THE IMPACT OF INSTRUCTIONS ON INSTRUCTIONS "INSTRUCTIONS AND EXCURSIONS" IN THE PRE-UNIVERSITY STAGES


Coexistence patterns of sympatric giant pandas (Ailuropoda melanoleuca) and Asiatic black bears (Ursus thibetanus) in Changqing National Nature Reserve, China

Similar species may co-occur in sympatry because of the partitioning of habitat use and resources at different spatial and temporal scales.Understanding coexistence patterns of species may contribute to further uncovering the underlying coexistence mechanisms, and ultimately benefit the conservation of threatened species.In this study, camera trapp

Improving Expression of Pepsinogen A from Homo sapiens in Aspergillus niger by Using a Multi-Copy Gene Knock-in Strategy

Pepsinogen A (PGA) plays an important role in the treatment of human gastrointestinal diseases.At present, PGA is mainly extracted from pig stomach, so its source is very limited and its price is very expensive.Production of PGA by microbial fermentation using an engineered strain with high PGA yield would be an ideal solution.This paper presents a

Single-cell sequencing provides clues about the developmental genetic basis of evolutionary adaptations in syngnathid fishes

Seahorses, pipefishes, and seadragons are fishes from the family Syngnathidae that have evolved extraordinary traits including male pregnancy, elongated snouts, loss of teeth, and dermal bony armor.The Tamper Proof Case developmental genetic and cellular changes that led to the evolution of these traits are largely unknown.Recent syngnathid genome
