Prairie Dog Polygamy Pros And Cons
2013-12-05 09:09:09

redOrbit Staff & Wire Reports - Your Universe Online While polygamy can increase the risk of exposure to diseases and parasites, the likelihood that female prairie dogs will give birth to more offspring often makes mating with more than one male worth the risk, new research claims. The paper, which was prepared by behavioral ecologist John Hoogland of University of Maryland, reported that the herbivorous rodents that mated with multiple males were likely to rear more offspring...

Study Shows Impact Of Polyandry On Reproductive Success In Fire Salamanders
2013-12-02 16:11:27

University of Bielefeld Researchers at Bielefeld University and the Technische Universität Braunschweig are the first to confirm the benefit of multiple paternities for a vertebrate under completely natural conditions. Together with their team, Dr. Barbara Caspers and Dr. Sebastian Steinfartz have shown that female fire salamanders mate with several males under natural conditions (so-called polyandry). This grants them fitness-relevant benefits by increasing their number of offspring. The...

An article in the current issue of the Journal of Mammalogy provides insights into the reasons female prairie dogs copulate with several males, also known as polyandry. While the results of this study showed that this practice increases birth rates, it also can decrease the mother's chances of survival. Lawrence, Kansas (PRWEB) August 19, 2013 Female organisms commonly copulate with multiple male partners, and prairie dogs are no exceptions. The question is, why do females undergo...

Promiscuous females may be the key to a species' survival, according to new research by the Universities of Exeter and Liverpool. Published Feb. 25 in Current Biology, the study could solve the mystery of why females of most species have multiple mates, despite this being more risky for the individual. Known as 'polyandry' among scientists, the phenomenon of females having multiple mates is shared across most animal species, from insects to mammals. This study suggests that polyandry reduces...

Variety is the spice of life: too many males, too little time...Female Australian painted dragon lizards are polyandrous - that is, they mate with as many males as they can safely get access to. This promiscuous behavior is often found in species where male quality is dubious and there are high levels of infertility in the male population. Female painted dragons possess the remarkable ability to store sperm inside their reproductive tract that remain viable for a considerable amount of time,...

Honeybee queens have sex with harems of males apparently to give birth to much better dancers, research now reveals. The better honeybees dance, the better they are at hustling for chow, scientists added. Taking lots of male consorts is a dicey proposition for bee queens. For one thing, it increases their risk of catching sexually transmitted diseases. Also, if a queen's children have several fathers, they don't have as much in common with each other genetically speaking, which in...

Stegodyphus lineatus is the only European species belonging to the spider genus Stegodyphus. The males of this species are up to 12 millimeters long, while the females are up to 15 millimeters long. The coloration can range from whitish to almost black. In the majority of individuals, the opisthosoma is whitish with two broad black longitudinal stripes. The males and females look similar, but the male is usually richer in contrast and has a bulbous forehead. The species name is in...

humgruffin
  • A terrible or repulsive person.
Regarding the etymology of 'humgruffin,' the OED says (rather unhelpfully) that it's a 'made-up word.' We might guess that 'hum' comes from 'humbug' or possibly 'hum' meaning 'a disagreeable smell,' while 'gruffin' could be a combination of 'gruff' and 'griffin.'
