One key evolutionary innovation that separates vertebrates from invertebrates is the notochord, a central element that provides the stiffness needed for powerful movements. Later, the notochord was further stiffened by the vertebrae, cartilaginous …
Ecologists often collect data with the aim of determining which of many variables are associated with a particular cause or consequence. Unsupervised analyses (e.g. principal components analysis, PCA) summarize variation in the data, without regard …
Ecologists often collect multivariate data with the aim of determining which of many possible predictor variables are associated with a response. Unsupervised analyses (e.g. principal components analysis, PCA) find axes that explain variation in …
I woke up this morning to an email saying my first R package, holodeck, was on it’s way to CRAN! It’s a humble package, providing a framework for quickly slapping together test data with different degrees of correlation between variables and differentiation among levels of a categorical variable.
Have you ever pondered whether a muffin is really a breakfast food and not just an excuse to eat cake first thing in the morning? Well, you’ve come to the right blog post!
Plants often experience multiple sources of stress simultaneously, yet little is known about interactive effects of multiple stressors on plant metabolic responses. Plants are well known to respond to both drought and insect herbivory through the …
PLS is a powerful multivariate regression method that has many applications for ecological data. When is it best used, what are its advantages, and how should you report your results?
Poster presentation. Plants often experience multiple sources of stress simultaneously, yet little is known about interactive effects of multiple stressors on plant metabolic responses. Plants are well known to respond to both drought and insect …
Insect attack is usually considered bad for tea yield and quality. However, it is well known that plants produce many secondary metabolites in response to insect attack. Many of these secondary metabolites are important for tea quality, and some …
I know you’re all waiting on the edge of your seats for an update on the cupcakes vs. muffins data science project, but unfortunately I don’t have any answers to that age-old question* yet.
