We studied the survival of discarded sandbar sharks from longline fishing. All satellite-tagged sandbar sharks survived. We found that blood hormones are suited to assessing survival with shorter time on hook, and lactate concentrations suited to longer time on hook. Tagged sandbar sharks showed diel patterns in their vertical behaviours, mimicking patterns seen in prey food items.

Water pumps fitted with screens to restrict invasive fish species from entering wetlands during managed watering events can benefit wetland biodiversity; yet, the benefits to floodplain frogs are unknown. In this study, frog and fish communities were compared between wetlands under managed inundation v. overland reconnections. Our results have broad implications for recovering frog population and small-bodied native fish in regulated floodplain systems.

This study evaluated the effects of increasing temperature on energy available for growth of Pāua (Haliotis iris) in New Zealand and their physiology, including absorbed energy, respiration energy and ammonia excretion energy. With ongoing global warming, it can be concluded that adult Pāua could be under severe stress and divert their energy away from growth by increase in respiration energy.

We investigated the phenology (reproductive timing in relation to environmental conditions) in two New Zealand parasitic freshwater mussel species. Our study demonstrated that Echyridella aucklandica reproduces earlier and longer than does E. menziesii, with temperature playing a key role in regulating the onset of reproductive activity in both species. The demonstrated link between temperature and reproductive phenology has broad implications in the context of climate change, raising concerns about potential timing mismatches in glochidia release and host-fish availability.
