Life history strategies are decoupled from ecomorphological convergence in two Anolis lizards 

Hall, Joshua; Thawley, Christopher; Stroud, James; 0000-0002-5587-3402; 0000-0002-6040-2613; 0000-0003-0734-6795 (2024-10-03)
Convergence is considered powerful evidence for adaptation to similar natural selection pressures. However, for many ecologically and morphologically convergent species, it remains unclear if convergence extends to ...

Supplementary Tables: Blackfin Sucker Mensural and Locality Data 

Armbruster, Jonathan; 0000-0003-3256-0275 (2024-09-27)
A new genus is being described for the Blackfin Sucker and the mensural data and the locality information used to construct the description is included here. The mensural data includes counts and measurements for specimens ...

Developmental reaction norms vary among families of lizards in response to multivariate nest environments 

Norris, Mike; Daniel, Warner; Hall, Joshua; Norris, M. Christopher; 0000-0002-3102-9151 (2024-08-23)
Developmental plasticity is the capacity of a single genotype to express multiple phenotypes in response to different early-life environments. Such responses are defined by reaction norms, which may vary among individuals ...

Charcoal from bat guano in Cripps Mill Cave 

Tsalickis, Alexandra; Vachula, Richard; Welch, J. Conner; Campbell, Joshua; Waters, Matthew (2024-08-20)
This is charcoal data extracted from a bat guano sediment core that was collected from Cripps Mill Cave in Tennessee, USA

Data for: Estimating the Landscape of Natural Selection During Island Colonization in an Invasive Lizard 

Gilbert, Anthony; Fargevielle, Amélie; Warner, Daniel (2024-05-21)
Colonization of new habitats exposes populations to novel selective pressures, and the evolutionary dynamics of invasive species are determined by how the founding environment interacts with the phenotypes of invaders. ...

Genetic variation underlies plastic responses to global change drivers in the purple sea urchin, Strongylocentrotus purpuratus 

Simon, Olivia M.; Hofmann, Gretchen E.; Wolak, Matthew E.; Strader, Marie E.; 0000-0002-1886-4187; 0000-0002-7962-0071 (2024-05-17)
Phenotypic plasticity and adaptive evolution enable population persistence in response to global change. However, there are few experiments that test how these processes interact within and across generations, especially ...

Stellar Blend Image Classification Using Computationally Efficient Gaussian Processes (MuyGPs) 

Bidese, Rafael; Eleh, Chinedu; Zhang, Yunli; Molinari, Roberto; Billor, Nedret; Priest, Benjamin; Goumiri, Imene; Muyskens, Amanda; Dunton, Alec (2024-04-05)
Stellar blends are a challenge in visualizing celestial bodies and are typically disambiguated through expensive methods. To address this, we propose an automated pipeline to distinguish single stars and blended stars ...

Optimal Upscaling with Transport Maps 

Eleh, Chinedu; van Wyk, Hans-Werner (2024-04-04)
Partial differential equation models often involve space-dependent parameters, such as diffusion coefficients and advection fields, that cannot be measured explicitly and are therefore uncertain. Midpoint (MP), spatial ...

Show Me a Function: More Than Meets the Eye 

Eleh, Chinedu; 0000-0002-4531-5263 (2024-04-04)
Mathematics is a fascinating subject used to understand functions' properties and behavior. From simple precalculus to challenging graduate-level courses, there is an intricate web of functions to explore. Unfortunately, ...

Optimal Parameter Upscaling for Partial Differential Equation Models in Mathematical Biology 

Eleh, Chinedu; van Wyk, Hans-Werner; 0000-0002-4531-5263 (2024-04-04)
Partial differential equation models in mathematical biology often involve space-dependent parameters, such as diffusion coefficients and advection fields, that cannot be measured explicitly and are therefore uncertain. ...

Data for: Multi-delay coherence imaging spectroscopy optimized for ion temperature measurements in the divertor plasma of the Wendelstein 7-X stellarator 

Kriete, David M; Perseo, Valeria; Gradic, Dorothea; Ennis, David A; König, Ralf; Maurer, David A; the W7-X Team; 0000-0002-3657-2911 (2024-03-15)
A new coherence imaging spectroscopy (CIS) diagnostic optimized to measure the C2+ impurity ion temperature Ti spatial distribution in the divertor plasma of the W7-X stellarator is designed, tested, and validated. Using ...

Ar/TTIP dust cloud 

Ramkorun, Bhavesh; 0000-0001-9678-4118 (2024-01-23)

Anemonefish oxygenate their anemone hosts at night 

Szczebak, Joseph T.; Henry, Raymond P.; Al-Horani, Fuad A.; Chadwick, Nanette (2023-09-20)
Many stony coral-dwelling fishes exhibit adaptations to deal with hypoxia among the branches of their hosts; however, no information exists on the respiratory ecophysiology of obligate fish associates of non-coral organisms ...

Net superoxide levels: steeper increase with activity in cooler female and hotter male lizards 

Ballen, Cissy J.; Healey, Mo; Wilson, Mark; Tobler, Michael; Wapstra, Erik; Olsson, Mats (2023-09-20)
Ectotherms increase their body temperature in response to ambient heat, thereby elevating their metabolic rate. An often inferred consequence of this is an overall upregulation of gene expression and energetic expenditure, ...

Can mixed assessment methods make biology classes more equitable 

Sehoya, Cotner; Ballen, Cissy J. (2023-09-20)
Many factors have been proposed to explain the attrition of women in science, technology, engineering and math fields, among them the lower performance of women in introductory courses resulting from deficits in incoming ...

Ion acceleration inside foreshock transients 

Liu, Terry Z.; Lu, San; Angelopoulos, Vassilis; Lin, Yu; Wang, Xueyi; 0000-0003-1778-4289; 0000-0001-5533-5981 (2023-06-17)
Recent observations upstream of Earth's bow shock have revealed that foreshock transients can not only accelerate solar wind ions by reflection at their upstream boundaries but may also accelerate ions inside them. Evidence ...

Magnitude and Predictability of pH Fluctuations Shape Plastic Responses to Ocean Acidification
