You may have noticed I’m fond of ferns

~ Jnana Hodson ~ 2 Comments

I don’t remember them being common in the woods when I was growing up in the Midwest, but I’ve become fond of them since. I even devoted years to developing a fern bed beside our “smoking garden” patio at our home in Dover. At least now we’re surrounded by fabulous ones in the wild here.

Oh, yes, I’ve finally tasted fiddleheads in the springtime and like their taste almost as much as asparagus.

Here some additional facts.

  1. They predate the dinosaurs. One variety, the cinnamon fern, looks the same today as it does in 70-million-year-old rock fossils.
  2. They don’t have flowers or seeds and don’t have leaves. Those lovely green fronds are actually branches fused in one plane.
  3. They reproduce via spores rather than seeds. Spoors usually look like small dots on the undersides of the fronds. A single plant can drop millions of spoors on the ground, but few find favorable conditions.
  4. Some species are parasites, growing not from the ground but on decaying tree trunks on the ground or in pockets overhead.
  5. Their roots descend from rhizomes, a below-the-soil, horizontal stem that can range from very thin and creeping to thick and stocky.
  6. Some plants survive up to 100 years.
  7. Bracken ferns can live without any sunlight.
  8. Most ferns are resistant to cold but many also thrive in tropical zones.
  9. They make lovely houseplants that require little care. They do, however, need higher humidity than is commonly available, especially when the furnace is running.
  10. They can remediate contaminated soil and remove some chemical pollutants from the air.

 

Black flies, little black flies

Spring in Maine can be a very short season, marked first by mud season and then the black flies that descend from late April into July.

My introduction came one year in a brief stop to investigate a stunning waterfall, interrupted by a large swarm of what I thought were mosquitos. The second enlightenment came at a stop along the Airline Highway en route to Eastport. A wall of flying insects would be a diluted version.

Also known as buffalo gnats, turkey gnats, or white socks (not of the Chicago baseball kind), black flies are more than the defenders of wilderness. Take a look.

  1. They don’t seem to be a problem on windy days or along the ocean.
  2. There are actually more than 2,200 species of them, not that the ones I’ve seen ever look black.
  3. Their bites are particularly nasty or, at the least, a nuisance. Some even spread the disease river blindness.
  4. They’re found far beyond Maine. Scotland, northern Ontario, and Minnesota weigh in heavily, though Pennsylvania has been active in the battle against them.
  5. The eggs are laid in running water and are extremely sensitive to pollution.
  6. Bites are most often found on the face, hairline, neck, and back, though the pests are attracted to breathing and, thus, can enter the nose or mouth. Don’t overlook the ankles, either.
  7. They’re attracted to dark colors.
  8. They stretch the skin and then make shallow cuts with blade-like sections of their mouth before sucking blood.
  9. They’re most active for a few hours after sunrise and a few hours before sunset but totally inactive through the night.
  10. Folksinger Bill Staines made a hit of the logging camp song written by Canadian Wade Hesmworth. The line, “I’ll die with a blackfly pickin’ my bones,” rings especially true.

Does any of this sound fishy?

I’ve come a long way from the frozen fish sticks of my Midwestern youth, OK. Seafood’s a favorite part of my cuisine, which is one more reason I love living in coastal Maine. But I still have trouble telling one species from another.

So here are some starting points.

  1. Most fish fall under the taxonomic group Osteichthyes, or bony fish, meaning they have skeletons composed of bone tissue. With a diverse range of 20,000 or so species, it’s the largest group of vertebrates today and is comprised of both freshwater and saltwater members.
  2. That contrasts with the Chondrichthyes, which have skeletons composed primarily of cartilage. This group includes sharks, rays, skates, and sawfish – saltwater species of saltwater vertebrates with jaws, paired fins, and other distinctions.
  3. Jaws on fishes, by the way, are not connected to their skulls. Instead, they can shoot their mouths forward to capture prey, like a kind of spring.
  4. Fish breathe oxygen, not air. The fine blood vessels of their gills diffuse the oxygen to the fish’s membranes. In contrast, mammals rely on lungs.
  5. Since fish don’t have eyelids, except for sharks, you can’t say they sleep, but most of them do rest, either floating motionless, wedging themselves into a safe place, or even building a nest. But they do remain alert to danger.
  6. Tunas, billfish, and certain sharks are the speed champions, reaching 50 miles an hour in short bursts. In contrast, some strong swimmers maintain five to ten mph in cruising.
  7. Fish would suffocate if they tried to chew their food. So some, like sharks, have sharp teeth to hold their prey until they can swallow bits or parts whole. Bottom dwellers have large flat teeth to grind the shellfish they consume. And the herbivorous grazers lack jaw teeth but have tooth-like grinding mills in their throats.
  8. The organs of some fish are poisonous to man, while others become toxic because of compounds in their diets. Most of what fishermen catch, however, can be considered edible. I suspect that doesn’t always translate, though, as tasty.
  9. Truly fresh fish is odorless. The “fishy” smell comes from deterioration, typically when they’re not stored or preserved correctly.
  10. To hold their place in a school, fish use their eyes and a row of pores along their sides running from head to tail, called a lateral line. Special hairs in the pores sense changes in water pressure from other fish or predators. And some schools contain millions of individuals. So far, I’ve heard of no teacher at the head of the class. Do fish even have leaders?

For the record, neither starfish nor jellyfish are fishes.
