Repeated mitochondrial capture with limited genomic introgression in a lizard group
Published: 2025-02-19
Subjects: Ecology and Evolutionary Biology, Evolution, Genetics and Genomics, Life Sciences
Mitochondrial introgression is common among animals and is often first identified through mitonuclear discordance — discrepancies between evolutionary relationships inferred from mitochondrial DNA (mtDNA) and nuclear DNA (nuDNA). Over recent decades, genomic data have also revealed extensive nuclear introgression in many animal groups, with implications for genetic and phenotypic diversity. [...]
High-resolution habitat suitability maps for all widespread Italian breeding bird species
Published: 2025-02-18
Subjects: Life Sciences, Ornithology, Other Ecology and Evolutionary Biology
Tackling the current global biodiversity crisis requires spatially accurate biodiversity data to rapidly assess knowledge gaps and set conservation priorities. Obtaining accurate data across large spatial scales is often challenging, due to the massive logistical and economic requirements of large-scale surveys. Here, we provide high-resolution (0.81 to 81 km², depending on species ecology) [...]
Report on spatial sampling designs for long term biodiversity monitoring of soil biota
Published: 2025-02-18
Subjects: Life Sciences
Soil biota are extremely diverse and spatially heterogeneous. Sampling strategies that target the soil biota through metabarcoding must incorporate existing ecological theory and explicitly consider technical constraints. This report synthesizes empirical research from large-scale projects (SpaceMic, PhytOakMeter) to evaluate how spatial sampling design—specifically sample extent, number, and [...]
Spectral biology across scales in changing environments
Published: 2025-02-18
Subjects: Life Sciences
Understanding ecosystem processes on our rapidly changing planet requires integration across spatial, temporal and biological scales. We propose that spectral biology, using tools that enable near- to far-range sensing by capturing the interaction of energy with matter across domains of the electromagnetic spectrum, will increasingly enable ecological insights across scales from cells to [...]
Assessing UAV direct-seeding for tropical forest restoration: early-stage growth and cost-effectiveness
Published: 2025-02-14
Subjects: Forest Management, Life Sciences, Other Forestry and Forest Sciences
Introduction: The high cost, labor intensity, and infrastructure needs of manual tree planting limit the scale of global forest restoration. UAV-assisted direct seeding is a promising alternative, but comparative empirical data are scarce.Objectives: This study assesses UAV-assisted direct seeding as a cost-effective alternative to manual planting for tropical forest restoration by comparing [...]
Community (citizen) science as a tool to support nature’s benefits assessments in the UK: a systematic review and survey of community scientists
Published: 2025-02-14
Subjects: Life Sciences
1) Developing methods for valuing nature aim to address biodiversity and environmental crises caused by nature’s undervaluation in decision-making. However, implementing methods to assess nature’s benefits is challenging for a myriad of reasons. 2) We explored whether community science (CS) could support a more holistic assessment of nature’s benefits on a national scale using a mixed-methods [...]
Northward expansion of the thermal limit for the tick Ixodes ricinus over the past 40 years
Published: 2025-02-14
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Entomology, Life Sciences, Population Biology
The tick Ixodes ricinus is the main pathogen vector in Europe. Many speculations have been made about the effect of past climate change on the potential distribution of this ectothermic organism, despite a poor understanding of how climate change has resulted in distribution changes to date. In this study, we used a public cross-sectional dataset of I. ricinus abundance at the northern edge of [...]
The effect of habitat health and environmental change on cultural diversity and richness in animals
Published: 2025-02-13
Subjects: Life Sciences
There is increasing evidence that habitat decline via fragmentation or species loss can lead to loss of cultural diversity, complexity, or richness in non-human animals. For example, a reduction in local bird species richness leads lyrebirds to sing less complex song, while great apes living in fragmented landscapes have smaller cultural repertoires. However, the link between animal culture and [...]
Diversity and Distribution of Amphibians and Freshwater Fishes on Australian Islands
Published: 2025-02-13
Subjects: Life Sciences
Freshwater ecosystems cover less than 3% of the earth’s surface, yet support nearly 10% of all known animal species, majorly represented by freshwater fishes (69%) and amphibians (24%), both of which are highly threatened groups. Geographically isolated freshwater species, such as those inhabiting islands, are at high risk. Australia, with ~9300 islands, is home to diverse island freshwater [...]
Monitoring animal movement diversity as a component of biodiversity
Published: 2025-02-12
Subjects: Life Sciences
Animal movement is increasingly being quantified in novel ways, with high potential for integration in broad-scale efforts to monitor biological diversity. Here, we define movement diversity as a form of biodiversity measuring variation in animal movement from the level of individual animals to communities. We present a framework to develop a common language for movement diversity metrics which [...]
Individual variation in animal communication: from species averages to unique voices
Published: 2025-02-12
Subjects: Life Sciences
The comparative study of the communicative behaviour of non-human animals, especially primates, has yielded crucial insights into the evolution of human language. This research, mostly focused on the species and population level, has helped to understand the various socio-ecological factors that shape communication systems. However, despite the inherent flexibility of human communication, the [...]
Designing epigenetic clocks for wildlife research
Published: 2025-02-12
Subjects: Life Sciences
The applications of epigenetic clocks, statistical models that predict an individual's age based on DNA methylation patterns, are expanding in wildlife conservation and management. This growing interest highlights the need for field-specific design best practices. Here, we provide recommendations for two main applications of wildlife epigenetic clocks: estimating the unknown ages of individuals [...]
Location-scale Meta-analysis and Meta-regression as a Tool to Capture Large-scale Changes in Biological and Methodological Heterogeneity: a Spotlight on Heteroscedasticity
Published: 2025-02-11
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology
Heterogeneity is a defining feature of ecological and evolutionary meta-analyses. While conventional metal-analysis and meta-regression methods acknowledge heterogeneity in effect sizes, they typically as-sume this heterogeneity is constant across studies and levels of moderators (i.e., homoscedasticity). This assumption could mask potentially informative patterns in the data. Here, we introduce [...]
Variations in epifaunal assemblages among different algal species in the coastal waters of the Noto Peninsula, Japan
Published: 2025-02-10
Subjects: Life Sciences
Algal beds are biodiversity hotspots in coastal ecosystems, forming complex food webs based on seaweeds. Epifauna serve as important indicators of algal productivity and environmental change, interacting closely with their host seaweeds. This study compared the composition of epifaunal assemblages associated with different seaweed species in the Noto Peninsula, Japan, to elucidate their [...]
Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks predictive trait and classification modeling in plant biodiversity collections
Published: 2025-02-10
Subjects: Biodiversity, Bioinformatics, Botany, Ecology and Evolutionary Biology, Integrative Biology, Life Sciences
Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof-of-concept study using trait data and spectra from herbarium specimens up to 179 years old alongside data from recently dried, pressed [...]
