Última Efecto de la salinidad y la temperatura sobre el ciclo de vida de cangrejos estuariales (Decapoda, Grapsidae). OceanDocs Bas, C.. El ciclo de vida de los cangrejos verdaderos (Crustacea, Brachyura) incluye en la mayoria de los casos cuatro etapas. Una etapa embrionaria, en la cual los huevos en desarrollo protegidos por una membrana de varias capas, se mantienen adheridos a los ple6podas de la hembra, expuestos a las mismas condiciones ambientales que el adulto . Posteriormente una etapa larval planct6nica y finalmente una fase juvenil y una adulta, ambas bent6nicas en igual o diferente ambiente . Muy frecuentemente [as historias de vida de los organismos son referidas como rigidamente definidas para cada especie, sin embargo existen numerosos ejemplos en invertebrados donde las caracteristicas del desarrollo y la reproducci6n de una especie son ampliamente influenciadas y...

Un estudio ecológico de la salina marina Pozos Colorados se llevó a cabo entre enero y agosto de 1987. Si bien las dos estaciones de muestreo presentaron amplias diferencias entre si; en general la dinámica del ecosistema dependió aparentemente de la salinidad, la cual varió entre 75 y 341 °/oo; su incremento y la disminución del nivel de agua, al parecer generaron aumento de la temperatura y disminución del oxígeno disuelto, con rangos de 26,3 y 41 °C para la primera y O y 5,4 mg/l para el segundo. Aunque en promedio el pH fue neutro (7,5), este sistema reductor, caracterizado además por abundante materia orgánica, generó en ocasiones una ligera acidez (6,7). La producción primaria neta fue negativa en la mayoría de los casos, como resultado de una...

The effect of temperature on cyst hatching larval survival and biomass production for different geographical strains of brine shrimp <i>Artemia</i> spp. OMA Vanhaecke, P.; Sorgeloos, P.. The effect of temperature on different geographical strains of <i>Artemia</i> has been studied for the following criteria: the hatchability of the cysts, the resistance of the larvae to high temperature (34°C) and the biomass production of larvae cultured under standard conditions. Experimental temperatures ranged from 25° to 37°C for the hatching criteria and from 20° to 32.5°C for the biomass production.Both the hatching percentage and growth performance are affected by temperature. However, the relative and quantitative impact of temperature varies widely among <i>Artemia</i> strains. This is also the case for the temperature resistance of the larvae. The impact of increasing temperatures on cyst hatching as well as the...

Ano: 1989 URL: http://www.vliz.be/nl/open-marien-archief?module=ref&refid=3194 A comparison between models describing the influence of temperature on the development rate of copepods OMA Heip, C.H.R.. Four mathematical expressions relating development time to temperature are compared. All four yield good predictions of the development rate of the copepod <i>Tachidius discipes</i>. The use of the equation of Belehradek is criticized. It is concluded that the power equation D= aT<sup>b</sup> gives the best approximation in this case.

Combined effects of temperature and salinity on the survival of <i>Artemia</i> of various geographical origin OMA Vanhaecke, P.; Siddall, S.E.; Sorgeloos, P.. The brine shrimp inhabits geographically isolated biotopes with specific biotic and abiotic conditions. This has resulted in various geographical strains between which marked genetica, biological and chemical differentiation exists. The response of 13 different <i>Artemia</i> strains to the combined effect of temperature and salinity has been studied. Experimental temperatures tested ranged from 18 to 34°C and salinities from 5 to 120 promille. Except for Chaplin Lake (Canada) <i>Artemia</i> , all strains showed high survival over a wide range of salinities (35-110 promille). For all strains the common temperature optimum was between 20 and 25°C. Interaction between temperature and salinity was negligible or very limited....

Ano: 1984 URL: http://www.vliz.be/imisdocs/publications/261924.pdf Studies of the life-history and energetics of marine and brackish-water nematodes: 1. Demography of <i>Monhystera disjuncta</i> at different temperature and feeding conditions OMA Vranken, G.; Herman, P.M.J.; Heip, C.H.R.. Aspects of the demography of <i>Monhystera disjuncta</i> were investigated at different feeding conditions (monoxenic cultures with different bacterial strains, and different densities in the feeding suspension with one strain). Embryonic development time, minimum generation time, egg deposition rate and adult longevity depend on temperature, quality and quantity of food offered. Body mass at maturity is an allometric function of food density. It is shown that a previously inferred selectivity in food uptake is an artifact of culture conditions. pH buffering and addition of sterols permit culture of the species on a wide variety of bacterial strains. <i>M. disjuncta</i> is less well adapted to take advantage of high food density...

GONZALO; VELOSO,ALBERTO; JIMÉNEZ,PAULINA; MÉNDEZ,MARCO A.. The assimilation efficiency of Bufo spinulosus tadpoles from four localities in Chile was evaluated for two different temperatures (15 and 25 ºC) and two different diets (low nutritional quality diet (LQD): 22.28 mg g N-1; high nutritional quality diet (HQD): 47.53 mg g N-1) using ash as a marker of digestion. Results showed that geographic origin did not affect assimilation efficiency, while the relationship observed between temperature and diet quality was significant. Assimilation efficiency was greater for the HQD when tadpoles were maintained at 15 °C, instead significant differences were not found between diets for tadpoles maintained at 25 °C. Our results suggest that the effect of temperature on digestive processes is more relevant than its effect...
