Data for: Thermal tolerance in the urban heat island: Thermal sensitivity varies ontogenetically and differs between embryos of two sympatric ectotherms 

Hall, Joshua M; Warner, Daniel A; http://orcid.org/0000-0002-5587-3402 (2019-09-09)
Most studies of thermal tolerance use adults, but early-life stages (e.g. embryos) are often more sensitive to thermal agitation. Studies that examine effects on embryos rarely assess the potential for thermal tolerance ...

Do Small Classes in Higher Education Reduce Performance Gaps in STEM? 

Ballen, Cissy; Aguillon, Stefanie; Brunelli, Rebecca; Drake, Abby Grace; Wassenberg, Deena; Weiss, Stacey; Zamudio, Kelly; Cotner, Sehoya (2019-07-11)
Performance gaps in science are well documented, and an examination of underlying mechanisms that lead to underperformance and attrition of women and underrepresented minorities (URM) may offer highly targeted means to ...

Free-Boundary Axisymmetric MHD Equilibrium 

Guazzotto, Luca (2018-07-09)
The calculation of equilibrium conditions is a common task in the study and modeling of magnetic-confinement experiments for con- trolled nuclear fusion, in which a high-temperature plasma is confined in a finite region ...

Crossing the Divide: Admixture Across the Antarctic Polar Front Revealed by the Brittle Star Astrotoma agassizii 

Galaska, Matthew P; Sands, Chester J; Santos, Scott R; Mahon, Andrew R; Halanych, Kenneth M (2019-07-31)
The Antarctic Polar Front (APF) is one of the most well-defined and persistent oceanographic features on the planet and serves as a barrier to dispersal between the Southern Ocean and lower latitudes. High levels of endemism ...

Phylogenomic analyses of Crassiclitellata support major Northern and Southern Hemisphere clades and a Pangaean origin for earthworms 

Anderson, Frank E.; Williams, Bronwyn W.; Horn, Kevin M.; Erséus, Christer; Halanych, Kenneth M.; Santos, Scott R.; James, Samuel W. (2019-04-26)
BACKGROUND: Earthworms (Crassiclitellata) are a diverse group of annelids of substantial ecological and economic importance. Earthworms are primarily terrestrial infaunal animals, and as such are probably rather poor natural ...

The players in a mutualistic symbiosis: insects, bacteria, viruses, and virulence genes 

Moran, Nancy A; Degnan, Patrick H; Santos, Scott R; Dunbar, Helen E; Ochman, Howard (2019-08-08)
Aphids maintain mutualistic symbioses involving consortia of coinherited organisms. All possess a primary endosymbiont, Buchnera, which compensates for dietary deficiencies; many also contain secondary symbionts, such as ...

The influence of maternal nesting behaviour on offspring survival: evidence from correlational and cross-fostering studies 

Addis, Elizabeth; Warner, Daniel; Pruett, Jenna (2019-04-22)
The maternal effect of nesting behaviour is important in oviparous species because choice of microhabitat (e.g. shade cover, temperature) can determine the environment in which embryos develop. In turn, this maternal choice ...

Data Supplement for Finding Fault in Dyer County, TN 

Johnson, John (2018-12-13)
Seismic data in SEG-2 format.

Discovery and evolution of novel hemerythrin genes in annelid worms 

Costa-Paiva, Elisa M.; Whelan, Nathan V; Waits, Damien S; Santos, Scott R.; Schrago, Carlos G.; Halanych, Kenneth M. (2019-04-29)
BACKGROUND: Despite extensive study on hemoglobins and hemocyanins, little is known about hemerythrin (Hr) evolutionary history. Four subgroups of Hrs have been documented, including: circulating Hr (cHr), myohemerythrin ...

Longitudinal Analysis of a Diversity Support Program in Biology: A National Call for Further Assessment 

Ballen, Cissy J.; Mason, Nicholas A.; 0000-0002-4693-6117 (2020-05-26)
National calls to improve the performance and persistence of students from historically underrepresented backgrounds in science have led to a surge of research on inclusive, evidence-based teaching methods. Less work has ...

Discovery and broad relevance may be insignificant components of course-based 1 undergraduate research experiences (CUREs) for non-biology majors 

Ballen, Cissy J.; Thompson, Seth K.; Blum, Jessamina E.; Newstrom, Nicholas P.; Sehoya, Cotner; 0000-0002-4693-6117 (2020-05-26)
Course-based undergraduate research experiences (CUREs) are a type of laboratory learning environment associated with a science course in which undergraduates participate in novel research. According to Auchinchloss et ...

Enhancing Diversity in Undergraduate Science: Self-Efficacy Drives Performance Gains with Active Learning 

Ballen, Cissy J.; Wieman, Carl; Salehi, Shima; Searle, Jeremy B.; Zamudio, Kelly R.; 0000-0002-4693-6117 (2019-08-07)
Efforts to retain underrepresented minority (URM) students in science, technology, engineering, and mathematics (STEM) have shown only limited success in higher education, due in part to a persistent achievement gap between ...

Physiological consequences of an altered flow regime on Alabama bass (Micropterus henshalli) 

Earley, Laurie A.; Sammons, Steven M.; Mendonca, Mary T.; Johnston, Carol J.; 0000-0003-0916-9024 (2019-08-06)
There are numerous studies on the effects of dams on aquatic biota, yet relatively little is known about whether hydropeaking activities cause physiological change in fish. Using Alabama bass (Micropterus henshalli) as a ...

nadiv: an R package to create relatedness matrices for estimating non-additive genetic variances in animal models 

Wolak, Mathew E.; 0000-0002-7962-0071 (2019-09-15)
1. The Non-Additive InVerses (nadiv) R software package contains functions to create and use non-additive genetic relationship matrices in the animal model of quantitative genetics. 2. This study discusses the concepts ...

Constantly fluctuating in an inconsistent way: comparing the effects of sinusoidal and naturally fluctuating incubation temperatures on embryo development 

Hall, Joshua M; Warner, Daniel A; http://orcid.org/0000-0002-5587-3402 (2019-09-15)
Temperature is a commonly studied environmental factor influencing embryo development in oviparous ectotherms. Though most studies use constant temperature incubation conditions, researchers are aware of the effects of ...

Thermal Spikes Caused by the Urban Heat Island Effect Result in Differential Egg Survival of a Non-native Lizard (Anolis cristatellus)
