Code review in practice: A checklist for computational reproducibility and collaborative research in ecology and evolution
Published: 2025-04-24
Subjects: Life Sciences, Social and Behavioral Sciences
Ensuring that research, along with its data and code, is credible and remains accessible is crucial for advancing scientific knowledge—especially in ecology and evolutionary biology, where the climate crisis and biodiversity loss accelerate and demand urgent, transparent science. Yet, code is rarely shared alongside scientific publications, and when it is, unclear implementation and insufficient [...]
Foliar spectral signatures reveal adaptive divergence in live oaks (Quercus section Virentes) across species and environmental niches
Published: 2025-04-24
Subjects: Life Sciences
Genomic tools have transformed our understanding of species and population genetic structure in landscapes. However, discerning the impacts of neutral and adaptive evolutionary forces remains challenging, largely due to the scarcity of tools capable of measuring a broad spectrum of phenotypic traits. We used spectroscopic data from preserved leaves to test for adaptive divergence among [...]
Large female northern pike (Esox lucius) do not connect spawning areas across a lagoon network in the southern Baltic Sea
Published: 2025-04-24
Subjects: Life Sciences
Exceptionally large individuals may serve as keystone connectors among subpopulations and habitats, a role recently demonstrated in large Atlantic cod (Gadus morhua) in Norway. To examine whether this pattern extends to other coastal fish species, we analysed capture-mark-recapture data for over 5,800 coastal northern pike (Esox lucius) and acoustic tracking data from 317 pike individuals, using [...]
The case for octopus sentience: a follow-up to Simone’s “Are octopuses sentient beings?”
Published: 2025-04-24
Subjects: Life Sciences, Marine Biology
Recently, a paper published in a Brazilian malacology online journal argued against the existence of sentience in octopuses based on disputable arguments – the presence of cannibalistic behavior, absence of sociality and parental care, short lives, size and complexity of the nervous system and intelligence. This response discusses a different perspective on the issue of octopus sentience, [...]
Understanding niche conformance in fire salamander larvae: Insights from reciprocal transplant experiments
Published: 2025-04-24
Subjects: Animal Sciences, Life Sciences, Zoology
Amphibians are in particular vulnerable to (climatic) changes in their habitat as they are highly dependent on precipitation and temperature. The larval stage can be considered the most critical life stage in the ontogeny of most amphibians as predation is very high, and larvae are restricted to their natal aquatic habitat. The same applies for larvae of the fire salamander (Salamandra [...]
MUSEUMS SHOULD CURATE BEYOND THE NATURAL: DOMESTIC BREEDS OFFER UNIQUE INSIGHT INTO EVOLUTIONARY PROCESSES & HUMAN CULTURE
Published: 2025-04-23
Subjects: Arts and Humanities, Life Sciences
This short communication proposes that natural history museums should consider expanding their mission by intensively collecting and curating domesticated, hemerophilic, and genetically engineered animals, plants, and fungi to improve the study of evolutionary biology and anthropology, as well as mitigate against future climatic and economic challenges.
Longer heatwaves disrupt bacterial communities by decoupling resistance from recovery
Published: 2025-04-22
Subjects: Life Sciences
Periodic heatwaves are increasing in duration, yet their ecological impacts on communities remain poorly understood. We experimentally tested how synthetic communities of soil Pseudomonas species respond to heatwaves of increasing duration. We used a resistance-recovery framework and growth rate-heat tolerance trade-offs to predict whether prolonged stress erodes community stability. Communities [...]
Computer Vision Models Offer Scalable Species Detection From Social Media Photographs
Published: 2025-04-22
Subjects: Life Sciences
Social media platforms have emerged as a promising source of data for biodiversity monitoring, due to the vast amounts of user-generated visual content. However, the unstructured and noisy nature of social media data poses challenges for accurate species identification. Foundation vision models present an innovative methodology for identifying a large diversity of species from photographs, [...]
Linking Pattern to Process in Metacommunities: Challenges and Opportunities
Published: 2025-04-21
Subjects: Life Sciences
Ecological communities, and especially metacommunities, are complex and dynamic entities. Resolving the processes and mechanisms that shape these systems remains a central challenge in ecology. This challenge is compounded by the increasing entanglement of mechanisms, processes, and emergent patterns of biodiversity as scales of space, time, and biological organization expand. Here, we define and [...]
BOLDistilled: Comprehensive but compact DNA barcode reference libraries
Published: 2025-04-21
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Life Sciences
Advances in DNA sequencing technology have stimulated the rapid uptake of protocols—such as eDNA analysis and metabarcoding—that infer the species composition of environmental samples from DNA sequences. DNA barcode reference libraries play a critical role in the interpretation of sequences gathered through such protocols, but many lack adequate taxonomic curation, include redundant records, do [...]
A user’s guide for understanding reptile and amphibian hydroregulation and climate change impacts
Published: 2025-04-18
Subjects: Comparative and Evolutionary Physiology, Ecology and Evolutionary Biology, Life Sciences
Human impacts on ecosystems have intensified variation in water variability for terrestrial life, thus challenging the maintenance of water balance, or hydroregulation. The accelerated development and accessibility of technologies and computational models over the past decade have enabled researchers to predict changes in animal hydroregulation and environmental water with greater spatial and [...]

The adaptive maintenance of phenotypic polymorphism
Published: 2025-04-15
Subjects: Life Sciences
Phenotypic polymorphisms have fascinated evolutionary biologists since the field’s inception, providing easily observable and quantifiable variation amenable to both empirical and theoretical study. However, a clear method for developing alternative hypotheses for the adaptive processes by which multiple morphs are maintained remains elusive. Here we review hypotheses for the maintenance of [...]
The Subtlety of Lake Superior Ciscoe Recruitment Dynamics
Published: 2025-04-14
Subjects: Life Sciences
Objective: Lake Superior whitefish [Salmonidae: Coregoninae] have undergone high annual variability in survival to age-1 over the last 50-years, particularly within the dominant ciscoe flock of Bloater Coregonus hoyi, Cisco C. artedi, and Kiyi C. Kiyi. This work sought to determine if this variance was associated with hydrometeorological attributes that have also varied considerably over the same [...]
Delineating freshwater fish biogeographic regions in the Philippine archipelago
Published: 2025-04-14
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
The Philippines, a biodiversity hotspot with a complex geological history, presents an ideal setting to study freshwater fish biogeography in archipelagos. Despite its ecological significance, analyses of freshwater fish distribution patterns across the archipelago remain lacking. This study addresses this knowledge gap by delineating native freshwater fish biogeographic regions in the [...]
