Summary: This study evaluated the effects of water-soluble 17 beta estradiol exposure on the external morphology of Bluegill, showing changes in male dimorphic characters and morphological structure. These changes could potentially impact reproductive success and mate selection in fish populations.

Summary: This study investigated how different male reproductive morphotypes of bluegill sunfish contribute to the patterns of infection by strigeid trematodes. The results showed that alpha-males had greater infection abundance and different infection locations compared to females and beta-males. These differences may be due to increased nesting responsibilities and potential interaction with snail intermediate hosts.

Summary: The study found that exposure to predator kairomones can elicit bolder and more exploratory behaviors in juvenile bluegill. The relationship between cognitive ability and boldness and exploration behaviors is still unclear and requires further investigation. This suggests that ecological and evolutionary pressures, as well as intrinsic factors, may influence the behavioral responses of animals to different stimuli.

Summary: This study presents a chromosome-scale genome assembly of the Bluegill (Lepomis macrochirus), which is a member of the Centrarchidae family of North American sunfishes. The assembly was generated using a combination of long-read and short-insert sequencing data, and it provides valuable genetic information for future studies on the evolutionary history of centrarchids.

Summary: This study used micro-computed tomography to determine the locations of the center of mass (COM) and center of buoyancy (COB) in bluegill sunfish. The findings showed a small but significant difference between the locations of COM and COB, which can be influenced by the shape and centroid location of the swim bladder. The swim bladder volume, however, did not show any correlation with the distance between COM and COB.

Summary: Long-term elevation of cortisol in teleost fishes as a stress response may have detrimental effects on health and physiological performance. However, a study on bluegill sunfish showed no measurable effect of cortisol on exploratory behavior.

Summary: This study establishes Hydractinia as a reliable non-bilaterian model system for the study of sex determination and the evolution of sex chromosomes. By generating a linkage map and utilizing deep sequencing, the researchers found pseudoautosomal and non-recombining regions on the X and Y chromosomes of Hydractinia. They also identified genes in the non-recombining region that are specifically expressed in the male gonad. Additionally, the study observed enhanced recombination rates in the female genome and determined that Hydractinia has a haploid chromosome number of n = 15.

Summary: This study explores the kinematic and dynamic characteristics of Misgurnus anguillicaudatus during turning maneuvers, providing insights into the propulsion mechanism of aquatic organisms and guiding the design of fish-like propulsion devices. The results reveal the formation of vortices and jets, with suction dominating the thrust mechanism. The study also introduces the use of proper orthogonal decomposition for noise filtering and flow field reconstruction.

Summary: In fishes, damage to important morphological structures such as fins can have cascading effects on prey capture performance and individual fitness. This study examined the effect of sub-lethal fin damage on bluegill sunfish and found that damaged fish exhibited lower stability and consistency in kinematics, which could impact higher-order ecological interactions.

Summary: This study aimed to determine the importance of QTL monitoring and QTL inter loci interaction in safflower under normal and drought stress conditions. A new linkage map with 69 polymorphic AFLP markers was constructed, identifying 17 major QTL and 66 epistatic QTL for ten agronomic traits. These QTL accounted for 3.04%-24.71% and 8.31%-56.5% of the phenotypic variations of traits, respectively. Seven main genomic regions on linkage group (LG) 4 and LG5 were found to co-localize QTL for various traits, providing valuable information for future breeding programs to enhance drought tolerance.

Summary: The study developed high-density SSR genetic linkage maps for sweet potato, consisting of 90 linkage groups and 15 homologous groups, which are consistent with the autohexaploid nature of sweetpotato. These maps provide a foundation for QTL mapping, marker-assisted breeding, and comparative genomics research of sweet potato.
