Seasonal declines in the fecundity of arctic-breeding sandpipers: different tactics in two species with an invariant clutch size
The breeding biology of Western and Semipalmated Sandpipers was studied for four years near Nome, Alaska. Despite a short breeding season and a putatively invariant clutch size, there were seasonal declines in the fecundity of both sandpiper species. Most females produced only one clutch ( > 98%), but often laid fewer than four eggs (7.6-34.5% of first nests). Clutches of 2-3 eggs were initiate...
متن کاملSexual dimorphism and adaptive speciation: two sides of the same ecological coin.
Models of adaptive speciation are typically concerned with demonstrating that it is possible for ecologically driven disruptive selection to lead to the evolution of assortative mating and hence speciation. However, disruptive selection could also lead to other forms of evolutionary diversification, including ecological sexual dimorphisms. Using a model of frequency-dependent intraspecific comp...
متن کاملChronology of Nesting Events in Western and Semipal- Mated Sandpipers near the Arctic Circle
--The chronology of nesting events was examined in Western Sandpipers (Ca/idris mauri) and Semipalmated Sandpipers (C. pusilia) breeding at Nome, Alaska. The duration of laying (5 d for a 4-egg clutch) and hatching (53.0 -+ 26.6 SD h, dry chicks to emerge from star-pipped eggs) was similar for both species. Laying rates of Semipalmated Sandpipers at Nome were slower than other populations, poss...
متن کاملMolecular sexing of prey remains permits a test of sex-biased predation in a wintering population of western sandpipers.
Population sex ratios in monogamous birds are often male biased. One factor that can affect population sex ratios is sex-biased predation. However, most estimates of sex-biased predation in birds have focused on species with obvious sexual colour dimorphism or body size dimorphism. Data on sexually monomorphic birds are generally lacking. In the present study, we adopt a PCR-based sexing proced...
متن کاملLatitudinal clines in bill length and sex ratio in a migratory shorebird: a case of resource partitioning?
Sexual segregation outside the mating season is common in vertebrates. This has been shown to arise through resource partitioning in a number of taxa, but never in avian migrants. Western sandpipers (Calidris mauri) are migratory shorebirds that mainly breed in Alaska and overwinter along the coast in western and eastern North America down into South America. Females are slightly larger than ma...
