Summary: This study analyzed the secreted liquid of salt glands and identified that vesicle transport proteins and energy metabolism-related proteins play a significant role in salt secretion. The findings suggest that trans-Golgi network-mediated vesicular transport and energy production contribute to salt secretion in salt glands.

Summary: In this study, LbMYB48 gene was found to be induced by salt stress in Limonium bicolor, and it regulates the development of salt glands and salt tolerance by modulating the expression of genes related to salt gland development and salt stress response. Heterologous over-expression of LbMYB48 in Arabidopsis thaliana enhances salt tolerance through stabilizing ion and osmotic balance.

Summary: Soil salinization is a serious global issue, but some plants can grow on saline-alkali soil by secreting excessive salt out of their bodies. Previous hypotheses explained the salt secretion process, but recent studies show that vesicular transport plays a vital role in this process.

Summary: The study investigated the salinity thresholds of four Limonium species and found that total dry weight, chlorophyll content, and intercellular CO2 concentration were highly correlated with total fresh weights, serving as indicators of plant salt tolerance. Salt gland density, Na+ content, and Na+ secretion rate per salt gland were positively correlated with salt concentration, highlighting the importance of salt glands in adapting Limonium species to high salinity conditions.

Summary: This review summarizes the recent progress in understanding the development and operation mechanisms of salt bladders and glands at physiological, molecular, and genetic levels. The processes differ depending on the anatomical structure and types of salt glands. Evidence for the role of vesicular transport and the importance of multi-omics in salt secretion and tolerance are discussed.

Summary: The study found that high salt intake significantly increased blood pressure and exacerbated renal injury in salt-sensitive rats, while salt-resistant rats showed less severe symptoms. In consomic rats, high salt intake significantly decreased renal vascular resistance and increased renal blood flow, whereas these changes did not occur in salt-sensitive rats.

Summary: Hematopoietic stem and progenitor cells maintain blood cell homeostasis by integrating mechanical cues from the vascular niche. Mechanical forces are transduced by the Piezo channel, leading to activation of Notch pathway and repression of FGF signaling, which regulate hematopoietic progenitor maintenance.

Summary: Anopheles merus, a malaria-transmitting mosquito, has the ability to breed in saltwater. This study examined the consequences of breeding in different saltwater concentrations on the life history of An. merus. The findings suggest that high salt concentrations delay larval development, increase insecticide tolerance, and affect the composition of gut microbiota. These changes may have epidemiological implications for the transmission of malaria.

Summary: In this study, a transmembrane protein called LbRSG was found to play a positive role in salt gland development and salt secretion in the recretohalophyte Limonium bicolor. The highly negatively charged regions in the extramembrane loop were identified to be important for salt tolerance. Additionally, the interaction of LbRSG with PGK1 and BGLU18 was proposed to enhance salt tolerance in salt glands.

Summary: This study used animal telemetry to analyze the social behaviors of estuarine crocodiles in the wild, revealing that they are more social than previously thought. The individual's sex, degree of site-fidelity, and proximity to the mating season influenced the spatial overlap between potential mates and conspecifics.

Summary: This study examines the effects of acute ultraviolet-B radiation (UVBR) exposure during early life stages on amphibian population dynamics. The results indicate that higher doses of UVBR exposure in tadpoles lead to faster metamorphosis, but result in smaller size and poorer condition in the resulting frogs. Additionally, the study provides empirical evidence of UVBR-induced telomere shortening, which may contribute to life-history trade-offs and post-metamorphic condition.

Summary: Aquatically respiring animals exposed to low pH waters suffer inhibition of ion uptake and loss of branchial integrity. Environmental calcium levels are pivotal in maintaining branchial junction integrity, with supplemental calcium reversing the negative effects of low pH in some animals. The mechanism by which animals overcome the damaging actions of low pH and low environmental calcium levels remains unknown. This study examined the effects of environmental calcium levels on the response to low pH in acid-tolerant frog larvae. It was found that additional calcium improved resistance to sodium efflux at low pH, and the expression of a calcium transport protein played a role in the acid tolerance of the larvae.

Summary: Increasing drought frequency and duration pose a significant threat to fish species in dryland river systems. This study found that body size significantly affects the thermal and hypoxia tolerances of fish, with smaller fish being less hypoxia tolerant and larger fish being less thermal tolerant. The results suggest that both very small and very large fish in dryland rivers are at significant risk from the combined impacts of a warming and drying climate and water extraction.

Summary: Animal social systems are dynamic and influenced by changes in population demography and resource availability. This study investigated the social organization and connectivity of a wild population of estuarine crocodiles based on a 10-year telemetry data set. Results showed that these crocodiles formed spatially segregated communities along a river and estuary, with social structure and organization being temporally dynamic. The proximity to the mating season and an individual's maturity status influenced the associations among conspecifics.

Summary: In species with costly conflict, individuals use alternative movement tactics to minimize competitive interactions. This study investigated how the behavior of male estuarine crocodiles shifted over an 11-year period in relation to ontogeny, body condition, and physical injuries. Results showed that males sorted into different movement classes, with larger males maintaining confined territories, while smaller males adopted high movement or low movement tactics. Our study provides insights into the mechanisms and costs of movement tactics in wild crocodile populations.

Summary: Ecological carryover effects refer to the delayed effects of the environment on an organism's phenotype, which have significant impacts on individual fitness and are important in conservation biology. Climate change introduces more variable environmental conditions that can negatively affect early life stages of animals with complex life histories, leading to physiological and fitness consequences later in life. However, due to the latent nature and long temporal scales of carryover effects, this phenomenon is often understudied and overlooked in short-term studies.

Summary: Ultraviolet radiation (UVR) from the sun affects the physiology of vertebrates, with fish and amphibians being the most susceptible taxa. Adult and larvae life stages are also more vulnerable to UVR stress. Animals inhabiting temperate and tropical latitudes are the most susceptible to UVR stress. Understanding the effects of UVR on vertebrates is important for conservation and mitigation strategies.

Summary: Anthropogenic ozone depletion has led to an increase in UVBR levels reaching the earth's surface, causing harmful DNA damage in amphibians. The repair response to UVBR and temperature varies among different amphibian species. This research emphasizes the importance of considering species-specific physiology when predicting the effects of changing UVBR and temperature in aquatic ecosystems.
