Changes in benthic ecosystem properties and functions across sedimentary gradients in estuaries
(University of Waikato, 2014)In estuaries, sediment properties dominate the inhabiting flora and fauna and their role in energy flows and nutrient cycling. Whilst sediment transport is a natural, key process, human intervention in estuaries and their ... -
The context-specific roles of a bioturbating crab (Austrohelice crassa) on ecosystem functioning
(University of Waikato, 2011)Bioturbating macrofauna can have major effects on their physical, biological and biogeochemical surroundings, altering ecosystem functioning. Austrohelice crassa (herein Austrohelice) is a burrow building estuarine crab ... -
Denitrification response to nutrient enrichment in New Zealand estuaries
(The University of Waikato, 2018)As coastal catchment land use intensifies, estuaries receive increased nutrient and sediment loads, resulting in habitats dominated by muddy organic-rich sediments. Nutrient processing and denitrification in estuarine ... -
Effects of macrofauna diversity on porewater nutrient concentrations following enrichment
(University of Waikato, 2015)Macrofauna play a key role in the functioning of soft sediment intertidal ecosystems via bioturbation and feeding habits which modify sediment biogeochemistry and influence nutrient cycling. Eutrophication is a naturally ... -
Spatial variation in functional group diversity in a sandflat benthic community: implications for ecosystem resilience
(University of Waikato, 2013)The resilience of macrobenthic communities to environmental stress depends upon the vulnerability, adaptability and connectivity of species. Recent studies suggest that the function(s) species perform may be more influential ... -
The effects of terrigenous sediment on the behaviour of Macomona liliana (Bivalvia) in permeable sediments: Implications for porewater exchange
(University of Waikato, 2013)Catastrophic sedimentation events create one off disturbances that can cause mass mortality events in receiving estuaries. In contrast, the deposition of small amounts of terrigenous sediment (TS) is on-going and likely ... -
The influence of interacting stressors on soft sediment ecosystem function
(The University of Waikato, 2021)Soft sediment intertidal habitats provide valuable ecosystem services to millions of people worldwide yet are under intense anthropogenic pressure. In particular, the intensification of land derived sediment and nutrient ...
