Threatened by Legislative Conservationism? The Case of the Critically Endangered Aeolian Lizard

Frontiers in Ecology and Evolution, 2017
Species-based conservation legislation needs to be based on sound scientific data and updated taxonomic knowledge. European Union environmental legislation is among the most advanced in the world, yet there is not a clear and regular mechanism to update ...

Diatom‐Inspired 1D Immobile Robots Capable of 2D Collective Mobility

Advanced Intelligent Systems, EarlyView.
This study presents a diatom‐inspired robotic system that explores group coordination through limited physical interactions. The researchers tune groups of Barbots, simple robotic agents that possess neither individual mobility nor explicit communication capabilities, to achieve complex and adaptive collaboration based on environmental light.

The application of the habitats directive in Portugal

, 2007
A succinct review of the application of the Habitats Directive in Portugal is presented. Since 1971 until 2000 Portugal has defined approximately 8,8% of its territory as national protected areas. With the application of the Habitats Directive nature conservation policies extended to more than 17,4 % of the territory increasing by 98% and the knowledge

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 ...

Most habitat's and species' assessments in German Natura 2000 sites reflect unfavourable conservation states

Basic and Applied Ecology
The Convention on Biological Diversity aims to protect 30 % of the Earth’s land and marine surface to promote biodiversity. In the European Union, conservation areas are mainly placed under protection through the Habitats Directive.

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.

Linking community structure and climate vulnerability in desert plant assemblages of southern California

American Journal of Botany, EarlyView.
Abstract Premise Desert plant assemblages in southern California provide an opportunity to link patterns of community structure with climate‐driven vulnerability in a rapidly changing environment. California sustains an exceptionally diverse flora of approximately 4300 plant species, with 31% identified as endemic.

Animal models in molecular biology research: Challenges, ethical imperatives, and the path to human‐relevant translation

Animal Models and Experimental Medicine, EarlyView.
The graphical abstract shows how molecular biology research has shifted from using traditional animal models toward using methods that are more relevant to humans. It points out the main problems, differences between species, difficulty in reproducing results, moral issues, and lack of infrastructure that make translational accuracy harder to achieve ...

Fuzzy approaches provide improved spatial detection of coastal dune EU habitats

Ecological Informatics
Mapping habitats on coastal dunes, crucial yet highly vulnerable ecosystems, requires objectivity and repeatability, which are still lacking in the implementation of the Habitats Directive.
