title: Comparison of injuries to New Zealand rock lobsters (Jasus edwardsii) caused by hand versus snare collection

authors: Powrie, Warrick

subjects: autotomy

abstract: Following the prohibition in New Zealand of lobster snares in late 2005, we undertook research to compare the frequency and extent of injuries to rock lobsters (Jasus edwardsii) (Hutton) caused by recreational SCUBA divers using lobster snares compared with hand collection. Rock lobsters were sampled between January 2006 and October 2006 from multiple dive sites around the North Island of New Zealand. Of the 124 rock lobsters caught, 20.9% were in a soft shell state. Female rock lobsters constituted 43.5% of the catch, but only one was carrying eggs. Female mean tail width was 72.2 mm; male mean tail width was 71.9 mm. We found that hand collection caused significantly more injuries than snare collection, to both soft shell and hard shell animals. Hand collection also resulted in more major injuries, with 18% of hard shell animals and 31% of soft shell animals losing two or more limbs. We recommend that the prohibition on the use of rock lobster snares be lifted, as their use appears to significantly reduce injury and stress to rock lobsters in recreational dive areas, and increase the survival of undersized individuals released after capture.

title: Cadmium mobilisation by dissolved organic matter in contaminated soils amended with compost and peat

authors: Welikala, Dharshika

abstract: Some organic matter (OM) soil amendments derived from biowaste have been shown to reduce plant uptake of Cd, which presents them as an attractive option for mitigating potential health risks on some contaminated soils. However, recent studies have highlighted that dissolved organic matter (DOM) release from the amendments may increase the mobilization of metals in those soils. The provenance of the OM and the quality of the emergent DOM have been suggested as important determinants in the extent to which this occurs. However, these effects have not been systematically tested in different soil environments, where the amount of DOM released from the OM, and its affinity to form Cd-DOM complexes, may vary. Our aim in this work was to explore whether the type of OM soil amendment influences Cd mobility in contaminated soils at different pHs, and if DOM characteristics contribute
to this effect.

abstract: Nō te ūnga mai o Tainui waka, i Whangaparāoa, ka tīmata i reira te tautapa haere a Tainui waka i tōna rohe, i tāna tere i Te Ika-ā-Māui. Nāwai rā ka tau ki tōna tumu i roto o Kāwhia Moana, Kāwhia Kai, Kāwhia Tāngata, i te taha hauāuru o Te Ika-ā-Māui. I roto i ngā rautau i muri mai i te ūnga o Tainui waka me ngā tūpuna i tere mai i te waka, ka tīmata ngā tūpuna te mātoro haere i te whenua hou me te whakanoho i ngō rātou whānau. Ka tupu i koneki ngā hapū me ngā iwi i heke mai i ngā waka. I roto i ngā tātai whakapapa o Tainu waka, e mārama mai ana ngā kāwai heke ki ngā iwi o Waikato me Maniapoto hoki. Ka whai mana ngā rangatira o ngā iwi nei i ngō rātou kāinga me ngā pānga whenua i noho ai rātou.
I hua tuatahi ai te iwi o Waikato-Maniapoto i roto i ngā pakanga me ngā whakaipoipotanga mo ngā kāinga me ngā pānga whenua, kai, moana hoki. Nā ngā pūkenga wānanga, pakanga hoki, i whakawehe, i kotahi ai rānei ngā iwi.
I te taenga mai o te Pākehā ki te pēhi i ngā tikanga a te Māori, ka huri te aro o te Pākehā ki te whakahau me te whakawai i ngā rātou tauira hou ki runga i ngā iwi.
Ka whakaturengia ngā ingoa o ngā tikanga hou, nā te Kāwanatanga Pākehā hou nei i whakamana, ā, i whakaū ngēnei tikanga hou kia pēhia ngā tikanga taketake ake a te Māori. Ka huri a Waikato-Maniapoto iwi ki te aru i ngā tauira hou ki te whakawhanake i ngā uri whakatupu i roto i te ao hou. Hoi, i mau tonu i a Waikato-Maniapoto te wairua me ngā tikanga i heke iho ki ngōna uri.
Ka whakaūngia te wairua me ngā tikanga o ngā mātua tūpuna ki roto i te tauira hou o te Kīngitanga. Ka mahi ngātahi te Kīngitanga me te iwi o Waikato-Maniapoto ki te whakatinana i tōna kaupapa, arā, hei pupuru i te toto; hei pupuru i te whenua; ā, hei pupuru i te mana Māori motuhake. I roto i te Kīngitanga nga 
hanganga iwi hou i puta hei kōkiri i ngā rautaki whakawhanake i te iwi whānui i roto i te ao hou nei.
Huhua noa atu ngā uri o Waikato-Maniapoto i whai wāhi i runga i ngā tūranga whakawhanake i te iwi whānui mā te whakaū i te mana Māori motuhake i roto i te reo me ngā tikanga o Waikato-Maniapoto iwi me ngōna kaupapa. Ko te whakahua i ngā hononga iwi kia whai whanaungatanga, kia whai tūrangawaewae te whakatinanatanga o te whakapono ā-wairua nei ki ngā taonga tuku iho o Waikato-Maniapoto. Ka whai mana, ka tūturu te kīanga a Waikato-Maniapoto i roto i te whakamana a ngā uri i ngā kōrero whakapapa o te iwi o Waikato-Maniapoto me te whakamana i te kīanga nei i ngā reanga whakapapa.
