Biosynthesis and enzymology of the Caenorhabditis elegans cuticle: identification and characterization of a novel serine protease inhibitor. [PDF]

, 2006
The nematode Caenorhabditis elegans represents an excellent model in which to examine nematode gene expression and function. A completed genome, straightforward transgenesis, available mutants and practical genome-wide RNAi approaches provide an ...

Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

Remote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

A conserved metalloprotease mediates ecdysis in Caenorhabditis elegans [PDF]

, 2004
Molting is required for progression between larval stages in the life cycle of nematodes. We have identified four mutant alleles of a <i>Caenorhabditis elegans</i> metalloprotease gene, <i>nas-37</i>, that cause incomplete ...

Semi‐automated seal detection on the Western Antarctic Peninsula: an unsupervised machine learning approach for detecting ice seals in aerial survey data

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a semi‐automated, rule‐based image analysis pipeline to detect ice seals in aerial surveys of the Western Antarctic Peninsula during an unusually low sea ice year. By using simple hierarchical clustering instead of deep learning, the method substantially reduced human annotation effort while achieving 82% recall, identifying 758 ...

Effect of Periodic Fasting on Growth and Feed Efficiency in Giant Freshwater Prawn (Macrobrachium Rosenbergii, De Man 1879) [PDF]

, 2019
There are obstacles in the aquaculture business that is still often facedbyfarmers, one of the challengesisthe high price of commercial feed. Feed as an energy source for growth is a reasonably high-cost component in production that reaches 40-89 %.

Abundance and Identification of the Leafmining Guild on Apple in the Mid-Atlantic States [PDF]

, 2017
The leafmining guild on apple in the northeastern United States was studied from 1983 to 1988. Ten species of leafminers, all Lepidoptera, were encountered during the sampling. Phyllonorycter spp. (P. blancardella and P.

Historical remote sensing highlights long‐term persistence of Emperor Penguin (Aptenodytes forsteri) colonies

Remote Sensing in Ecology and Conservation, EarlyView.
Remote sensing can reveal population dynamics of Antarctic penguin colonies. In this study, we analyze emperor penguin (Aptenodytes forsteri) guano stains in remote sensing imagery and discover colony presence predating known records for 18 colonies across Antarctica.

Fluorescent Beads Are a Versatile Tool for Staging Caenorhabditis elegans in Different Life Histories

G3: Genes, Genomes, Genetics, 2016
Precise staging of Caenorhabditis elegans is essential for developmental studies in different environmental conditions. In favorable conditions, larvae develop continuously through four larval stages separated by molting periods.
