Climate change amplifies extinction risk of a subshrub in anthropogenic landscapes
Published: 2024-09-06
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
In most ecosystems, the increasingly strong effects of climate change on biodiversity co-occur with other anthropogenic pressures, most importantly land-use change. However, many long-term studies of population dynamics focus on populations monitored in protected areas, and our understanding of how climate change will affect population persistence under anthropogenic land use is still limited. To [...]
Gene-culture coevolution: A broader evolutionary perspective
Published: 2024-09-05
Subjects: Anthropology, Biological and Physical Anthropology, Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Genomics, Social and Behavioral Sciences
Gene-culture coevolution (GCC) stands out among approaches to human evolution for its ambitious synthesis of biological and social sciences. Combining insights from cultural evolution and human genetics, it has been invoked to explain the evolution of many "species-defining" human traits, from language to large-scale cooperation. However, despite its broad conceptual appeal, empirical evidence [...]
Cultural inception of invasive species
Published: 2024-09-02
Subjects: Biodiversity, Ecology and Evolutionary Biology, Environmental Health and Protection, Environmental Studies, Natural Resources and Conservation, Sustainability
1. Many invasive alien species gradually become embedded within local cultures. Such species can increasingly be perceived by society as familiar and native elements of the social-ecological system and as integral parts of local cultures. 2. Here, we explore this phenomenon and define it as cultural inception. Cultural inception can greatly hinder our ability to successfully manage invasive [...]
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
Farming phytoplankton has significant potential in addressing global warming and enriching marine ecosystems. Moreover, phytoplankton is more or less the ocean's small powerhouse, with the ability to sequester carbon, produce oxygen, and support food webs for marine ecosystems. To explore this potential, we developed new cultivation techniques to increase phytoplankton populations [...]
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 – [...]
Maximum movement performance, not activity levels or thermoregulatory indices, affects survival in a free-ranging ectotherm
Published: 2024-08-27
Subjects: Ecology and Evolutionary Biology, Physiology
1. Temperature profoundly influences the distribution and diversity of ectotherms, yet in natural settings, the trade-offs between environmental temperatures, behaviour, physiological function, and how they drive individual survival, remain poorly understood. 2. To address these gaps, we generated field-based thermal performance curves, using temperature-sensitive radio transmitters and [...]
Quantifying disturbance effects on ecosystem services in a changing climate
Published: 2024-08-27
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 [...]
A top predator provokes similar defense behavior as a mesopredator 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 behavior of other species. The understanding of such changes is scarce because recordings of behavioral 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

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: 2024-08-09
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 boosts data availability and enables cross-community link prediction in ecological networks
Published: 2024-08-02
Subjects: Ecology and Evolutionary Biology
Predicting species interactions within ecological networks is vital for understanding ecosystem functioning and the response of communities to changing environments. Traditional link prediction models often fall short due to sparse and incomplete data and are limited to single networks. Here, we present a novel approach using inductive link prediction (ILP), which leverages structural [...]
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 [...]
