Improved Regression Tree Models Using Generalization Error‐Based Splitting Criteria

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Despite the widespread application of machine learning (ML) approaches such as the regression tree (RT) in the field of data‐driven optimization, overfitting may impair the effectiveness of ML models and thus hinder the deployment of ML for decision‐making.

Pollination biology and reproductive ecology of critically endangered endemic Campanula teucrioides in western Anatolia

open access: yesNordic Journal of Botany, EarlyView.
Campanula teucrioides Boiss. is a critically endangered species found in a single locality in western Turkey. Determining the population size of C. teucrioides and conducting reproductive biology studies are of great importance in determining the necessary strategy for the conservation of the species. The area where the plant distributed was determined

Ectomycorrhizal fungi and root water uptake respond independently to water availability

open access: yesOikos, EarlyView.
Temperate forests on their warm and dry distribution limits are expected to be most vulnerable to reductions in water availability. This prediction is mostly based on studies assessing single forest functions, mainly growth. Water and nutrient cycling are functions that rely on tree roots and their symbiotic association with ectomycorrhizal (ECM) fungi.

Winter wipeout? Post‐disturbance recovery of brown trout indicates strong population resilience to harsh winter conditions

open access: yesOikos, EarlyView.
Demographic resilience refers to the capacity of a population to resist and recover from disturbances in terms of both population size and structure. Resilience to severe disturbance events, such as heatwaves, floods, and cold snaps, is likely to vary with the life‐history characteristics of the population, such as migratory strategy, and demographic ...
