Project description:Glacier ice algae of the streptophyte genus Ancylonema live on glaciers globally, including the Greenland Ice Sheet. Each summer these algae bloom despite freezing temperatures, low nutrient availability, and very high light intensities. These algae also survive continual darkness during polar night. However, little is known about the cellular mechanisms underpinning glacier ice algae resistance and adaptation to high light or how they survive during dark periods. To address this knowledge gap, we evaluated the response of Ancylonema-dominated samples from the Greenland Ice Sheet to light and dark conditions over a 12-day incubation experiment using combined multi-omics analyses: amplicon sequencing, metatranscriptomics, and metaproteomics.
Project description:To explore the bacterial community profile of the gut of the African palm weevil and to identify the abundance and diversity of lignin degradation-associated bacteria in each gut segment.
