“…As shown in Figure C, the fluorescence intensity of ROS in the air group was relatively higher at 24 h than at 48 h. Ambekar et al reported that temperature was a key abiotic factor that affects the production of ROS. The relatively stronger fluorescence intensity at 24 h could be attributed to the sudden cold stress from the activation temperature of 30 °C to the incubation temperature of 4 °C .…”

To explore whether oxidative stress caused by 100% CO 2 is an inhibitory mechanism against Shewanella putrefaciens, the oxidative stress reaction, antioxidant activity, and damage to the cell membrane, protein, and DNA of CO 2 -incubated S. putrefaciens at 4 °C were evaluated. Research demonstrated that CO 2 caused more severe reactive oxygen species (ROS) accumulation. Simultaneously, weaker•− -scavenging activity and decreased T-VOC and GSH content were also observed. The activities of antioxidant enzymes (SOD, POD, CAT, and GPX) continuously declined, which might be attributed to the CO 2 -mediated decrease in the pH value. Correspondingly, the cell membrane was damaged with hyperpolarization, increased permeability, and more severe lipid peroxidation. The expression of total and membrane protein decreased, and the synthesis and activity of extracellular protease were inhibited. DNA was also subjected to oxidative damage and expressed at a lower level. All results collaboratively confirmed that ROS excitation and inhibition of antioxidant activity were important inhibition mechanisms of CO 2 on S. putrefaciens.

“…When S. putrefaciens were exposed to CO 2 , the reduction of pH, an important abiotic factor, led to increases in oxidative stress products and then activated the antioxidant defense system . It was apparent that the defensive system in the pure CO 2 group was not enough to scavenge H 2 O 2 and O 2 •– , and thus, the growth of S.…”

“…This morphological similarity suggests that conches can detect light using molecular components similar to those expressed by the retinal photoreceptors of cephalopods and other gastropods [11]. In invertebrates, these rhabdomeric photoreceptors tend to detect light using visual pigments containing rhodopsin [12][13][14]. Rhodopsin (RH) is a light-sensitive protein found in the membrane folds, known as rhabdoms, of the long cylindrical photoreceptor cells.…”

To improve aquaculture practices and husbandry of a variety of gastropods, including small conch species, it is necessary to study the physiological and endocrinological responses of nocturnal conches to light exposure. In this study, we investigated the effect of the light environment on Tegula rustica by exposing it to contrasting light conditions and observing histological changes in the retina and oxidative stress according to photoperiod and light wavelength. We confirmed that the pigment layer was significantly thicker in the group irradiated with light for 24 h (LL), but that its thickness did not differ significantly with light wavelength. Additionally, light wavelength changes did not cause a significant change in H2O2 concentration until 5 days after the change in the light environment. However, a significantly higher H2O2 concentration was observed in the LL test group on the eighth day compared with the other experimental groups. And a significantly higher total antioxidant capacity and malondialdehyde (MDA) were observed in the LL group on the third day compared with the other experimental groups. Our results indicate that the light environment affects the reaction of conches and that continuous light has a stronger effect on the thickness of the pigment layer than the light wavelength. In addition, continuous light irradiation induces excessive ROS and causes oxidative stress. These results can also be provided as basic data for husbandry when aquaculturing gastropods.

“…On the other hand, warmth promotes vegetation development by increasing water and nutrient intake as well as total plant growth. It is clear that plant development and soil temperature are inextricably linked [1], [2]. Therefore, accurate temperature forecasts can be very helpful in agriculture 4.0 [3].…”

The region of Beni Mellal, Morocco is heavily dependent on the agricultural sector as its primary source of income. Accurate temperature prediction in agriculture has many benefits including improved crop planning, reduced crop damage, optimized irrigation systems and more sustainable agricultural practices. By having a better understanding of the expected temperature patterns, farmers can make informed decisions on planting schedules, protect crops from extreme temperature events, and use resources more efficiently. The lack of data-driven studies in agriculture impedes the digitalization of farming and the advancement of accurate long-term temperature prediction models. This underscores the significance of research to identify the optimal machine learning models for that purpose. A 22-year time series dataset (2000-2022) is used in the study. The machine-learning model auto-regressive integrated moving average (ARIMA) and deep learning models simple recurrent neural network (SimpleRNN), gated recurrent unit (GRU), and long short-term memory (LSTM) were applied to the time series. The results are evaluated based on the mean absolute error (MAE). The findings indicate that the deep learning models outperformed the machine-learning model, with the GRU model achieving the lowest MAE.
