"If human beings were not so impressed by size alone,
they would consider an ant more wonderful than a rhinoceros"

(E.O Wilson)

Arthropods are the most diverse group of animals in terrestrial systems, accounting for over 70% of all known organisms. They inhabit a vast variety of niches across wide spatial scales and exhibit a variety of feeding habits and life forms that,  after the plants, constitute a basis for most terrestrial food webs. Because of their high and fast reproduction rate, arthropod communities are sensitive to both short- and long-term environmental changes. Because large numbers of arthropod specimens and species can be efficiently collected, the group is utilized as a rich data source for ecological monitoring and ecosystem management.  

The Entomology Lab for Ecological Monitoring was founded in spring 2014 within the Steinhardt Museum of Natural History. Current studies in the lab focus on conservation and ecological management questions, utilizing arthropods as a sensitive tool for the assessment of ecological quality and ecosystem response to anthropogenic activities. Assessment includes multivariate analysis of community structure and composition, integrating various ecological indices and experimental approaches. Taxonomic identification is carried out according to the specific analysis in each research. The identification is based on the National Collection of Insects and its relevant experts, as well as on worldwide experts of different insect groups. The large-scale arthropod sampling, which is carried out at different sites, in different seasons, and using a variety of methods, supplements the collection with valuable specimens: rare, new to the Israeli fauna, and new species for science.

The lab’s activity spans geographically from Ramot Yissakhar in the north to Sedom, south of the Dead Sea. Current research being performed in the lab includes the monitoring of arthropod communities on the borders between agricultural and natural landscapes and ecological corridors, providing operational recommendations for management restoration in national parks; estimating the impacts of local anthropogenic pressure on sensitive ecological systems; and monitoring the populations of a rare butterfly. 

Projects are carried out in collaboration with The Israel Nature and Parks Authority, The Society for the Protection of Nature in Israel, Israel’s National Ecosystem Management Assessment Program, the Ministry of Environmental Protection, Ramat Hanadiv, and regional councils. We aim to provide a high-resolution tool able to contribute to a greater understanding of ecological systems, in order to aid the ongoing efforts to conserve  Israel's biodiversity.
