title: Assessment of Physicochemical Properties of Cashew Apple through Computer Vision – Original Images, Data, and R Script

description: Three files have been attached: (1) Raw input images, (2) Wet chemistry data of cashew apples, (3) R script used for analysis in the study. 
(1) The presentation contains the original input images (6 varieties of cashew apple, 2 sample types [slice & whole], at 2 maturity stages [817 & 819]) and a glimpse of the preprocessing for generating input images for image-based metrics using the ImageJ plugin developed in this work. These were used for the proposed research paper “Assessment of Physicochemical Properties of Cashew Apple through Computer Vision.” 
(2) An MS Excel data of the wet chemistry analysis for 15 parameters of 6 varieties of cashew apples at 2 maturity stages with 3 replications is given in this file. The mean values of these 15 parameters were used as dependent variables in the study.
(3) For achieving data analysis using the 144 image-based metrics generated from the plugin using the above images. An R program was developed to (i) determine the strength of association between the wet chemistry and image-based parameters and graphically visualize the correlation, (ii) evaluate the range and ranking of the parameters correlation, (iii) develop the top three linear prediction models of wet chemistry based on the image-based parameters, and (iv) perform prediction and validation with visualization, employing the top-ranked prediction model to unseen images. The R script also includes the necessary data set used for the analyses.

title: Seasonal flooding amplifies the positive asymmetric response of ecosystem carbon exchange along the precipitation gradient in saline wetlands

description: Intensified precipitation variability profoundly affects saline wetland hydrological dynamics, potentially interfering with key carbon processes within ecosystems. However, the mechanisms underlying how precipitation changes affect ecosystems carbon processes in saline wetland remain unclear. Moreover, whether seasonal flooding influences wetland ecosystems' carbon processes response to precipitation changes is still poorly understood. Based on a six-year field precipitation experiment including five precipitation levels (-60%, -40%, +0%, +40%, and +60% of ambient precipitation) in the Yellow River Delta wetlands, we examined how seasonal flooding regulated ecosystem CO2 exchange (NEE), gross primary production (GPP) and ecosystem respiration (ER) response to precipitation changes. From 2018 to 2020, we acquired the aforementioned datasets concerning ecosystem carbon fluxes and environmental factors. Through the integration and statistical analysis of these datasets, we have summarised the following research findings. Over three years, ecosystem carbon fluxes exhibited a positive asymmetric response along the precipitation gradient, with the increment under wet treatments exceeding the reduction under dry treatments. Compared with the control, the -60% treatment significantly reduced GEP and ER by 9.7% and 9.3% respectively; whereas the +40% and +60% treatments significantly increased GEP, ER, and NEE by 18.0%, 23.5%, 15.4%, 19.4%, 22.1%, and 29.0% respectively. Moreover, the observed positive asymmetry in ecosystem carbon flux arose because, under reduced precipitation, vegetation coverage and total biomass were less affected by high soil salinity. Additionally, plants coverage responded differently to flooding under precipitation treatments: saline plants were most affected under reduced precipitation, while gramineous plants showed no significant difference.
