Foliage For Indoor Frogs

Frogs are one of the more common classroom pets because they are quite easy to care for and they look very cool. Growing frogs is a great way for science teachers to teach kids about metamorphosis because they can use the frog as example for this process. Frogs at first are tadpoles and then they turn into an adult frog. But there are a few things that you should know if you are thinking about raising a frog in a classroom or in other indoor spaces. One of the most important things being what type of foliage to use for the frogs as that can determine how the frogs feel in their classroom terrarium because plants provide the frogs with cover as well as help with the oxygen production in the vivarium. This foliage will be different based on what type of frog you have – an aquatic, semi-aquatic, terrestrial or arboreal (climbing or tree) frog.

Foliage for aquatic frogs
Because aquatic frogs tend to spend most of their life underwater these frogs will require to live in vivarium where there is a lot of water which means that you will have to have aquatic plants too, because regular land plants won’t be able to survive in the water or in a place where it is very moist and wet. Common plants that grow and feel well in aquatic environments are Anubias species plants, which are very durable aquatic plants; Pothos Plants and Philodendron that are long vine type plants that will nicely cover your aquatic terrariums wall; Cryptocoryne wendtii, which are tall plants with heavy foliage; as well as Anacharis plants that the frogs can use to hide among and other similar plants. But for classroom purposes you can also make a biotope aquatic tank meaning that you place all of the same plants that can be found in the natural habitat of the frog species that you have in your terrarium.

Foliage for semi-aquatic frogs
Semi-aquatic frogs are called that because they spend half of their time in the water and half on land and they need appropriate tanks with 50% of the tank being water but and the rest being land. This also means that in a vivarium for these types of frogs you can combine aquatic plants and also non-aquatic plants. Just keep in mind that these non-aquatic plants too should favor a moist environment and soil so don’t place plants that prefer dry conditions in a semi-aquatic tank. For the water portion of the terrarium you can again use the same aquatic plants that I mentioned previously, but for the land portion of the tank you can use plants like Bromeliads that will adapt to basically any environment, as well as Ferns that are high humidity plants and other plants that can stand humidity and their roots being constantly wet.

Foliage for arboreal (tree) frogs
Then there are so called arboreal or tree frogs that need a lot of climbing space meaning that their vivarium too needs to have taller plants with climbing potential. Great plants for frogs of this type are Philodendrons that grow really fast and in basically any conditions; Wandering Jews that also are quick growing plants; plants called “Golden Pothos” that is adaptable and an easy growing plant; Aglaonema genus plants that can reach up to 3 feet, as well as Marcgravia or Shingle Plant that has fat leaves and tends to climb on other surfaces; and a plant by the name of “Silver Skies” that also grows fast and has big leaves.

Foliage for terrestrial frogs
Lastly, there are quite a lot of frogs that are categorized as terrestrial or land frogs. For these types of frogs you can create a vivarium that is quite similar to one that I described for arboreal plants. However, in the terrestrial frog case they don’t need the height of the plants but rather they need bigger and longer spaces that are heavily clad with foliage because these frogs need places to hide and they are not able to climb the plants like tree frogs can. For terrestrial frog tanks you can use plants like Peperomia and Pilea plants, both are plants with many different species that are all good for terrariums, as well as Orchids because they don’t like wet places and other house plants or land plants.

One thing to keep in mind with terrariums and plants though is the light that they get because for any plant to grow they need light for photosynthesis to happen. The more light plants get the faster they grow, so make sure that in the classroom the frogs are placed in a spot where it gets natural lighting. An alternative of course, which in many cases might be even better than natural light, is to install t5 grow lights or any other similar artificial lights above your terrarium, because with these artificial lights the plants as well as the frogs will get the light and heat they need and you will be able to control the conditions in the terrarium so that they are just perfect for the species of frogs you have.

Environmentalism: It’s up to YOU to teach the young

It’s December and there are just 11 days left for children to enter the 2015 kids art contest, and all ages to enter the photo contest. As I watch artworks and photos trickle in, I’m wondering (as I did in 2013) why aren’t more people participating? (read >> The Young Environmental Artist)

I see a pattern here. The climate talks are on in Paris, but most are just talkers and not doers. It’s not enough to “like” and share pictures and articles on social media, and not actually do something to show you care.

My own Jersey City made me proud last year with close to 200 students from 17 schools submitting artworks. In addition, we received artworks from 17 states in the US and 32 countries around the world. The total last year was close to 1000 pieces of creative expression. It was marvelous! The winning artworks were celebrated online and in 3 well received exhibitions including an exhibition in Jersey City’s City Hall.

Jersey City is a culturally active area with a large artist community, and yet these same artists, many who have children, aren’t participating either. So, I’m back to wondering why it’s easier for me to reach parents and teachers in other countries and not those in my own area?

I’m asking you now… educators and parents to explain to the young why they should care about wildlife and the environment and I’ll continue to do my part to help amphibians and the environment too.

Please make me proud by entering today!

How Bd has impacted Arizona’s amphibian species

A Frogs Are Green eco-interview with Nick Massimo and Evan Brus.

When was your organization founded? Please tell us a bit about its/your mission, goals… When did you first begin this important work?

Evan and I are both PhD students studying the disease dynamics of a deadly fungal pathogen that infects amphibians all over the world. The pathogen is Batrachochtrium dendrobatidis (Bd), and it causes the disease called chytridiomycosis. This disease was first noticed in the late 1980s and early 1990s as a wave of mass amphibian mortality events swept through Central America. Further research linked Bd to mass amphibian die offs and the extinction of multiple amphibian species all over the world.

Recent research has created a picture of how this pathogen may have originated in Brazil and spread to North America over 100 years ago. The oldest amphibian specimen that’s tested positive for Bd was in Illinois in 1888. Then, in the 1920s Bd was detected in California. Approximately 50 years passed before Bd was detected again in southern Mexico in 1972. The detection of Bd in Mexico was then tracked south into Central America where researchers first noticed the dramatic effects Bd could have on amphibian communities. The goal of our project is to better understand how Bd spread in the Americas, possibly passing through Arizona and to determine how this pathogen has impacted Arizona’s numerous amphibian species.

What is your educational background and what lead to wanting to specialize in this area and/or create your organization?

Nick Massimo

I received a BS in biology and nutritional sciences and a minor in chemistry from the University of Arizona in 2011. After I graduated with my BS I spent two years working on numerous research projects studying species such as the Gila monster (Heloderma suspectum), desert tortoises (Gopherus agassizii), fungal endophytes (fungi that live inside plants), and several other herpertofauna species from the southwestern United States. I gained these experiences working with the University of Arizona, the Arizona Game and Fish Department and a not-for-profit group, Friends of Saguaro National Park. The combination of knowledge I gained from mycological and herpetological research in Arizona provided a great platform for me to pursue my PhD at Arizona State University studying how a fungal pathogen affects Arizona amphibians.

Evan Brus

I received my B.S in Zoology, French, and Environmental Studies from the University of Wisconsin Madison in 2011. During and after college, I worked in a social insect behavior lab studying the signals and cues that regulate nest construction in Polybia occidentalis, eventually traveling to Costa Rica to do research there. While studying for an ecology course, I happened upon the book Extinction in Our Times by my current advisor, James Collins. I was immediately intrigued by the story of amphibian declines, and I applied to do my PhD in his lab at ASU the following year.

Who would say has influenced you or your work?

Nick Massimo

I was inspired to pursue a career in biodiversity conservation by my early childhood experiences where I spent time with my family enjoying the great outdoors. Through these experiences I developed a deep appreciation of our beautifully complex natural world. The time I spent at the University of Arizona pursuing my BS continued to guide me to pursue a career in conservation due to some of my wonderful professors. Dr. Robichaux, Dr. Bonine and especially Dr. Arnold helped provide me with fantastic experiences and mentoring opportunities at the University of Arizona. Towards the end of my bachelor degree I received an internship with the Arizona Game and Fish Department. My advisor, David Grandmaison, introduced me to a wide array of projects focusing on conservation strategies for mammal, bird, reptile and amphibian species in Arizona.

After I graduated, I received a job with my most influential mentor, Dr. Betsy Arnold. During my time working with Dr. Arnold, I gained a large amount of experience on how to develop, conduct and conclude an intricate research project working with fungi that live inside of plants. Without the help and mentorship Dr. Arnold provided me, I would not be where I am today. Dr. Arnold has been my most influential mentor.

Evan Brus

Like many biologists and ecologists, I grew up with a deep appreciation for nature. I was lucky enough to live in a relatively rural area of Wisconsin surrounded by streams and forests, which I relished as a child. My early experiences exploring the outdoors informed my initial choice to study biology, but I credit several college professors for helping me refine my interests and encouraging my work. My undergraduate research mentor Dr. Robert Jeanne, as well as his grad students Ben Taylor and Teresa Schueller, taught me the culture of academia and the skills needed for data collection, analysis, and eventual publication. Without my experiences in this research group, I probably would not be a scientist today. My other major influence was Dr. Calvin DeWitt, who taught my introductory ecology course with fervent enthusiasm and took personal interest in all his students. I learned from him how to pursue my passions and how to visualize the myriad connections between humans and the natural world in everyday life. Currently, I draw inspiration from the broad community of scientists researching amphibian decline and chytridiomycosis, too many to name. The quantity and quality of research produced in our field is remarkable, and everyone is willing to help one another and collaborate. It’s a very welcoming and dedicated community.

Please share the details of your work: the medium, technique and discoveries.

Our project will analyze how Bd may have been introduced into Arizona and how its introduction could have shaped Arizona amphibian distributions. In order to investigate these questions amphibian specimens housed in natural history collections will be assessed for the presence of Bd. Our work will determine at what time were certain species infected with Bd in the state, and do these historic infections help us understand the dramatic decline of leopard frog species in Arizona.

Our work will rely on testing amphibian skin for the presence of Bd DNA. In order to do this, we will swab amphibian specimens stored in natural history. DNA extractions will then be performed following protocols used by other researchers who have recently completed similar projects analyzing museum specimens. After DNA extractions are complete, real time PCR will be used to determine if fungal pathogen DNA is present and if so, quantify the pathogen load on the specimen. Once all of this data is collected we will gain an understanding of the disease dynamics of Bd in Arizona. This information will help determine when this deadly pathogen arrived in Arizona, what species of amphibians it infected after it arrived across time, and a possible mechanism that brought it to the state (e.g. invasive species, the bait trade etc.). Finally, this information will be used to help establish management plans to mitigate the spread of this pathogen in amphibian populations that are currently infected with Bd and also provide critical information on how to keep Bd out of populations that are currently uninfected.

We have not started our project yet. Other researchers who have recently completed similar projects have discovered Bd on amphibians in natural history collections in the past. Their work has helped us form our hypotheses on how Bd may have entered Arizona as it spread south into Mexico and Central America. Based off of a previous project we know that Bd was found on a Chiricahua Leopard Frog in Arizona as early as 1972. We would like to conduct an extensive project to discover the very important disease dynamics of Bd in Arizona, that’s why we are trying to raise funds for our research with the Instrumentl crowdfunding campaign (https://www.instrumentl.com/campaigns/history-of-a-deadly-disease-in-arizona-amphibians/).

What has been the most exciting discovery?

As we reviewed recent research conducted by other scientists we were intrigued to learn that this fungal pathogen has a very complex history. Unraveling the history of this extremely deadly amphibian disease is made even more moving as amphibians are the most threatened Class of vertebrates on the planet (IUCN Red List Report 2015). This information paired with recent research indicates that amphibians are experiencing extraordinarily high extinction rates currently than they have in the past. We find this information extremely motivating, as we’d like to conserve amphibian biodiversity for the well being of ecosystems and for our future generations.

What are some challenges you have faced and how did you deal with them?

The biggest challenge we are currently facing is obtaining funding to conduct this important project. The scientific field as a whole has been experiencing a shortage of funds to carry out extremely important research projects, and our field is no different. To combat this issue, we are currently exploring new avenues to fund our research endeavors. This is where the crowdfunding campaign (https://www.instrumentl.com/campaigns/history-of-a-deadly-disease-in-arizona-amphibians/) comes into play. We are trying to reach out to our community more directly and get them engaged with our project. We’d like to communicate the challenge we, as scientists face, as well as the challenges amphibians are now incurring.

How do you reach your targeted audience?

Is it through your website, exhibitions, advertising or social media or another route? Which is most effective and why?

We are exploring a variety of options to engage our audience. We have been reaching out to our close colleagues, research and herpetology community directly through word of mouth and email to generate support for our project. Additionally, we have also used social media (Facebook and Twitter) to gain support for our research project. Both of these avenues have provided support for our project but we’d like to reach more people. To do this, we are contacting people and groups located within Arizona to convey that this project will directly impact the amphibian biodiversity of our state and in other parts of the world.

How do you keep the audience engaged over time?

We’ve created a Facebook group (https://www.facebook.com/groups/905234229573944/) to keep our audience up to date on the progression of our research project as it’s being conducted. This will keep our audience up to date on the current status of our project and the exciting discoveries we’re making. In addition to our Facebook group, we are also planning to present the results of our study in a scientific journal article and present this information to our community in a series of talks.

What can we do to inspire the next generation to want to help the environment and the wildlife?

The information we gain from completing this study will directly lend to the construction of effective amphibian biodiversity conservation strategies. Without the help from our next generation we are at risk of losing much of the amazing amphibian biodiversity on our planet. The Frogs Are Green organization could be a wonderful partner in helping us to spread our project to its supporters. We feel that this organization can help reach a younger and broader audience than we’ve been able to reach thus far. In order for the meaningfulness of our research to be effective we need our next generations to know about the wonderful and beautiful amphibian biodiversity our planet has to offer.

What can people do to help? Donate and/or share to your cause/work?

We would be most appreciative if individuals would pledge to share our campaign with friends and colleagues using social media. We hope to reach as many people as possible because we feel the current state of our planet’s amphibian biodiversity is at a critical point. As a community we need to act now to preserve these species to maintain healthy ecosystems and for future generations. Sharing our campaign would help us reach our goal however we would be extremely thankful if people would also donate to our project so we can conduct this extremely important research.

Frog color patterns and the lack of color on the ventral surface

Frogs are a component of an exclusive cluster of the animal realm that have a part in the subtle equilibrium of both the ecosystem and the food chain. Frogs can be seen more or less any place apart from Antarctica. The majority of frogs are found in tropical areas and more frogs are found in the hotter countries. There are approximately 4,740 species of frogs on the planet. They are in fact remarkable creatures that come in a huge range of sizes as well as colors.

Frogs generally eat insects such as flies, as well as, worms and small fish. In some cultures, frogs are believed to bring good luck. Noticeably, some frogs, such as the poison dart frog, have an adequate amount of toxin in their miniscule bodies to take the life of a human being. Some species of frogs are capable of changing their skin color, and a few of them have a similar skin color as their environment.

Without a doubt, frogs have several natural predators. Generally frogs are responsive to predators, which is why frogs put down a lot of eggs at a time. A few of the main predators of frogs are comprised of reptiles, like snakes and lizards. Some fish will eat frogs, and birds will also eat frogs. Frogs are always in danger of predators and unfortunately, humans also eat frogs. Luckily, frogs have developed many techniques for defending themselves from these predators.

The color patterns of frogs and their lack of color on the ventral surface, allow frogs to escape from predators. Usually, the underside of the frog is a lighter color than the top side for the reason that if the frog is hanging on top of the water and a predator is searching for a frog, the suns glare makes the frog difficult to spot. There are shady marks on the bottom and as a result it doesn’t expose the silhouette of the frog. Some of the frog’s upper side is darker since when swimming in the underneath of a dark pond, so it coordinates with the bottom.

Frogs have a huge range of skin colors and patterns, which indeed help them from their natural predators. Colors can aid as a warning to predators that the frog may be toxic. Some frogs have the ability to change the color of their skin to adjust their heat soaking up rate, which assist them in managing their temperature. Just like other creatures, a frog’s skin and its color can be a sign of poison. Eating a blue frog can be deadly. So, the blue colored frogs offer a sign that they are not edible.

Some studies have shown that the techniques for getting the better of a predator rely on the species of frog, but several of these resistances contain the utilization of color. It is found that some of the frogs have developed patterns on their backs that bamboozle or confuse aerial predators. The patterns cover up the shape of the frog; as a result, the predator doesn’t identify it as something safe to eat.

The largest parts of frogs are not dangerous, but there are some frogs that take advantage of poison as a self-protection tactic. Research reveals that some frogs have deadly poisons that could make a human harshly sick, or even kill someone. The toxic frogs such as the poison dart frog generally have brightly colored skin that stands as a caution. The toxic frogs have in fact very few predators. Frogs such as the barred leaf frog have light patterns on their legs and body. So, when the frog runs, these patterns will make the predator puzzled.

The animal kingdom makes use of a lot of tactics in order to save themselves from predators. Frogs are amazing and they use a lot of techniques to fool predators. Basically the upper surfaces of frogs are dark and go with their environment so that they are hidden from predators viewing them from above. The ventral surfaces of most of the frogs are normally a light color so that it will be disguised against the lighter sky while observed from underneath.

On land, a frog’s enemies will attack them from above and therefore, the color on its upper side serves as concealment. In water, the frog is susceptible to assault from below. For the most part, frog’s ventral surface is seldom uncovered to the sight of predators, so these surfaces don’t require camouflage. Frogs have a variety of patterns and colors that protects them from natural predators and harsh environments.

Isolated from Africa to many tens of millions of years, Madagascar has developed its own peculiar fauna and flora, dramatically different from that of other land masses, near and far.

Similarly colonization by man, which took place on a massive scale only for two thousand years, has seen the mix of elements Africans, Asians, Arabs and Europeans who have forged a culture of “metissage” composed of no less than 18 ethnic groups each with its particular history and traditions, have in common the basic language of Indonesian origin and the cult of the dead, called “famadihana”.

Unfortunately Madagascar is also a land of great contrasts, with widespread problems of social and economic. The days that pay special attention to aspects concerning the natural wealth and cultural diversity of this island, home to the intervention of researchers that deal with biodiversity and personnel working in health, showing how much Italy is engaged in this country.

The Benefits of Frogs in Your Garden

Frogs and toads, just like so many other animal species, are suffering a decline in numbers. This is due to environmental problems, climate change and human factors and show that the changes we are seeing in the environment are signs that something is wrong.

What many people should realize is that frogs need to be viewed as an important part of the ecosystem.

Frogs and toads are not only very beautiful and diverse (Frogs per Wikipedia – approximately 4,800 species); they can also prove to be very beneficial for your garden.

Every ecosystem is comprised of multiple species that create a chain. It is what keeps the balance in nature and what maintains life as we know it. As such, frogs and toads have their place under the sun and should be protected. This is the reason why you will do very well to ensure that frogs can find shelter in your garden. If you provide the right conditions and features for these amphibian creatures, they should appear.
Frogs are good bioindicators. There is a lot that you can learn from the frogs in your garden. Frogs can show you that something is wrong in the area, or if they are happily breeding and living in the area, then everything should be okay. If you are dedicated and want to have a perfect garden, you can use the indications from frogs to know if the conditions in your garden are good, or if the frogs that used to dwell there suddenly go missing, you will know there is a disturbance.
Pest control – frogs are amazing at cleaning the garden from harmful insects. If you are having such problems, you can easily eliminate them by introducing frogs among your plants. A single frog can eat over 100 insects, such as caterpillars, sow bugs and cutworms and more. These can destroy your entire garden if left unchecked. With frogs around, you won’t need to use harmful pesticides, either.

Toads and frogs can be one of the best solutions for your garden. Not only will you have a garden safe of bugs and insects, but you will also have very pleasant amphibians hopping around.
