Animal Biodiversity

Welcome! The Govindarajan lab studies the biodiversity and ecology of marine animals, especially the animals of the ocean's midwater. Towards that end, we use environmental DNA approaches to address questions related to diel vertical migration, food web interactions, and the biological carbon pump. Given the vast size of the ecosystem and the logistical challenges for studying deep water habitats, we develop and apply autonomous sampling approaches which we use in conjunction with a range of deep sea exploration platforms.

 

Specific research topics include:

 

  • Development and application of autonomous eDNA samplers with in situ filtration coupled with AUV, ROV, and towed platforms; including the development and application of autonomous adaptive sampling

 

  • Creating genetic reference databases for DNA barcoding and metabarcoding of mesopelagic fishes

 

  • Molecular systematics, phylogenetics, ecology and evolution of jellyfishes

  • Biodiversity exploration and diel vertical migration at Vailulu'u - We are exploring the biodiversity associated with the underwater volcano Vailulu'u, located near American Samoa and whether biological production associated with venting affects diel vertical migration of animals in the overlying water column. We are collecting eDNA samples with Mesobot and the Deep Autonomous Profiler to study how the volcanic activity animal life in the water column. Our expedition encompasses two oceanographic cruises (NA164 and NA165) on the E/V Nautilus. The image above shows Mesobot (represented by a small yellow triangle) sampling in the crater!
