with warming.

Batch and flow electrochemical methods enable direct C‐7 oxidation of abietic and dehydroabietic acids from colophony or their methyl derivatives to the corresponding ketones, while a mediated protocol enables additional C‐15 oxygenation, providing sustainable and selective routes to diversified abietane derivatives.

Abstract Soil water deficits in temperate forests are projected to become more frequent, more severe, and longer in duration. This study aims to quantify the current (1981–2010) and projected (2041–2070) exposure of 17 tree communities to soil water deficit (severity and duration) in southwestern Quebec, Canada, using the Canadian Land Surface Scheme ...
