Inferring diet, disease, and antibiotic resistance from the ancient oral microbiome
Published: 2023-11-17
Subjects: Bacteriology, Computational Biology, Life Sciences
The interaction between a host and its microbiome is an area of intense study. For the human host, it is known that the various body site-associated microbiomes impact heavily on health and disease states. For instance, the oral microbiome is a source of various pathogens and potential antibiotic resistance gene pools. The effect of historical changes to the human host and environment to the [...]
Automated tracking of avian parental care behavior
Published: 2023-11-16
Subjects: Behavior and Ethology, Biology, Life Sciences
1. Parental care may be an important source of phenotypic variation for ecological and evolutionary processes. However, it can be difficult to collect and interpret data on parental care behaviors. To address these challenges, we developed a new hardware and software platform for automated behavioral tracking called ABISSMAL (Automated Behavioral Tracking by Integrating Sensors that Survey [...]
Executive functions and brain morphology of male and female dominant and subordinate cichlid fish
Published: 2023-11-16
Subjects: Life Sciences
Living in a social dominance hierarchy presents different benefits and challenges for dominant and subordinate males and females, which might in turn affect their cognitive needs. Despite the extensive research on social dominance in group-living species, there is still a knowledge gap regarding how social status impacts brain development and cognitive abilities. Here, we tested male and female [...]
ATLANTIC SPATIAL: a dataset of landscape, topographic, hydrological and anthropogenic metrics for the Atlantic Forest
Published: 2023-11-16
Subjects: Spatial Science, Terrestrial and Aquatic Ecology
Space is one of the main drivers of biodiversity, once it regulates the underlying processes affecting the distribution and dynamics of species and communities. It is a fundamental factor in the face of the rapid climate and land use and land cover changes at local and global scales, which are linked to habitat loss and fragmentation and their impacts on various organisms. The Atlantic Forest of [...]
Forecasting insect dynamics in a changing world
Published: 2023-11-16
Subjects: Ecology and Evolutionary Biology, Entomology
Predicting how insects will respond to stressors through time is difficult because of the diversity of insects, environments, and approaches used to monitor and model. Forecasting models take correlative/statistical, mechanistic models, and integrated forms; in some cases, temporal processes can be inferred from spatial models. Because of heterogeneity associated with broad community [...]
Sex-specific overdominance at the maturation vgll3 gene for reproductive fitness in wild Atlantic salmon
Published: 2023-11-15
Subjects: Life Sciences
Linking reproductive fitness with adaptive traits at the genomic level can shed light on the mechanisms that produce and maintain sex-specific selection. Here, we construct a multigenerational pedigree to investigate sex-specific selection on a maturation gene, vgll3, in a wild Atlantic salmon population. The vgll3 locus is responsible for ~40% of the variation in maturation (sea age at first [...]
Isotopic Evidence for Long-term Bioaccumulation of Perfluoroalkyl Substances (PFASs) in Icelandic seabirds
Published: 2023-11-15
Subjects: Life Sciences
Per- and polyfluoroalkyl substances (PFASs) are persistent anthropogenic pollutants with a widespread and significant impact on global marine ecosystems, particularly in the Arctic. Our study is centered in Iceland, an area where the merging of boreal and Arctic marine currents creates a complex ecological landscape. This setting is increasingly being influenced by the warming climate, adding [...]
Polyploid plants take cytonuclear perturbations in stride
Published: 2023-11-13
Subjects: Biology, Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences, Plant Biology
Hybridization in plants is often accompanied by nuclear genome doubling (allopolyploidy), which has been hypothesized to perturb interactions between nuclear and cytoplasmic (mitochondrial and plastid) genomes by creating imbalances in the relative copy number of these genomes and producing genetic incompatibilities between maternally derived cytoplasmic genomes and the half of the allopolyploid [...]
Urban heat stress and perceived health impacts in major cities of Bangladesh
Published: 2023-11-12
Subjects: Environmental Studies, Social and Behavioral Sciences, Urban Studies and Planning
Urban heatwaves are a growing concern, especially in South Asian countries grappling with rapid urbanization and limited resources. While prior studies focused on the biophysical aspects of urban heat islands in this region, there is limited evidence of people’s understanding of urban heat stress and its health consequences. This study aimed to investigate the perceived urban heat risk and [...]
Extra-pair paternity variation in two passerine birds breeding in a gradient of urbanisation
Published: 2023-11-10
Subjects: Life Sciences
Urbanisation has been increasing worldwide in recent decades, driving environmental change and exerting novel selective pressures on wildlife. Phenotypic differences between urban and rural individuals have been widely documented in several taxa. However, the extent to which urbanisation impacts mating strategies is less known. Here, we inferred extra-pair paternity variation in nestbox-breeding [...]
Decomposing social environment effects on eco-evolutionary dynamics: from density regulation to frequency-dependent selection
Published: 2023-11-08
Subjects: Life Sciences, Social and Behavioral Sciences
The density and frequencies of interacting phenotypes create a type of environment which affects both phenotypic selection and population growth. Fluctuations in population density create temporal variation in population mean fitness, driving population dynamics, while fluctuations in phenotypic frequencies create variation in the relative fitness of phenotypes through frequency-dependent [...]
Refining the trophic diversity, ecological network structure, and bottom-up importance of prey groups for temperate reef fishes
Published: 2023-11-07
Subjects: Ecology and Evolutionary Biology, Integrative Biology, Life Sciences, Marine Biology
Marine fish communities are highly diverse, including all trophic levels of consumers and contributing to many ecosystem processes. Understanding the specific functional roles of many fish species and the importance of different prey groups for sustaining fish communities has, however, been limited by the historical classification of fishes into a few coarse trophic guilds. Using detailed diet [...]
The economics of nature’s healing touch: A systematic review and conceptual framework of green space, pharmaceutical prescriptions, and healthcare expenditure associations
Published: 2023-11-07
Subjects: Epidemiology
Green spaces play a crucial role in promoting sustainable and healthy lives. Recent evidence shows that green space also may reduce the need for healthcare, prescription medications, and associated costs. This systematic review provides the first comprehensive assessment of the available literature examining green space exposure and its associations with healthcare prescriptions and expenditures. [...]
Comparative life-history responses of lacewings to changes in temperature
Published: 2023-11-04
Subjects: Life Sciences
Insects play a crucial role in all ecosystems, and are increasingly exposed to higher in temperature extremes under climate change, which can have substantial effects on their abundances. However, the effects of temperature on changes in abundances or population fitness are filtered through differential responses of life-history components, such as survival, reproduction, and development, to [...]
Darwin’s road not taken: white sclera, shared intentionality, niche construction, predator fear, teams and Homo origins
Published: 2023-11-04
Subjects: Behavior and Ethology, Evolution, Neuroscience and Neurobiology
Palaeoanthropologists have yet to pinpoint how Homo evolved from Australopithecus. I propose niche construction ending predator ambush and stalking attacks, white sclera, and ultrafast team cognition were key. Human white sclera allows the quick, distant detection of line-of-sight. This is unique. In other primates, predators eliminate conspicuous-eyed individuals. Consequently, nonhuman [...]
