Evolutionary Game Theory: Simulations

Daniel Friedman & Barry Sinervo
The software examples are all derived in the book by Daniel Friedman and Barry Sinervo, "Evolutionary Games in Natural, Social, and Virtual Worlds", published by Oxford University Press (2016). These Excel simulations, R workspaces, and mathematica programs are designed to illustrate diverse games that can be developed for one-population games such as Hawk Dove, RPS, Defect-Cooperate-TFT, to two population games such as Baseball (pitchers versus batters) or Buyer-Seller. The Excel games D-C-TFT and Baseball are...

Microaggressions Self-Defense: A Workshop for Responding to Microaggressions (Handout)

Christy Byrd
Microaggressions are subtle verbal and non-verbal slights based on group membership, and they are ubiquitous in the lives of racial minorities, women, and LGBTQ individuals (Sue 2010). This is a handout accompanying a paper introducing a role-playing based exercise on effective responses to microaggressions. The workshop draws on the two previous prejudice responding workshops of Plous (2000) and Lawson et al. (2010) but integrates research-based strategies.

Data for Drought-Net rainfall shelters did not cause non-drought effects on photosynthesis for California central coast plants.

Michael Loik
Rainfall interception shelters are frequently used to study the ecological consequences of drought. One common shelter design employs V-shaped plastic troughs spaced on a supporting frame to intercept rainfall. Shading, reflection, and infrared radiation may alter the radiative environment under shelters in ways independent of their intended effect on soil moisture. We measured microclimate and several photosynthetic variables for watered potted plants under rain-out shelters and in open-air, unsheltered plots. We tested whether the shelter...

Utilizing field collected insects for next generation sequencing: effects of sampling, storage, and DNA extraction methods

Kimberly Ballare, Nathaniel Pope, Antonio Castilla, Sarah Cusser, Richard Metz & Shalene Jha
DNA sequencing technologies continue to advance the biological sciences, expanding opportunities for genomic studies of non-model organisms for basic and applied questions. Despite these opportunities, many next-generation sequencing protocols have been developed assuming a substantial quantity of high molecular weight DNA (>100 ng), which can be difficult to obtain for many study systems. In particular, the ability to sequence field-collected specimens that exhibit varying levels of DNA degradation remains largely unexplored. In this study we...

Heat flux and temperature at depth beneath InSight landing site through time

Szilard Gyalay, Francis Nimmo, Ana-Catalina Plesa & Mark Wieczorek
The heat flux and thus temperature gradient of the Martian crust is critical for comparison with measurements of crustal properties. This allows for constraints upon the inferred thermal history of Mars. Each file contains the heat flux and temperature at several depths as a function of time after Mars formed, but assuming different crustal properties.

Gardener demographics, experience, and motivations drive differences in plant species richness and composition in urban gardens

Stacy Philpott, Monika Egerer, Peter Bichier, Hamutahl Cohen, Roseann Cohen, Heidi Liere, Shalene Jha & Brenda Lin
Urban agriculture has received considerable attention for its role in supporting biodiversity and ecosystem services, and health and well-being for growing urban populations. Urban gardens managed with agroecological practices and higher plant diversity support more biodiversity and may support higher crop production. Plant selection in gardens is a function of temperature and environmental conditions and also depends on gardener socio-demographic characteristics, motivations for gardening, and gardening experience. In this study, we examined how plant richness...

Data from: Global hotspots for coastal ecosystem-based adaptation

Holly P. Jones, Barry A. Nickel, Tanja Srebotnjak, Will Turner, Mariano Gonzalez-Roglich, Erika Zavaleta & David G. Hole
Helping the world’s coastal communities adapt to climate change impacts requires evaluating the vulnerability of coastal communities and assessing adaptation options. This includes understanding the potential for ‘natural’ infrastructure (ecosystems and the biodiversity that underpins them) to reduce communities’ vulnerability, alongside more traditional ‘hard’ infrastructure approaches. Here we present a spatially explicit global evaluation of the vulnerability of coastal-dwelling human populations to key climate change exposures and explore the potential for coastal ecosystems to help...

CT DICOM studies from: In vivo measurements of lung volumes in ringed seals: insights from biomedical imaging

Holly Hermann-Sorensen, Nicole Thometz, Kathleen Woodie, Sophie Dennison-Gibby & Colleen Reichmuth
This dataset supports: Hermann-Sorensen, H., Thometz, N.M., Woodie, K., Dennison-Gibby, S., and Reichmuth, C. In vivo measurements of lung volumes in ringed seals: insights from biomedical imaging. Journal of Experimental Biology. Marine mammals rely on oxygen stored in blood, muscle, and lungs to support breath-hold diving and foraging at sea. Here, we used biomedical imaging to examine lung oxygen stores and other key respiratory parameters in living ringed seals (Pusa hispida). Three-dimensional models created from...

Data from: Landscape Context Mediates Avian Habitat Choice in Tropical Forest Restoration

J. Leighton Reid, Chase D. Mendenhall, J. Abel Rosales, Rakan A. Zahawi & Karen D. Holl
Birds both promote and prosper from forest restoration. The ecosystem functions birds perform can increase the pace of forest regeneration and, correspondingly, increase the available habitat for birds and other forest-dependent species. The aim of this study was to learn how tropical forest restoration treatments interact with landscape tree cover to affect the structure and composition of a diverse bird assemblage. We sampled bird communities over two years in 13 restoration sites and two old-growth...

Data from: Testing applied nucleation as a strategy to facilitate tropical forest recovery

Rakan A. Zahawi, Karen D. Holl, Rebecca J. Cole & J. Leighton Reid
Active forest restoration typically involves planting trees over large areas; this practice is costly, however, and establishing homogeneous plantations may favour the recruitment of a particular suite of species and strongly influence the successional trajectory. An alternative approach is to plant nuclei (islands) of trees to simulate the nucleation model of succession and accelerate natural recovery. We evaluated natural tree recruitment over 4 years in a restoration study replicated at eight former pasture sites in...

Surrounding forest cover dataset 2005

David Morales, R. J. Cole, Karen D. Holl & R. A. Zahawi
Forest cover within 100 and 500 m radii from the center of each experimental plot was hand digitized from ortho-rectified 2005 aerial photographs and comprehensively ground checked. Forest cover spans a range from <1% to 66% within a 100-m radius surrounding the plots and from 9% to 89% in a 500-m radius.

Fishing and habitat condition differentially affect size spectra slopes of coral reef fishes

Paul Carvalho, Fakhrizal Setiawan, Karizma Fahlevy, Beginer Subhan, Hawis Madduppa, Guangyu Zhu & Austin Humphries
Marine food webs are structured through a combination of top-down and bottom-up processes. In coral reef ecosystems, fish size is related to life-history characteristics and size-based indicators can represent the distribution and flow of energy through the food web. Thus, size spectra can be a useful tool for investigating the impacts of both fishing and habitat condition on the health and productivity of coral reef fisheries. In addition, coral reef fisheries are often data-limited and...
