Saleh R, Betancor M, Roo J, Benitez-Santana T, Zamorano MJ & Izquierdo MS (2015) Biomarkers of bone development and oxidative stress in gilthead seabream larvae fed microdiets with several levels of polar lipids and α-tocopherol. (stir.ac.uk)
Sea bream larvae fed diets without PL supplementation showed the lowest survival, growth and stress resistance, whereas increase in PL, particularly KPL, markedly promoted larval survival and growth. (stir.ac.uk)
Indeed, dietary -tocopherol decreased the oxidative stress in the larvae as denoted by the reduction in larval TBARs contents and gene expression of SOD and CAT, but not GPX. (stir.ac.uk)
While Anopheles larvae abundance in habitats is driven by multiple, interconnected factors - amongst which the NDVI - and precipitation events, the presence of vector imagines was found to be correlated negatively to remotely sensed LST and positively to the cumulated amount of rainfall in the preceding 15 days and to the Normalized Difference Pond Index (NDPI) within the 500 m buffer zone around capture points.

The morphological development of the visual apparatus of T. maccoyii and S. lalandi is described by histological analysis and microspectrophotometry (MSP) and the visual ability of larvae is examined through behavioural experimentation. (edu.au)
The aim of this study was to describe the development of eggs and larvae of N. vlaminghi and determine their distributions in the Upper Swan Estuary in relation to salinity, temperature and salinity stratification during January-February 2013 and December 2013-January 2014. (edu.au)
The abundances of N. vlaminghi eggs and larvae were positively correlated with salinity and negatively correlated with stratification. (edu.au)
The distribution of eggs was more restricted than that of the larvae, which was attributed to the development and morphology of the larvae. (edu.au)
Wild-caught lumpfish displayed higher fertilization and hatching success compared to captive lumpfish, whereas other biological variables like egg size, egg/larvae dry weight and respiration, and larval morphometry, were not significantly different between wild and captive lumpfish. (nofima.no)
The survival, behavior, and competence period of lecithotrophic larvae depends not only on the energy allocation transferred by maternal colonies, but also on the amount of energy consumed to sustain embryonic, larval, and post-larval development. (ekt.gr)
These results are in accordance with the larval behavior of these three species, since C. rubrum larvae are characterized by their high swimming activity frequency, P. clavata larvae are almost inactive, and the swimming activity frequency of E. singularis larvae is high, although variable. (ekt.gr)
In Drosophila, all growth occurs during the larval stage when larvae constantly feed, and as a result their body mass increases approximately 200-fold within 4 d, largely due to de novo lipogenesis. (sdbonline.org)
During this transition, feeding is inhibited, and after pupariation, feeding is impossible, thus the larval-pupal transition marks when energy metabolism is switched from energy storage by lipogenesis in larvae to energy utilization by lipolysis in pupae (Xie, 2015). (sdbonline.org)
At an ambient temperature of 25°C, eggs typically take 18-24 h to hatch followed by the larval stage which spans for ~4 days, during which developing larvae pass through three instars [ 1 ]. (biomedcentral.com)
Survival6
Overall, we found no impact of any pesticide on immature development time and relatively weak effects on larval herbivory or survival to adulthood. (nature.com)

Data currently exist on the influence of constant and fluctuating adult environmental temperature on adult Anopheles gambiae s.s. survival and on the effect of larval environmental temperature on larval survival, but none on how larval temperature affects adult life-history parameters. (biomedcentral.com)
The data also suggest that differences between the temperatures of the larval and adult environments affects adult mosquito survival. (biomedcentral.com)
Environmental temperature affects Anopheles survival directly during the juvenile and adult stages, and indirectly, since temperature during larval development significantly influences adult survival. (biomedcentral.com)
Embryonic3
Development from the initial collection (IC) point until the total absorption of the yolk lasted 315 h, at an average temperature of 27.45 +/- 2.13 degrees C.

Adult8
A secondary challenge in disentangling the role of pesticides in butterfly population ecology is that chemicals can act on either the larval or adult stage. (nature.com)
Upon emergence into imagoes, individual adult females were either left at their larval temperature or placed at a different temperature within the range above. (biomedcentral.com)
The effect of a 4°C increase in larval temperature from 27°C to 31°C depended on the adult environmental temperature. (biomedcentral.com)
This may increase egg and larval densities in the region, which could increase in mortality levels of these early life history stages and reduce recruitment of N. vlaminghi into the adult population. (edu.au)
Injected directly into the trunk of the tree, TreeAzin halts larval development and prevents adult emergence of EAB. (thetreespecialists.com)
Previously we have reported that selection for faster pre-adult development reduces development time (by ~19 h or ~11%) and clock period (by ~0.5 h), suggesting a role of circadian clocks in the regulation of development time in D. melanogaster . (biomedcentral.com)
We assayed the duration of three pre-adult stages in the faster developing (FD) and control (BD) populations under a variety of light regimes that are known to modulate circadian clocks and pre-adult development time of Drosophila to examine the role of circadian clocks in the timing of pre-adult developmental stages. (biomedcentral.com)
The pupal stage starts after the third instar larval stage, lasts for another 4 days, subsequently leading to wing-pigmentation followed by adult emergence, hence the entire pre-adult developmental duration of Drosophila spans ~9 days. (biomedcentral.com)
Mortality3
While this reduction is partly due to the indirect effect of habitat loss (i.e., large fields with frequent herbicide inputs have fewer floral resources), intensification can also have direct effects by exposing individuals to pesticide residues that increase mortality or impair development. (nature.com)
Scientists from Oregon State University looked into how larval fish growth and mortality will change in warmer conditions as the climate crisis leads to marine heat waves. (org.in)
High early mortality and larval malformations have hindered the successful production of quality juveniles. (edu.au)

The dramatic change in water temperature caused by such extreme warm water anomalies increased black rockfish growth in the larval stage, the scientists noted. (org.in)
Remotely sensed geographical and meteorological factors, including precipitations, temperature, as well as vegetation, humidity and land cover indicators could be used as explanatory variables for surface water presence, larval development and imagines densities. (biomedcentral.com)
The purpose of the present study was to determine the effect of temperature on brood development of the parasite and on the degree of synchronization with the molting of its host. (georgiasouthern.edu)
A smaller percentage of the intermolt period elapsed between larval release and shrimp molting at 23 C (0.0%) than at 15 C (3.1%), indicating closer synchronization between host molting and parasite reproduction at the warmer temperature. (georgiasouthern.edu)
However, temperature also shapes mosquito life-history traits that are associated with vector-competence and determines mosquito population density: a warmer environment leads to faster development and smaller adults. (biomedcentral.com)
Metabolic rate is, in part, positively correlated with temperature. (encyclopedia.com)
