Sperm Sizer: a program to semi-automate the measurement of sperm length

, 2021
Research on sperm is incorporated into many areas of ecology and evolution including sexual selection, reproductive physiology and ecotoxicology, as well as comparative studies in evolution and phylogenetics. Currently, producing data on sperm morphology

Competition over guarding in the Arabian babbler (Turdoides squamiceps), a cooperative breeder [version 2; referees: 2 approved, 1 approved with reservations]

F1000Research, 2016
Observations on 12 groups comprised of two adult males and one adult female (some included one or two fledglings), tame, individually marked, Arabian babblers (Turdoides squamiceps) in the rift valley in Israel revealed that the babblers compete to guard.

Unlearned adaptive responses to heterospecific referential alarm calls in two bird species from separate evolutionary lineages

Scientific Reports, 2023
The interspecific responses to alarm signals may be based on unlearned mechanisms but research is often constrained by the difficulties in differentiating between unlearned and learned responses in natural situations.

Sex-specific effects of psychoactive pollution on behavioral individuality and plasticity in fish [Elektronisk resurs]

, 2023
Lay Summary Prozac is present in freshwater systems across the globe as the pharmaceutical contaminant fluoxetine. The effect of fluoxetine on aquatic species' behavioral variability is not yet clear. We show that male guppies become more similar to each
