Correctable or not? The case of plant epithets derived from the Elbrus/Elburs Mountains in Iran, with further notes on taxonomic grey literature

open access: yesTAXON, EarlyView.
Abstract Plant name epithets (as well as names of other organisms governed by the ICN), which are derived from geographic names, are not correctable when their original spelling was intentional and based on contemporary linguistic realities, even if it is currently considered outdated.

Nutrient addition, but not vertebrate predator exclusion, shapes arthropod communities and herbivory in a temperate forest

open access: yesEcological Entomology, EarlyView.
We experimentally manipulated top‐down (predator exclusion) and bottom‐up (fertilisation) forces in a temperate forest understory to test effects on arthropod densities, body sizes and herbivory. Predator exclusion had no detectable effect on arthropod density, herbivory damage or body size, whereas fertilisation increased herbivory damage and ...

Stronger expression of crassulacean acid metabolism (CAM) requires effective cuticular transpiration barriers but not necessarily strong succulence

open access: yesNew Phytologist, EarlyView.
Summary Discovering functional and evolutionary interdependencies of hydraulic traits and crassulacean acid metabolism (CAM) is crucial to understand CAM phenotype diversity and convergence. In complex traits such as CAM, the co‐option of associated traits strongly impacts the evolutionary outcome.
