| AFLP | Amplified Fragment Length Polymorphism is a relatively new multi-locus DNA profiling technique which provides information on many different loci in a single assay. It is a powerful means of 'finger-printing' individual clones as well as establishing genetic distances and the relationships among clones based on genetic similarities. |
| dioecious | applied to organisms in which male and female reproductive organs are borne on different individuals as opposed to the same individual. |
| GIS | Geographical Information System - this is a data management system which involves collating, storing, integrating, analysing and displaying data which are spatially referenced to a fixed point (e.g. the earth). |
| HEP | HydroElectric Power |
| HPLC | High Performance Liquid Chromatography |
| Instream Flow Incremental Methodology (IFIM) | a set of techniques that assesses flow patterns in a representative stream reach and attempts to correlate these patterns with the minimum flow requirements and hydrological preferences of target aquatic species. |
| mycorrhizae | these are soil fungi which colonise the roots of most plants. They form a mutualistic association with the host plant by increasing the surface area for absorption of nutrients and in return receive carbohydrates derived from photosynthesis. |
| piezometer | a piezometer measures infiltration rates as controlled by the vertical conductivity of soils. |
| PHABSIM | Physical HABitat SIMulation is a methodology, or set of sub-routines which integrates hydraulic and biological information to predict available habitat for target species over a range of discharges. |
| rhizopod | an apparatus (after Mahoney & Rood, 1991) which allows for the simulation of alluvial groundwater fluctuations and declines. Each rhizopod is constructed from 1.2 m sections of PVC tubes and consists of 16 growth tubes (diameter of 10 cm) connected by tubing at the base to a central water well, or reservoir. A top at the base of the water well allows for the manipulation of water table levels in the growth tubes. |
| rhizotron | an apparatus designed to monitor root development under a range of soil-moisture conditions. Each rhizotron is constructed of transparent perspex sheets to form a box (1m x 1m and 5cm wide), fitted with a drain at the bottom. When inclined at a 45º angle the roots of experimental plants are displayed along the surface of the perspex sheet. |
| riparian | land bordering a river; riverside. |
| river corridor | a continuous strip of land (interface area) between the stream channel and surrounding landscape, also referred to as a buffer strip, or riparian zone. |
| Salicaceae | willows (Salix) and poplars (Populus) make up this family of early successional, dioecious woody riparian tree species. Willows and poplars are strikingly well adjusted to the environmental extremes and disturbance regimes encountered in the active channel of natural floodplains. They are characterized by rapid growth and an inherent freedom of hybridisation. |
| tensiometer | an instrument that measures soil-suction (hPa) by sensing the pressure change in an enclosed column of water. |
