Preferential attachment with location-based choice: Degree distribution in the noncondensation phase

open access: yes, 2019
We consider the preferential attachment model with location-based choice introduced by Haslegrave, Jordan and Yarrow as a model in which condensation phenomena can occur [Haslegrave et al. 2018].

Improvements in turfgrass color and density resulting from comprehensive soil diagnostics [PDF]

open access: yes, 2001
There are roughly 220 golf courses in Arkansas, and as many as 50% of these courses were constructed using common bermudagrass fairways. Although resilient, common bermudagrass loses density and quality over time. In this experiment physical and chemical

Detection of refuge from enemies through phenological mismatching in multitrophic interactions requires season-wide estimation of host abundance [PDF]

open access: yes
The concept of ‘‘enemy-free space’’ (EFS) refers to ways of living that reduce or eliminate the vulnerability of a species to natural enemies. It has been invoked to explain host shifts of phytophagous insects.
