Increases in the diversity of parasites that attack amphibians cause a decrease in the infection success rate of virulent parasites, including one that causes malformed limbs and premature death, says a new University of Colorado Boulder study. According to CU-Boulder Assistant Professor Pieter Johnson, scientists are concerned about how changes in biodiversity affect the risk of infectious diseases in humans and wildlife. Charting the relationships between parasites and amphibians is...

Tiger Snake Size Depends On Offspring Mouth Size
2012-05-16 08:14:34

Tiger snakes in Australia are of varied size, with some isolated island populations being twice the size of those on the mainland. New research conducted by Fabien Aubret of La Station d'Ecologie Experimentale du CNRS à Moulis, published in “The American Naturalist,” theorizes that the mainland snakes eat mainly frogs and always have. When sea level rose after that last Ice Age, some tiger snakes were stranded on islands where frogs could not survive because of dry...

Critically Endangered Frogs Surviving In New Home
2012-05-03 13:14:48

The Durrell Wildlife Conservation Trust reports that a critically endangered frog species has found new hope in a new home. The conservationists reported that captive "mountain chicken" frogs that were reintroduced to the Caribbean island of Montserrat are alive and well. The mountain chicken frogs are one of the world's largest frog species, but its population has declined by as much as 80 percent in the wild.  Some of the female frogs can weigh a couple of pounds. "Due to...

Here's an anatomical packing list for making that historic trip from water to land circa 370 million years ago: Lungs? Check. Legs? Check. Patches of highly vascular bone in the skin? In a new paper, scientists propose why many of the earliest four-legged creatures that dared breathe on land carried bony skin features. The "dermal bones" within the skin, especially the bones covering the skull roof and forming part of the shoulder girdle, had a highly complex surface of ridges and furrows...

Athletic Frogs Have Faster-Changing Genomes
2012-04-13 07:59:11

Durham, NC – Physically fit frogs have faster-changing genomes, says a new study of poison frogs from Central and South America. Stretches of DNA accumulate changes over time, but the rate at which those changes build up varies considerably between species, said author Juan C. Santos of the National Evolutionary Synthesis Center in Durham, North Carolina. In the past, biologists trying to explain why some species have faster-changing genomes than others have focused on features...

The Saga Of The Long-Fingered Frog
2012-03-28 12:14:37

A single specimen of the Bururi long-fingered frog has been discovered by herpetologists from the California Academy of Sciences and the University of Texas at El Paso. The researchers discovered the Bururi frog while on a research expedition to Burundi in December 2011. This frog had been considered long since extinct, as the last time it had been seen by scientists was in 1949. Burundi is a place of interest for biologists who study the evolution and distribution of life in Africa....

Image 1 - New Frog Species Discovered In New York City
2012-03-15 09:26:58

New York City has many mysteries, however this latest has scientists scratching their heads.  How did an entire species of frog - in one of the nation´s most crowded and oldest cities - go undiscovered for as long as it did? In 2009, Jeremy A. Feinberg, a doctoral candidate in ecology and evolution at Rutgers University, heard a strange single croak as he was listening for the multiple croaks of the southern leopard frog in mating season. “I started hearing these calls,...

In the wilds of New York City – or as wild as you can get so close to skyscrapers – scientists have found a new leopard frog species that for years biologists mistook for a more widespread variety of leopard frog. While biologists regularly discover new species in remote rain forests, finding this one in the ponds and marshes of Staten Island, mainland New York and New Jersey – sometimes within view of the Statue of Liberty – is a big surprise, said the scientists...

Foothill Yellow-Legged Frog, Rana boylii
2014-09-16 08:43:34

The Foothill Yellow-Legged Frog (Rana boylii) is a small frog measuring about 1.46 to 3.2 inches. It belongs to the genus Rana within the Ranidae family. This species can be found from northern Oregon, down California’s west coast, and into Baja California, Mexico. Both the Columbia Spotted Frog and the Cascades Frog, also part of the Rana genus, reside in the northern regions of this frog’s territory. They show a preference for living in streams and rivers, and lay their eggs in masses...

Malabar Tree Toad, Pedostibes Tuberculosus
2014-09-15 16:22:26

The Malabar Tree Toad, Pedostibes Tuberculosus, is a species of toad located in forests along the Western Ghats of India south of Goa. It is small and it can be found in wet tree hollows or leaf bases that contain water. This slender frog features a moderately sized head with a pointed snout and vertical lores. The distance between the eyes is as wide as the width of the upper eyelid. The opening of the ear is well marked and is about a third of the diameter of the eye. The fingers are...

Golfodulcean Poison Frog, Phyllobates Vittatus
2014-09-12 08:59:50

The Golfodulcean Poison Frog, Phyllobates Vittatus, is a species of frog belonging to the Dendrobatidae family that is native to Costa Rica. Its natural habitats are subtropical or tropical, moist, lowland forests and rivers. It’s threatened by habitat loss. Like all members of the genus Phyllobates, Golfodulcean Poison Frogs have highly potent neurotoxin alkaloid poisons in their skin. While it’s only the fourth most toxic of the genus, the Golfodulcean Poison Frog is still a highly...

Strawberry Poison Dart Frog, Oophaga Pumilio

The Strawberry Poison-Dart Frog, Oophaga Pumilio or Dendrobates Pumilio, is a species of small amphibian poison dart frog located in Central America. It’s common throughout its range, which stretches from eastern central Nicaragua through Costa Rica and northwestern Panama. The species is frequently found in humid lowlands and premontane forest, but populations of large size are also found in disturbed areas such as plantations. This frog is perhaps most famous for its widespread varieties...

The Golden Poison Frog, Phyllobates Terribilis, known also as the Golden Frog, Golden Poison Arrow Frog or the Golden Dart Frog, is a poison dart frog that is native to the Pacific coast of Colombia. The optimal habitat of this frog is the rainforest with high rain rates, altitudes between 100 and 200 meters, temperatures of at least 26 degrees Celsius, and relative humidity of 80 to 90 percent. While in the wild, this is a social animal, living in groups of up to six individuals; however,...

  • 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.'
