Drug pollution concentrates in stream bugs, passes to predators in water and on land: Animals that eat insects in or near streams at risk of being dosed with pharmaceuticals -- ScienceDaily – Wow – the existence of macroinvertebrates in our local rivers is an indicator of water quality (the focus of the field trips with high schooler’s I’ve been doing in recent years) but those same macroinvertebrates are probably getting a healthy dose of pharmaceuticals from the water…the fish that eat them act as concentrators….and some of those fish are eaten by people.  I hope reserarchers in the US are doing similar studies to the one described in this article. It would also be good if pharmaceutical companies would develop drugs that were not excreted in a still active form.

Common Buckeye Butterfly

Last Saturday, I was at Robinson Nature Center about noon enjoying the native plant garden near the front of the nature center. When I noticed a Common Bucky Butterfly enjoying some of the fall flowers.

I took pictures from several perspectives. The colors and markings are very distinctive. It has knobs on the end of the antennae and whitish palpi between its eyes. It’s reported to like flowers with yellow centers…and that it what this individual was enjoying.

The entrance of the nature center has a nice display of fall pumpkins and squash.

I had come to the nature center earlier to participate look at macroinvertebrates in this part of the Middle Patuxent – upstream from the location for the two assessment with high schoolers earlier this week. Two differences: 1) no clams at Robinson….lots of them further down the river and 2) we found a snail…didn’t find any downstream. We found more of everything but that could have been the difference between and adult group and high schoolers….and we had more time to do the project.

HCC Fall Festival

Yesterday was the Howard County Conservancy’s annual Fall Festival at Mt. Pleasant Farm. The day started out cloudy and cool, but it cleared and was sunny in the afternoon. It was a good day to be out and after a lot of rainy days. It was still muddy enough that the hayride was cancelled for the year and there weren’t as many pumpkins, but all the other parts of the festival were ready for the event by 11…and there were a lot of people that came to enjoy the day at Mt. Pleasant.

I volunteered to help with the big map spread on the floor of the natures center. It was a big hit – just as it had been last year. The challenge once a lot of people started showing up was to remind children (and parents) to take off their shoes if they wanted to walk on the map. Nearly all the children wanted to walk on the map.

I prompted them to find where they lived…and encouraged their parents to help find where they had got to the beach or where friends lived. We figure out how to get from Columbia (where many of them lived) to Ocean City (they they’d gone to the beach) – pointing out the bay bridge that is along the route. Many lived in Ellicott City which was more challenging to find because it is not on the map and the Patapsco River is not labeled. Some children walked the Potomac River or the Appalachian trail…or stood with one foot in Maryland and another in one on of the neighboring states. One boy was able to put one foot in Maryland, DC, and Virginia! It was fun for all ages and many of the adults got into the action as well.

The permanent map on the nature center floor of the Howard County watersheds was popular too. The Patapsco River (light and dark green watersheds on this map) is often in the news because of the Ellicott City flooding but the Patuxent River drains more of the county.

After two hours of interacting with the crowds on the map…I was ready to walk around the Festival a little. I headed over to see pumpkin that had been painted. Some had already dried and been picked up, but the ones that were still on the plastic were fantastic.

Belmont BioBlitz Field Trip

I went early to help set up for the first Belmont BioBlitz for 5th graders this fall at Howard County Conservancy’s Belmont location. I arranged the discovery tables with pelts, skulls, insects in jars/acrylic, and leaves/seeds of common trees neatly framed in cases backed with cotton. Another table held reference books. The volunteers arrived and we all went out to wait for the buses. The new item for this year is a rugged tablet! Otherwise we had the usual BioBlitz backpack: ruler, tape measure, magnifiers, clip boards, some id books…things we would need in the field.

It’s good to feel that we are ready – and enjoy the morning calm as we wait for the buses.

And then the buses arrive and it all begins.

With my first group we stayed on pavement since we had one student with a cast and were using a wheel chair for her to help with the distance. We documented some trees along the entrance road and some insects on the trunks. Some geese flew to the pond as we watched, and I used the zoom on my camera to take some pictures to include with their documentation. It was the only time I got my camera out during the field trip. Otherwise the students did all the picture taking and documenting of what they found. The big find for the first group was a wolf spider.

The second group went in a different direction and said – at the beginning – that they wanted to look at plants and fungi. They documented an oak and the ivy growing on it. Then they found several kinds of mushroom type fungi. And there were some insects along the way…they were more interested than they thought they would be in insects. They were looking around for acorns and discovered a different kind of nut….and then the tree. A hickory. They got some good pictures of the nuts and leaves, and the way the leaves are on the branch…so they should be able to determine the type of hickory it is!

It was a good field trip. All the students had already done a BioBlitz on their schoolyard so were well versed with the mechanics of what to do. Belmont is a very different place than a schoolyard!

Cicada Identification

I photographed two cicadas in August. When I found the second one at home I had more time and took more pictures. I realized that I probably had enough different views that I should try to identify it. I knew it wasn’t a periodical cicada (one of the 13 or 17 year life cycle species) because it didn’t have red eyes.

I looked more closely at the markings and did some research using the Maryland Biodiversity Project website…and found it: Swamp Cicada – Neotibicen tibicen. The description they give fits perfectly: “Field marks include bright green in the wings, the white ventral area, greenish legs, and green patches on the head.”

A Record Year for Measles Cases in Europe | The Scientist Magazine® - When I was a child, the measles vaccines didn’t exist yet. It was awful. Everyone got sick with them and, for some, there were lasting consequences. I was fortunate and survived without lasting damage except for missing enough school that I never quite understood certain volumetric measurements because I completely missed when it was taught.

Which country has the most expensive education? - Are the comparisons really apples and apples…or are there some pears and oranges thrown in? It is about educations but there are a lot of variables beside cost. All countries and parents and teachers struggle with how to make education relevant to students for now and into the future.

Air Pollution Linked to Decline in Cognitive Performance – The study was done in China but I wondered if it was true in other areas of the world with high levels of air pollution (like India). The US could be vulnerable if we relax our clean air standards.

NASA’s OSIRIS-REx begins asteroid operations campaign – We were in Florida in September 2016 for the launch…so I always notice the updates about its progress.

50% of Industrial Climate Change Emissions Tied to Fossil Fuel Companies – An interview with the two authors of a recently released report: Decarbonization Pathways for Mines.

Gleanings of the Week Ending August 25, 2018

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Top 25 Birds that Scavenge – National Geographic and Top 25 Grassland Birds – National Geographic – There have been a couple of ’25 birds’ posts since I last included them in the gleanings list…I am catching up.

Image of the Day: Slimy Business | The Scientist Magazine® - Corn species in Mexico that can trap nitrogen…maybe it can be incorporated into the corn that dominates agriculture; that would reduce the amount of fertilizer required for the crop.

BBC - Future - The simple change that can save patients’ lives – Finally – there is more attention being paid to reducing noise (so many beeps and alarms) in hospitals. I’ve always wondered how they thought anyone could rest enough to recover in the hospital environment. Hopefully lighting will get some attention too….move away from the current dominance of blue tinged light for all times of the day and night.

Maple leaf extract could nip skin wrinkles in the bud -- ScienceDaily – The article contained relatively little information maybe because there is a patent pending on the formulation. There will probably be I have a red maple in my back yard and may try making a strong tea from the leaves…seeing how it feels on my skin.

Stirrings in the Muck: Fiddler Crabs, Yellow-Crowned Night Herons Locked in Climate Change Dance – National Geographic – The picture at the top of the article of the yellow-crowed night heron (which I saw for the first time in Carrollton TX earlier this summer) caught my attention…and I read the rest of the article.

Highly effective natural plant-based food preservative discovered -- ScienceDaily – Hope this lives up to its promise and becomes the food preservative of choice. The preservatives currently in use have side effects that are troubling at best.

BBC - Future - Are forgotten crops the future of food? – I have enjoyed the increase varieties of veggies I get from the CSA…and hope that we can further expand the food crops we utilize – for our health and to build more resilience into our food system which now is vulnerable because of the small number of plants and animals that we rely on.

Reverse Power Flow: How Solar + Batteries Shift Electric Grid Decision Making from Utilities to Consumers (In Depth) | CleanTechnica – I’ve started to wonder when the tipping point will occur – when there will be a mass economic defection by consumers away from big electric utilities. With small-scale solar ramping up to 20% of the new power plant capacity in the last 4 quarters and more people added energy storage to their solar arrays – maybe it is starting. It’s a fundamental shift for everyone. Maybe now is not the time to invest in utility companies unless they are buying in to that shift.

See Shells of Sea Spuds on the Seashore | Smart News | Smithsonian – I’d never heard of sea potatoes before…they are a kind of sea urchin. I had hoped the article would say something about how sea urchins respond to increasing ocean acidity. An article from last April said that purple sea urchins were already adapting. Are sea potatoes adapting too?

First biomarker evidence of DDT-autism link: National birth cohort study finds DDT metabolites in the blood of pregnant women are associated with elevated odds of autism in offspring -- ScienceDaily – A study of more than 1 million pregnancies in Finland between 1987 to 2005. The study found that autism correlated to maternal DDT…but not PCB…exposure.

Weekend in State College - Saturday

We made a last-minute decision to trek to State College PA to visit my daughter weekend before last. I had gotten a new camera the day before, so I experimented with it during the trip. The new camera is a Canon PowerShot SX60 HS and is billed as a ‘bridge’ camera in that it has a lot of features of my previous point-and-shot cameras but some added features too: optics that can accept added filters, some dials that make it easier to do some functions manually, and viewfinder + screen rather than just the screen. The optics zoom to 65x rather than 40x of my older point and shot. Enough the same that I knew I could use it immediately and give myself time to get comfortable with the new features.

We got to State College just before lunch time…decided to go out to Mexican food for lunch then walked around the campus. I started taking some architectural pictures.

When we were in my daughter’s office I took close-up pictures of the plants in the window (I think she must have selected them to remind her of Arizona).

There was a graduation ceremony that had just ended, and we saw students in robes and their parents walking around campus. I took pictures of Old Main from several angles.

Next I utilized the 65x zoom for some botanical photography.

We had walked around long enough to stop at the Creamery for out afternoon treat.  I got bittersweet mint ice cream in a cup. Yum (and not as messy as a cone on a hot afternoon)!

Belmont Hikes with Summer Campers V

The theme for last week’s summer campers at Howard County Conservancy’s Belmont location was STEM (Science – Technology – Engineering – Math). I decided to a pick some STEM related activities that were more like field work than actual hikes.

As usual there were two groups of about 15 each. The first group was the younger one; some of that group were just getting ready for kindergarten. I started out by handing a ruler to each camper.

We started by using the rulers to measure samples I’d brought in a bin (a stick and tulip poplar seedling were popular) and parts of the nearby barn. We did quick tutorials for campers that had not used a ruler before. One student measured one of the tiles – discovering that it was the same across and up/down (i.e. a square). Six campers collaborated to measure the lentil over a low window of the barn (5 feet 4 inches)! Most of the time we tried to measure in centimeters although we used both sides of the ruler.

I started a log of everything we measured on a pad of paper and clipboard.

We measured most of what we encountered on our hike including flowers, several feathers, grass, pine needles and cones, a fake rock (used to cover equipment), holly leaves and berries, a stump and and some very colorful mushrooms.

The second group campers were a little older – up to 12 years old. First, we talked about examples of science new sources (like Science Daily). I used an article about the discovery of moths roosting in hollow trees in Florida as an example. Then I showed them the information about the moth in the Maryland Biodiversity Project site…the way I knew the moth lived in Maryland as well as Florida. And we all knew there was a hollow tree nearby.

I had two small flashlights and we started out.

We didn’t find any moths but there were a lot of spider webs in the hollow tree. There was something there that kept the spiders well fed! We found a dead cicada nearby in the grass and examined it closely before we started out next activity.

The second activity with the group was to determine the height of a tree using a piece of paper and a tape measure. The technique worked but after using it for 2 trees we decided a 25 feet long tape measure for measuring trees over 125 feet tall was too painful (we measured a tulip poplar and white pine)…and it was too hot for more field work. We headed back to the air conditioning and lunch.

It was the last day of summer camp at Belmont. These STEM themed hikes were a good finale for us all. Everyone is getting ready for school to start…and the training sessions for field trip volunteers start too.
