Butterfly abundance declines over 20 years of systematic monitoring in Ohio, USA

open access: yesbioRxiv, 2019
Severe insect declines make headlines, but they are rarely based on systematic monitoring outside of Europe. We estimate the rate of change in total butterfly abundance and the population trends for 81 species using 21 years of systematic monitoring in ...

Chaos in the butterfly cone [PDF]

open access: yesJournal of High Energy Physics, 2019
A simple probe of chaos and operator growth in many-body quantum systems is the out of time ordered four point function. In a large class of local systems, the effects of chaos in this correlator build up exponentially fast inside the so called butterfly

Rainfall but not selective logging affect changes in abundance of tropical forest butterfly in Sabah, Borneo [PDF]

open access: yes, 2003
We investigated the effects of rainfall on the distribution and abundance of the satyrine butterfly Ragadia makuta in selectively logged and unlogged forest on Borneo. In 1997-98, there was a severe El Nino-Southern Oscillation (ENSO) drought, and annual

Evaluating costs of heavy metal tolerance in a widely distributed, invasive butterfly

open access: yesEvolutionary Applications, 2021
Organismal tolerance to environmental pollution is thought to be constrained by fitness costs, where variants with higher survival in polluted environments have lower performance in nonpolluted environments.

Butterfly species’ responses to urbanization: differing effects of human population density and built-up area

open access: yesUrban Ecosystems, 2020
Good knowledge on how increasing urbanization affects biodiversity is essential in order to preserve biodiversity in urban green spaces. We examined how urban development affects species richness and total abundance of butterflies as well as the ...

Range expansion, habitat use, and choosiness in a butterfly under climate change: Marginality and tolerance of oviposition site selection

open access: yesEcology and Evolution, 2021
Poleward range shifts under climate change involve the colonization of new sites and hence the foundation of new populations at the expanding edge. We studied oviposition site selection in a butterfly under range expansion (Lycaena dispar), a key process
