Rockfish response to low-frequency ocean climate change as revealed by the diet of a marine bird over multiple time scales (2004, methodology): “Sydeman et al. (2001) summarized annual diet composition of Southeast Farallon Island murres through 1997 based on total numbers of identified prey items (n = 164 to 3975 items yr–1).”
Top-down and bottom-up factors affecting seabird population trends in the California current system (1985-2006) (2010, background): “The documented decrease in the western gull at-sea population, consistent with a long-term decrease in their reproductive output (Sydeman et al., 2001) and their Farallon breeding population (Warzybok and Bradley, 2007), can also be attributed to the declining prey availability mentioned above.”
Winter and summer upwelling modes and their biological importance in the California Current Ecosystem (2011, background): “…of breeding and breeding success have been monitored at Southeast Farallon Island ( 48 km west of San Francisco Bay; 37.71N, 123.01W) by Point Reyes Bird Observatory under contract with the US Fish and Wildlife Service since 1971 (Ainley et al., 1995; Sydeman et al., 2001; Schroeder et al., 2009).”
Ecosystem-based fisheries management: some practical suggestions (2007, background): “The impact of the loss of forage species is then evidenced by increased seabird mortality (Ainley et al. 1995; Sydeman et al. 2001 ).”
Effect of environmental variability on habitat selection, diet, provisioning behaviour and chick growth in yellow-nosed albatrosses (2005, background): “This shows that, when prey availability is lower in the vicinity of breeding sites, top-predators change their foraging and forage further to exploit distant resources, although very low breeding success can be observed during these conditions (Sydeman et al. 2001).”
Diets of top predators indicate pelagic juvenile rockfish (Sebastes spp.) abundance in the California Current System (2007, background): “, 1999), marine birds (Ainley et al., 1995; Sydeman et al., 2001; Miller and Sydeman, 2004), and mammals (Pike, 1958; Lowry et al.”
Foraging distance affects reproductive success in Magellanic penguins (2009, background): “Interannual changes in prey distribution or availability may also cause foraging-trip distance to vary (Boyd et al. 1994, Sydeman et al. 2001, Inchausti et al. 2003).”
Marine bird and cetacean associations with bathymetric habitats and shallow-water topographies: impl (2004, background): “In 1996 and 1997, murres provisioned offspring primarily on northern anchovies (Sydeman et al., 2001), whereas in 2001 and 2002, pelagic juvenile rockfish had become more prevalent in the diet (Mills et al., submitted for publication).”
Black-legged kittiwakes as indicators of environmental change in the North Sea: Evidence from long-term studies (2007, background): “The low quality, in terms of size and lipid content, of sandlance recorded in 2004 (Harris et al., 2005; Wanless et al., 2005) is indicative of exceptionally poor feeding conditions for sandlance and hence of changes in lower trophic levels.”
Planktivorous auklet Ptychoramphus aleuticus responses to ocean climate, 2005: Unusual atmospheric blocking? (2006, background): “Off northern California, 35 years of information on the productivity (breeding success) and food habits of marine birds is available from SE Farallon Island (SEFI) [Sydeman et al., 2001].”
Linking predators to seasonality of upwelling: Using food web indicators and path analysis to infer trophic connections (2012, methodology): “Methods to determine reproductive success and timing of breeding (mean egg laying date) are provided by Ainley et al. (1995) and Sydeman et al. (2001, 2009).”
Low energy values of fish as a probable cause of a major seabird breeding failure in the North Sea (2005, background): “However, such events do occur regularly in the Pacific where they have been linked to climate variability impacting on prey abundance cascading through to upper trophic levels (Sydeman et al. 2001).”
Ocean climate, euphausiids and auklet nesting: inter-annual trends and variation in phenology, diet and growth of a planktivorous seabird, Ptychoramphus aleuticus (2004, methodology): “…spinifera (class Crustacea) are the principal prey of the Farallon Islands population of Cassin’s auklet Ptychoramphus aleuticus, planktivorous marine birds of the California Current ecosystem (Manuwal 1974, Ainley & Boekelheide 1990, Ainley et al. 1990, 1996, Sydeman et al. 1997, 2001).”
