Summary: Droughts are projected to increase in magnitude, frequency and duration in the near future. This study found that arid and semi-arid rangelands are more severely impacted by drought in terms of forage provision compared to mesic rangelands. The negative impact on forage productivity in these rangelands is mainly driven by the reduction in productivity of key plant species.

Summary: The research identified Ziziphus nummularia (CIAHZN-J) as the most drought-tolerant ecotype, displaying characteristics such as increased membrane stability, root length and number, proline content, catalase and sugar content. It maintained growth under drought stress and activated genes involved in sugar metabolism, abscisic acid biosynthesis, osmoregulation, and reactive oxygen species homeostasis. Their findings suggest that CIAHZN-J is a valuable genetic resource for studying drought-responsive genes and improving crop drought tolerance.

Summary: A framework was established to monitor drought in the semi-arid regions of eastern Tamil Nadu, India, from 2014 to 2018 using various drought indices. The study found negative precipitation anomalies, vegetative stress, and significant losses in the farming sector due to meteorological and agricultural droughts. The most extreme drought impacts were observed in the eastern region, followed by the northern and southern regions. The socio-economic vulnerability of the eastern region, characterized by a higher population and household density, hampers its ability to overcome droughts.

Summary: In this study, GRACE satellite data was used to quantify drought severity by analyzing land terrestrial water storage changes. The water storage deficit and water storage deficit index were used to identify drought events and evaluate their severity. The results showed that there were a total of 22 drought events in the central Asian dry zone, with spring and autumn experiencing more frequent and severe droughts. The longest and most severe drought occurred near the Caspian Sea. The study also found that the north of the arid area tended to be moist, while the south, east, and Caspian Sea area tended to be drier.

Summary: Based on climate data from 1999 to 2020, it was found that the precipitation during different growth stages of winter wheat in the Huai river region of China is unevenly distributed. The critical periods of jointing and booting have less precipitation, while the heading-filling and maturation stages have a large fluctuation range of precipitation, leading to the risk of flood and drought. These findings provide a foundation for guiding winter wheat cropping in the region.

Summary: Ecosystems with forest and grassland patches as alternative stable states contain various habitats aligned along a vegetation cover gradient, showing different patterns of taxonomic, functional, and phylogenetic diversity. Taxonomic diversity peaks in the middle of the gradient, functional diversity is high in woody habitats but lower in grassland, and phylogenetic diversity varies depending on the evolutionary age of the habitats. The community assembly in grasslands may be dominated by environmental filtering, while competition may be decisive in woody habitats.

Summary: The onion thrips, Thrips tabaci Lindeman, is a complex species consisting of three distinct lineages. This study aimed to investigate the morphometric variation and distinguishable characters among these lineages. Significant differences in egg size were observed, and adult females of one lineage showed better separation than first instar larvae. Moreover, the sexual dimorphism in adult size may not be influenced by egg and larval size.

Summary: Plant litter decomposition is a crucial ecosystem process affected by climate change. Besides the direct effects of drought, the indirect effects caused by various drought-induced changes should also be considered. A study found that prolonged drought led to reduced mass loss in plant litter. Leaves decomposed faster than roots, and Festuca vaginata decomposed faster than Stipa borysthenica. Additionally, deep soil had a higher decomposition rate compared to shallow soil.

Summary: Intercropping is a known agroecological method for suppressing weeds by growing multiple crops together in the same area. Cereal-legume intercropping systems are important for increasing biodiversity in arable lands, as cereals provide physical support to legumes and enhance weed suppression. Our research aimed to determine the weed composition and cover in different crops and intercropping systems, and found that intercropping reduces the need for herbicides and promotes more sustainable and effective weed management.

Summary: The present study aims to investigate and model the dealcoholization process of pale lager beer through reverse osmosis (RO). Dealcoholization experiments were conducted at a temperature of 15 +/- 1 degrees C using an Alfa Laval RO99 membrane. Various analytical parameters of beer and permeate samples were measured. A 2(P) full factorial experimental design was applied to determine the effect of transmembrane pressure (TMP) and retentate flow rate (Q) on the initial ethanol flux (J(EtOH 0)). The optimization process revealed that TMP had a significant effect on J(EtOH 0) with an effect size of 1.20, and the optimal TMP value was found to be 30 bar. The predicted J(EtOH 0) under these conditions was 121.965 g/m(2) h.

Summary: The microencapsulation of extra virgin olive oil was studied by preparing emulsions using different proportions of maltodextrin and whey protein isolates, followed by dehydration using spray-drying or freeze-drying methods. The characteristics of the microcapsules were influenced by emulsion stability, viscosity, and droplet size. The highest encapsulation efficiency was achieved with 50% maltodextrin and 50% whey protein isolate in the emulsions, followed by spray-drying. The moisture content and size of the microcapsules increased with increasing proportions of maltodextrin and whey protein isolate, respectively. The bulk density and tapped density decreased with higher proportions of maltodextrin, and microcapsules with a higher proportion of maltodextrin exhibited poor flowability and high cohesiveness.
