This study investigates the adaptive mechanisms of the rare orchid Paphiopedilum purpuratum under ex situ conservation, uncovering physiological trade-offs such as enhanced seed production accompanied by lowered photosynthetic capacity and elevated oxidative stress. It further demonstrates that host nitrogen metabolism shapes root fungal communities, driving two contrasting adaptive strategies—stable, reorganized mycorrhizal networks and dynamic, pathogen-suppressive non-mycorrhizal shifts—providing a multi-level microbial framework for improving long-term ex situ conservation of rare orchids.

It revealed “dual characteristics” of the summer EASWJ during the last deglaciation: millennial-scale variability superimposed on a long-term weakening trend. More importantly, they found that orbital forcing and greenhouse gas (GHG) forcing drove the EASWJ in opposite directions

The results show that, on the interannual time scale, the northwest–southeast displacement of the EASWJ and the intensity of the EASM maintain a stable anti-phase relationship across all three periods: a northward shift of the jet corresponds to a stronger monsoon, and vice versa. However, the study identified a significant “mode shift” in the second MV-EOF mode: during the MCA and LIA, the dominant feature is an out-of-phase (in-phase) relationship between EASWJ and EASM intensities in the midlatitudes (subtropics), whereas during the PWP it is characterized by a zonal displacement of the EASWJ, with an eastward (westward) shift associated with a stronger (weaker) EASM.

New review challenges conventional wisdom, revealing land-atmosphere interactions play a crucial role even in wet monsoon climates.
