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!

Muscle Clocks Play a Role in Regulating Metabolism | The Scientist Magazine® - Circadian rhythms are not just from the brain! There are timekeepers throughout the body. The peripheral clock in muscles was confirmed in 2007 and it turns out that it is important to glucose metabolism. There is still a lot to learn about all the body’s timekeepers!

BBC - Future - Are hot springs the future of farming? – Maybe there is not one strategy that is the ‘future of farming’ – but this is an interesting idea that we may see in places where it can be done effectively.

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.”

In Eastern US, adult trees adapt and acclimate to local climate: Tree cores reveal flexibility, more work needed to understand mechanisms -- ScienceDaily – 14 species of trees were analyzed using tree cores from 1940-1980….shouldn’t we look at more recent tree cores too?

Bed Bugs: When Biodiversity Bites – Cool Green Science – Informative….maybe I should check for bedbugs more consistently when I travel. I shouldn’t keep relying on ‘luck’ to avoid a very bad experience.

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.

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.

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.

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.

In praise of drawing - The Painters Keys – This is post originally written in 2006 but still very applicable today. I looked more at Internet Archive for some of the ‘how to draw’ books that were mentioned in the article; it’s amazing that in a 40-year period in the 1800s so many were published.

Composting at Home – June 2018

I got a free composting bin when I volunteered with the Fishmobile; the Fishmobile was part of a larger event at a local nature center that included a composting demo. The county gives bins away as part of the demo (GEOBIN Composting System) to encourage backyard composting by residents. A Master Gardener talked about what was required to successfully compost (mixing ‘browns’ and ‘greens’ – mixing) and I felt confident enough to give it a try. The bin was packaged rolled up in a cardboard box although the Mater Gardener recommended that stakes be used to provide some structure to the bin; I remembered that I had some at home…so no barrier. The hardest part of putting it together was the tightness of the roll; the material wanted to stay rolled! It might have been easier for two people but I managed on my own. The plastic has slots and the kit came with plastic keys to fit into the slots and turn to lock the two ends together. I made it a little smaller than the maximum size. I put it under the maple tree in our back yard….positioned to the hose from the house can reach it in case it needs to be moistened during a dry period.

I had two longer metal stakes and a flag pole that had broken into two pieces to use as stakes. There were dried leaves from last fall that were already on the ground and I simply left them for the first layer of material in the bin (the area is so shady that no grass grows under the tree so I started leaving the leaves to provide some protection to the soil). Then I added some veggie and fruit scraps from the kitchen, shredded paper and cardboard. Later I added some soil from a pot that had broken.

The bin looks very large right now. It will be a challenge to keep the greens (veggie and fruit scraps, grass clippings, bush clippings) and browns (paper, fall leaves, small twigs) balanced. I might feel the need to get a shredder for the yard waste since smaller materials will decay more quickly. I’m going to get through the rest of this year without one…just to see how the well the minimalist approach to composting will work.

Howard County Composting Facility

I attended a public tour of the composting facility in the county where I life yesterday morning. There is an expansion of the facility being built now but the pilot program has been going on for several years – lots of ‘lessons learned’ being applied to the expansion that will allow more of the county – hopefully the area where I live – to have curbside compost pickup.

The part of the facility that is currently in operation starts with piles of compostables collected from homes and some farm waste (like horse manure).

After being chopped up, it is made into piles. The material is processed for about 45 days in the piles – moved around with bulldozers to get air to all the material so that the decomposers can work. The temperatures in the piles are high enough to kill seeds which is important to the users of compost as a soil enhancer.

The piles are made over two pipes that pull air from through the pile and then

Through wood chips and finished compost (the large pipe in the foreground has pipes that push air under the wood chips/finished compost on the other side) – an effective strategy to reduce odors. The only period when odors come through that filter – so far – has been after Christmas when the discarded trees are in the piles; the pine smell is not one that people are likely to complain about so kudos to the design!

While we were there, there was a pile that was ready to be moved to the area where the compost cures; the work was done with a bulldozer…making multiple trips.

The piles are covered with tarps during rains; the compost does need water, but the amount must be controlled. Run off from the piles and the area around them is controlled.

The new facility under construction will have bunkers rather than piles which will increase the capacity per area over the design in use now. The design capacity must be sufficient to handle the large volume of leaves in the fall. In my case – I wouldn’t send most of my leaves to the compost facility since I have forest behind my house that has absorbed the leaves from my yard quite well. If my area is one of the lucky ones to be included in the expanded service, I’ll decide if sending the front yard leaves to composting is easier than raking them to the forest!

Gleanings of the Week Ending July 7, 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.

BBC - Future - How we could survive on an asteroid – Harder than colonizing a planet…but mining asteroids from a colony on the moon or mars might be more feasible. Interesting to think about; it’s not full out science fiction at this point.

Stunning Data From The Bottom of the World: Antarctic Ice Loss Triples - Dan's Wild Wild Science Journal - AGU Blogosphere – The melting is mostly from warmer ocean waters melting submerged glaciers that have moved into the ocean.

Take a 3D Tour Through Frank Lloyd Wright's Taliesin West | Smart News | Smithsonian – I always like to see an article a place that I have visited…savor the memory. This post includes the link to the 3dlab site…lots of room to explore in a way that is the next best think to being there.

Illnesses from Mosquitoes and Ticks on the Rise | Berkeley Wellness – In our area Lyme disease (from ticks) is the one we worry about the most but there might be others that are going to become more problematic. Maryland has more mosquitos that usual right now…unpleasant and maybe unhealthy.

Red Meat Allergies Caused by Tick Bites are on the Rise – Aargh! I hadn’t heard of this one before.

Feeding the gods: Hundreds of skulls reveal massive scale of human sacrifice in Aztec capital | Science | AAAS – A short video and article about structures recently excavated that include skulls of human sacrifice victims as described by Spanish conquistadors.

China’s Plastic Ban Will Flood Us with Trash | Smart News | Smithsonian – Now that China isn’t accepting the plastic we throw in recycling – where is it going? Are our landfills going to be even more massive? Ideally recycling would get better (and done closer to where the material entered the system) rather than worse.

Petrified Forest National Park Becomes World’s Newest International Dark Sky Park – I’ve visited this park several times…and now it’s a dark sky site. It’s a long way from Maryland but maybe we’ll eventually get there for a star party!

Why Europe’s astronauts are learning Chinese – China is taking the steps to be the third big player in space….and Europe is planning to cooperate with them just as it does with the US and Russia.
