Foraging behavior for hosts in parasitoids resembles that of predators with respect to finding, evaluating and manipulating of the prey. Host handling time may depend on the life history of the parasitoid and can be affected by oviposition experience. Additionally, handling time can be affected by host aggregation, species, size and state (parasitized or not). We studied handling times in the egg-larval parasitoid wasp Copidosoma koehleri. 

Controlled land spreading of olive mill wastewater (OMW) is now adopted in several Mediterranean countries as a practical alternative for its disposal.

The purpose of this study is to obtain a better understanding of groundwater contamination processes in an arid environment  due to cultivation.

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.

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. 

We studied the diet of 20 Barn Owl (Tyto alba) pairs breeding in three habitats (alfalfa fields, date plantations, and villages) in the same agricultural region in the Jordan Valley, Israel.
