Summary: This study investigated the genetic differentiation of two Istiophorid billfishes, white marlin and striped marlin. By analyzing samples from the Atlantic, Pacific, and Indian oceans, it was found that white marlin and striped marlin have significant genetic differentiation and can be considered as separate species. The divergence time between them is estimated to be approximately 2.38 million years ago.

Summary: This report provides the first confirmed identifications of wahoo and striped marlin in the Red Sea, expanding their known ranges. The potential mechanisms for the lack of regional documentation of these species are discussed. These findings highlight the need for systematic biodiversity surveys of pelagic fish in the Red Sea.

Summary: This study utilized movement patterns from a multidecadal tagging dataset to create monthly distribution maps for Atlantic bluefin tuna, separating catch records into stock-specific catch time series. The research identified an increase in catch proportion from the eastern stock over the past two decades, attributed to a decrease in CPUE in regions dominated by the western stock.

Summary: The study described the reproductive biology of white marlin in the Atlantic Ocean, finding a higher reproductive activity in the third quarter of the year for females, and estimated the 50% maturity length for females and males at 145.04 cm and 140.03 cm respectively using a Bayesian logistic model approach.

Summary: This study reconstructed the growth variation of European sprat in the Baltic Sea from 1956 to 2020 using archived otoliths, and identified significant negative relationships between sprat growth, sprat spawning stock biomass (SSB), and water salinity. By estimating SSB based on otolith-derived growth information, this study demonstrates the potential of otolith-based biochronology for providing independent indices of historical fish stock size.

Summary: The study extensively reviewed the life-history traits of Pacific and Atlantic herring populations, finding that body size of Pacific herring increased with latitude, while the pattern was inconsistent for Atlantic herring. Atlantic herring summer and autumn spawners produced many small eggs compared to spring spawners, aligning with findings from decades ago.

Summary: Climate change has diverse effects on populations, with variations in response across different populations and life stages. An experimental study on mole salamanders found that a slight increase in temperature during larval development had complex consequences, including density-dependent effects on growth and body mass, density-independent effects on fat storage, and no effects on survival and reproductive investment. Although warming reduced growth rates, size at maturity, and fat storage, it did not significantly impact survival and reproductive investment in the first year. However, smaller body size and lower fat reserves may limit overwintering survival and future reproduction.

Summary: Genome size is proposed to influence extinction risk, but our global-scale analysis using amphibians as a model shows no support for this hypothesis. The only consistent predictor of extinction risk is decreasing geographical range size.

Summary: Predator-induced plasticity is an adaptive response in prey to predation risks. This study compares the predator-induced plasticity of Daphnia against size-selective predators and shows that body size is a key trait influencing its plasticity expression and evolution.

Summary: The evolution of internal fertilization has reshaped sexual selection and the covariances among sexual traits. It is unclear whether fertilization mode also shows evolutionary associations with traits other than primary sex traits. Using a phylogenetically controlled approach, the study found that external fertilizers are consistently larger than internal fertilizers within all phyla.

Summary: The digitization and open availability of life history traits measured directly from individuals provide a key means of linking organismal function to environmental and ecological contexts at fine resolution. In this study, we use digitized museum specimen and census data to investigate the impact of climate and body size on litter size in 39 small mammals across North America. Our findings show that both climate and body size have significant influences on litter size, with body size being the stronger factor. The individual-level biodiversity records improve the precision and granularity of ecological studies and contribute to a better understanding of tradeoffs between energetic supply and demand in wild mammals.

Summary: Bats' reproductive success, especially for young females, is significantly affected by increased precipitation during a short time window in spring. Additionally, larger females have higher reproductive success.

Summary: Research suggests that there may not be a trade-off between brain size and life-history pace in killifish, as fast-living species have larger relative brain sizes in adulthood compared to slow-living species. This discrepancy could potentially be due to differences in the timing of somatic versus neural growth or cognitive demands in their respective environments.

Summary: This study investigated the influence of paternal life-history form and egg size on offspring life-history traits in masu salmon. The results showed that egg size was related to early-life body size of the offspring, while paternal life-history form had no effect. Additionally, the study found that the movement of offspring within the tributary differed between males and females, but was not influenced by egg size or paternal life-history form. The researchers concluded that environmental conditions play a more significant role than parental genetic effects in shaping offspring life-history traits.

Summary: A 35-year cod growth chronology was reconstructed using sclerochronology techniques, showing a decrease in cod growth over time possibly due to climate variability and anthropogenic pressures. The study also identified different drivers of cod growth in different periods.

Summary: This study found that jaw length is an important predictor of trophic position in fishes, while body mass has a weak relationship with trophic position. Trophic position is not always positively correlated with body mass globally, and in some cases, a negative correlation was observed.

Differences in behavioral responses were observed between wild and hatchery fish. Parasite infection, fish source, and parasite type were identified as factors that could affect fish behavior.

Summary: A study revealed that there is a high chance of extinction for 9 highly imperilled species within the next 20 years in Australia, with over 50% likelihood. Additionally, there are 16 species considered to be extant under Australian legislation that have over 50% probability of already being extinct. Most of these species occur within conservation areas in south-eastern Australia, where human population density is highest.

Summary: This study compared the individual behavior of hatchery-reared and wild Murray cod, as well as invasive common carp. The results showed that hatchery-reared cod and invasive carp displayed bolder behaviors compared to wild cod. However, there was a difference in their response to predators, with hatchery-reared cod staying near predators while carp rapidly escaped.

Summary: Wild silver perch in Australia were found to be infected with digenean mesocercaria in their head tissues. It is uncertain whether these mesocercaria represent a new species or an already described species due to the lack of comparable sequences. However, the presence of digenean mesocercaria in the critically endangered silver perch population is of potential conservation significance.

Summary: This study explores the dietary changes of estuarine crocodiles during their population recovery. The results show that contemporary crocodiles have a preference for terrestrial food sources rather than marine ones, possibly due to increased competition and a higher abundance of feral ungulates. The study also reveals that the consumption of feral pigs by crocodiles helps control pig population growth and increase the flow of terrestrially derived nutrients into aquatic ecosystems.
