Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.8341

Abstract: Abstract The species‐range size distribution is a product of speciation, transformation of range‐sizes, and extinction. Previous empirical studies showed that it has a left‐skewed lognormal‐like distribution. We developed a new mathematical framework to study species‐range‐size… read more here.

Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.9087

Abstract: Abstract An organism's body size plays an important role in ecological interactions such as predator–prey relationships. As predators are typically larger than their prey, this often leads to a strong positive relationship between body size… read more here.

Published in 2018 at "Atmospheric Pollution Research"

DOI: 10.1016/j.apr.2018.01.008

Abstract: Abstract High-traffic roadways substantially contribute to UFP number concentrations and size distributions within many urban areas and may contribute to excess urban mortality and morbidity. A number of previous studies have quantified near-road concentrations of… read more here.
