Thus, the Bureau shares a strong common interest with other federal administrative units, as well as with state, interstate, and international agencies, in protecting, enhancing, and ensuring the wise use of fish and wildlife in the Great Lakes Basin.</span></p>","largerWorkType":{"id":24,"text":"Conference Paper"},"largerWorkTitle":"Proceedings of the First Federal Conference on the Great Lakes","largerWorkSubtype":{"id":19,"text":"Conference Paper"},"conferenceTitle":"First Federal Conference on the Great Lakes","conferenceDate":"December 13-15, 1972","conferenceLocation":"Ann Arbor, MI","language":"English","publisher":"National Technical Information Service","usgsCitation":"Hester, F.E., 1973, The role of the Bureau of Sport Fisheries and Wildlife in the Great Lakes, <i>in</i> Proceedings of the First Federal Conference on the Great Lakes, Ann Arbor, MI, December 13-15, 1972, p. 39-43.","productDescription":"5 p.","startPage":"39","endPage":"43","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":324,"text":"Great Lakes Science Center","active":true,"usgs":true}],"links":[{"id":321616,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5746ccc5e4b07e28b662dd50","contributors":{"authors":[{"text":"Hester, F.

Brook trout (<i>Salvelinus fontinalis</i>), rainbow trout (<i>Salmo gairdneri</i>), and brown trout (<i>Salmo trutta</i>) have different relative proportions of visual pigments in their retinae. The visual pigment balance in wild cutthroat trout (<i>Salmo clarki</i>) is related to forest canopy (access to light) and season. The brown trout have a more red-sensitive and less labile pair of visual pigments than brook or rainbow trout, which respond to photic conditions by increasing the proportion of porphyropsin (in light) and increasing rhodopsin (in darkness). The brown trout have a high percentage of porphyropsin, regardless of experimental conditions. This result does not reflect an inability to form rhodopsin but rather may relate to a consistently high proportion of 3-dehydroretinol in the pigment epithelium.

The resulting equations can be solved accurately and efficiently using a numerical scheme which combines the finite element approach with the Galerkin method of approximation. Application of this numerical model to the Wairakei geothermal field demonstrates that hot-water geothermal fields can be simulated using numerical techniques currently available and under development.</p></div></div></div><ul id=\"issue-navigation\" class=\"issue-navigation u-margin-s-bottom u-bg-grey1\"></ul>","language":"English","publisher":"Elsevier","doi":"10.1016/0375-6505(73)90011-4","issn":"03756505","usgsCitation":"Mercer, J., and Pinder, G., 1973, Galerkin finite-element simulation of a geothermal reservoir: Geothermics, v. 2, no. 3-4, p. 81-89, https://doi.org/10.1016/0375-6505(73)90011-4.","productDescription":"9 p.","startPage":"81","endPage":"89","numberOfPages":"9","costCenters":[],"links":[{"id":218841,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"2","issue":"3-4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a14aae4b0c8380cd54ae1","contributors":{"authors":[{"text":"Mercer, J.W.
