Particular emphasiswas placed on collecting from calcareoussands and gravels, since most workers to datehave reported on the more abundant epifaunalspecies (Schellenberg, 1938; Barnard, 1965). Inaddition, efforts were made to collect completeseries of life history stages, and to study morphologicalvariations, behavior, and general ecologyof the more abundant species.

(Crustacea, Decapoda Natantia, Pontoniinae) from Fiji<br/><br/>Author(s): Bruce, AJ<br/><br/>Abstract: Periclimenes hirsutus, a new species of pontoniid shrimp collected inFiji, is described. The shrimp was obtained from a littoral echinoid. The distinctivefeatures of the shrimp and its relationship to other species are discussed.

Hawaiian Plant Studies 36<br/><br/>Author(s): St. John, Harold<br/><br/>Abstract: Much of the mountain Haleakala onMaui is of easy access and has a flora quite wellknown. Kipahulu Valley is an outer valley atthe southeast corner of the great volcano. It isremote, difficult of access, and its middle andupper parts have a dense, wet, virgin vegetation.An attempt is now being made to acquire titleto it and to preserve it as a wilderness or naturepreserve.

Up to an elevation of atleast 3,000 feet, the major variables of the physical environment are rainfall, rocktexture, and sea breezes.The lichen Stereocaslon vulcani, the most abundant and widespread pioneerorganism, shows a marked preference for regions of higher rainfall, but all speciesof Parmelia and Cladonia, together with an unidentified crustose lichen, were foundonly in areas of lower rainfall. The mosses and blue-green algae prefer relativelyhumid regions, but Campylopus densifolius is able to grow in some areas that aretoo dry to permit growth of Rhacomitrium lanuginosum,Rough aa lava provides a more favorable substrate for Stereocaulon vulcani thandoes the smoother pahoehoe, but this effect becomes less pronounced with increasingrainfall. Thus, aa creates a more moist environment than does pahoehoe, probablybecause its highly irregular, pitted surface is better able to trap and retain rainwater.A possible contributing factor is the greater susceptibility of aa to chemical weathering.On some lavas, lichens and mosses preferentially colonize seaward-facing rocksurfaces. This is ascribed to water vapor conveyed inland by sea breezes. Nutrientsin wind-borne ocean salts may play a secondary role.The net effect of rainfall , rock texture, and, in some cases, sea breezes determinesthe abundance and gross vegetative morphology of Stereocaulon vulcani, its abilityto gain a foothold , and the level of maturity which it can attain. The successfulnessof S. vulcani in colonizing lava can be ascribed to its ability to invade vesicles andnarrow recesses in the rock, its ability (or that of its associated microflora, or both)to accelerate the chemical weathering of the rock, and its rapid rates of dispersal,establishment, and growth. Under optimal conditions, S. vulcani spreads rapidlyover a fresh rock surface, and dominates the pioneer community, probably bypreempting space which might otherwise be occupied by slower-growing species.In one particularly damp area, mosses and blue-green algae increase at the expenseof S. vulcani, In one exceptionally dry area, Stereocaulon is initially the mostabundant lichen on the aa flows, but it never attains maturity, and its numericalimportance is gradually superseded by that of Parmelia and Cladonia, which arebetter adapted to dry conditions.No evidence of "mat" formation was found. Vascular plants spring up in crevices,while lichens, mosses, and algae occupy the intervening rock surfaces. Fri, 01 Jan 1971 00:00:00 GMT
