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 [...]
Multiplayer videogames to analyze behavior during ecological interactions
Published: 2025-02-10
Subjects: Life Sciences
Behavior shapes population and community dynamics through feedbacks with habitat configuration and interaction networks. Work on this interplay includes longitudinal surveys, experiments, and models. Multiplayer online videogames foster real-time interactions among lots of players in virtual spaces. Data from these games could complement theoretical and empirical work but research on them is only [...]
Geography, taxonomy, extinction risk and exposure of fully migratory birds to droughts and cyclones
Published: 2025-02-10
Subjects: Ecology and Evolutionary Biology, Life Sciences
Anthropogenic climate change is predicted to drive unprecedented increases in the frequency and intensity of extreme climatic events, such as drought and cyclones. The impacts of these events on fully migratory species could be particularly severe and have cascading effects on the functioning of many ecosystems. We explore the relationships between geography, taxonomy, extinction risk and the [...]
Monogenea on exotic Indian freshwater fish. 8. Co-translocation of Cichlidogyrus tilapiae (Monogenea, Dactylogyridae) with pindani Chindongo socolofi (Cichliformes, Cichlidae), the first report of this parasite genus in India

Subjects: Aquaculture and Fisheries Life Sciences, Life Sciences, Parasitology, Terrestrial and Aquatic Ecology, Zoology
Chindongo socolofi (Cichliformes, Cichlidae) is a popular freshwater ornamental fish from Lake Malawi in Africa. Although identifying parasites associated with the global ornamental trade is critical for developing biosecurity practices, little is known about the parasite fauna of C. socolofi. Therefore, this study sought to determine what monogenean parasites C. socolofi harbours in India. Adult [...]
