Implications of adult sex ratios on natal dispersal in a cooperative breeder
Published: 2023-07-15
Subjects: Life Sciences
In cooperatively breeding species, sexually mature individuals may delay natal dispersal and become subordinates, helping a dominant pair raise offspring. To understand how cooperative breeding evolved, it is important to determine the mechanisms leading to delayed dispersal. Adult sex ratio (ASR) variation may affect dispersal through limiting breeding vacancies available to the more abundant [...]

Building a Portuguese Coalition for Biodiversity Genomics
Published: 2023-07-10
Subjects: Genomics
The diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to the Atlantic archipelagos, has made it an important repository of biodiversity throughout the Pleistocene glacial cycles, leading to a remarkable diversity of species and ecosystems. This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, [...]
Shifts in internal stem damage along a tropical precipitation gradient and implications for forest biomass estimation
Published: 2023-07-10
Subjects: Ecology and Evolutionary Biology, Life Sciences
Woody biomass is a large carbon store in terrestrial ecosystems. In calculating biomass, tree stems are assumed to be solid structures. However, decomposer agents such as microbes and insects target stem heartwood, causing internal wood decay which is poorly quantified. We investigated internal stem damage across five sites in tropical Australia along a precipitation gradient. We estimated the [...]
When to monitor or control; informed invasive species management using a partially observable Markov decision process (POMDP) framework
Published: 2023-07-10
Subjects: Other Ecology and Evolutionary Biology
Resource allocation for invasive species management requires information about the size of the invasive population, which may be expensive and time-consuming to obtain. The trade-off between investment in monitoring and control efforts is a challenging decision problem, and existing mathematical tools are often difficult to interpret, and / or limited to a specific case study. We propose a [...]
Reviewing the role of urbanisation in facilitating the introduction and establishment of Invasive Animal Species
Published: 2023-07-09
Subjects: Life Sciences
While urbanisation is often associated to a loss of biodiversity, non-native invasive animal species are strikingly successful in urban landscapes. As biological invasions are recognised to have detrimental environmental, social and economic impacts, extensive understanding of the interactions between invasive species and the abiotic and biotic environment is necessary for effective prevention [...]
Precipitation predictability drives evolution of drought tolerance in Papaver rhoeas
Published: 2023-07-06
Subjects: Life Sciences
Current climate change leads to an increase in the frequency and intensity of droughts and to a decreased precipitation predictability. The few studies investigating plant evolutionary responses to contrasting predictability regimes showed that intrinsic precipitation predictability shapes plant phenotypic variation, drives evolution of phenotypic plasticity, and can vary in strength and [...]
Habitat suitability maps for Australian flora and fauna under CMIP6 climate scenarios
Published: 2023-07-05
Subjects: Ecology and Evolutionary Biology
Background: Spatial information about the location and suitability of areas for native plant and animal species under different climate futures is an important input to land use and conservation planning and management. Australia, renowned for its abundant species diversity and endemism, often relies on modelled data to assess species distributions due to the country's vast size and the [...]
Regenerating tropical forests are consistently affected by biological invasions across spatial scales
Published: 2023-07-04
Subjects: Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Biological invasions are complex scale-dependent processes. Metacommunity ecology provides the means to understand the effects of invasive non-native species (INNS) because it explicitly considers how local and regional processes interact to drive the three main components of bio-diversity: alpha, beta, and gamma. White-popinac (Leucaena leucocephala (Lam.) de Wit) is a widely distributed INNS in [...]
Computationally reproducing results from meta-analyses in Ecology and Evolutionary Biology using shared code and data
Published: 2023-07-04
Subjects: Ecology and Evolutionary Biology
Many journals in ecology and evolutionary biology encourage or require authors to make their data and code available alongside articles. In this study we investigated how often this data and code could be used together, when both were available, to computationally reproduce results published in articles. We surveyed the data and code sharing practices of 177 meta-analyses published in ecology and [...]
Extinction drives recent thermophilization but does not trigger homogenization in forest understory
Published: 2023-07-04
Subjects: Botany, Forest Sciences, Life Sciences, Terrestrial and Aquatic Ecology
The ongoing climate change is triggering plant community thermophilization. This selection process is ought to shift community composition toward species adapted to warmer climates but may also lead to biotic homogenization. The link between thermophilization and homogenization, and the community dynamics that drive them (colonization and extinction) remain unknow, but is critical for [...]
Measuring historical pollution: natural history collections as tools for public health and environmental justice research
Published: 2023-07-04
Subjects: Biodiversity, Environmental Health Life Sciences, Environmental Monitoring, Environmental Policy, Environmental Public Health, Environmental Studies, Health Policy, Inequality and Stratification, Nature and Society Relations, Public Policy, Urban Studies and Planning
Background: Through the industrial era, environmental pollution has been unevenly distributed in the environment, disproportionately impacting disenfranchised communities. The distribution of pollution is thus a question of environmental justice and public health that requires policy solutions. However, we lack robust quantitative data on pollutants for many locations and time periods because [...]
Prevalence and Potential Evolutionary Significance of Color Mutations in Freshwater Crayfish (Decapoda: Astacidea)
Published: 2023-07-04
Subjects: Life Sciences
Color mutations may lead to the evolution and diversification of color phenotypes in animals. However, much of the research on this topic has been conducted on vertebrates. Here, I compile records of color mutations in freshwater crayfish (Decapoda: Astacidea). I found color mutations to be surprisingly common, with 103 documented occurrences. The overwhelming majority of these mutations resulted [...]
Biogeographical distributions of trickster animals
Published: 2023-07-03
Subjects: Arts and Humanities, Ecology and Evolutionary Biology
Human language encompasses almost endless potential for meaning and folklore can theoretically incorporate themes beyond time and space. However, actual distributions of the themes are not always universal and their constraints remain unclear. Here, we specifically focused on zoological folklore and aimed to reveal what restricts the distribution of trickster animals in folklore. We applied the [...]
Measuring the 3-30-300 Rule to Help Cities Meet Nature Access Thresholds
Published: 2023-07-02
Subjects: Environmental Public Health, Environmental Studies, Epidemiology, Geography, Physical and Environmental Geography, Public Health, Social and Behavioral Sciences
The 3-30-300 rule offers benchmarks for cities to promote equitable nature access. It dictates that individuals should see three trees from their dwelling, have 30% tree canopy in their neighborhood, and live within 300 meters of a high-quality green space. Implementing this demands thorough measurement, monitoring, and evaluation methods. Seven data and processes exist to assess these [...]
