Cuban treefrogs invade New Orleans; clog plumbing and cause power outages

And even worse, they are devouring the much-smaller native treefrogs.

It’s pretty hard not to love a frog. But when a new kind of frog shows up where it doesn’t belong, and is the size of a human fist, and eats the smaller native frogs … well that’s not so lovable.

Such is the case in New Orleans, Louisiana, where a population of invasive Cuban treefrogs have become the first known breeding population in the mainland United States outside of Florida, according to a new study by the U.S. Geological Survey.

Adding to the unlove factor are the frog’s particular traits; which might be fine for a frog, but make it not so great for living in harmony with humans.

“Homeowners may be familiar with the nuisance species as they have noxious skin secretions, lay their eggs in bird baths and fish ponds, and they can clog plumbing and cause power outages by short-circuiting utility switches where they seek refuge,” says USGS Research Ecologist Brad Glorioso, the lead author of the study. “Cuban treefrogs grow much larger than native treefrogs, have been known to displace native treefrogs, and will even eat smaller frogs, often of their own species. A decline in native treefrogs could have consequences, since frogs act as both predator and prey in food webs.”

Native to Cuba, the Bahamas, and the Cayman Islands, Cuban treefrogs have been finding success in Florida since at least 1951. In March of 2016, palm trees were brought from Lake Placid, Florida and planted in the elephant exhibit at New Orlean’s Audubon Zoo. Elephant keepers began seeing the odd frogs shortly thereafter.

“In late 2016, reports of at least eight Cuban treefrogs of varying sizes on the grounds of the Audubon Zoo in New Orleans gave concern that a population may be establishing,” notes the USGS. “Following additional reports in 2017 of suspected Cuban treefrog tadpoles and recently metamorphosed juveniles in Riverview, a part of Audubon Park between Audubon Zoo and the Mississippi River, the USGS began investigating the likelihood of an established population.”

In a span of three months, between September and November of 2017, the USGS scientists collected 367 Cuban treefrogs in just four surveys. In addition, thousands of tadpoles have been discovered.

Nuisance to homeowners aside, the real threat is to native treefrog species, of which USGS scientists noted a lack of during their surveys, saying that “No native treefrogs were captured at Riverview, where the highest density of Cuban treefrogs were found.”

The local treefrogs are a lot smaller than their Cuban cousins, says Jeff Boundy, a herpetologist with the Louisiana Department of Wildlife and Fisheries’ Natural Heritage Program.

“The natives are about a quarter- to half-dollar-size on your kitchen window at night. These guys get up to 5½ inches (14 centimeters) in body length. You’re talking about a fist-sized frog now,” Boundy told the AP.

“Right now, the hope is that the Cuban treefrogs do not reach and become established in the large tracts of public land, including the Barataria Preserve of Jean Lafitte National Historical Park and Preserve, just across the Mississippi River,” says Glorioso.

The moral of the story? Among other things, beware of the Florida palm trees and the secret gifts they deliver.

The study was published in the journal Biological Invasions.

  25. Los Blancos, with captain Sergio Ramos suspended after deliberately collecting a yellow card in the first leg, had been looking to build on a slender 2-1 lead from that game in Amsterdam and stay on course for a potential fourth straight European triumph.

    However, after Raphael Varane’s header rattled the crossbar, Ajax raced into an early lead through Hakim Ziyech before Dusan Tadic set up David Neres for a second in the 18th minute.

    Real Madrid were forced into two changes when Lucas Vazquez and Vinicius Junior went off injured, with substitute Gareth Bale hitting the post just before half-time.

    Ajax looked to have put the tie to bed when Tadic swept in a brilliant third goal just after the hour – which was eventually given following an extensive Video Assistant Referee review to check if the ball had gone out of play in the build-up.

  26. Nice blog here! Also your web site loads up very fast! What
    host are you using? Can I am getting your associate hyperlink to your host?

  27. These three figures — William Rick Singer, Mark Riddell and Rudolph Meredith, respectively — are at the center of the nationwide scandal in which 33 parents are accused of using their wealth and means to help their children game the college admissions system.
    But those three names do not appear anywhere in the complaint text, though the document gives enough clues to make clear who is who. Instead, they are named as Cooperating Witness 1, 2 and 3, and each agreed to plead guilty and to cooperate with the government in the hope of obtaining leniency when they are sentenced, the complaint says.

  28. Trump was surrounded at Friday’s event by officials from Customs and Border Protection as well as surviving family members of those who have loved ones killed by undocumented immigrants. Attorney General William Barr was also at the President’s veto event.
    While some lawmakers including some Republicans — have argued against the President’s use of national emergency powers in this instance, the Justice Department set forth a robust defense of the President’s authority to do so in a letter to Senate Majority Leader Mitch McConnell earlier this month, according to a copy obtained by CNN on Friday.
    “The President acted well within his discretion in declaring a national emergency concerning the southern border,” wrote Assistant Attorney General Stephen Boyd, setting out the legal basis for the proclamation under the National Emergencies Act and additional statutory authorities, which largely tracks an internal memo issued by the Office of Legal Counsel at the Justice Department.

  29. Christina was born in the royal castle Tre Kronor on 18 December S. 8 December] 1626. Her parents were the Swedish king Gustavus Adolphus and his German wife, Maria Eleonora, had already had two daughters—a stillborn princess in 1620, and then the first Princess Christina, who was born in 1623 and died the following year.3] Excited expectation surrounded Maria Eleonora’s third pregnancy in 1626. When the baby was born, it was first thought to be a boy as it was “hairy” and screamed “with a strong, hoarse voice.”she later wrote in her autobiography that, “Deep embarrassment spread among the women when they discovered their mistake.” The king, though, was very happy, stating, “She’ll be clever, she has made fools of us all!”6] From most accounts, Gustav Adolf appears to have been closely attached to his daughter, and she appears to have admired him greatly.

  32. Despite residing in Germany for nearly 30 years, there are still some things I cannot wrap my mind around. I may have married a German, pay German taxes, and have German(-American) children, but I guess my US mentality still shines through.

    Like when it comes to personal space. I’ll be standing in the supermarket, in front of a shelf full of products, deliberating over the selection, and inevitably a hand will slip itself in front of my face and grab an item from the row. Many Germans seem to not have any qualms about this at all, but it still takes me aback sometimes.
