A plan to boost eco-tourism on Catalina Island by increasing the number of bison has recharged a debate over the environmental impacts of the shaggy beasts
Four months on from wild storms that swept across Tasmania, Huon Aquaculture confirms it lost 120,000 salmon when a fish pen broke apart — and now concerns are growing around secrecy in the industry and escapee fish feeding on local species.
Around the world, battles are being fought to protect native wildlife and ecosystems, property and people’s livelihoods from animal invaders. Because the resources to fight these invasions are limited, natural resource agencies must prioritize their prevention, management and eradication efforts.
So how do you decide where to concentrate your efforts? Do you go for large charismatic species, such as Burmese python and feral swine, to catch public attention or for the more elusive, but no less damaging species? Do you expend resources on prevention and early detection or resolve to mitigate existing damage?
Because reducing the impacts of feral cats--domestic cats that have returned to the wild--is a priority for conservation efforts across the globe, a research team recently reviewed the animals' diet across Australia and its territorial islands to help consider how they might best be managed. The investigators recorded 400 vertebrate species that feral cats feed on or kill in Australia, including 16 globally threatened birds, mammals and reptiles. The cats feed mainly on rabbits when they are available, but they switch to other food groups when they are not. Reptiles were eaten most frequently in desert areas, whereas medium-sized mammals, such as possums and bandicoots, were eaten most frequently in the temperate southeast. "Our most significant finding was a pattern of prey-switching from rabbits to small native mammals," said Tim Doherty, lead author of the Journal of Biogeography study. "This is important because control programs for rabbits could inadvertently lead to feral cats killing more native mammals instead. This means that land managers should use a multi-species approach for pest animal control."
PIRatE Lab's insight:
Interesting diet study of feral cats. I had not thought of doing a diet analysis on them, but it makes perfect sense. It would be interesting to do a similar study here in coastal southern California.
WowTwo picnic baskets packed with 67 live giant African snails were seized by federal authorities at Los Angeles International Airport , authorities said Monday.
PIRatE Lab's insight:
Wow! Customs and Border Protection actually managed to catch the dude with two giant picnic baskets on his way to San Dimas with 35 pounds of live gigantic snails. Impressive. I think he was sitting next to me on my last flight home. Errrr...no. Now that I think about it, I am pretty sure THAT guy's 35 pounds of mollusk was marine in origin. The dripping salt water and purple squid ink decorating the seat and aisle were the give away. If only he hadn't been pre-approved by the TSA's stellar Global Entry he might have been screened and caught like Mr. Nigeria here. I guess this poor schmuck from Lagos failed to pay for his get out of jail free card.
The damming of the Santa Clara River tributary, Piru Creek, in Ventura County created the large Piru Lake downstream of Lake Pyramid. Since then, this recreation area has become a popular spot for fishing, camping, boating and outdoor enthusiasts. The United Water Conservation District maintains this local lake, but recently they have encountered a new problem likely derived from tourism. In December of 2013, The California Department of Fish and Wildlife discovered that this lake is the first southern California body of water that did not receive water from the Colorado River to be infested with quagga mussels. Quagga mussels quickly reproduce and can clog up pipes and water systems, leading to costly repairs. This shocking discovery has alerted other local lakes to beef up boat inspection for this invasive species with increased docking requirements and propositions for clean lake taxes. To minimize this infestation of non-native mussels coming to or leaving the lake, several officials now heavily test local waterways and incoming boat traffic. The origin of this species is proposed to be from recreational boaters.
A UCSD biologist studies hippos, descendants of those that escaped a drug lord's zoo, that are prospering in Colombia's countryside, for better or worse.
It's not every day that an amateur gardener's observations become the subject of scientific study. But one keen-eyed French naturalist named Pierre Gros has managed to alert professional entomologists to a long-ignored giant predatory worm invasion. In a Peer J study published on May 22, "Giant worms chez moi!" zoologist Jean-Lou Justine of the Muséu
Nutria can grow up to 2.5 feet, weigh 20 pounds and wreak destruction wherever they go. State authorities believed they were extinct but recent sightings have led to a call for the public to help.
When creatures from the Red Sea stray into Mediterranean waters, the results can be lethal. Red-Sea pufferfish colonising the eastern Mediterranean are s
This summer, Reef Environmental Education Foundation (REEF) will be hosting their 8th Annual Summer Lionfish Derby Series. Lionfish Derbies are competitions where divers and snorkelers compete to bring in the most lionfish in a single day for over $3,500 in cash prizes. Since the first derby in 2009, REEF has facilitated the removal of over 16 thousand lionfish from all around South Florida.
It’s generally accepted that invasive plants and animals are bad for biodiversity and should be eradicated. Many individuals, organizations and municipal leaders have enlisted in the battle against these non-native species - plants in particular.
Since avian vacuolar myelinopathy, or AVM, was discovered in 1994, 76 dead eagles and hundreds of coots and other water birds at Thurmond Lake alone have been attributed to the disease. The full toll is unknown, but thousands of dead ducks, geese and even an owl have been recovered at 19 lakes across six states: Georgia, the Carolinas, Arkansas, Texas and Florida.
PIRatE Lab's insight:
Non-native introductions + eutrophication of waterways + poor enforcement of non-point source runoff = ecosystem stress.
You can't really put a price on the Mississippi river and the ways its used by so many people, but saving the wildlife of Minnesota's most popular waterway may come with the price tag of just $75,000 dollars. A species of carp have been slowly making their way up north on the Mississippi River, threatening the natural species that call those waters home.
PIRatE Lab's insight:
Acoustic fences to drive away invading fish is interesting and worth a try. The worry is the 10% of the fish in the lab that are not scared of the sound. Chances are those dudes will get right through this barrier (especially when it becomes a routine sound in this system.
It’s an environmental success story on the islands off our coastline which has left even biologists involved in the project surprised.
It’s a story we first told you about last week. Efforts to save the rare Island Fox have been so successful, researchers are moving to remove them from the endangered species list.
KCLU’s Lance Orozco has the story behind the story, explaining how they made a long shot effort work.
PIRatE Lab's insight:
A fantastic summary of the efforts to recover endangered species on our California Channel Islands. This is shaping-up to become a classic example of ecosystem interactions, food web dynamics, invasive species, and novel pollutants (environmental estrogens).
