“…The dipper and the grey wagtail are the two species most frequently investigated in Europe as possible biological indicators of stream quality (Ormerod and Tyler, 1987;Logie, 1995). The results of this study confirm that the presence of the dipper is an index of good stream quality (Ormerod and Tyler, 1987;Vickery, 1991).…”

1. Riparian birds and macroinvertebrates were studied in five reaches of four tributaries of the Tiber river (Italy). The first aim was to check if stream quality, assessed by extended biotic index (EBI) values, could represent change in the riparian zone, assessed through the bird community. The second was to consider whether stream quality affects the presence of riverine bird species.2. Stream quality and richness of the riparian bird community were related. In streams with more disturbed macroinvertebrate communities, but also in agricultural areas, the relative frequency of granivorous species increased in the riparian zone.3. Dippers Cinclus cinclus occurred exclusively in reaches with the best stream quality, but the relationship between grey wagtails Motacilla cinerea and stream quality was less clear.4. These results support the judicious use of riverine and riparian birds as biological indicators.1. Farfa river (altitude 250 -300 m above sea level), characterized by modest human impact (Figure 2).

“…It is furthermore clear from our results, as well as from a number of studies carried out elsewhere, that acidified conifer forest streams provide particularly unfavourable conditions for the stream biota. This could have serious implications for the biological diversity and structure of these forest systems, as the stream invertebrates and adults of aquatic insects are an important part of aquatic and terrestrial food webs (Ormerod & Tyler, 1986; Logie, 1995).…”

1. Growth and emergence of the acidification tolerant stonefly Leuctra nigra were studied in four coniferous forest streams with contrasting pH. Invertebrate samples were taken bimonthly during May 1997 to April 1998. Emerging L. nigra were captured in two of the streams during April to July 1998 using pyramidal emergence traps. In addition, a laboratory experiment was conducted to evaluate growth of L. nigra in response to variations in food quality (neutral or acid conditioned leaves) and water pH. 2. The invertebrate community in low pH streams had lower diversity and density compared with neutral streams. Abundance of L. nigra was also lower, despite the dominance of this stonefly in the invertebrate community in the acidic streams. 3. Secondary production of L. nigra was 2.04 and 3.07 g DW m–2 year–1 in the neutral streams compared with 1.02 and 1.27 g DW m–2 year–1 in the acidic streams. The P/B ratio differed only slightly among streams. 4. More adult L. nigra emerged in the neutral stream compared with the acidic stream, despite the density of the pre‐emerging fifth instar nymphs of L. nigra being similar in the two streams. Adult size (expressed as wing length) and female fitness were also significantly greater in the neutral stream. 5. Laboratory growth of L. nigra nymphs was significantly lower when fed acid conditioned alder leaves rather than neutral conditioned leaves. There was no difference in growth when nymphs were fed neutral conditioned leaves in acid and neutral water. 6. Our study shows multiple, sub‐lethal effects on life history of the acidification tolerant stonefly L. nigra in coniferous streams with low pH. The results suggest that these effects could be mediated primarily by low food quality. These findings add to the existing evidence that coniferous plantation forestry has a negative impact on stream ecosystems.

“…Daily river flow rates (m 3 s −1 ) were provided by the Forth River Purification Board, for stations on the Rivers Devon, Allan and Ardoch. The pH for the Devon, Allan and Ardoch rivers averaged 6.5 (Forth River Purification Board, Logie 1995), confirming the circumneutral status of the habitat (Ormerod et al . 1991).…”

Variable energetic responses to clutch size manipulations in white‐throated dippers Cinclus cinclus

We used the doubly‐labelled water technique to measure daily energy expenditure (DEE) of a free‐living uniparental incubator, the white‐throated dipper Cinclus cinclus, in Scotland. DEE was 205±8 (s.e.m.) kJ d−1 for 17 females incubating their natural clutch sizes, equivalent to 3.2±0.1×basal metabolic rate (BMR). To investigate the influence of clutch size on the energy budget, we measured the DEE of 14 females with clutches increased or reduced by a single egg. Birds with reduced clutch sizes had an energy expenditure with a mean and variance that did not differ from those of birds with unmanipulated clutches. Enlarging the clutch led to an increase in energy expenditure to over 4×BMR for some individuals but not for others, resulting in greater variance in energy expenditure for birds with enlarged clutches. Individual variation in energy expenditure could not be fully explained by environmental conditions, by patterns of behaviour or clutch size.  Incubating females received a maximum of only 4 kJ d−1 (2% of DEE) from provisioning by the male, and mobilised up to 6 kJ d−1 (3% of DEE) from reserves. Females spent 2.9±0.2 h (n=20) away from the nest each day, so a foraging rate of 95 kJ h−1 was required during incubation recesses to balance DEE. This ‘required foraging rate’ is double previous estimates of the maximum rates of energy acquisition for birds of this size. We suggest that the greater likelihood of a raised energy expenditure associated with larger clutches, combined with the difficulties in maintaining energy supplies, may constitute a constraint on avian clutch size.
