Reduced plasticity and variance in physiological rates of ectotherm populations under climate change

Daniel W.A. Noble, Fonti Kar, Alex Bush, et al.

Published: 2024-02-17
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences

Climate change is expected to result in warmer and more variable thermal environments globally. Greater thermal variability is expected to result in strong selection pressures leading to genetic adaptation and/or the evolution of adaptive phenotypic plasticity. Such responses depend on genetic and phenotypic variability. However, most work has focused on changes in mean phenotypic responses to [...]

The costs and benefits of publicising species discoveries.

Gerard Ryan, Emily Nicholson, Christopher Baker, et al.

Published: 2024-02-10
Subjects: Applied Mathematics, Biodiversity, Biology

Public information about where species are found can influence what happens to them – from building support to protect their habitat, to telling poachers where to find a target. Recent heated scientific debate about whether to release information about species’ locations when new species or populations are found have highlighted the trade-off between the risk of damage or loss versus the benefits [...]

Sexual system variation in the legumes (Fabaceae): prospects for morphological, evolutionary and genomic study

Quentin Cronk, Leonardo M Borges

Published: 2024-02-01
Subjects: Biology, Botany, Plant Biology, Plant Breeding and Genetics Life Sciences, Plant Sciences

Although the great majority of legume species are cosexual with hemaphrodite flowers, a variety of sexual systems are observed in the family including monoecy, andromonoecy, androdioecy and dioecy. Such broad terms conceal much variation, details that may be of importance in understanding the evolutionary and ecological basis of reproductive systems. This variation is often inadequately described [...]

The genetic basis of a regionally isolated sexual dimorphism involves cortex

Sexual dimorphisms represent a source of phenotypic variation and result from differences in how natural and sexual selection act on males and females within a species. Identifying the genetic basis of dimorphism can be challenging, especially once it is fixed within a species. However, studying polymorphisms, even when fixed within a population, can provide insights into the genetic basis of [...]

Switching to bioplastics may exacerbate ingestion of lost and discarded fishing gear by marine invertebrates

Bioplastics are argued to be more environmentally sustainable than conventional plastics. Yet, little is known about how bioplastics degrade in marine environments or their likelihood of being ingested by animals. We measured changes in the weight of biodegradable, semi-biodegradable, and non-biodegradable fishing gears (soft plastic lures, SPLs) in or out of seawater over 14 days. We then [...]

Inferring the seasonal dynamics and abundance of an invasive species using a spatio-temporal stacked machine learning model

Daniele Da Re, Giovanni Marini, Carmelo Bonannella, et al.

Various modelling techniques are available to understand the temporal and spatial variations of the phenology of species. Scientists often rely on correlative models, which establish a statistical relationship between a response variable (such as species abundance or presence-absence) and a set of predominantly abiotic covariates. The modelling approach choice, i.e. the algorithm, is a crucial [...]

Quantifying clearance rates of restored shellfish reefs using modular baskets

Shellfish reefs are one of the most degraded marine ecosystems, prompting substantial efforts to restore them. While biodiversity gains of restored reefs are well documented, other ecosystem services such as water filtration remain overlooked. We tested whether modular baskets could provide a practical way to measure water filtration by invertebrate communities on restored reefs and assess [...]

Linking biodiversity and nature’s contributions to people (NCP): a macroecological energy flux perspective

Ana Carolina Antunes, Emilio Berti, Ulrich Brose, et al.

Published: 2023-12-08
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences

Linking biodiversity and the provision of nature’s contribution to people (NCP) remains a challenge. This hinders our ability to properly cope with the decline in biodiversity and the provision of NCP under global climate and land use changes. Here, we propose a framework that combines biodiversity models with food web energy flux approaches to evaluate and map NCP at large spatio-temporal [...]

The Palearctic view on a bat fungal disease

Flora Whiting-Fawcett, Anna Sofia Blomberg, Tanya Troitsky, et al.

Published: 2023-12-08
Subjects: Animal Sciences, Biology, Immunology and Infectious Disease, Life Sciences, Zoology

The fungal infection causing white-nose disease in hibernating bats in North America has resulted in dramatic population declines of affected species since it was first discovered in 2007. Shortly after, it was demonstrated that the causative agent, Pseudogymnoascus destructans, is native to the Palearctic, where it also infects several bat species. However, infection in the Palearctic rarely [...]

Towards the next generation of species delimitation methods: an overview of Machine Learning applications

Matheus Salles, Fabricius Domingos

Published: 2023-12-07
Subjects: Biology, Computational Biology, Ecology and Evolutionary Biology, Genetics and Genomics

Species delimitation is the process of distinguishing between populations of the same species and distinct species of a particular group of organisms. Various methods exist for inferring species limits, with most of them being rooted in Coalescent Theory. Their primary goal is to identify independently evolving lineages that should represent separate species. Coalescent models have improved [...]

Functional coherence among miRNA targets: a potential metric for assessing biological signal among target prediction methods in non-model species

Christopher Wheat, Rachel A. Steward, Yu Okamura, et al.

Published: 2023-11-30
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences

Although miRNA regulation of protein production is a likely target of adaptive evolution, high false-positive rates in the identification of mRNAs targeted by miRNAs in non-model species’ complicates interpretation of recent advances. Here we document the challenges and then outline steps for the community to address these challenges.

Whereas vocal sexual dimorphism is widespread amongst birds, it has been historically overlooked in non-passerines such as hummingbirds. By evaluating correlations among sex, behaviors, and vocalizations, the meaning and utility of intentional sound production may be inferred. Anna's Hummingbirds (Calypte anna) exhibit pronounced sexual dimorphism, with males being larger and having more vibrant [...]

Estimating quantitative genetic and phenotypic (co)variances plays a crucial role in investigating key evolutionary ecological phenomena, such as developmental integration, life history tradeoffs, and niche specialization, as well as in describing selection and predicting multivariate evolution in the wild. While most studies assume (co)variances are fixed over short timescales, environmental [...]
