Researchers have found that polygamous birds do not evolve in the same way as birds with only one partner at a time, because having multiple partners reduces competition and spreads genes around more, even between separate populations of the same species. The scientists studied dozens of plover populations and found that there were fewer subspecies — a genetically unique population group of a species — in polygamous birds as compared to monogamous ones. The university gave the examples of plovers in Madagascar that had multiple partners.
Sexing snakes by probing still makes me nervous. Basically probing is meant to find one of the hemipenes. Kingsnakes Lampropeltis getula sometimes squirt blood from the cloaca during probing.
Not your average holiday activity, then. But the sheer variety of compelling - and largely intact - snake cultures worldwide are evidence of our remarkable and enduring fixation with these uniquely suggestive creatures. While many cultural ceremonials have since been hijacked, diluted and absorbed into tourism's mainstream, something of the snake's reputation has meant that snake rituals, for all their colour and atmosphere, have never become a staple of the tour company itineraries.
Red-sided garter snakes have a strange mating ritual. As they emerge from hibernation in spring, thousands of male snakes will desperately rush the females in an epic battle to reproduce. With up to 10, snakes living in a single den, the sight is mind-blowing as snakes literally carpet the ground.
Why do women live longer than men? Scientists and Buzzfeed listicles have given the question plenty of scrutiny over the years, but when it comes to garter snakes in Canada, the answer really is a classic: sex. Compared with females, males reach maturity earlier, but tend to stay smaller — and they die earlier, too.
The problem is that it's not as simple to find out if a snake is male or female as it is in many other animals. On the outside, male and female snakes look similar. However, with a bit of experience, there are ways to differentiate between the two.
One might think having no limbs would put a damper on the love life, but not for snakes. When a female snake is ready to mate, she begins to release a special scent pheromones from skin glands on her back. As she goes about her daily routine, she leaves an odor trail as she pushes off resistance points on the ground See Getting Around. If a sexually mature male catches her scent, he will follow her trail until he finds her.
A thing you probably hope to never find underneath your home is one rattlesnake—much less a small army of them. According to the Facebook post, the removal service was called on March 13 after a man crawled under his home to check on his cable reception and noticed the snakes. In fact, this lot was about half of what he claimed was his largest-ever snake removal job.
