Introduction
I study the paleoenvironments of prehistoric sites in the Mediterranean Levant. In my dissertation, I developed a paleoenvironmental model based on the diet of Mediterranean owls. I seek to describe whether specific prey taxa compositions charachterize habitats, and use these patterns for paleoecology. Addiitonally, I perform actuotaphonomic studies with birds of prey, aimed to describe their taphonomic signatures.

Article
Full-text available
Populations at the warm edge of distribution are more genetically diverse, and at the same time are more susceptible to climate change. Between 1987–1996, we studied Tawny Owls in Israel, the species’ global southern edge of distribution and a country undergoing a rapid land cover transformation for over a century. To assess the potential impacts o...

The design and successful performance of citizen science-based monitoring require an understanding of the motivation and the needs of participants. Herem we use a questionnaire to assess intrinsic and extrinsic motivations and investigate in links between project support service and motivations in 181 participants taking part in three insect-focuse...
Article
Full-text available
Butterflies are considered important indicators representing the state of biodiversity and key ecosystem functions, but their use as bioindicators requires a better understanding of how their observed response is linked to environmental factors. Moreover, better understanding how butterfly faunas vary with climate and land cover may be useful to es...
Article
Full-text available
Corrosion patterns induced by gastric fluids on the skeleton of prey animals may depend on the nature of the corrosive agents (acid, enzymes) as well as on the composition of the hard parts and the soft tissues that surround them. We propose a framework for predicting and interpreting corrosion patterns on lizard teeth, our model system, drawing on...
Article
Full-text available
Insects are the most ubiquitous and diverse group of eukaryotic organisms on Earth, forming a crucial link in terrestrial and freshwater food webs, but have recently made headlines because of observations of dramatic declines in some places. Although there are hundreds of long‐term insect monitoring programs, a global database for long‐term data on...

Butterfly Monitoring Schemes (BMSs) engage the public in conservation and provide data sets that cover broad geographical areas over long timescales. Most existing BMSs are in temperate climates; however, the Israeli Butterfly Monitoring Scheme (BMS‐IL), established in 2009, is a notable exception as it encompasses a large climatic gradient from Eu...
Article
Rodent agricultural pests cause significant food loss every year. Attempts at mitigation via chemical pest control may cause secondary poisoning and harm non‐target species. Biological pest control by bolstering barn owl Tyto alba populations through the provision of artificial nest boxes is in use in several countries. The national biological pest...
Article
This paper describes the micromammalian remains and paleoenvironment of the Upper Paleolithic sequence of Manot Cave (46-34 ka), southern Levant. Micromammal remains were identified from Ahmarian (46-42 ka), Levantine Aurignacian (38-34 ka) and post-Levantine Aurignacian (34-33 ka) layers. To identify taphonomic agents, molar digestion was modelled...
Article
Full-text available
The spectrum of glacial-interglacial environmental shifts in the southern Levant Mediterranean zone is evaluated based upon carbon isotopic records of speleothems from several caves, faunal records of Middle Paleolithic and Upper Paleolithic layers in caves, together with additional evidence from the base levels of the region. The studied evidence...
Article
Full-text available
Micromammal assemblages are often used in paleoecological reconstructions. However, in studies to date the environmental variables reconstructed were not shown to drive micromammal community structure before the reconstruction was attempted. Furthermore, the relative abundance data is too often dismissed despite its potential paleoecological value....
Article
Full-text available
Paleoenvironmental reconstructions based on micromammalian assemblages are a commonly used tool in paleoecology and zooarcheology. However, predator prey preferences may bias these assemblages to an unknown degree, thus leading to unreliable paleoenvironmental reconstructions. While attempts at taxonomically identifying micromammal predators throug...
Data
These are the raw data of the vertebrare prey taxa and abundances (as minimum number of individuals) of owl species in Israel, The West Bank and Golan Heights, as inferred from their pellets and bone accumulations at nesting and roosting sites. Some sites were visited more than once and data were pooled. Most data are from the years 2013-2015, but...
Article
Full-text available
Ecological theory suggests that prey size should increase with predator size, but this trend may be masked by other factors affecting prey selection, such as environmental constraints or specific prey preferences of predator species. Owls are an ideal case study for exploring how predator body size affects prey selection in the presence of other fa...
Article
The Mediterranean coast of Israel can be divided into two distinct provinces (south to north): the Nilotic, which up to the construction of the Aswan Dam received most of its quartz-rich sediments from the Nile, and the Levantine, which receives most of its sediments from local, carbonate-rich sources. These differences in sediment composition shou...
Article
The Yarqon is a slow-flowing Mediterranean stream with three ecologically distinct sections, with varying abiotic conditions and anthropogenic influences. We used the Yarqon as a test habitat to study the effect of flow on microbial communities. Stream water samples from three distinct abiotic conditions; "clean", "human-impacted" and brackish sect...

To study the processes damaging microfauna prey remains (mostly bones and teeth) by actualistic methods, such as predator feeding experiments.
Project
Israel is the Tawny Owl's (Strix aluco) southern edge of distribution. Global warming is expected to cause poleward shifts in species distributions, and hence the Tawny Owl is expected to become locally extinct. Here we describe the results of a decade long survey of Tawny Owls breeding success in the Upper Galilee, (northern Israel), as well as information on its natural history.
