1. Use of osmoregulatory ability to predict invasiveness of the Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) an invader in Southern Brazil
Abstract The Indo-Pacific swimming crab Charybdis hellerii (A. Milne-Edwards, 1867) is native to the Indo-Pacific Ocean, and occurs as an invasive species along the Eastern American coast, where it was probably introduced in ballast water. The present study evaluated the osmoregulation and salinity tolerance of C. hellerii in Paranaguá Bay, Paraná, Brazil,

2. Interaction between thermoregulation and osmoregulation in domestic animals
ABSTRACT The ability to maintain core temperature as well as volume and composition of body fluids within narrow ranges is a major characteristic of mammals. Yet, the ability to maintain a stable core temperature often relies on physiological responses that perturb the stability of body fluids. A common thermoregulatory mechanism that affects body fluid home

3. Effects of Arbuscular Mycorrhiza on Osmotic Adjustment and Photosynthetic Physiology of Maize Seedlings in Black Soils Region of Northeast China
ABSTRACT To investigate the effect of arbuscular mycorrhiza fungi on maize growth, osmoregulation substances and photosynthetic physiology, a popular maize variety ZD 958 was measured under potted condition. Arbuscular mycorrhiza (AM) symbiosis promoted plant growth, and enhanced plant height, leaf length, mean leaf width and dry weight. Higher soluble sugar

4. Rhamdia quelen (Quoy & Gaimard, 1824), submitted to a stressful condition: effect of dietary addition of the essential oil of Lippia alba on metabolism, osmoregulation and endocrinology
RESUMO O objetivo deste estudo foi avaliar o efeito do óleo essencial de Lippiaalba (OELA) como aditivo em rações na ionoregulação, parâmetros metabólicos e expressão de hormônios hipofisários em jundiás, Rhamdiaquelen, submetidos a uma situação estressante (densidade de estocagem de 10,6 kg m-3 e espaço limitado). Os peixes foram alimentados c

5. Response mechanisms of Brachiaria brizantha cultivars to water deficit stress
Two cultivars of Brachiaria brizantha (Hochst ex. A. Rich) Stapf. (Syn. Urochloa) were evaluated for their adaptation to water deficit and the stress response mechanisms in a greenhouse experiment. The experimental design was in completely randomized blocks with a 2 × 2 × 4 factorial arrangement. The Marandu and BRS Piatã cultivars were evaluated under tw

6. Growth and osmoregulation in Salmo salar L. juveniles 1+, 1½ + and 2+ reared under restrained salinity
The freshwater phase of Atlantic salmon Salmo salar L vary between one and eight years. The reduction of the freshwater phase is desirable to reduce freshwater usage, human resources and to increase year round availability of pan-sized salmon. Three trials were conducted to investigate the possibility of supply the market in a year-round basis, with pan-size

7. Seasonal changes in fructan accumulation in the underground organs of Gomphrena marginata Seub. (Amaranthaceae) under rock-field conditions
Rock field plant species present several adaptations to the climatic characteristics and seasonality of this habitat. In this study, we evaluate under field conditions the seasonal changes in non-structural carbohydrate accumulation in tuberous organs of Gomphrena marginata. Tuber fragments of plants of G. marginata were sampled monthly for a year (August 20

8. Accumulation of organic and inorganic solutes in NaCl-stressed sorghum seedlings from aged and primed seeds
Although it has been known that the seed's physiological potential affects its response to osmoconditioning and abiotic stresses, researches involving seed aging and priming associated to abiotic stresses are scarce. The aim of this work was to evaluate the role of seed priming on salt tolerance in sorghum seedlings from seeds with two vigor levels (aged or

9. Caracterização estrutural do gene que codifica a histidina quinase slnCl1 e sua relação com a patogenicidade, osmorregulação e resistência a fungicidas em Colletotrichum lindemuthianum / Structural characterization of the gene slnCl1 coding for a histidine kinase and its relation to pathogenicity, osmoregulation and fungicide resistance in Colletotrichum lindemuthianum
O fungo filamentoso Colletotrichum lindemuthianum (Sacc &Magnus) Briosi &Cav., agente causal da antracnose, é um importante patógeno do feijoeiro comum (Phaseolus vulgaris L.). Esse fungo é um excelente modelo de estudo para o entendimento do processo de infecção de fungos fitopatogênicos. Por meio de mutagênese por inserção de plasmídeo foi obtido

10. Processos osmorregulatórios no caranguejo Dilocarcinus pagei (Decapoda, Trichodactylidae), um antigo invasor da água doce: estudo das atividades (Na,K)-ATPase e V-ATPase branquiais / Osmoregulatory processes in the crab Dilocarcinus pagei (Decapoda, Trichodactylidae), an old invader of freshwater: characterization of the gill (Na,K)-ATPase and V-ATPase activities
Os crustáceos são originariamente marinhos; ao longo da evolução, diversas espécies invadiram ambientes de salinidades menores, chegando à água doce. A capacidade dos crustáceos colonizarem com sucesso o ambiente dulcícola depende do desenvolvimento de mecanismos eficientes de hiperosmorregulação. A osmolalidade e a composição iônica da hemolin

11. Habitat, morfologia branquial e osmorregulação das arraias de água doce da bacia amazônica (Elasmobranchii: Potamotrygonidae) / Habitat, functional morphology and osmoregulation of Amazonian freshwater stingrays (Elasmobranchii: Potamotrygonidae)
Foram analisadas as relações entre a morfologia funcional das brânquias, fisiologia osmorregulatória e habitats das arraias de água doce da família Potamotrygonidae. A organização geral das brânquias dos potamotrigonídeos é semelhante aos demais elasmobrânquios. As hemibrânquias dos potamotrigonídeos possuem entre 74 a 103 filamentos. Em cada f

12. EFEITO DO CLORETO DE SÓDIO NA DIETA, DUREZA E pH DA ÁGUA NA SOBREVIVÊNCIA, CRESCIMENTO E FLUXOS IÔNICOS DE JUVENIS DE JUNDIÁ (Rhamdia quelen) / EFFECT OF DIETARY SODIUM CLORET, WATER HARDNESS AND pH ON SURVIVAL, GROWTH AND IONIC FLUXES OF SILVER CATFISH (Rhamdia quelen) JUVENILES
The purpose of this study was to verify the effect of dietary salt (NaCl) supplementation, water hardness and pH on growth, survival and ionoregulation of silver catfish (Rhamdia quelen) juveniles. In the first experiment, juveniles were fed with diets supplemented with 0.0; 0.5; 1.0 e 2.0 % NaCl and exposed to pH 5.5, 7.0 and 9.0 for 35 days. In the second
