Plant nutrient‐acquisition strategies contribute to species replacement during primary succession

open access: yesJournal of Ecology, Volume 113, Issue 4, Page 988-1003, April 2025.
Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.

A comparative study of monotone nonparametric kernel estimates [PDF]

open access: yes
In this paper we present a detailed numerical comparison of three monotone nonparametric kernel regression estimates, which isotonize a nonparametric curve estimator. The first estimate is the classical smoothed isotone estimate of Brunk (1958).

Convergence analysis of generalized iteratively reweighted least squares algorithms on convex function spaces [PDF]

open access: yes
The computation of robust regression estimates often relies on minimization of a convex functional on a convex set. In this paper we discuss a general technique for a large class of convex functionals to compute the minimizers iteratively which is ...
