An upgraded key for identifying all native species, subspecies and varieties of the genus Carex (Cyperaceae) in Europe and the Caucasus

Nordic Journal of Botany, EarlyView.
The last pan‐European key to Carex taxa was published in 1980 by Chater. Since that time several new species have been described, and numerous nomenclatural changes, including the recognition that the former genus Kobresia should be incorporated into Carex as C. subg. Euthyceras, have been made. This article provides a comprehensive key to identify all

The uniqueness of the human brain: a review [PDF]

Dementia & Neuropsychologia
The purpose of this review is to highlight the most important aspects of the anatomical and functional uniqueness of the human brain. For this, a comparison is made between our brains and those of our closest ancestors (chimpanzees and bonobos) and human

Adaptation in Wood Anatomical Traits to Temperature and Precipitation—A Common Garden Study

Plant, Cell &Environment, EarlyView.
ABSTRACT Indisputably, temperature and precipitation are key environmental variables driving plant trait variation and shaping plant ecological strategies. However, it is challenging to ascertain their relative influences because site temperature and precipitation are often correlated.

Gestural Iconicity and Alignment as Steps in the Evolution of Language

Topics in Cognitive Science, EarlyView.
Abstract Studies of the evolution of language rely heavily on comparisons to nonhuman primates, particularly the gestural communication of nonhuman apes. Differences between human and ape gestures are largely ones of degree rather than kind. For example, while human gestures are more flexible, ape gestures are not inflexible.
