    Prothonotary warbler nestling growth and condition inresponse to variation in aquatic and terrestrial preyavailability

    Aquatic prey subsidies entering terrestrial habitats are well documented, but little is known about the degree to which these resources provide fitness benefits to riparian consumers. Riparian species take advantage of seasonal pulses of both terrestrial and aquatic prey, although aquatic resources are often over-looked in studies of how diet influences the reproductive ecology of these organisms. Ideally, the timing of resource pulses should occur at the time of highest reproductive demand. This study investigates the availability of aquatic(mayfly) and terrestrial (caterpillar) prey resources as well as the nestling diet of the prothonotary warbler (Protonotaria citrea) at two sites along the lower James River in Virginia during the 2014 breeding season. We found large differences in availability of prey items between the two sites, with one having significantly higher mayfly availability. Nestling diet was generally reflective of prey availability, and nestlings had faster mean growth rates at the site with higher aquatic prey availability. Terrestrial prey were fed more readily at the site with lower aquatic prey availability, and at this site, nestlings fed mayflies had higher mean growth rates than nestlings fed only terrestrial prey. Our results suggest that aquatic subsidies are an important resource for nestling birds and are crucial to understanding the breeding ecology of riparian species

    Background Acoustics in Terrestrial Ecology

    Get PDF
    The way in which terrestrial organisms use the acoustic realm is fundamentally important and shapes behavior, populations, and communities, but how background acoustics, or noise, influence the patterns and processes in ecology is still relatively understudied. In this review, we summarize how background acoustics have traditionally been studied from the signaling perspective, discuss what is known from a receiver\u27s perspective, and explore what is known about population- and community-level responses to noise. We suggest that there are major gaps linking animal physiology and behavior in noise to fitness; that there is a limited understanding of variation in hearing within and across species, especially in the context of real-world acoustic conditions; and that many puzzling responses to noise could be clarified with a community-level lens that considers indirect effects. Failing to consider variation in acoustic conditions, and the many ways organisms use and interact via this environmental dimension, risks a limited understanding of natural systems

    Book Review: Quantitative ecology and marine biology, by G J Bakus

    Get PDF
    In recent years, approach to marine community ecology has become empirical and conceptual. Terrestrial plant ecologists were the pioneers in the field of quantitative ecology and the application of their models in marine ecosystem analyses has thrown open a vast new field of interest to those marine biologists who are mathematically oriented

    Studies on the succession of marine algae on a fresh substratum in Palk Bay

    Get PDF
    Despite the; numerous investigations on the ecology of marine plants, the subject has not advanced as much as the ecology of terrestrial plants, because, unlike the study of land vegetation, field experiments are more difficult in marine environments. In this connection, the studies of Gail (1918, 1922), of Hatton (1938) and of Rees (1940) indicate the possibility and essentiality of such experimental studie

    Ecosystem exploitation, sustainability and biodiversity: Are they compatible?

    Get PDF
    This articles offers a basis for describing sustainability and then seeks to place this concept on an energetic basis by reference to recent advances in the understanding of patterns and processes in (mainly pelagic) fresh waters. Finally, by relating these to terrestrial ecosystems, it is shown how their sustainability may be attained through encouraging healthy fresh waters. Features of population succession are taken from observations on phytoplankton ecology
