Machine learning reveals the effect of leaf temperature extremes on shifts in plant photosystem heat tolerance thresholds
Published: 2025-12-15
Subjects: Life Sciences
Plant physiological heat tolerance thresholds can acclimate rapidly in response to changing leaf temperature, which varies considerably across microclimatic space and time. How leaf temperatures trigger shifts in these heat thresholds has not been established. We aimed to determine the influence of temporally proximal leaf temperatures (Tleaf) on leaf photosystem heat tolerance thresholds (Tcrit) [...]
Predicting unobserved driver of regime shifts in social-ecological systems with universal dynamic equations
Published: 2025-12-15
Subjects: Engineering, Physical Sciences and Mathematics, Social and Behavioral Sciences
Ecosystems around the world are anticipated to undergo regime shifts as temperatures rise and other climatic and anthropogenic perturbations erode the resilience of present-day states. Forecasting these nonlinear ecosystem dynamics can help stakeholders to prepare for the associated rapid changes. One major challenge is that regime shifts can be difficult to predict when they are driven by [...]
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 [...]
A protocol for biodiversity-informed wildlife disease surveillance
Published: 2025-12-13
Subjects: Biodiversity, Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences
Land use and climate change are increasing the risk of spillover of zoonotic disease into human populations. However, we lack actionable information about the prevalence of pathogens in wildlife populations for most of the globe, challenging our ability to implement strategies to prevent zoonoses. Even when this data exists, it has historically been sampled opportunistically and without guidance [...]
A One Health Sustainability framework for nature-based wellbeing
Published: 2025-12-13
Subjects: Ecology and Evolutionary Biology, Life Sciences, Medicine and Health Sciences, Mental and Social Health, Public Health
Human health benefits of nature are increasingly documented, yet the ecological conditions underpinning these benefits and the sustainability of nature-based interventions remain poorly measured. We introduce an integrated One Health Sustainability framework that links human health outcomes with ecological integrity, landscape pressures, and sustainability dimensions. This framework provides a [...]
Spatial Correlation Between Soil Phosphorus Distribution and Its Uptake in Bean Roots Using Lagrange, Hermite and IDW Interpolation Methods
Published: 2025-12-13
Subjects: Life Sciences
Phosphorus (P) is a key macronutrient required for plant growth, energy transfer, and root development, yet its mobility and bioavailability in soil are often limited due to fixation in insoluble forms. Understanding the spatial variability of soil phosphorus is therefore essential for optimizing fertilization strategies, particularly in legume crops such as common bean (Phaseolus vulgaris), [...]
R for marine ecologists: wrangling Earth System Model outputs
Published: 2025-12-13
Subjects: Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Marine Biology, Oceanography and Atmospheric Sciences and Meteorology
This one-day, hands-on workshop introduces marine ecologists to the use and application of Earth System Model (ESM) outputs using R–a free, open-source programming language widely used in marine ecology. Designed for participants with basic or no prior experience in climate modeling, our workshop: 'R for marine ecologists: wrangling Earth System Model outputs' provides a comprehensive foundation [...]
Functional or Dysfunctional? A Refreshed Perspective on Functional Feeding Groups
Published: 2025-12-11
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: 2025-12-11
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 [...]
Spores of arbuscular mycorrhizal fungi inhabiting inside mossballs of Rigodium implexum
Published: 2025-12-11
Subjects: Life Sciences
The spores of four species of arbuscular mycorrhizal fungi (Phylum: Glomeromycota): Acaulospora laevis, Acaulospora sieverdingii, Ambispora gerdemannii, and Dominikia aurea, were found inhabiting inside mosballs formed by Rigodium implexum at two forest sites in southern Chile. These species were identified through morphological keys. R. implexum mossballs are usually 10-20 cm in diameter, [...]
How pesticide exposure and effects match with the intention of European pesticide regulation – a mini review
Published: 2025-12-11
Subjects: Life Sciences
Pesticides are widely used in European agriculture, requiring robust prospective risk assessment of their environmental exposure and effects on non-target species to safeguard biodiversity. We conducted a high-level evaluation to test whether: 1) measured environmental exposure concentrations remain below those established by risk assessment and 2) these concentrations prevent population- or [...]
Behavioural repertoire and the onset of precocious sexual behaviours in juvenile ruffs (Calidris pugnax)
Published: 2025-12-10
Subjects: Animal Studies, Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences
Adult phenotypes are shaped by developmental processes during early life. This also applies to reproduction and dominance-related behaviours before maturation, called precocious sexual behaviours. However, beyond largely anecdotal reports, the onset of such behaviours is rarely studied. Here we document the development of precocious sexual behaviours in the ruff Calidris pugnax, a lekking [...]
The Origins of Human Cooperation Through Intergroup Relations in Our Closest Living Relatives
Published: 2025-12-10
Subjects: Life Sciences, Social and Behavioral Sciences
Cooperation is the foundation of human society, yet our understanding of its evolutionary origins and underlying mechanisms remains limited. This review draws on intergroup encounters in our closest evolutionary relatives, chimpanzees (Pan troglodytes) and bonobos (Pan paniscus), to better understand the evolutionary pressures and processes that shaped human cooperation. In chimpanzees, [...]
Mapping Cultural Ecosystem Service Flows from Social Media Imagery with Vision–Language Models: A Zero-Shot CLIP Framework
Published: 2025-12-10
Subjects: Computational Engineering, Computer Sciences, Natural Resources and Conservation, Nature and Society Relations, Sustainability
Geotagged social media imagery provides a valuable source for mapping cultural ecosystem service (CES) flows, which represent realized human interactions with nature, yet its open-world user-generated content poses challenges to automated content analysis. Supervised models require large labeled datasets and show limited generalization across contexts, whereas unsupervised approaches often need [...]
