Sara and I visited the aquarium a few weeks back along with her parents. As a change of pace I decided to bring my telephoto rather than my fast prime. While I wasn’t able to get any really good shots inside because of the low light, I was able to get some satisfying close ups (like the one above) on the marine mammals outside and the birds in the Amazon Gallery. I have a full set of photos from the aquarium over at flickr.
This week we have yet another pair of mating dragonflies. The male is above grasping the female just behind her eyes with his claspers. The female is below curling her abdomen up to the base of the male’s thorax where his secondary genitalia are located.
After a bunch fiddling with plugin settings and CSS, I’m ready to unveil my new justified design for my photo galleries. Before you give me too much credit, the actual layout is all generated by the Flickr Justified Gallery plugin. I’m really happy with these new galleries look and how they make efficient use of the available space. [click to continue…]
Unlike most of the dragonfly fauna of BC which stay put all year round, Green Darners are migratory. Like Monarchs, adults migrate north in the spring and it is their offspring, who emerge in late summer, that migrate back south. You can help conserve migratory dragonflies by report sightings to the Migratory Dragonfly Partnership.
This week’s photo features some not so spotty Jellies from the Vancouver aquarium. I really like the creamy bokeh in this shot.
Like Dandelion with which is sometimes confused, Western Goat’s Beard is another member of the daisy family (Asteraceae). It can be easily distinguished from Dandelion by it’s longer involucre bracts (leafy bits just below the flowers) which extend beyond the flowers. Both species lack the central disk flowers of their more daisy like relatives and their flowering heads consist only of ray flowers. I really like this shot because you can clearly see the bilobed stigma (♀ bits) and fused anther cylinders (♂ bits) that are characteristic of the Asteraceae.
You might be wondering where Figure 1 was taken and what it has to do with polarized light. The picture shows an unfortunate water boatman that landed on the roof of my car and quickly succumbed to the high temperatures of the sun baked metal. Why would this aquatic insect be landing on a car in the first place? The answer has to do with polarized light. [click to continue…]
Like my first recap I had intended to post this sometime in January. This year I wanted to streamline my process from the kludgey mess I had been using. I’ve been successful in moving most of the data processing into R, but it did take a while. I’m now able to parse the csv from eBird containing my observations and extract the relevant information. I can then create year, and locations lists using dplyr. This information can then be used to generate graphs, html tables using xtable, or kml files using plotKML. The process is not live updating but for that to work this code would probably need to be ported into MySQL and I would probably need API access from eBird to my own observations. I’m also having an issue with each point in my exported KML file having their own individual style, which then requires some editing in Google Earth. I then still need to manually add it to My Maps before I can embed it on a webpage. I’d welcome any suggestions here for streamlining. If anyone is interested you can find a copy of my R code here.
