  • larvae
  • The larvae of the last (fifth) instar have to reach a critical mass of about 5 g before specific hormones trigger the onset of metamorphosis, which involves a larval-to-pupal (metamorphic) molt. (biologists.org)
  • Knowing that the larvae can undergo additional larval-to-larval molts when they don't reach the critical mass for their metamorphic moult as a result of an insufficient supply of food, the team hypothesized that a positive regulator that drives molting regardless of body size must exist. (biologists.org)
  • Performing similar experiments with younger, fourth instar larvae further showed that this timer controls not only metamorphic molts but also larval-to-larval molts. (biologists.org)
  • A comparative analysis shows that a pedal plexus, adductors, a larval velum ring, velum retractors and a ventral larval retractor are commonly found among bivalve larvae, and thus most likely belong to the ground pattern of the bivalve larval musculature. (beds.ac.uk)
  • Based on our results, it is likely that many species exhibit this larval hanging behavior, and this could impact colony characteristics such as spatial organization and the care of developing larvae by nurse workers. (jove.com)
  • Once larval aggregations started to form, multiple internal and external temperatures, and weather observations were taken daily or every few days between 1400 and 1800 hours until pupation of the larvae. (usgs.gov)
  • Bacterial community structure was greatly shaped by mosquito larval feeding, and flavobacteria were much more abundant in the water column of natural tree holes after A. triseriatus larvae were removed ( 5 ). (asm.org)
  • species
  • Success in the larval life is one of the principal determinants for a successfull recruitment and it is an important element to evaluate a species fishery. (conicyt.cl)
  • Such adaptations are important, researchers at the University of Illinois atUrbana-Champaign say, because the larval fish of at least two species of notothenioids that inhabit the Ross Sea at McMurdo Sound and Terra Nova Bay surprisingly lack sufficient antifreeze to protect them through their first three months of life.

  • metamorphosis
  • Although it is known that the larval epidermis dies during metamorphosis and that TH induces keratinization and detachment of epidermis cells from culture dishes ( 5 , 6 ), we sought to determine whether this death occurs autonomously in vivo as a result of TH induction or indirectly by cell-cell interaction, perhaps as a result of the secreted proteases from the adjacent subepithelial fibroblasts. (pnas.org)
  • known
  • A key additional reason for the lack of known diversity in the Caenorhabditi s genus is that these so-called "soil nematodes" are rarely found in soil samples. (biomedcentral.com)
  • Heat generation in larval feeding aggregations (=maggot masses) is a well-known phenomenon, but it has not been quantitatively described. (usgs.gov)
  • cells
  • Green fluorescent protein (GFP)-tagged F. hibernum cells were quickly consumed by larval mosquitoes at an ingestion rate of 9.5 × 10 4 /larva/h. (asm.org)
  • system
  • Five major muscle systems were identified: a velum retractor, foot retractor, larval retractor, a distinct mantle musculature and an adductor system. (beds.ac.uk)
  • body
  • The two convex lobes of the D-shaped (veliger stage) or roundish (pediveliger-stage) larval shell are hinged and cover the soft body of the larva. (beds.ac.uk)
  • studies
  • Monitoring heart function in larval Drosophila melanogaster for physiological studies. (biomedsearch.com)
  • Our previous studies using some of the procedures described above showed that tree hole larval habitats of Aedes triseriatus mosquitoes contain diverse microbial components and that flavobacteria are a prominent bacterial group. (asm.org)
  • data
  • Here, we describe myogenesis of L. pedicellatus revealed by filamentous actin labelling and discuss the data in a comparative framework in order to test for homologous structures that might be part of the bivalve (larval) muscular ground pattern. (beds.ac.uk)
  • days
  • Flavobacterium hibernum , isolated from larval habitats of the eastern tree hole mosquito, A. triseriatus , remained suspended in the larval feeding zone much longer (8 days) than other bacteria. (asm.org)
  • layer
  • The expression patterns of specific DNA-binding factors that control eye development add an additional layer of complexity ( K umar and M oses 1997 ). (genetics.org)
