Sleep elasticity: accessory, useful and vital components of a single state
Published: 2026-08-19
Subjects: Biology, Ecology and Evolutionary Biology, Evolution, Neuroscience and Neurobiology, Systems Biology
Sleep is universal, homeostatically defended and apparently costly, and for half a century this combination has been read as evidence of a vital, conserved function still awaiting identification. The search has not converged. Instead, it has accumulated a dozen candidate functions, each defensible but none commanding assent. I argue that the difficulty lies with the question rather than with the [...]
Is Biology Necessary to Advance Biology?
Published: 2026-07-14
Subjects: Biochemistry, Biophysics, and Structural Biology, Biodiversity, Bioinformatics, Biology, Cell and Developmental Biology, Computational Biology, Philosophy, Scholarship of Teaching and Learning, Systems Biology
AI is transforming the workflow of biological science. But what role remains for human cognition when the priority is deep theory? We propose a division of labor based on a “coverage asymmetry” between artificial and biological agents. AI excels at extending the encounterable: scaling known mechanisms and exploring complex parameter regimes. However, AI cannot (yet) perform kind formation – the [...]
Computable Nature Dependency in a Watershed Knowledge Graph
Published: 2026-06-03
Subjects: Biodiversity, Ecology and Evolutionary Biology, Systems Biology
Resolving nature-related financial risk and watershed resilience requires a representational shift from opaque, aggregate indices to auditable, mechanistic pathways. Current natural-capital workflows often succumb to an "epistemic collapse", where granular ecological interactions are erased in favor of sector-level proxies or spatial heatmaps that lack a downstream asset trace. Here, we present a [...]
Rethinking angiosperm diversification through the functional integration of mutualisms
Published: 2026-05-02
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Plant Sciences, Systems Biology
Flowering plants have maintained exceptional diversity for over 100 million years despite repeated environmental change and mass extinction events. A central challenge in plant macroevolution is understanding how lineages achieve both extensive diversification and long-term persistence. While pollination, seed dispersal, and mycorrhizal symbioses are recognized as key drivers of plant evolution, [...]
Representational limits in detecting ecological change
Published: 2026-04-28
Subjects: Agriculture, Animal Sciences, Biochemistry, Biophysics, and Structural Biology, Biodiversity, Bioinformatics, Biology, Biotechnology, Cell and Developmental Biology, Ecology and Evolutionary Biology, Entomology, Food Science, Forest Sciences, Genetics and Genomics, Immunology and Infectious Disease, Laboratory and Basic Science Research Life Sciences, Life Sciences, Marine Biology, Microbiology, Neuroscience and Neurobiology, Other Life Sciences, Pharmacology, Toxicology and Environmental Health, Physiology, Plant Sciences, Research Methods in Life Sciences, Systems Biology
Detecting ecological change remains a persistent challenge, even in systems with extensive monitoring data and increasingly sophisticated analytical tools. Uncertainty is usually attributed to stochasticity, limited observations, or imperfect models. Here, I argue that an additional and largely overlooked constraint arises from representational limits: systematic ways in which graphs, indicators, [...]
Multi-scale collapse of coral cover under climate change

Projecting ecosystem trajectories under future climates is critical for conservation planning, yet remains constrained by uncertainty arising from limited data, ecological complexity, and biological and environmental variability. Variability, when disentangled from uncertainty, offers critical insights into population and community dynamics. For example, enhanced vital rates (growth, survival, [...]
Permissible Spite: Kin Selection, Demography, and the Inverse Hamiltonian Equation
Published: 2026-03-19
Subjects: Biology, Life Sciences, Social and Behavioral Sciences, Systems Biology
This article revisits Hamilton’s rule by proposing an inverted formulation to evaluate the evolutionary permissibility of spiteful behavior within kin-based populations. We formalize a reverse Hamiltonian equation and apply replicator dynamics to investigate the demographic and genetic conditions under which within group aggression may become evolutionarily stable. The model shows that in [...]
High-Resolution Coastal Blue Carbon Site Intelligence: A Multi-Attribute Geospatial Pipeline for National-Scale Mangrove Assessment
Published: 2026-02-25
Subjects: Biodiversity, Bioinformatics, Life Sciences, Systems Biology
The voluntary blue carbon market is severely bottlenecked by outdated methodologies that apply broad, coast-level carbon averages across low-resolution spatial units, systematically failing to account for micro-site ecological realities and critical socio-political constraints. To resolve this structural deficit, this paper introduces the High-Resolution Geographically-Explicit Blue Carbon [...]
Moving Target(s): One Health at changing human-livestock-wildlife interfaces in tropical ecosystems
Published: 2025-12-18
Subjects: Animal Sciences, Biodiversity, Biology, Ecology and Evolutionary Biology, Food Science, Life Sciences, Systems Biology
One Health approaches currently conceptualized for Western landscapes require fundamental rethinking for tropics, where human-livestock-wildlife interfaces exist as variegated mosaics rather than discrete zones. This overview examines why tropical ecosystems involve (i) Human mobility patterns shifting continuously through rural-urban migration and globalization (ii) Livestock health [...]
CartograPlant: Bridging genomic, phenotypic, and environmental data to advance plant resilience and eco-evolutionary insight
Published: 2025-09-30
Subjects: Agriculture, Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Genetics and Genomics, Integrative Biology, Life Sciences, Plant Biology, Plant Breeding and Genetics Life Sciences, Plant Pathology, Systems Biology
Climate change is threatening plant health and productivity at all spatial scales, and these impacts are further compounded by the rising incidence of invasive pests and pathogens. Effectively addressing these challenges requires a comprehensive understanding of plant demography as well as the mechanisms and drivers of adaptation. Achieving this understanding requires the integration of [...]
Opportunities for Cities to Cultivate Biodiversity
Published: 2025-08-11
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Policy, Environmental Studies, Other Ecology and Evolutionary Biology, Other Plant Sciences, Public Policy, Recreation, Parks and Tourism Administration, Systems Biology, Urban Studies and Planning
Cities pose a major threat to global biodiversity in every sense of the word. Municipal leaders have opportunities to promote biodiversity efforts in their cities. Several studies have shown that managing resources with biodiversity in mind within cities is effective and benefits both human and non-human residents and visitors. Two major opportunities for biodiversity investment in urban areas [...]
A systems-modelling approach to predict biological responses to extreme heat

Subjects: Animal Sciences, Comparative and Evolutionary Physiology, Evolution, Integrative Biology, Other Ecology and Evolutionary Biology, Systems and Integrative Physiology Life Sciences, Systems Biology
Anthropogenic climate change is leading to more frequent and extreme heat waves. These large-scale events are radically re-shaping interactions among organisms – impacting biodiversity, community composition and ecosystem services crucial to natural systems and food security. Predicting heat wave impacts on interacting species requires an understanding of the processes driving differential [...]
Toxin resistance mechanisms span biological scales in the Royal Ground Snake (Colubridae: Erythrolamprus reginae)

All predators of poisonous prey deal with toxins, yet we often lack an understanding of how the predators integrate various physiological adaptations to toxins. Here we investigate multiple complementary toxin resistance mechanisms in the pan-Amazonian snake Erythrolamprus reginae (Squamata: Colubridae), which consumes multiple species of poisonous frogs. We find that the toxin resistance [...]
Minimal viable sound systems for language evolution
Published: 2025-03-10
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Neuroscience and Neurobiology, Physiology, Systems Biology
Human vocal gamut covers 3000 unique speech sounds comprising the world’s languages, with each new speaker having to learn the sounds of its new language. Since large, expandable repertoires are facilitated by vocal learning, this capacity has long been considered a prerequisite for speech and language evolution. The postulation of a vocal learning and repertoire size ceiling has, however, never [...]
Abiogenesis as the origin of adaptive evolution. An alternative to the Oparin-Haldane model

Subjects: Biochemistry, Biochemistry, Biophysics, and Structural Biology, Cellular and Molecular Physiology, Comparative and Evolutionary Physiology, Computational Biology, Evolution, Molecular Biology, Molecular Genetics, Other Ecology and Evolutionary Biology, Population Biology, Systems and Integrative Physiology Life Sciences, Systems Biology
The emergence of life from non-living matter remains one of the most profound unresolved questions in natural philosophy. Current paradigms largely inherit the Oparin-Haldane assumption that abiogenesis is preceded by a prolonged accumulation of traits through both nonadaptive (e.g. self-organisation) and adaptive (i.e. natural selection) processes. Yet this raises a legitimate question: how can [...]
