Revisiting the copepod diversity of Indian Sundarbans through estimation of carcasses
Published: 2025-05-21
Subjects: Life Sciences
Diversity assessment of plankton traditionally considers species richness and abundance, overlooking the vital state of individuals (i.e., alive or dead). This study aimed to integrate the vital state of zooplankters into diversity indices, using the copepods of the Indian Sundarbans (IS) as an example community. It was hypothesized that when carcasses estimation (CE) is incorporated diversity [...]
Filling Monitoring Gaps for Data-deficient Species Using Annual Occupancy Predictions from Co-occurrence Models
Published: 2025-05-21
Subjects: Biodiversity, Ecology and Evolutionary Biology, Entomology, Life Sciences
Fragmented surveys and limited monitoring exclude most invertebrate species from conservation policy. We present a framework that generates annual occupancy predictions using species distribution models (SDMs) to reconstruct missing trends—not to extrapolate trends, but to fill them in (the fill-in approach). Instead of filtering poor-data regions and years or relying on static environmental [...]
Toward Ecological Forecasting of West Nile Virus in Florida: Insights from Two Decades of Surveillance
Published: 2025-05-20
Subjects: Environmental Monitoring, Medicine and Health Sciences, Physical Sciences and Mathematics, Statistical Models, Virus Diseases
West Nile Virus (WNV) is the leading cause of mosquito-borne disease in the United States, yet transmission activity remains difficult to predict. This study used 20 years of digitized WNV seroconversion data from 526 sentinel chicken coops across Florida to develop spatiotemporal models with landscape and climate variables to predict WNV seroconversion at monthly and seasonal timescales. We [...]
NextGeneration specimen digitization: The international herbarium community goes spectral!
Published: 2025-05-20
Subjects: Life Sciences
1. Spectral reflectance measured from herbarium specimens represents a vast source of plant phenotypic and functional trait data. 2. The potential to capture data from specimens to enhance knowledge of plant function and taxon identification has inspired many laboratories worldwide to initiate next-generation spectral digitization from specimens. 3. Combining these datasets into a coordinated [...]
Multimodal data integration to model, predict, and understand changes in plant biodiversity: a systematic review
Published: 2025-05-16
Subjects: Life Sciences
The integration of multimodal data to analyze, model, and predict changes in plant biodiversity is critical for addressing global conservation challenges. This systematic review examines the current landscape of plant biodiversity data, focusing on the identification, classification, and evaluation of key open-access data sources and integration methodologies. We highlight the strengths and [...]
Nestbox use is linked to increased paternity loss in infected blue tits, but not great tits
Published: 2025-05-16
Subjects: Life Sciences
Host-parasite interactions and reproductive strategies are critical aspects of avian life history, yet knowledge of their interplay in the context of nesting site microhabitat, in particular between natural and artificial nesting sites, is lacking. The choice of nesting site is critical for successful breeding, by ensuring protection from predators and a suitable environment for incubation and [...]
Disordered systems in community ecology: a tutorial
Published: 2025-05-16
Subjects: Ecology and Evolutionary Biology, Other Physical Sciences and Mathematics
A basic fact of community ecology is that most ecosystems are comprised of many species and processes. Mathematical models trying to capture these ingredients and explain empirical phenomena usually face the problem of having vast numbers of unknown parameters and uncertain assumptions. It is not obvious when such mathematical models can truly be quantitatively predictive, or even conceptually [...]
Oxygen supersaturation has negligible effects on warming tolerance in aquatic ectotherms
Published: 2025-05-16
Subjects: Aquaculture and Fisheries Life Sciences, Ecology and Evolutionary Biology, Marine Biology
Under the midday sun when photosynthesizers are producing oxygen, shallow aquatic ecosystems can become supersaturated with oxygen (>100% air saturation) while they simultaneously peak in water temperature. It has been suggested that oxygen supersaturation could protect water-breathing animals from mortality during heatwaves because of the potential role of oxygen in governing thermal [...]
Reply to: Maximising time-series inclusion reduces geographic and taxonomic biases in the Living Planet Index
Published: 2025-05-16
Subjects: Biodiversity
In their recent communication, "Maximising time-series inclusion reduces geographic and taxonomic biases in the Living Planet Index" (https://doi.org/10.32942/X2M33C), McRae et al. have raised objections to our study, "Mathematical biases in the calculation of the Living Planet Index lead to overestimation of vertebrate population decline" (https://doi.org/10.1038/s41467-024-49070-x). In this [...]
State-space models and inference approaches for aquatic animal tracking with passive acoustic telemetry and biologging sensors
Published: 2025-05-15
Subjects: Behavior and Ethology, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
1. Passive acoustic telemetry systems are widely deployed to track animals in aquatic environments. However, investments in integrative methods of data analysis have remained comparatively limited, with current workflows typically considering individual movements separately from space use, home ranges and residency. 2. This review presents a unifying perspective that bridges this divide. We [...]
Disordered and Partially Structured Models in Community Ecology: What are they? And how do we use them?
Published: 2025-05-15
Subjects: Life Sciences, Physical Sciences and Mathematics
Community ecology describes how species interact with each other and with their environment. In nature, processes can be very complex because they involve hundreds to thousands of species interacting with each other in complex environmental landscapes. Classical approaches that have provided key insights have largely focused on the study of tractable subsets of species and patches, but these do [...]

The burden of a failed error culture in biologging
Published: 2025-05-15
Subjects: Ecology and Evolutionary Biology, Life Sciences
Driven by technological advancements and reduced costs, biologging has seen a rapid growth transforming the study of animal behaviour and ecology providing unprecedented insights into wildlife, aiding conservation efforts and ecological research. However, in the wake of the rapid growth loom pressing ethical and methodological challenges, including a lack of error reporting, inconsistent [...]
Transgenerational plasticity to warming decreases nutrient release by a keystone grazer
Published: 2025-05-15
Subjects: Life Sciences
Increasing temperatures as a result of global climate change can alter the physiology of organisms via selection for tolerant genotypes and individual-level plasticity. Organisms experiencing thermal stress can not only modify their own physiological expression, but also those of future generations; i.e. transgenerational plasticity (TGP). While warming triggered TGP is well documented, its [...]
A geographical database of Iberian peatland and swob records
Published: 2025-05-15
Subjects: Physical and Environmental Geography
Recent efforts have compiled distribution data on Iberian Peninsula peatlands, however, the criteria used to characterise these ecosystems have often been derived from regions where peatlands are more extensive and typically occur under wetter climatic conditions. As a result, many peat-accumulating wetlands in this region were overlooked. Identifying and improving the distribution mapping of [...]
