A modified allomone collecting apparatus was designed that could be used under water with a scuba tank. This apparatus provides a simple method of obtaining naturally secreted chemicals from benthic marine organisms at scuba depths, for the first time without the necessity of using a bilge pump. Organic material from Sep-paks in the allomone collector confirmed the release of secondary metabolites from a soft coral into the surrounding water.

The presence of androgens in female development is an important, yet often overlooked, topic. We tested for the presence of androgen receptors (ARs) in the dermal glands of male and female , a plethodontid salamander. This species engages in a courtship behavior called the tail-straddling walk.

Microorganisms symbiotic with insects, whether permanently or temporarily, play a crucial role in the nutrition, development, reproduction, defence, and metamorphosis regulation. In some Lepidoptera, oviposition-deterrent pheromones (ODPs) on egg surface were used by pregnant females to modify the behaviour of conspecifics to avoid excessive competition for limited resources. In this study, we constructed four different groups, including, OH, OA, SH, and OA, which either feed on different hosts or grow in different environments.

Species of the dinoflagellate genus Alexandrium can release bioactive extracellular compounds with allelopathic effects (e.g., immobilization, inhibition of growth, photosynthesis or lysis) towards other phytoplanktonic organisms.

Odorant metabolizing enzymes, considered as critical olfactory perireceptor actors, control the odor molecules reaching the olfactory epithelium by biotransforming them. As an odorant, the mammary pheromone, i.e.
