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

Anna Elizabeth Nordseth, Jacqueline R Gerson, Lucrecia K Aguilar, et al.

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 [...]

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 [...]

Inferring the identifying features underlying association preferences in wild mixed species parrot groups

Vanessa Ferdinand, Elle Pattenden, Donald Brightsmith, et al.

Published: 2022-09-16
Subjects: Biology, Integrative Biology, Life Sciences

Many animals participate in mixed-species aggregations for a variety of reasons, leading to species specific differences in benefits and costs, resulting in a variety of community assemblage patterns and dynamics based on what information individuals use to make joining decisions. Current research tends to focus specifically on "species" as a defining factor affecting joining decisions. However, [...]

Little transparency and equity in scientific awards for early and mid-career researchers in ecology and evolution

Malgorzata Lagisz, Upama Aich, Bawan Amin, et al.

Published: 2022-09-16
Subjects: Biology, Life Sciences

Scientific awards can shape scientific careers, helping secure jobs and grants. Awards also have a potential to reinforce the “Matthew Effect” and the quest for “novelty” in science when eligibility and assessment criteria give preference to nominees with traditional careers and to “excellent” research. As such, recognition awards for early and mid-career researchers can contribute to the lack of [...]

Publication bias impacts on effect size, statistical power, and magnitude (Type M) and sign (Type S) errors in ecology and evolutionary biology

Yefeng Yang, Alfredo Sánchez-Tójar, Rose E O'Dea, et al.

Subjects: Biology, Ecology and Evolutionary Biology, Environmental Sciences, Life Sciences, Physical Sciences and Mathematics, Statistics and Probability

Collaborative assessments of direct replicability of empirical studies in the medical and social sciences have exposed alarmingly low rates of replicability, a phenomenon dubbed the ‘replication crisis’. Poor replicability has spurred cultural changes targeted at improving reliability in these disciplines. Given the absence of equivalent replication projects in ecology and evolutionary biology, [...]

SpatialBoundaries.jl: Edge detection using spatial wombling

Tanya Strydom, Timothée Poisot

Published: 2022-09-07
Subjects: Biology, Life Sciences

Spatial wombling is an approach for detecting edges within a defined two-dimensional landscape. This is achieved by calculating the rate and direction of change through the interpolation of points. This not only gives an approximation as to the shape of the landscape but can also be used to identify candidate boundaries cells that delimit a shift from one state to another within the landscape. [...]

Does symmetry preclude the evolution of senescence? A comment on Pen & Flatt 2021

Charlotte de Vries, E. Yagmur Erten, Hanna Kokko

Published: 2022-09-07
Subjects: Biology, Life Sciences

Patterns of senescence across the tree of life remain poorly understood and a clearly important task is to identify the minimal conditions for senescence to occur at all. Starting with Weismann in 1882, it has generally been argued that some type of asymmetry between parent and offspring is a prerequisite for old individuals to show declining performance. The intuitive role of asymmetries should, [...]

Unraveling the environment-phenotype-genotype nexus: examples, lessons and prospects from bird plumage colors

Rafael S Marcondes

Published: 2022-09-01
Subjects: Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences

Connecting adaptive phenotypic variation to both its genetic and ecological bases is one of the central goals of evolutionary biology. Birds, due to their ease of study and solid base of existing knowledge, present an ideal clade in which to advance that goal. Bird color traits in particular have a long tradition of being at the forefront of conceptual advances in evolutionary biology. Combined [...]

Decoupled responses of biodiversity facets driven from anuran vulnerability to climate and land use changes

Karoline Ceron, Lilian Sales, Diego José Santana, et al.

Published: 2022-08-30
Subjects: Biology, Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology

Anthropogenic climate and land use changes are the main drivers of biodiversity loss, promoting a major reorganization of the biota in all ecosystems. Biodiversity loss implies not only in the loss of species, but also entails losses in other dimensions of biodiversity, such as functional diversity, phylogenetic diversity and the diversity of ecological interactions.Yet, each of those facets of [...]

The Risk of Avian Influenza in the Southern Ocean: A practical guide

Meagan Leanne Dewar, Michelle Wille, Amandine Gamble, et al.

Published: 2022-08-22
Subjects: Animal Sciences, Biology, Immunology and Infectious Disease, Life Sciences

Advice from Avian Influenza experts suggests that there is a high risk that Highly Pathogenic Avian Influenza will arrive in the Southern Ocean 2022/23-2024/25 austral summers. Since the beginning of 2022, the increasing intensity of highly pathogenic avian influenza (HPAI) H5N1 outbreaks has resulted in the death of hundreds of thousands of seabirds in the Northern Hemisphere, around the [...]

Experimental validation of transposable element insertions using the Polymerase Chain Reaction (PCR)

Miriam Merenciano, Marta Coronado-Zamora, Josefa Gonzalez

Published: 2022-07-30
Subjects: Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences

Transposable elements (TEs), also known as transposons, are repetitive DNA sequences, present in virtually all organisms, that can move from one genomic position to another. TEs can be a source of mutations with important consequences for organisms. Despite their interest, its repetitive nature has made their study very challenging. However, the emergence of new sequencing technologies that allow [...]

European light skin may have evolved as an adaptation to the Neolithic sedentary lifestyle

Manuel Ferrando-Bernal

Published: 2022-07-28
Subjects: Bioinformatics, Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences, Population Biology

Light skin facilitates the penetration of ultraviolet light (UV) radiation through the skin, increasing the synthesis of vitamin D that in turn stimulates bone formation. It has been suggested that light skin appeared in the ancestors of modern Europeans as an adaptation to the conditions of low UV radiation in high latitudes; however, paleogenetic studies have recently shown it did not evolve [...]

Social niche shapes social behavior and cortisol concentrations during adolescence in female guinea pigs

Taylor Lynne Rystrom, S. Helene Richter, Norbert Sachser, et al.

Published: 2022-07-16
Subjects: Behavior and Ethology, Biology, Ecology and Evolutionary Biology, Life Sciences

Individualized social niches arise in social groups and are associated with behavior and hormone (e.g. cortisol) concentrations. During sensitive life phases, social interactions can have a profound impact on the development of social behavior. Focusing on adolescence, we aimed to investigate the relationship between the social niche, social behavior, and cortisol concentrations (baseline and [...]

Pathogen evolution is one of the least predictable components of disease emergence, particularly in nature. Here, building on principles established by the geographic mosaic theory of coevolution, we develop a quantitative, spatially-explicit framework for mapping the evolutionary risk of viral emergence. Driven by interest in diseases like SARS, MERS, and COVID-19, we examine the global [...]
