Geographical patterns of chromosomal differentiation in the brachypterous grasshopper Podisma sapporensis (Orthoptera: Acrididae)

open access: yesEuropean Journal of Entomology, 2008
The distribution patterns of the X0/XX and neo-XY/neo-XX chromosome races, subraces, and "hybrids" between subraces of the grasshopper P. sapporensis were analyzed.

From models to management: Implementing the climate‐change refugia conservation cycle in national parks of the northeastern United States

open access: yesConservation Science and Practice, EarlyView.
We provide two case‐studies that incorporate climate‐change refugia into management at local and regional scales. We demonstrate methods to test refugia predictions and monitor effectiveness. We share lessons learned to help other practitioners and scientists incorporate climate‐change refugia into management.

From leaves to defenders: How the amount and dispersion of leaf damage affect extrafloral nectar production and ant‐mediated protection in wild cotton

open access: yesEcological Entomology, EarlyView.
Extrafloral nectar mediates interactions among plants, ants and herbivores; its contingency on damage amount and within‐plant uniformity is poorly understood. Here, we explore these factors in wild cotton (Gossypium hirsutum). Herbivory amount drove increases in extrafloral nectar induction per nectary, whereas within‐plant variability in damage ...

Spatial prediction of Melanoplus differentialis using an ensemble of multiple species distribution models

open access: yesInsect Conservation and Diversity, EarlyView.
Ensemble model using multiple niche models was constructed to globally identify regions at high risk for Melanoplus differentialis distribution under climate change. The occurrence possibility was found to be particularly high in its native region, the United States, and high invasion risk was identified in non‐native regions, particularly in Europe ...

The development of insect diversity and ecosystem complexity on green roofs: A review

open access: yesInsect Conservation and Diversity, EarlyView.
A classification system of different roof types is presented to improve consistency in green roof research. Landscape and green roof characteristics influence ecosystem development, but can be further explained by ecological concepts, like neutral and niche theory.

A RANGELAND GRASSHOPPER INSURANCE PROGRAM [PDF]

open access: yes
The incidence of benefits and costs from controlling rangeland grasshoppers on public grazing lands poses problems of economic efficiency and distributional equity. Public grasshopper control programs operate like public disaster assistance.
