Dr. Anna McCallum is interested in the taxonomy and ecology of marine invertebrates. Over the last 10 years she has completed research in mangrove, seagrass and intertidal environments, but more recently her research has focussed on the deep and relatively unknown continental margins. She has expertise in the taxonomy of decapod crustaceans.
Anna first began work at Museum Victoria as a research assistant in 2005. Prior to this she completed an honours project investigating the effects of mangrove proximity on fishes in seagrass.
In 2011, Anna completed her PhD in marine ecology at the University of Melbourne. Her research described patterns of diversity along the continental margin and examined the importance of environmental and physical variables in shaping these patterns. This research was based on collections of decapod crustaceans from the continental margin of Western Australia.
Global deep sea biodiversity mapping
Anna’s current research aims to produce a global map of deep sea biodiversity based on the distribution of squat lobsters. Maps of the world’s seafloor fauna are long overdue and the most recent biogeographic classification of the deep sea relies on environmental surrogates. The lack of maps defined by faunal data hinders marine management across nations' EEZs and the high seas. This project collates data for over 1000 species of squat lobsters (superfamilies Chirostyloidea and Galatheoidea) from museum collections, the literature and other databases. Species distribution models will then be combined to produce global assemblage composition maps. This project is funded by the Census of Marine Life COSMOS award and is a collaboration of taxonomists worldwide.
Diversity patterns of benthic infauna on the continental margin
The small animals that inhabit the sediment of the ocean floor have long been used by ecologists to study spatial patterns of marine biodiversity. Recent efforts by a team of specialist taxonomists at Museum Victoria have resulted in a dataset of over 600 species across more than 50 sites on the continental margin. Anna is analysing this data to investigate patterns of diversity in relation to energy availability and habitat.
National Environmental Research Program (NERP) Marine Biodiversity Hub
Anna is a member of the Marine Biodiversity Hub, which provides scientific information and advice to support decision making in the marine environment at a national scale. Museum Victoria is providing information on spatial patterns of marine biodiversity. Anna is working on identifying collections from a recent expedition to the Oceanic Shoals Marine Reserve, Northern Territory.
