Introduction
I am a zoologist and ecologist, my main interest and the source of the questions I pursue is animal behaviour. I study natural history, sensory ecology, and behaviour in bats, with detours to other topics and different organisms. I often use bioacoustics and controlled field experiments. in addition to pure research, I am deeply involved in conservation. I am now starting to work on the interactions between sensory individuality, ecology, and life-history traits.

Article
Full-text available
Animals execute sensorimotor sequences to optimize performance of complex actions series. However, the sensory aspects of these sequences and their dynamic control are often poorly understood. We trained bats to fly to targets at different distances, and analysed their sensory behavior before and during flight to test whether they assess target dis...
Article
Full-text available
Active-sensing systems such as echolocation provide animals with distinct advantages in dark environments. For social animals, however, like many bat species, active sensing can present problems as well: when many individuals emit bio-sonar calls simultaneously, detecting and recognizing the faint echoes generated by one's own calls amid the genera...
Article
Full-text available
We used radio-telemetry, observations and physiological measurements to study the basic biology and energetic strategies of Asellia tridens in northern Israel from 2009 to 2010. Between late May and early November, the bats occupied abandoned man-made structures in this area. Parturition occurred between late June and mid-July, and juveniles were i...

A comprehensive survey as a means to finding cryptic species.
Article
Animals must encode fundamental physical relationships in their brains. A heron plunging its head underwater to skewer a fish must correct for light refraction, an archerfish shooting down an insect must “consider” gravity, and an echolocating bat that is attacking prey must account for the speed of sound in order to assess its distance. Do animals...
Chapter
This comprehensive species-specific chapter covers all aspects of the mammalian biology, including paleontology, physiology, genetics, reproduction and development, ecology, habitat, diet, mortality, and behavior. The economic significance and management of mammals and future challenges for research and conservation are addressed as well. The chapt...
Article
Full-text available
Background Sensory systems acquire both external and internal information to guide behavior. Adjustments based on external input are much better documented and understood than internal-based sensory adaptations. When external input is not available, idiothetic—internal—cues become crucial for guiding behavior. Here, we take advantage of the rapid s...
Article
Full-text available
Infectious diseases can have devastating effects on populations, and the ability of a pathogen to persist in the environment can amplify these impacts. Understanding how environmental pathogen reservoirs influence the number of individuals that become infected and suffer mortality is essential for disease control and prevention. We integrated disea...

Abstract The use of artificial light at night (ALAN) is a rapidly expanding anthropogenic effect that transforms nightscapes throughout the world, causing light pollution that affects ecosystems in a myriad of ways. One of these is changing or shifting activity rhythms, largely synchronized by light cues. We used acoustic loggers to record and quan...
Article
Full-text available
Organ development, both in-utero and after birth, follows a different path for every organ depending upon how early the newborn will use it. Perception of the environment using echolocation occurs very early in the life of neonatal bats. In nostril-emitting echolocating bats of the families Hipposideridae and Rhinolophidae, the shape and area of th...

Thesis
Full-text available
Bats are one of the most wide-spread and species-rich orders of terrestrial vertebrates. They range from sub-arctic to tropical latitudes, and inhabit almost all habitats – from rainforests to deserts and everything in-between. They display a wide array of foraging tactics, social behaviours, vocal communication, navigational skills and learning ab...

The Trident Leaf-Nosed bat (Asellia tridens) is an insectivorous bat with a Saharo-Sindian global distribution that in the past was common throughout Israel and in the present is found mainly in the African Rift area. In spite of its wide distribution in the region the basic biology of this species has not been studied in detail and only a few stud...

Organisms display a hugely diverse and incredibly sophisticated array of sensory systems to extract information about their environment. Sensing the environment, however, is only one side of the story; to achieve its goals an animal must act upon the information gained by its senses. For echolocating bats, this requires sensorimotor integration ope...

Article
Full-text available
Active sensing, where sensory acquisition is actively modulated, is an inherent component of almost all sensory systems. Echolocating bats are a prime example of active sensing. They can rapidly adjust many of their biosonar parameters to optimize sensory acquisition. They dynamically adjust pulse design, pulse duration, and pulse rate within dozen...
Article
Full-text available
We report that two species of mouse-tailed bats (Rhinopoma microphyllum and R. cystops) hibernate for five months during winter in geothermally heated caves with stable high temperature (20°C). While hibernating, these bats do not feed or drink, even on warm nights when other bat species are active. We used thermo-sensitive transmitters to measure...
Article
Full-text available
Animals often deal with situations in which vast sensory input is received simultaneously. They therefore must possess sophisticated mechanisms to select important input and ignore the rest. In bat echolocation, this problem is at its extreme. Echolocating bats emit sound signals and analyse the returning echoes to sense their environment. Bats fro...
Article
Full-text available
Social foraging is a very common yet extremely complex behavior [1]. Numerous studies attempted to model it [2-7] with little supporting evidence. Studying it in the wild is difficult because it requires monitoring the animal's movement, its foraging success, and its interactions with conspecifics. We present a novel system that enables full night...

Article
Full-text available
Previous studies reported that fed bats and birds mostly use recently acquired exogenous nutrients as fuel for flight, rather than endogenous fuels, such as lipids or glycogen. However, this pattern of fuel use may be a simple size-related phenomenon because, to date, only small birds and bats have been studied with respect to the origin of metabol...
