Buzzing on top: Linking wild bee diversity, abundance and traits with green roof qualities

Green roofs are potentially valuable habitats for plants and animals in urban areas. Wild bees are important pollinators for crops and wild plants and may be enhanced by anthropogenic structures, but little is known about wild bees on green roofs …

Landscape urbanization threatens plant phylogenetic diversity in the Brazilian Atlantic Forest

Urbanization causes species loss around the world, but its effects on phylogenetic diversity are poorly known in tropical forests. Using a patch-landscape approach in an urbanizing region of the Brazilian Atlantic Forest, we tested whether the …

Determining species specific nightly bat activity in sites with varying urban intensity

Time of peak bat activity during the night differs among bat species due to temperature, prey availability, habitat availability, and/or interactions between species. Habitat availability is altered in urban areas, which may affect insect prey …

Ecohydrological model for the quantification of ecosystem services provided by urban street trees

Urban green spaces have been recognized as an important source of ecosystem services, whose quantification requires the determination of quantities related to energy, water, carbon and soil nutrient content. In this paper we propose a stochastic …

Herausforderung Elektromobilität für die Niederspannungsnetze – ein Bericht

Die stark zunehmende Zahl der Elektrofahrzeuge in Vorarlberg, Österreich, stellt die Niederspannungsnetze vor große Herausforderungen. Bereits bei geringen Durchdringungsraten kann es zu Grenzwertverletzungen bezüglich der Spannungen und Kabelauslastungen kommen. Besonders die steigenden Leistungsspitzen werden zukünftig hohe Netzinvestitionen mit sich bringen. Erste weitreichende Untersuchungen zeigen, dass eine hohe Durchdringungsrate nur integriert werden kann, wenn Ladestrategien weiterentwickelt und schrittweise in die Niederspannungsnetze etabliert werden. Um die Elektromobilität volkswirtschaftlich einbinden zu können, müssen dazu alle Interessensvertreter ihren Beitrag leisten.  Jetzt gratis downloaden!
