Why we need Alternative B adopted for NPR-A

April 26, 2012 by Leave a Comment

Almost 30 years ago, Congress stated that the National Petroleum Reserve – Alaska (NPR-A) was an, “exceptional natural, fish, wildlife, scenic, cultural and historical values that warrant protection”. Situated not far from the Arctic National Wildlife Refuge, the NPR-A is now under a lot of scrutiny. As the largest federal land management unit in the nation (23 million acres, almost the size of Indiana!) the Bureau of Land Management has proposed 4 alternatives for its future.

The only one suitable for the habitat Congress hailed as exceptional 30 years ago, would be Alternative B.  Dr. Steve Zack, conservation scientist, for the Wildlife Conservation Society (WCS) – North America Program:

WCS is very encouraged to see in the planning process for western Arctic Alaska an alternative that will mean significant wildlife conservation through protection of key areas. The Bureau of Land Management`s plan for the largest public landscape in the United States, the National-Petroleum Reserve – Alaska, includes four alternatives, one of which is Alternative B. Alternative B sets aside from development the most important part of the world`s largest Arctic wetland, located around Teshekpuk Lake, and provides protection of the large landscapes across which hundreds of thousands of caribou migrate, including the Utukok Uplands region. We strongly feel that Alternative B, which categorizes areas critical for wildlife as unavailable for oil and gas leasing, balances energy development and wildlife protection in a landscape rich in both resources.

Polar bears, walruses, belugas, caribou, wolves, grizzly bears, and waterbirds all rely on the diverse habitat of the NPR-A to survive. Furthermore, for thousands of years there have been native communities living along the reserve. Please request to Secretary Salazar that these communities not be developed in order to maintain this sustainable lifestyle.

For some amazing images of the Utukok River Uplands (an area within the NPR-A) spend some time on this website. I think I’m ready to move after looking at these!

Shadowbox of seashore treasures

April 25, 2012 by 4 Comments

Today I am very excited to share with you an image created by one of my favorite photographers, Bekki Rich. She is based in Stone Harbor, N.J. (Cape May County) and enjoys “”Taking photos when the opportunity arises”. Many of her photographs feature playful patterns found along the coastline, as well as showcase her unique perspective of maritime mementos. The image below is one I was particularly drawn to because it encapsulates how Bekki collects and cherishes ocean muses wherever possible. For instance, in a cubbyhole in the shadowbox below (not in the shot) she tore a tiny piece of cardboard off a random soapbox because it had a poem she found inspiring. The poem reads:

“A childhood stroll along the beach,

The early-morning waves wash objects

Filled with history onto the sand.

Memory retains the morning light bathed in the air of the open seas

An immense calm descends”.

Author Unknown

Check out more of Bekki’s work here. I’ve also added her to my “Design | Beach Meditation” Pinterest board.

Dear Online Science Writing Community: A reminder for ‘call to actions’ because your perspective is priceless

April 24, 2012 by Leave a Comment

Journalists and colleagues are not the only ones reading your blog posts. The internet is home to where our nation’s kids are uncovering the answers to homework. But, they are also using the internet to learn more on what sparked their curiosity whilst investigating the world beyond-the-monitor. As an unanticipated consequence your amazing fact-filled posts, peppered with personal experience, are inspiring a new generation into fields in science, technology, engineering, or mathematics (STEM). It does not seem as though this is news to anyone since the response to the contributions of ‘This is What a Scientist Looks Like’ is amazing! More to my point – I ask you – the estimable Online Science Writing Community – to take advantage of the influence you have on the impressionable youths of this wonderful planet while sharing your knowledge online. Like it or not – they’re reading, but the good news is that they’re remembering and sharing what they read.

Sure your research is sent off to decisions makers to be reviewed. What if we also cut out the middle man and used your own voice to affect change? You’ve exposed surprising evidence that things we could do or don’t do day-to-day would vastly improve our lives and give our planet a more sustainable future. I’d be so much more apt to listen to a blogger than someone who was telling me that I had to do something because it’s now a law or a mandate. Even if this is something that you already do from time-to-time – keep doing it because your perspective is priceless. And if you don’t – why not?

Much of the advice that Nancy Baron proposed to scientists interested in sharing their knowledge in her book, A Guide to Making Your Science Matter: Escape from the Ivory Tower, would translate well when communicating to, not only journalists and policy makers, but also teenagers, young adults, and the curious non-STEM professional public. For instance, “start thinking about what the journalist and his or her audience needs from you: clear, concise, conversational answers“, “Stepping outside your comfort zone to reach can have tremendous payoffs“, and “While dealing with backlash is no fun, many scientists agree that the end result is often worthwhile“.

Yes, this might mean you have to come up with a pseudonym because a grant would be pulled if you were contradicting a sponsor. But, often times having an opinion can be harmless.  Take the opportunity to not only feed the public’s thirst for education with with your own personal style, but also make gentle suggestions to mold the young audience into becoming environmentally-responsible citizen. My hidden agenda might not be much of a surprise here, but I am asking you – the Online Science Writing Community – to be an influential part the environmental education (EE) movement.

What is environmental education? To me, environmental education is a holistic approach of science in practicality. But, here are some more comprehensive definitions that encompass the concept.

  • Colorado Association of Environmental Education: Environmental education is a life-long learning process that increases awareness about the environment and its systems while developing critical-thinking skills that enable responsible decision-making.
  • Program, Classroom Earth: Environmental education is the process, activities and experiences—across disciplines—that lead students to have a greater understanding of how the earth’s resources and natural systems work and interact with each other and with human-made systems.
  • Program, Common Circle: Environmental education teaches people about the natural world and how their actions may affect it. This learning may take place in a formal classroom setting or the term may be used more broadly to describe efforts to inform the public about ecosystems and sustainable living.

Given also that the 5 principles of EE are awareness, knowledge, attitudes, skills, and participation (Tbilisi Declaration, 1997), it would seem as though any blogger with a bio that integrates 1) why you are passionate about your STEM field, 2) what led you to that field, and 3) how you’ve made an impact on the field would therefore be the perfect person to continue to share important outcomes to readers for the all-inclusive EE approach. I understand that often research cannot be shared until published, but I can say that I would be much more apt to make personal decisions about my day-to-day life from the responsible people that conducted the research rather from those that regurgitated it.

Thank you to all of the hard working scientists that share your lab and field adventures online. I will continue to be amazed by your dedication and conviction. You have a unique voice and a head full of ideas worth sharing. You have the ability to affect change and I remind you to take advantage of it.

5 (more) fun facts about seahorses

April 23, 2012 by Leave a Comment

Seahorse at the National Aquarium in DC

Seahorses are a fascinating species to observe. I took my nephew to the National Aquarium in DC this past weekend and we were memorized by the  aquatic centaurian-like bony fish (pictured right).  I’ve written about seahorses in the past, and from the traffic of that post I can tell that a seahorse post is much appreciated by the BCS readers, so I thought I’d take a some time to delve into more of their hallmark traits.

Here are  5 more fun facts about seahorses to add to the list (written almost 3 years ago!). Please feel free to comment below or email info@beachchairscientist.com if you have something you’d love to share about seahorses!

  1. The genus name of the approximately 35 species of seahorses is ‘Hippocampus’. ‘Hippo’ is Greek for ‘horse’ and ‘kampos’ is Greek for ‘sea monster’. The cross section of the hippocampus in our brain is shaped like a seahorse.
  2. For over 400 years many Eastern cultures have been using seahorses in medicines to cure asthma, lower cholesterol, as well as prevent arteriosclerosis.
  3. Seahorses uses their strong prehensile tail to grasp onto sea grasses and other stable plants. They are decent (not strong) swimmers and use their snout to suck up food (plankton, as well as tiny fish and shrimp).
  4. Often storms are a threat to adult seahorses as they will pull the seahorse off its anchoring plant. Other natural threats can include sea turtles, sharks, rays, and tuna. A major non-natural threat are divers that like to scoop up seahorses for aquariums (although, many ‘seahorse ranches’ are popping up).
  5. Seahorses lack the scales that a ‘normal’ fish might have and instead have bony plates arranged as rings. The bony plates are very similar to that of the Stegosaurus. Each seahorse species has a unique number of rings.

If you want to learn more on seahorses (in particular – how humans have learned to immortalize them in artwork, literature, and myths),  I highly recommend getting your hands on a copy of Poseidon’s Steeed: The Story of Seahorse, From Myth to Reality by Helen Scales.

A naturalist’s must-see destination: Cape May County (and, the rest of south Jersey)

April 20, 2012 by 2 Comments

Earlier this year I was happy to see that the federal government had awarded New Jersey a $1 million grant to protect the ecologically sensitive wetlands in Cape May County (“Where Nature Smiles for 30 Miles” and where my hometown is located). The New Jersey Department of Environmental Protection (DEP) will use the money to purchase 140 acres to add to the existing 17,000-acre Cape May Wetlands Wildlife Management Area. These wetlands are not only where I fell in love with the natural world, but are also home to many species of migratory birds and act as a nursery for many commercially important species of fish that spawn in the estuaries.

So with a combination of my pride in the DEP’s award and my feelings that an ‘ode to home’ in the Where We Live series is long overdue, I decided to take the time to compile a list of “10 unique and interesting natural history or maritime features of south Jersey”. I am sure there are plenty more out there, so please feel free to comment below or send me an email at info@beachchairscientist.com if you have any additional comments or questions.

1. South Jersey sits to the east of the Delaware Bay. The Delaware Bay boasts the second-highest concentration of shorebirds in North America (second to Quivira, Kansas which is mid-point in the United States). The Bay is mid-point in travel for many birds that travel from the warm weather of South America up to the Arctic. The Bay is also a perfect wintering habitat for many species of songbirds and waterfowl.

2. The world’s largest population of Atlantic horseshoe crabs (Limulus polyphemus) spawn in Delaware Bay.

3. At the entrance of the Delaware Bay is the Cape May Lighthouse, built in 1859, which documents the beginning of Cape May County’s nautical history. There is also the Hereford Inlet Lighthouse, built in 1874, on the Atlantic Ocean side of the Cape May County peninsula in North Wildwood. Speaking of Cape May, the famous Cape May diamonds people have been looking for since the 1880’s are actually quartz crystals that wash up as smooth rock.

4. At 3800 Boardwalk Mall in Wildwood you can see the 43rd Wyland Whaling Wall, “Humpbacks off the Jersey Coast” (pictured right). Wyland is known as “one of America’s most unique creative influences, and a leading advocate for marine resource conservation”.

5. The A.J. Meerwald, New Jersey’s official Tall Ship, began life as a sailing schooner built for oystering,  but was commandeered during World War II to serve as a fireboat on the Delaware Bay.

6. The Stone Harbor Point is one of the few parcels of New Jersey’s coast that has not been stabilized (86% of the shoreline has been stabilized) leaving a remarkable wide open space that has been shaped (and reshaped) by waves and tides for centuries. It also has one of the last thickets of bayberry left on New Jersey’s coast.

7. The Marine Mammal Stranding Center in Brigantine has the impressive achievement of responding to over 3,900 strandings of whales, dolphins, seals, and sea turtles (all, of course, done with a permit and authorization from the state and federal governments).

8. In south Jersey you’ll also find the Pine Barrens, a distinctive natural area spanning over  1 million acres of the Outer Coastal Plain (pictured left) in southern and central New Jersey. Dr. Witmer Stone, an early New Jersey natural scientist described the area as “always sandy and thickly covered with more or less scrubby vegetation, interspersed with swamps and infested by hordes of mosquitoes”. This area is particularly prone to fires and some species, such as the rare pygmy Pitch Pine, have become adapted to the fires and count on the fires to reproduce. The sandy soil of the Pine Barrens is sometimes referred to as sugar sand.

9. Blueberries were officially named the state fruit in 2004. New Jersey produces the second most blueberries in the world (Maine is first). Hammonton is considered the “Blueberry Capital of the World”.

10. After the federal government designated the Outer Coastal Plain as an American Vinticultureal Area, south Jersey started up on the wine trend! Now south Jersey has more than 20 fully functioning wineries and vineyards.

As Jacques Cousteau said, “People protect what they love“. I am sure you can tell from this blog that I do love the ocean. This love no doubt came from growing up in south Jersey and spending time everyday at the beach or the nearby Bay.  Here’s a poem I wrote (almost 12 years ago) about the area. I hope you’re inspired to learn about the natural history of your own area – especially on this upcoming Earth Day weekend.

Cheers!

How do fish give birth? Revisited

April 19, 2012 by Leave a Comment

From time to time, I like to revisit the more popular posts and present either new material or the material in a new format. Below is a simplified understanding of the three general ways that fish give birth (i.e., Within each category below there are sub-categories that I did not get into here). Please feel free to comment below or send me an email at info@beachchairscientist.com if you have any additional questions.

What are the fastest fish in the sea?

April 18, 2012 by 6 Comments

Not too long ago, I provided an update on the fastest fish in the sea, the Indo-Pacific sailfish (Istiophorus platypterus). I thought it would be interesting to do some research on how fast this fish is in comparison to other animals on land and in the sea and create a graphic to illustrate it.  First, some notes, there are some outliers I left off the chart. For instance, the Peregrine falcon (Falco peregrinus) at 325 miles per hour (mph), as well as pretty much the entire family of swifts (Apodidae) averaging a 106 mph flying speed. Also, I am certain there are many other species of terrestrial and flying animals that can be included in this list, I only added a few to compare. Please feel free to comment below or send me an email at info@beachchairscientist.com if you have something to add to the list!

THE LIST

Peregrine Falcon (Falco peregrinus) 200 mph
Swift (Apodidae) 106 mph
Sailfish (Istiophorus platypterus) 70 mph
Cheetah (Acinonyx jubatus) 70mph
Pronghorn antelope (Antilocapra americana) 61 mph
Striped marlin (Tetrapturus audax) 50 mph
Wahoo (Acanthocybium solandri) 48 mph
Southern blue fin tuna (Thunnus maccoyii) 47 mph
Yellow fin tuna (Thunnus albacares) 46 mph
Blue shark (Prionace glauca) 43 mph
Ostrich (Struthio camelus) 43 mph
Bonefish (Albula vulpes) 40 mph
Swordfish (Xiphias gladius) 40 mph
Tarpon (Megalops cyprinoides) 35 mph
Tiger shark (Galeocerdo cuvier) 33 mph
Hawk moth (Sphingidae) 33 mph
Human (Homo sapiens) 27 mph

What are skates and how are they different from rays?

April 17, 2012 by Leave a Comment

Recently, a subscriber wanted to learn more about skates. Great question since many of us think of ‘roller’ when we think ‘skate’. Skates are a species that often get overshadowed by rays, especially considering rays tend to be boldly colored while skates tend to be rather dreary and drab in coloration. Rays are also found closer to the coast and skates prefer deep water so we may be more familiar with running into (or focused on learning to avoid) rays. However, there are exceptions to those generalizations within the 100 species of skates and 240 species of rays found worldwide.

They’re both flat diamond-shaped fish with their mouths on the underside of their body. Both of their body types can be described as dorsoventral. Skates and rays are cartilaginous fish, like sharks and chimaera, which all make up the class Chondrichthyes (Con-drick-thees). Cartilage is the material that makes up our nose and ears and is more flexible than bone. Skates and rays  have modified fins, resembling wings, and often look as though they are flying through the ocean.

Here are six general guidelines for differentiating a skates and rays.

  • The pelvic fin of skates is divided into two lobes, while the pelvic fin of rays is a single lobe.
  • The tail on skates lacks a stinging spine. Rays have a distinct, saw-edged spine found midway along their body length. (When swimming in the habitat of stingrays it is important to remember to do the ‘stingray shuffle‘.)
  • Many species of skates have bucklers (thorn-like scales along the mid-line of their back and tail. Rays typically have no bucklers.
  • The tail of skates is rather thick and compact, while rays typically have a slender and long tail.
  • Male skates have enlarged scales near their eyes and wingtips, known as ‘malar’ and ‘alar’ spines.  Male rays do not have these scales.
  • Skates live in cold waters, while rays prefer warm seas and rivers.

For more information about skates and rays, check out the ReefQuest Centre for Shark Research.

An important call for more forage fish to remain in the sea

April 16, 2012 by Leave a Comment

A report titled “Little Fish Big Impact”, written by the Lenfest Forage Fish Task Force, came out earlier this month recommending that the amount of forage fish (e.g., menhaden, herring, shad) that we take from the ocean should be cut in half. However, since forage fish have an annual value world-wide of $5.6 billion dollars and are almost 40% of the world’s commercial fish catch these suggestions might be a tough sell to get passed through many decisions makers. But, here is why it is important we do.

You may not typically think of forage fish, also know as ‘bait fish’, as being a high commodity for fishermen or as playing an imperative role in the ocean – but, they do indeed! It’s surprising how much these little fish play a role in our daily lives.

Within the marine food web we begin with the tiny microscopic phytoplankton (plants that get their energy from the sun). Phytoplankton are  then in turn grazed upon by tiny copepods and  they are then fed upon these forage fish and crustaceans that are fed on by larger fish (e.g., striped bass, bluefish) that are then fed upon by the top predators (e.g., tunas, swordfish) that then feed us. Easy, right? Well, Dr. Daniel Pauly pointed out that within fisheries what is happening today is an imbalance of ‘Fishing Down the Marine Food Web’.

Time increases toward the right along the blue arrow. Scale on the right gives the trophic level in the food web. (Pauly, 2003)

This is the concept that when top predators are removed smaller fish become more of a target. Which would mean that the average trophic level of the food web would shift (Trophic being the level an organism occupies within a food chain). Specifically, forage fish are the primary source of protein for penguins, marine mammals, cod, salmon, tuna, and even puffins. We use these species for the production of fish oil supplements, food for livestock, and food provided to the fish we’re farming via aquaculture.

The Lenfest Report provides information and recommendations to fisheries managers in a three-tiered approach that the Task Force says was lacking prior, which is why we’ve currently been able to harvest the amount of forage fish at such high levels. The three-tiered approach involves understanding the 1) dynamics of the fishery, 2)  knowledge of the status of the trends of the fishery’s predators, as well as 3) recommended management actions.

“Traditionally we have been managing fisheries for forage species in a manner that cannot sustain the food webs, or some of the industries, they support. As three-fourths of marine ecosystems in our study have predators highly dependent on forage fish, it is economically and biologically imperative that we develop smarter management for these small but significant species,” stated Dr. Ellen K. Pikitch of the Institute for Ocean Conservation Science at Stony Brook University (they led the Lenfest Forage Fish Task Force).

Most recently, managers in the Mid-Atlantic have noticed the increasing importance of forage fish and voted to reduce the annual harvest of menhaden from 183,000 metric tons to 174,000. Read more here on the report and what other measures are being done to keep menhaden levels more sustainable.

It will be interesting to see how this report impacts forage fisheries in the future. I certainly hope it does.

Check out this video from the Task Force to learn more on the importance of forage fish.

Lastly, here is a quick overview of what it means to be a sustainable fishery:

  • If we are referring to a sustainable wild fishery (one that is not farmed) it could be the measure of the abundance and resilience to fishing pressure, how well-managed the fishery is based on current research, and/or that the fishery is harvested in ways that do not harm the environment or have negative interactions with protected species as bycatch.
  • With farmed species a sustainable it is typically a measure of minimizing marine resources, preventing escapes or diseases to wild stocks, as well as ensuring that the fishery is not associated with high pollution or other ways of negatively harming the habitat.
  • For a good resource to discover what fishery is sustainable in your region,  please check out the Monterey Bay Seafood Watch.
