Royal Pleco (Panaque nigrolineatus)

…Also known as the Royal Panque, the royal pleco is a species of armored catfish (Loricariidae) that occurs in Brazil, Colombia, and Venezuela where it occurs in the Orinoco and Amazon river basins. Like other “plecos” Panaque nigrolineatus is a benthic feeder and feeds mainly on algae and detritus. P. nigrolineatus is widely known as one of the few fish that is capable of digesting wood, as (like termites) it has symbiotic bacteria in its gut, which are capable of breaking down the wood.

When the Ecuadorian government approved permits for an oil company to drill deep in Yasuni National Park (one of the most biologically important places ON EARTH), it was on the condition that the company undertake a roadless design with helicopters doing most of the leg-work.

However, a new report based on high-resolution satellite imagery has uncovered that the company, Petroamazonas, has flouted the agreement’s conditions, building a massive access road…

Memphis moruus coerulescens | ©Rodrigo Conte   (Foz do Iguaçu, Brazil)
Memphis moruus (Nymphalidae) is a Neotropical butterfly commonly named Hoja Azul and Mariposa Hojarasca (in Spanish), because the undersides of the wings closely resemble dead leaves. The upper side of the wings are blue with darker spots. 
This butterfly inhabits the Subtropical forests. They are found in Mexico, Central America, the Caribbean and parts of South America such as Bolivia, Peru, Ecuador, Brazil, and Colombia.

Lepidobatrachus laevis -  the Budgett’s frog
Lepidobatrachus laevis (family Leptodactylidae) is a large, stout, aquatic frog with a dorsoventrally flattened body. In both sexes the head is large and robust, composing approximately 1/3 of the total body length, and broad to make room for the extraordinarily wide jaws of these animals [1].
This frog has many common names, it is named Escuerzo in Spanish, and in English: Budgett’s frog, Wide-mouth frog, Hippo frog or even ”Freddy Krueger” frog (due to their disturbing screech and aggression [2] 
This species is known from northern, central and eastern areas of Chacoan environments: Argentina, Bolivia and Paraguay [3].

Researchers Use DNA to Learn about Tapir Behavior
by Jeremy Hance
apirs are notoriously hard to find and directly observe in the wild. Because of this, little is known about how species behave in their natural habitats. But in a study published in PLOS ONE, researchers found a way around this complication by using tapir DNA to shed light on their behavior.
The team sequenced and compared the DNA of individual tapirs to determine how related they were to one another, and in so doing, determine how far they dispersed throughout their habitat. This study marked the first time this specific technique had been used in the Amazon region…

Charismatic Minifauna: Giant Predatory Ants
by Gwen Pearson
Giant Tropical Ants (Dinoponera australis) live in South America and are….well, giant. In addition to being one of the largest ants in the world (28 mm long or; about 1.1 inches), they are also incredibly abundant in tropical forest habitats. How do these ants break the “big predators are rare” rule? Lead investigator Chad Tillberg explained the motivation for his research on this question:

When we started watching these enormous and abundant ants, it seemed really obvious to ask: What in the world are these ants eating?!  They had the reputation of being highly predacious, but could a top predator really be that abundant?  

Ants have an amazingly broad history of dietary habits; they range from fungus growers and leaf cutters to ferocious, aggressive predators like army ants. Plant-eating ants dominate tropical ecosystems, and their carb-loading habits have been hypothesized as the reason why…

Ameerega bilinguis | ©Santiago Ron   (Yasuni National Park, Ecuador)
The Ecuador poison frog, Ameerega bilinguis (Dendrobatidae), is known from the Ecuadorian Amazon Basin in Napo moist forests in the Eastern tropical Altitudinal Zone, and from the department of Putumayo in Colombia [1].
This brightly coloured poison dart frog has a granular red dorsum and a blue and black mottled venter. The degree of mottling and depth of blue color varies from individual to individual. Most Ameerega bilinguis posses a yellow spot at the top of the front and rear legs, again, the size and extent of the spots are variable. The dorsal surfaces of the limbs are dark, whereas the ventral surfaces are a variable shade of blue. There is also a white stripe that runs from the top of the forelimbs, along the top lip towards the snout. Juveniles do not possess the red granular dorsum, it is black. The red color appears steadily as the frog matures to adulthood. A golden canthal stripe may be visible [2].
