Community structure of macroinvertebrates in freshwater rock pools of the Brazilian semiarid region
Published: 2025-12-23
Subjects: Terrestrial and Aquatic Ecology
Freshwater rock pools (FRPs) are temporary aquatic environments that provide refuge for biodiversity in regions with low precipitation. The macroinvertebrate communities of FRPs in the Brazilian semi-arid region constitute an important link between aquatic and terrestrial ecosystems, given their dependency on both to complete their life cycles. The knowledge about FRPs and their resident biota [...]
Scale mismatches limit the efficacy of customary management
Published: 2025-12-18
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
1. Indigenous lands are some of the most biodiverse areas in the world, providing protection for many species and spillover benefits for wider communities. However, these areas face increasing threats. Indigenous communities face many challenges in protecting and managing these lands, particularly in the form of power imbalances and spatial, temporal, and functional-conceptual mismatches. 2. [...]
Deciphering the patterns and drivers of tardigrade diversity along altitudinal gradients
Published: 2025-12-15
Subjects: Animal Sciences, Biodiversity, Life Sciences, Terrestrial and Aquatic Ecology, Zoology
Altitudinal gradients offer a unique opportunity to understand the drivers of species richness, as mountain regions cover vast areas and contribute disproportionately to global terrestrial biodiversity. However, most studies have focused on larger organisms, often neglecting microscopic animals such as meiofauna also in mountain biodiversity research. In this study, we investigated patterns of [...]
The potential of fish families as surrogates for species and functional diversity in biomonitoring impacted Amazonian streams
Published: 2025-12-15
Subjects: Terrestrial and Aquatic Ecology
Compared to the accelerated progress of environmental degradation in Amazonian ecosystems, the development of studies to support conservation efforts is slow, because it demands substantial financial and logistical investment. Intending to contribute to stream monitoring with rapid analyses, this study aimed to test the feasibility of using species composition for taxonomic families as biological [...]
Functional or Dysfunctional? A Refreshed Perspective on Functional Feeding Groups
Published: 2025-12-12
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Functional feeding groups (FFGs), introduced in the 1970s, provided a framework for understanding freshwater ecosystems by classifying macroinvertebrates according to feeding mode and diet. Since then, the FFG approach has been widely applied and has significantly advanced our knowledge of ecosystem processes and functions. However, the framework represents a simplified view of complex trophic [...]
Biochar–Microbial Synergistic Systems for Nitrogen and Phosphorus Removal in Polluted Waters: Mechanisms, Studies, and Insights
Published: 2025-12-12
Subjects: Environmental Engineering, Microbiology, Terrestrial and Aquatic Ecology
Eutrophication caused by increasing non-point source pollution has resulted in the accumulation of nitrogen and phosphorus in water bodies, leading to severe algal blooms, oxygen depletion, and ecosystem degradation. However, conventional remediation technologies often face limitations in efficiency and sustainability. Biochar, derived from organic waste, has gained attention for its strong [...]
Quantifying Three Decades of Artisanal and Small-scale Gold Mining Frontiers in the Guiana Shield (1995–2024)
Published: 2025-12-10
Subjects: Artificial Intelligence and Robotics, Biodiversity, Earth Sciences, Ecology and Evolutionary Biology, Environmental Monitoring, Environmental Sciences, Geography, Life Sciences, Natural Resources and Conservation, Remote Sensing, Sustainability, Terrestrial and Aquatic Ecology
Artisanal and Small-scale Gold Mining (ASGM) is a leading driver of tropical deforestation and forest degradation, yet its spatial and temporal dynamics remain largely underexplored. Here, we present a pan-regional, annual time-series analysis of ASGM expansion across rainforests of the Guiana Shield (Guyana, Suriname, and French Guiana) from 1995 to 2024. Using Landsat imagery, we trained a deep [...]
New species discoveries redefine global biodiversity patterns
Published: 2025-12-03
Subjects: Terrestrial and Aquatic Ecology
Global biodiversity patterns are fundamental to ecology and conservation. However, these patterns are based on incomplete and rapidly growing taxonomic knowledge, and the influence of new species discoveries on our understanding of global biodiversity remains poorly understood. Here we quantified how the discovery of terrestrial vertebrates from 1920 to 2020 has reshaped estimated global [...]
An overview of passive acoustic monitoring (PAM) of terrestrial vertebrates and its significance, applications and challenges in urban and natural environments
Published: 2025-11-30
Subjects: Terrestrial and Aquatic Ecology
Amidst a global biodiversity crisis and unprecedented levels of species loss, effective environmental monitoring is more important than ever, but traditional methods are often labour intensive and subjective. Passive acoustic monitoring (PAM) is rapidly establishing itself as an important non-invasive, scalable and cost-effective tool for surveying sonant fauna in both natural and urban [...]
Forest fecundity declines as climate shifts
Published: 2025-11-28
Subjects: Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Tree fecundity underpins regeneration, range tracking, and seed supply for assisted migration, yet may decline as climates move beyond reproductive niches. Using 34 years of nationwide harvest records from Poland (40,530 observations across 438 forest districts) for five dominant taxa — oaks (Quercus robur, Q. petraea), European beech (Fagus sylvatica), Scots pine (Pinus sylvestris), and silver [...]
A theoretical framework for multispecies coexistence in large herbivores based on functional traits and dietary data
Published: 2025-10-31
Subjects: Biodiversity, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Modern Coexistence Theory (MCT) has long aimed to predict community structure, but empirical support remains scattered across unconnected case-studies from a narrow subset of systems where it is possible to quantify niche and fitness differences (e.g., pairwise interactions between fast-growing plants or protists). We sought a framework to apply MCT to a broader range of ecological scenarios by [...]

Host specificity and activity synchronization drive frog-biting midge incidence on torrent frogs (Hylodidae) in southeastern Brazil
Published: 2025-10-28
Subjects: Other Ecology and Evolutionary Biology, Population Biology, Terrestrial and Aquatic Ecology
Frog-bitting midges (Corethrellidae) are widespread micropredators that feed on the blood of frogs. Furthermore, frog-biting midges carry pathogens such as Batrachochytrium dendrobatidis (Bd), an important cause of worldwide amphibian declines. Female midges usually target calling male frogs by using acoustic cues. However, how midges target frogs that use conspicuous visual cues, especially [...]
