A chronosequence of human remains on soil microbial populations
Published: 2025-12-08
Subjects: Life Sciences, Physical Sciences and Mathematics
Surficial human decomposition produces substantial and measurable shifts in soil chemistry and microbial composition. This decade-long investigation examined temporal changes beneath surface deposited human remains and identified strong microbial and chemical responses in the first twelve to twenty four months, including decreased microbial diversity, elevated soil nutrients and sustained [...]
From patterns to predictions: A framework for the spatial epidemiology of wildlife diseases
Published: 2025-12-08
Subjects: Animal Diseases, Biodiversity, Epidemiology, Natural Resources and Conservation, Population Biology, Statistics and Probability, Veterinary Infectious Diseases, Veterinary Medicine, Veterinary Preventive Medicine, Epidemiology, and Public Health, Zoology
Wildlife diseases pose a significant threat to public health, livestock, and biodiversity conservation. In this context, spatial epidemiology offers a robust framework for elucidating disease dynamics and informing policy-making and disease management. The workflow in spatial epidemiology involves three main steps: (1) descriptive analysis of spatial dynamics; (2) exploration of the observed [...]
Habitat connectivity shapes biodiversity outcomes in Indonesia’s community-managed forests
Published: 2025-12-08
Subjects: Biodiversity, Forest Management
1. Social forestry is increasingly promoted as a means to achieve equitable resource governance while contributing to biodiversity conservation. Yet, empirical evidence on how effectively community-managed forests support biodiversity remains limited, particularly in tropical regions. 2. We assessed mammal communities in two contrasting social forestry contexts in Sumatra, Indonesia: (1) a [...]
There is no taxon-free lunch
Published: 2025-12-06
Subjects: Ecology and Evolutionary Biology
Over the last few decades, the term “taxon-free” has been widely used in paleoecological literature to highlight reasoning via ecomorphological or other functional traits of organisms as opposed to reasoning via taxonomic affiliations and phylogenetic conservatism. In practice, however, “taxon-free” inferences are very rarely free from using taxonomic information and occasionally they are even [...]
Gene expression and structural differences underpinning black and white colouration in spiders
Published: 2025-12-05
Subjects: Ecology and Evolutionary Biology, Entomology, Life Sciences
The presence of multiple colour variants within a single population, known as colour polymorphism, is a striking example of intraspecific phenotypic variation and a model for studying evolutionary processes. These processes depend on the underlying mechanisms such as the genes and pigments involved; but we currently lack such information for non-model groups such as arachnids. We examined the [...]
Butterfly abundances but not patch occupancy buffered by vegetation heterogeneity during climatic extremes
Published: 2025-12-04
Subjects: Ecology and Evolutionary Biology, Life Sciences
As extreme climatic events are becoming more frequent and intense, we need to understand what mechanisms could buffer populations from climate change impacts to ensure their persistence. Fragmented populations may be especially vulnerable to climate change, as exemplified by species with metapopulation dynamics, whose persistence is determined by a precarious balance between frequent local [...]
Identification of the Cichlid Fishes of Lake Malawi/Nyasa Part 3: Rhamphochromina and others.
Published: 2025-12-04
Subjects: Life Sciences
With an estimated 800-1000 species, the cichlid fishes of Lake Malawi represent the largest known adaptive radiation of vertebrates from common ancestry in a limited geographical area, in this case a single lake. Although they represent a major system for the study of evolution, and have considerable local economic value, the presence of so many closely-related and poorly known species presents [...]
Leveraging publicly available data to facilitate urban ecology and evolution
Published: 2025-12-04
Subjects: Life Sciences
The intensifying pace of urbanization has prompted researchers to investigate its ecological and evolutionary consequences more deeply, yet logistic and monetary challenges can impose a barrier to research. Publicly available databases offer scientists from broad backgrounds an opportunity to circumvent those barriers, enhancing participation in urban ecology and evolution. In conjunction with [...]
POLLEN ANALYSIS AS A REMOTE BIOLOGICAL SENSOR: USING MELISSOPALYNOLOGY AND SURFACE SOIL DATA FOR AN INTEGRATED LANDSCAPE SCALE VEGETATION ASSESSMENT IN SOUTH INDIA
Published: 2025-12-04
Subjects: Botany, Ecology and Evolutionary Biology, Entomology, Life Sciences, Other Ecology and Evolutionary Biology, Other Life Sciences, Other Plant Sciences, Plant Sciences
We use pollen assemblages from two sources, surface soil and bee pollen to characterize modern pollen spectra from contrasting landscapes, evaluate their potential as biological proxies complementing each other in reconstructing vegetation comprised of anemophilous and entomophilous plants. The bee pollen assemblages are from honeycombs and corbicular loads from Apis cerana and A. florea. We try [...]
African swine fever vs. COVID-19: only one virus mattered for wild boar hunting bags in Europe
Published: 2025-12-04
Subjects: Life Sciences
Wild boar (Sus scrofa) populations have been steadily increasing across Europe in the last decades, due to the synergy between landscape modifications, the ecological plasticity of the species and global warming. However, since 2014, an increasing number of these populations have also been affected by African swine fever (ASF) and have experienced increased mortality. Moreover, in 2020 and 2021, [...]
Adaptation or plasticity? Effects of temperature on metabolic rate and life-history traits in the Australian Painted Dragon lizard.
Published: 2025-12-03
Subjects: Desert Ecology, Other Ecology and Evolutionary Biology
The roles of adaptation and plasticity in shaping life-history traits have long been a subject of debate in evolutionary ecology, with the relevance of each varying by traits, populations, species, and clades. Ectothermic organisms, which obtain most of their metabolic energy from ambient heat, occupy wide geographic ranges where heat can be unevenly distributed. There is considerable potential [...]
On the spatial aggregation of condition metrics for ecosystem accounting
Published: 2025-12-03
Subjects: Applied Statistics, Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Monitoring, Life Sciences, Other Life Sciences
In face of the ongoing nature crisis, the international community is setting targets and deciding on actions to combat the current biodiversity crises. For this to be effective they need tools to accurately describe the current situation and to monitor trends in ecosystems over time. Ecosystem condition accounts (ECA) is one such tool that use variables and indicators to describe key ecosystem [...]
New species discoveries redefine global biodiversity patterns
Published: 2025-12-03
Subjects: Terrestrial and Aquatic Ecology
Global biodiversity patterns are fundamental to ecology and conservation. However, these patterns are based on incomplete and rapidly growing taxonomic knowledge, and the influence of new species discoveries on our understanding of global biodiversity remains poorly understood. Here we quantified how the discovery of terrestrial vertebrates from 1920 to 2020 has reshaped estimated global [...]
Predicting coral trends and attributing drivers of change from local to global scales
Published: 2025-12-03
Subjects: Life Sciences
Modern biodiversity monitoring programs are designed to assess abundance trends of keystone taxa and deliver scientific insights to inform decision-making and policy development. An important consideration when using these evidence-based frameworks is the quantification of uncertainty from trends, which determines the robustness of data-driven methods in detecting and attributing changes across [...]
Strengthening Community Engagement as a Pathway to Effective Forest Fire Management and Resilient Forests in Nepal
Published: 2025-12-03
Subjects: Environmental Sciences, Forest Management, Forest Sciences, Natural Resources Management and Policy
Forest ecosystems are indispensable for planetary health. They provide sustenance for around a quarter of global population. Forest fire is an important ecological disturbance; however, it can cause ecological and societal harm due to anthropogenic mismanagement and natural adversities leading to long-term socio-economic and environmental consequences. Extreme wildfire events have increased [...]
