Summary: Marine vegetated habitats, such as seagrass, mangroves, and macroalgae, provide important habitats for a diversity of fish species, including juvenile and commercially important fish found on coral reefs. This study evaluated the habitat associations of fish species in different vegetated habitats in the Red Sea and found that coral reef fish species utilized macroalgae and seagrass more than mangroves. These habitats offer different combinations of resources, suggesting that a mix of these habitats could support biodiversity and connectivity across the seascape.

Summary: An investigation was conducted on the occurrence of Psychrobacter glacincola infection in wild marine fishes from the Red sea in Hurghada, Egypt. The prevalence rate of the disease was found to be 6.7%. The recovered isolates were identified as P. glacincola through biochemical and molecular methods, and their pathogenicity and antibiotic sensitivity were studied. Clinical examination of the infected fish revealed various signs and postmortem examination showed congestion of internal organs. The findings contribute to our understanding of pathogenic P. glacincola infection in Egyptian marine fishes.

Summary: Continuous release of highly toxic triphenyltin compounds (TPT) from antifouling paints and fungicides has caused serious pollution to urbanized coastal marine environments worldwide since the 1960s. This study investigated the distribution profile of TPT in various tissues of marine teleost fish species collected from Hong Kong waters, revealing a positive correlation between TPT concentrations and protein contents in tissues. Muscle tissues were found to contribute most to the total TPT body burden in the fish, making the average TPT concentration in dorsal and ventral muscles a good predictor for estimating TPT burden. Further investigations should adopt similar modeling approaches to estimate the total TPT body burden in individual fish.

Summary: Most animals need to be vigilant for predators, but group-living animals can benefit from shared vigilance efforts. This study suggests that measuring an animal's blinking rate can provide a meaningful measure of vigilance. The study on captive red deer shows that as group size increases, individuals increase their blink rate, confirming the prediction that vigilance decreases.

Summary: This study investigates the impact of tropicalisation on functional niches for fishes in shallow reefs in Japan and Australia. The researchers find that functional niches in transitional communities are invaded by tropical species at different times, with habitat availability playing a more important role than competition with resident temperate species. The invasion of tropical species into temperate ecosystems indicates the need to understand and manage marine community transformation.

Summary: The stoichiometric coupling between carbon and limiting nutrients in marine phytoplankton is controlled by nitrogen availability and temperature, with different biological mechanisms involved depending on the region and spatiotemporal scale. Nitrogen availability below 40 degrees N predominantly drives phytoplankton C:N stoichiometry, while temperature and grazing pressure dominate at higher latitudes.

Summary: The study analyzed the bioaccumulation of twelve elements in tissues of 30 marine fish species collected from three fishing harbours in Mumbai, India. The results showed increased activity of oxidative stress enzymes, cellular biomarkers, and neurotransmitter enzymes, as well as inhibition of acetylcholine esterase due to pollution in muscle and brain tissues. This suggests that biochemical attributes can be reliable biomarkers for monitoring contaminated marine ecosystems even at low concentrations.

Summary: Understanding the consequences of hybridization on thermotolerance in swordtail fish, this study identified a complex architecture of thermotolerance in hybrids. It revealed a genomic region contributing to reduced thermotolerance in hybrids and widespread misexpression of genes involved in thermal stress response, particularly in the circadian clock pathway. The study also showed that hybrid incompatibility between different swordtail fish species contributed to reduced thermotolerance. These findings highlight the challenges of studying the impact of hybridization on complex ecological traits and its potential impact on adaptive introgression.

Summary: The study investigates the variation of predator-prey mass ratios (PPMR) across different taxa and body sizes, which has significant implications for ecosystem structure, function, and modeling. The findings indicate that different predator species demonstrate varying abilities in transitioning across size-structured prey taxa, leading to differences in their size-PPMR relationship. Incorporating taxon-specific PPMR size dependency in multispecies size-based ecosystem models is suggested to enhance model realism and trophic transfer efficiency.

Summary: The study found that the yellow black-headed triplefin tended to keep a greater distance from a visible black scorpionfish predator, and bobbing behavior was more frequent in its presence. However, fin-flicking behavior was equally exhibited towards all stimuli and decreased over time, suggesting the fish becoming more comfortable in the environment. The findings indicate that bobbing and fin-flicking are not exclusive pursuit-deterrent behaviors in this species, but may serve additional functions such as enhancing depth perception or signaling vigilance.

Summary: Seahorses have a global distribution in tropical to temperate coastal waters and show many adaptations for a sedentary, cryptic lifestyle. New genome assembly and re-sequenced genomes of 21 other species shed light on the evolutionary origin and global dispersal routes of seahorses, revealing that rafting via ocean currents compensates for poor dispersal and bony spines likely evolved multiple times through independent substitutions in a key developmental gene.

Summary: With over 18,000 species, Acanthomorpha fishes form the largest and most diverse radiation of vertebrates, with their evolutionary success attributed to the spiny rays in their fins. By studying the differentiation of fin domains in Astatotilapia burtoni, researchers identified distinct transcription factor signatures and mechanisms such as BMP inhibition and shh secretion that contribute to the establishment of spiny and soft-ray domains. This research suggests a repeated exaptation of developmental programs contributing to the convergent evolution of spiny fin elements in fishes.

Summary: Male pregnancy in syngnathid species, ranging from basic attachment to specialized internal gestation, offers a unique opportunity to study the evolution of pregnancy. By comparing gene expression in different stages of pregnancy, this study found that metabolic processes and immune dynamics defined pregnancy stages across species, especially in pouched species resembling female pregnancy. The regulation of immune response in pouched species supports the role of immune modulation in the evolutionary establishment of pregnancy.

Summary: This study provides a comprehensive description of the development of three syngnathid fish species and explores the origins and evolution of their body morphology. The results suggest that the convergent phenotypes in pipefishes and seahorses may have different ontogenetic means, and the characteristic features of seahorse body plan could result from developmental truncation.

Summary: The study reveals the association between male pregnancy in seahorses and specific immunological adaptations. Amino acid replacement in the tlx1 transcription factor is linked to asplenia in seahorses, indicating the loss of spleen is related to the immune system. Comparative genomics also suggests that the complexity of immune system gene repertoire decreases as parental care intensity increases.

Summary: Evolutionary novelties can promote ecological specialization and adaptive radiations. Belonoid fishes, such as flying fishes, halfbeaks, and needlefishes, have highly diversified elongated jaw phenotypes. In this study, the development of elongated jaws in a halfbeak and a needlefish was investigated, revealing that these jaws consist of distinct base and extension portions. The growth dynamics of both bases and extensions were described, and the molecular mechanisms underlying the extension outgrowth were deduced.
