Frontoparietal Structural Connectivity in Childhood Predicts Development of Functional Connectivity and Reasoning Ability: A Large-Scale Longitudinal Investigation.

TL;DR: It is found that greater frontoparietal SC in childhood predicts future increases in both FC and reasoning ability, demonstrating the importance of white matter development during childhood for subsequent brain and cognitive functioning.
Journal ArticleDOI

Effects of land cover on ecosystem services in Tanzania: A spatial assessment of soil organic carbon

TL;DR: In this article, the authors used a combination of traditional analytical laboratory methods and mid-infrared spectroscopy (MIR) to quantify soil organic carbon (SOC) dynamics across various land uses in Tanzania.
Journal ArticleDOI

Foliar phosphorus fractions reveal how tropical plants maintain photosynthetic rates despite low soil phosphorus availability

TL;DR: It is indicated that tropical species acclimate to low P availability by altering allocation of foliar P to meet the demand of P for photosynthesis, and species typical of lowland tropical forests in East Asia maintained their photosynthetic rate underLow P availability.
Journal ArticleDOI

The role of ecological constraint in driving the evolution of avian song frequency across a latitudinal gradient.

TL;DR: Constraints on rates of vocal evolution are analyzed using a large dataset of New World avian sister taxa to show that species breeding in tropical forests sing at generally lower frequencies and across narrower bandwidths, and that song frequency has evolved more rapidly overall at high latitudes in both forest and open habitats.

Ranking yields of energy crops: A meta-analysis using direct and indirect comparisons

TL;DR: In this article, a large set of yield data obtained for 36 energy crop species and ranked these species according to their productivity was carried out and a statistical analysis based on direct and indirect comparisons was performed to compare the mean yield values of the species included in the database.
