Seasonal trend in burrow depth and tidal variation in feeding activity of Nereis diversicolor
Ragworms Nereis diversicolor live in burrows which, if deeper than 5 to 10 cm, offer a safe refuge from most of their predators. Burrow depth must be ca 15 cm before they live out of reach of all predators. Burrow depth increases with body slze, levelling off at ca 15 cm, when the depth refuge is reached. Worms live at greater depths in sand than In mud, but this effect disappears if worms with...
متن کاملEstimation of Crustacean Habitat Distribution by Counting Their Burrow on Amparu Tidal Flat, Ishigaki Island
AMPARU is a large tidal lagoon located on the west coast of Ishigaki Island, where a variety of small crabs range over. In these thirty years, however, accumulation of red clay from the watershed has been changing the topography and the hydraulic characteristics of the lagoon, and then changing the environments for the crabs to habitat there. This paper presents a result of a field survey that ...
متن کاملBurrow characteristics of the mud shrimp Austinogebia edulis, an ecological engineer causing sediment modification of a tidal flat
The mud shrimp Austinogebia edulis, being abundant in the intertidal zone of western Taiwan, constructs deep burrows (>1 m). This study highlights the potential of mud shrimps to modify sediment characteristics of the tidal flat by its burrowing behavior. We studied the structure of the burrow wall, compared the difference in the sediment composition of the burrow and the background sediment, a...
متن کاملProximal cues of pocket gopher burrow plugging behavior: influence of light, burrow openings, and temperature.
Burrow plugging is readily observed among mammals adapted for digging (i.e., fossorial mammals) as they create and maintain their burrows. We investigated the influence of light, burrow openings, and thermal environment as cues of pocket gopher (Thomomys mazama, Thomomys talpoides) behavior. When given free access to light and no light during artificial-burrow preference trials, both Thomomys s...
متن کاملThe Tuned Singing Burrow of Mole Crickets
During burrow digging by the mole cricket Scapteriscus acletus Rehn and Hubbard, the burrow is enlarged and shaped in a series of digging cycles, each lasting 1—2min, and song chirps are produced after every cycle. The song becomes up to 18 dB louder and acoustically purer during burrow building. The shape of the song pulse envelope changes so that its average power density becomes greater and ...
