Expectation, motivation, engagement and ownership: using student reflections in the conative and affective domains to enhance residential field courses (2019)
Journal Article
Scott, G. W., Humphries, S., & Henri, D. C. (2019). Expectation, motivation, engagement and ownership: using student reflections in the conative and affective domains to enhance residential field courses. Journal of geography in higher education, 43(3), 280-298. https://doi.org/10.1080/03098265.2019.1608516

Residential field courses are important and should be designed and delivered to maximize their value to students, staff and institutions. In this context, we use a novel approach involving analysis of the daily affective and conative reflections of s...

A physical explanation of the temperature dependence of physiological processes mediated by cilia and flagella (2013)
Journal Article
Humphries, S. (2013). A physical explanation of the temperature dependence of physiological processes mediated by cilia and flagella. Proceedings of the National Academy of Sciences of the United States of America, 110(36), 14693-14698. https://doi.org/10.1073/pnas.1300891110

The majority of biological rates are known to exhibit temperature dependence. Here I reveal a direct link between temperature and ecologically relevant rates such as swimming speeds in Archaea, Bacteria, and Eukaryotes as well as fluid-pumping and fi...

Effect of particulate contamination on adhesive ability and repellence in two species of ant (Hymenoptera; Formicidae) (2012)
Journal Article
Anyon, M. J., Orchard, M. J., Buzza, D. M. A., Humphries, S., & Kohonen, M. M. (2012). Effect of particulate contamination on adhesive ability and repellence in two species of ant (Hymenoptera; Formicidae). The journal of experimental biology, 215(4), 605-616. https://doi.org/10.1242/jeb.063578

Tarsal adhesive pads are crucial for the ability of insects to traverse their natural environment. Previous studies have demonstrated that for both hairy and smooth adhesive pads, significant reduction in adhesion can occur because of contamination o...

Comparative analysis of teleost genome sequences reveals an ancient intron size expansion in the zebrafish lineage (2011)
Journal Article
Moss, S. P., Joyce, D. A., Humphries, S., Tindall, K. J., & Lunt, D. H. (2011). Comparative analysis of teleost genome sequences reveals an ancient intron size expansion in the zebrafish lineage. Genome Biology and Evolution, 3(1), 1187-1196. https://doi.org/10.1093/gbe/evr090

We have developed a bioinformatics pipeline for the comparative evolutionary analysis of Ensembl genomes and have used it to analyze the introns of the five available teleost fish genomes. We show our pipeline to be a powerful tool for revealing vari... Read More about Comparative analysis of teleost genome sequences reveals an ancient intron size expansion in the zebrafish lineage.

Positive allometry and the prehistory of sexual selection (2010)
Journal Article
Tomkins, J. L., Lebas, N. R., Witton, M. P., Martill, D. M., & Humphries, S. (2010). Positive allometry and the prehistory of sexual selection. The American naturalist, 176(2), 141-148. https://doi.org/10.1086/653001

The function of the exaggerated structures that adorn many fossil vertebrates remains largely unresolved. One recurrent hypothesis is that these elaborated traits had a role in thermoregulation. This orthodoxy persists despite the observation that tr... Read More about Positive allometry and the prehistory of sexual selection.

Filter feeders and plankton increase particle encounter rates through flow regime control (2009)
Journal Article
Humphries, S. (2009). Filter feeders and plankton increase particle encounter rates through flow regime control. Proceedings of the National Academy of Sciences of the United States of America, 106(19), 7882-7887. https://doi.org/10.1073/pnas.0809063106

Collisions between particles or between particles and other objects are fundamental to many processes that we take for granted. They drive the functioning of aquatic ecosystems, the onset of rain and snow precipitation, and the manufacture of pharmac...

Sperm competition: Linking form to function (2008)
Journal Article
Humphries, S., Evans, J. P., & Simmons, L. W. (2008). Sperm competition: Linking form to function. BMC evolutionary biology, 8(1), Article ARTN 319. https://doi.org/10.1186/1471-2148-8-319

Background. Using information from physics, biomechanics and evolutionary biology, we explore the implications of physical constraints on sperm performance, and review empirical evidence for links between sperm length and sperm competition (where two...
