... will impair olfaction. We performed electro-olfactograms on juvenile gilt-head seabream ( Sparus aurata ) and measured the response to three amino acids at five different concentrations (1×10 −7 to 1×10 −3 mol l −1 ) in normoxic (20 kPa O 2 ) and two hypoxic conditions (12.5 and 5.7 kPa O 2 ). For the first...

.... Lack of olfactory inputs during development causes a reduction in germline stem cells. Although germline stem cells proliferate normally, the germline cysts undergo caspase-mediated apoptosis, leading to decreased follicle production and egg-laying in flies with defective olfaction. Strikingly...

...Antoine Hoffmann; Einat Couzin-Fuchs ABSTRACT Motion plays an essential role in sensory acquisition. From changing the position in which information can be acquired to fine-scale probing and active sensing, animals actively control the way they interact with the environment. In olfaction, movement...

These results are nevertheless important as they set olfaction as a new player in the seasonal timing of reproduction in birds. Gonadal development might differ not only between the experimental and the control groups...
