Summary: This study used unsupervised machine learning to analyze the relationship between mercury bioaccumulation in fish and biogeochemical conditions and landscape, revealing that different fish species respond differently to various forms of mercury. Additionally, dissolved MeHg was found to have a significant impact on mercury bioaccumulation in fish.

Summary: This study evaluates eight global ocean reanalysis products against available in situ and satellite ocean observations in the Northeast U.S. continental Shelf (NES). Results show that coarse resolution products have limited skill in the coastal environment, while high-resolution products better represent temperature and salinity. Common biases exist in all reanalyses, with larger biases in the southern Mid-Atlantic Bight. GLORYS and BRAN stand out for their superior performance, outperforming other products in multiple metrics. The Gulf Stream and local bathymetry are critical factors leading to differences between the reanalyses.

Summary: This study examined the impact of climate change on stream ecosystems by developing species distribution models and projecting changes under different greenhouse gas emission scenarios. The results suggest that as climate change worsens, cold-water taxa will decrease while warm-water taxa will expand, leading to an increase in overall species richness but a drastic decrease in beta diversity.

Summary: This study analyzed data from winter and summer cruises as part of the Northeast U.S. Shelf Long-Term Ecological Research program and found that coastal waters had higher phytoplankton biomass dominated by large cells in winter and small cells in summer. Phytoplankton growth rates were correlated with temperature, light availability, and community size-structure, while grazing rates were not correlated with total chlorophyll a, indicating other biological drivers at play in predator-prey interactions at the first trophic level.

Summary: The study investigated the spatial distribution pattern of field insect communities and found that the structure and functional groups of the insect communities change dynamically with time, although maintaining a relatively high and stable level within the 400 x 400 m plot. The research collected a total of 6085 samples of corn farmland insects, providing valuable insights for pest control in the spring corn area of Northeast China.

Summary: The Northeast U.S. continental shelf has been rapidly warming in recent decades, leading to local variability in water properties. The mixed layer depth (MLD) plays a key role in determining upper ocean warming, with clear seasonal cycles observed across different regions on the NEUS continental shelf. While temperature-based MLDs generally agree with density-based MLDs, there are some biases in certain seasons, suggesting the need for further studies on the drivers of temporal and spatial MLD variability in this region.

Summary: The study found that most forage fish species on the Northeast US shelf have increasing or stable shelf occupancy in both spring and fall, likely linked to gear shifts and increasing bottom temperature and salinity. However, exceptions include decreases in shelf occupancy by sand lance and decreases in habitat suitability for Atlantic herring in the fall.

Summary: Predicting the impact of marine ecosystem warming on phytoplankton production is difficult. We studied the response of phytoplankton to increased temperature in the Northeast US Shelf Ecosystem using sea surface temperature and chlorophyll remote sensing data. The timing and magnitude of the spring thermal transition did not change significantly, but there was a significant change in the autumn transition. The timing and duration of the autumn bloom also changed, with a later initiation and shorter duration.

Summary: This study examined the dispersion and settlement of sea scallop larvae, showing that larval dispersal is influenced by biophysical interactions and larval behavior in the ocean mixed layer. Additionally, the larval transport is closely related to the intensity and duration of northeasterly winds, with the exception of significant larval transport to the Middle Atlantic Bight in 2009 driven by unusually strong northeasterly winds.

Summary: Insects, including bees, play a crucial role in pollinating food crops and wild plants. The diet and habitat needs of bee taxa are well known, but not as much for other pollinating insects. Understanding the diversity in diet and habitat of non-bee pollinators is important for their conservation and management.

Summary: The impacts of environmental constraints during development on the behavioural response of fishes are not well understood. This study examined how early exposure to the pyrethroid insecticide permethrin influenced phenotypic traits in mangrove rivulus fish. The results showed that larval exposure to high concentration permethrin led to slower growth, decreased activity, negative thigmotaxis, and reduced prey capture. Additionally, adult fish previously exposed to high concentration permethrin showed overcompensated growth and altered aggression behavior during contests. This study highlights the immediate and persistent effects of permethrin on phenotypic traits and suggests an interaction between pyrethroids and hormones in affecting animal behavior.

Summary: The transition from freshwater to saltwater is challenging for Atlantic salmon, and survival during this critical life stage is believed to affect adult population abundance. However, the role of feeding in influencing growth and survival is not well-studied. In this study, we analyzed the diet of post-smolts captured in Norwegian fjords and found that their diet mainly consisted of fish larvae, krill, planktonic amphipods, and insects. Diet varied among fjords and years, with post-smolts in northern Norway displaying a higher frequency of fish larvae in their diet. Post-smolts consuming fish larvae and/or krill had higher feeding ratios and were longer on average, indicating the importance of these prey items for marine growth and survival. These findings may have implications for Atlantic salmon marine survival rates in the region.

Summary: The degradation of Xing'an permafrost in Northeast China affects the stability of carbon pool and carbon emissions of the hemiboreal ecosystem. This study used the InVEST model to simulate the changes in aboveground biomass, belowground biomass, dead organic carbon, and soil organic carbon in the permafrost regions. The results showed a significant reduction in permafrost extent and a decrease in carbon stock, highlighting the importance of further research on carbon budgets.

Summary: Forage fishes play a critical role in marine ecosystems as a key link in the food web, forming hierarchical patch structures across different scales. Surface-level forage fish aggregations (FFAs) provide a concentrated prey source for surface- and shallow-foraging marine predators. However, existing survey methods do not adequately capture the scale of foraging predators, making it difficult to understand predator-prey interactions. This study used Bayesian joint species distribution models and aerial digital surveys to assess the distribution patterns and drivers of forage fish aggregations in the US Northeast Continental Shelf (NES) ecosystem. The results showed that bathymetric depth influenced both community species richness and surface FFA abundance, while subsurface and surface features influenced aggregation behavior and forage fish diversity.
