Not by selection alone: expanding the scope of gene-culture coevolution
Published: 2024-09-06
Subjects: Anthropology, Biological and Physical Anthropology, Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Genomics, Social and Behavioral Sciences
Gene-culture coevolution (GCC) - an ambitious synthesis of biological and social sciences - is often used to explain the evolution of key human traits. Despite the framework’s broad conceptual appeal however, empirical evidence is often perceived as limited to a few key examples like lactase persistence. We argue this apparent gap between theoretical appeal and empirical evidence stems [...]
Cultural integration of invasive species
Published: 2024-09-03
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Health and Protection, Environmental Studies, Natural Resources and Conservation, Sustainability
Many invasive non-native species gradually become embedded within local cultures. Such species can increasingly be perceived by society as familiar or even native elements of the social-ecological system and become an integral part of local cultures. Here, we explore this phenomenon and refer to it as the cultural integration of invasive species. Although culturally integrated species can [...]
Community-ecosystem interactions control plant biodiversity change before and after mangrove restoration.
Published: 2024-08-28
Subjects: Ecology and Evolutionary Biology
Restoring biological diversity and ecosystem function requires understanding how introduced species interact with one another and their environments. The most prevalent and challenging scenarios involve multiple invasive species whose traits feedback through ecosystem processes. However, research into these systems often focuses on either community dynamics or ecosystem properties, rather than [...]
Quantifying Carbon Sequestration and Ecosystem Enhancement Through Novel Phytoplankton Farming Techniques
Published: 2024-08-28
Subjects: Ecology and Evolutionary Biology, Life Sciences
Phytoplankton farming emerges as a critical nature-based solution to address the intertwined crises of climate change and marine ecosystem degradation. As foundational drivers of oceanic carbon cycling, phytoplankton generate ~50% of Earth’s oxygen and sequester 10–20 billion metric tons of CO₂ annually through the biological carbon pump . This study develops scalable cultivation techniques to [...]
Rethinking Environmental Impact Assessment for nature positive development
Published: 2024-08-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Achieving nature positive development within existing regulatory frameworks will be challenging. Halting and reversing biodiversity loss requires restoration and enhancement of ecosystems alongside a fundamental shift in how we value biodiversity and assess quantifiable improvements. Environmental Impact Assessments (EIAs) focussed on mitigating negative impacts do not promote positive outcomes – [...]
Thermal performance curves, activity and survival in a free-ranging ectotherm
Published: 2024-08-28
Subjects: Ecology and Evolutionary Biology, Physiology
Temperature profoundly influences the distribution and diversity of ectotherms, yet in natural settings, interactions between environmental temperatures, behaviour, physiological function and the influence of these factors on individual survival remain poorly understood. In particular, it is unclear as to how trade-offs between these factors are optimised in wild, free-ranging species. We [...]
Quantifying disturbance effects on ecosystem services in a changing climate
Published: 2024-08-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Disturbances, such as hurricanes, fires, droughts, and pest outbreaks, can cause major changes in ecosystem conditions that threaten nature’s contributions to people (ecosystem services). However, approaches to assess these impacts on diverse services under climate change are rare. To advance such efforts, we build on the accelerating research on disturbance ecology and ecosystem services to [...]
Experimental comparison of defence behaviour against different avian top predators in an intraguild prey
Published: 2024-08-26
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Ornithology
The loss of top predators has been shown to lead to drastic changes in community structure. An important part of this is the shift in behaviour of other species. The understanding of such changes is scarce because recordings of behavioural reactions towards lost species are rarely done. This is important for predators experiencing predation pressure themselves, known as intraguild predation. [...]
IUCN Red List of Ecosystems, Mangroves of the Tropical Southwestern Pacific
Published: 2024-08-14
Subjects: Ecology and Evolutionary Biology, Life Sciences
Mangroves of the Tropical Southwestern Pacific are a regional ecosystem subgroup (level 4 unit of the IUCN Global Ecosystem Typology). It includes the marine ecoregions of Central and Southern Great Barrier Reef, Coral Sea, Fiji Islands, New Caledonia, Tonga Islands, Torres Strait Northern Great Barrier Reef, and Vanuatu. The Tropical Southwestern Pacific province mapped extent in 2020 was 874.0 [...]
Experimental evidence that phenotypic evolution but not plasticity occurs along genetic lines of least resistance in homogeneous environments
Published: 2024-08-12
Subjects: Ecology and Evolutionary Biology, Life Sciences
Genetic correlations concentrate genetic variation in certain directions of the multivariate phenotype. Adaptation and, under some models, plasticity is expected to occur in the direction of the phenotype containing the greatest amount of genetic variation (gmax). However, this may hinge upon environmental heterogeneity, which can affect patterns of genetic variation. I use experimental evolution [...]
The Architecture of Theory and Data in Microbiome Design: towards an S-matrix for microbiomes
Published: 2024-08-10
Subjects: Ecology and Evolutionary Biology, Life Sciences
Designing microbiomes for applications in health, bioengineering, and sustainability is intrinsically linked to a fundamental theoretical understanding of the rules governing microbial community assembly. Microbial ecologists have used a range of mathematical models to understand, predict, and control microbiomes, ranging from mechanistic models, putting microbial populations and their [...]
Inductive link prediction facilitates the discovery of missing links and enables cross-community inference in ecological networks
Published: 2024-08-02
Subjects: Ecology and Evolutionary Biology
Predicting species interactions (links) within ecological networks is crucial for advancing our understanding of ecosystem functioning and responses of communities to environmental changes. Transductive link prediction models are often used but are constrained by sparse, incomplete data and are limited to single networks. We address these issues using an inductive link prediction (ILP) approach. [...]
Assembly Graph as the Rosetta Stone of Ecological Assembly
Published: 2024-08-02
Subjects: Ecology and Evolutionary Biology, Life Sciences
Ecological assembly---the process of ecological community formation through species introductions---has recently seen exciting theoretical advancements across dynamical, informational, and probabilistic approaches. However, these theories often remain inaccessible to non-theoreticians, and they lack a unifying lens. Here, I introduce the assembly graph as an integrative tool to connect [...]
An integrated population modelling workflow for supporting mesopredator management

Subjects: Applied Statistics, Biodiversity, Biostatistics, Ecology and Evolutionary Biology, Longitudinal Data Analysis and Time Series, Natural Resources and Conservation, Population Biology, Statistical Methodology, Statistical Models, Survival Analysis, Terrestrial and Aquatic Ecology, Zoology
Expanding populations of mesopredators threaten biodiversity and human health in many ecosystems across the world. Lethal control through harvest is commonly implemented as a mitigation measure, yet its effects on mesopredator population dynamics in interaction with compensatory mechanisms and environmental conditions has rarely been assessed quantitatively due to data constraints. Recent [...]
Evolutionary rescue by aneuploidy in tumors exposed to anti-cancer drugs
Published: 2024-07-31
Subjects: Ecology and Evolutionary Biology, Evolution, Genetics, Life Sciences
Evolutionary rescue happens when a population survives a sudden environmental change that initially causes the population to decline toward extinction. A prime example of evolutionary rescue is the ability of cancer to survive exposure to treatment. One evolutionary mechanism by which a population of cancer cells can adapt to chemotherapy is aneuploidy. Aneuploid cancer cells can be fitter in an [...]
