Availability Of Microtrash Materials And Selectivity By California Condors, Marie G. Solis Jun 2019

Availability Of Microtrash Materials And Selectivity By California Condors, Marie G. Solis

Biological Sciences

California condors consume non-food items, including anthropogenic waste, and provision it to their young. Consuming “microtrash” can cause mortality, especially in nestlings. There are several hypotheses explaining why condors might consume microtrash. These hypotheses assume condors exhibit a preference for the type of material. Therefore, we test the assumption that when California condors take microtrash, they display material selectivity. We did this by sampling microtrash from roadside pullouts in the Los Padres National Forest. Those samples were compared to condor necropsy and nest microtrash data, categorized by material type: glass, plastic, metal, and other. We find that in our analysis ...

Membrane proteins make up approximately 30% of the cellular proteome and account for over 60% of pharmaceutical targets.1 Determining the structures of this class of proteins is critical to our understanding of disease states and will advance rational drug design. But membrane proteins have limited solubility, rarely form large crystals that diffract well, and often misfold outside of a bilayer, hindering crystallographic studies.1 Nanolipoprotein particles (NLPs) have arisen as a platform to readily solubilize membrane proteins while mimicking a native lipid environment. NLPs consist of a discoidal phospholipid bilayer encircled by an apolipoprotein belt. In an effort to ...
