Bridging data silos to holistically model plant macrophenology
Published: 2025-01-30
Subjects: Ecology and Evolutionary Biology, Life Sciences, Plant Sciences
● Phenological shifts to global climate change impact ecosystem functions. There are various data sources from which spatiotemporal, and taxonomic phenological data may be obtained: mobilized herbaria, community-science initiatives, observatory networks, and remote-sensing. However, analyses conducted to date have generally relied on single sources of data, thus treating alternative data sources [...]
Why extreme events matter for species redistribution
Published: 2025-01-27
Subjects: Ecology and Evolutionary Biology
Climate change is altering species’ distributions globally. Increasing frequency of extreme weather and climate events (EWCEs), including heat waves, droughts, storms, floods, and fires, is one of the hallmarks of climate change. These events can trigger rapid shifts in species’ distributions by impacting dispersal, establishment, and survival of organisms. Despite species redistribution being [...]
Assessment of Urban Bias in Iberian Butterfly Sampling through Citizen Science Data
Published: 2025-01-24
Subjects: Entomology, Life Sciences, Research Methods in Life Sciences, Terrestrial and Aquatic Ecology
Citizen science platforms have revolutionized biodiversity monitoring by enabling large-scale data collection. However, concerns about potential biases, such as urban sampling bias, have raised questions about the quality and representativeness of these datasets. This study assesses the spatial distribution of butterfly observations collected through the citizen science platform Biodiversidad [...]
Seed biology and regeneration niche of the threatened cold desert perennial Ivesia webberi A. Gray
Published: 2025-01-22
Subjects: Life Sciences
Understanding the regeneration niche is of critical importance for the conservation of rare plants, yet species-specific information is often lacking for key components of the plant life cycle such as seed dormancy and germination. We conducted a detailed study of the regeneration niche for Ivesia webberi, a U.S. federally threatened forb that is endemic to the Great Basin Desert. Using seeds [...]
The rise and fall of proboscidean ecological diversity
Published: 2025-01-21
Subjects: Evolution
Proboscideans were keystone Cenozoic megaherbivores and present a highly relevant case study to frame the timing and magnitude of recent megafauna extinctions against long-term macroevolutionary patterns. By surveying the entire proboscidean fossil history using model-based approaches, we show that the dramatic Miocene explosion of proboscidean functional diversity was triggered by their [...]
Weather and landscape morphology drive thermal regime variation among Mývatn ponds, and implications for resident Arctic charr
Published: 2025-01-21
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Thermal stratification is common in lentic freshwater systems, and has extensive effects on ecosystem function and the interactions between aquatic organisms and their surroundings. Although thermal regimes in temperate systems are well-characterized, small arctic and subarctic lakes and ponds can have irregular thermal regimes, and the conditions leading to stratification and mixing are less [...]
Assessing migration and moulting strategy in closely related taxa based on stable isotope analysis: a population study of Balearic and Yelkouan shearwaters across their breeding range
Published: 2025-01-20
Subjects: Life Sciences
Animal migrations are unique phenomena involving mass movements of individuals, which pose significant challenges to develop conservation strategies. Migratory seabirds, particularly, face many anthropogenic threats across their distributions, and populations are declining worldwide. We provided a thorough isotopic method to characterise individual migratory patterns and identify main moulting [...]
Bottom-up interactions in age-structured stock assessment and state-space mass-balance modelling
Published: 2025-01-20
Subjects: Ecology and Evolutionary Biology, Life Sciences, Marine Biology, Population Biology
Age-structured stock assessment models are used worldwide to predict the likely impact of changing harvest on future fisheries yield. However, age-structured models ignore the impacts of predator consumption on prey survival (top-down impacts) and prey availability on predator growth (bottom-up impacts), whereas multispecies statistical catch-at-age models often incorporate top-down but not [...]
Can transcriptome size and off-target effects explain the contrasting evolution of mitochondrial vs nuclear RNA editing?
Published: 2025-01-20
Subjects: Life Sciences
Mitochondrial RNA editing has evolved independently in numerous eukaryotic lineages, where it generally restores conserved sequences and functional reading frames in mRNA transcripts derived from altered or disrupted mitochondrial protein-coding genes. In contrast to this “restorative” RNA editing in mitochondria, most editing of nuclear mRNAs introduces novel sequence variants and diversifies [...]
The BeeBiome Data Portal provides easy access to bee microbiome information
Published: 2025-01-20
Subjects: Apiculture, Bioinformatics, Environmental Microbiology and Microbial Ecology Life Sciences
Bees can be colonized by a large diversity of microbes, including beneficial gut symbionts and detrimental pathogens, with implications for bee health. Over the last few years, researchers around the world have collected a huge amount of genomic and transcriptomic data about the composition, genomic content, and gene expression of bee-associated microbial communities. While each of these datasets [...]
From Policy to Practice: Progress towards Data- and Code-Sharing in Ecology and Evolution
Published: 2025-01-20
Subjects: Ecology and Evolutionary Biology, Life Sciences
High quality research data and analytical code are essential for ensuring the credibility of scientific results, are key research outputs, and are crucial elements to facilitate reproducibility. However, in ecology and evolution (E&E) in particular, it is currently unknown how many journals have policies on data- and code-sharing for peer review purposes, or upon manuscript acceptance. [...]
What’s On The Menu Today? First Report of Nectarivory for Rhynocorus cuspidatus (Hemiptera: Reduviidae)
Published: 2025-01-17
Subjects: Life Sciences
This study reports the first observation of nectarivory in the predator reduviid Rhynocoris cuspidatus (Ribaut, 1921) in Spain. One individual of R. cuspidatus was observed sucking nectar from a Jacobeae vulgaris Gaertn flower inflorescence in a grassland meadow in Berrecil de la Sierra (Spain). Our observation suggested that R. cuspidatus can use floral resources to obtain sugar or moisture [...]
Spatial environment drives land-based social associations in a central-place foraging seabird
Published: 2025-01-17
Subjects: Animal Studies
1. Social and spatial environments shape the way individuals associate and thus impact their social network structure. However, nowhere are social and spatial mechanisms more likely to be simultaneously entangled and potentially misinterpreted than in central-place foragers. 2. We interrogated the spatial-social interface for a central-place forager in their colony. To do so we tested how the [...]
Need for a Smart Autonomous Bilge Management System: A Review
Published: 2025-01-17
Subjects: Engineering
The discharge of bilge water from ships, regulated under MARPOL regulations, presents significant environmental and operational challenges. Despite stringent regulations, compliance remains inconsistent due to economic pressures and the limitations of current monitoring technologies, which rely heavily on rudimentary automation that, in turn, depends largely on human intervention and [...]
