Feeding rates and prey : predator size ratios of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae
predator size Feeding rates and prey
2014/11/28
We studied the feeding behavior of the nauplii and adult females of the marine cyclopoid copepod Oithona
davisae in the laboratory. Functional response experiments showed that O. davisae can feed on ...
Researchers examining the chemical warfare taking place on Fijian coral reefs have found that one species of seaweed increases its production of noxious anti-coral compounds when placed into contact w...
Food web consequences of size-based predation and vertical migration of an invertebrate predator (Leptodora kindtii)
size-based predation an invertebrate predator
2014/4/2
In an intensive study of the vertical and horizontal distribution of zooplankton in a eutrophic lake (Katepwa
Lake), we found that only adult Leptodora kindtii (. 5 mm in body size) exhibited diel ve...
Physical factors influencing the distribution of a top predator in a subtropical oligotrophic estuary

We used longline fishing to determine the effects of distance from the ocean, season, and short-term variation in abiotic conditions on the abundance of juvenile bull sharks (Carcharhinus leucas) in a...
Food-web structure and planktonic predator–prey relationships in two eutrophic European lakes: Stability constraints on carbon fluxes
Food-web structure planktonic predator–prey relationships two eutrophic European lakes Stability constraints carbon fluxes
2014/4/21
The food webs in two eutrophic European lakes were analyzed with respect totheir stability characteristics.The food web during the summer in Lake Nesjøvatn (Norway) appeared to be stable; its res...
Body temperature during low tide alters the feeding performance of a top intertidal predator
Body temperature low tide alters feeding performance intertidal predator
2014/4/18
Although the direct effects of climate change on species distribution andabundance have become increasingly apparent, considerably less is known about the potential for thermal variations to influence...
The effects of temperature and predator-prey interactions on the migration behavior and vertical distribution of Mysis relicta
temperature predator-prey migration behavior vertical distribution Mysis relicta
2014/4/22
The extent to which temperature, temperature gradients, predator smell, and prey availability influence the migratory behaviors and vertical distribution of the opossum shrimp, Mysis relicta, was expl...
Individual foraging behaviors and population distributions of a planktonic predator aggregating to phytoplankton thin layers
Individual foraging behaviors population distributions
2014/4/23
Resource distributions in the ocean are heterogeneous in time and space. Theory predicts planktonic predators
may exploit these resource patches by modifying their movements in response to mechanical...
Effect of turbulence on sedimentation and net population growth of the dinoflagellate Ceratium tripos and interactions with its predator, Fragilidium subglobosum
Effect of turbulence on sedimentation and net population growth of the dinoflagellate Ceratium tripos and interactions with its predator, Fragilidium subglobosum
2014/5/13
We investigated the effect of natural levels of turbulence on the vertical distribution and net population growth of the dinoflagellate Ceratium tripos and on the interaction with its predator, the mi...
A behavioral cascade: Top-predator induced behavioral shifts in planktivorous fish and zooplankton
Top-predator planktivorous fish zooplankton
2014/5/21
It is well known that the effects of direct (lethal) predator-prey interactions propagate through food webs (the trophic cascade). However, in the present study we show for the first time that, parall...
Cryptic coloration and mirrored sides as camouflage strategies in near-surface pelagic habitats: Implications for foraging and predator avoidance
mirrored sides camouflage strategies near-surface pelagic habitats foraging and predator avoidance
2014/5/20
Mirrored and colored surfaces are common adaptations for crypsis in pelagic habitats. Although highly successful when optimized for a particular situation, either may become less successful if it is t...
