... multiple physiologically active spectral classes but they also display clear and distinct responses to wavelengths across the spectrum. We propose that the spectral classes demonstrated in each are related to visually guided ecological tasks of the larvae, which may differ between species. ‡ Author...

... effects of two stressors (high temperature and hypoxia) in yolk-sac larval (48–168 hpf) zebrafish ( Danio rerio ) energy budgets measuring, oxygen consumption rate, growth rate (absolute and specific), % net conversion efficiency, net cost of growth and scaling relationships. Embryos and larvae were...

... coral populations rely on the dispersal of larvae from neighbouring populations for the addition of beneficial genes/genotypes to their gene pool ( Munday et al., 2009 ; Quigley et al., 2019a , b ). With reduced reef connectivity, populations may not be able to adapt rapidly enough to cope...

... in Drosophila undergo a rapid and stereotyped aging program where they lose both cell membranes and nuclei. Whether LECs are capable of undergoing aging in a manner similar to AECs remains unknown. Here, we addressed this question in two ways. First, we looked for hallmarks of epidermal aging in larvae...

... understood. In this study of developmental stages of the Pacific oyster, Crassostrea gigas , thermal sensitivities were measured for growth, survivorship, protein synthesis, respiration and transport of amino acids and ions. At warmer temperatures, larvae grew faster but suffered increased mortality...

... wave at frequencies within the frequency range of hearing by fishes. We compared the acceleration at points on the sagitta, asteriscus and lapillus when the bladder was air filled with results from models using a water-filled bladder. For larvae of 8.5–18 mm in standard length, the air-filled bladder...

... variation of up to 430% in shell length occurred among 12 larval families. Protein was the major biochemical constituent in larvae, with an average protein-to-lipid content ratio of 2.8. On average, 86% of protein synthesized was turned over (i.e. only 14% retained as protein accreted), with a regulatory...

... rh2 opsins had duplicated. The current study has taken an opsin expression approach to characterize visual plasticity in cod towards different spectral light during the larval stage, to maturation and extreme seasonal changes in the Barents Sea. Our data suggest that opsin plasticity in cod larvae...

...Andres Carrillo; Matthew J. McHenry ABSTRACT A large diversity of fishes struggle early in life to forage on zooplankton while under the threat of predation. Some species, such as zebrafish ( Danio rerio ), acquire an ability to forage in the dark during growth as larvae, but it is unclear how...

...Michael J. O'Donnell; Esau Ruiz-Sanchez ABSTRACT In larvae of most Lepidoptera the distal ends of the Malpighian tubules are closely applied to the rectal epithelia and are ensheathed within the perinephric membrane, thus forming the rectal complex. The cryptonephric Malpighian tubules within...

...Isvarya Venu; Zachary Durisko; Jianping Xu; Reuven Dukas Larval and adult fruit flies are attracted to volatiles emanating from food substrates that have been occupied by larvae. We tested whether such volatiles are emitted by the larval gut bacteria by conducting tests under bacteria-free (axenic...

... has not been investigated. In this study, we tested the effects of different levels of suspended sediment on larval growth and development time in Amphiprion percula , a coral reef damselfish. Larvae were subjected to four experimental concentrations of suspended sediment spanning the range found...

...Zachary Durisko; Blake Anderson; Reuven Dukas We investigated whether adult fruit flies ( Drosophila melanogaster ) use cues of larvae as social information in their food patch choice decisions. Adult male and female fruit flies showed attraction to odours emanating from foraging larvae...

...Gregory Zilman; Julia Novak; Alex Liberzon; Shimrit Perkol-Finkel; Yehuda Benayahu SUMMARY Marine larvae are often considered as drifters that collide with larval collectors as passive particles. The trajectories of Bugula neritina larvae and of polystyrene beads were recorded in the velocity field...

... developmental stages and to examine whether the effects were more pronounced in larval stages developing in the open ocean. Oxygen consumption rate, total protein, dry mass, total lipids and C/N were determined in late-stage embryos, zoea I larvae and newly settled juveniles reared in ambient pH (7.93±0.06...

... zebrafish ( Danio rerio ) sense the flow created by adult predators of the same species. When placed together in a cylindrical arena, we found that larvae were able to escape 70% of predator strikes (mean escape probability P escape =0.7, N =13). However, when we pharmacologically ablated the flow-sensitive...

Edmunds; Vivian Cumbo; Tung-Yung Fan SUMMARY This study describes the effects of temperature on the respiration of brooded larvae of scleractinian corals, and evaluates the implications of these effects relative to seawater temperature when peak larval release occurs. Respiration rates...

.... Therefore, thermal tolerance of stage zoea I larvae was examined in two populations of the Chilean kelp crab Taliepus dentatus , which are separated by latitude and the thermal regime. We measured temperature-dependent activity, oxygen consumption,cardiac performance, body mass and the carbon (C...
