Crop diversity and rotation may increase dispersal opportunities of reptiles in a heterogeneous agroecosystem

גיא רותם, ירון זיו

Land sharing strategies in agricultural landscapes need to allow for organisms to move between natural areas and different crops within an agro-ecological landscape in order to reduce extinction probability and the negative effects of small isolated populations. In this study, it was tested whether legume or wheat fields differed in their effects on reptiles’ movement patterns.

Decoupling Fragmentation from Habitat Loss for Spiders in Patchy Agricultural Landscapes

ירון זיו, יוני גביש, מיכאל רוזנצווייג

Habitat loss reduces species diversity, but the effect of habitat fragmentation on number of species is less clear because fragmentation generally accompanies loss of habitat. They compared four methods that aim to decouple the effects of fragmentation from the effects of habitat loss.

There is compelling evidence that more diverse ecosystems deliver greater benefits to people, and these ecosystem services have become a key argument for biodiversity conservation. However, it is unclear how much biodiversity is needed to deliver ecosystem services in a cost-effective way. Here they show that, while the contribution of wild bees to crop production is significant, service delivery is restricted to a limited subset of all known bee species.

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

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, Luísa Carvalheiro, Alexandra‐Maria Klein, Natacha Chacoff, Jan Dudenhöffer, Sarah Greenleaf, Andrea Holzschuh

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.

We develop a model to evaluate the profitability of controlling rodent damage by placing barn owl nesting boxes in agricultural areas.

A comparison of naturally growing vegetation vs. border-planted companion plants for sustaining parasitoids in pomegranate orchards

אלעד חיל, אלי הררי, תמר קיסר, מרים קישינבסקי

Diversification of vegetation within and around agricultural habitats is an effective strategy to support populations of natural enemies of crops’ pests. Such diversification can be achieved by conservation of natural vegetation that develops spontaneously around the plots, as well as by active introduction of companion plants to the crop. In this study we compared these two approaches in pomegranate orchards in Mediterranean climate.
