This study was an endeavor to map out a personality trait structure of the Swahili language that may be used to develop indigenous eastern African personality assessment instruments. We followed the psycho-lexical approach where we not only identified trait terms from the Swahili dictionary but also from free descriptions collected from indigenous Swahili speakers. In combination, these two routines led to a pool of 3,732 personality-relevant terms, which was reduced in several steps to a set of 948 terms, identified as the most relevant trait-descriptive terms, including a small set of 26 adjectives, a large set of 531 nouns, and a substantial set of 391 verbs. This working set of 948 terms was lastly reduced to a final set of 661 most useful terms, converted into brief communicable sentences based on 439 nouns (comprising 250 type nouns and 189 attribute nouns), 199 verbs, and 23 adjectives. The list of 661 items was used to collect self and peer ratings from 480 university and high school students. An analysis of ratings on the 661 items revealed a six-factor personality trait structure that included Virtue, Imprudence, Negative Valence, Self-importance, Deceptiveness, and Attentive Conversation. Separate analyses were done using the type nouns, the attribute nouns, and the verbs, to assess the differential contribution of these word classes to the makeup of these Swahili Six.

Plant Species Richness and the Root Economics Space Drive Soil Fungal Communities.

Trait-based approaches have been increasingly used to relate plants to soil microbial communities. Using the recently described root economics space as an approach to explain the structure of soil-borne fungal communities, our study in a grassland diversity experiment reveals distinct root trait strategies at the plant community level. In addition to significant effects of plant species richness, we show that the collaboration and conservation gradient are strong drivers of the composition of the different guilds of soil fungi.

Evolutionary change within community members and shifts in species composition via species sorting contribute to community and trait dynamics. However, we do not understand when and how both processes contribute to community dynamics. Here, we estimated the contributions of species sorting and evolution over time (60 days) in bacterial communities of 24 species under selection by a ciliate predator.

Corner's rules are well known in describing inter-specific scaling relationships for plant organ size-related traits, from species with thick terminal stems, large leaves, and sparsely branched twigs to species with opposite traits; however, the implications of organ size on physiological functions and growth performance of trees remain unclear. Moreover, whether Corner's rules spectra differ between tree species with simple and compound leaves is not known. Here, we measured key twig morphological traits, physiological characteristics, and radial growth rates of 27 simple- and 6 compound-leaved tree species in a common garden in Northeast China.

Background: Triticale and tritipyrum as a new artificial cereal were investigated as potential stress-resistant alternatives within the Triticeae tribe due to their notable adaptability to environmental stresses.
Objectives: The first purpose of this study was to determine the genetic variation of 14 genotypes on physiological traits in arid and semi-arid climate of Yazd province on primary trans chromosomal tritipyrum (PTCT) lines, promising triticale lines, and Iranian and Afghan bread wheat cultivars, and the second purpose was to investigate the genetic diversity and classification of genotypes using start codon targeted (SCoT) markers.
Materials And Methods: The photosynthesis pigments, proline, and catalase enzyme activity of 14 genotypes were determined.

Eusociality, characterized by reproductive division of labor, cooperative brood care, and multi-generational cohabitation, represents a pinnacle of complex social evolution, most notably manifested within the Hymenoptera order including bees, ants, and wasps. The molecular underpinnings underlying these sophisticated social structures remain an enigma, with noncoding RNAs (ncRNAs) emerging as crucial regulatory players. This article delves into the roles of ncRNAs in exerting epigenetic control during the development and maintenance of Hymenopteran eusociality.
