13 natural remedies for the ant invasion
Ants are making their way into homes this time of year. Thankfully there are natural pest control methods to help you cope with and eliminate the problem. Plus, many of the solutions use what you already have in your cupboard!
Western Spotted Frog - Heleioporus albopunctatus
Heleioporus albopunctatus (Myobatrachidae) is a species of fat, globular burrowing frog, with granular skin, rather stubby limbs and toes with only rudiments of webbing. The body is chocolate-brown above; the back, head, sides and limbs are marked with scattered large white or yellow spots.
Endemic to Australia, this chubby frog is largely restricted to coast and ranges of south-western Australia.

Leaf-nesting Shrub Frog - Pseudophilautus femoralis
The genus Pseudophilautus consists of 65 known species, all of which are endemic to Sri Lanka. Pseudophilautus femoralis (Rhacophoridae) is an Endangered species whose distribution is restricted to tropical montane forests in central and southern Sri Lanka.
It is arboreal, and associated with the understorey of tropical moist montane evergreen forest. Individuals are found on, or under, leaves. It is very sensitive to any disturbance of its habitat. Breeding takes place via direct development, with the eggs attached to the underside of leaves, hence its common name of Leaf-nesting Shrub Frog.

TSA Tuesday: Loggerhead Musk Turtle
This week the spotlight is on the Loggerhead Musk Turtle (Sternotherus minor minor) which can be found in Central Florida, Georgia and Eastern Alabama. This shy species is highly aquatic, rarely leaving the water except to nest or occasionally bask on the knee of a cypress tree. They commonly inhabit clear limestone springs, rivers and streams. Their varied diet consists of aquatic insects, crayfish, plants, carrion, snails and mussels.

Scientists Find Evidence for Tectonic Plates on Jupiter’s Moon Europa
Scientists have found evidence of plate tectonics on Jupiter’s moon Europa. This indicates the first sign of this type of surface-shifting geological activity on a world other than Earth.
Researchers have clear visual evidence of Europa’s icy crust expanding. However, they could not find areas where the old crust was destroyed to make room for the new. While examining Europa images taken by NASA’s Galileo orbiter in the early 2000s, planetary geologists Simon Kattenhorn, of the University of Idaho, Moscow, and Louise Prockter, of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, discovered some unusual geological boundaries.
"We have been puzzled for years as to how all this new terrain could be formed, but we couldn’t figure out how it was accommodated," said Prockter. "We finally think we’ve found the answer."
Plate tectonics is the scientific theory that Earth’s outer layer is made up of plates or blocks that move, which accounts for why mountain and volcanoes form and earthquakes happen…

Fire skink (Lepidothyris fernandi)
The fire skink is a fairly large skink, a type of lizard. They are a beautiful species known for their bright and vivid coloration. Native to tropical forests in Western Africa, they live fifteen to twenty years. This species is a diurnal lizard that love to burrow and hide. This animal is a carnivore, feeding on crickets, ants, moths and other small arthropods.

Waxy Monkey Frog - Phyllomedusa sauvagii
Phyllomedusa sauvagii (Hylidae) is a large treefrog native to the Chacoan region of eastern Bolivia, northern Paraguay, Mato Grosso do Sul (Brazil), and northern Argentina.
Other common names: Painted-bellied Monkey Frog, Leaf-folding Frog, Rana Mono de Vientre Pintado, Rana Mono Chaqueña.
The skin of this frog contains natural opioids (Dermorphin and HYP6-dermorphin) that are more potent than morphine but less likely to produce drug tolerance and addiction. These properties make them ideal candidates for the doping of racehorses to enhance performance during competition; however, Dermorphin is a banned substance in equine athletes.
