Species identification in fish meal from urban fisheries biomass with DNA metabarcoding analysis
Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 562-571, December 2022., 2022 Fish species constructing fish meal (FM) made from urban fisheries biomass, which is fisheries by‐products collected downstream in the seafood supply chain were detected with a DNA metabarcoding method. 81–122 species were detected in the FM, and fish species indicated as Critically Endangered (CR) or Endangered (EN) on the International Union for ...

Comparing various sulfur sources for soybean grown on an acid Oxisol in Brazil
Agronomy Journal, Volume 114, Issue 6, Page 3420-3428, November/December 2022., 2022 Abstract A greenhouse experiment and a 2‐yr field trial were conducted to compare various S sources for soybean [Glycine max (L.) Merr.] grown on an acid Oxisol in Brazil. In the greenhouse, the sources included ammonium sulfate (AMS), monoammonium phosphate with a S ratio = 50:50 of AMS/elemental S (ES) – (AMS + ES), and ES + bentonite containing 90 ...

Scaling behavior in land markets [PDF]
Physica A326 (2003) 256-264, 2003 In this paper we present an analysis of power law statistics on land markets. There have been no other studies that have analyzed power law statistics on land markets up to now. We analyzed a database of the assessed value of land, which is officially monitored and made available to the public by the Ministry of Land, Infrastructure, and Transport ...
