Behavioural Response Thresholds in New Zealand Crab Megalopae to Ambient Underwater Sound
Behavioural Response Thresholds in New Zealand Crab Megalopae to Ambient Underwater Sound Jenni A. Stanley*, Craig A. Radford, Andrew G. Jeffs Leigh Marine Laboratory, University of Auckland, Warkworth, New Zealand Abstract A small number of studies have demonstrated that settlement stage decapod crustaceans are able to detect and exhibit swimming, settlement and metamorphosis responses to ambient underwater sound emanating from coastal reefs. However, the intensity of the acoustic cue required to initiate the settlement and metamorphosis response, and therefore the potential range over which this acoustic cue may operate, is not known. The current study determined the behavioural response thresholds of four species of New Zealand brachyuran crab megalopae by exposing them to different intensity levels of broadcast reef sound recorded from their preferred settlement habitat and from an unfavourable settlement habitat. Megalopae of the rocky-reef crab, Leptograpsus variegatus, exhibited the lowest behavioural response threshold (highest sensitivity), with a significant reduction in time to metamorphosis (TTM) when exposed to underwater reef sound with an intensity of 90 dB re 1 mPa and greater (100, 126 and 135 dB re 1 mPa). Megalopae of the mud crab, Austrohelice crassa, which settle in soft sediment habitats, exhibited no response to any of the underwater reef sound levels. All reef associated species exposed to sound levels from an unfavourable settlement habitat showed no significant change in TTM, even at intensities that were similar to their preferred reef sound for which reductions in TTM were observed. These results indicated that megalopae were able to discern and respond selectively to habitat-specific acoustic cues. -

CAWTHRON INSTITUTE | REPORT NO. 2741 NOVEMBER 2015 EXECUTIVE SUMMARY Cawthron Institute (Cawthron) was commissioned by the Marlborough District Council (MDC) to undertake state of the environment monitoring of the Wairau Estuary. This comprised an assessment of estuary condition or ‘health’ following the standardised Estuary Monitoring Protocol (EMP) (Robertson et al. 2002) and involved two ‘point in time’ surveys of the estuary based on: (1) Broad-scale vegetation and structural class habitat mapping (baseline for 20151) - with the additional trial use of a drone for aerial photography. (2) Fine-scale benthic surveys based on a suite of seabed characteristics at three reference sites within the estuary (baseline for 2015). Further funding (Envirolink 1588-MLDC105) allowed Cawthron to gather reminisces of the Wairau Estuary from local community members. -

August CONCHOLOGY SECTION AUCKLAND INSTITUTE & MUSEUM * ?*. v\, ) J i '1 V P 0 I R I E R I.A Vol. 7 Part 1 - August 1973 MODELIA GRANOSA Martyn ' , This turbinid mollusc can be found at and below low tide mark in both North and South Islands, though it most frequently occurs in the south of the South Island and at Chatham Islands where it is very common below low water among kelp and other seaweeds. Collectors beachcombing at Stewart Island usually return with some fine large examples - specimens of 5 inches diameter being sometimes obtained. Large numbers wash up after storms at Mason's Bay. Some of the largest seen have come from Chatham Islands. Many specimens are badly encrusted with coralline growth, but clean shells are pleasingly mottled with pink, brown and white and have a distinctly granulated spiral sculpture. The operculum is heavy, shelly and white with a finely granulated surface and an incised semicircular furrow near the margin i/'i/hile it is generally considered to be a southern shell, brightly coloured Modelia granosa axe found as far north as Gt. Exhibition Bay, but these specimens are very different in appearance from the southern shells. Seldom do they exceed one inch in diameter and the sculpture is much coarser, with large beads placed well apart. At times this shell is not uncommonly Washed up about the Bay of Islands, but live specimens are hard to obtain. An interesting item - from "The Link", February 1973, headed - "Snail Trapping Illegal" - "One of southern Switzerland's most popular weekend diversions, snail trapping, is now illegal.
