Studies on the aerobic bacterial flora of a New Zealand tussock grassland soil
The work described herein was best divided into 4 rather distinct parts. All are concerned with the aerobic bacterial flora of a single New Zealand grassland soil whose characteristics are described. The 4 parts deal respectively with the characterisation of the aerobic heterotrophic bacterial …

Soil phosphatases: factors affecting enzyme activity in Arctic tussock tundra and Virginia mineral soils
The effect of pH, temperature, substrate concentration, and orthophosphate on abiontic phosphomonoesterase activity was examined in disturbed and undisturbed Arctic soils with variable moisture content and in Virginia forest, grassland and agricultural soils. Distribution of acid and alkaline …

The autecology of Stipa Trichotoma Nees (Nassella Tussock) on Rhodes Estate, in the South-Western Cape
… autecology of Stipa trichotoma Nees (nassella tussock) was studied in the Mediterranean-type climate of the south-western Cape. The study site was Rhodes Estate, on the lower slopes of Devil •s Peak. The relative growth rate of tussocks in the field was studied using nondestructive methods …

A Method for replacing serrated tussock (Nassella trichotoma) with kangaroo grass (Themeda triandra) in lowland native grassland remnants
… which replaces the noxious weed serrated tussock (Nassella trichotoma (Nees) Arech.) with indigenous kangaroo grass (Themeda triandra Forrsk.) in partly disturbed remnants of western (basalt) plains indigenous grassland, a community listed as vulnerable to extinction. Investigations were …

Factors associated with Atlantic white -cedar seedling recruitment on microtopographic and landscape scales, Brown Mill Pond, Rye, New Hampshire
… seedlings were (1) absent from hummocks with tussock sedge substrate and present on hummocks with moss or litter substrate, (2) most frequent 10--25 cm above the July water table, at "intermediate" elevations, and were less common between 25--60 cm on these hummocks.</p><p>Several multi-factor …

The role of acid phosphatases in the phosphorus nutrition of arctic tundra plants
… of Eriophorum vagina tum, a dominant plant in tussock tundra ecosystems, with its predominantly non-mycorrhizal root system; and that of ectomycorrhizal roots. Eriophorum has phosphatase activity which is evenly distributed along its root surface, has a pH optimum at soil pH (3.5-4.0), and …

The effect of grassland shifts on the avifauna of a South African savanna
… short stoloniferous grazing lawns and tall, tussock-like 'bunch' grasslands. Grazing lawns are maintained by grazing mammals, among which White Rhinoceros Ceratotherium simum is of major importance. By contrast, tall bunch grasslands are promoted by frequent burning. The extent of each …

Tracing carbon flows through Arctic and alpine watersheds
… soils colonized by Eriophorum vaginatum—a tussock-forming sedge—and Betula nana—a competitive dwarf shrub—with glucose, and employed stable isotope tracing to quantify substrate conversion to CO2, incorporation in microbial biomass, and retention in bulk soil. We measured responses during …

Gut content analysis of trapped mustelids and trend analysis for ship rats and stoats over six trapping seasons at Mount Taranaki : A thesis submitted in partial fulfilment of the requirements for the degree of Master of Natural Resource Management and Ecological Engineering at Lincoln University
… the highest frequency of stoat captures was tall tussock grassland. The habitat type with the highest frequency of ship rat captures was broadleaved indigenous hardwoods. Overall, rodents were the main food source for stoats and weasels and invertebrates were the main food source for ferrets …

Lucerne establishment studies on two types of uncultivated country : a thesis submitted in partial fulfilment of the requirements for the degree of Master of Agricultural Science with Honours in the University of Canterbury, Lincoln College
… Zealand there are more than ten million acres of tussock and danthonia grassland. Many research workers and farmers have shown that much of this area can be greatly improved by the introduction of clovers. However in the semi-arid (<20” rainfall) and parts of the sub-humid (20-40” rainfall) area …

Sedge/Grass Meadow Restoration on Former Agricultural Land: Analysis of Establishment Success
… bluejoint grass (Calamagrostis canadensis) and tussock sedge (Carex stricta), were purchased, cold-stratified, and sown with shoulder-broadcast seed spreaders in June 2010 in the study site planted areas. Plugs of Canada bluejoint grass and tussock sedge were also hand-planted in the same areas. …

Investigation of the relationships between biomass reduction, soil disturbance, soil nutrients and weed invasion in basalt plains native grassland remnants in Victoria, Australia
… to prevent the dominant native perennial tussock grasses from over shadowing the diversity of forbs that grow between the tussocks, but the effects of various biomass reduction methods on weediness, and the underlying causes of weediness, have not been studied in any depth. The outcomes of …

Patterns of energy flow in populations of the dominant insect consumers on Marion Island
… E. halticella is a host-specific folivore of the tussock grass Poa cookii, and dominates the herbivore guild on the island, while E. similis and E. marioni are polyphagous feeders of both angiosperms and bryophytes. P. marioni is a polyphagous detritivore and an important decomposer of plant …
