“…As guano contains considerable amounts of marine‐derived N, stable isotope analyses can be applied to materials (e.g. soil, vegetation, invertebrates; Hawke & Clark, 2010) from within and outside seabird colonies to trace the flow of nutrients from the guano, and have been used successfully to determine the presence of seabirds in areas where colonies are no longer present (Kameda et al, 2006).…”

“…They are thus frequently involved in cross-habitat subsidies of energy and nutrients between strictly aquatic and terrestrial systems. Waterbird breeding colonies in forests provide major subsidies through their faeces (Kameda et al, 2006). Such reciprocal subsidies are as yet poorly understood and are currently subject to growing research (Baxter et al, 2004;Burdon & Harding, 2008).…”

Ecosystem services provided by waterbirds

Ecosystem services are ecosystem processes that directly or indirectly benefit human well-being. There has been much recent literature identifying different services and the communities and species that provide them. This is a vital first step towards management and maintenance of these services. In this review, we specifically address the waterbirds, which play key functional roles in many aquatic ecosystems, including as predators, herbivores and vectors of seeds, invertebrates and nutrients, although these roles have often been overlooked. Waterbirds can maintain the diversity of other organisms, control pests, be effective bioindicators of ecological conditions, and act as sentinels of potential disease outbreaks. They also provide important provisioning (meat, feathers, eggs, etc.) and cultural services to both indigenous and westernized societies. We identify key gaps in the understanding of ecosystem services provided by waterbirds and areas for future research required to clarify their functional role in ecosystems and the services they provide. We consider how the economic value of these services could be calculated, giving some examples. Such valuation will provide powerful arguments for waterbird conservation.

“…One possible source of heavy nitrogen prehistorically is waste from large numbers of waterfowl, which can make major contributions of nutrients to lakes (Gould and Fletcher, 1978) especially during migration (Manny et al, 1994). Reported δ 15 N values in the literature from fresh waterfowl excreta -mainly from seabirds -are isotopically heavy: gulls 9.4‰ Wada, 1988), 9.2‰ (Mizutani et al, 1985a); penguins 6.2‰ (Mizutani et al, 1985b), 8.0‰ (Mizutani and Wada, 1988), 14.6‰ (Erskine et al, 1998); cormorants 13.2‰ (Kameda et al, 2006); and various seabirds 9.9‰ (Schmidt et al, 2004). These values range from 6.2‰ to 14.6‰ and are mainly from piscivorsous birds with high trophic status.…”

Episodic struvite deposits in a Northern Great Plains flyway lake: indicators of mid-Holocene drought?

A series of 34 layers of struvite (hydrous Mg-ammonium-phosphate) were deposited in laminated sediments of Kettle Lake, North Dakota, in the Northern Great Plains, USA. Sedimentologic, mineralogic and nitrogen isotopic evidence suggest that struvite was deposited during nutrient-enriched eutrophication events within a Mg-rich lacustrine environment. The struvite layers are dispersed between 4650 and 8700 cal. yr BP, with particularly high frequency between 8068 and 8700 cal. yr BP. The youngest struvite layer dates to 2734 cal. yr BP. Key features of the struvite-forming events were (a) relatively low water stage and consequent elevated water salinity associated with the dry mid Holocene, (b) disappearance of most lakes and wetlands in the region, and (c) focused, but brief, visitations by large populations of migratory waterfowl. The lack of more frequent occurrence of struvite is ascribed to the rarity with which this combination of conditions was achieved, in combination with difficulty of preservation for this salt. 15N isotopes in struvite (mean 7.51‰) are heavy relative to 15N in sediment and also extremely uniform over time. The isotopes are interpreted to reflect a waterfowl waste source without extensive NH4 volatilizaton. The timing of the struvite events does not closely correspond to century-scale mid-Holocene drought cycles inferred from oscillating aragonite concentrations, although there is a weak preferred occurrence in the humid phase of these cycles. Thus the struvite events are ephemeral prairie features of this generally arid period but tend not to occur at precisely the most arid intervals.
