Summary

 
<https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-bi
ology/invasive-species> Invasive species threaten biodiversity and ecosystem
functioning. We develop an innovative experimental approach, integrating
biologically inspired robotics, time-series analysis, and
<https://www.sciencedirect.com/topics/engineering/computervision> computer
vision, to build a detailed profile of the effects of non-lethal stress on
the ecology and evolution of
<https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-bi
ology/gambusia> mosquitofish (
<https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-bi
ology/gambusia-holbrooki> Gambusia holbrooki)-a global pest. We reveal that
brief exposures to a robotic predator alter mosquitofish behavior,
increasing fear and stress responses, and mitigate the impact of
mosquitofish on native
<https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-bi
ology/tadpole> tadpoles (
<https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-bi
ology/litoria> Litoria moorei) in a cause-and-effect fashion. Effects of
<https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-bi
ology/predation-risk> predation risk from the robot carry over to routine
activity and feeding rate of mosquitofish weeks after exposure, resulting in
weight loss, variation in body shape, and reduction in the fertility of both
sexes-impairing survival, reproduction, and ecological success. We
capitalize on evolved responses of mosquitofish to reduce predation
risk-neglected in biological control practices-and provide scientific
foundations for widespread use of state-of-the-art robotics in ecology and
evolution research.

revealed by robots

 

Hi all,

 

In case this might be of interest for some, my colleagues and I have
recently published a paper on the potential impacts of stress and fear (from
next generation bioinspired robots) on the behaviour, ecology and evolution
of the invasive mosquitofish, Gambusia holbrooki. If you are interested, the
study is open access @
<https://www.sciencedirect.com/science/article/pii/S2589004221015005?via%3Di
hub>

ub 

 

The approach does not intend to eradicate mosquitofish in the wild, but
rather a proof of concept to inform and potentially improve biocontrol
practices. 

 

Have a great Xmas break all,

Giovanni
