Relative density of United States forests has shifted to higher levels over last two decades with important implications for future dynamics. [PDF]
Sci Rep, 2021 Tree size-density dynamics can inform key trends in forest productivity along with opportunities to increase ecosystem resiliency. Here, we employ a novel approach to estimate the relative density (RD, range 0–1) of any given forest based on its current ...

Density Peak Clustering Based on Relative Density Optimization [PDF]
Mathematical Problems in Engineering, 2020 Among numerous clustering algorithms, clustering by fast search and find of density peaks (DPC) is favoured because it is less affected by shapes and density structures of the data set.

Nest site preference depends on the relative density of conspecifics and heterospecifics in wild birds. [PDF]
Front Zool, 2017 BackgroundSocial learning allows animals to eavesdrop on ecologically relevant knowledge of competitors in their environment. This is especially important when selecting a habitat if individuals have relatively little personal information on habitat ...
