IUCN Red List of Ecosystems: Coral Reefs of the Eastern Tropical Pacific
Published: 2026-10-22
Subjects: Life Sciences
Coral reefs in the Eastern Tropical Pacific (ETP), covering 140 km² (0.04% of the total global coral reef extent), are under increasing climate and anthropogenic threats. Coral reef development and species distribution in the ETP are conditioned by the characteristic isolation of the region and its strong environmental variability, including El Niño-Southern Oscillation (ENSO) events and [...]
IUCN Red List of Ecosystems: Coral Reefs of the Pacific
Published: 2026-10-22
Subjects: Life Sciences
Coral reefs of the Pacific region extend across approximately 30°N to 30°S, covering roughly 35 500 km2. They range from tropical waters of Papua New Guinea in the West to subtropical latitudes, such as Southeastern Pitcairn or Northern Hawaii borders. This encompasses 21 coral reef ecoregions as defined by the Marine Ecoregions Of the World (MEOW) and Marine and Coastal Biodiversity Management [...]
IUCN Red List of Ecosystems: Coral Reefs of the Western Indian Ocean
Published: 2026-10-22
Subjects: Life Sciences
Western Indian Ocean (WIO) coral reefs extend across the East African coastline from Somalia to South Africa, and eastward to include the Îles Éparses and island states of Madagascar, the Comoros, Seychelles and Mauritius, and the French territories of Mayotte and Réunion. The total mapped area of photic coral reef ecosystems is approximately 8090 km², representing approximately 4.5 % of the [...]
From Risk to Application: What Critically Endangered means for the world's coral reefs
Published: 2026-10-22
Subjects: Biology, Life Sciences
The first global risk assessment of coral reef ecosystems has found all fully assessed, shallow-water (photic) coral reef ecosystems are at an extremely high risk of ecological collapse in the next 50 years. This Critically Endangered risk assignment under the Red List of Ecosystems (RLE) applies to 122 of the 127 coral reef ecosystems (ecoregions) and was assessed by regional expert teams, [...]
Gene duplications potentiate adaptive evolution of complex traits
Published: 2026-10-21
Subjects: Evolution
Much of extant genetic material is known to have resulted from earlier genetic duplications. On this basis, gene duplications are widely recognized as a key factor in the evolution of organismal complexity --- both in producing novel adaptations (i.e., neofunctionalization) and in accumulating functional specialization (i.e., subfunctionalization). However, across the tree of life, no ready [...]
Synergistic phenology and range shifts in boreal butterflies are controlled by species' overall response capacity
Published: 2026-10-21
Subjects: Biodiversity, Population Biology
Species track climate warming through shifts in both phenology and geographic distributions, but the strength of association between these responses remains poorly understood. Although recent research points to a tendency of species to shift across either the temporal or spatial gradient, there is no comprehensive understanding of how generalizable these phenology and range shifts are and whether [...]
The role of long-distance dispersal for community dynamics of fungi
Published: 2026-10-21
Subjects: Biodiversity, Population Biology
Realized dispersal ability of wind-dispersing fungi in natural conditions remains poorly understood. Here, we study how climate, habitat type and long-distance dispersal jointly structure fungal communities and how their effects vary between species that have different morphological and life history traits. We integrate global fungal (spores and other organismal material) occurrence data [...]
Functional gene content of fungi in a pine needle disease system largely reflects their phylogeny
Published: 2026-10-21
Subjects: Bioinformatics, Computational Biology, Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Evolution, Forest Sciences, Genetics, Genetics and Genomics, Genomics, Life Sciences, Microbiology, Other Ecology and Evolutionary Biology, Pathogenic Microbiology, Plant Pathology, Plant Sciences
Background: Fungi recovered from diseased host tissue can differ substantially in functional gene content, but interpreting that variation requires knowing how it relates to evolutionary history. Results: We assembled and annotated genomes for 67 fungi cultured from pine needles with symptoms of brown spot needle blight and compared them with 13 reference genomes, including established pine [...]
Fair-weather friends: Group size boosts reproduction in wet, cool years in a cooperative breeder
Published: 2026-10-21
Subjects: Life Sciences
Climate change is altering global temperature and rainfall patterns, with measurable impacts on reproduction and population persistence. These effects are pronounced in dryland ecosystems that are characterized by high temperatures, and low, but highly variable rainfall. Cooperatively breeding species (where helpers provide parental care to other group members’ offspring) are common in drylands, [...]
The social environment shapes fitness through indirect genetic effects in spotted hyenas
Published: 2026-10-21
Subjects: Life Sciences
Additive genetic variance in fitness determines the rate of adaptive evolution. Yet, estimates from wild populations often exceed observed rates of contemporary evolution and realised population growth rates, suggesting that important sources of variation may remain unaccounted for. One important source of variation rarely fully accounted for is the social environment, because social interactions [...]
Latitude and evolutionary history shape the global distribution of migratory butterflies
Published: 2026-10-21
Subjects: Life Sciences
Hundreds of butterfly species migrate globally. Seasonal migration allows butterflies track suitable environments across large distances, yet global distribution patterns and the processes that shape them remain poorly understood. Here, using season-specific habitat suitability maps for 426 migratory butterfly species, we assess how morphological traits, environmental conditions and evolutionary [...]
A Wrinkle in Space-Time: Spatial machine learning uncovers stage-specific drivers and hidden hotspots of illegal wildlife trade
Published: 2026-10-21
Subjects: Environmental Studies
The illegal wildlife trade (IWT) persists despite intervention, demanding new approaches to allocate limited prevention and enforcement resources more effectively. Spatial machine learning has been applied to IWT for this purpose, but mainly along one dimension – place. We extend this to simultaneously address place, species, and time, applying machine learning to participatory mapping data [...]
The Doñana Digital Twin: integrating heterogeneous data into iterative, mechanistically grounded forecasts of biodiversity change
Published: 2026-10-20
Subjects: Biodiversity, Biology, Integrative Biology, Population Biology, Terrestrial and Aquatic Ecology
Natural ecosystems are increasingly impacted by multiple global-change drivers, and these impacts propagate non-linearly from individuals to populations and to communities. To anticipate ecological change under such complexities and mitigate negative impacts, we require integrated, mechanistically-grounded approaches to prediction. For mitigation strategies to be adaptive, predictions must also [...]
A common benchmark for Aedes albopictus phenological models reveals surveillance data, not model complexity, as the limiting factor
Published: 2026-10-20
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences
Forecasting the seasonal dynamics of Aedes albopictus, a highly invasive arbovirus vector now established across much of Europe, is a growing public health priority. Numerous mechanistic and correlative models have been developed over the last two decades, but largely in isolation, each calibrated and validated against its own data, which has prevented any assessment of where predictive capacity [...]
Linguistic Group Marking as an Emergent Phenomenon
Published: 2026-10-20
Subjects: Demography, Population, and Ecology, Ecology and Evolutionary Biology, Social and Behavioral Sciences
This paper examines how linguistic group marking can emerge from the interaction between social ecology, inferential cognition, and cultural transmission. An agent-based model (ABM) simulates interactions within a structured population where agents use domain-general inference and social learning to interpret and adopt linguistic variants. The model implements a mechanism in which uncertainty [...]
