Ecosphere, 2021 Populations of many species of grassland‐associated butterflies, moths, and bumblebees in the Great Plains of North America are experiencing steep declines due to habitat loss and degradation—primarily conversion of grasslands to row‐crop agriculture and

Communications Physics, 2019 The emergence of a fractal energy spectrum is the quintessence of the interplay between two periodic parameters with incommensurate length scales. crystals can emulate such interplay and also exhibit a topological bulk-boundary correspondence, enabled by

Metals, 2019 The present study investigates how the choice of characterization test and the composition of the stress state in terms of tension and shear can produce a non-unique failure locus in terms of stress triaxiality under plane stress conditions.

European Journal of Entomology, 2000 The large copper butterfly, Lycaena dispar batavus, a subspecies of much conservation interest, is host-specific to the great water dock, Rumex hydrolapathum, but little is known of the relationship between herbivore and host in wild populations.

CLASSIFICATION OF THE BUTTERFLIES [PDF]
The Canadian Entomologist, 1900 In the course of my already-published studies, the probabilities as to the homology of the last anal vein of the Papilionides primary have varied. From preparations of the pupal wing of the Hesperiades, it has become clear that the fork to second anal at base is the remains of the third anal vein, which is irregular and more extended in the fore wing ...

Adaptive evolution of butterfly wing shape: from morphology to behaviour
Biological Reviews of The Cambridge Philosophical Society, 2019 Butterflies display extreme variation in wing shape associated with tremendous ecological diversity. Disentangling the role of neutral versus adaptive processes in wing shape diversification remains a challenge for evolutionary biologists.

Nature, 1894 REFERRING to “Delta's” note, I may say that in the fine weather which we had here in April, the small tortoise-shell butterfly appeared more numerously than ever I had witnessed it at that season, or indeed at any time. I recollect counting a dozen at one time on a small bush of Andromeda floribunda then in flower.
