The amphibian chytrid fungus, Batrachochytrium dendrobatidis (Bd), has been implicated as an agent of acute declines in populations worldwide. East Asian amphibians have coexisting with Bd for long periods and thus are considered resistant; among the many is Japanese tree frog, Dryophytes japonicus. Our study focused infection effects on reproductive behaviors physiological parameters D. japonicus a function better understanding chronic effect disease long-term population viability. During...

The hibernation of amphibians can offer a unique window into overwintering adaptation processes and host-gut microbiota interactions through changes in metabolic availability homeostasis. We attempted to identify differences the physiology gut microbiome during after Japanese wrinkled frogs (Glandirana rugosa), an aquatic amphibian. After hibernation, high alpha beta diversity bacterial community appears reflect more diverse complex environmental conditions. During winter, Proteobacteria...

ABSTRACT Forensic entomology is a sub‐discipline of concerning insects and arthropods with their relationship to criminal investigations. Most important that comes out it the finding an exact time occurrence dead body by estimating post‐mortem interval (PMI). Our study focused on blow fly pupae, which are some earliest colonize decomposing bodies. The pupae have longest development period in life history, but we trouble viewing inside because puparium. It is, therefore, developmental...

ABSTRACT This study investigates the influence of microenvironmental factors on carcass decomposition and insect colonization, emphasizing detailed analysis communities. The research involved placing two pig carcasses in contrasting environments: one a sunlit open field other shaded forest area. Over 10 days, we observed variations rates, with area decomposing faster than shade. applies Symbolic Aggregate approXimation to transform daily measurements weight into symbolic sequences, enabling...

As the advantages of wind energy as an eco-friendly strategy for power generation continue to be revealed, number offshore farms also increases worldwide. However, turbines can induce behavioral and physiological responses in animals by emitting various types noises. In this study, we investigated behavioral, physiological, immunological male Japanese tree frogs (Dryophytes japonicus) when exposed turbine noise. To determine effects during breeding season, were collected from areas with...

Abstract River ecosystems face growing threats from human‐induced stressors, resulting in habitat degradation and biodiversity loss. Crucial to these ecosystems, macroinvertebrates maintain river health functioning. In this review, we examine the challenges confronting macroinvertebrates, explore restoration strategies management approaches, shed light on knowledge gaps future research directions. Habitat degradation, water pollution, climate change, invasive species are discussed as key...

Tadpoles present an intriguing model system for studying the regulation and selection of gut microbiota. They offer a unique perspective to enhance our understanding host-microbiota interactions, given their capacity alter dynamics microbial community by interacting with multiple environmental factors within complex life cycle. In this study, we comprehensively investigated variations in growth rate bacterial relation temperature differences during process amphibian metamorphosis. Higher...

The gut microbiota maintains a deeply symbiotic relationship with host physiology, intricately engaging both internal (endogenous) and external (exogenous) factors. Anurans, especially those in temperate regions, face the dual challenges of significant influences like hibernation complex variances tied to different life histories. In our research, we sought determine whether stages (juvenile versus adult) Japanese wrinkled frog ( Glandirana rugosa ) lead distinct shifts bacterial communities...

Abstract We reviewed the texts from 22,179 publications in journals published last 100 yr by Ecological Society of America. quantified relative use terms and identified temporal trends research collaborations using text‐mining methods. Terms concerning ecological topics at population level such as structure, function, competition relating to influences environmental factors were frequently used throughout this century. Relative higher hierarchical levels (i.e., ecosystem, landscape) has...

Anthropogenic connectivity regulation in rivers, such as via weirs and dams, affects the plankton community. We hypothesized that longitudinal similarity of zooplankton community a river could change river–reservoir hybrid system (RRHS). The impact weir construction on communities terms species diversity, abundance, structure was examined biweekly at six sites Nakdong River for 14 years (before construction: 2002–2008; after 2012–2018). checked time-series alignment using dynamic...

Many freshwater ecosystems are becoming more saline, and amphibians, which have permeable skin, sensitive to this change. We studied the physiological responses high salinity recovery from saline exposure in adult frogs (Pelophylax nigromaculatus). Frogs that experienced severe were exposed conditions for 6 days, while those moderate group 40 followed by a period 20 days. Our data showed during of groups, serum electrolytes increased, protein concentrations decreased, creatinine, an...

The calling behavior of anurans should be studied in detail as it greatly influences their physiology and immunity, particularly prolonged breeding species. effect can further complicated by the emergence timing season. We conducted a study comparing Japanese tree frog (Dryophytes japonicus), breeder species, according to timing. During middle season, high chorus size appeared, indicating peak. However, did not dominate behavior. In early frogs had energy storage state immunity. individuals...

We studied the effects of forest fragmentation and management practices on carabid beetle (Coleoptera: Carabidae) assemblages in Japanese red pine forests Naju City, South Korea.A total 2,058 individuals, representing 15 species, were collected by pitfall trapping from May to September 2010 three types: native (relatively undisturbed forest), managed (planted trees with clear-cutting herb layer), patch (fragmented forest).We showed that different types differed significantly terms their...

Abstract We analyzed the research topics and public concern on Vespa velutina as an invasive species in Asian European countries quantitatively though digitized texts such scientometrics conservation culturomics. collected 126 scientific publications of V. published during last three decades, 423 news articles South Korea. In total, 22 have contributed to . Research were clearly classified studies taxonomy invasion Korea, people recognized ecological health impact Although interest has...

Anuran species can respond to environmental changes via phenotypic plasticity, which also result in ecological impacts across the life history of such species. We investigated effects predation pressure (i.e., non-consumption effect) from dragonfly larva (Anax parthenope) on phenotypical change tadpoles into juvenile frogs (specifically black-spotted pond frog, Pelophylax nigromaculatus), and analyzed impact morphological locomotory performance after metamorphosis. The experiments predator...

Abstract The relationship between the gut bacterial communities of carabid beetles and their habitats holds implications for understanding ecological dynamics. This study examined two beetle species, Chlaenius pallipes Pheropsophus jessoensis , in terraced flat paddy fields. Differences were evident at species level based on habitat. Specifically, P. had a greater presence Firmicutes Proteobacteria fields but more Actinobacteria flatland In comparison, C. consistently showed high levels both...

Abstract Citizen science (CS) is the most effective tool for overcoming limitations of government and/or professional data collection. To compensate quantitative 'Winter Waterbird Census Korea', we conducted a total four bird monitoring via CS from 2021 to 2022. use alongside national data, studied quality and improvement utilizing (1) digit-based analysis using Benford’s law (2) comparative with data. In addition, performed community CS-specific demonstrating necessity CS. Neither nor...
