Constant Sexual Aggression Drives Female Tortoises to Walk Off Cliffs
On a remote island in North Macedonia, male Hermann’s tortoises outnumber females 19 to 1, an imbalance driving the population to extinction.

"researchers have found that the relentless males are driving their population to extinction."

Several fly larvae are crawling on an agar surface.

Several fly larvae are crawling on an agar surface.

The second paper from the lab is now available on bioRxiv: www.biorxiv.org/content/10.6...
We discovered that cannibalistic behavior in fly larvae is social-context dependent. Larval groups avoid dead conspecifics; individuals show high attraction. They only do it when no one is watching πŸ˜‰

Schematic of how ER-EPG plasticity enables the bump of activity in EPGs to accurately track visual cues. As a fly makes a counter-clockwise turn (top to bottom) it will view visual cues (e.g. the sun) from a new angle and the EPG activity bump (red) will swing clockwise around the network by integrating self motion signals with these visual inputs. When the fly faces a different angle, distinct visual ER neurons are active. Plasticity forms a trough of weak synapses (large circles - strong synapses, small circles - weak synapses) that allow ER neurons with distinct visual tuning to move the EPG bump via disinhibition.
