Data science is a term that conveniently conveys a collection of methods for dealing with data. However, it is a confusing term in that data science is not necessarily a science—perhaps only rarely so—although it should form a portion of the analytical toolbox of scientists and others that interpret data. As more and more data… Read More What is Data Science?
Geographic projections are mathematical procedures that display the objects on the surface of the earth on a two-dimensional surface. If you imagine trying to cut and flatten out a basketball into a perfectly flat surface you may see why this is not trivial. Geographic projections create two-dimensional maps by tracing vectors from an originating point… Read More Geographical Projections
Creating images of molecules in three dimensions seems at first to be simple enough, but there are some challenges. This is likely why people may either avoid doing so or use a plug-in script for specifically for this. I decided to try my hand at rendering some simplified models of macromolecules. I started with a… Read More Drawing Molecules
I wished to generate a random landscape map of habitat and non-habitat. This will be the arena for the next development in the correlated random walk dispersal model of last month. The landscape generated has large blocks of habitat, i.e., the cell value of habitat or non-habitat is not randomly determined for each cell which… Read More A Simple Random Landscape Generator
Dispersal models are useful in research to examine how changing parameters alter how animals may move. As with other models, they are stripped-down versions of reality in nature that can help us ask better questions, but are not used to test hypotheses. Just for fun, I decided to start a scratch built dispersal model from… Read More A Very Simple Dispersal Model
A bioblitz is a 24-hour survey of the taxa in a defined area. Teams led by experts in different groups of living things survey to find as many different species as possible during that time. These are fun events to take part in. Participants learn of different groups of organisms that are present and different… Read More The Value of a Bioblitz
The mean of eleven o’clock and one o’clock is not six o’clock, so why does your calculator keep telling that it is? Quantities that are cyclical, or circular, in nature need to be approached differently than quantities on a noncyclical scale. These cyclical quantities are commonly encountered in directions (e.g., degrees or radians) and time… Read More Circular Statistics
The question of where to locate field samples is complex. There are many things to consider. This is an important consideration in planning field studies in ecology because this will partly determine the quality of the data and what it can tell you. I will here discuss a few common options for laying out sampling… Read More Field Sampling on a Fibonacci Spiral
Data comes in several forms, and there are things that you can, and can’t, do with different types of data. Even with data in the form of numbers, there are things that can lead to misleading or incorrect results. It is thus important to know first what the question is. Then, think about the analysis… Read More Scales of Numbers
