Raspberry Pi: An Update on Sound

Life has been a bit demanding lately, so it has been a while since I last worked on the Raspberry Pis. I had a notion that I might dragoon the Pis into serving as compute engines for a simulation I wrote in Python, and that got me motivated to get new Raspbian images and set […]

Population Modeling in Python

One of the courses I enjoyed most in my Ph.D. program was taught by Prof. Kirk Winemiller on population dynamics. There are various collections of models in various languages out there, and multi-model population dynamic applications. But I still think that there is some utility to rolling my own. Since 2009, I’ve gotten more into […]

Getting to an Inexpensive Audio Datalogger

Well, I spent my Saturday morning programming a C# application for Windows Mobile 5 to periodically record audio. I was aiming to set up a data logger using the Raspberry Pi board I’ve got, but I’ve run into enough problems that I decided to look at another approach. The idea is to log acoustic data […]

Raspberry Pi First Run

I checked the UPS tracking number periodically today. My Raspberry Pi was marked as delivered at about 2:30 today. When I got home, I found the package. I still needed to prepare the SD card, so I brought up the RasPi Wiki instructions for SD card setup and went with the Debian Squeeze distribution to […]

Official Interference in Biology

We’ve heard tales of officialdom greasing the way for people to profit over the consideration of species and ecosystems. Now we’ve got a home-grown Florida tale along those lines. Craig Pittman wrote an article appearing in the Tampa Bay Times that goes into the details. Department of Environmental Protection employee Connie Bersok has been suspended […]

Personal Research and the Budget

Diane and I are working on a personal project to put together an acoustic sampling system that could yield information about the activity levels of snapping shrimp. Whitlow Au and his group have done this sort of thing out in the Pacific. Of course, they’ve gotten research funding to do it. We’re looking to do […]

The Cattleman’s Sage Grouse Rant

An op-ed piece by Mike Deering, the National Cattlemen’s Beef Association Director of Communications, lays out an argument to let ranchers handle conservation of the sage grouse without involving the protection of the Endangered Species Act: The wackos as I still prefer to call them have successfully weaseled their way to the front […]

No One Expects the Comparative Anatomist

Upcoming television series on PBS: Inside Nature’s Giants, begins January 18th at 10 PM. Professor Joy Reidenberg is an unlikely TV star. She’s a comparative anatomist with the Mount Sinai School of Medicine in New York. Physically, she is diminutive, dark-haired and dark-eyed, and not the sort of slender sylph in morphotype that TV producers […]

SMM 2011: Sirenian Workshop

I’m attending the Society for Marine Mammalogy biennial conference this year. The location is the Tampa Convention Center, making this pretty simple to get to. Saturday and Sunday are when various workshops are held. Today, I’m attending the Sirenian workshop. It is an all-day affair, with 33 speakers and over 200 attendees. My early connectivity […]

Not as Simple as They Think

The editors of the Tulsa World think that Lawmakers should adopt stronger wildlife laws. That’s fair enough in light of the tragedy in Ohio where exotic predators like lions, tigers, and bears were released by a suicidal keeper. But the editorial’s structure left much to be desired, in my opinion. They do have a good […]

Multiple Sound Sources in the Bottlenose Dolphin

It’s been a long time coming, but the paper on evidence for multiple sound sources in the bottlenose dolphin appears in the October 15th issue of the Journal of Experimental Marine Biology and Ecology. I’ve been told that the PDF will be freely available soon, hopefully in the next week or so. The abstract is: […]

The Visitor in the Night

About 5 AM, I heard an owl outside the house. I went out to check, since owls and hawks don’t mix well. I wanted to make sure the owl wasn’t near Rusty. The owl turned out to be perched high in an oak tree in the front yard. The owl proved to be a pretty […]

The Unseen Spill

There’s an article in the Austin American Statesman about the ongoing Gulf oil spill. It talks about the effects of the spill throughout the water column. The massive use of dispersants at depth is noted as being experimental: nobody knows exactly what outcomes you get by doing that. Well, other than that less of the […]

Listening to Snapping Shrimp

I’m working on setting up a citizen scientist project to document where snapping shrimp (family Alpheidae) are active pre- and post-contamination by the oil spill in the Gulf of Mexico. In this post, I just want to introduce the basic concepts and provide an example sound file. Snapping shrimp comprise a number of species, mostly […]

“A Special Kind of Air Patrol”

My parents send me interesting articles from my hometown paper, the Lakeland Ledger. One of the latest of these I got was an article by Eric Pera titled, A Special Kind of Air Patrol. It is about Polk county farmers employing American Bird Abatement Service (ABAS) to keep crops like blueberries safe from depredation by […]

State of Zen for Sage Grouse

The Los Angeles Times reports on how the US Interior Department made a decision about sage grouse: The Interior Department declared Friday that an iconic Western bird deserves federal protection under the Endangered Species Act, but declined to offer that protection immediately — a split decision that will allow oil and gas drilling to continue […]

Spoonbill Bowl on March 6th, 2010

The regional National Ocean Sciences Bowl, the Spoonbill Bowl, happens this next Saturday, March 6th, 2010. The location is at the USF Marine Sciences and Fish and Wildlife Institute (100 SE 8th Ave., St. Petersburg, Florida 33701). It gets going pretty early in the morning. This is a quiz competition with each game pitting two […]
