MCP, KDE, and LoCoH

Three of the most popular methods of home range estimation right now are the minimum convex polygon (MCP), kernel density estimation (KDE), and local convex hull (LoCoH). While there are a multitude more methods out there, e.g. brownian bridges and permissible home range estimation, these are the three methods I’m most familiar with. All examples […]

Local convex hull or LoCoH in R

The local convex hull method of home range estimation is a relatively recent technique. It was developed in 2004 by Getz and Wilmers. You can read the paper here and the follow up 2007 paper here. The strength of the local convex hull method, or LoCoH for short, is that it takes into account the topography of […]

Look at the Kitties

They’re hidden very well. I heard them before I saw them. A hiss and a low growl. I was privileged to be a part of the team that collared puma kittens. This particular litter had three kittens. Paul, our experienced Field Biologist, retrieved the first two kittens, and instructed Anna, the newest grad student, on […]

Packard Scholar

*PLEASE NOTE, the UCSC Packard Scholar is not the same thing as the Packard Fellowship for Science and Engineering. During the summer of 2016, I was privileged to be a Packard Scholar. The Packard Scholarship is an undergraduate research fellowship funded by a gift from the Packard Foundation to encourage undergraduate research. It is administered […]

Reflecting on Pumas

Its been a great year. Never in my wildest dreams did I imagine I would be able to approach pumas, either adults or kittens. Yet, here I am, made all the richer for having done so. I’ve also picked up numerous skills along the way. I’ve worked on radio telemetry and puma captures. There was […]
