This study compares the reproductive strategies of two self‐incompatible orchids, Pholidota articulata (mass‐flowering) and Coelogyne prolifera (steady‐state flowering). Despite differences in pollinator visitation and pollinia transfer efficiency—higher in P. articulata—both species achieved similar natural fruit set rates over 3 years.

A comprehensive ecological index MRSEI based on MODIS was proposed. The new indicators of greenness, humidity, and dryness are more applicable to the ecological evaluation of the desertification steppes. The introduction of comprehensive salinity index can effectively reflect the issue of soil salinization. FROM‐TO vector transformation can effectively

This study analyzed the habitat suitability of the tufted deer, a rare and endemic ungulate in China, using the MaxEnt model and found that suitable habitats are mainly concentrated in Sichuan, Guizhou, and Yunnan provinces. However, the majority of these areas are not covered by existing protected areas, highlighting the urgent need to expand ...

We assessed interspecific differences in nutrient resorption efficiencies (N, P, K) of assimilative branches in three Calligonum species from the Junggar Desert. The results revealed distinct nutrient resorption strategies and scaling relationships among species, closely linked to both internal nutrient status and environmental factors.
