Second Feast

February 27, 2024
Walking Latigo, Whiskey Bottle, and 118th Street trails today I noticed there was an association between horse manure and rabbit pellets; at eight out of twelve recent piles of horse manure there was a large number of rabbit pellets. Far fewer rabbit pellets were found on trails by themselves, usually less than five in a 3 sq ft area. In contrast, where horse manure was present there are dozens of pellets within one foot of the manure suggesting the bunnies are copr...

"algae is not a plant" it said

I had wander down a basic classifications rabbit hole. Just at the Wikipedia level, so not too deep. Yet. It all started when Gillian had a look over Tumblr and was presented with the provocative claim "algae is not a plant". Um, said I, you don't want to say anything sweeping about "algae". I'm pretty sure some of it is plant, although some of it is not.

The thing is, back in grade school as I grew up in an oceanside town, Ms. Cota was putting together her educational curriculum...

A note on the two Sphingidae "Complex" groups in the United States

This post is meant to store information about the two Sphingidae "Complex" groups in the United States.

  1. Sphinx gordius and Sphinx poecila = Complex Sphinx gordius

You cannot reliably differentiate the adults or larvae of Sphinx gordius and Sphinx poecila morphologically. As of right now, barcoding the COI gene is the best method.

We also are unclear of the range. There are barcoded gordius specimens in Canada and also poecila from as far south as New Je...

Feb 26 - days and numbers

Still thinking about survey and the number of observations to represent species. A different look is to start with individual days and plot number of species against number of observations on those individual days. Using recent years data (2021-2023), for our busier months (Apr-Sep), this is 524 days. There is data for every day for all three year in Jun-Sep, some missing days in Apr-May. Here's the chart:

A change to Alberta fish taxonomy increases our species richness.

Cutthroat trout have been divided into several species with their own subspecies. iNaturalist has now accepted this revision, although FishBase and NatureServe have not. The changes have been accepted by Eschmeyer for well over a year.

In short, Westslope Cutthroat Trout gets elevated to its own species rank, and Yellowstone Cutthroat Trout (an introduced species in Alberta) is a subspecies of Rocky Mountain Cutthroat Trout.

So, in Alberta, we now have:

Fear No Forecast

Winter in Israel brings a different type of cold than in Chicago. It’s a deceivingly mild 40 degrees from November through January, but with such a strong dose of wetness and fog combined with buildings designed to protect against heat, that the indoors feel the same as the outdoors. Fog rolls in each night, and sometimes remains for days at a time. Winds blowing over the hills in a certain way sometimes create a distant howling sound, and in some years (but not this one) it snows. It is...

First county record for Mayapple!

Citizen science at work here! Yesterday I recorded a patch of Mayapple, Podophyllum peltatum. Flower bud not yet open but I hope to see that in a few days. The somewhat umbrella-like leaf structure is distinctive, and varies from having 3 to 9 lobes per leaf. It grows to maybe 1.5’ tall and the entire plant is toxic except for the fruit when ripe yellow. The plant spreads via rhizomes underground and sprouts up individual new plants, which are thus clones, forming a patch of plants, ...

Tracking Townsendia

Townsendia, or Easter daisy, are one of the first plants to bloom in the foothills. Like their common name suggests, you will typically begin seeing them bloom around Easter. Although the weather can be quite cold this time of year, Easter daisy is adapted to withstand freezing conditions and blankets of snow. These plants form low mounds close to the ground, a successful strategy that helps to maximize heat retention during colder periods.

As a member of the Compositae (Asterace...

First Hike-Hopkins State Marine Reserve-Monterey Bay

My first hike was seacliffs in Monterey Bay. The weather was in the 60s and sunny. I started my hike by going towards Hopkins State Marine Reserve and walked the trail alongside it which goes through Andy Jacobson Park (most of my findings were there) and Berwick Park. My goal was to make it to lovers point for some tide pooling, however the tide is only starting to get low and the swell was actually higher than expected. The name of the trail I walked specifically is called the Monterey...
