Here, we present a protocol for 3D photogrammetry and morphological digitization of skulls, including complex ones with tusks, antlers, and horns, which are challenging to reconstruct digitally. We describe steps for setting up specimens for image acquisition, including camera and lighting configurations, and the subsequent image processing to generate high-quality 3D models. We also outline the extraction of morphological data for accurate geometric morphometric analyses.

Recent analyses of genome data indicate that members of the cyanobacterial order Pleurocapsales show tremendous potential for natural product discovery. However, only a few compounds have been reported from this order. Here, we report the isolation of hyellamide (1), a glycosylated N-acyl tyrosine-derived eneamide, from the pleurocapsalean cyanobacterium Hyella patelloidesLEGE 07179. The putative biosynthetic gene cluster for 1was identified in the genome of the producing organism and a biosynthetic proposal is presented. This work sheds light on the chemistry of the Pleurocapsales and expands the chemical repertoire of cyanobacterial natural products to include N-acyl tyrosine-derived molecules.
