The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]

open access: yes, 1984
Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...

Role of Non-Residential Larval Habitats in Aedes Spatiotemporal Egg Production

open access: yesLife
Aedes mosquitoes play a pivotal role as vectors of several arboviral diseases, presenting significant public health challenges worldwide. Their invasive success in tropical regions has raised substantial medical concerns. In Guatemala, Aedes mosquitoes are widely distributed and are the primary vectors of the dengue virus.

Systematic Engineering of Proteases in Saccharopolyspora Spinosa Reveals Synergistic Enhancement of Spinosad Biosynthesis via Substrate Flux Optimization

open access: yesAdvanced Science, EarlyView.
ARTP mutagenesis yielded Saccharopolyspora spinosa mutant D184 with improved extracellular nitrogen utilization. An integrated workflow of protease genetic manipulation, multi‐omics, and rational synergy design pinpointed a pepP‐clpP‐htpX synergistic triangular combination.

Development and silk production by silkworm larvae after topical application of methoprene

open access: yesScientia Agricola, 2002
Juvenile hormone analogues have been tested as insect growth regulators in silkworm (Bombyx mori), seeking an increment of silk production. These chemical products, when applied in small or moderate rates, promote the extension of the last larval instar.

A Review of Spinosad as a Natural Product for Larval Mosquito Control

open access: yesJournal of the American Mosquito Control Association, 2010
The effectiveness of spinosad for larval mosquito control is summarized based on available published literature and some heretofore unpublished studies. Spinosad is highly active against larvae of all mosquito species tested thus far. It is effective at similar dosages for all larval mosquito instars, with peak cumulative mortality occurring at 72 h ...

Guidelines for the Anti‐Obesity Assays of Food Bioactives in Caenorhabditis elegans

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
This Guideline uses Caenorhabditis elegans as a model organism to systematically explain and summarize the research strategies and experimental methods for the anti‐obesity effects of food bioactives. ABSTRACT The obesity has become a global public health problem and is closely related to a variety of chronic diseases.

Multimodal Locomotion of Soft Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Rangewide responses of Mimulus cardinalis to an extreme heat event

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Extreme events are an understudied aspect of ongoing anthropogenic climate change that could play a disproportionate role in the threat that rapid environmental shifts pose to natural populations. Methods We exposed plants originating from seeds that were harvested before (ancestors) and after (descendants) multiple extreme heat events
