Summary: The study compares the diversity and morphology of fungi dispersed by wind and three rodent species in recently harvested forests. It finds that wind-dispersed fungi are mainly wood saprotrophs, litter saprotrophs, and plant pathogens, while fungi dispersed in mammal scat are primarily mycorrhizal fungi, soil saprotrophs, and unspecified saprotrophs. The study also finds that mammal-dispersed spores are larger than wind-dispersed spores.

Summary: This study combines large amplicon sequencing data sets with bacterial phenotypic traits to investigate the impact of microbial dispersal patterns on the host specificity of the gut microbiome. The results suggest that both transmission mode and oxygen tolerance play a role in determining the specialization of microbes.

Summary: Biota in disturbance-prone landscapes have developed various strategies to persist long term, either locally or by regional recolonization. Habitat fragmentation and isolation can limit recolonization pathways and impact community reestablishment. This study investigates the effects of isolation on invertebrate community recolonization in a pristine intermittent stream.

Summary: This study explored the importance of dispersal and niche processes in the assembly of small mammal communities in a mountainous region of southwestern China. The results showed that dispersal played a dominant role in shaping the taxonomic composition of these communities. Additionally, communities from higher altitudinal areas were more influenced by dispersal processes.

Summary: This study assessed the levels of anthropogenic microplastics in benthic infauna from 20 subtidal stations in Galway Bay, Ireland. The results indicated that fibers were the dominant particle type, colors recorded in the organisms were mainly blue, and the ingestion of microplastics was associated with depth.

Summary: Increasing anthropogenic litter in the marine environment has provided substrates for fouling organisms. This study found 17 encrusting species on different types of stranded litter on beaches along the southeast coast of India, with one invasive species detected. The most common species associated with marine litter were bryozoans and barnacles. This is the first documentation of marine litter as a vector for species dispersal in India, highlighting the increasing risk of non-indigenous organisms invasion.

Summary: Seed dispersal plays a crucial role in species distribution and assembly. This study examined the link between seed dispersal patterns and coexisting species in a plant community. The findings suggest that seasonal differentiation in seed dispersal may have a greater impact on species assembly than dispersal vectors.

Summary: The study found that freshwater biodiversity in the Arctic decreases with increasing latitude, particularly more pronounced in mainland regions. There are significant dissimilarities between different regions, mainly due to connectivity limitations. Community composition is primarily influenced by temperature, while geology and precipitation are also important factors.

Summary: This study compared sperm quality/quantity in amphipods collected from six UK locations with varying water quality, finding that some sites had lower sperm counts compared to a nationally protected conservation area. Additionally, unknown reproductive stressors may impact E. marinas, an important food source for wading birds in Langstone Harbour, potentially related to agricultural runoff, landfill leachate, and storm water effluent.

Summary: New biodiversity records of echinoderms as epibionts on red king crabs in the Barents Sea provide insights into the symbiotic associations of this commercially important species. The presence of common starfish, Atlantic sea cucumber, green sea urchin, and brittle star on the invasive red king crab suggests potential ecological implications and predator-prey interactions that could benefit both species without negative effects on local populations.

Summary: This study provides the first insight into the role of epibiosis and the 'habitat cascades' phenomenon in enhancing structural heterogeneity and biodiversity in remote and difficult-to-access biogenic habitats, such as cold-water coral reefs and marine caves. It acts as a stepping-stone for further exploration of 'habitat cascades' in habitats where scientific knowledge about this phenomenon is limited.

Summary: Ocean sprawl and climate change have negative impacts on coastal erosion, habitat loss, and decreasing biodiversity. To combat these threats, nature-based solutions and coastal defence tools have been developed, but monitoring the effects on marine benthic organisms requires appropriate sampling designs and investigation methods.

Summary: This review examines the relationship between PAH effects on marine biota, environmental health status, and potential human health risks from consuming contaminated seafood. It found that mussels are the most evaluated bioindicator species, and benzo(a)pyrene and phenanthrene are the most investigated PAHs. However, there is a lack of multidisciplinary assessments that consider the link between environmental PAH dynamics, effects on aquatic biota, and human health risks.

Summary: This study evaluated the burden of As, Hg, Pb, and Cd in 314 marine fishes from the Amazon Coast. The results showed higher Hg concentrations in reef-associated fish compared to demersal fish. The study also found correlations between As, Pb, and Cd, suggesting similar dispersion properties and bioaccumulation homology. The concentrations of As exceeded guidelines and legal limits in a majority of the examined species, while Cd, Hg, and Pb levels were generally low. The estimated daily intake of iAs, Hg, and Pb were found to pose potential non-carcinogenic health risks.

Summary: Anthropogenic activities are negatively impacting marine ecosystems, leading to habitat degradation, loss of biodiversity, and chemical pollution. Climate change exacerbates the toxic effects of pollutants and ecological risks. Contamination by metals and metalloids is particularly important, yet neglected due to the increasing focus on plastic pollution.

Summary: This study aims to analyze data on elasmobranch-associated microbiota to understand its importance for the health of wild populations and captive individuals, as well as to guide future research. Sharp population declines have been observed globally for elasmobranchs due to excessive fishing pressure. However, emerging marine pollution associated with climate change has the potential to increase the spread of infectious agents, posing further threats to these species.

Summary: Vessel collisions pose a significant threat to various species of cetaceans, including both large and small ones. In addition to harming the animals themselves, collisions can also cause damage or sinking of vessels, thereby endangering human safety and marine industry economics. Bryde's whales appear to be particularly vulnerable to vessel strikes, and cases of such collisions have been reported worldwide. Long-term photo-identification research conducted in Sao Paulo, Brazil since 2016 revealed that 4% of the 67 Bryde's whales identified between 2004 and January 2022 exhibited scars consistent with propeller injuries from vessel collisions. These findings contribute to understanding the long-term impacts of collision injuries on the behavior and survival of Bryde's whales. The report aims to support future assessments of the conservation status of B. brydei in Brazil.

Summary: Several diseases, including spirorchiidiasis, have been reported to affect endangered wild sea turtle population worldwide. This study describes severe injuries in 16 juvenile green turtles from southeastern Brazil that were infected with spirorchiids. These injuries were categorized as extremely severe, affecting vital organs, and highlight the potential of spirorchiidiasis as a cause of death in stranded green sea turtles.

Summary: There is a scarcity of records regarding predation and scavenging events by sharks on marine megafauna along the Brazilian coast. This study presents unprecedented ecological interactions between sharks and various vertebrate groups through the analysis of carcasses found on the beaches of Bahia, Brazil. These records contribute to a better understanding of the species' ecology and life history.
