Graphical abstract: Conducted continuous acoustic monitoring of cicadas at six sites in Tokyo–Kanagawa over 61 days in summer 2024, detecting six species. Seasonal calling patterns were broadly consistent, but some species extended their calls into nighttime hours at urban sites. Findings highlight interspecific variation in urban adaptation and demonstrate the effectiveness of audio recorders for long-term insect monitoring.

Graphical abstract: This study presents the first systematic inventory of street trees in Macapá, Northeastern Brazilian Amazon. Results reveal a dominance of exotic and fruit-bearing species, low tree density, and a replacement of large canopy trees by smaller ones, indicating potential losses in ecosystem services and the need for more biodiversity-focused afforestation planning.

Graphical abstract: Long-term (1976–2015) field sign monitoring of brown bears in northern Hokkaido, Japan, yielded 2421 records (feeding signs, tracks, scats) along 9890 km of survey routes. The digitized spatiotemporal dataset provides insights into population dynamics, habitat use, and feeding behavior across a major wildlife management policy shift.

Graphical abstract: Our study demonstrated that the “safe site” function of coarse woody debris (CWD) is not inherent to the downed log itself, which is nutrient-poor and physically harsh. Instead, facilitation is driven by the associated bryophyte carpet and accumulated humus, which elevate nutrient availability to levels comparable to forest soil. The results highlight a clear mechanism that CWD provides the physical platform or microhabitat for bryophytes, and the bryophyte community provides the chemical and structural environment necessary for successful seedling establishment.

Graphical abstract: This study developed a novel system of functional groups for testate amoebae based on 18 functional traits and assessed its ecological significance. We used hierarchical clustering on a trait database encompassing 372 species from the Northern Holarctic realm. Our analysis identified seven distinct functional groups, offering a more ecologically informative framework than traditional morphological classification.

Graphical abstract: We investigated the factors influencing water deer occupancy and their activity patterns during the summer season. The results suggested that occupancy probability decreased with increasing NDVI (normalized difference vegetation index), indicating a preference for grasslands and shrublands. Additionally, water deer exhibited distinct crepuscular activity patterns.

Graphical abstract: We developed high-precision genome assemblies for two endangered avian species in Japan, the Okinawa rail and the Japanese golden eagle, using a hybrid approach combining short- and long-read whole genome sequencing technologies. This method improved assembly contiguity, reduced missing data, and enhanced completeness, improving the results of conservation genetic analyses. Our approach provides a cost-effective strategy for generating high-quality assemblies of non-model animals for population and conservation genetics.

Graphical abstract: Metal hyperaccumulation may enhance plant fitness through multiple, non-exclusive mechanisms, including elemental defense against herbivores and pathogens, altered pollinator interactions, and increased reproductive performance in metal-rich soils. Metals may also affect plant–plant interactions via elemental allelopathy and improve stress tolerance, such as drought resistance. In some systems, hyperaccumulation may confer incremental defensive benefits, arise as a by-product of efficient nutrient acquisition in nutrient-poor environments, or serve as a means of metal sequestration and disposal.

Graphical abstract: We applied the Elements of Metacommunity Structure (EMS) framework to macrophyte communities across coastal wetlands in southern Brazil, identifying distinct distribution patterns among functional groups. Our results show that environmental and climatic factors shape these patterns differently, with emergent species forming Clementsian communities and submerged species following Gleasonian patterns. This study enhances understanding of species distribution and community structuring in aquatic ecosystems.

Graphical abstract: We investigated how habitat amount (forest cover) and configuration (edge density, number of patches) interact to shape insectivorous bat diversity in 28 islands of a Malaysian hydroelectric reservoir. Forest cover directly increased sonotype richness, but its indirect effects through edge density were negative, especially in highly deforested landscapes. Our results show that habitat amount and configuration are interdependent, and minimizing habitat loss is crucial to mitigate the associated effects of fragmentation on tropical bats.

Graphical abstract: We investigated manganese (Mn) accumulation in 25 Ilex species using X-ray fluorescence analysis of 2655 herbarium specimens. Nine species were identified as Mn hyperaccumulators, with several consistently showing high Zn concentrations and a strong Mn–Zn correlation. These findings reveal Ilex as a distinct lineage of Mn hyperaccumulators in non-contaminated soils.

Graphical abstract: Satellite tracking of Black Wood Pigeons in the Izu Islands (2022–2025) revealed frequent interisland movements, with flights ranging from 4 to 170 km. Many individuals dispersed among islands after breeding and returned the following spring, indicating partial migratory or nomadic behavior at the archipelagic scale. Habitat selection shifted with movement, with a preference for afforestation areas and Sasa shrubs during breeding, suggesting flexible use of island habitats driven by individual movement decisions.

Graphical abstract: Subterranean ecosystems in the Bodoquena karst region were studied to understand how microhabitat features influence invertebrate diversity across different spatial scales. The study found that species richness is positively related to trophic diversity and negatively to distance from cave entrances, with temperature and shelter availability also affecting community composition. The presence of 20 troglomorphic species underscores the region's conservation value, emphasizing the need for ongoing monitoring amid increasing human pressures.
