The plan outlines steps to mitigate invasive species through policy, institution-building, information management, research and education, capacity-building and public awareness.

Its problems are compounded by illegal fishing, catching of juvenile fish, and infestations of water hyacinth and the carnivorous Nile perch, which has wiped out many native fish species. Activists say lax law enforcement and a lack of political will are failing the lake, whose fisheries help feed nearly 22 million people.

While its length of 80 millimeters (3.1 inches) may not seem like much, it's massive for an earwig and impressive for an insect. Only found on the island of St. Helena in the remote southern Atlantic, experts believe the St. Helena giant earwig was pushed to extinction by habitat destruction.

Domestic dogs are not usually viewed as a huge threat to wildlife and native habitats, but according to a recent study dogs fit all three categories to be considered an invasive species and may be decimating mammals in agroforests in Brazil.

Most scientists now agree that extinction rates are between 100 and 1000 times greater than before humans existed. Working out what is driving these extinctions is fiendishly complicated, but a new study suggests that human life expectancy may be partly to blame.

Although it’s been slow to spread through Borneo since its introduction to Indonesia in 1952, new logging roads appear to be driving the species farther afield. A study in mongabay.com’s open access journal Tropical Conservation Science raises concerns that these roads may bring unintended plant colonists to new areas – putting the biodiversity of forests at risk.

This forest&#8212;dry, stout, and thorny enough to draw blood&#8212;lies just a few miles north of a rural town in the western edge of the Dominican Republic on the border with Haiti. I'm following&#8212;or trying to keep pace with&#8212;a local hunter and guide as we search for one of the world's most bizarre mammals. It's an animal few people have heard of, let alone actually seen; even most Dominicans don't readily recognize its name or picture. But I've been obsessed with it for six years: it's called a "solenodon," more accurately the Hispaniolan solenodon or its (quite appropriate) scientific name, Solenodon paradoxus.

This algae eater, popularly known as the sucker fish, is the sailfin catfish, or plecos. It is one of the most commonly purchased fish in the freshwater aquarium fish trade, and, according to recent research in The Royal Society B, aquarists often reintroduce the sucker-fish into the wild with detrimental consequences.

We now live in a world dominated by humans (the Anthropocene), whose activities on Earth are resulting in new habitats and new environmental conditions including climate change. To many, the Anthropocene is an era of environmental doom that unless reversed, will result in catastrophic reductions in biodiversity.

Journey to the Edge of Eden is one part personal memoir similar to the English naturalist Gerald Durrell and one part Florida conservation history.

Used in New Zealand to kill populations of invasive mammals, such as rats and the Australian long-tailed possum, 1080 has become an increasingly emotive issue in New Zealand, not just splitting the government and environmentalists, but environmental groups among themselves. Critics allege that the poison, for which there is no antidote, decimates local animals as well as invasives, while proponents say the drops are the best way to control invasive mammals that kill endangered species like birds and frogs and may spread bovine tuberculosis (TB).

They interact with many other species and mediate a range of ecological processes. These interactions are often interpreted in the context of ant mosaics, where dominant species form strict territories, keeping other ants out. This segregation between ant species is well-documented in monoculture plantations. Now new research published in <i>Ecography</i> has shown that these changes are driven by the replacement of rainforests with monocultures and not the arrival of non-native species.

In fact, invasives likely played a major role in the extinction of the Mauritius' most famous resident, the dodo.

The authors argue that despite numerous warnings that the Earth is headed toward an ecological tipping point due to environmental stressors, such as habitat loss or climate change, it's unlikely this will occur anytime soon&#8212;at least not on land. The paper comes with a number of caveats, including that a global tipping point could occur in marine ecosystems due to ocean acidification from burning fossil fuels. In addition, regional tipping points, such as the Arctic ice melt or the Amazon rainforest drying out, are still of great concern.

The dodo, a giant flightless pigeon, was a marvel of the animal world: now another island ground pigeon, known as the little dodo, is facing its namesake's fate. Found only in Samoa, composed of ten islands, the bird has many names: the tooth-billed pigeon, the Manumea (local name), and Didunculus ("little dodo") strigirostris, which lead one scientist to Christen it the Dodlet.

New research in the open-access journal PLOS ONE has found that in the wet season, Guam's arachnid population booms to around 40 times higher than adjacent islands. Scientists say this is because Guam, a U.S. territory in the Pacific, has lost its insect-eating forest birds. Guam's forests were once rich in birdlife until the invasion of non-native brown tree snake (Boiga irregularis) in the 1940s decimated biodiverse bird communities. Now, the island is not only overrun with snakes, but spiders too.

At least one third of the world's 6,300 known species are threatened with extinction, while at least 200 species have gone extinct over the past 20 years. Worryingly the outbreak of a deadly fungal disease, chytridiomycosis, is spreading throughout the tropics leaving millions of victims. A new study, published in the early edition of the <i>Proceedings of the National Academy of Sciences</i>, warns that there is "little time to stave off a potential mass extinction" of frogs, salamanders, and caecilians.

An invasive species, the cane toad competes with local endemic frog species and due to its high toxicity kills any predator who preys on it, including snakes, raptors, lizards, and the carnivorous marsupial, northern quoll. New research has uncovered another victim of the toad. The freshwater crocodile has suffered massive population declines due to consuming the irascible toad.

Dr. Cagan H. Sekercioglu, a senior research scientist at Stanford and head of the world's largest tropical bird radio tracking project, estimates that 15 percent of world's 10,000 bird species will go extinct or be committed to extinction by 2100 if necessary conservation measures are not taken. While birds are one of the least threatened of any major group of organisms, Sekercioglu believes that worst-case climate change, habitat loss, and other factors could conspire to double this proportion by the end of the century. As dire as this sounds, Sekercioglu says that many threatened birds are rarer than we think and nearly 80 percent of land birds predicted to go extinct from climate change are not currently considered threatened with extinction, suggesting that species loss may be far worse than previously imagined. At particular risk are marine species and specialists in mountain habitats.
