Use of an unmanned aerial-aquatic vehicle for acoustic sensing in freshwater ecosystems

Freshwater ecosystems are endangered, underfunded and understudied, making new methods such as passive acoustic monitoring (PAM) essential for improving the efficiency and effectiveness of data collection. However, many challenges are still to be addressed ...

Perimeter Control and Route Guidance of Multi-Region MFD Systems With Boundary Queues Using Colored Petri Nets

Nikolaos Geroliminis, Anastasios Kouvelas, Hui Fu

Perimeter control based on Macroscopic Fundamental Diagram (MFD) aims to meter the number of transferring vehicles at the periphery of the protected urban region in order to obtain the desired number of vehicles in that region. The advantage of perimeter c ...

New perspectives for spatial planning in Switzerland: the role of ecosystem services

Rémi Jaligot

Spatial planning deals with the spatial expression of human activities in an integrated way to minimize their negative impacts on the natural and land systems. Rapid land use and land cover changes are important drivers of change of the benefits people der ...

Greater Contribution From Agricultural Sources to Future Reactive Nitrogen Deposition in the United States

Athanasios Nenes, Shuai Shao

Many sensitive ecosystems in areas protected for biodiversity conservation in the United States suffer from exposure to excess reactive nitrogen (Nr) released by fossil fuel combustion and agricultural practices and deposited onto the land surface and wate ...

On the probabilistic nature of the species-area relation

Andrea Rinaldo, Andrea Giometto, Jonathan Giezendanner, Silvia Zaoli, Amos Maritan

The Species-Area Relation (SAR), which describes the increase in the number of species S with increasing area A, is under intense scrutiny in contemporary ecology, in particular to probe its reliability in predicting the number of species going extinct as ...

Cultural ecosystem services provision in response to urbanization in Cameroon

Jérôme Chenal, Armel Firmin Kemajou Mbianda, Rémi Jaligot

In Africa, cities are unable to accommodate population growth within their current administrative limits, putting pressure on ecosystem services (ES) in peripheral areas. Existing ES related studies in the region were conducted in East and South Africa, an ...

On species persistence-time distributions

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis, Amos Maritan

We present new theoretical and empirical results on the probability distributions of species persistence times in natural ecosystems. Persistence times, defined as the timespans occurring between species' colonization and local extinction in a given geogra ...

An efficient technique to accelerate the simulation of passive shielded microwave circuits

Juan Ramon Mosig, Michael Mattes, Laleh Golestanirad

An efficient algorithm is presented for simulating passive microstrip layouts consisting of arbitrary shaped circuitry embedded in a shielded stratified media using an area of influence (AI) approach with a full-wave integral-equation-based numerical solve ...

Stratégies villageoises pour la gestion des paysages forestiers du Menabe Central, Madagascar

Clémence Dirac Ramohavelo

Introduction In order to reduce deforestation, the current attitude of conservation programmes and forest politics does no longer ban the local populations from the forests, because such measures present negative consequences for the communities. Today's t ...

C(1 -> 4)-linked disaccharides through carbonylative Stille cross-coupling

Pierre Vogel, Peter Steunenberg

A tinglucal tributyl[4,6-O-bis(t-butyl)silylidene-3-O-tris(isopropyl)silyl]tin 7 and a triflate derived from isolevoglucosenone (1R,4R,5R)-4-benzyloxy-6,8-dioxabicyclo[3.2.1]oct-2-en-2-yl trifluoromethanesulfonate 10 undergo the carbonylative Stille conden ...
