Thus far, contamination of potable groundwater supplies has not beena problem. Many of the injection wells, however, have not performed as designed, and aquifer clogging and reduced injection capacity have producednumerous well failures resulting in public health, legal, and financial problems.Factors most commonly responsible for the well problems have been unfavorablehydrogeology, underdesign of injection well capacity, poor effluent quality, andlack of injection well maintenance. Detailed study of clogging mechanisms in theimmediate vicinity of injection wells suggests that binding of pore spaces bynitrogen gas is the most important cause of aquifer clogging. Other cloggingmechanisms also operating are filtration of solid particles and growth ofmicroorganisms Mon, 01 Apr 1985 00:00:00 GMT http://hdl.handle.net/10125/926 Title: Two New Species of the Deep-Sea Cardinalfish Genus Epigonus (Perciformes, Apogonidae) from the Hawaiian Islands, with a Key to the Hawaiian Species<br/><br/>Author(s): Gon, O<br/><br/>Abstract: Two new species of deep-sea cardinalfish are described fromspecimens that were collected in Hawaiian waters. Epigonus glossodontus andE. devaneyi have fewer lateral-line scales than all known congeners exceptE. o/igolepis, to which they are most closely related. Epigonus glossodont us hastwo or three large, anteriorly projecting teeth on each side of the symphysis of thelower jaw, and both species have scales on the upper part of the snout. A key tothe Hawaiian species of Epigonus is provided.

Most of the calcareous tubeworms (Serpulidae, Spirorbidae) were collectedfrom shallow patch reefs in the Mba Passage off the northwest coast; theremaining worms came from the intertidal region of Suva Harbor on the southeastcoast of Viti Levu. The tubeworms Spirobranchus giganteus corniculatus andFloriprotis sabiuraensis were collected with live coral, and 12species were scrapedfrom coral rock. Extensive patches of a gregarious sabellariid occur in SuvaHarbor, and nereidids and spionids were found among the densely packedsabellariid tubes. Polychaetes in this collection are most similar to faunas ofeastern Australia, Japan, Hawaii, and Tonga, and least similar to those of theSocieties, Marquesas, and Tuamotus. These faunal affinities show a west to easttrend reflecting Ekman's rule, but could also be explained on the basis of samplingeffort.

The tissue elastic modulus near full hydration, for example, is 3.5 MPa in D. menziesii, 6.1 MPa in D. reticulata, and 18.2MPa in D. knudsenii. As a result of its intermediate tissue elastic properties, D.reticulata exhibits an intermediate capacity for maintaining high turgor pressuresas tissue water content decreases . These result s imply that tissue elastic propertiesare significantly associated both with the habitat in which a Dubautia speciesgrows and with its diploid chromosome number. The latter association is presumablyindirect, with the difference in chromosome number serving as a markerfor other significant genomic differences.

Hawaiian Plant Studies 103<br/><br/>Author(s): St. John, Harold<br/><br/>Abstract: This paper gives a monographic treatment, based on morphology,of Pleomele (Liliaceae) in the Hawaiian Islands. It recognizes as islandendemics three species on Hawaii, two on Oahu, and one each on Kauai,Molokai, Maui, and Lanai. The new species are P. auwahiensis, P. Halaapepe,P. kaupulehuensis, P. konaensis, and P. Rockii.

New findings thathave largely been developed or published since then are described; these encompassvegetation, soils, hydrology, climatology, and experimental, historical andevolutionary research. A brief comparison of canopy dieback in Hawaii with thatin other forest systems is made. New facts on the Hawaiian dieback are summarizedwithin the context of climatic instability, soil, and stand factors . Thesefacts are then related to ideas of environmental disturbance, disease , and cohortsenescence. There are strong indications that the primary factor causing 'ohi'adieback develop s in the dieback population itself due to synchronized aging ofcohort stands. External abiotic (environmental) and biotic stress factors (insectsand fungal pathogens) appear to play secondary and/or subsidiary roles , respectively.Based on this new knowledge, policy and management considerations arediscussed with regard to the role of dieback and its impact on preserve design,forest hydrology, and soil fertility . Finally, a number of recommendations aremade for new management-related research and for further research into theetiology of canopy dieback.

With the possibleexception of the exceedingly rare Amaranthus brownii, the island's endemicplants are present in small but stable populations. A total of 7 months of fieldwork, including the first extended winter expedition to the island , permittedexhaustive searches for rare species and opportunities to estimate populations ofwinter annuals. Apparently, only one alien plant, Portulaca oleracea, is abundanton the island. A second alien species, Nephrolepis multiflora, probably reachedthe island naturally via wind or bird dispersal and occurs in very limited numbers. Mon, 01 Apr 1985 00:00:00 GMT
