Summary: Freshwater fish populations are declining globally, and many small Australian fish species may face extinction within the next twenty years. Cryopreservation of reproductive cells and tissues allows for the possibility of reproducing individuals even after a species becomes extinct in the wild. Researchers have successfully developed a cryopreservation protocol for the ovarian tissue of the Murray River Rainbowfish, which can serve as a model for the conservation of other fish species in Australia and worldwide.

Summary: As information ages, it becomes less accurate and increases uncertainty for decision makers. This study explores how the uncertainty associated with older information affects the retention of learned responses. The results show that wood frog tadpoles can learn to recognize predators based on aged chemical alarm cues, but only those conditioned with fresh cues retain this learned response in the long term.

Summary: In degraded coral reef environments, Whitetail damselfish are able to learn to classify Moonwrasse as a non-predator through latent inhibition, but this recognition is dramatically altered in dead coral habitats. Changing background odors in different water sources pose a cognitive challenge for prey to learn non-predator identities separately, with significant survival consequences in a changing environment.

Summary: This study found that both Shoshone pupfish and Amargosa River pupfish respond to conspecific chemical alarm cues by reducing activity and changing their vertical position in the water column. The experiments also demonstrated that pupfish can recognize a novel predator through exposure to epidermal alarm cues, which is the first report of acquired predator recognition in pupfish. These findings have potential implications for the management and conservation of endangered desert fishes.

Summary: Invasive species pose a threat to biodiversity and ecosystem functioning. Researchers have used an innovative experimental approach to show that brief exposure to a robotic predator alters mosquitofish behavior, increasing fear and stress responses, and mitigates its impact on native tadpoles. The effects of predation risk from the robot persist for weeks, resulting in weight loss, body shape variation, and reduced fertility in mosquitofish.

Summary: Early exposure to familiar sounds can shape social behaviors in birds, with different chronic acoustic playbacks altering genome-wide methylation. Immediate early gene activation in response to different types of songs is negatively correlated with methylation extent, indicating a neuroepigenomic mechanism for the impacts of early acoustic experiences in songbirds.

Summary: This study assessed the consistency of different methodologies in investigating lateralisation in fish and found that detour assays produced consistent results in terms of relative lateralisation, but differed in terms of absolute laterality. The mirror maze assay did not show any similarity to the detour assays. Additionally, the study found that reducing the number of turns in a detour assay exaggerated lateralisation indexes. The results suggest the need to increase the number of observed turning choices to minimize the influence of random chance or external factors on lateralisation indexes.

Summary: A study found that ectothermic marine species exhibit allometric scaling for activity space, although the relationship is weaker compared to terrestrial species. Body mass alone can only explain 35% of the variation, with trophic position and latitude being stronger predictors for marine species. The study highlights the importance of using large-scale animal biotelemetry networks to address evolutionary and ecological questions across different taxa.

Summary: 450 million years of evolution have allowed chondrichthyans to adapt to their everyday life challenges and cognitive abilities have played a vital role in that process. Recent cognitive assessments suggest that sharks and rays are on par with most other vertebrates in terms of cognition. While advancements have been made in understanding their behavior, the underlying neural substrates involved in cognitive information processing remain largely unknown. Understanding shark cognition has practical benefits for welfare and conservation management, but gaps in knowledge still exist.

Summary: Using stable-isotope analysis and acoustic telemetry, researchers identified different movement strategies and habitat selection in Port Jackson sharks. Migrating males and females may utilize different geographical areas or niches during the non-breeding season. These variable movement strategies may have different reproductive fitness advantages on an individual and population level, with implications for the broader marine ecosystem.

Summary: The study explores the threat of translocating species on freshwater fish biodiversity and presents a successful case of conserving Running River rainbowfish. By captive-breeding wild fish and translocating them to unoccupied habitats, two populations of Running River rainbowfish were established, but challenges of predation and release timing remain. This provides valuable insights for similar conservation programs involving short-lived fish species.

Summary: Several factors, such as hormones and light exposure, affect the development of lateralization. The study manipulated laterality by exposing embryos to light or darkness and examined the association between a shift in laterality and behavior in a novel environment test. It was found that light exposure influenced early development of laterality, but this bias was lost by 3 months of age. The study suggests that light exposure during early development can influence laterality and provides a useful tool for future research on the causes and consequences of laterality.
