A Fish Out Of Water: Gill And Skin Remodeling Promotes Osmo- And Ionoregulation In The Mangrove Killifish Kryptolebias Marmoratus, Danielle M. Leblanc, Chris M. Wood, Douglas S. Fudge, Patricia A. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

The euryhaline, amphibious mangrove killifish Kryptolebias marmoratus is known to survive weeks out of water in moist environments. We tested the hypothesis that the skin is a site of osmo- and ionoregulation in K. marmoratus. We predicted that under terrestrial conditions, gill and skin remodeling would result in an enhanced role for skin and a diminished role for the gills in osmo- and ionoregulation. Fish were exposed to water—either freshwater (FW, 1‰) or hypersaline water (saltwater [SW], 45‰)—or air over a moist surface of FW or SW for 9 d and then recovered in water. When fish were emersed …

Estimate Of The Maximum Sustainable Yield Of Sergestid Shrimp In The Waters Off Southwestern Taiwan, Chin-Cheng Wu, Ching-Hsiewn Ou, Wen-Pei Tsai, Kwang-Ming Liu

Journal of Marine Science and Technology–Taiwan

The sergestid shrimp, Sergia lucens is one of the major marine resources in the waters off southwestern Taiwan. The maximum sustainable yield (MSY), total allowable catch (TAC) and fishing effort at MSY (EMSY) of the sergestid shrimp in this area were estimated to be 1008 tons, 907 tons and 11292 vessel-day, respectively by using the surplus production model with deterministic observation-error estimator approach based on a catch and effort series from 1997-2008. Furthermore, the mean MSY, TAC, and EMSY with 95% CI were estimated to be 1011 (842-1243) tons, 910 (758-1119) tons, and 11296 (10758- 11807) vessel-day, respectively from the …

Evaluation Of Soybean Meal As A Protein Source And Its Effect On Growth And Nitrogen Utilization Of Black Sea Turbot (Psetta Maeotica) Juveniles, Murat Yigit, Sebahattin Ergün, Ali Türker, Burcu Harmantepe, Adnan Erteken

Journal of Marine Science and Technology–Taiwan

Three experimental diets were formulated to be isonitrogenous (550 g kg-1 protein) and iso-caloric (20.5 kJ gross energy g-1 diet) by substituting fish meal (FM) for defatted soybean meal (SBM) at levels of 0, 10 and 20% replacement in order to evaluate the effects of replacing FM with defatted SBM in diets for Black Sea turbot. Diets were fed to triplicate groups of young Black Sea turbot (mean initial weight of 30.2 ± 0.2 g) for 60 days. Turbot fed all three diets had no significant difference (P > 0.05) in final weight, specific growth rate, nutrient utilization, Nitrogen loss or …

Osteology, Natural History Notes, And Phylogenetic Relationships Of The Poorly Known Caribbean Frog Leptodactylus Nesiotus (Anura, Leptodactylidae), María Laura Ponssa, Michael J. Jowers, Rafael O. De Sá

Biology Faculty Publications

The Leptodactylus melanonotus group consists of 15 species, but references to skeletal characters are available for only three species: L. leptodactyloides, L. melanonotus, and L. diedrus. Leptodactylus nesiotus is a member of the melanonotus group known only from the type locality, Bonasse swamp, on the Southwestern peninsula of Trinidad, Trinidad and Tobago. This species has been categorized as vulnerable given its restricted distribution. Herein, we report the adult osteology of L. nesiotus, the skeletal characters are compared with the available data from other Leptodactylus species. A phylogenetic analysis recovers a paraphyletic L. melanonotus group relative to the L. …

A Novel Method For Evaluating The Release Of Fermentable Sugars From Cellulosic Biomass, Rafael Jiménez-Flores, Gina Fake, Jennifer Carroll, Elizabeth Hood, John Howard

Dairy Science

Efficient hydrolysis of cellulosic biomass into free sugars for the production of bioethanol would allow utilization of an abundant and renewable natural resource. However, complex microcrystalline cellulose in biomass resists digestion. A preferred method to deconstruct cellulose is using enzyme cocktails, but the presence of multiple enzymes with synergistic outcomes for this process complicates direct biochemical analysis as a reliable indicator of deconstruction. Methods to detect release of free sugars rather than direct measurement of enzymatic activity are available but are time-consuming, and do not reflect the production of metabolic inhibitors of microbial growth which may interfere with the subsequent …

Population Status Of Chuck-Will’S-Widow (Caprimulgus Carolinensis) In The Bahamas, William K. Hayes, Elwood D. Bracey, Melissa R. Price, Valerie A. Lee, Eric Gren, Caroline Stahala

Faculty Works

The Chuck-will’s-widow (Caprimulgus carolinensis) in the Bahama Islands has been regarded as a rare to uncommon winter visitor. We conducted breeding season surveys on the three largest northern islands (North Andros, Grand Bahama, and Great Abaco) to examine the status of this species. We encountered singing birds on most survey routes on all three islands, suggesting that sizeable breeding populations are widespread in the northern Bahamas with an aggregate estimate of 500–1,000 pairs. Our density estimates were somewhat less than those from the primary range in the United States, suggesting either a lower carrying capacity in the Bahama Islands or …

Lutein Exposure, In Ovo Or In The Diet, Reduces Parameters Of Inflammation In The Liver And Spleen Laying-Type Chicks (Gallus Gallus Domesticus), L.S. Meriwether, B. D. Humphrey, D. G. Peterson, K. C. Klasing, E. A. Koutsos

Animal Science

These trials examined whether the demonstrated effects of embryonic and dietary carotenoid exposure on the inflammatory immune response in fast growing chickens also occur in slow growing chickens. The systemic and local inflammatory responses of chicks were examined in two experiments with two in ovo lutein levels (C+, carotenoid replete; or C−, carotenoid-deplete), two dietary lutein levels (0 or 40 mg lutein/kg diet), and two inflammatory challenges [no exposure or lipopolysaccharide (LPS)-vaccinated]. At 24 h after LPS vaccination, spleen weight was not affected by diet or in ovo lutein, but liver weight increased from C+ eggs (p < 0.01), and in LPS-vaccinated chicks fed 0 mg lutein (p < 0.05), but not in chicks fed 40 mg lutein. Plasma carotenoids and liver carotenoids were reduced post-LPS (p < 0.05). Splenic IL-6 mRNA abundance was the greatest post-LPS in C− chicks fed 40 mg lutein vs. C+ chicks fed 40 mg lutein (p < 0.05). Hepatic IL-6, iNOS and TGFβ and splenic iNOS and TGFβ were not …

Marine Aquarium Fish Managed Fishery, K. A. Smith, Stephen J. Newman, G. M. Cliff

Ecologically Sustainable Development (ESD) series

Ecologically Sustainable Development (ESD) is the concept that seeks to integrate short and long-term economic, social and environmental effects in all decision-making. The Western Australian Government is committed to the concepts of ESD and these principles are implicitly contained in the objectives of the Fisheries Resources Management Act 1994 (FRMA).

Vocal Learning In Grey Parrots: A Brief Review Of Perception, Production, And Cross-Species Comparisons, Irene M. Pepperberg

Sentience Collection

This chapter briefly reviews what is known—and what remains to be understood—about Grey parrot vocal learning. I review Greys’ physical capacities—issues of auditory perception and production—then discuss how these capacities are used in vocal learning and can be recruited for referential communication with humans. I discuss cross-species comparisons where applicable and conclude with a description of recent research that integrates issues of reference, production and perception.

Kdr-Lacz-Expressing Cells Are Involved In Ovarian And Testis-Specific Vascular Development, Suggesting A Role For Vegfa In The Regulation Of This Vasculature, Rebecca C. Bott, Debra T. Summers, Anna M. Fuller, Ryann M. Mcfee, Ningxia Lu, Renee M. Mcfee, Andrea S. Cupp

Department of Animal Science: Faculty Publications

Our objectives were to evaluate kinase insert domain protein receptor (KDR)-β-galactosidase (LacZ) expression as a marker for vascular development during gonadal morphogenesis and to determine whether any novel non-angiogenic KDR-LacZ expression was present in mouse testes or ovaries. Gonads were collected from mice expressing LacZ driven by the Kdr promoter (KDRLacZ) from embryonic day 11 (E11) through postnatal day 60 (P60). At E11.5, mesonephric cells expressing KDR-LacZ seemed to migrate into the developing testis and surrounded developing seminiferous cords. Cells expressing KDR-LacZ appeared in the ovary with no apparent migration from the adjacent mesonephros, suggesting a different origin of endothelial …

Landscape Factors Impacting Survival Of Sympatric Red-Necked Wallabies (Macropus Rufogriseus) And Swamp Wallabies (Wallabia Bicolor) In Urbanized Areas, Karen Zusi

Independent Study Project (ISP) Collection

Urbanization and infrastructure build-up often includes many processes that can damage the natural environment in surrounding areas. Road, powerline, and dam construction, as well as mining, drilling, and overall land-clearing, have severe impacts that resonate through the adjacent wildlife communities. Some species, however, are able to persist in the fringes of urban environments; the swamp wallaby, Wallabia bicolor, is one such example in Australia. A different species of macropod, the red-necked wallaby (Macropus rufogriseus), is similar to the swamp wallaby in many ways but has failed to persist in the outskirts of urban areas. This study aimed to quantitatively differentiate …

Rare, Threatened And Endangered Species Of Oregon (2010), James S. Kagan, Sue Vrilakas, Eleanor P. Gaines, Cliff Alton, Lindsey Koepke, John A. Christy, Erin Doyle

Institute for Natural Resources Publications

Extinction is a natural process. Today, however, plant and animal species are disappearing world-wide at an accelerated pace. Based on current trends, half of the species on earth will be extinct within the next 100 years. The major cause of this phenomenon is human caused changes to the environment, which continue to increase - in Oregon and throughout the world.

Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend on plant and animal products. About 50% …

Zoo Registrars: A Bewildering Bureaucracy, Irus Braverman

Journal Articles

While their counterparts in the museum world have received some scholarly attention, no scholarly account of zoo registrars has been published to date. Why bother studying zoo registrars? Firstly, in the (contained) wildness of the zoo, the registrar performs the role of law and order. She (typically this position is employed by females) manages the administrative side of the zoo: a junction between data management and small-scale legal administration. Secondly, registrars both depict and represent the significant transformations that have occurred in North American zoos over the last few decades, from insular urban institutions exhibiting exotic animals for entertainment, to …
