The deep-sea is a dynamic and complex ecosystem influenced by environment and biology that is found there. Larval ecology, which refers to understanding the life-histories of larvae as well as studying what factors influence larval processes such as dispersal and recruitment, is a growing area of research in deep-sea ecology, and lends itself well to looking at how marine communities change with time and space – and underscores that the deep-sea is anything but static. Larval supply, which is the abundance of available larvae in an area, is directly related to the benthic species assemblage which eventually colonizes the area and settles. However, this relationship can be broken down by environmental influences, such as currents, substrate type, and energy availability (the later which is limiting in the deep-sea), and biological interactions, such as predation. For example, substrates which are more complex can provide refugia from predation, capture particles from the water column which in turn supplies more nutrients for colonizing species, as well as provide space and area for organisms to live.

My independent research project looks at trends in larval supply and colonization over space and time at deep-sea environments in Barkley Canyon, a submarine canyon on the western coast of Canada. Specifically, we are trying to characterize shifts in community composition as well as determine how colonizer and supply communities are influenced by different substrate types and environmental gradients.
