Using Machine Learning to Link Climate, Phylogeny and Leaf Traits in Eucalypts Through a 50-fold Expansion of Current Leaf Trait Datasets

Karina Guo, William K Cornwell, Jason Grant Bragg

Published: 2023-05-05
Subjects: Life Sciences

Leaf size varies within and between species, and previous work has linked this variation to the environment and evolutionary history separately. However, many previous studies fail to interlink both factors and are often data limited. To address this, our study developed a new workflow using machine learning to automate the extraction of leaf traits (leaf area, largest in-circle area and leaf [...]

Célian Diblasi, Nicola Jane Barson, Marie Saitou

Published: 2023-05-05
Subjects: Life Sciences

Genomic structural variation, genomic rearrangements and karyotype variants are important components on which evolution acts in addition to single nucleotide variants, which are the most common type of variant being studied since the rise of next generation sequencing. These variants have unique mutational mechanisms and evolutionary consequences compared to single nucleotide variants. Here we [...]

Beyond Darwin: General Theory of Evolution of Everything - From the origin of life to the market economy

Erhard Glötzl

Published: 2023-05-05
Subjects: Ecology and Evolutionary Biology, Life Sciences

The basic concern of the general theory of evolution is to understand the entire evolution from the origin of life to the biological, technological, social, and economic structures of the present from a unified point of view and structure. The general theory of evolution can be seen as a comprehensive generalization and extension of Darwin's theory of evolution. It goes far beyond [...]

Subjects: Artificial Intelligence and Robotics, Biodiversity, Environmental Monitoring, Numerical Analysis and Computation, Other Ecology and Evolutionary Biology, Statistical Models, Sustainability

This is a conference paper presented at the ICLR 2023 "Machine Learning for Remote Sensing" workshop. Protecting and restoring ecological connectivity is essential to climate change adaptation, and necessary if species are to shift their geographic distributions to track their suitable climatic conditions over the coming century. Despite the increasing availability of near real-time and high [...]

Building a Queer- and Trans-Inclusive Microbiology Conference

Rachel Gregor, Julie Johnston, Lisa Shu Yang Coe, et al.

Published: 2023-05-03
Subjects: Gender Equity in Education, Microbiology

Microbiology conferences can be powerful places to build collaborations and exchange scientific thought, but for queer and transgender (trans) scientists they can also become sources of alienation and isolation. Many conference organizers would like to create welcoming and inclusive events but feel ill-equipped to make this vision a reality, and a historical lack of representation of queer and [...]

Population decline reduces cooperative breeding in a spatially heterogenous population of superb fairy-wrens

Fiona Backhouse, Helen L. Osmond, Bruce Doran, et al.

Published: 2023-05-03
Subjects: Ecology and Evolutionary Biology, Life Sciences

1. Reproductive performance in birds can be affected by both social environment and small-scale environmental heterogeneity via food abundance, availability of nesting sites, and predation risk. However, to date, the best studies of effects of microhabitat variation on avian populations have been on northern hemisphere passerines using nestboxes, where birds have limited control over nest sites [...]

Acoustic evidence for seasonal resource-tracking migration by a top predator of the deep sea

William K Oestreich, Kelly J Benoit-Bird, Briana Abrahms, et al.

Published: 2023-04-28
Subjects: Life Sciences

The strategies that animals employ to track resources through space and time are central to their ecology and reflect underlying ecosystem phenology. Deep-sea ecosystems represent Earth’s largest habitable space, yet ecosystem phenology and effective animal movement strategies in these systems are unknown. Analyzing seven-plus years of continuous population-level acoustic observations, we find [...]

Morphological and anatomical characterization of extrafloral nectaries of Opuntia streptacantha and Ferocactus recurvus (Cactaceae)

Subjects: Biodiversity, Ecology and Evolutionary Biology

Genetic diversity is a core aspect of biodiversity that has been underrepresented in global conservation policy but is gaining rapidly increasing recognition. Conservation geneticists have traditionally focused on identifying, managing, and safeguarding the adaptive potential of specific populations or species. However, for almost all species, conservation relevant, population-level genetic data [...]

Developing countries such as the Philippines suffer from a lack of policy development and implementation on wastewater treatment and discharge. Chlorella vulgaris is a microscopic green algae that has been employed in other countries for WWT due to its ability to simultaneously reduce pollutants and produce valuable biomass. However, challenges in technology adaptation such as differential [...]

Descriptive inference using large, unrepresentative nonprobability samples: An introduction for ecologists

Rob James Boyd, Gavin Stewart, Oliver Pescott

Published: 2023-04-26
Subjects: Life Sciences

Biodiversity monitoring usually involves drawing inferences about some variable of interest across a defined landscape from observations made at a sample of locations within that landscape. If the variable of interest differs between sampled and non-sampled locations, and no mitigating action is taken, then the sample is unrepresentative and inferences drawn from it will be biased. It is possible [...]

Evidence for ancestral olfactory sensitivity but not discrimination across two living elephant species

Melissa H Schmitt, Matthew S Rudolph, Sarah L Jacobson, et al.

Published: 2023-04-25
Subjects: Social and Behavioral Sciences

While African savanna and Asian elephants split between 4.2-9 MYA, they are often regarded as one united group, ‘elephants,’ even in the scientific literature. This is concerning, as while both are keystone species in their respective habitats, each face different environmental pressures and have rarely been compared experimentally. Savanna elephants must locate resources that vary spatially and [...]

Repeated evolution of extreme locomotor performance independent of changes in extended phenotype use in spiders

Many animals utilize self-built structures – so-called extended phenotypes – to enhance body functions, such as thermoregulation, prey capture or defence. Yet, it is unclear whether the evolution of animal constructions supplements or substitutes body functions. Here, using Austral brown spiders, we explored if the evolutionary loss and gain of silken webs as extended prey capture devices [...]
