title: Carbon in soils

authors: Schipper, Louis A.

subjects: carbon

abstract: Carbon is the fourth most common element in the galaxy(by mass) but does not even rank in the twelve most abundant elements on Earth. By far the most abundant source of carbon on Earth is in the crust as inorganic rocks such as calcite and limestone in marine and sedimentary deposits. These rocks have taken many millions of years to form. Other major inorganic sources are in the oceans and atmosphere.

title: Multiple stressor effects on marine infauna: responses of estuarine taxa and functional traits to sedimentation, nutrient and metal loading

authors: Ellis, Joanne I.

subjects: Science & Technology

abstract: Sedimentation, nutrients and metal loading to coastal environments are increasing, associated with urbanization and global warming, hence there is a growing need to predict ecological responses to such change. Using a regression technique we predicted how maximum abundance of 20 macrobenthic taxa and 22 functional traits separately and interactively responded to these key stressors. The abundance of most taxa declined in response to sedimentation and metal loading while a unimodal response was often associated with nutrient loading. Optimum abundances for both taxa and traits occurred at relatively low stressor levels, highlighting the vulnerability of estuaries to increasing stressor loads. Individual taxa were more susceptible to stress than traits, suggesting that functional traits may be less sensitive for detecting changes in ecosystem health. Multiplicative effects were more common than additive interactions. The observed sensitivity of most taxa to increasing sedimentation and metal loading and the documented interaction effects between multiple stressors have important implications for understanding and managing the ecological consequences of eutrophication, sedimentation and contaminants on coastal ecosystems.

title: Te matakite - Te kupu whakaari

authors: Temara, Pou

subjects: Matakite

abstract: Ko te whāinga o tēnei tuhinga poto he matapaki i te matakite me te kupu whakaari, arā, he whakatakoto i tētahi tūāpapa kōrero e mārama ai te kaipānui ki te tikanga o ēnei kaupapa e rua e ai ki tā te Māori i matapaki ai. Otirā, he kōrero tā ngā iwi katoa o te ao mō te matakite me te kupu whakaari, kai tēnā iwi tāna kōrero, kai tēnā iwi tāna. Kāore tēnei tuhinga e rere ki te whakamārama i ā ētahi kōrero, engari mau tonu ki te ao Māori. Mēnā ka whakahua i ngā whakamārama a ētahi atu iwi, e whai ana kia mārama ai te tauira ki tā te Māori i kōrero ai.
