Researchers investigated the population characteristics of two hybrid crucian carp strains based on one nuclear gene molecular marker, Transferrin (Tf). Interestingly, the nucleotide diversity of Tf alleles in cultured populations exceeded that of wild populations, and the network and genetic structure analyses failed to distinguish between wild and cultured populations. Additionally, AMOVA analysis indicated genetic differentiation among all six populations, the majority of the genetic variation (92.00%) was observed within populations. These findings providing an alternative perspective for germplasm evaluation of hybrid varieties and crucian carp breeding.

A research team led by National Agriculture and Food Research Organization (NARO) et al., has developed a method to enhance the nutritional value of black soldier fly larvae by reducing amino acid excretion. This increase in essential amino acid levels suggests that insects can be tailored to meet animal dietary needs.

Most corn and soybean fields in the U.S. are planted with herbicide-resistant crop varieties. However, the evolution of superweeds that have developed resistance to common herbicides is jeopardizing current weed management strategies. Agricultural robotics for mechanical weeding is an emerging technology that could potentially provide a solution. A new study from the University of Illinois Urbana-Champaign looks at the types of farmers and fields more likely to adopt weeding robots and at what stage of resistance development.
