Mosses on Science Friday

While doing some lab work today I was listening to a podcast of Science Friday from NPR. They mentioned a new web-video that had been posted about moss landscaping. I have posted it below or you can click here to check out the video at the SciFri website.




It is a nice video and has some good information if you are interested in encouraging mosses to grow in your yard. I especially like the hand drawn graphics that illustrate moss rhizoids. All of the science they discussed sounded solid. I think that they did their fact-checking well, which is always nice to see.

Typically when I meet people and tell them that I study mosses people respond with, "Oh, I have moss growing in my yard. Do you know how I can get rid of it? " I could start to outline all the ways in which mosses are fabulous and why you would never want to eliminate them. However this usually does not sway people. Instead I say, " Yes I know what you will need to do. 1) You need to change the pH of the soil by adding lime, but it is hard to do that for any large area and you might then need a lot of lime. 2) You probably have a wet area with poor drainage, which you need to fix to make the soil drier. And 3) you should cut down all the trees in your yard. The mosses will not be able to handle the sunlight and the grass will grow better. " This last statement usually results in a jaw-dropping reaction from most people and a statement that they could not possibly cut down their trees. Then they are much more open to learning to love, like or tolerate the mosses. I then go on to tell them that moss landscaping is becoming more and more popular and they should join the trend.

They also make the same the three points in the video. That pH, water, and sunlight are the main things to consider when trying to convert your lawn into a moss covered area. I also second their point about the low-maintenance nature of a moss lawn. By not requiring a weekly mow a lot of fossil fuel energy can be saved. What do you think, is a moss lawn in your future?

Berry Go Round #18

The latest edition of the plant carnival Berry Go Round has been posted at Foothills Fancies. This month's carnival focuses on both edible and un-edible plants!

As the base of the food chain plants are the source of all of our fabulous foods. Bryophytes however are not often eaten. They do make sugars via photosynthesis. However their cell walls are not easily broken into to release these compounds. Also they can have secondary compound inside their cells that make them un-palatable and quite icky tasting. So when in a pinch I would not recommend trying to eat bryophytes.

The Bug Mosses - Buxbaumia sp.

This was one of the interesting mosses that we saw on the Bioblitz a couple of weeks ago. It is a member of the genus Buxbaumia and is most likely Buxbaumia aphylla. There are 4 species in this genus that can be found in North America and this is the only species one of the four that has been found in Connecticut. If you are hiking just a little further north in Massachusetts you might run into both B. aphylla and B. minakatae. The way to tell these two apart are by the following sporophyte features, which are mature in the springtime.

Buxbaumia aphylla
- Capsule glossy/shiny
- Capsule with a ridge separating
the Upper side from the Lower

Buxbaumia minakatae
- Capsule dull

- No ridge. Upper and Lower sides gradually merge.

The shiny capsule can be better seen on the second photo. It looks pretty dull in the first, but I think that is just the lighting. Both of the photos show the lighter upper side of the capsule that is bordered by a ridge that separates it from the lower side.

The common name for mosses in the genus Buxbaumia is the bug moss. This name refers to the off-kilter (asymmetrical) sporophyte capsule that kind of resembles a bug.

Another fact of note about members of Buxbaumia is that they have a very reduced gametophyte. They never form a leafy plant. Instead they have persistent protonema, which consists of thin filaments that may remind you of algae, if only you could see them. These protonema do produce sex organs (antheridia and archegonia). Add a little water to the mix and a sporophyte is produced via sexual reproduction. Since there is no leafy gametophyte for Buxbaumia the sporophytes appear to be sticking out of the bare soil as you can see in the photo below. Most mosses have a persistent gametophyte that is large and the sporophyte stays attached to it through its life. Since it lacks this feature this makes Buxbaumia a bit of an odd-ball.


If you have ever seen insects displayed in a natural history collection or museum they are mounted on pins stuck through their body and then poked into the bottom of a lined box. That is what I think the Buxbaumia sporophytes resemble. Specifically, they remind me of stink bugs, which one of my former office-mates studied for his dissertation. Keep your eyes peeled for this cool moss the next time you are out walking. They are a nice little find.

Corticolous Mosses at Bioblitz 2009

The Bioblitz a couple of weeks ago went well. I think that we counted about 40 bryophyte species and 40 lichen species in the survey area. We were in both Keney Park in Hartford, CT and in a floodplain area of the Connecticut River. I got some good shots of some pretty cool corticolous mosses. A moss that is corticolous grows on tree bark. Many of them had sporophytes peeking out from amongst the green, as you can see from the photos below.




In the floodplain area that we visited there were tons, I mean tons, of mosquitoes and poison ivy. I have encountered worse mosquitoes before. When I went on a field course to the Bahamas as an undergraduate I was eaten alive by mosquitoes over the two week course. I counted and had hundreds of bites on one leg. However the poison ivy on this Bioblitz excursion was more than I have ever seen before. Knee and hip high patches galore. Vines climbing almost every tree. I often went to bush a branch out of my way only to realize that it was not coming from the tree but from the poison ivy attached to it.

Here is a photo of me hiding from the mosquitoes in my rain jacket. Can you spot all the poison ivy in the background?


The poison ivy is above my head and to the right.

Thanks to Dr. Emmanuël Sérusiaux for taking this photo.

British Bryological Society Publications

I recently became a member of the British Bryological Society. They publish the peer-reviewed scientific journal called the Journal of Bryology. They also have another publication called Field Bryology, which includes a variety of articles. There are articles about new species, moss poems, notes on conservation concerns, book reviews, and much more. You can download some of the articles from this publication at the BBS website.

I think that the Field Bryology's colorful photographs and accessible writing style makes this a great publication for interested amateur bryologists. Their website has a large number of other resources. I would highly recommend checking it out if you are in search of additional bryophyte information on the web. They also list the many field-trips that they have to look at bryophytes across the English countryside. The community appears to be really active and I think that it is great that they get out into the field so much.

Speaking of field trips, we will be out in the field this weekend for the Bioblitz 2009 in Hartford, Connecticut. For more information check out the link at the side bar or drop me an email (jessica.budke@uconn.edu) if you are interesed in joining us. All are welcome.

Bryology Outdoors

I have decided to add an additional heading to the left side of this blog entitled "Bryology Outdoors". I realized that I know about a number of outdoor field-trips and workshops that focus on bryophytes. A few of them are local here in Connecticut, which I will be attending. Others are further afield, such as the SO BE FREE 15 in New Mexico, which I may want to attend, but may be a little far for my travel budget this year.

Back in the Swing of Things

Busyness has kept me away from the blogging in the past couple of weeks. The semester has wrapped up and I will not be teaching over the summer, which is a relief to my schedule. I took a week off to visit my family in Ohio. No mossy stories to report from there, but it was great to have a vacation!

I also heard back about the grants that I applied for back in March. I am thrilled to report that I received all four of the grants! Let me tell you that this was quite a surprise. Grants to fund research in the biological sciences are highly competitive. (For grant applications to the National Science Foundation ~15% of the grants are funded.) Often researchers apply multiple times before receiving funding for their research. Thus I am excited and honored to be awarded the funding from these national and international competitions. It is great to know that others in my field think that my research ideas are exciting and interesting. I am looking forward to a summer filled with research on my mosses that will entail a lot of electron microscopy.

Here is a list of the awards I received and links to the funding agencies.
Stanley Greene Award: International Association of Bryologists (1 of 3 awarded)
Graduate Student Research Award: Botanical Society of America (1 of 13 awarded)
Graduate Student Research Fellowship: American Microscopical Society (1 of 1 awarded)
Henry N. Andrews Endowment Fund: University of Connecticut Ecology and Evolutionary Biology Dept.

Also I will be giving a Moss Walk at New Pond Farm in West Redding Connecticut on Saturday May 30th. Check out their webpage here for more details.

Moss Poem

I came across this poem in the field journal of the British Bryology Society. I thought that it was appropriate timing to post as May Day is tomorrow. I think that it is a great poem of spring celebration! The warm weather is definitely upon us here in Connecticut. The layout in the original has several words spaced out and hanging out in space. I tried to have blogger space them out. However it kept sliding them back to the right no matter what I tried. Thus the dots (...) that I have added as place holders were not in the original version. I have added them to try to approximate the author's formatting as close as possible.

One more week of classes and then a week of final exams. Once the semester is over I am looking forward to getting outside to take some moss photos to post up and comment about on the blog. Until then enjoy the poetry of spring!



The Tundra Terrarium

(May Day, May Day)

My ............. sings! .................................... heart
These new things:
Pollen flings .............................................. first
Microscopic moss
Telescoping stems

Voluptuous, starburst moss

Little tinker-bell lilies
Spotted fawns
Spotted fawn lilies
Caribou antlers on caribou ferns,
Shed for the gentler season
Innocent inocybe
Cleopatra's Calyptrae
Sophocles' Sporophytes
My seen mycena tips its cap
Mushroom mycelium,
My ceiling
The forest is my floor
Earth Bursts


You! - concrete people!
You who live in the city
Have you no thirst?
This little bug
This pollywog .......................................... hand
This quenching,
Quenched land
Plant a plant that stretches
Up and up for the sun
Plant a plant that turns
Its back to darkness
Yearning for the light:
Spindly-dwindly

Your soul is suffering for lack of light
Come out, where souls take flight!

Website All About Liverworts

I just heard about this new website entitled, "ELPT: Early Land Plants Today - Uniting Taxonomy, Nomenclature, & Geography". It is a web resource devoted to information on liverworts (Marchantiophyta), one of the three groups of bryophytes.

This webite has a really extensive literature list that includes 12,000 references about liverworts. There are also links to a few taxon pages with sketches of the species. Additionally there is an extensive list of liverwort checklists. A checklist has all the species in a particular group of interest, plant or animal, that occur in a specific region or area of the world. The area a particular checklist covers can be as small as a local park or as extensive as an entire country. They are a good resource for discovering what species occur in your neck of the woods.

Mosses Outside My Apartment

I was sitting in the park next to my apartment building a few days ago and took these photos.



What do you think?

1) The mosses grew like this on the fence bar.
2) They jumped up there to get a better look at the river.
3) People have fun arranging mosses in the park.

I vote for #3. I thought that it was pretty fun to think that someone arranged the mosses in a very decorative manner. But I wonder how many people have seen them and thought that they just grow on the fence like that naturally. I have seen mosses growing on a number of man-made items. However these ones have huge chunks of sand sticking to the bottom of each clump, which makes me think that they were relocated.

I will definitely be on the lookout for more moss relocation "art" in town.
