  • Succession and stability in two rocky intertidal communities on the central Oregon coast

    Creator:
    Farrell, Terence M.
    Abstract:
    The stability of a limpet-dominated community was assessed in a experiment in which an consumer was temporarily removed. Compared to unmanipulated plots, the limpet-exclusion plots developed greater algal abundance and altered species composition of both algae and barnacles. The community was not perturbed beyond its capacity to recover, since the...

  • The role of avian predators in an Oregon rocky intertidal community

    Creator:
    Marsh, Christopher P.
    Abstract:
    Birds affected the community structure of an Oregon rocky shore by preying upon mussels (Mytilus spp.) and limpets (Collisella spp.). The impact of such predation is potentially great, as mussels are the competitively dominant mid-intertidal space-occupiers, and limpets are important herbivores in this community. Prey selection by birds reflects differences...

  • A limpet kelp interaction : description and definition

    Creator:
    Yates, Kenneth R.
    Abstract:
    The interaction between the acmaeid limpet, Collisella instabilis and the subtidal laminarian, Pterygophora californica involves positive effects on the limpet population and subtle positive or null effects on the kelp. Collisella, which is found only on Pterygophora and another kelp, Laminaria dentigera (Kjellman, 1889), may exploit several features of the...

  • Prey selection by the tropical marine snail Thais melones : a study of the effects of interindividual variation and foraging experience on growth and gonad development

    Creator:
    West, Lani
    Abstract:
    I studied the feeding behavior of marked individuals of the carnivorous marine snail Thais melones in a rocky shore habitat of Pacific Panama. The population of snails consume a variety of invertebrate species such as bivalves, limpets, and polychaetes. Individuals exhibited a range of diet breadth, with some specialized, but...

  • Community organization and succession in rocky intertidal surfgrass beds

    Creator:
    Turner, Teresa
    Abstract:
    Succession and organization of rocky intertidal zone surfgrass beds (Phyllospadix scouleri Hook) were examined experimentally at two sites on the Oregon coast. The interaction of three attributes of the plant -- high persistence, high preemption, and slow recovery -- strongly influences the organization of surfgrass beds. Permanent plots indicate that...

  • The feeding ecology of the gumboot chiton, Cryptochiton stelleri (Middendorff, 1846)

    Creator:
    Yates, Kenneth R.
    Abstract:
    Investigations about the feeding ecology of a consumer can facilitate prediction of its effects on prey populations and the biological community. The aspects of feeding ecology that are important to predicting consumer effects include foraging movements, feeding preference and selectivity, and the effects of physical factors on foraging behavior and...

  • Marine herbivore-plant interactions : the feeding ecology of the sea slug Placida dendritica

    Creator:
    Trowbridge, Cynthia D.
    Abstract:
    The feeding ecology of a common temperate mesoherbivore, the oligophagous sea slug Placida dendritica (Gastropoda: Opisthobranchia: Ascoglossa), was examined from April 1985 to June 1989. Along the central coast of Oregon, Placida consumed three host species: the low intertidal green algae Codium setchellii, C. fragile, and Bryopsis corticulans. Individual slugs...

  • Acoustical localization of concealed prey by the diurnal harrier (Circus cyaneus)

    Creator:
    Rice, William Richard
    Abstract:
    I experimentally examined the adaptive significance of the anatomical and behavioral convergence between the harrier (Circus cyaneus, also refered to as the marsh hawk) and certain owls that are capable of capturing prey in total darkness. Anatomically, both the harrier and owls have evolved a sound collecting facial ruff (a...

    Creator:
    Dudley, Thomas L.
    Abstract:
    Craneflies of the genus Lipsothrix inhabit decomposing wood in streams. The life cycles and ecological relationships of L. nigrilinea (Doane) and L. fenderi Alexander were investigated to determine how they exploit and respond to the wood habitat and their role in degradation of woody debris in western Oregon. Surveys of...

  • Early succession in beds of the red alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae) : alternate pathways

    Creator:
    Olson, Annette M.
    Abstract:
    Multiple successional sequences have been observed following disturbance in communities on marine hard substrata. Observations of the turf-forming alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae), suggest that I. cornucopiae may assume its dominance by its ability to vegetatively pre-empt space. High limpet densities in the natural community, suggest that I....
