Summary: Texas tomato production is vulnerable to extreme heat in the spring-summer cropping period, and the lack of superior genetic materials exacerbates this issue. Therefore, there is a need to select superior varieties that can perform well in warm environments and exhibit high yield stability under heat stress conditions. This research aimed at identifying heat-tolerant varieties through controlled and open-field environments in three stages.

Summary: Vegetation plays a crucial role in marsh ecosystems, providing nesting and foraging sites for waterfowl. The Jilin Momoge National Nature Reserve, located in northeast China, is an important stopover site for the critically endangered Siberian Crane. This research examines the response of vegetation patterns to climate change and human activities in the reserve. Analysis of vegetation cover data from 1984 to 2020 reveals that human activities have contributed significantly to vegetation improvement, while precipitation has a greater impact on vegetation growth than temperature.

Summary: Groundwater is a strategic water supply source in arid and semi-arid coastal regions, but growing demand and scarce water sources may lead to pressure on this resource and degrade water quality. A sustainable management model is developed to address these concerns, considering groundwater quality, economic efficiency, and social inclusion. The model is solved using simulation-based optimization and three evolutionary algorithms, with NSGA-II performing the best in terms of solution quality.

Summary: This study used a modified algorithm to extract LSP metrics from MODIS data in arid and semi-arid regions of Australia, improving the spatial extent of LSP retrievals. The results revealed that vegetation growth in these ecosystems is highly irregular and can occur at any time, with a correlation to annual precipitation.

Summary: This study developed and evaluated machine learning algorithms for estimating daily maize crop evapotranspiration in semi-arid conditions using limited weather variables. Five algorithms were examined and it was found that the category boosting and artificial neural network models were superior during training, while the support vector machine and artificial neural network models were excellent during testing. Wind speed was found to be the most influential variable in evapotranspiration estimation. The SVM and ANN models produced promising results with high accuracy, making them suitable for precise estimation of evapotranspiration in a semi-arid climate.

Summary: The hyperuniformity of vegetation Turing patterns is related to water-use efficiency. Near the tipping point, Turing-type ecosystems exhibit significant critical slowing down, indicating non-negligible transient dynamical behavior. Reduced rainfall affects both the resilience of the ecosystem's steady state and the rate of spatial optimization of water-use efficiency in long transient regimes. The degree of hyperuniformity can be used to assess the spatial resilience of ecosystems after disturbances.

Summary: Peru, a megadiverse country, displays a great diversity of ecosystems due to its tropical location, marine currents, and complex relief. Arid and semi-arid ecosystems cover a significant portion of the Peruvian territory and are home to a variety of aquatic macroinvertebrates. Research on aquatic macroinvertebrates in Peru has increased in recent years, focusing on bioindication, biodiversity, taxonomy, and distribution, with rivers being the most intensively studied ecosystems. Further studies are recommended to explore the taxonomic and ecological aspects of macroinvertebrates, especially in the eastern slope, and to calibrate biotic indices for main hydrographic basins.

Summary: This study examines the effectiveness of adaptation measures for rural communities in arid and semi-arid regions facing climate variability and change, finding that integrated adaptation measures are most likely to enhance resilience. Inclusive institutions, financial assistance, and climate information services are needed to facilitate such adaptation measures.

Summary: This study aimed to define and compare the morphometrics features in body size and wing shape of Triatoma guasayana in relation to temperature and rainfall. The results showed that the wing morphology of T. guasayana has phenotypic plasticity and is correlated with temperature and precipitation. Furthermore, there are differences in body size and wing shape between males and females.

Summary: This study presents a remote sensing-based approach to assess the potential of groundwater dependent ecosystems (GDEs) by analyzing the persistency of vegetation parameters during dry periods. The approach was successfully applied in the semi-arid Flinders Ranges of South Australia to identify areas with high or low potential for groundwater resources.

Summary: Soil erosion is influenced by observation scale and soil surface conditions. At larger scales, soil loss increases significantly, highlighting the scale effect. Additionally, soil surface conditions have a significant impact on soil erosion, with higher soil loss occurring on barren and degraded soils.

Summary: The objective of this study was to assess the effectiveness of Sentinel-2A (MultiSpectral Instrument, MSI) and Landsat (Operational Land Imager, OLI and Thermal Infrared Sensor, TIRS) derived indices in detecting small-extent forest fires and severity degrees. Sentinel-2 performed better than Landsat-8 in accurately delimiting the fire perimeter and detecting the burned area. The dNBR index showed higher accuracy in detecting fire severity degrees compared to dNDVI and dTST. However, further remote sensing techniques, such as Landsat-Sentinel data fusion, are needed to improve the potential for separating fire severity.

Summary: This study investigated the spatial variation characteristics and driving factors of dissolved organic matter (DOM) in vegetation-restored ephemeral gullies (EGs) in a typical semi-arid region. The results showed that DOM content and composition varied along the EGs, primarily influenced by biocrusts, plant litter, and roots.
