2007), suggesting a hydrosol filtration mechanism, in which particles are intercepted by the frontal surface of the gill filaments and adhere to the overlying mucous strings (Shimeta & Jumars
1991, Ward et al.
By now we had reached the bottom of the ropes fixed by Greg and George, so all we had to do was clip our jumars
to the lines and half-climb, half-pull on the jumar
as we ascended--but now I discovered that Cronlund did not have an ascender of any kind.
With her harness and helmet and Jumars
(mechanical rope ascenders), Nadkarni is a scientist able to connect with a popular audience.
Trophic groups were determined using Fauchald & Jumars
(1979) and Rouse & Pleijel (2001).
So in an effort to sort out my jumars
from my karabiners, I buckled on my harness, gathered up my ice axe and got ready to take the plunge (or hopefully not) to learn about mountaineering in Switzerland.
Mediomastus ambiseta is a non-selective subsurface-deposit feeding polychaete (Fauchald & Jumars
1979; Flint et al.
Although the available literature gives practically no information concerning the environmental particularities or habitat under which that fauna was collected, and though these families are geographically widely distributed and have been found in a broad variety of habitats, the fact that they are composed basically of mobile or discreetly mobile and mainly carnivorous species (Fauchald and Jumars
1979), could indicate that the polychaetes of the islands have been mainly collected from rocky environments, including dead coral substrates.
In addition, feeding modes of species were determined from the literature (Fauchald and Jumars
1979; Morris et al.
Particle capture by filter feeders, for example, differs considerably among sites because of velocity and organic content of water currents (Shimeta & Jumars
succinea is primarily a surface deposit feeder (Fauchald & Jumars
1979, Masterson 2008).
Minimizing the angles at the hinged joints along the walls decreased the amount of flow separation at the hinge (Nowell & Jumars
1987; Judge et al.
It has been suggested by many authors (Crisp 1955, Crisp 1974, Williams 1980, Nowell & Jumars
1984, Ertman & Jumars
1988, Eckman 1990, Harvey et al.
