Summary: Climate change increases extreme events in the sea, especially in coastal habitats. The impacts of heatwaves and upwelling events on a temperate keystone predator, the starfish Asterias rubens, were experimentally tested. It was found that prior exposure to present-day heatwaves alleviated upwelling-induced stress, indicating cross-stress tolerance. However, future projected heatwaves caused 100% mortality of starfish, indicating extensive mortality under intensified conditions.

Summary: A model was developed to predict the responses of overwintering avian herbivore species to changes in their environment, particularly in food availability and competition. The research showed that, despite challenges such as competition and reduced food resources, swans have the ability to increase their foraging effort to avoid starvation and successfully migrate. However, this increased foraging effort may lead to additional damage to agricultural crops. Interestingly, the decline in Bewick's swan numbers in recent years was found to be unlikely related to changes in winter food resources or competition.

Summary: Patients with stroke and unilateral spatial neglect (USN) show impaired working memory (WM), particularly in the binding between object identity and location. Errors in identification and localization were more prominent on the contralesional side, especially after a long retention interval. These errors were often due to swapping of correctly identified objects from the contralesional side to the correct locations of objects from the ipsilesional side.

Summary: Due to high productivity and past management approaches, the forests of Central Europe are dominated by conifers, even in areas where they are not naturally occurring. The vulnerability of Norway spruce to severe droughts and the lack of knowledge about how management strategies affect tree growth and drought responses emphasize the importance of this study. It found that the individual treatment history of a tree significantly influences its growth and drought resilience, with factors such as structural diversity, tree size, and thinning intensity playing a role.

Summary: Back-to-back marine heatwaves in 2016 and 2017 led to severe coral bleaching and mortality in the Great Barrier Reef. However, some surviving corals showed increased bleaching resistance, indicating the presence of thermally tolerant populations. By studying corals in different islands, researchers found that corals that had experienced recent bleaching events had higher survival rates during a subsequent heatwave compared to corals that hadn't experienced significant bleaching in a long time. Additionally, the surviving corals displayed different nutritional strategies and physiological performances, suggesting species-specific trade-offs in response to thermal stress.

Summary: Research has shown that raising temperatures above 20 degrees Celsius in Antarctic barren fellfield soils during summer can significantly reduce the abundance of decomposer fungi, such as Pseudogymnoascus roseus. High temperatures and high water availability also lead to decreased hyphal extension rates and enzyme activities in these cold-adapted microbes, indicating potential inhibitory effects of climate change on their metabolism.

Summary: The relationship between fungal community assemblies and substrate quality in different stages of wood decay significantly impacts the fungal species richness and weight loss of wood substrate. Early fungal communities exhibit neutral or negative relationships between species richness and wood decay, while late communities generally show significant negative relationships between the two. Differences in fungal communities and wood quality during wood decomposition play a key role in the fungal diversity-decomposition relationship.

Summary: This study investigates the relationships between oak wilt, climate, and wood-inhabiting fungal communities in apparently healthy Quercus serrata trunks in Japan. The results show that the composition and richness of fungal communities are significantly different between sites with and without oak wilt. Oak wilt is associated with increased richness of wood-inhabiting fungal communities, which is influenced by temperature and precipitation.

Summary: This study investigates the arthropod communities within fungal fruit bodies in boreal forests using DNA metabarcoding. The results show that arthropod diversity is higher in fruit bodies with a larger surface area-to-volume ratio, while long-lived fruit bodies have more physical or chemical defenses against arthropods. The composition of arthropod communities is influenced by various host traits. Soft and short-lived fruit bodies harbor more true flies, while tough and long-lived fruit bodies have more oribatid mites and beetles. Furthermore, close to 75% of the arthropods are specific to one or two fungal hosts.

Summary: During the decomposition of organic matter, the assembly history, resource quality, and the arrival of primary and secondary colonizers can affect the composition of fungal communities and the rate of wood decay. The study found that the gradient of fungal community composition is related to resource quality and that the initial fungal community explains the variation in community composition. Additionally, the exclusion of invertebrates has a lasting impact on fungal communities.

Summary: Dead wood is an important microsite for seedling regeneration in forest ecosystems. The type of fungal wood decay plays a significant role in determining the density and species composition of regenerating seedlings, but the underlying mechanisms are still unclear. This study conducted pot experiments with different tree species to evaluate their growth in different substrates. The results showed that different tree species respond differently to different substrates, and the colonization of mycorrhizal fungi is affected by the substrate as well.

Summary: We measured the extracellular bioelectrical activities of Laccaria bicolor, an ectomycorrhizal basidiomycete, under field conditions to explore its response to environmental factors. Initially, the fruit bodies showed lower electrical potentials, which may be attributed to the lack of precipitation. However, after raining, the electrical potential of the fruit bodies fluctuated, sometimes exceeding 100 mV. The electrical potential and its fluctuation were correlated with precipitation, and causality analysis revealed electrical signal transport among fruit bodies, especially between spatially close ones, with potential directionality.
