A Functionally Integrated Symbiotic System as a Mechanism for Angiosperm Diversification
Published: 2026-05-02
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Plant Sciences, Systems Biology
Flowering plants have maintained exceptionally high diversity for over 100 million years, yet the mechanisms enabling sustained macroevolutionary diversification remain unresolved. Classical theory predicts a trade-off between speciation and extinction, but angiosperms have repeatedly diversified while persisting across heterogeneous environments. Mutualistic interactions, pollination, seed [...]

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, [...]

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The voluntary blue carbon market is severely bottlenecked by outdated methodologies that apply broad, coast-level carbon averages across low-resolution spatial units, systematically failing to account for micro-site ecological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

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 [...]

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

Exposure to multiple toxic compounds imposes selective pressures across biological levels. There are several known toxin resistance mechanisms–such as behavioral avoidance, metabolic detoxification, and target-site insensitivity but an integrative approach to consider multiple toxins and resistance strategies. Predators of amphibians, for example, must counteract multiple chemicals secreted by [...]
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 [...]
On the feasibility of nonadaptive, nonsequential abiogenesis. An alternative to the Oparin-Haldane model
Published: 2025-02-18

The emergence of life from non-living matter remains one of the most profound unresolved questions in natural philosophy. The Oparin-Haldane model assumes a gradualist evolution, where adaptive precursors are obligated. Yet, for more than a century, all experimental efforts have failed to achieve abiogenesis. May it be that this view is paradoxical in explaining how living matter arises without [...]

Published: 2025-02-03
Subjects: Biodiversity, Biology, Ecology and Evolutionary Biology, Integrative Biology, Systems Biology
Global biodiversity and ecosystem function are the result of complex networks of interactions and feedbacks between animals and their environments, which in turn are affected by the interactions and feedbacks between mammals and the organisms they host. Bats are important contributors to ecosystems and biodiversity maintenance, so understanding their complex interaction networks, including the [...]
Different sources of wind turbine data produce sharp differences in collision risk estimates for foraging vultures
Published: 2024-12-06
Subjects: Biodiversity, Environmental Monitoring, Systems Biology, Zoology
Multiple studies assessed the collision risk of different vulture species with wind turbines. However, they relied on different sources of wind turbine data, and the effect of this data heterogeneity, on the estimated collision risk and the comparability of these assessments, has not been investigated. We used GPS and accelerometer data, collected from 6 adult Griffon Vultures living in Sardinia [...]
