Summary: This study finds a distinct change in climate state in the Pre-Industrial climate model simulation of the CMIP6 model HadGEM3-GC31-LL around year 500. The onset of deep convection in the Weddell and Ross Sea gyres is identified as the cause of this step change, which is delayed due to a positive radiative balance and continuous ocean heat uptake during the model spin-up and initial pre-industrial control simulation.

Summary: The mountain ecosystems in the Hindu-Kush Himalayan (HKH) region are vulnerable to climate change and anthropogenic activities. The Yellow-Throated Marten (YTM) is a facultative predator that may lose much of its range by 2050 due to habitat loss and climate change, especially in the eastern part of the HKH landscape. Enhancing protection and improving habitat quality are necessary for the long-term viability of the species.

Summary: Understanding how animals adjust their physiological processes to track optimal conditions in response to climate change is crucial for predicting ecological responses. A study on endangered African wild dogs found that their birthing time has been delayed by 7 days per decade in response to long-term warming, leading to temperature changes in their reproductive process.

Summary: The thermal response of predators and prey to climate change has a significant impact on species interactions. Warmer and less seasonal climates are favorable for both species. Increasing seasonality has a proportionally larger impact on species pairs with different thermal performances than predation when climates become warmer and more seasonal.

Summary: The study revealed significant effects of the breeding range expansion of Laysan albatrosses on their foraging ecology, leading to the formation of distinct at-sea segregation and differences in foraging behavior in different oceanographic habitats. Birds from the new Eastern Pacific colony showed reduced foraging trip lengths and durations compared to those from the Central Pacific, resulting in significantly higher reproductive output and population growth rates.

Summary: Climate change affects predator-prey interactions by exacerbating thermal mismatches between predators and prey. In this study, we used micro-arthropod predators (S. scimitus) and prey (F. candida) to examine their interactions at different temperatures. We found that the lower thermal preference of F. candida altered top-down control by predators, with the strongest interaction strength at intermediate temperatures. Prey populations were highest at intermediate temperatures but declined at warmer temperatures. The results suggest that mismatches in thermal performance between predators and prey will impact predator-prey interactions in a warmer world.

Summary: Extreme weather events have limited understanding of their impacts on biological populations. This study analyzes the demographic impacts of an exceptionally violent storm on two populations of black-browed albatrosses. Contrary to expectations, the storm only affected the survival of albatrosses from one colony, leading to a doubled annual mortality rate. The findings suggest that extreme events can have different local-scale impacts on sympatric populations, hampering our understanding of the demographic responses to long-term climate shifts.

Summary: Wildfire extent shows seasonal and interannual variations due to climate and landscape-level factors, making prediction challenging. Linear models fail to capture the non-stationary and non-linear associations, reducing prediction accuracy. To address this, we utilize time-series climate and wildfire data from China, using unit root methods to improve wildfire prediction. Results highlight the sensitivity of wildland area burned to vapor pressure deficit (VPD) and maximum temperature changes in short and long-term scenarios. Furthermore, repeated fires limit system variability, leading to non-stationarity responses. We conclude that autoregressive distributed lag (ARDL) models better capture the interactions between climate and wildfire compared to linear models, providing insights into complex ecological relationships and guiding regional planners in addressing climate-driven increases in wildfire incidence and impacts.

Summary: The growth of tall woody vegetation in the Arctic, driven by warming, can accelerate climate change through positive feedbacks. Despite local evidence suggesting that large herbivores limit this vegetation shift, it remains uncertain whether herbivory pressure is a significant control on ecosystem structure and functioning at larger, regional scales. Our study on the Yamal Peninsula in West Siberia, using satellite remote sensing and data on reindeer migrations, reveals that higher reindeer herbivory pressure is consistently associated with lower coverage of tall woody vegetation. This suggests that, at current population densities, large herbivores counteract Arctic vegetation responses to climate change over large spatial scales.

Summary: Traditional methods of projecting future global human population growth based on birth/death trends overlook limitations and the impact of global carrying capacity. Recent data suggests that the global biocapacity may have already decreased to half of its historical value and the carrying capacity may be at its 1965 level and decreasing. Population projections also rely heavily on the fragility or robustness of essential ecosystem services.

Summary: In this paper, the pattern dynamics of the predator-prey model with interval biological coefficients and no-flux boundary conditions was studied. Boundedness of the solutions was shown by comparison principle and constructing an invariant rectangle domain with different interval variable values. The stable and unstable intervals of the positive equilibrium were discussed by treating the diffusion coefficient of the predator as the critical parameter. Amplitude equations around the threshold of the Turing instability were deduced using weakly nonlinear analysis method to classify the existence and stability of various pattern solutions. Non-symmetrical and symmetrical spatial patterns were displayed in 2D space through numerical simulation results with different interval biological coefficients.

Summary: The study demonstrates that population performance is influenced by both predator-prey relationships and climate change, with potential negative impacts on the population as predation increases and climate warming effects weaken. The interacting effects of climate and biotic interactions on population dynamics underline the complexity of ecological responses to environmental changes.

Summary: Invasive alien species pose a significant threat to freshwater ecosystems, but they are not explicitly mentioned in the Water Framework Directive (WFD) of the European Union. This article proposes a three-tiered approach for incorporating data on alien species into WFD assessments of freshwater bodies in Norway. It suggests inferring ecological status from available data, using evidence of the effects of alien species on biological quality elements, or classifying ecological status based on the ecological effect score of the alien species. The article also provides criteria for this assessment method and a list of alien species in Norway.

Summary: Alien species pose a major threat to global biodiversity, and stopping their spread before establishment is crucial. Understanding the pathways of introduction and their importance is essential for early detection and prevention. In Norway, terrestrial organisms are predominantly introduced through escape, parasites as contaminants, freshwater organisms by release, and marine organisms as stowaways. High-impact alien species are commonly introduced through the same pathways as other alien species. The number of pathways and overall introduction pressure are important predictors of ecological impact.
