Reduced levels of relatedness indicate that great-tailed grackles disperse further at the edge of their range
Published: 2024-12-19
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences, Population Biology
It is generally thought that behavioral flexibility, the ability to change behavior when circumstances change, plays an important role in the ability of a species to rapidly expand their geographic range. However, it is an alternative non-exclusive possibility that an increase in the amount of available habitat can also facilitate a range expansion. Great-tailed grackles (*Quiscalus mexicanus*) [...]
Environmental RNA mitigates fish ghosts related to fish feeds for aquaculture in molecular ecological survey in a bay.
Published: 2024-12-19
Subjects: Aquaculture and Fisheries Life Sciences, Biodiversity, Genomics, Terrestrial and Aquatic Ecology
The use of environmental DNA for molecular ecological surveys has become widely utilized in ecological assessments of various water environments, from rivers to coastal and marine areas. However, it is important to consider the scenarios of potential contamination of environmental nucleic acids in interpreting the results. In this study, we analyzed the fish species present in the feed that may [...]
Forecasting patterns of shifting biodiversity refuges in an increasingly flammable world
Published: 2024-12-19
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
In a warming and rapidly changing world, biodiversity is increasingly threatened by more frequent, severe, and larger fires. Variation in the life history attributes and habitat preferences of species mean that they may be affected differently by fire, and hence, decision makers must account for this. Understanding how fire affects the distribution of important areas of habitat and refuges for [...]
A phylogenetic sectional taxonomy of Leucheria Lag. (Asteraceae; Nassauvieae)
Published: 2024-12-19
Subjects: Biodiversity, Life Sciences
Multiple molecular phylogenetic analyses have demonstrated that the genus Polyachyrus Lag. (8 spp.) is phylogenetically nested among four well-supported but unnamed monophyletic lineages of the genus Leucheria Lag. (28-46 spp.; Asteraceae; Nassauvieae). In order to facilitate reference to these lineages per current phylogenetic taxonomic and botanical nomenclatural conventions, a phylogenetic [...]
Cognitive processes are robust to early environmental conditions in two lizard species
Published: 2024-12-19
Subjects: Life Sciences
Animals must acquire new information through learning to adjust their behavior adaptively. However, learning ability can be constrained by conditions experienced during early development, when the brain is especially susceptible to environmental conditions. For example, temperature can result in phenotypically plastic adjustments to growth, metabolism, and learning in ectotherms. In vertebrates, [...]
A dataset for benchmarking molecular identification tools based on genome skimming
Published: 2024-12-19
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences
Genome skimming is an emerging tool allowing for scalable DNA barcoding efforts for numerous biodiversity science applications. Despite its growing importance, there are few standardized datasets for benchmarking genome skimming tools, making it challenging to evaluate new methods (e.g., using machine learning), and comparing to existing ones (e.g., conventional barcoding loci derived from [...]
Selecting indicators to track progress towards the Global Biodiversity Framework: A case study of Quebec's 2030 Nature Plan
Published: 2024-12-19
Subjects: Biodiversity, Ecology and Evolutionary Biology
Selecting biodiversity indicators to report national and subnational progress towards the Kunming-Montreal Global Biodiversity Framework (GBF) is a major challenge, one made even more urgent by the fast approaching 2030 targets. To efficiently identify appropriate indicators, the selection process must be streamlined, while remaining transparent, effective, and with the active engagement of [...]
Parasite traits shape the association between forest loss and infection: A global meta-analysis
Published: 2024-12-18
Subjects: Life Sciences
Forest loss can affect host–parasite dynamics, posing risks to wildlife and human health. Most work has investigated how host traits moderate associations between forest loss and prevalence, but the role that parasite traits play is less understood. We synthesized parasite prevalence and parasite trait data from publicly available databases representing carnivores, ungulates, and primate host [...]
Construction costs and tradeoffs in carnivorous pitcher plant leaves: towards a pitcher leaf economic spectrum
Published: 2024-12-18
Subjects: Life Sciences
Abstract • Background Leaf economic theory holds that physiological constraints to photosynthesis have a role in the coordinated evolution of multiple leaf traits, an idea that can be extended to carnivorous plants occupying a particular trait space that is constrained by key costs and benefits. Pitcher traps are modified leaves that may face steep photosynthetic costs: a high-volume, [...]
From Vegetation to Vulnerability: Integrating Remote Sensing and AI to Combat Cheatgrass-Induced Wildfire Hazards in California
Published: 2024-12-18
Subjects: Computational Engineering, Environmental Indicators and Impact Assessment
Wildfire risk is on the rise around the world. In places like California, this risk is further instigated by the invasive species cheatgrass (Bromus tectorum). Cheatgrass is highly flammable and benefits from wildfires, allowing it to replace native plant communities. Through increasing both the intensity and the frequency of wildfires, it endangers not only its natural environment but also human [...]
Cryptic ontogenetic changes in the ventral coloration of a colour polymorphic wall lizard (Podarcis muralis)
Published: 2024-12-18
Subjects: Life Sciences
Many animals undergo irreversible ontogenetic colour changes (OCCs), yet these changes are often overlooked despite their potential ethological relevance. The problem is compounded when OCCs involve wavelengths invisible to humans. Wall lizards can perceive ultraviolet (UV) light, and their conspicuous ventral and ventrolateral coloration —including UV-reflecting patches— likely serves social [...]
Intraspecific variation and detectability of iridescence in the dorsal coloration of a wall lizard
Published: 2024-12-18
Subjects: Life Sciences
Iridescence refers to the optical property of surfaces for which reflected wavelengths depend on viewing geometry. Although iridescence underlies some of the most striking animal colours, the sensory stimulation elicited by iridescent spectral shifts in relevant observers has seldom been explored. Wall lizards often show substantial intraspecific colour variation, which may influence the [...]
Amazonian and Andean tree communities are not tracking current climate warming
Published: 2024-12-18
Subjects: Life Sciences
Climate change is shifting species distributions, leading to changes in community composition and novel species assemblages worldwide. However, the responses of tropical forests to climate change across large-scale environmental gradients remain largely unexplored. Using long-term data over 66,000 trees of more than 2,500 species occurring over 3,500 m elevation along the hyperdiverse [...]
Wood density variation across an Andes-to-Amazon elevational gradient
Published: 2024-12-17
Subjects: Biodiversity, Ecology and Evolutionary Biology, Forest Sciences, Life Sciences
1. Understanding how functional traits are related to species diversity and ecosystem properties is a central goal of ecology. Wood density is a trait that integrates many aspects of plant form and function and is highly variable among species. Previous studies of wood density across elevational gradients have been based on limited sampling and have reported declines with increasing elevation, [...]
Improving Aboveground Biomass Estimates with 3D Tree Crown Parameters from UAV-LS in Beech Forests
Published: 2024-12-17
Subjects: Forest Management, Forest Sciences, Life Sciences
Accurate estimates of aboveground biomass (AGB) are essential for forest policies to reduce carbon emissions. Unmanned aerial laser scanning (UAV-LS) offers unprecedented millimetric detail but is underutilized in monitoring broadleaf Mediterranean forests compared to coniferous ones. This study aims to design and evaluate a procedure for AGB estimates based on the predictive power of crown [...]
