How not to control for multiple testing

While reading the method section of a recent article by Solivares et al, I came upon the following paragraph: "The inclusion of many predictors in statistical models increases the chance of type I error (false positives). To account for this we used a Bernoulli process to detect false discovery rates, where the probability (P) of … Continue reading How not to control for multiple testing

Making a case for hierarchical generalized models

Science is also about convincing others, be it your supervisors or your collaborators, that what you intend to do is relevant to get the answers sought. This “what” can be anything from designing an experiment, to collecting samples or formatting the data. This post was inspired by a recent discussion with one of my supervisor … Continue reading Making a case for hierarchical generalized models

Prediction in ecology -implementing a priority.

In this post I would like to comment a bit on the recent forum paper by Houlahan et al on the importance of prediction to demonstrate ecological understanding. Before going through what I took from the paper I will outline a bit where I stood on prediction and understanding before reading the article. Explanation vs … Continue reading Prediction in ecology -implementing a priority.

Spatial Dynamic in a Host-Parasitoid system

In this post I will explore the spatial dynamic that arise from a simple deterministic host-parasitoid model with migration in a homogeneous environment. If the previous sentence did not drive you away, congrats (!) you are most certainly in a terminal state towards biological nerditude. The idea of this post emerged while reading Chp. 6 … Continue reading Spatial Dynamic in a Host-Parasitoid system

Simulating local community dynamics under ecological drift

In 2001 the book by Stephen Hubbell on the neutral theory of biodiversity was a major shift from classical community ecology. Before this book the niche-assembly framework was dominating the study of community dynamics. Very briefly under this framework local species composition is the result of the resource available at a particular site and species … Continue reading Simulating local community dynamics under ecological drift

Exploring the diversity of Life using Rvest and the Catalog of Life

I am writing the general introduction for my thesis and wanted to have a nice illustration of the diversity of Arthropods compared to other phyla (my work focus on Arthropods so this is a nice motivation). As the literature I have had access so far use pie charts to graphically represent these diversities and knowing … Continue reading Exploring the diversity of Life using Rvest and the Catalog of Life
