Distinct Roles of Tumor Associated Mutations in Collective Cell Migration

Rachel Lee & Stuart Martin
Recent evidence suggests that groups of cells are more likely to form clinically dangerous metastatic tumors, emphasizing the importance of understanding mechanisms underlying collective behavior. The emergent collective behavior of migrating cell sheets in vitro has been shown to be disrupted in tumorigenic cells but the connection between this behavior and in vivo tumorigenicity remains unclear. We use particle image velocimetry to measure a multidimensional migration phenotype for genetically defined human breast epithelial cell lines...

Drivers of soil microbial community assembly during recovery from selective logging and clear cutting

Jie Chen, Robin L. Chazdon, Nathan Swenson, Han Xu & Tushou Luo
Despite important progress in understanding the impacts of forest clearing and logging on aboveground communities, how these disturbances affect soil microbial β-diversity and the ecological processes driving microbial assemblages are poorly understood. Further, whether and how the microbial shifts affect vegetation composition and diversity during recovery of post-logged forests remain elusive. 2. Using a spatial grid experiment design in a primary tropical forest intermixed with post-logged patches naturally recovered for half century in Hainan Island,...

Repeated genetic and adaptive phenotypic divergence across tidal elevation in a foundation plant species

Robyn Zerebecki, Erik E Sotka, Torrance C Hanley, Katherine L. Bell, Catherine Gehring, Chris C. Nice, Christina L. Richards & A Randall Hughes
Microgeographic genetic divergence can create fine-scale trait variation. When such divergence occurs within foundation species, then it might impact community structure and ecosystem function, and cause other cascading ecological effects. We tested for parallel microgeographic trait and genetic divergence in Spartina alterniflora , a foundation species that dominates salt marshes of the US Atlantic and Gulf coasts. Spartina is characterized by tall-form (1-2m) plants at lower tidal elevations and short-form (<0.5m) plants at higher tidal...

Ecological and behavioral mechanisms of density-dependent habitat expansion in a recovering African ungulate population

Justine A. Becker, Matthew Hutchinson, Arjun Potter, Shinkyu Park, Jennifer Guyton, Kyler Abernathy, Victor Americo, Ana Gledis Da Conceiçāo, Tyler Kartzinel, Luca Kuziel, Naomi Leonard, Eli Lorenzi, Nuno Martins, Johan Pansu, William Scott, Maria Stahl, Kai Torrens, Marc Stalmans, Ryan Long & Robert Pringle
Major disturbances can temporarily remove factors that otherwise constrain population abundance and distribution. During such windows of relaxed top-down and/or bottom-up control, ungulate populations can grow rapidly, eventually leading to resource depletion and density-dependent expansion into less-preferred habitats. Although many studies have explored the demographic outcomes and ecological impacts of these processes, fewer have examined the individual-level mechanisms by which they occur. We investigated these mechanisms in Gorongosa National Park, where the Mozambican Civil War...

Experimental evidence for the recovery of mercury-contaminated fish populations

Lee Hrenchuk, Paul Blanchfield, John Rudd, Marc Amyot, Christopher Babiarz, Ken Beaty, Drew Bodaly, Brian Branfireun, Cynthia Gilmour, Jennifer Graydon, Britt Hall, Reed Harris, Andrew Heyes, Holger Hintelmann, James Hurley, Carol Kelly, David Krabbenhoft, Steve Lindberg, Robert Mason, Michael Paterson, Cheryl Podemski, Ken Sandilands, George Southworth, Vincent St. Louis, Lori Tate … & Michael Tate
Anthropogenic releases of mercury (Hg) are a human health issue because the potent toxicant methylmercury (MeHg), formed primarily by microbial methylation of inorganic Hg in aquatic ecosystems, bioaccumulates to high concentrations in fish consumed by humans. Predicting the efficacy of Hg pollution controls on fish MeHg concentrations is complex because many factors influence the production and bioaccumulation of MeHg. Here we conducted a 15-year whole-ecosystem, single-factor experiment to determine the magnitude and timing of reductions...

Data for: Many-body thermodynamics on quantum computers via partition function zeros

Akhil Francis, Daiwei Zhu, Cinthia Huerta Alderete, Sonika Johri, Xiao Xiao, James K. Freericks, Christopher Monroe, Norbert M. Linke & Alexander F. Kemper
Partition functions are ubiquitous in physics: they are important in determining the thermodynamic properties of many-body systems, and in understanding their phase transitions. As shown by Lee and Yang, analytically continuing the partition function to the complex plane allows us to obtain its zeros and thus the entire function. Moreover, the scaling and nature of these zeros can elucidate phase transitions. Here we show how to find partition function zeros on noisy intermediate-scale trapped ion...

Infection data and spore counts for cross inoculation experiments

Emily Bruns, Janis Antonovics & Michael Hood
Determining the processes that drive the evolution of pathogen host range can inform our understanding of disease dynamics and the potential for host-shifts. In natural populations, patterns of host range could be driven by genetically based differences in pathogen infectivity or ecological differences in host availability. In northwestern Italy, four reproductively isolated lineages of the fungal plant-pathogen Microbotryum have been shown to co-occur on several species in the genus Dianthus. We carried out cross-inoculation experiments...

Data for: Successful management of invasive rats across a fragmented landscape

Erin Rankin, Sarah Barney, Devin Leopold, Kainana Francisco, David Flaspohler, Tad Fukami, Christian Giardina, Daniel Gruner, Jessie Knowlton & William Pitt
This dataset is from the manuscript "Successful management of invasive rats across a fragmented landscape" and provides the details on snap trap and tracking card data in a broadscale rat removal effort 2011-2015 in the Upper Waiakea Forest Reserve on the Island of Hawai‘i. It describes the successful trapping efforts as well as long term tracking data, which allow us to describe patterns of habitat use of non-native vertebrate species in these naturally fragmented forests...

Dock‐based and dockless bikesharing systems: analysis of equitable access for disadvantaged communities

Xiaodong Qian, Miguel Jaller, Debbie Niemeier & Miao Hu
Dockless bikeshare systems show potential for replacing traditional dock-based systems, primarily by offering greater flexibility for bike returns. However, many cities in the US currently regulate the maximum number of bikes a dockless system can deploy due to bicycle management issues. Despite inventory management challenges, dockless systems offer two main advantages over dock-based systems: a lower (sometimes zero) membership fee, and being free-range (or, at least free-range within designated service areas). Moreover, these two advantages...

High resource overlap and small dietary differences are widespread in food-limited warbler communities

Cody Kent, Kyu Huh, Sarah Hunter, Kathryn Judson, Luke Powell & Thomas Sherry
Although both interspecific competition and coexistence mechanisms are central to ecological and evolutionary theory, past empirical studies have generally focused on simple (two-species) communities over short time periods. Experimental tests of these species interactions are challenging in complex study systems. Moreover, a number of studies of ‘imperfect generalists’, consistent with Liem’s Paradox, raise questions about the ability of evolved species differences to effectively partition niche space when resources vary considerably across the annual cycle. Here...

Functional biogeography of Neotropical moist forests: trait-climate relationships and assembly patterns of tree communities

Bruno Pinho, Marcelo Tabarelli, Cajo Ter Braak, S. J. Wright, Victor Arroyo-Rodriguez, Maíra Benchimol, Bettina Engelbrecht, Simon Pierce, Peter Hietz, Bráulio Santos, Carlos Peres, Sandra Müller, Ian Wright, Frans Bongers, Madelon Lohbeck, Ülo Niinemets, Martijn Slot, Steven Jansen, Davi Jamelli, Renato Augusto Ferreira De Lima, Nathan Swenson, Richard Condit, Jos Barlow, Ferry Slik, Manuel Hernández-Ruedas … & Felipe Melo
Aim: Here we examine the functional profile of regional tree species pools across the latitudinal distribution of Neotropical moist forests, and test trait-climate relationships among local communities. We expected opportunistic strategies (acquisitive traits, small seeds) to be overrepresented in species pools further from the equator due to long-term instability, but also in terms of abundance in local communities in currently wetter, warmer and more seasonal climates. Location: Neotropics. Time period: Recent. Major taxa studied: Trees....

Temporal and sociocultural effects of human colonisation on native biodiversity: Filtering and rates of adaptation

Christophe Amiot, Christophe Amiot, Weihong Ji, Erle Ellis & Michael Anderson
Modern human societies have negatively impacted native species richness and their adaptive capacity on every continent, in clearly contrasting ways. We propose a general model to explain how the sequence, duration, and type of colonising society alter native species richness patterns through changes in evolutionary pressures. These changes cause different ‘filtering effects’ on native species, while simultaneously altering the capacity of surviving species to adapt to further anthropogenic pressures. This framework may better explain the...

Decline of the brown-throated sloth (Bradypus variegatus Schinz, 1825) in an Atlantic Forest protected area

Gabriel Lopes, Gabriel Penido, Neander Heming & Luisa Diele-Viegas
Estimates on demographic parameters altogether with social factors are integral and can be very useful to assess the risks that a population may face in the future. Rescue operations may provide a unique opportunity to gather data on individuals of an area and thus provide population information. Animal rescue data provided by the Rio de Janeiro Botanical Garden fauna team were used to understand the structure of a population of Bradypus variegatus in an urban...

Do tradeoffs govern plant species responses to different global change treatments?

J. Adam Langley, Emily Grman, Kevin Wilcox, Meghan Avolio, Kimberly Komatsu, Scott Collins, Sally Koerner, Melinda Smith, Andrew Baldwin, William Bowman, Nona Chiariello, Anu Eskelinen, Harry Harmens, Mark Hovenden, Kari Klanderud, Rebecca McCulley, Vladimir Onipchenko, Clare Robinson & Katharine Suding
Plants are subject to tradeoffs among growth strategies such that adaptations for optimal growth in one condition can preclude optimal growth in another. Thus, we hypothesized that the response of plant species abundance to one global change treatment would relate inversely to the response to a second treatment, particularly for treatment combinations that accentuate distinct traits. To address this hypothesis, we examined plant species abundances in 39 global change experiments manipulating CO2, nitrogen, phosphorus, water,...

The probability of being infected with haemosporidian parasites increases with host age

Samuel Slowinski, Aidan Geissler, Nicole Gerlach, Britt Heidinger & Ellen Ketterson
In vertebrates, disease susceptibility often varies with age. Older individuals may be more susceptible than younger individuals due to senescent declines in immune function. Alternatively, disease susceptibility may decrease with age if older individuals are more likely to have had prior exposures to parasites and acquired adaptive immune responses that allowed them to resist future infections. Disease susceptibility can also vary with reproductive state, and reproductive hormones have been shown to increase infection susceptibility. Here...

Resistance correlations influence infection by foreign pathogens

Michael E. Hood, Noah Lerner, Victoria Luizzi, Janis Antonovics & Emily Bruns
Reciprocal selection promotes the specificity of host-pathogen associations and resistance polymorphisms in response to disease. However, plants and animals also vary in response to pathogen species not previously encountered in nature, with potential effects on new disease emergence. Using anther-smut disease, we show that resistance (measured as infection rates) to foreign pathogens can be correlated with standing variation in resistance to an endemic pathogen. In Silene vulgaris, genetic variation in resistance to its endemic anther-smut...
