Summary: Anadromous Arctic char and their freshwater habitats in the Canadian Arctic, particularly in the Nunavik region, are vulnerable to the impacts of climate change. Inuit knowledge holders have provided valuable insights on the optimal spawning habitats for Arctic char, indicating the importance of rivers with specific depth, velocity, and substrate characteristics. By using fuzzy logic and local observations, a quantitative model was developed to predict the suitability of spawning sites, demonstrating the potential applicability of this methodology for other species with local or traditional knowledge.

Summary: During spawning, adult Pacific salmonids face challenging upriver migrations where energy and oxygen delivery must be balanced with locomotion, maturation, and spawning behaviors within the constraints of cardiac capacity. This study implanted migrating adult Chinook salmon with heart rate biologgers to monitor cardiac function, finding that water temperature, discharge, fish size, and fish origin all influenced heart rate. Wild fish had slower resting heart rates and higher scope for heart rate variation compared to hatchery fish.

Summary: The importance of animals in mediating ecosystem processes has long been recognized by ecologists, as they play critical roles in both consumptive pathways like predation and herbivory, as well as in bottom-up pathways associated with nutrient dynamics. Research has shown the significant impact of consumer-mediated nutrient dynamics in terrestrial, freshwater, and marine ecosystems, inspiring further studies on their role in ecosystem function. This study provides comprehensive data on consumer nutrient dynamics in subtropical and tropical Caribbean coastal marine waters, offering valuable insights for advancing ecological theory and applied science in tropical marine ecosystems.

Summary: The study examines fish stoichiometry traits in coral reefs and finds that phylogeny plays a critical role in nutrient cycling, especially in the Caribbean region. In Polynesia, ecological factors have a greater influence on chemical trait variation. Regional differences in chemical traits can be explained by nutrient limitation associated with different geological contexts.

Summary: The purpose of this study was to examine the associations between infants' dietary nutrient trajectories and subsequent neurodevelopment during childhood. One-day food records were collected at ages 6, 9, and 12 months, and neurodevelopment assessments were conducted at ages 24 and 54 months. The findings showed that higher protein intake and increasing rate of intake were associated with higher fine motor scores at 24 months, while higher fat intake was associated with higher receptive language scores. However, no significant associations were observed with neurodevelopment at 54 months. Overall, this study provides important insights into the relationship between nutrition and child neurodevelopment over time.

Summary: This study reveals and describes the variability in the blood plasma proteomes of male and female pink salmon during their spawning migration. The blood proteomes of the two genders show qualitative and quantitative differences, with females having proteins associated with reproductive system development, lipid transport, and energy production, while males have proteins involved in blood coagulation, immune response, and reproductive processes. These findings contribute to both fundamental and practical knowledge about the biochemical adaptations of pink salmon during spawning.

Summary: Hippopotami play a crucial role in aquatic ecosystems by transferring organic matter and nutrients, affecting biogeochemical cycling. Pools with high hippo subsidies quickly become anoxic and export harmful substances, while pools with low subsidies can act as nutrient sources or sinks. Maintaining a natural flow regime, including flushing flows, can help mitigate the impacts of hippos on water quality.

Summary: Scavengers play a critical role in nutrient recycling and disease control, particularly after mass mortality events. Research on scavenger ecology during mass mortality events is limited, but it is found that different scavenger species show temporal resource partitioning and distinct activity patterns. Further studies on scavenger behavior during mass mortality events are needed to understand their role in decomposition and disease control.

Summary: Despite extensive stocking efforts for Yellowstone Cutthroat Trout, populations have declined relative to nonnative salmonids in the North Fork Shoshone River drainage. The increase of introduced nonnative salmonids likely further reduced stocking success of Yellowstone Cutthroat Trout due to competition and hybridization, showing the importance of long-term stocking records for successful management of imperiled fish populations.

Summary: Native freshwater fish are declining globally, and understanding their resilience to disturbance is crucial. This study in Wyoming, USA, found that mountain sucker recovered faster than mottled sculpin after displacement, likely due to their superior movement and colonisation abilities. Colonisation was influenced by pre-displacement abundance, riparian cover, and species identity.

Summary: Animals can have long-lasting legacy effects on freshwater ecosystem structure and function, with declines or disappearances of native populations leading to loss of these effects. Anthropogenically altered animal populations, such as livestock and invasive species, may provide new legacy effects but with important functional differences. Conservation and restoration of native species are crucial for maintaining the structure and function of river ecosystems in the face of biodiversity loss.

Summary: All animals carry specialized microbiomes that are continuously released into the environment through waste excretion. The concept of a meta-gut system is proposed, where the gut microbiome released from an animal could influence biogeochemical processes in recipient ecosystems and potentially impact other hosts. This dynamic may also occur in high-density animal gathering areas, particularly in aquatic environments.

Summary: Hybridisation with introduced species is a threat to native fish populations. Temporal isolation, as a mechanism of reproductive isolation, can limit or prevent hybridisation between closely related species. However, despite the spawning timing difference, substantial overlap in spawning seasons leads to ongoing hybridisation between Yellowstone cutthroat trout, rainbow trout, and hybrids.

Summary: Climate change and non-native species pose significant threats to biodiversity in Lake Baikal. Based on empirical data and theoretical analysis, this study reveals that the current limitation on the spread of non-native species is primarily attributed to dispersal. However, projected temperature increases are expected to overcome this limitation and allow non-native species to establish in Lake Baikal, leading to negative impacts on endemic species.

Summary: Redd counts are commonly used to estimate spawning population size for salmonids, but observation error can compromise their utility. In this study, we evaluated the effects of superimposition on the error structure and biological significance of redd count data for Yellowstone cutthroat trout spawning in tributaries to the Snake River, Wyoming. We found that although there was low detection of redd clusters, overestimates of the number of redds per cluster balanced this out, resulting in accurate counts reflecting census redd abundance.
