DOI: 10.1002/ece3.2895
Abstract: Abstract Leaves and absorptive roots (i.e., first‐order root) are above‐ and belowground plant organs related to resource acquisition; however, it is controversy over whether these two sets of functional traits vary in a coordinated manner.… read more here.

DOI: 10.1038/s41467-020-16839-9
Abstract: Recent studies show coordinated relationships between plant leaf traits and their capacity to predict ecosystem functions. However, how leaf traits will change within species and whether interspecific trait relationships will shift under future environmental changes… read more here.

DOI: 10.3390/math13233858
Abstract: Identifying item–trait relationships is a core task in multidimensional item response theory (MIRT). Common empirical approaches include exploratory item factor analysis (EIFA) with rotations, the expectation maximization-based L1 regularization (EML1) algorithm, and the expectation model… read more here.
