@AntCommunity 🐜 🐜 Chengyuan Liu found a Camponotus ant colony where all sexual larvae have red spots of various sizes, but worker larvae don’t. Any idea what this is?🤔 Video in the comment.

I definitely wasn’t early to the Listers party, but I’m glad I made it.

Now online! A de novo-originated gene drives rose scent diversification

A de novo-originated gene drives rose scent diversification

Genomic analysis of more than 100 Rosa species uncovers a multi-step process for the de novo origination of SCREP, a taxon-restricted gene specific to the Rosa genus, highlighting its function in modulating eugenol biosynthesis and driving rose scent diversification.

Piekarski: “"If some environmental factor affects caste, it will affect size too,” “…As far as we can tell, no matter which environmental variable you manipulate, the [genetically encoded] relationship between ant body size and caste remains unchanged"

Polyphenic traits in animals often exhibit nonlinear scaling with body size. Static allometries (i.e., scaling relationships) themselves can exhibi...
