Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors

Advanced Intelligent Systems, EarlyView.
We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

Cost, risk, landscape context, and potential treatments vary with biological value for conservation of declining grassland birds

Conservation Science and Practice
Spatially explicit models are an important component of systematic conservation planning, enabling the depiction of biodiversity metrics across landscapes and objective evaluation of candidate sites for conservation delivery.

Habitat Conservation Plans

Texas A&M Journal of Property Law, 2013
Both sides of the debate have strong reasons for disliking section 10. After a brief discussion of HCPs and their history in Part II, this Comment will evaluate the best arguments from both landowners and preservationists in Parts III and V. Parts IV and VI will discuss case history supporting both sides.

Targets for maintenance of dead wood for biodiversity conservation based on extinction thresholds [PDF]

, 2006
Forestry decreases the amount of dead wood, thereby threatening the persistence of many saproxylic (wood-living) organisms. In this article, we discuss how targets for efforts to maintain and restore dead wood in managed forest landscapes should be ...

Uncovering renewable energy policy impact channels on land values, the local farm structure, and farmland heterogeneity

American Journal of Agricultural Economics, EarlyView.
Abstract Germany's Renewable Energy Sources Act (REA), enacted in 2000 and subsequently amended, subsidized national renewable energy production with fixed feed‐in tariffs for renewable energy sources (RE) from wind, solar, and biogas. Empirical studies suggest that the policy was creating windfall effects for landowners and attribute farmland use ...

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

American Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Private landowner interest in market‐based incentive programs for endangered species habitat conservation

Wildlife Society Bulletin, 2012
More than 75% of endangered species in the United States rely on private lands for habitat. Although this habitat has long been regulated under the Endangered Species Act, there is now broad agreement that economic incentives are also needed for ...

Variation in habitat preference and distribution of harbour porpoises west of Scotland [PDF]

, 2011
The waters off the west coast of Scotland have one of the highest densities of harbour porpoise (Phocoena phocoena) in Europe. Harbour porpoise are listed under Annex II of the EU Habitats Directive, requiring the designation of Special Areas of ...
