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 [...]

Using seed germination as a proxy of restoration success
Published: 2025-01-16
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Ecological restoration of post-mining landscapes is critical to mitigating the environmental impacts of extraction activities. This study compares the effectiveness of geomorphic restoration (GR) versus conventional restoration (CR) techniques in improving soil water availability and seed germination dynamics in the Fortuna quarry, a Mediterranean post-mining site in Spain. Soil water content [...]
Reproductive consequences of mate retention and divorce in a short-lived migratory passerine
Published: 2025-01-16
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Life Sciences
In socially monogamous birds, pair bond duration varies widely across species, from single-breeding associations to long-lasting, multi-year bonds. Studies on mate retention and divorce have predominantly focused on long-lived species, while research in short-lived and migratory species is limited. Consequently, the fitness consequences of divorce or remating in these species remain unclear. [...]
A concept highlighting the interplay between α-niche evolution and β-niche evolution in bacteria
Published: 2025-01-16
Subjects: Life Sciences
When bacteria evolve new traits, this can be either to our benefit or harm. Trying to steer and control evolution in desirable directions is a major, but daunting aspiration of recent research. In natural systems and complex communities, however, it is repeatedly observed that trait evolution regularly deviates from predicted avenues suggested by in vitro experimentation on monocultures. This [...]
Integrating Morphological and Molecular Data for Resolving Lucinidae (Bivalvia) Phylogenies: Implications for Taxonomy and Fossil Inclusion
Published: 2025-01-13
Subjects: Life Sciences
Lucinidae, an ancient clade of chemosymbiotic bivalves dating back to the Late Jurassic, have undergone changing taxonomic classifications. Older morphology-based classifications conflict with recent molecular phylogenies. Current taxonomies rely on molecular data, limiting phylogenetic placement to extant taxa with available molecular data. To better understand lucinid evolutionary history, a [...]
Strategies to transform natural resource extension with iNaturalist and engage the public in biodiversity conservation
Published: 2025-01-13
Subjects: Biodiversity, Education, Life Sciences
Participatory citizen science is an increasingly popular tool which provides non-formal education and learning activities. iNaturalist—a free open-access—participatory citizen science platform provides a place to engage the public in natural resource programming. Here, we explore practical applications for integrating iNaturalist into extension programming. We highlight two approaches: (1) [...]
The implementation of network meta-analysis in Ecology; a case study using crop yield data
Published: 2025-01-13
Subjects: Agriculture, Biodiversity, Life Sciences, Natural Resources and Conservation, Natural Resources Management and Policy
Network meta-analysis (NMA) is a method commonly used in medical research that allows for the comparison of multiple interventions in a single, coherent analysis. In this study, we explore how NMA can be applied in ecological studies – specifically, in comparing the effectiveness of multiple interventions in field experiments. Our study aims to provide a general and non-technical introduction of [...]
The origin of life; the first self-replicating molecules were RNA nucleotides.
Published: 2025-01-13
Subjects: Life Sciences
Difficulty to efficiently synthesize RNA nucleotides by joining their subunits in modern labs under simulated prebiotic Earth environments leads us to propose an alternative process by cross complimentary self-replication with help of abiotic catalysts such as minerals which are known to be good catalysts and certainly existed on prebiotic Earth. The process took place in areas with cyclic [...]
Biocultural Families and Leaders: New Metaphors, Methods and Members for Environmental Connectivity in Unama'ki
Published: 2025-01-09
Subjects: Arts and Humanities, Life Sciences, Social and Behavioral Sciences
In this community inquiry into the importance of connectivity to the newly established Kluskap Indigenous Protected and Conserved Area (IPCA) in Unama'ki (Cape Breton), our team partnered with local knowledge-holders to develop locally appropriate definitions and metaphors for connectivity along with methodologies for understanding and visualizing its concrete manifestations, including by [...]
Biodiversity research requires more motors in the mud, air and water
Published: 2025-01-09
Subjects: Life Sciences
Human activities have accelerated species extinctions, causing a rapid biodiversity decline. Simultaneously, recent advancements in artificial intelligence and autonomous systems offer transformative potential for biodiversity research. Uncrewed vehicles—such as aerial drones, ground robots, and underwater vehicles—equipped with high-resolution sensors enhance ecosystem monitoring with [...]
Population structure plays a key role in community stability
Published: 2025-01-09
Subjects: Applied Mathematics, Ecology and Evolutionary Biology, Life Sciences, Physical Sciences and Mathematics
The relationship between ecosystem complexity and stability remains unresolved and a mechanistic explanation for the stunning levels of biodiversity observed in communities and ecosystems is still lacking. Recent work has shown that differences in the foraging capacity and predation risk of juveniles versus adults within populations result in larger, more complex communities than predicted by [...]

Phenological Plasticity and Its Thermal Determinants in Common Songbirds across Europe
Published: 2025-01-07
Subjects: Ecology and Evolutionary Biology, Life Sciences
Phenological plasticity—the ability of organisms to adjust breeding timing in response to environmental variability —is the primary mechanism for seasonal organisms as it enables to synchronize their life cycles with seasonal resource availability. Theory predicts that phenological plasticity should vary among populations because of environmental heterogeneity, and among species because of [...]
