From April 2020 to June 2022, a Ca+lidar with dual-wavelength and narrow-band emitting lasers utilizing all-solid-state technology was employed to conduct observations in Beijing（40.41°N, 116.01°E） for a total duration of 1797.79 hours over 280 nights. A total of 286 sporadic Ca+layers were observed, with heights ranging from 88 to 120 km and densities varying from 5.33 to 2200 cm-3. We simultaneously observed the ionosonde, located 28 km from the lidar, and found a correlation of 61.89% between the sporadic Ca+ layer and the sporadic E layer. When the sporadic Ca+layer has a downward phase trend, there is a correlation of 76.84%. By excluding the influence of ionosonde sensitivity, we focus only on calcium ions that have a density exceeding 140 cm-3, which exhibit a correlation of82.25%. Above 100 km, the correlation significantly increases, reaching approximately 90%. Furthermore, the correlation between the sporadic Ca+ layer and the sporadic E layer is particularly noticeable during the summer season, reaching around 90%. This phenomenon can be attributed to the variations in metal ions that occur during different seasons.

Two questions in the research of animal personality—whether there is a correlation between a personality trait and individual reproductive success,and what is the genetic basis underlying a personality trait—remain *** addressed these two questions in three shrub-nesting birds,the Azure-winged Magpie(Cyanopica cyanus,AM),White-collared Blackbird(Turdus albocinctus,WB),and Brown-cheeked Laughingthrush(Trochalopteron henrici,BL).The personality type of an individual was first identified according to its response to a territorial ***,we compared the fleeing distance,breeding parameters,and differential expressed genes(DEGs) in the brain transcriptome between bold and shy *** the three species,bold breeders exhibited more aggressiveness towards an intruder of their territory than did shy *** reproductive success of bold breeders was significantly higher than that of shy breeders in AM but not in WB and *** three species shared one DEG,crabp1,which was up-regulated in bold relative to in shy *** regulating the expression of corticotropin-releasing hormone,higher crabp1 gene expression can decrease cellular response to retinoic ***,bold individuals are insensitive to external stresses and able to exhibit more aggressiveness to intruders than their shier *** is beneficial to bold individuals in AM but not in WB and BL because the former could evoke neighbors to make the same response of defending against intruders but the latter could *** a personality trait may have the same genetic basis across species,its correlation with reproductive success depends largely on the life history style of a species.

Drought(water shortage)can substantially limit the yield and economic value of rose plants(Rosa spp.).Here,we characterized the effect of exogenous calcium(Ca^(2+))on the antioxidant system and photosynthesis-related properties of rose under polyethylene glycol 6000(PEG6000)-induced drought *** levels,as well as leaf and root biomass,were significantly reduced by drought;drought also had a major effect on the enzymatic antioxidant system and increased concentrations of reactive oxygen *** of exogenous Ca^(2+)increased the net photosynthetic rate and stomatal conductance of leaves,enhanced water-use efficiency,and increased the length and width of stomata following exposure to ***-specific physiological responses were observed under different concentrations of Ca^(2+).Application of 5 mmol·L^(-1)Ca^(2+)promoted photosynthesis and antioxidant activity in the leaves,and application of 10 mmol·L^(-1)Ca^(2+)promoted antioxidant activity in the *** of exogenous Ca^(2+)greatly enhanced the phenotype and photosynthetic capacity of potted rose plants following exposure to drought ***,our findings indicate that the application of exogenous Ca^(2+)enhances the drought resistance of roses by promoting physiological adaptation and that it could be used to aid the cultivation of rose plants.
