House Sparrows as Sentinels of Childhood Lead Exposure

Max M Gillings, Riccardo Ton, Tiarne Harris, et al.

Published: 2024-01-04
Subjects: Environmental Health and Protection, Environmental Monitoring, Environmental Sciences, Physical Sciences and Mathematics

Our understanding of connections between human and animal health has advanced substantially since the canary was introduced as a sentinel of toxic conditions in coal mines. Nonetheless, the development of wildlife sentinels for monitoring human exposure to toxins has been limited. Here, we capitalized on a three-decade long child blood lead monitoring program to demonstrate that the globally [...]

The meaning and measure of concordance factors in phylogenomics

Rob Lanfear, Matthew Hahn

Published: 2024-01-03
Subjects: Evolution

As phylogenomic datasets have grown in size, researchers have developed new ways to measure biological variation and to assess statistical support. Larger datasets have many more sites and many more loci, and therefore less sampling variance. While this means that we can more accurately measure the mean signal in these datasets. the lower sampling variance is often reflected in widely used [...]

Quantifying heritability of the environment using animal models: a case study

Gabriel Munar-Delgado, Marion Nicolaus, Christiaan Both, et al.

Published: 2024-01-03
Subjects: Ecology and Evolutionary Biology

Evolutionary ecology has traditionally studied how natural selection shapes the phenotypes of individuals in response to their environment, which increases population fitness. It is also well known how habitat choice can affect individual local adaptation. However, recent work has highlighted the incompleteness of the link between habitat choice and its evolutionary consequences. By treating the [...]

Experimental rapid and small-scale ecological population divergence in the absence of current natural selection

Gabriel Munar-Delgado, Paula Hidalgo-Rodríguez, Gregorio Sánchez-Montes, et al.

Published: 2024-01-02
Subjects: Life Sciences

Adaptive divergence has long been a core topic in the field of evolutionary biology, with natural selection traditionally considered its only driver. Here we focus on the ability of matching habitat choice to generate population divergence and reproductive isolation. This alternative mechanism of divergence considers that individuals choose their habitats based on an evaluation of the ecological [...]

Performance-dependent movement: An alternative driver of adaptive divergence

Gabriel Munar-Delgado, Francisco Pulido, Pim Edelaar

Published: 2024-01-02
Subjects: Life Sciences

It is a tenet of evolutionary biology that local adaptation is driven by natural selection, while it is hindered by gene flow. This is because random movements between populations disrupt the match between phenotype and the local environment. However, if individuals moved to the environments where they have higher ecological performance, movements between populations could facilitate local [...]

The Role of Pollination Services in Seed Production: A review

Falk Krumbe, Simone Melder, Arndt Feuerbacher

Published: 2023-12-28
Subjects: Life Sciences

In the face of declining insect biodiversity, this study reviews the critical role of pollination services in seed production of food crops. Insects, as pollinators, play a fundamental role in the reproductive processes of both wild and domesticated plants, impacting global agriculture. While previous reviews have assessed the influence of pollinators on primary food production, this review [...]

Using multiple datasets to account for misalignment between statistical and biological populations for abundance estimation

Michelle L Kissling, Paul Lukacs, Kelly Nesvacil, et al.

Published: 2023-12-28
Subjects: Life Sciences

A fundamental aspect of ecology is identifying and characterizing population processes. Because a complete census is rare, we almost always use sampling to make inference about the biological population, and the part of the population at risk of sampling is referred to as the statistical population. Ideally, the statistical population is the same as, or accurately represents its corresponding [...]

Biogeographical diet variation within and between the rabbitfishes Siganus corallinus, Siganus virgatus, Siganus doliatus and Siganus trispilos

Salvador Zarco-Perello, Andrew Hoey, Storm Martin

Published: 2023-12-27
Subjects: Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology

Feeding habits of herbivorous fish play an important role in the form and function of coastal marine ecosystems. Rabbitfishes (Siganidae) have been recognized as important consumers of macroalgae in the coral reefs of the Indo-Pacific region. However, it is unclear how their diet varies among and within species at biogeographical scales. The present study assessed the inter- and intra-specific [...]

Closing Farmland Biodiversity Knowledge Gaps with Digital Agriculture

Ruben Remelgado, Vítězslav Moudrý, Elisa Padulosi, et al.

Published: 2023-12-23
Subjects: Agriculture, Biodiversity

Digital agriculture and biodiversity monitoring share many data collection technologies and analytical methods, yet remain siloed. We propose a pathway to harness Digital Agriculture data streams for dynamic, near-real-time assessments of biodiversity-yield interactions aligned with policy-relevant indicators. Bridging these fields, enabled by advances in science and policy, can enhance farmland [...]

Untangling the complex food webs of tropical rainforest streams

Victor Satoru Saito, Pavel Kratina, Gedimar Barbosa, et al.

Published: 2023-12-23
Subjects: Ecology and Evolutionary Biology, Life Sciences

1- Food webs depict the tangled web of trophic interactions associated with the functioning of an ecosystem. Understanding the mechanisms providing stability to these food webs is therefore vital for conservation efforts and management of natural systems.2- Here, we first characterised a tropical stream meta food web and five individual food webs using a Bayesian Hierarchical approach unifying [...]

Bird life history traits influence the diversity of their associated microbiomes

Corey T Callaghan, Stephanie D Jurburg

Published: 2023-12-23
Subjects: Life Sciences

Background: The avian microbiome plays an essential role in host development, health, and behavior, but while microbiomes of captive birds have been extensively studied, little is known about how life history traits influence the resident microbial diversity of individuals and of species in wild birds. Host traits may shape their associated microbiomes by modulating the exposure of the host to [...]

European native oyster reef ecosystems are universally Collapsed

Philine SE zu Ermgassen, Hannah McCormick, Alison Debney, et al.

Published: 2023-12-23
Subjects: Life Sciences

Oyster reefs are often referred to as the temperate functional equivalent of coral reefs. Yet evidence for this analogy is lacking for the European native species Ostrea edulis and its biogenic habitat. Recently assembled historical data provide a unique opportunity to develop a robust definition for this ecosystem type, confirm that O. edulis are biogenic reef builders, and assess its current [...]

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.

Published: 2023-12-22
Subjects: Biology, Entomology, Life Sciences, Population Biology, Public Health, Virus Diseases

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 [...]

VectAbundance: a spatio-temporal database of vector observations

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

Published: 2023-12-22
Subjects: Entomology, Environmental Public Health, Epidemiology, Life Sciences, Zoology

Modelling approaches play a crucial role in supporting local public health agencies by estimating and forecasting vector abundance and seasonality. However, the reliability of these models is contingent on the availability of standardized, high-quality data. Addressing this need, our study focuses on collecting and harmonizing egg count observations of Aedes albopictus, obtained through ovitraps [...]

Child and Adolescent Foraging: New Directions in Evolutionary Research

Ilaria Pretelli, Alyssa Crittenden, Edmond Dounias, et al.

Published: 2023-12-21
Subjects: Social and Behavioral Sciences

Young children and adolescents in subsistence societies forage for a wide range of resources. They often target child-specific foods, they can be very successful foragers, and they share their produce widely within and outside of their nuclear family. At the same time, while foraging they face risky situations and are exposed to diseases that can influence their immune development. However, [...]
