Just a few Galapagos photographs pulled from my Instagram feed. Click or mouse-over to read captions, and email me if you have any burning questions. I only had a few seconds to take many of these shots because the tour I was on was the regular “forced march” variety, and you’re required to stay in sight of the guide. Would love to go back for a more leisurely visit, ideally with a guide who has impaired mobility and walks slowly. I’ll be posting more pictures in the coming weeks, so follow me on Instagram if you’re a Galapagos fan.

Some photographs I took during a visit to La Selva Research Station in 2008. Old, but recently discovered they hadn’t transferred to my site when I bailed on Flickr.
I was stuck inside a small room for most of stay (I was consulting for Organization for Tropical Studies), unfortunately, so not as many pics as I’d like. The full album (approximately 50 images) is below. I wish OTS would hire me again.
This little spider is a golden orb weaver (Nephila clavipes), I think:

For science fans near Philadelphia, here are photographs from a recent visit to the Delaware County Institute of Science, based in Media, Pennsylvania. First my favorite (a grumpy dried frog), then small thumbnails of the rest. Mouse-over a photo to see a brief description of what it is (but try to guess, first), or click it to launch larger version with titles. If you want to see any of the photographs even larger, or want to read the gruesome details, visit my original gallery.
If you are in Media to eat (and you should … see http://www.mediarestaurants.com for listing) or in court because you’re a bad person and got caught (it’s the County seat), you can visit DCIS on a Monday, Thursday, or Saturday morning (9am – 12pm). They also feature monthly talks: the next one is November 9th and focuses on the Mason-Dixon line (oh, yes, there’s a story there).

[PUBLIC SERVICE ANNOUNCEMENT] Last week, I witnessed a visually impaired man with a cane walk right into some overgrown hedges while he was heading into town. Clearly surprised, he decided to cross the street before continuing on his way. So I thought I’d post a plea for all of us who have sidewalks to please hack back any creeping shrubs, hostas, and dandelions so that our public walkways are fully walkable by all — not just for the visually impaired, but also for those with twin babies in double strollers, and for couples who just want to hold hands while walking next to each other. Currently, double-wide strollers and hand-holders need to walk in the street, which is crazy given that our town has fairly wide sidewalks. A further benefit of keeping your plants out of the sidewalk airspace is that the foliage doesn’t provide the perfect lurking spot for deer ticks, questing for a host with their hungry little arthropod arms. Yea, that last reason is far-fetched, perhaps, but we have lots of deer and mice and dogs, so it’s just something to think about as you brush by the leaves.

Photographs from some local serpentine barrens — areas that are naturally toxic due to the magnesium, cobalt, nickel, chromium, asbestos, other nasties leaching out from the green serpentine rocks (California’s state rock). Serpentine soil is also famously low in phosphorous and potassium, so not many plants can grow on it. Here’s a typical patch of rock (from Nottingham pine barrens in Pennsylvania):
Below is a close-up of the rocks themselves. I liked the central rock because of its serpentine (wavy, snakelike) marbling. From Pink Hill barrens at the Tyler Arboretum in Media, Pennsylvania.
Here’s a view of a serpentine barrens at Nottingham barrens. If you were to take a close look at these pines, a lot of them have scorched bark from a recent prescribed burn that was conducted to restore native plants to the area.
The flower below is moss phlox (Phlox subulata) at Pink Hill. The plant is absolutely adorable. I’m a sucker for any plant that assumes a moss-like habit.
Below is a close-up of some sort of sedge, possibly Pennsylvania sedge (Carex pensylvanica), but I didn’t have any fruit so I can’t be sure (tentative ID courtesy Dr Roger Latham of Dr Roger Latham at Continental Conservation). But I’m positive it’s adorable, though not mossy in habit. Photograph also from Pink Hill barrens.
