Published: 2022-07-01
Subjects: Biodiversity, Bioinformatics, Biology, Biotechnology, Cell and Developmental Biology, Ecology and Evolutionary Biology, Immunology and Infectious Disease, Life Sciences, Other Ecology and Evolutionary Biology, Other Life Sciences
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 [...]
PHENOTYPIC PLASTICITY MADE SIMPLE, BUT NOT TOO SIMPLE
Published: 2022-06-29
Subjects: Biology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Phenotypic plasticity refers to environment-dependent trait expression (Dewitt and Scheiner, 2004). Knowledge of phenotypic plasticity is important in virtually all areas of basic and applied biology. Researchers in applied fields (such as agriculture, medicine, public health, wildlife management, and conservation biology) have a vested interest in knowing how traits are or will be expressed [...]
Ecological networks of an Antarctic ecosystem: a full description of non-trophic interactions
Published: 2022-06-29
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Interactions between organisms are very diverse and attend to multiple biological demands, hence understanding ecological communities requires considering different types of species interactions beyond predation. In this work, we assemble for the first time the non-trophic networks of an Antarctic ecosystem. We report mutualistic (+/+), competitive (-/-), commensalistic (+/0) and amensalistic [...]
Record of Halmahera Walking (Hemiscyllium halmahera) Shark in South Morotai
Published: 2022-06-28
Subjects: Animal Sciences, Life Sciences, Marine Biology, Zoology
Halmahera walking shark (Hemiscyllium halmahera) was first discovered by Allen in 2013 and studies regarding this species are still limited. This species distribution includes Halmahera Island and surrounding islands in North Maluku, such as Ternate, Tidore, Bacan and Morotai. Records in Morotai, one of Indonesias most well-known marine tourism sites for shark diving, are discussed in this study, [...]
The community-function landscape of microbial consortia
Published: 2022-06-28
Subjects: Ecology and Evolutionary Biology, Life Sciences, Population Biology
Quantitatively and predictively linking the composition and function of microbial communities is a major aspiration of microbial ecology. It is also a critical step in the path toward engineering synthetic consortia and manipulating natural microbiomes. The functions of microbial communities are collective properties that emerge from a complex web of molecular interactions between individual [...]
A simple conceptual framework and nomenclature for studying repeated, parallel and convergent evolution
Published: 2022-06-28
Subjects: Ecology and Evolutionary Biology, Evolution, Life Sciences
Parallel and convergent evolution are textbook examples of the role of natural selection in evolution. However, these terms are used interchangeably, and sometimes with conflicting meanings. This has resulted in confusion, which hampers the understanding of the processes underlying these important forms of evolution. In this synthesis, I discuss the issues with current definitions of parallel, [...]
Reimagining the broader impacts criterion in the NSF graduate research fellowship
Published: 2022-06-24
Subjects: Life Sciences
For graduate students, securing prestigious fellowships provides incredible benefits such as increased job opportunities and likelihood of receiving awards. These benefits can be particularly life-changing for a graduate student who may come from a marginalized background. However, the inequity in fellowship distribution hinders the success of graduate students, especially those who are [...]
Dispersal and space use of captive-reared and wild-rehabilitated Harpy Eagles released in Central American landscapes: Implications for reintroduction and reinforcement management
Published: 2022-06-23
Subjects: Ecology and Evolutionary Biology, Life Sciences, Terrestrial and Aquatic Ecology
Understanding the spatial context of animal movements is fundamental for establishment and management of protected areas (PA). However, these data are not readily available for large raptors, particularly for tropical species. We telemetry-tracked 36 captive-reared and wild-rehabilitated Harpia harpyja and estimated dispersal and space use after release in Mesoamerica. We evaluated the [...]
Sea turtle conservation as a blueprint for freshwater turtles in the eastern U.S.
Published: 2022-06-23
Subjects: Education, Law, Life Sciences, Other Life Sciences
With turtles and tortoises being one of the most threatened taxa on the planet, dire conservation action is needed. As a global hotspot for turtles — with over 85 species and subspecies — the U.S. can play a major role in curbing turtle extinction. It has already done so for its six species of sea turtles, which experienced dramatic declines over the 19th and 20th centuries due to human [...]
An operational workflow for producing periodic estimates of species occupancy at large scales
Published: 2022-06-23
Subjects: Biodiversity, Bioinformatics, Ecology and Evolutionary Biology, Life Sciences
Policy makers require high-level summaries of biodiversity change. However, deriving such summaries from raw biodiversity data is a complex process involving several intermediary stages. In this paper, we describe a workflow for generating annual estimates of species’ occupancy at national scales from raw species occurrence data, which can be used to construct a range of policy-relevant [...]
The effect of experimental hybridization on cognition and brain anatomy: limited phenotypic variation and transgression in Poeciliidae
Published: 2022-06-23
Subjects: Behavior and Ethology, Ecology and Evolutionary Biology, Evolution, Life Sciences
Hybridization can promote phenotypic variation and often produces trait combinations distinct from the parental species. This increase in available variation can lead to the manifestation of functional novelty when new phenotypes bear adaptive value under the environmental conditions in which they occur. While the role of hybridization as a driver of variation and novelty in traits linked to [...]
Psychological and Cultural Factors Influencing Antibiotic Prescription

Subjects: Bacteriology, Child Psychology, Health Psychology, Life Sciences, Medicine and Health, Medicine and Health Sciences, Microbiology, Psychiatry and Psychology, Psychological Phenomena and Processes, Psychology, Social and Behavioral Sciences, Sociology, Sociology of Religion
Humans have been giving a selective advantage to antibiotic-resistant bacteria worldwide by inundating the environment with antimicrobials for about one century. As a result, the efficacy of antibiotics has been impaired. Antibiotic resistance is a public health problem, responsible for increases in mortality and extended stays at hospitals. Hospitals and other clinical settings have implemented [...]
Scaling up and down: movement ecology for microorganisms
Published: 2022-06-19
Subjects: Ecology and Evolutionary Biology, Life Sciences, Microbiology
Movement is critical for the fitness of organisms, both large and small. It dictates how individuals acquire resources, evade predators, exchange genetic material, and respond to stressful environments. Movement also influences ecological and evolutionary dynamics at scales beyond the individual organism. However, the links between individual motility and the processes that generate and maintain [...]
The dark web trades wildlife, but mostly for use as drugs
Published: 2022-06-16
Subjects: Biodiversity, Life Sciences
Contemporary wildlife trade is massively facilitated by the Internet. By design, the dark web is one layer of the Internet that is difficult to monitor and lacks thorough investigation. Here, we accessed a comprehensive database of dark web marketplaces to search across c. 2 million dark web advertisements over 5 years using c. 7k wildlife trade-related search terms. We found 153 species traded [...]
