Natural habitat does not mediate vertebrate seed predation as an ecosystem dis-service to agriculture

יעל מנדליק, Alexandra‐Maria Klein, Jessica Schäckermann, נועם וייס, Henrik von Wehrden

It was studied whether vertebrates and their impact in crop seed predation are related to the percentage of natural (chaparral) and semi-natural habitat (planted forest with native and exotic trees) in an agricultural landscape of Israel.

Agro-ecosystem services and dis-services in almond orchards are differentially influenced by the surrounding landscape

יעל מנדליק, Alexandra‐Maria Klein, Jessica Schäckermann, Gesine Pufal

It was tested how natural and semi-natural habitats surrounding almond orchards in Israel influence: pest control services by parasitoids, pest predation dis-services by the Almond wasp, and seed predation dis-services by granivorous birds.

A global quantitative synthesis of local and landscape effects on wild bee pollinators in agroecosystems

Luísa Carvalheiro, Alexandra‐Maria Klein, Natacha Chacoff, Jan Dudenhöffer, Sarah Greenleaf, Andrea Holzschuh, Rufus Isaacs, Kristin Krewenka, Margaret M. Mayfield, יעל מנדליק, Lora Morandin, Lucas Garibaldi, Simon Potts, Ingolf Steffan‐Dewenter, Taylor Ricketts, Claire Kremen, Hajnalka Szentgyörgyi, Juan Morales, Blandina Viana, Riccardo Bommarco, Catrin Westphal, Saul Cunningham, Rachael Winfree

Bees provide essential pollination services that are potentially affected both by local farm management and the surrounding landscape. To better understand these different factors, they modelled the relative effects of landscape composition , landscape configuration and farm management, and their interactions, on wild bee abundance and richness for 39 crop systems globally.
