The heath land vegetation of northern New Zealand is usually regarded as a "derived" vegetation type resulting from forest destruction during the Maori and European periods of settlement. Plant species coverabundance data from sample quadrats in the Far North are analysed using Detrended Correspondence Analysis (DCA) and Two-way Indicator Species Analysis (TWINSPAN) and are then correlated with...

Ecosystem disturbances that remove vegetation and disturb surface soils are major causes of excessive soil erosion and can result in accelerated transport of soils contaminated with hazardous materials. Accelerated wind erosion in disturbed lands that are contaminated is of particular concern because of potential increased inhalation exposure, yet measurements regarding these relationships are ...

This study was undertaken to quantify the nutrient turnover and soil fertility status in the natural forests of Central Western Ghats. Major nutrients such as nitrogen, phosphorus and potassium were analyzed in the litter, both from the samples collected in pre and post monsoon seasons. There was no much difference seen in the values between the two seasons studied in all the three nutrients st...

Soil water repellency (SWR) was studied in 64 surface soil samples from Tenerife (Canary Islands, Spain), distributed over three different plant communities (natural and afforested Canarian pine forest, and high mountain legume scrub) and three types of soil parent materials (basaltic and salic rocks and basaltic tephra). Soils were studied for physicochemical properties (soil pH and salinity, ...

(The survival and establishment potential of spores of Cyathea delgadii Sternb. in soils from Itirapina and Moji Guaçu (SP), Brazil). Germination of spores of Cyathea delgadii was carried out in soils collected in March 1997 (rainy season) at three depths (0-5, 5-10 and 10-15 cm) from the cerrado, open-cerrado, gallery forest and marsh at Moji Guaçu and cerradão, cerrado and gallery forest at P...

Resource pulses are occasional events of ephemeral resource superabundance that occur in many ecosystems. Aboveground consumers in diverse communities often respond strongly to resource pulses, but few studies have investigated the belowground consequences of resource pulses in natural ecosystems. This study shows that resource pulses of 17-year periodical cicadas (Magicicada spp.) directly inc...
