  • survival
  • Survival and development were compared for larvae from two populations (Chicago, IL, and Queens, NY) on six diets containing varying levels of Fe (69-237 mg/liter) and for three populations (Illinois and New York plus Hohhot, Inner Mongolia, China) under four larval chill treatments (6, 9, 12, or 16 wk of development before chill). (usda.gov)
  • Larval survival and percentage pupation significantly decreased and developmental time slightly increased with increasing Fe levels in the diet. (usda.gov)
  • Larval survival and percentage of pupation were highest, adults weighed the most, and developmental time was shortest when larvae were reared on a pourable modification of the Enaphalodes rufulus (Haldeman) (ER) diet. (usda.gov)
  • Using long videos of foraging fish larvae, we provide a framework for the automated detection of prey acquisition strikes, a behavior that is infrequent yet critical for larval survival. (biologists.org)
  • Studies on adult mosquitoes will include their survival and flight range, which are crucial to their vectorial capacity, and feasibility of control by anti-larval methods. (europa.eu)
  • Of the four candidate probiotics tested, only Kocuria AP4 showed potential to increase larval survival. (openthesis.org)
  • chemical
  • By mimicking the chemical and temperature conditions of the mammalian stomach, this method frees parasites from the surrounding flesh and reduces the background of nonparasitic organisms. (fda.gov)
  • minimal
  • Advantages of the SFPE method include minimal disturbance at a sampling area, efficient and economical sample collection and laboratory processing, ease of identification, applicability in nearly all aquatic environments, and a potentially more sensitive measure of ecosystem stress. (jove.com)
  • video
  • This video documents methods for collecting coastal marine water samples and processing them for various downstream applications including biomass concentration, nucleic acid purification, cell abundance, nutrient and trace gas analyses. (jove.com)
  • Similar
  • Methods similar to those displayed here have previously been used in several deer mouse studies, yet no detailed protocol has been published. (jove.com)
  • Techniques
  • We use a combination of methods, which represent a dispersed field of scientific disciplines comprising already established protocols and some of the most recent techniques developed. (jove.com)
  • However
  • However, candling is the only method currently used for regulatory purposes with finfish. (fda.gov)
  • Probiotics are usually selected based on various in vitro characteristics, however, the methods used differ and are sometimes unsuccessful due to poor experimentation. (openthesis.org)
  • However, most of these efforts were either based on cultivation methods or relied on the generation of 16S rRNA gene fragments which were sequenced for final identification. (jove.com)
  • results
  • Prior to death in the first larval instar, Cam nulls show a striking behavioral abnormality (spontaneous backward movement) whereas a mutation, Cam 7 , that results in a single amino acid change (V91G) produces a very different phenotype: short indented pupal cases and pupal death with head eversion defects.

  • useful
  • This study focusing on imaging methods indicates that SBFI is extremely useful for analysis of large mm-scale samples of decalcified coral tissues. (jove.com)
