Summary: This study investigates the impact of temperature and radiation on carbon uptake in temperate and cold regions. The results show that radiation constrains the temperature response during the end-of-season, while temperature has a strong influence on the start of carbon uptake.

Summary: Poleward distributional shifts and phenological adjustments are common ecological responses to ocean warming. A new framework proposed in this study analyzes the alternative acclimatization pathways that can include or exclude timing and poleward shift. The analysis of horse mackerel and Atlantic mackerel in the northeast Atlantic showed contrasting responses to warming, with horse mackerel spawning earlier and Atlantic mackerel shifting northward. These new insights have implications for fisheries management and habitat projections under climate change.

Summary: Pacific salmon can suffer injuries and mortality during their migration to spawn. Understanding how these injuries change over time and how they affect spawning success is important for predicting losses accurately. However, further research is needed to refine injury assessment methods and understand injury dynamics at the individual level for population-level predictions.

Summary: This study utilized 19 years of remote sensing data to analyze the effects of climatic variability on terrestrial vegetation in six protected areas of southwestern South America. The results showed that different climate oscillations had varying impacts on phenological activity of vegetation at different latitudes. Further long-term studies are needed to improve our understanding of the influence of climate change on vegetation condition and phenological variability in the region.

Summary: Climate change is altering the growing seasons of plants, affecting species performance and biogeochemical cycles. The timing of autumn leaf senescence in Northern Hemisphere forests is uncertain, but early-season and late-season warming have opposite effects on leaf senescence, with a reversal occurring after the summer solstice. Increased temperature and vegetation activity before the solstice led to an earlier senescence onset, while warmer post-solstice temperatures extended senescence duration. These changes in leaf senescence can impact growing-season length and forest productivity in the Northern Hemisphere.

Summary: Accurate predictions about the timing of Atlantic salmon smolt migration between freshwater and marine environments are crucial for effective management. This study used data from 41 rivers in Norway to develop a predictive model, finding that air temperature and counting method significantly influenced the timing of smolt emigration. The model suggested that previous national estimates underestimated migration timing in southern populations.

Summary: Ocean warming is causing fish species to shift their ranges poleward, impacting the spawning phenology and reproductive output of black sea bass populations in different distributional ranges. Results show that northern populations of black sea bass have shorter spawning seasons and lower reproductive output compared to populations in their historic range.

Summary: Through satellite ocean color measurements and sockeye salmon stock-recruit data analysis, a significant positive correlation between Fraser River sockeye productivity and summer chlorophyll a concentrations in the northwestern Gulf of Alaska has been revealed. The strong correlation, particularly near Kodiak Island in the northern Gulf of Alaska during midsummer, suggests the potential impact of mesoscale oceanographic processes on sockeye salmon prey abundance and productivity. These findings highlight the importance of considering ocean dynamics in understanding sockeye salmon survival and identify a key region for future research.

Summary: Alpine plants prosper in treeless vegetation above the high elevation climatic treeline through their small stature, apt seasonal development, and 'managing' of the microclimate. Despite the wide range of thermal niches provided by the alpine environment, certain habitat types may shrink with climate warming, posing challenges for some plant species.

Summary: The timing of entry into freshwater by mature anadromous fishes is determined by migration cues, particularly photoperiod, and shows high individual repeatability. This study used passive acoustic telemetry to track 71 twaite shad returning to the River Severn's upper estuary over multiple spawning seasons, and found that the timing of river entry was consistent between years and strongly predicted by increasing day length. Water temperatures and flow rates, however, were weak predictors and highly variable between years. The results highlight the importance of understanding migration cues and their variability in assessing the migration phenology of anadromous species.

Summary: Rapid climate change is significantly impacting Arctic ecosystems and the livelihoods of Indigenous peoples. This project examines the effects of climate change on Pacific salmon in the Inuvialuit Settlement Region. Using interviews and voluntary harvest data, researchers found an increase in salmon harvest in recent years attributed to regional environmental change. Concerns were raised about the negative impacts of salmon on cultural traditions and preferred fish species. This study emphasizes the importance of researching Arctic salmon and their potential influence on freshwater ecosystems.

Summary: The study of Pacific herring spawning patterns in Prince William Sound revealed that changes in spawning time and location were associated with the failure of population recovery. Spatial and temporal shifts in spawning areas and timing may have implications for survival and recruitment, but further research is needed to understand the effects.

Summary: Climate change can indirectly affect the phenological performance, including bud burst, of seedlings by influencing the temperature during seed maturation. This effect may be related to maternal factors and transgenerational epigenetic memory. Furthermore, the sensitivity of bud burst and leaf senescence to temperature varies.

Summary: Understanding the distribution of snow-water equivalent (SWE) is crucial for predicting water resources in the western United States. This study found that most variance in peak SWE can be explained by the timing of snow disappearance, onset, and cover duration, with variations primarily related to climate conditions. The use of remotely sensed snow timing information was shown to be effective in quantifying spatial patterns of peak SWE over the past two decades.
