Height–diameter modeling of tree species in boreal and mixed forests using a mixed-effects approach and stand-level variables

Forest Science and Technology
Forests are ecologically complex, and trees play a structural and functional role in ecosystem dynamics. Tree height–DBH (diameter at breast height) relationships serve as a key indicator of forest productivity, competition, and succession, fundamental ...

Modelling individual tree diameter growth for Norway spruce in the Czech Republic using a generalized algebraic difference approach

Journal of Forest Science, 2017
Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective management of forests.

Predictors of Change in Severity of Self‐Injurious Behaviors in Preschool‐Aged Autistic Children

Autism Research, EarlyView.
ABSTRACT Self‐injurious behaviors (SIBs) affect up to 50% of autistic individuals and significantly impact quality of life and everyday functioning. Cross‐sectional studies link the presence of SIB to lower IQ, altered sensory responsivity, and poor emotion regulation, yet their effect on changes in SIB severity from early childhood to school age in ...
