“…Alterations to land use have many effects on streams, including changes to water temperature (Quinn et al 1992(Quinn et al , 1997Rutherford et al 1997), sediment loading (Allan etal. 1997), community composition of both invertebrates (Harding & Winterbourn 1995;Collier et al 1997) and fish (Hanchet 1990). In particular, pasture streams can be expected to have greater autochthonous production than native bush streams, because of the absence of shading and smaller inputs of allochthonous detritus in the former, with consequences for aquatic food chains (Bird & Kaushik 1992).…”

Crayfish (Paranephrops zealandicus White) stomachs from streams in both native bush (mainly tree leaves and dicotyledonous seeds) and exotic pasture settings (mainly grass stems and monocotyledonous seeds) were dominated by allochthonous material. More detritus occurred in stomachs in autumn-winter than in spring-summer, but quantities were similar in crayfish from native bush and pasture streams. The stomachs of larger crayfish contained a significantly greater proportion of detritus than smaller individuals. Aquatic invertebrates were the second most abundant dietary category by volume, with highest values in winter, but there were no significant differences between land uses or crayfish size classes. A wide range of invertebrates was eaten by crayfish, with mayfly nymphs, chironomid larvae, and snails predominating. The latter were numerically more prominent in crayfish from bush than pasture streams. Terrestrial invertebrates were recorded from 4% of stomachs, but there were no significant differences in relation to land use, season, or crayfish size class.

“…Focusing attention on the adult phase of the life cycle has highlighted the importance of the structure of the terrestrial habitat for mating, resting and egg maturation (Kovats et al, 1996) and for entry into terrestrial food webs (Svensson, 1974;Jackson and Resh, 1989;Ormerod and Tyler, 1991). Adult trapping integrates catches from a wider range of aquatic habitats and reflects corridor land-use and, consequently, can be used as a useful tool for bioassessment (Collier et al, 1997). This study shows how the collection of adult Trichoptera using non-attracting Malaise traps can provide the necessary data on community structure and taxonomic rigour, to assess the conservation status of small streams.…”

“…There have been some important papers on small streams (e.g. Williams et al, 1992), but until recently there was little information about adults in small streams (Svensson, 1974;Collier et al, 1997;Collier and Smith, 1998;Griffith et al, 1998;Petersen, et al, 1999).…”

ABSTRACT1. Adult caddisflies were collected using non-attracting Malaise traps at four sites on a small headwater stream from May to November 1990. Sites S1 and S2 were most natural and upstream of a reservoir; where S3 was located in the bypass channel, and S4, downstream.2. The flight period for each species is recorded to provide baseline data. Flight activity patterns fall into two groupings: (a) species with a flight activity of 3 -4 months, and (b) those species with a short flight period of up to 6 weeks.3. Sixty-one species from 15 families were collected, including the endangered Red Data Book species Tinodes pallidulus McLachlan.4. Significant differences in community parameters are shown among all sites, many species apparently having local catchment areas. The influence of artificial habitats, the open bypass channel and adjacent reservoir, is clearly demonstrated.5. The data illustrate the potential of using adult caddisflies in conservation assessment of small streams. Working with adults is taxonomically rigorous and they are useful bioindicators of the environmental quality of the valley floor corridor.

“…It led to the development of a conceptual model for the effects of land-use change on hyporheic habitat, the testing of which is the subject of current studies at Whatawhata. Collier et al (1997) demonstrated strong landuse influences on adult caddisfly faunas. As with the benthic faunas (Quinn et al 1997a), the composition of adult caddisfly faunas differed most between the native forest and pasture sites with pine forest sites intermediate between these.…”

A programme of research is introduced on the effects on stream ecosystems of land-use change from native forest to pasture, and subsequent re-afforestation with exotic pine plantations. The results detailed in the 11 accompanying papers conclude that land-use change has had strong effects on many key physical, chemical, and biological aspects of stream ecosystems in and adjacent to Whatawhata Research Centre, near Hamilton, New Zealand. Six of these papers compare streams, draining catchments with similar topography, geology, and soils, to investigate land-use effects on stream lighting, water quality, channel morphology, benthic and hyporheic habitat and faunas, fish, and food webs. Two papers investigate hypotheses on the influence of shade and crayfish using streamside mesocosms. Finally, three papers use the experimental sites to evaluate methods for studying crayfish populations, stream carbon pathways, and a stream temperature model. These studies provide a comprehensive description of land-use effects on physical, chemical, and biological characteristics of streams and contribute to the basis for future long-term ecological research on the effects on streams of sustainable land management practices.
