Space-for-time substitutions in climate change ecology and evolution
Published: 2022-11-09
Subjects: Ecology and Evolutionary Biology
In an epoch of rapid environmental change, understanding and predicting how biodiversity will respond to a changing climate is an urgent challenge. Since we seldom have sufficient long-term biological data to use the past to anticipate the future, spatial climate-biotic relationships are often used as a proxy for predicting biotic responses to climate change over time. These ‘space-for-time [...]
Heritability and developmental plasticity of growth in an oviparous lizard
Published: 2022-11-09
Subjects: Ecology and Evolutionary Biology
Selective processes act on phenotypic variation although the evolutionary potential of a trait relies on the underlying heritable variation. Developmental plasticity is an important source of phenotypic variation, but it can also promote changes in genetic variation, yet we have a limited understanding on how they are both impacted. Here, we quantified the influence of developmental temperature [...]
Evolutionary origins of the Mesoamerican-eastern United States floristic disjunction: current status and future prospects
Published: 2022-11-07
Subjects: Biodiversity, Biology, Botany, Ecology and Evolutionary Biology, Evolution, Life Sciences, Plant Sciences
Biogeographic disjunction patterns, where multiple taxonomic groups are shared between isolated geographic areas, represent excellent systems for investigating the historical assembly of modern biotas as well as fundamental biological processes such as speciation, diversification, niche evolution, and evolutionary responses to climate change. Studies on plant genera disjunct across the Northern [...]
The Fieldwork Wellness Framework: A new approach to field research in Ecology
Published: 2022-11-07
Subjects: Biology, Ecology and Evolutionary Biology
Fieldwork is often an important aspect of research in Ecology, Evolution, and Conservation Biology (EECB), but individuals with marginalized identities are likely to experience compromised wellness. The responsibility for structurally changing fieldwork to improve experiences and outcomes falls on the entire EECB community. We propose a Fieldwork Wellness Framework to replace traditional [...]
Iterative species distribution modeling results in the discovery of novel populations of a rare cold desert perennial
Published: 2022-11-02
Subjects: Ecology and Evolutionary Biology, Life Sciences
Niche modeling for rare and range-restricted species can generate inaccurate predictions leading to an overestimation of a species geographic distribution. We used an iterative ensemble modeling approach and model-stratified field surveys to improve niche model formulation and better understand the ecological drivers of Ivesia webberi distribution. I. webberi is a U.S. federally threatened [...]
Temperate-tropical transitions are linked with shifts in the structure of evolutionary integration in Vitaceae leaves
Published: 2022-11-01
Subjects: Ecology and Evolutionary Biology, Life Sciences
Understanding how the intrinsic ability of populations and species to meet shifting selective demands shapes evolutionary patterns over both short and long timescales is a major question in biology. One major axis of evolutionary flexibility can be measured by phenotypic integration and modularity. The strength, scale, and structure of integration may constrain or catalyze evolution in the face [...]
Behavioral plasticity allows ungulates to balance risk and reward following megafire
Published: 2022-10-29
Subjects: Ecology and Evolutionary Biology
Anthropogenic climate and land use change has accelerated the frequency of extreme climatic disturbances such as megafire. These megafires dramatically alter ecosystems and threaten the long-term conservation of economically and ecologically important species, including native ungulates. Recent work suggests that ungulate species may be able to adjust to the immediate effects of megafire by [...]
A globally integrated structure of taxonomy supporting biodiversity science and conservation
Published: 2022-10-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
All aspects of biodiversity research, from taxonomy to conservation, rely on data associated with species names. Effective integration of names across multiple fields is paramount and depends on coordination and organization of taxonomic data. We assess current efforts and find that even key applications for well-studied taxa still lack commonality in taxonomic information required for [...]
Beyond genes-for-behaviour: the potential for genomics to resolve questions in avian brood parasitism
Published: 2022-10-27
Subjects: Ecology and Evolutionary Biology, Genetics and Genomics, Life Sciences
Brood parasite-host interactions are among the most easily observable and amenable natural laboratories of antagonistic coevolution, and as such have intrigued evolutionary biologists for decades. It is therefore surprising they have not been at the forefront of genomic studies on evolutionary adaptation. Here we review state-of-the-art molecular methods in studying avian brood parasitism, a [...]
Deep reticulation: the long legacy of hybridization in vascular plant evolution
Published: 2022-10-26
Subjects: Biodiversity, Botany, Ecology and Evolutionary Biology, Evolution, Life Sciences, Plant Biology, Plant Sciences
Hybridization has long been recognized as a fundamental evolutionary process in plants, but our understanding of its phylogenetic distribution and biological significance across deep evolutionary scales has been largely obscure—until recently. Over the past decade, genomic and phylogenomic datasets have revealed, perhaps not surprisingly, that hybridization, often associated with polyploidy, has [...]
Discovering the rules of plant biogeography using a trait-based approach
Published: 2022-09-30
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Lineage-specific traits determine how plants interact with their surrounding environment. As different species may find similar phenotypic solutions through evolution to tolerate, persist in and invade environments with certain characteristics, some traits may become more common in certain types of habitats. These general patterns of geographical trait distribution point towards the existence of [...]
The March of the Human Footprint
Published: 2022-09-29
Subjects: Arts and Humanities, Ecology and Evolutionary Biology, Environmental Indicators and Impact Assessment, Environmental Monitoring, Environmental Sciences, Geography, Human Geography, Life Sciences, Nature and Society Relations, Other Ecology and Evolutionary Biology, Physical Sciences and Mathematics, Remote Sensing, Social and Behavioral Sciences, Spatial Science, Terrestrial and Aquatic Ecology
Human influence is driving planetary change, often in undesirable and unsustainable ways. Recent advances enabled us to measure changes in humanity’s footprint on Earth annually from 2000 – 2019 with a nine-fold improvement in spatial resolution over previous efforts. We found that earlier studies seriously under-estimated the magnitude, extent, and rate of change in the human footprint. [...]
Invasion dynamics of quagga mussels (Dreissena rostriformis bugensis) within a reservoir and its spatially intermittent watershed: Lake Piru and the Santa Clara River, California, USA
Published: 2022-09-29
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Other Ecology and Evolutionary Biology, Terrestrial and Aquatic Ecology
Since its discovery in Lake Mead in 2007, the invasive quagga mussel (Dreissena rostriformis bugensis) has rapidly spread throughout the lower Colorado River drainage. However, the invasion in California remained confined to the Colorado and water systems throughout southern California that receive water from the Colorado River until December 2013, when quagga mussels were first observed in Lake [...]
Best practices in designing, sequencing and identifying random DNA barcodes
Published: 2022-09-28
Subjects: Bioinformatics, Biotechnology, Cell and Developmental Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Random DNA barcodes are a versatile tool for tracking cell lineages, with applications ranging from development to cancer to evolution. Here we review and critically evaluate barcode designs as well as methods of barcode sequencing and initial processing of barcode data. We first demonstrate how various barcode design decisions affect data quality and propose a new optimal design that balances [...]
Individual-based eco-evolutionary framework: towards unifying ecology and evolution
Published: 2022-09-28
Subjects: Biodiversity, Ecology and Evolutionary Biology, Life Sciences
Evolution is increasingly found to be rapid and entangled with ecological processes in complex eco-evolutionary dynamics, calling for a common conceptual framework. Yet, ecological and evolutionary theory remain largely separated, which constrains the development of integrative research. To overcome this separation, I argue for treating the entangled dynamics as a single eco-evolutionary process [...]
