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 [...]
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 [...]
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 [...]
Sharing the burden: Cabbage stem flea beetle pest pressure and crop damage are lower in rapeseed fields surrounded by other rapeseed crops
Published: 2023-11-04
Subjects: Agriculture, Entomology, Life Sciences, Other Ecology and Evolutionary Biology
The cabbage stem flea beetle (Psylliodes chrysocephala) is a significant pest of rapeseed (Brassica napus). Feeding by adult P. chrysocephala can cause severe leaf damage and larval infestation can reduce stem strength, both of which impact crop growth and development, causing substantial yield losses and economic damage. The structure of the agricultural landscape can regulate herbivorous pest [...]
Signatures of global processes shaping the structure of microbial co-occurrence networks
Published: 2023-11-01
Subjects: Ecology and Evolutionary Biology, Environmental Microbiology and Microbial Ecology Life Sciences, Life Sciences
Co-occurrence networks offer insights into the complexity of microbial interactions, particularly in highly diverse environments where direct observation is challenging. However, identifying the scale at which local and non-local processes structure co-occurrence networks remains challenging because it requires simultaneously analyzing network structure within and between local networks. In this [...]
The behavioural costs of overcrowding for gregarious cave-dwelling bats
Published: 2023-11-01
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
1. Bats are known for their gregarious social behaviour, often congregating in caves and underground habitats, where they play a pivotal role in providing various ecosystem services. Studying bat behaviour remains an underexplored aspect of bat ecology and conservation despite its ecological importance. 2. We explore the costs and impacts of overcrowding on bat social behaviour. This study [...]
Endocrine flexibility can facilitate or constrain the ability to cope with global change.
Published: 2023-10-30
Subjects: Life Sciences
Global climate change has increased average environmental temperatures world-wide, simultaneously intensifying temperature variability and extremes. Growing numbers of studies have documented phenological, behavioral, and morphological responses to climate change in wild populations. As systemic signals, hormones can contribute to orchestrating many of these phenotypic changes. Yet little is [...]
Industrial fishing compliance with a new marine corridor near the Galapagos Islands
Published: 2023-10-30
Subjects: Agricultural and Resource Economics, Aquaculture and Fisheries Life Sciences, Life Sciences, Marine Biology
Examining fishing pressure in under-resourced marine regions still presents a challenge to understanding patterns of fishing pressure. These issues are compounded in areas with complex marine zoning regulations or those that have changed over time. Satellite-based positioning tracking of fishing vessels has helped identify ocean-wide fishing effort distribution and potential encroachments into [...]
The dispersal potential of endangered plants versus non-native garden escapees
Published: 2023-10-30
Subjects: Biodiversity, Life Sciences, Plant Sciences
Amidst global challenges like climate change, plant dispersal corridors are essential. In human-dominated landscapes, urban and rural green spaces are key dispersal avenues. Non-native plants are known to benefit from these, yet the potential benefits for endangered plants remain unclear. To address this question, I compared dispersal traits of endangered native plants with those of [...]
Delivering on a promise: Futureproofing automated insect monitoring methods
Published: 2023-10-26
Subjects: Life Sciences
Due to rapid technological innovations, the automated monitoring of insect assemblages comes within reach. However, this continuous innovation endangers the methodological continuity needed for calculating reliable biodiversity trends in the future. Maintaining methodological continuity over prolonged periods of time is not trivial, since technology improves, reference libraries grow, and both [...]
Global research priorities for historical ecology to inform conservation
Published: 2023-10-26
Subjects: Arts and Humanities, Life Sciences, Social and Behavioral Sciences
Historical ecology draws on a broad range of information sources and methods to provide insight into ecological and social change, especially over the past ~12,000 years. While its results are often relevant to conservation and restoration, insights from its diverse disciplines, environments, and geographies have frequently remained siloed or underrepresented, restricting their full potential.
