Parallel adaptation prompted core-periphery divergence of Ammopiptanthus mongolicus
Frontiers in Plant Science, 2022 Range expansion requires peripheral populations to shift adaptive optima to breach range boundaries. Opportunities for range expansion can be assessed by investigating the associations of core-periphery environmental and genetic differences.

Pesquisa Agropecuária Brasileira, 2009 The objective of this work was to assess the effects of a forest-field ecotone on earthworm assemblages. Five sites (blocks) differing in the type of crop rotation used in the field were studied in Central Bohemia, Czech Republic. In each block, sampling

Ecotone effect on the fruit fly assemblages (Diptera: Tephritidae) in natural and anthropized environments [PDF]
Brazilian Journal of Biology, 2023 Various species of fruit flies are important pests of fruit cultures and in some crop of vegetables worldwide. Studies of their population patterns, ecological processes and mechanisms that influence their sampling and distribution in the ecosystems ...

Physical Review Letters, 2006 We compute Casimir forces in open geometries with edges, involving parallel as well as perpendicular semi-infinite plates. We focus on Casimir configurations which are governed by a unique dimensional scaling law with a universal coefficient. With the aid of worldline numerics, we determine this coefficient for various geometries for the case of scalar-

Dynamics of Dissipative Quantum Hall Edges [PDF]
, 2003 We examine the influence of the edge electronic density profile and of dissipation on edge magnetoplasmons in the quantum Hall regime, in a semiclassical calculation.

Edge-induced spin polarization in two-dimensional electron gas [PDF]
, 2010 We characterize the role of the spin-orbit coupling between electrons and the confining potential of the edge in nonequilibrium two-dimensional homogeneous electronic gas. We derive a simple analytical result for the magnitude of the current-induced spin

Global-Scale Patterns of Forest Fragmentation
Ecology and Society, 2000 We report an analysis of forest fragmentation based on 1-km resolution land-cover maps for the globe. Measurements in analysis windows from 81 km 2 (9 x 9 pixels, "small" scale) to 59,049 km 2 (243 x 243 pixels, "large" scale) were used to characterize ...

Ecosphere, 2021 Human land use is fragmenting forests around the globe, increasing the edge density in forest landscapes. More frequent natural disturbances also increase the presence of edges in forest ecosystems.

Zero-field dissipationless chiral edge transport and the nature of dissipation in the quantum anomalous Hall state [PDF]
, 2015 The quantum anomalous Hall (QAH) effect is predicted to possess, at zero magnetic field, chiral edge channels that conduct spin polarized current without dissipation.
