LABARBERA, M. : Physical constraints in scallop swimming: take-off and swimming mechanics Take-off from the substrate and swimming were recorded for the cold-temperate scallops Chlamys hastata (N=10), C. rubida (N=22), and Crassodoma gigantea (N=7) and the warm-temperate Argopecten irradians (N=43) using high speed video. The Chlamys species and Argopecten swim throughout their lives, but Crassodoma […]

Thomas, F.I.M.; Bolton, T.F.: Mechanical forces imposed on echinoid eggs during spawning: mitigation of force by fibrous networks within egg extracellular layers Eggs of echinoids are exposed to mechanical forces during spawning. The magnitude of these forces depends on the properties of the eggs and the relative dimensions of the egg and gonopores. Recent evidence […]

MOORE,A.M.F.*; CHIU,H.; LAWRENCE,B.A.: Mechanical Characterization of Egg Case Silk in the Black Widow Spider (Latrodectus hesperus) Silk from egg case of the black widow spider (Latrodectus hesperus) differs in amino acid composition from the animal’s dragline silk. Because the primary function of an egg case is non-load bearing, we expected that the molecular differences in […]

SHERRARD, K.M.: Limits to early juvenile suspension feeding performance in sea squirts Post-metamorphic marine invertebrates are maximally different from adults in size, though often similar to them in morphology and behavior. How does small size affect early juvenile performance? Ascidians, as sessile suspension feeders, provide a convenient system in which to investigate this question. In […]

PRATT, M.C.: Growth and survival of an erect and encrusting bryozoan in different flow habitats Bryozoans are active filter feeding invertebrates that can exhibit a wide variety of different colonial growth forms. These growth forms can roughly be divided into species that are erect or encrusting. I compared the effects of hydrodynamics on the growth […]

Koehl, M.* A. R. *; Hadfield, M.G.; Cooper, T.; Reidenbach, M.A.; Koseff, J.R.: Can Larvae of Benthic Animals Use Dissolved Chemical Cues in Wave-Driven Flow? Can chemical cues in the water affect the settlement of larvae of benthic marine invertebrates in habitats subjected to the wave-driven water flow that characterizes many coastal habitats? We addressed […]

SCHANK, Jeffrey: Is Pseudoreplication a Pseudoproblem? In 1984, Stuart Hurlbert introduced the problem of pseudoreplication as serious and ubiquitous problem in ecological research design. Since then, the view that pseudoreplication is a serious research problem has spread to other fields including animal behavior. Pseudoreplication is best characterized as having two main concerns. First, the relationship […]

ROGOWITZ, G. L.: Influences of age and reproductive status on locomotor performance of mice. I tested whether the locomotor performance and aerobic capacity of the white-footed mouse (Peromyscus leucopus) change with age during postnatal development or with reproductive status (pregnancy and lactation). Either could have ecological or evolutionary consequences because locomotor performance can affect predation […]

JOHNSEN, S: Hidden in plain sight: cryptic and conspicuous coloration in the pelagic environment Despite the importance of cryptic and conspicuous coloration in pelagic ecosystems, few researchers have investigated the optimal reflectance spectra for either trait. In this study, the underwater radiance distribution in tropical oceanic water was modeled using measured inherent optical properties and […]

FINGERUT, J.T.; ZIMMER, C.A.; ZIMMER, R.K.: From host to host: interaction of behavior and the environment during parasite transmission Parasites that transmit infection between hosts through free-swimming larval stages must interact both with the host’s internal environment and external habitat. The trematode Himasthla rhigedana moves from its 1st to 2nd intermediary hosts as a free-swimming […]
