Summary: The study found that the growth of alewife and rainbow smelt in different lakes is influenced by factors such as lake volume, nutrient levels, and predator abundance, with changes in catch-per-unit-effort (CPUE) in some lakes primarily attributed to increased fish mortality. The coexistence of the invasive species alewife and the native species rainbow smelt may be related to system volume and oxythermal habitat availability.

Summary: This paper investigates the relationship between synchrony and oscillation types in a two-patch system and finds that dispersal has a significant impact on population dynamics. With low levels of dispersal, increasing synchrony drives oscillating populations towards equilibrium; with medium to high levels of dispersal, oscillations may arise from equilibrium with low levels of synchrony.

Summary: The sclerochronological approaches using fish otoliths are valuable in evaluating fish responses to environmental variations, especially in regions with limited long-term data. The study on growth patterns and chemical records of dusky grouper Epinephelus marginatus revealed the impact of environmental conditions on individual growth and otolith chemistry composition. Identifying the drivers of fish growth variations is crucial for conservation and fisheries management, as population dynamics and sustainable harvesting are closely connected to individual growth.

Summary: This study investigates the impact of pre-European Maori activities on the nursery habitats of Tamure populations in the coastal zone. By analyzing the trace element chemistry of Tamure otoliths from different time periods and locations in the Hauraki Gulf, the study reveals temporal and spatial variations in otolith chemistry concentrations. This research demonstrates the potential for using midden data to evaluate indigenous effects on inshore fisheries, as well as the importance of establishing pre-industrial baseline information from the archaeological record for coastal ecology studies.

Summary: Connectivity and population structure of Nelusetta ayraud were examined along the coast of New South Wales, Australia using otolith-based methods. Differences in elemental signatures were found between locations before capture and at different times, indicating spatial variability. However, no differences were observed in the elemental signatures of juvenile fish. Our findings suggest potential spatial structuring of the N. ayraud stock at an intermediate scale within NSW.

Summary: This study develops a generic construction that embeds a new class of quantum many-body scars, called rainbow scars, into the spectrum of an arbitrary Hamiltonian. Unlike other examples of quantum many-body scars, rainbow scars display extensive bipartite entanglement entropy and can occur multiple times or even throughout the spectrum in the presence of internal symmetries.

Summary: Despite the lack of understanding how most taxa will respond to future climate change, this research integrates genomics and environmental modeling to assess the responses of an ecologically and economically important Arctic species. The findings reveal past declines in effective population size in the Northwest Atlantic, indicating potential northward shifts and the loss of commercially important life-history variation in response to climate change. The genomic approach used here identifies both past and future declines that impact species persistence, ecosystem stability, and food security in the Arctic.

Summary: Animals actively select suitable habitat based on fitness, with temperature playing a crucial role. This study reconstructed population abundance, oxygen isotope, and temperature chronologies for Icelandic and Northeast Arctic cod populations and found that Icelandic cod migrated towards warmer waters with increasing abundance, while NEA cod moved towards colder waters. These findings suggest that thermal preferences and density-dependent effects can help predict potential redistribution scenarios of fish as oceans warm.

Summary: The study identified chromosomal rearrangements in Atlantic Salmon populations in southern Newfoundland, Canada, with a particular focus on the Ssa01/Ssa23 translocation variant which was strongly correlated with population structure and temperature. The results suggest that environmental selection acting on these structural variants introduced through secondary contact may drive fine-scale local adaptation in Placentia Bay, Newfoundland, Canada.

Summary: Teleosts exhibit extensive diversity of sex determination systems and mechanisms. In this study, the genome of the common lumpfish was sequenced and the sex determination region and master sex determination locus were identified. Anti-Mullerian hormone (AMH) was found to be the putative sex determination factor. The study provides important insights into the early evolution of sex chromosomes and has implications for lumpfish conservation and aquaculture.

Summary: This study collected a large number of fish through collaboration with the commercial fishing industry to overcome the lack of information on the life history of the U.S. Atlantic Wolffish. The study found that the Atlantic Wolffish has a long lifespan and larger males. The preliminary estimates of total mortality were lower than before the moratorium, and skip spawning was observed in a small percentage of mature females. Accounting for abortive maturation improved the precision of maturity estimates.

Summary: Large-scale climate-induced synchrony in fish populations' productivity is increasing in the world's oceans. The costs and benefits of trait synchronization, such as growth rate, depend on the context. Contrary to prevailing views, synchrony among individuals could actually be beneficial for populations, especially during favorable conditions. To study this, century-scale time series of annual otolith growth were used to test for changes in growth synchronization among individuals within multiple populations of Atlantic cod. The results showed increasing conformity in long-term growth rates within northeast Atlantic cod populations, indicating adaptive trait optimization in response to climate variability.

Summary: To combat the decline in pelagic sharks, management and conservation measures have been implemented, such as gear restrictions and no-retention policies. However, it is important to understand the prognostic factors that influence the post-release survival outcomes of discarded sharks. The study found that larger, uninjured sharks and those released with low shark length to trailing branchline ratios had higher survival rates, highlighting the need for improved handling and release practices and reduced bycatch.

Summary: The vertebrate eye lens grows by adding layers of lens fiber cells and degrading previously-deposited cells to maintain transparency. The study aimed to determine the consistent location of the gelatinous outer cortex and hardened interior of the lens in fish species, and its relationship to fiber cell morphology and function. The finding of a fixed ratio of hardened lens diameter to overall lens diameter suggests a common refractive index profile across fish taxa, and the relationship can be used to backcalculate fish length.

Summary: There is no consensus on why females prefer mates with rare phenotypes, but sexual selection can maintain genetic variation. We examined the fitness consequences of female preference for rare male color patterns in Trinidadian guppies over 10 generations and found that rare males have a reproductive advantage and mating with them gives females an indirect fitness advantage through the success of their sons. However, the fitness benefit disappears for grandsons as the rare phenotype becomes common. Contrary to prevailing theory, our study shows that female preference can be maintained through indirect selection.

Summary: This study tests the comparability of age interpretation across different time periods using an 86-year time series data. The results show that changes in otolith preparation, viewing protocol, and age reader can lead to biases in age estimates. The bias is most strongly linked to the individual age reader, and the transition from unsectioned to sectioned otoliths improves precision. The study suggests that old data sets incorporating historic age determinations can still be adequate for many research purposes.
