Diversity within species

4 #sympatric #ecomorphs of #ArcticCharr reside in Lake #Þingvallavatn #iceland

Split on size and habitat, head morphology

😊 📢🎶🕸️🕷️ New preprint!

Multiple paths towards repeated phenotypic #evolution in the spiny-leg #adaptive #radiation (Tetragnatha; Hawaii)

Tetragnatha, similar to the Anolis #adaptive #radiation(s), are ' organized ' into #ecomorphs (habitat):

Green (leaf-habitat)
Maroon (mosses)
Small brown (twigs)
Large brown (tree bark)

Manuscript on #craniofacial variation in #sympatric #ecomorphs of #ArcticCharr

This darling is nearly ready for submission. Very cool results from a study led by Guðbjörg Ósk Jónsdóttir and Sarah Steele, based on pioneering work by Finnur Ingimarsson and Sigurður S. Snorrason.

Diversity in the internal functional feeding elements of sympatric morphs of Arctic charr (Salvelinus alpinus)

This year all four of my #MscBiology students graduated

Two of them are here in the middle
