According to the lecture, fish have a tendency to sink. And two physical features help keep them from sinking. Fins are one physical feature and they play a very important role to keep fish afloat. For example, sharks have fins that look and work like wings of aircraft. When a shark ...

Complete sequencing of the HSY and the corresponding X regions in papaya is highly desirable as it would unveil the genomic features and evolutionary events of young sex chromosomes in plants. The draft genome sequence of SunUp female plant provided the foundation for analyzing papaya genome compositi...

This study aimed to develop novel integrated analytical strategies for the functional characterization of fish diversity based on the quantification, prediction and integration of the chemical and physical features in fish muscles. Machine learning models with an improved random forest algorithm applied on...

摘要: Our standard fiber-FISH protocol can be employed on fixed cells stocked in many laboratories. We performed double fiber-FISH in species of fish from different orders. Fiber-FISH is a resource for compositional, structural and functional analysis of fish DNA....
Few fish moved among study pools, but the proportion of adults declined with repeated sampling, suggesting greater pool fidelity of juveniles. These results illustrate that intrinsic habitat features influence age- and size-class distributions in a resident tidepool sculpin species, with corresponding ...
