Light Limitation within Southern New Zealand Kelp Forest Communities
Light is the fundamental driver of primary productivity in the marine environment. Reduced light availability has the potential to alter the distribution, community composition, and productivity of key benthic primary producers, potentially reducing habitat and energy provision to coastal food webs. We compared the underwater light environment of macroalgal dominated shallow subtidal rocky reef...

Many New Zealand trees have flowers which are small, shallow, clustered, and lack bright colours. This un specialized floral form is suitable for pollination by small insects, such as flies and thrips. Thrips obscuratus is among the most frequent visitors ...
متن کاملForest Instability and Canopy Tree Mortality in Westland, New Zealand!
Many researchers in New Zealand have accepted equilibrium models of vegetation change that assume within-stand self-replacement of the dominant tree species as the norm. Consequently, many discontinuous stand structures have been used as evidence of forest instability. For example, the patterns of regeneration and mortality in the rata-kamahi forests of Westland have led many to believe that th...
متن کاملTherapeutic Properties of New Zealand and Australian Tea Trees
There has recently been a significant increase in the use of therapeutically active compounds extracted from plants as opposed to chemically synthesised drugs. The demand for natural products is increasing and in many cases currently exceeds supply. The flora of New Zealand and Australia is rich in unique species, however, very few of these native plants have been tested for medicinal constitue...
