Nicky completed her MSc in 2017. Her research linked the effects of fine inorganic bed sediment and NZ fish community composition. Nicky also undertook some fish toxicology experiments looking at fish feeding rates under a range of turbidity conditions.
Jason completed his MSc in 2016. His research focused on investigating the impacts of heavy metals on macroinvertebrate communities in Christchurch's urban waterways. A field survey and mesocosm experiments along a heavy metal gradient identified heavy metals in the sediment as the strongest predictor of macroinvertebrate community structure in the sampled waterways.
Sophie completed her MSc in 2015. Her research focused on investigating effects of interacting global change drivers on native and exotic mosquito distributions. She found that climate-induced temperature changes combined with local habitat variables to determine mosquito presence.
Tom completed his MSc in 2015 investigating the distribution, occurrence and identification of mosquito larvae species in the Tongatapu Island Group. Nine mosquito species were collected, including the virulent Asian Tiger mosquito. This is only the second collection of this species in the Tongatapu Island Group and suggests that this mosquito has expanded its range since last collected in 2012. Human refuse including, abandoned car tyres, fuel drums and abandoned washing machines were amongst the most common habitats in which mosquito larvae were found. Increasing public awareness about mosquitoes and reducing human refuse may result in a reduction of the number of mosquitoes present throughout the Tongatapu Island Group.
Jon completed his PhD on the ecology of Didymosphenia geminata in 2014. Field surveys, and field and lab based experimental studies examined the biotic impacts of blooms; physical and chemical habitat associations; interspecific competition; aspects of cellular physiology, including mechanisms driving bloom development; the adaptive value of bloom formation; and aspects of invasion dynamics.
Mark completed his PhD in 2014 on generalist invertebrate life history strategies to persist across an unpredictable pond-permanence gradient. He used a combination of multi-year field surveys across the Canterbury high-country ponds, a series of mesocosm experiments at University of Canterbury’s Cass Field Station, and population genetics to estimate dispersal and population differentiation among pond types. He found different generalist species use contrasting strategies (developmental, growth and behavioural) to either, tolerate or avoid drying and predator stresses, thereby reducing selection pressures. Along with evidence of widespread dispersal among ponds, suggest that habitat generalists can readily exploit unpredictable environments.

Roseanna completed her BSc(Hons) in 2014. Her research focused on detecting current and historic marine nutrient subsidies in stream ecosystems. She used trace elements and stable isotopes of d13C and d15N to track current and historic Westland Petrel and NZ fur seal pup inputs to streams, as well as stoichiometry of C:N and N:P to assess stream nutrient limitation.

Elizabeth completed her PhD on the effects of eutrophication on stream food webs in 2014. She found that eutrophication was associated with greater numbers of invertebrates with morphological defenses, which created trophic bottlenecks and reduced energy flow through the food web. She also conducted a series of follow-up experiments investigating the effectiveness of organic matter additions as a potential restoration tool to mitigate the observed bottleneck effects in eutrophic streams.
Simon completed his PhD in 2014 researching how flow influences populations of threatened galaxiid fishes in Mackenzie Basin. Using a broad field survey he found that flow-related conditions, from multiple spatial scales, generally affected fish community composition in the region. Threatened galaxiid populations were also strongly influenced by local flow and flow-related conditions, and were likely vulnerable to changes in these flows via changes to habitat availability, and their interactions with introduced trout.
Tom completed his MSc in 2014 investigating nitrate-nitrogen stress on benthic invertebrate communities. He found biotic metrics were not sensitive to nitrate-nitrogen stress, although a subtle whole-community shift did occur. This reflected the inability of degraded and tolerant invertebrate communities to respond to nitrate-nitrogen stress.
Danladi Umar completed his PhD in 2014 which focused on the effects of land use on stream communities in highland tropical Nigeria. He worked with Prof. Jon Harding and Emeritus Prof. Mike Winterbourn to develop a photographic guide to freshwater invertebrates of the Mambilla Plateau, Nigeria. The book is meant for undergraduate students and researchers in freshwater ecology.
