Jess Harm did her PhD at Oxford with field support from the Operation Wallacea Honduras marine research programme. Her thesis title was “The Relationship Between Coral Reef Fish (Larvae, Juveniles, and Adults) and Mangroves: A Case Study in Honduras”. She investigated several questions including: will an island with mangrove lagoons house a different fish assemblage than an island without mangrove lagoons? Are fish in mangrove lagoons distributed according to differences in abiotic (salinity, dissolved O2, nutrients) and biotic (presence of filter feeders and algae) factors? What mangrove prop-root characteristics attract coral-reef fish juveniles?
