8 results for “salinity preference”
Choice consequences: salinity preferences and hatchling survival in the mangrove rivulus fish (Kryptolebias marmoratus)
<p>In heterogeneous environments, mobile species should occupy habitats in which their fitness is maximized. Mangrove rivulus fish inhabit mangrove ecosystems where salinities range from 0 to 65 ppt, but are most often collected at ∼25 ppt. We examined the salinity preference of mangrove rivulus in a lateral salinity gradient, in the absence of predators and competitors. Fish could swim freely for 8 h throughout the gradient with chambers containing salinities ranging from 5 to 45 ppt (or 25 ppt throughout, control). We defined preference as the salinity in which the fish spent most of their time, and also measured preference strength, latency to begin exploring the arena, and number of transitions between chambers. To determine whether these traits were repeatable, each fish experienced three trials. Mangrove rivulus spent a greater proportion of time in salinities lower (5–15 ppt) than they occupy in the wild. Significant among-individual variation in the (multivariate) behavioral phenotype emerged when animals experienced the gradient, indicating strong potential for selection to drive behavioral evolution in areas with diverse salinity microhabitats.We also showed that mangrove rivulus had a significantly greater probability of laying eggs in low salinities compared with in control or high salinities. Eggs laid in lower salinities also had higher hatching success compared with those laid in higher salinities. Thus, although mangrove rivulus can tolerate a wide range of salinities, they prefer low salinities. These results raise questions about factors that prevent mangrove rivulus from occupying lower salinities in the wild, whether higher salinities impose energetic costs, and whether fitness changes as a function of salinity.</p>
Physiological condition and salinity preference in freshwater migrating juvenile sockeye salmon
<p>The amount of time that juvenile salmon remain in an estuary varies among and within populations, with some individuals passing through their estuary in hours while others remain in the estuary for several months. Underlying differences in individual physiological condition, such as body size, stored energy, and osmoregulatory function, could drive individual variation in the selection of estuary habitat. Here we investigated the role of variation in physiological condition on the selection of estuarine and ocean habitat by sockeye salmon (<em>Oncorhynchus nerka</em>) smolts intercepted at the initiation of their 650 km downstream migration from Chilko Lake, Fraser River, British Columbia (B.C.). Behavioural salinity preference experiments were conducted on unfed smolts held in fresh water at three time intervals during their downstream migration period, representing the stage of migration at lake exit, and the expected timing for estuary entry, and ocean entry (0, 1, and 3 weeks after lake exit, respectively).</p>
Growth rate and oviposition preference of Oc. togoi & Ae. albopictus in salinity stress
<p><em><span>Ochlerotatus togoi</span></em><span><em> </em>is a salt-tolerant euryhaline mosquito that lays its eggs in rock pools. Although it is a pest that transmits flaviviruses and filarial worms to humans, ecological studies have not been actively conducted because of its limited habitat. Rising sea levels have created a favorable environment for <em>Oc. togoi</em> to survive; additionally, the incidence of <em>Oc. togoi</em>-borne diseases may increase with an increase in population of <em>Oc. togoi</em>. We examined oviposition and growth rates in the range of 0–35 psu to obtain ecological data for <em>Oc. togoi</em>. <em>Ochlerotatus togoi</em> exhibited the highest oviposition preference at 0 psu; however, the hatching rate was highest at 10 psu, the pupation rate was highest at 25 psu, and the emergence rate was highest at 5 psu. <em>Ochlerotatus togoi</em> showed the highest rate of growth into adults at 25 psu. The results were verified for statistical significance using Mann–Whitney U and Kruskal–Wallis H tests (post hoc test: Bonferroni), and a regression equation was generated for the incidence of adult <em>Oc. togoi</em> based on the change in salinity (y = −14.318 + 9.821x; y = adult incidence rate; x = salinity). The oviposition habits and developmental conditions of <em>Oc. togoi</em> were confirmed and the number of <em>Oc. togoi </em>was predicted based on the changes in sea level and ocean salinity. The results of this study are expected to be used for controlling salt-tolerant vectors and responding to vector-borne diseases.</span></p>
