Summary: This study investigates the molecular mechanisms underlying the hydration and adhesiveness of eggs in endemic East Asian cyprinids during their adaptive radiation. It was found that semibuoyant eggs enhance hydration by increasing yolk protein degradation and the accumulation of Ca2+ and Mg2+ ions, while adhesive eggs improve adhesiveness and hardness of the egg envelope through the production of an adhesive layer and a unique 4th layer. Key molecular mechanisms involved in this adaptive radiation were identified.

Summary: Rivers worldwide have undergone significant anthropogenic transformations, resulting in reduced fish distribution and population status. This study focuses on the effects of different hydro-morphological pressure types on the distribution and population status of key fish species, providing a baseline for data-based conservation actions.

Summary: The study revealed varying levels of accessibility to different salmon species in intertidal wetlands, with Chum Salmon having more stable opportunities compared to Chinook Salmon and Coho Salmon. Inundation in wetlands fluctuated nonlinearly with tidal height, and fish were able to access the productive marsh edge for approximately 40-50% of the time during out-migration periods. The fish habitat opportunity index provided a realistic metric for assessing fish habitat opportunity and could aid resource managers in predicting the relative effects of restoration efforts on habitat opportunity for juvenile anadromous fishes.

Summary: In aquatic ecology studies, the visible implant elastomer (VIE) tagging technique is commonly used, but lacks refinement regarding animal welfare. A newly improved VIE tagging protocol has been introduced, emphasizing the Three Rs to enhance fish survival and welfare, quantitatively evaluated on different populations and age groups of zebrafish. This study will benefit the scientific zebrafish community and broader field, especially in considering animal welfare in tagging techniques.

Summary: A year-round study reveals that the seasonal variability has a significant impact on the concentration and bioaccumulation of THg in fish. Different fish species show variations in THg levels and bioaccumulation slopes across seasons, highlighting the importance of standardized sampling in long-term monitoring.

Summary: This study evaluates the applicability of eight pit-filling methods in high-resolution UAVLS-derived CHMs, with results showing the spike-free algorithm and GPMF to be the most effective. Vegetation types have different requirements for pit-filling, with coniferous forests requiring more.

Summary: This study identified fish gelatins in seven commercial cyprinid fishes using HPLC-MS/MS and found common and unique theoretical peptides in the collagen of different fish species. The combined use of these characteristic peptides can improve the traceability and identification accuracy and authenticity of fish gelatin.

Summary: Hybrid escape in aquaculture is common and can negatively impact indigenous species. In this study, the concept of postzygotic ecological isolation was introduced to reduce ecological risk caused by the escape of transgenic and genome edited varieties. The study highlights the importance of considering ecological adaptability in genetic containment strategies.

Summary: Management strategy evaluation (MSE) is a cutting-edge approach for testing and comparing management strategies, accounting for various uncertainties. Small pelagic fish play a vital ecological role in marine food webs, but present challenges to MSE and other evaluation methods due to their substantial ecological and life history uncertainties.

Summary: Passive Integrated Transponder (PIT) tags have been widely used in aquaculture selective breeding programs. This study compares the effects of PIT tagging on different size fingerlings of genetically improved Indian Major Carps (IMCs), improved rohu (Jayanti), and improved catla. The study finds that catla is more sensitive to PIT tagging and suggests an ideal size of 20-30g for tagging.

Summary: Temperate marine systems globally are warming at accelerating rates, facilitating the poleward movement of warm-water species, which are tropicalizing higher-latitude reefs. While temperature plays a key role in structuring species distributions, less is known about how species' early life stages are responding to warming-induced changes in preferred nursery habitat availability. We aim to identify key ecological and environmental drivers of juvenile reef fishes' distributions in the context of ocean warming.

Summary: Passive integrated transponder (PIT) and visible implant elastomer (VIE) tags are commonly used for identification in reptiles, amphibians, and fish. This study evaluated the pathologic changes associated with these tags in marine toads, showing that PIT tags had better retention and minimal histologic changes compared to VIE tags, which were found to migrate to the kidneys in 98% of the toads causing inflammation and damage over time. Based on these findings, the authors recommend the use of PIT tags over VIE tags for adult anurans when feasible.

Summary: The abundance of Capercaillie Tetrao urogallus was estimated in a Scottish forest using genetic and field methods. The genetic methods over-represented males and under-represented females compared to observations at leks and on brood counts. A genetic-based model for males estimated twice as many males as on lek or brood counts. Only 12% of males identified by genetic methods were detected 2 years later. The study concludes that the genetic sampling effort needs to be doubled for accurate population estimates.

Summary: This study analysed the recruitment variability of key species in an estuary between 2003 and 2019 and found that temperature-related variables have a significant impact on fish recruitment. A shift in the North Atlantic in 2010 coincided with a change in the common trends, particularly a decline in the trend of P. flesus and S. solea.

Summary: This paper proposes a SVNN-ANFIS approach based on single-valued neutrosophic numbers to evaluate the stability of open-pit mine slopes. The method utilizes neutrosophic numbers to express the truth, indeterminacy, and falsity information of influencing factors, and utilizes ANFIS to establish the relations between these factors and slope stability. The application results demonstrate high accuracy in both training and testing.
