How patterns at the scale of small groups, large colonies or entire species emerge? Which is the role of individual behaviour?

Complex heterogeneous plumage traits has been elusive to old approaches. We quantify them with fractal geometry. We are finding fractal properties biologically relevant. We are now moving to multifractals.

Feather fault bars
Fault bars are feather-growth errors that weaken feathers. We are interested on the role of fault bars in bird evolution. We are now developing a semi-quantitative framework on the causes of fault bars based on a comprehensive review of literature.

Host-symbiont evolutionary ecology
How biodiversity emerge in host-symbiont systems? We are now studying the interaction between feather mites and passerine birds with massive parallel sequencing tools and networks analyses.
