The BBS was designed to capture avian populations in natural areas, so if the land surrounding a portion of the route was developed, historically the route path was altered and given a new number. The problem is, that new numerical designation was not standardized (though often, it’s 100 + the original route number). In wanting […]

As my several recent posts have mentioned, I’m working with BBS spatial data (i.e. route paths and start points). I wanted to “downscale” by splitting routes into smaller segments and looking at data sub-route level. Specifically, I needed to split routes into fifths. I needed to know what order the segments were in from the […]

When I downloaded the BBS route shape file (apologies for not linking, I’m not sure if it’s publicly available) I had some work to do. I wrote down the steps I used in cleaning up the layer, and then splitting into fifths. One line per route. Great! set aside. (Still a note of caution, some […]

I made a series of posts of how to get BBS data and import it into R, as well as an example of predictor data for a model, and how to get that into R. Here I’ll collect it all into a step-by-step by linking to those posts. How to get BBS data Importing BBS […]

BBS data is essentially aggregated point count data, that in its raw form has a row for each species observed at each route in each year. This means that if a species is not recorded in a  given year, it just doesn’t have a record. I need to add those zeros back in, such that if […]

I have used remote sensing products in my BBS analyses in various capacities, but it all boils down essentially to the same spatial statistics. I wrote a post about how to download and process MODIS VCF images. At the end of that post, you have a folder of TIFF images of your variable of interest at […]

I found this gem while poking around Flood Bay this afternoon! It’s a fortification and a floater agate, which is mostly micro-crystalline quartz. Last weekend, my I taught my boyfriend about agate hunting, and we found a number of them. There’s a corner of this one (left) that’s broken to reveal very fine banding, but […]

I’ve been keeping odd-looking rocks I don’t know what to make of to ID later. This one looks like brecciated jasper(?) that got cemented within quartz. There is some banding around the broken pieces.

Until I figure out how to pin posts in a tag(?) here’s where my posts have gotten us so far with a starter script for BBS data. Start with the data tutorial before getting to this step to download North American BBS data. This script imports your data into R… rm(list = ls()) setwd(“”) library(foreign) […]

My significant other, in getting his M.S. research ready for publication, introduced me to multilevel modeling, and we worked through a reanalysis together. Now, I’m also interested to apply this framework to my 2nd dissertation chapter before publishing, so I can model cohesive community response while still extracting species’ responses. The following code block is copied […]
