A new species of mouse lemur — Microcebus gerpi or the Gerp’s mouse lemur — has been described from Madagascar. Researchers discovered the new species during biodiversity surveys in the Sahafina Forest. The discovery highlights the importance of surveying unprotected and unexplored forests. Also, the discovery underscores the need to conserve Madagascar’s remaining forests, which are threatened by slash-and-burn agriculture (or tavy in Malagasy) and illegal logging.

A Malagasy-German research team has discovered a new primate species in the Sahafina Forest in eastern Madagascar, a forest that has not been studied before.

The Sahafina Forest is only 50km away from the Mantadia National Park in eastern Madagascar, which contains a different and much smaller species, the Goodman’s mouse lemur,” commented Prof. Radespiel. In contrast, the Gerp’s mouse lemur belongs to the group of larger mouse lemurs, i.e. has a body mass of about 68g, and is therefore almost “a giant” compared to the Goodman’s mouse lemur (ca. 44g body mass).

The distribution of the Gerp’s mouse lemur is probably restricted to the remaining fragments of lowland evergreen rain forest of this region in eastern Madagascar. Continuing deforestation poses a serious threat for these animals. The researchers from Hanover/Germany, and Madagascar published their discovery together in the journal Primates.

CAN YOU SEE ME? | ANIMAL CAMOUFLAGE

This hidden, camouflaged animal is probably easy for most viewers to find, but the viper represents a newly-described species that was discovered during biodiversity surveys in a Tanzanian forest. However, the viper’s existence is already threatened due to the diminutive size of its remaining-forest habitat. It’s thought “that 150-200 species of plant, insect, bird and mammal become extinct every 24 hours.” The vast majority of those forever-lost species are certainly unknown to science.

The “beautiful, heavy-bodied bush viper” sports black and yellow zigzag markings and yellow, hornlike scales above its olive-colored eyes, Tim Davenport, the Wildlife Conservation Society’s country director for Tanzania, said in an email.

But few would be envious of this green-eyed creature’s rare status. Its forest habitat, already smaller than about 40 square miles (a hundred square kilometers), is declining due to human development and other factors, said Davenport, whose group made the joint discovery with the Science Museum of Trento, Italy.

Considering this, Davenport suspects the snake—described December 6 in the journal Zootaxa—will be listed as critically endangered by the International Union for Conservation of Nature.

VIDEO: Orphaned short-tailed fruit bat enjoys rocking himself back and forth after his mealtime

Here’s an adorable video of an orphaned short-tailed fruit bat, affectionately named Lil’ Drac, that’s being hand-raised at the Bat World Sanctuary:

Why was Lil’ Drac abandoned by his mother?

Lil’ Drac is an orphaned short tailed fruit bat (Carollia perspicillata). His mother was yet another casualty from zoo closures which are occurring across the US. Sheis a young mother who was stressed from the conditions in which she was kept, combined with the additional trauma of being captured and transferred to a new and unfamiliar environment. Consequently, she abandoned Lil’ Drac after he was born. He was found on the padded floor of the indoor flight enclosure at Bat World Sanctuary, curled up in a little ball.

You can keep up with Lil’ Drac’s progress here, and you can sponsor a bat in need here.

REDISCOVERED SPECIES: Camera trap captures image of endangered Persian leopard in Afghanistan

The Persian leopard (Panthera pardus ciscaucasica) was “long thought to have disappeared from” Afghanistan. However, a camera trap captured an image of one cat, which suggests that a breeding population may still occur in parts of the war-torn country. More via National Geographic:

The newly released photographs, taken in the fall, include this September shot of an adult leopard investigating the camera, “appearing to threaten it with canines exposed,” according to the Wildlife Conservation Society, which helped set up the camera traps. The images are “indisputable proof” that the big cat is hanging on in the region, the group said.

FISHERIES: Federal fishery enforcement agents seize 881-pound bluefin tuna from commercial fishing vessel

A fisherman’s enormous catch recently ignited a debate over whether fishers should be allowed to keep bycatch that is caught and landed without the proper permit, which would have allowed the fishing vessel to legally keep or sell the catch. Unfortunately, small-government advocates pounced and argued that the seizure was yet another example of federal government overreach and mismanagement. However, small-government advocates are either naive or are ignoring a plethora of facts and issues.

Basically, if commercial fishing vessels fish in state or U.S. federal government waters, then these fishing vessels are required to hold a permit. The permit allows the fishing vessels to use certain gear, in certain areas, to fish for, catch, land and sell certain species. For example, a fishing vessel with a groundfish permit to catch cod, haddock, and certain flounder species with a bottom trawl net can’t keep a bluefin tuna, an endangered, pelagic species, that is caught with the fishing vessel’s bottom trawl net — unless, for some reason, the permit authorizes the fishing vessel to keep the tuna. The purpose of utilizing permits is to control the number and types of fish caught in order to avoid overfishing and the economic collapse of fisheries.

Recently, a bottom trawler owned by Carlos Rafael landed a bluefin tuna weighing an incredible 881 pounds. However, since his fishing vessel’s permit didn’t allow him to keep the bluefin tuna, which was caught in his bottom trawl, the boat owner, unfortunately, had to surrender his tuna over to the feds. The commercial fishing vessel, apparently, did have a permit to keep a bluefin tuna caught and landed on a rod and reel.

Of course, debate ensued regarding whether the fishing vessel should have been forced to surrender its valuable catch, which was sold for “less than $5,000.” I believe that Monica Allen, the deputy director at NOAA Fisheries public affairs, put it best:

“We’re leaders among 45 countries in the conservation of this fish. Failure to enforce the regulations would damage our credibility internationally,” Allen said. There are not enough bluefin for those fishermen who target it as their sole focus, she added. “If trawl fishermen were allowed to keep bluefin, even when caught accidentally, that would create an incentive. If the stocks are rebuilt, this could actually become a way to catch them.”

Rafael, however, dismissed this logic out of hand. “That makes no sense, and I think that shows what they know about these fish,” he said.

Of course, seizing the bluefin tuna makes sense. If one fisher, who doesn’t have the proper permit, is allowed to keep a bluefin tuna, then more fishers would want to keep a tuna that was caught and landed without the proper permit. Furthermore, it would be a nightmare for enforcement and for efforts to conserve species that are severely depleted. Also, allowing a fisher to keep a tuna, if he or she doesn’t have the proper permit to do so, would make a mockery of the regulatory system. Obviously, such a move would also be unfair to fishers that have had their catches seized in the past or who have been fined in the past or who have had to discard bycatch overboard in the past.

No one, I imagine, wants to regulate commercial fishing, but the practice is inherently unsustainable, so regulations and plans are required. It’s true that there are many fishers that are conservation-minded, but it still takes cooperation between fishers, fishery managers, fishery observers, regulators (and regulation), and scientists to produce a sustainable fishery. No group can do it alone.

WEIRD & FASCINATING CREATURES: The diminutive fairy wasp is as small as some single-celled organisms

Image: A fairy wasp next to two unicellular organisms or two protozoans. According to Alexey Polilov, this is the “size of the smallest insect and two protozoans in comparison. (A) Megaphragma mymaripenne. (B) Paramecium caudatum. (C) Amoeba proteus. Scale bar for A–C is 200 μm.”

The fairy wasp is so small that is can lay its eggs inside the eggs of small insects. Indeed, they’re some of the smallest multicellular animals on the planet. In fact, at least one species is no bigger than some single-celled lifeforms such as amebas and parameciums, so this family of wasps “include the world’s smallest known insect, with a body length of only 0.139 mm (0.0055 in).” Apparently, they’re able to achieve their diminutive size because “95% of neurons in adult fairy wasps don’t have a nucleus.” More via Sir David Attenborough:
