353G: Non Fiction Alien Abduction

I read a book around 15 years ago. The author interviewed many instances of abductions. He began to notice that some of the stories of a few of them were exactly the same, and asked for the abductees to meet in person. When they met, they realized that they knew each other. They had been abducted together, multiple times, since childhood. They lived on opposites sides of the country and had never met in person, but knew each other! One of these abductees was a political figure who asked to remain anonymous for fear of ridicule.

349D: Kind slug symbiote

Trying to find a science fiction book. I think a detective ends up finding a slug-like alien inhabiting a human. Somehow discovers it’s kind and doesn’t want to hurt humans, it had to do it in order to live, possibly after crash landing on earth. Normally they are symbiote with another alien species mutually beneficial. At the end of the book, I think she (detective) lets it into her head to save it. Think sequel?

345R: They were not like us

Science fiction "They were not like us." Spaceship investigates a post-Nova star, passes a world whose civilization was destroyed with the Nova, then makes first contact with an alien ship. They aliens appear "horse like" on video. When asked about the dead world, why they did not warn the world, they reply: "Why should we care? They were not like us." The human ship captain decides not to warn the ship about the event horizon of the collapsed star, though some crew members object. He replies: "Why should we care? They were not like us."

341Z: UFO Light Causes Boy to Grow Third Arm

As you might expect, I’m searching for a book.  I probably read it in the 1978 to 1980 time frame, so publishing occurred before that.  It is possible I read the book as late as 1982, but I don’t think so.
The book may have been a Scholastic publication, but they didn’t find anything matching the rest of the description.
The book was a short story collection.  I do not remember the title or author or authors or editor.  I think the version I read was a trade paperback, borrowed from the school library.  During 1978 to 1980 I was in 5th and 6th grade.  I suppose I could write to the librarians in those schools and ask if they still have books matching the descriptions.
The story I remember from the book had a boy in probably 5th or 6th grade walking alone in the woods one evening.  A UFO appeared through the trees (maybe he was in a clearing?) and shone a blue light through the center of his chest.  Not long afterwards a third arm started growing where the light struck the boy.  He was teased at school for being different, and he thought of having the arm surgically removed.  But the arm proved to be useful when the bullies in his school started a fight with him.  He elected to keep it.  He finished the story by saying other people around the world were getting struck by the same blue light and were growing arms as well.
I do not remember the remainder of the stories in the book.  I’m not sure I actually read them; I may have had to return the book to the library.

331D: Hostile Alien Wildlife Combined With Earth’s Failures Leads To Space Colony Catastrophes

Not sure if this is one book or a series. Earth’s first colony loses touch with Earth. Without supplies they’d counted on from Earth (food, building materials, vehicles, weapons), the colonists struggle, mostly because the planet’s wildlife (plants and dinosaur-ish animals) are all deadly 24/7. The main female character is the Sheriff, who, at the beginning, has to rescue a female friend in the badlands from a large dinosaur-ish thing. Half-way through the book, the female Sheriff crash lands in the middle of the deadly wilderness. The main male character, who she doesn’t like, goes to rescue her. After a week or so and lots of peril and at least one broken leg (hers), they end up getting back safely by making a canoe out of the shell of a huge animal (and in love).

The colony has major political and leadership issues, some gun-fueled, and then Earth shows up and wants to take over everything. There’s also a creepy guy who starts a brothel and a gambling establishment and schemes to be get elected the boss. Somebody starts a stampede of the dinosaur-ish wildlife down the town's main-street in the middle of the night, and also traps the main male character in his house with a big dinosuar-ish animal by blocking the door with a programmable excavating machine.

237D: Aliens with moss-like reproduction

This was a novella contained in a large edited volume of Sci Fi short works. Since I read it in the mid 1960’s to 1971 time period and it had a library binding, it probably dates from early 1960’s.
The plot is as follows:
Humans underwent a diaspora throughout the local galaxy; then at some point colonies lost contact with each other and with Earth and cultures evolved on their own pathways. At the point in time when the story takes place, an interplanetary Human government is trying to locate old Earth colonies to bring them back into the fold. This is apparently a very desirable event for the other cultures, as they get all sorts of economic benefits by being in the human club. Thus, many civilizations of near-human look-alikes also try to get into the human federation (Yes I know, what are the chances? Convergent evolution can only do so much. )

So inspectors investigate new applications to the federation to determine if the people really are descended from ancient earth colonists. The lead character in the story is an inspector/investigator. He is following up on the investigation and mysterious disappearance of an earlier investigator. He has a copy of the previous investigator’s rather cryptic journal, which mentions “Musci” in relation to the people of the planet. Musci? Is he talking about houseflies (Muscidae)?

Turns out, the people look much like humans, but clearly are not; they reproduce by alternation of generation, like mosses and all other land plants (though it’s only really obvious to the naked eye in mosses and ferns). “Aha! Not houseflies, but mosses!” the narrator of the story thinks. (“Muscinae” is an outdated name for the mosses, now called Bryophyta.) There is a diploid generation that gives birth to a batch of haploid babies (plants do it with spores). These babies are spirited away (out of sight of nosy humans), and grow up to be either pure haploid males (one set of chromosomes plus a Y-chromosome) or pure haploid females (one set of chromosomes, one X-Chromosome). The author describes them as very handsome/beautiful, the essence of the ideal male or female. These people have sexual reproduction, give birth to diploid babies, and die. The diploid adults raise the diploid babies (if I remember correctly) and the haploid people raise the haploid offspring of the diploids.

I really would like to locate this work, to use as a side note in teaching introductory biology lectures on plant reproduction and how strikingly different it is from animal reproduction.
