Summary: This study investigates the impact of bruise damage, storage temperature, and storage period on the physiological responses of Omani pomegranate fruit. The results show that bruise area, bruise volume, and bruise susceptibility increased with higher impact levels, longer storage duration, and higher storage temperature. Moreover, high impact and higher storage temperature led to significant weight loss, reduced firmness, and decreased geometric mean diameter. The study also found that lightness, yellowness, browning index decreased, and redness increased over time due to impact bruising level and storage temperature. Furthermore, respiration rate and ethylene production rate increased with higher impact levels and storage temperature. Therefore, it is important to handle and store fresh produce carefully to avoid mechanical damage and quality losses.

Summary: This study used climatic data from different years and experiments conducted in Nebraska to estimate comfort thermal indices and predict the risk of heat stress. The results showed correlations between tympanic temperature (TT) and THIPST and THIadj, as well as correlations between respiration rate (RR) and THI, THIadj, and HLI. Thermal comfort indices were positively correlated with TT, especially THIPST. However, weak relationships were observed between thermal indices and RR, confirming the different roles of TT and RR as heat stress indicators. THIPST was found to be the best index for predicting TT.

Summary: In this study, top-suction forced-air precooling (FC) was used to rapidly remove field heat from winged bean pods, and its effects on pod storage quality and shelf life were evaluated. The results showed that FC was significantly faster than room cooling (RC) in terms of precooling time and had a lower weight loss rate. FC also delayed decay and significantly extended the shelf life of winged bean pods compared to RC. In conclusion, FC is an effective method for rapid postharvest field heat removal and maintenance of winged bean storage quality.

Summary: In 2011-2013, the interactive effects of cerambycid pheromones on trap catches of predators associated with bark and woodboring beetles were studied in north Georgia and South Carolina. Different predators, such as T. virescens, C. pilosa, and A. crassipes, were attracted to traps baited with specific pheromones, and the presence of ethanol enhanced the attraction of T. virescens. Furthermore, the response profiles of these predators were compared to gain insights into ecological interactions between them and longhorn beetles captured in the same studies.

Summary: To test the hypothesis that non-consumptive predation pressures favor genotypes with higher equilibrium densities or mictic ratios, populations of rotifer Brachionus angularis were exposed to different concentrations of predator Asplanchna kairomones. The results showed that low concentrations selected for higher equilibrium densities while high concentrations selected for higher mictic ratios. Additionally, common garden bioassays revealed that populations with low concentration selection history had higher intrinsic rate of population increase, and populations with high concentration selection history had higher mictic ratios.

Summary: This study evaluated the chilling injury symptoms in soursop fruit when stored at low temperatures. The results showed that soursops stored at 9 degrees C did not develop normal color and firmness, while those stored at 14 degrees C behaved similarly to the control group. Additionally, soursops stored at 9 degrees C for 8 days showed substantial decreases in respiration, ethylene production, electrolyte leakage, and flavonoid content, while total phenolics increased.

Summary: This study aimed to explore the differences in cardiorespiratory responses to normobaric hypoxia between men and women. The results showed that men had a more pronounced ventilatory response to hypoxia compared to women, while women experienced a faster decrease in peripheral oxygen saturation during the first few hours in hypoxia.

Summary: Cyanobacteria, as photosynthetic microorganisms, play a crucial role in energy flow within aquatic food webs by interacting with zooplankton. Despite their ability to produce toxic metabolites known as cyanotoxins, the ecological and adaptive role of these toxins remains debated. Studies have suggested that cyanotoxins may serve as a defense mechanism against herbivory by zooplankton, but their overall impact on cyanobacteria fitness is still unclear.

Summary: The optogenetic-based cardiac pacing method allows non-invasive stimulation of the cardiac muscle, producing blood flow and indirectly affecting respiration rhythm. This method is feasible in awake, freely moving mice and can be used to study the relationship between heartbeat state and animal behavior.

Summary: In this study, the potential of two omnivorous predators, the damsel bug, Nabis americoferus, and the minute pirate bug, Orius insidiosus, to control the tarnished plant bug in strawberry fields was evaluated. The results showed that N. americoferus was effective in attacking all stages of the pest and reducing its population in the field, while O. insidiosus only targeted smaller nymphs with minimal impact. These findings suggest the potential of N. americoferus for an effective biological control strategy against the tarnished plant bug.

Summary: The study found that predator cues of wolf spiders may affect spiderling antipredator behavior either through prenatal exposure or modification of the mother's behavior prior to eclosion, but mother substrate preference did not influence spiderling distribution during dispersal.

Summary: This study investigated the role of fecal shield in the predation behavior of different predators on Ophrida xanthospilota larvae. The fecal shield repelled ants but attracted stinkbugs, and different chemical extracts from the fecal shield had varied effects. The study suggests that the fecal shield can play a dual role and act as a chemical communication signal in predator-prey interactions.
