The Red-crowned Crane Grus japonensis is an endangered species in East Asia. The western flyway population in China has been in steady decline in recent years because of the loss and deterioration of the natural wetland habitat it requires. To enhance this migratory Red-crowned Crane population, a project was designed to return captive Red-crowned Cranes to the wild in 2013 and 2015 in the Yancheng National Nature Reserve (YNNR). This reserve is the most important wintering site for the continental migratory population. The survival rate of introduced Red-crowned Cranes was 40%. However, aggregation of introduced and wild individuals was not observed. Introduced individuals did not pair with wild individuals nor did they migrate to breeding areas with them. They remained in the core zone of the YNNR over summer. Here, we report the first breeding of introduced Red-crowned Cranes in the YNNR in 2017 and 2018. Suitable rearing methods and the use of aircraft to inform them of the migration route are necessary. Further research is necessary to confirm the migratory status of the cranes that are reared in the reserve.

A self‑collected gargle sample, which avoids discomfort and largely reduces the dependency on medical resources, is emerging for detection of SARS‑CoV‑2. However, the incomplete usage of starting materials for both routine oropharyngeal swabs (OPS)/nasopharyngeal swabs (NPS) and saline gargle (SG) samples implies sensitivity can be further improved. Presented here is a bead‑based strategy for pre‑enrichment of SG samples, and results revealed that it acquired about 20 times the starting materials obtained from OPS samples for downstream detection of SARS‑CoV‑2. The sensitivity and specificity of this pre‑enrichment strategy were validated in 100 paired pre‑enriched saline gargle (PenSG) and OPS samples and 89 PenSG samples from healthy volunteers. In addition to detection of SARS‑CoV‑2, this pre‑enrichment strategy may also be implemented in more clinical settings to optimize detection of other diseases.
