On May 10th seventeen RSMAS faculty members, including most of our Division Chairs and Deans, met for a four-hour workshop on “Why Mentoring Matters.”

In the workshop, faculty learned that Institutions with active mentoring are more likely to have productive employees with strong institutional commitment and that good mentoring of junior colleagues, postdocs, and students will lead to a more satisfying, collegial, and productive environment at RSMAS for all. A good mentor will make themselves available, give positive affirmation, actively listen, define expectations, and act as a role model for their mentees, as well as challenging and sponsoring them. In their turn, a good mentee has the responsibility to be pro-active, keep commitments, strive for excellence, and be open to both criticism and praise. An excellent quality for both mentors and mentees is to maintain a sense of humor, which is an antidote for anxiety and frustration!


Faculty discussed ideas for improving mentoring at RSMAS, including establishing a team mentoring plan for postdocs, and facilitating new faculty and postdocs in finding the right mentor for their needs.

The mentoring workshop was given by Dr. W. Brad Johnson, who is professor of psychology in the Department of Leadership, Ethics, and Law at the US Naval Academy and author of eleven books in the areas of mentoring, professional ethics, and counseling. The workshop was funded jointly by Dean Avissar and UM SEEDS (Scientists and Engineers Expanding Diversity and Success).

Been wondering what our Masters of Professional Science (MPS) students are up to? The University of Miami’s student-run Waterlust Project decided to show you!  The team created a GoPro film that highlights a few of the amazing research and internship opportunities available.

The new ‘Wetlab’ video was GoPro’s ‘Video of the Week’ last week! 

Launched in 2012, The Waterlust Project has reached more than half a million people with its 11 short films on a variety of ocean-related topics that focus on what water means to us. Their films offer a juxtaposition of academic achievement and artistic creativity that embodies the University as a whole.

Over at Waterlust we decided to produce a short film that captured some of the unique perspectives that graduate students get to experience here at RSMAS. We especially wanted to highlight the Master of Professional Science program in hopes of inspiring up-and-coming students to study the ocean. We searched around campus for things to film and were met with enthusiasm and smiles wherever we went. We lurked on lab groups, loaned cameras to field teams, brought cameras into classrooms, and went into the field ourselves. Passion, dedication, and a desire to find answers was everywhere we turned. We want to thank everybody who helped to make this film. Thank you for making RSMAS the coolest place to go to school.

The Billfish Foundation: How Anglers Can Help With Marine Conservation

There is a new buzz word going around the scientific community that is changing the way we view our roles in helping to better manage our precious resources. I am referring to the term ‘citizen scientist’ which allows anyone to take an active role in aiding scientists in the collection of important information which otherwise would not be possible. Though this concept has recently been becoming more popular, organizations like The Billfish Foundation (TBF) have been conducting such a program for more than 20 years through its tag and release program. Anglers taking participating in the tagging program have helped to provide critical information that is essential to TBF’s goal of conserving these amazing species like marlin, swordfish and sailfish for generations to come.

So why is this such a big deal? Since encountering these species is rare, TBF established the Tagging Program in 1990. TBF is proud to now hold the largest private billfish tagging database (close to 200,000 tag and release reports) because of efforts from the recreational community. Being dependent on the efforts of citizen scientist in the form of recreational anglers shows that anglers really care about the resources they are so passionate about and are willing to give back. It is through the information collected from our tagging program that provides the governing bodies with crucial information such as growth rates, longevity, migratory patterns, habitat utilization, and for stock assessment of billfish. Anyone can participate since the tags are inexpensive and effective; they just need to purchase tagging equipment from their local tackle shop or TBF’s website. A full kit of tagging equipment (tags, tag cards, tag bag, tag stick and applicator) costs about $75. The low cost and the ease of reporting the data (via mail or online) allows TBF’s traditional tagging program to annually receive over 10,000 tag and release records worldwide.

TBF’s Tag and Release Program receives about 100 recaptured tagged billfish reports a year and is proud to have some of the highest recapture rates because of the cooperation of the recreational community. One of the most exciting aspects of the program is when a recapture of a tagged billfish is reported and seeing what secrets it has to reveal. For even those who study these amazing creatures it is still astonishing to learn of some of the amazing feats they are capable of. For instance, this year a swordfish was recaptured more than 2500 miles from where it was tagged in matter of only 7 months and a white marlin that was recaptured after being abroad for more than 14 years after being tagged!

By allowing everyone to participate in research, not only does it allow TBF to receive a large amount of data each year but the participants feel connected to “their” fish, wonder where it will end up, and who might encounter it next. While most of our recapture reports are based in the Atlantic Ocean, TBF receives reports from the Pacific and the Indian Ocean (including Japan and Australia). The global success of TBF’s Tag and Release Program has been through its evolution and creating new excitement in tagging billfish. TBF engages program participants by making the data transparent – posting recaptured tag maps on Facebook, Twitter, and on the website in addition to contacting and rewarding everyone involved in the recaptured billfish. TBF encourages more anglers to tag billfish since traditional tagging data provided still provides up to 70 percent of what is known about billfish.

The Florida Everglades: Lair of the Bull Shark

Posted on by

It’s always fascinating to watch different species of fish arrive seasonally at the spots you frequent. Last weekend, while tagging sharks for research in the Everglades, it became clear to me that this very phenomenon was occurring, with blacktip sharks beginning to trickle back into the habitats, being followed around by even bigger local predators.

The Everglades is a fascinating spot to work because there are lots of predators – and those predators vary in size, number, and relative power over each other. At the apex – literally the top of the food chain – are the bull sharks. The Everglades is their lair. Blacktip and lemon sharks are also predatory sharks, but the blacktips are potential prey for the bulls, making them the proverbial “middle man on the totem pole.” The blacktips are usually the largest in number, and are often smaller than both the lemons and the bulls. Indeed, parts of the Everglades and Florida Bay give sub-adult blacktip sharks refuge from the risky, open water of the Gulf where they risk being consumed by larger predators. However, in nature, there is no free lunch, so by trading off open ocean habitats for the Everglades ecosystem, blacktip sharks gain some refuge and feeding opportunities, but subject themselves to a smaller number of large predators – the bulls – which are cruising the river mouths, coastlines, and estuarine areas for small prey. In fact, a recent study published in PLoS ONE by R.J. Dunlap Director Dr. Hammerschlag and colleauges found that bull sharks in the Everglades cause other prey species (such as tarpon) to alter their behavior when swimming through areas of high bull shark abundance. These “risk effects” are especially difficult to detect with large predatory fishes, and this study is the one of the first of its kind to detect these often overlooked measures of predator-prey relationships in marine settings. Another reason for this change in the shark presences is due to the prevailing water conditions– strong oxygen content, slightly cooler temperatures that we see from July – September, and stable salinity.

Most visits to Everglades National Park usually produce a large bull shark for our research. It is critical to establish estimates of how many bull sharks in the area, what they are eating, and if/how they can tolerate human-induced changes in the ecosystem. I encourage all of the readers to visit the Everglades and explore – the ecosystem is starting to ignite, and it is awesome to watch the predator-prey interactions between different coastal shark species. If you plan on fishing, I urge you to practice catch and release, as the seasonal blacktip aggregation already gets enough pressure from the bull sharks in the area, and the bull sharks themselves are in smaller numbers because they are the top predator. Release is a great option for these species, because both bulls and blacktips do relatively well with responsible catch and release.

Sharks: Turning Fear into Fascination

Despite the diversity of shapes and sizes in the animal kingdom, there is truly nothing like the shark. As ocean predators, they command our ultimate attention. The shark is something we learn about at a young age, a creature whose reputation becomes indoctrinated in our deep psyche likely before our first conscious foray into the ocean.

This is how I – like many others – first considered these predators. But alongside our reservations, comes a parallel sense of fascination. As I grew up, this fascination took over, and I now spend my time studying, researching, and engaging these species as much as possible.

In my film, “Coastguards,” I hope to illustrate humanity’s obsession and mixture of fear and fascination for sharks, while bringing their ecological importance – and plight – into the spot light. Told through my perspective with footage compiled from expeditions and research trips from the last 3 years, “Coastguards” is a metaphor for the role sharks play in maintaining the health and stability of our precious blue planet.
