Thoughtful Thursday: 300 Trees Planted at Masonville Cove

Blog-Header-ConservationExp

Last week, the National Aquarium teamed up with local school students and community volunteers to restore vital habitat right here in Baltimore City. Through the Students Restoring Urban Streams initiative, 80 student and community volunteers planted more than 300 trees in Farring-Baybrook Park, a vital part of the Masonville Cove watershed.

Located in the heart of South Baltimore, Farring-BayBrook Park is one of the largest green spaces in Baltimore City.

Since 2011, the National Aquarium has partnered with the Baltimore City Department of Recreation and Parks to plant native trees and improve the habitat in the park.

By planting trees along the small stream that runs through the park, volunteers helped to create an important buffer between the heavily urbanized communities and local waterways to help filter pollutants! These urban trees will also provide islands of essential habitat for native plants and animals and help to improve local air quality.

If you are interested in helping the National Aquarium restore Masonville Cove, join us next month for our next shoreline restoration project in the watershed.

The Students Restoring Urban Streams initiative is a city-wide project in partnership with the Maryland Department of Natural Resources, Baltimore City Department of Recreation and Parks, Tree Baltimore, Parks and People Foundation and Blue Water Baltimore.

April 2, 2014: The Sounds of Spring Peepers & Wood Frogs

A Blue View podcastClick here to listen to John discuss the
chorus of sounds produced by frogs to
attract mates during the breeding season!

Through the winter, woodlands and meadows are mostly quiet at night. But with the arrival of spring rains and warming temperatures, that silence is broken by loud choruses of wood frogs and spring peepers. These are the first frog species to come out of hibernation and begin the year’s amphibian breeding season.

Spring peepers are small, just one inch in length, but you wouldn’t know it from their sound. Each peeper can produce a call as loud as 90 decibels. Multiply that by the number of frogs in a wetland habitat, and you have a sound that can rival that of a rock concert.

Why so noisy? That’s how the male spring peepers attract females from the surrounding woodlands. As the females come out of hibernation, they are carrying between 200 and 1,000 eggs, and the females are outnumbered by the males at about 9 to 1. Competition is intense, and females choose males based on the quality of his song.

Because of this competition, males wrestle for the best spots at the chorusing site. Interestingly, Dr. Don Forester and David Lykens of Towson University discovered that some spring peeper males were successful in breeding with females through a very deceptive strategy. Because calling requires a huge amount of energy, some spring peeper males, known as satellite males, don’t call at all.

Instead, these satellite males save energy by positioning themselves near the top singers. They then intercept females moving toward the calling males. Satellite males are smaller than calling males and would probably be at a disadvantage in trying to attract females with a less impressive voice.

Though the spring peeper is often considered the first frog to emerge from hibernation and therefore an early sign that winter is indeed over, the wood frog is usually ahead of the peeper. In fact, in mild winters, wood frogs have been observed arriving in woodland pools as early as February.

Wood frogs are often referred to as “explosive breeders” because they arrive in large numbers and have a short breeding season, usually only lasting the first few weeks of late winter or early spring. Wood frogs almost exclusively lay their eggs in vernal pools, which are small temporary bodies of water that form in depressions.

Because these pools dry over the summer, wood frogs must lay their eggs, the eggs must hatch, and tadpoles must fully develop and metamorphose before the pools dry. The wood frog’s strategy is to arrive first and maximize the time needed to make it the entire way through the process. Wood frog tadpoles often dine on the newly laid eggs of later arriving frog species.

Even as these frogs perpetuate their life cycle, they do face challenges. Their well-being is intricately linked to the survival of their woodland home and their vernal pools. Be considerate of these habitats in your neighborhood by preventing trash and other pollution from traveling through your waterways. Slow down while driving on warm spring nights, allowing amphibians to migrate safely across roadways. And when you pay these amazing creatures a visit in their natural habitat, observe but don’t disturb.

Reflecting On the 25 Years Since the Exxon Valdez Spill

national aquarium Animal Rescue Update

Oil spills have been an on-going topic of interest to the public for centuries, but was rapidly thrust to the spotlight 25 years ago when the Exxon Valdez vessel grounded in Prince William Sound, Alaska and discharged 11 million gallons of crude oil.

Despite a broadened awareness of environmental risks, more stringent regulations and increased safety methods, the efforts to decrease oil spills on a global level have been largely unsuccessful.

There are multi-disciplinary studies to quantify the effects of oil on marine and terrestrial ecosystems, the wildlife that inhabits those ecosystems and the social and economic impacts to communities.  The pictures of oiled wildlife from the Exxon Valdez spill, similar to the ones from the Deepwater Horizon spill a generation later, and the recent photos from last month’s Houston ship channel spill are devastating.

The immediate threat to wildlife and the human communities that depend on healthy natural resources is obvious.  The long-term effects on our ecosystems (through direct exposure of through food chain interactions), while not as readily apparent, is equally concerning.  These emerging impacts are profound in any environment, but when the oil is released in a spawning or nursery area like the Gulf of Mexico, effects can be compounded and impact entire year classes of fish.  A recently published study found that even passing exposure to petroleum compounds can cause damages in developing embryos that may ultimately prove lethal months to years later.

Protecting wildlife from oil spill incidents, and subsequently responding to oiled animals are not easy tasks. While all plants and animals can be affected by oil spills, the most visible and easily accessible animals are typically those that are collected to be decontaminated and rehabilitated. Examples often include birds, mammals, reptiles and amphibians. Oiled wildlife response is just one small part of the overall spill response.

Our Animal Rescue team ensures our preparedness to respond to oil spill events involving marine mammals or sea turtles in our area by participating in oil spill training and drills, maintaining internal protocols, and meeting with the Regional Response Team for our area (RRT III). RRT III is a group of federal, state and local organizations that oversee written plans for response to oil spill events within the region of Pennsylvania through Virginia. These plans, known as Area Contingency Plans, include information such as: environmentally sensitive species/areas, culturally sensitive areas, high risk locations and critical infrastructure.

Our dependence on fossils fuels ensures that there will always be a risk of oils spills. To mitigate for this risk we need to understand the true cost of this dependence and take responsibility for making better life style decisions in our daily routines.

Support and implementation of cleaner energy alternatives will decrease our dependence on fossil fuels and the risk of oil spill events.

An Update on Our Animal Rescue Patients

national aquarium Animal Rescue Update

As you saw in last week’s update, 11 of our 19 sea turtle patients are stable and ready for release! We’re working closely with the National Oceanic and Atmospheric Administration, the U.S. Fish and Wildlife Service and officials from the state of Florida to set a release date for these animals!

In addition to our turtle patients ready for release, we do still have 8 active medical cases, and some of them have proven to be interesting challenges for our veterinary staff.

Here are updates on a few of our active cases!

Charlie

Charlie was previously diagnosed with an unknown mass near his heart. After his diagnosis, our veterinary staff prescribed an innovative treatment for Charlie – baby aspirin. He has been responding well to treatment, is eating well, and behaving normally.

A repeat echocardiogram (ultrasound of the heart) this week revealed that the mass is still present, though reduced in size. While Charlie is showing no clinical signs from the mass, his medical case will continue to be active until we can perform more tests to determine what the mass is, and if it is a symptom of a yet unidentified underlying issue.

Blade

Blade was admitted as a cold-stun, but also had a traumatic (possible boat strike) injury to the left side of his carapace and bottom shell that was dangerously close to penetrating through into his body cavity. The good news for Blade is that the suspected boat strike injury has completely healed, thanks to regular wound cleaning and a minor surgery.

Unfortunately, Blade is still fighting an active infection in his right front flipper, and his condition is still critical. Blade recently underwent a CT scan, and the results indicate an active bone infection in his right shoulder. Bone infections can be difficult to treat, but our Animal Health staff have been working hard to monitor and treat the infection appropriately. Yesterday, Blade underwent additional x-rays, blood work, and a sedated procedure to extract some infected cells so we can identify whether the infection is bacterial or fungal.

Our staff are keeping Blade as comfortable as possible, and doing everything they can to help him fight the infection.

Animal Rescue Update: 11 Turtle Patients Ready for Release

national aquarium Animal Rescue Update

Our Animal Health and Animal Rescue staff have been busy continuing to care for the 19 cold-stunned sea turtles currently in rehabilitation. Over the last three months, many of our patients have been treated for critical conditions, including: fungal and bacterial pneumonias, infections in their flipper joints and severe shell lesions.

I’m happy to announce that we currently have 11 turtles that are no longer on medications and are considered stable! We are now working with our partners at the National Oceanic and Atmospheric Administration (NOAA), U.S. Fish and Wildlife Service (USFWS), and the state of Florida to schedule a release date in the near future!

All the stable turtles have been getting full exams that will act as pre-release screening  exams, which include recheck radiographs, blood work, physical exams, and tagging. All releasable turtles must be tagged in some way – either metal flipper tags, a PIT tag (a microchip like your domestic dog/cat might have), or both. The metal flipper tags are applied to the rear flippers and are the equivalent of getting your ears pierced.

These tags will stay with the animals for many years after release, but may eventually fall out as they corrode or as the turtle grows. As a more permanent method of identifying the animal, we implant a small microchip under the skin that will stay with the animal indefinitely. These forms of ID are passive ways researchers can track released turtles and provide insight to migration patterns, foraging areas and past medical history.

Meet some of our patients ready for release! 

Chipper

This green sea turtle stranded in Ocean City, MD as a cold-stun and arrived to the National Aquarium with a dangerously low body temperature of only 37o F. A temperature this low in sea turtles can be fatal, and our staff had to be careful to warm the turtle very slowly over several days. In fact, he was so cold on admittance, that in order to prevent his body temperature from rising too quickly, we actually had to utilize ice to stabilize his temperature.

Chipper has amazingly made a full recovery. He was prescribed long-term fluid therapy to combat blood changes due to the cold-stunning, but otherwise has had a clean bill of health.

Goose

Goose is a Kemp’s ridley that was cold-stunned in Cape Cod and transferred to us by the New England Aquarium. Goose is the smallest turtle this season – he was admitted weighing less than 2 lbs, and is now over 3.5 lbs! He was treated for anemia (low iron), a high white blood cell count, and mild pneumonia.

While Goose is the smallest turtle we currently have in rehabilitation, he has a big personality and makes our staff laugh. He’s not ashamed to scavenge small pieces of produce from his green sea turtle neighbors, even though Kemp’s ridley’s don’t typically eat plant-based foods.

Jester

Jester is a Kemp’s ridley that also came to us from New England Aquarium. He was treated for pneumonia, shell lesions, and mild skin lesions.

Jester has gained 2 lbs on a diet of squid, shrimp, capelin, and crab while in rehab!

Stay tuned for details on their upcoming release!
