Gleanings of the Week Ending November 7, 2015

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.

The Chemistry of Blood – When I do nature hikes for elementary school children about soil or rocks I always ask them what makes soil or rocks look red (some of them know that it is iron) then I comment that there is iron in our blood too….and that locks it for almost all of them. One time a boy answered my original question with one word: ‘blood’ – thinking he would get a disgusted reaction from me and he was really surprised when I told him the red came from iron in both cases!

Vitamin D pill a day may improve exercise performance and lower risk of heart disease – More evidence that more of us probably need Vitamin D supplements. It’s one I have been taking the past few year.

300 million-year-old 'supershark' fossils found in Texas – Lots of things are ‘large’ about Texas.

The Benefits of Getting Older – They define ‘old age’ and any age over 60! Are you surprised by any items on the list?

Greenland is Melting Away – How they take measures of the ice sheet from the ground…supplementing what can be determined from satellites and drones. The graphics of the rivers on the ice sheet are mesmerizing.

Hunting down hidden dangers and health benefits of urban fruit – When I read the headline I was braced for a lot of negative news…but it turns out that urban fruit is good overall.

Butterflies Weaponize Milkweed Toxins and Wing structure helps female monarch butterflies outperform males in flight – There were two stories about Monarch Butterflies in the news this week….and I saw one – probably migrating – as I was hiking with second graders this week!

Be Mesmerized by the Shifting Complexity of our Sun – The full video is a little over 30 minutes…and there is music too!

The Chemistry of Fireworks: Bangs, Crackles & Whistles – Color gets a lot of attention when it comes to fireworks. This post from Compound Interest is about the other things we enjoy about fireworks.

Hungry for Change: Deer Management and Food Security – Our area has a huge deer population and we have the chomped trees and bushes in our yards to prove it! The idea of combining deer management and food security may be something more communities should consider.

Milkweed in October

Milkweed is one of my favorite photography targets in the fall and the meadow as Mt. Pleasant Farm is my favorite place to find them. The heavy rains last week washed many of the pods clean. Those seeds left in the pod got very wet and now are cemented into the pod

Or the pod was not quite open enough to let them out before the deluge (I wondered if the pod would split open and the seeds would eventually disperse normally with their bits of fluff carrying the away with a breeze).

There were milkweed bugs but they didn’t seem as numerous as in previous years.

The best pictures this year were the few seeds that had dispersed - a little – but were covered with small water droplets. The structure of the fluff is jeweled! The very last picture of this group is my favorite. It was draped over a dried seed head of another plant – caught there long enough to catch the dew and drape around the structure enough to hold the seed aloft.

There were a couple of milkweed pictures in last month’s post about the Howard County Conservancy’s Mt. Pleasant Farm. The milk weed bugs have grown!

August 2015 Road Trip

Our August road trip was from Maryland up to New York (south and south west) primarily for waterfalls in New York State Parks from a base in Mt. Morris NY. I have several subsequent posts planned about the state parks. I’m focuses on the drive itself today.

Our first rest stop had Monarch friendly milkweed among their plantings….but no butterflies.

The sunflowers were in all stages of development and harbored quite a few different insects:

Bees

Wasps

And wheel bug (with a much smaller fly).

Several other rest stops along the way had similar plantings.

My husband was driving leaving me free to take pictures while we were moving down the road. The drive through the middle of Pennsylvania is through the Allegheny Mountains so there are sections of raised highway and

Steep road cuts.

The day we drove up was sunny (and hot) with fluffy clouds building.

On the way back it was somewhat cooler because it was cloudy much of the time. The high humidity made it feel hotter than it was. I manage to get a picture of the replica of the Statue of Liberty on an old bridge support in the Susquehanna River as we zipped past.

Zooming - August 2015

I did lots of hiking with campers in August…and managed some local photography jaunts (like the Butterfly exhibit at Brookside Gardens). As I was creating the collages for this month, I started experimenting with a better way to upload them…so click on any collage below to see a larger version of it! Some highlights of the zoomed images this month are:

• Feather in the grass
• Butterflies and moths
• A toad
• Milkweed pods infested with ?
• Crabapples on the ground before they could mature
• Water droplets on a leaf after a rain storm
• Lichen and moss
• Empty wasp nest
• Golden rod
• Water lily
• Magnolia seed pod

 Enjoy!

 

Mt. Pleasant Farm - August 2015 (part 1)

I was at the Howard County Conservancy’s Mt. Pleasant Farm earlier this week to lead a nature photography activity for their campers (ages 5-12). By the end of the day I had over 1600 photos from the children that I needed to review during the evening and a few of my own. Now that I’ve had a chance to review my own - there are a few worth sharing via this blog….in the same order that I took them so they do reflect the hiking we did.

Just behind the nature center a large limb had been cut recently.

We went past the bee hives…down the hill…past the butterfly garden

And stopped to look at the mossy logs that have fallen over the stream.

Then we walked along the path toward Hodge Podge Lodge. The goldenrod was starting to bloom along the grassy path.

The shingles of Hodge Podge Lodge caught my attention….lichen, moss, and leaves.

The path to the side of the Lodge down to the stream looked wet from the rain the night before.

And we started to close the loop by walking toward the community garden. I didn’t notice the bugs on this plant until I was looking at the photos…and have not identified the plant or the bugs!

We started the hike for the second group on the path downhill from the back of the nature center. This red bud was early on the trail….with lots of seed pods.

The jewelweed was near the stream.

The mile a minute seems to be taking over this bird house.

Back up the hill and down the road toward the meadow - we stopped in the old orchard. The apples were beginning their turn to red.

There was lots of milkweed pods (still green) in the meadow….and some had beetles.

And every flower seemed to have an insect of some kind.

To be continued in Sunday’s blog post…

Zooming - July 2015

I enjoyed traveling over the past month and many of the places provided ample opportunity for some close photography. Some highlights in this set of zoomed images are:

• Bluebird
• Hollyhocks
• Bees
• Cone flowers
• Milkweed
• Butterflies
• Dragonfly
• Poppies
• Red yucca pods
• Swan

Enjoy!

Zooming - June 2015

The ‘zooming’ post is a little earlier than usual this month…but it was such a good month for outdoor subjects that I didn’t want to wait. Can you find:

• A wild flower?
• A garden flower?
• Dogwood?
• A wood frog?
• Rattlesnake fern?
• Garlic scapes?
• Milkweed?
• A feather?
• A goldfinch?
• Birds nest fungus?

Middle Patuxent Environmental Area

Last weekend, we hiked the Wildlife Loop Trail in the Middle Patuxent Environmental Area. It was an outing that had been on my list for this spring and it finally was at the top. It is less than 15 minutes from our house!

The trails are rustic. There are two documented trails that have different entry points. The Wildlife Loop (the one we chose to do in this first trip to MPEA) was the trail originating from the parking lot at the Trotter Road parking area. We walked along old farm roads or mowed paths. The vegetation was lush with vines - sometimes with obvious invasive plants like honeysuckle and multiflora rose...and then there was the native grapevine too. Some areas along the road had been turned into meadow and the milkweed was getting ready to bloom.

Some of the trees were kept cleared of vines and were doing very well. I always enjoy seeing the heart shaped leaves and seed pods of redbud this time of year.

One of the maples was growing very fast and this branch must have been tall enough to be above browsing by deer.

The trail meanders downhill toward the river and then back up. Close to the end - I noticed leaves with droplets of water accumulated around their edges. It was a nice finale.

I’m already planning another hike to MPEA. I want to hike the other trail…spend more time at the river’s edge…go as early as possible while it is still cool…and remember bug spray!

Gleanings of the Week Ending April 25, 2015

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.

Greenland continuing to darken - In the Water in the Western US course I am taking via Coursera they mentioned snow darkening as it melted because layers of dust that has originally been blown on a fresh surface of snow accumulated as the layer of snow melted and left the snow behind….and then I saw this article about Greenland on the same day!

Video Diary: One Tiny Hummingbird Family - If you have never had an opportunity to watch a hummingbird nest, this is an opportunity.

Milkweed and Monarch Concerns – 2015 -   Plant Milkweed for Monarchs - The key message in this post is to plant milkweed that is native to the area where you live. That’s

Welcome to Oklahoma, the State of Denial - The graphics caught my eye in this article. There were a lot of earthquakes in Oklahoma in 2014….and evidently since this article was written the state government has started to acknowledge that they are likely manmade.

The Growing Outdoor Recreation Economy - National Parks contributed $26 billion to the economy in 2014 and the outdoor recreation economy is estimated at $646 billion and included 6.1 million jobs. Along a similar trend, another article….The Science of Valuing Nature Becoming Business as Usual.

Nest Cam of the Month: Barred & Barn Owls - I take look at the nest cams. Owls are popular right now.

Putting Technology in Its Place - Technology is not always the answer…or the total answer. Often it falls short of our expectations - particularly in places that need help the most.

Ten Favorite Trees for Wildlife - A very good list. Pick ones that are native to your area.

Excessive use of dietary supplements linked to increase cancer risk - It appears that dietary supplements are too much of a good thing. The bottom line coming out of more and more studies appears to be that its best to meet nutritional needs via food rather than supplements.

Gleanings of the Week Ending March 7, 2015

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.

'Bionic' eye allows man to see wife for first time in a decade - The system is not yet advanced enough to provide high resolution vision - but it is enough to improve quality of life….and sets the stage for more development of similar devices. Certain types of blindness (caused by retina problems, not the optic nerve) are candidates for this type of ‘bionic’ eye.

Global Pesticide Map Shows Large Areas of High Water Pollution Risk - Enlarge the map in this article; what is the risk in the area where you live? In mine is high/very high…..that’s not good.

Economic models provide insights into global sustainability challenges - Making decisions based on simplifying assumptions - which is what we normally do - may not be wise. The advent to models that can help us integrate what we know about global economics, geography, ecology and environmental sciences may provide some surprising insights and lead to better decisions.

Twelve Milkweeds for Monarchs - Wow! There are a lot more different kinds of milkweed than I anticipated.

Food Additives Linked to Inflammation - Yet another reason to reduce the amount of processed food you consume.

Special Tours Offered At Mesa Verde National Park - Something to remember about Mesa Verde. My husband I enjoyed our visit almost 40 years ago and have been talking about visiting again.

Lab-on-paper developed for rapid, inexpensive medical diagnostics - Point-of-care testing is projected to expand over the next few years. Imagine not having to wait for several days to get lab results for your annual physical!

Nine steps to survive 'most explosive era of infrastructure expansion in human history' - Bottom line: The builders of infrastructure need to consider the full context of their projects….not just who will benefit.

The Chemistry of Colored Glass - Glass is one of my favorite materials. This post includes a graphic that talks about what is added to the basic soda-lime glass to create different colors of glass.

Seven strategies to advance women in science - Good points. We’ve been trying some of these things for at least the past 40 years…..maybe it is doing ALL of them that will make the difference.

F. Kaid Benfield: How to Create Healthy Environments for People - There seem to be quite a few articles this week with lists. Here is the last one! All these ideas seem to make sense….so why are they not already part of the way development takes place?
