Butterfly Species Richness Patterns in Canada: Energy, Heterogeneity, and the Potential Consequences of Climate Change

open access: yesEcology and Society, 2001
The distributions of most pollinator species are poorly documented despite their importance in providing ecosystem services. While these and other organisms are threatened by many aspects of the human enterprise, anthropogenic climate change is ...

Elliptic butterflies

open access: yesJournal of Complexity
We study natural evaluation and interpolation problems for elliptic functions and prove that they allow a recursive treatment using a variant of classical butterflies first introduced by Gauss. We deduce the existence of straight-line programs with complexity scaling with $d\log(d)$ for these problems and present applications to finite field arithmetic,

Interlayer‐Sliding‐Enabled Multiferroicity and Giant Switchable Anomalous Hall Conductivity in RuO2Zn2F2 Bilayer

open access: yesAdvanced Science, EarlyView.
Interlayer sliding in the RuO2Zn2F2 bilayer induces ferroelectricity and enables reversible valley polarization switching. The electric dipole and valley‐resolved band edges are intimately coupled, revealing sliding ferroelectricity as a powerful mechanism for electrical control of valley degrees of freedom in 2D materials.

Temporal variation in fruit-feeding forest butterfly communities in Sabah, Borneo. [PDF]

open access: yes, 2001
This study investigated temporal variation in fruit-feeding butterfly communities in Sabah, Borneo. Fruit-baited traps were used to sample butterflies in primary forest and forest that had been selectively logged 11-12 years previously in 1988 and 1989.

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors

open access: yesAdvanced Science, EarlyView.
This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

Quantifying the value of trees outside woods for promoting biodiversity on farmland

open access: yesEcological Solutions and Evidence
Within the farmed landscape, trees outside woods (TOWs), such as hedgerows, copses and scattered trees, provide a variety of benefits for wildlife and people, but these are not well understood or recognised.

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

open access: yesAdvanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

THE NISONIADES BUTTERFLIES [PDF]

open access: yesThe Canadian Entomologist, 1871
I write no less to elicit information, than to offer such as my limited material affords. In a very interesting and origional paper on Asymmetry, published by the Boston Soc. Nat. Hist. 1869-71, Messrs. Scudder and Burgess describe and figure the genital armor of all our species of Nisoniades, making seventeen species, of which nine are new.
