Becoming a Scientist- What is Graduate School?

Recently I've been talking to high school students and undergrads who are excited about science but don't really know what their options are in terms of careers or graduate school. Many students think that medical or veterinary school are the only professional options in the sciences, so I figured I could put this out there.






Here in the US, we have quite a few options for higher education. Typically, after high school, students will go to four years of college, take classes, and earn a Bachelors degree (an undergraduate degree). With this diploma you can enter the working world in almost any profession. If you decide that more education is necessary, the next option is a Masters degree. In the sciences, this is typically 2 more years and includes both classes and independent research. If you decide to pursue a Ph.D. (or doctorate) this is an additional 5+ years of education- mostly independent research with some classwork required. You can do the Ph.D. after a Masters, or skip the Masters and go straight to the Ph.D. It depends on what your interests are, how much experience you have (a Masters program is a great place to get more research experience), and financial packages.

A super important fact that not enough students know about- while you typically pay for your undergraduate education, graduate degrees in the sciences are often paid for. In fact, they pay you to be a student in the program! This makes it feasible to spend these extra 5+ years of your life as a student. You won’t get paid a lot, but you also won’t have to go into huge amounts of debt. Professional programs, like to become a medical doctor or veterinarian, are not funded and most students take out loans to cover these. The expectation is you will make enough money when you start your career to pay back these loans. In reality, I don’t think I will ever make a ton of money, but I’m ok with that because I get a lot of satisfaction out of what I do. However, if I had hundreds of thousands of dollars in loans, this would be a much tougher field to be in.

How you spend your years in grad school varies widely across different fields, schools, departments, and mentors. In almost any program, grad students spend time working as teaching assistants (TAs) for undergraduate courses at their university. There is usually a full professor who teaches the course, but TAs lead discussions, lab sections, grade essays and exams, and hold office hours for students to drop in and get help. I’ve been really lucky and got to TA a field biology course in Nicaragua. I helped students design research projects, collect and analyze data, and present their findings in written and oral reports. It was a great learning experience for everyone involved!

There are also classes you have to take, and other ones you can chose to take to fill in gaps in your knowledge. Mostly grad students spend time working on their independent research, whether it is field based (like my Pacific pocket mouse studies are), laboratory based, computer modeling, or some combination. Almost all scientists spend a significant amount of time preparing their research results for publication and presenting at meetings- and applying for grants and other support to fund future research projects.

If you are a student now and are interested in science or passionate about conservation, it’s always a good idea to start thinking about what kind of job you would like to have. Find out about the people doing that job now- did the go to graduate school? What sorts of topics did they study? If you do think graduate school sounds great, start talking to graduate students. If you are in college, your TAs are a great resource. Most of us are more than happy to chat about our path to graduate school. Find out what they majored in, what kinds of internships and jobs they had before becoming a grad student. It is also a great idea to start getting research experience.

As you gain experience you will also figure out what you like (and don’t like!) and this will help guide your decisions about grad school or career paths. Do you love working in a lab? On a computer? In the field? There are so many different options, the more you know about yourself the easier it will be to navigate them. Also, getting experience is a big advantage in applying for MORE experience- and often cooler opportunities! Again, if you are in college there are often opportunities to assist a professor or grad student with their research, sometimes for course credit. Many schools offer field biology quarters, which are much more hands on than traditional lab courses. Search the web for job boards in a field you are interested in and browse them regularly. Even if you aren’t qualified or ready to look for a job yet, it’s a great way to find out what is out there. There are also often posts for seasonal field assistants. Some of these are unpaid, but it can be a great way to get some experience. I spent a summer helping catch pronghorn fawns on the National Bison Range in Montana. I lived in a 1 bedroom cabin with 5 other people and slept on the floor for a month and a half- but I spent my days in a gorgeous place with fascinating animals. This certainly doesn’t appeal to everyone, but if it does to you, it’s amazing.


It’s never an easy process figuring out what you want to do when you grow up, but you can be in a much better position to make those decisions with a little more knowledge of what is available! I took 3 years between my Masters and beginning my Ph.D. to really figure out what I wanted to do. There’s nothing that says you need to know right now where you want to go, and there is always a way to change your course if you find something new you love. Graduate school- and research biology- is not an easy path to take. But if you love what you are doing, it is totally worth it.

Giant Anteaters and So Much Joy

Ever since I learned about baby giant anteaters riding around on their moms' back, I've been obsessed with seeing one. Since I was out in the jungle in Nicaragua when this happened, I contented myself with imagining what it would look like. When I came back to the wonderful world of youtube, I immediately started watching videos. It was even better than I expected! I also discovered a video of a baby anteater from the Santa Ana Zoo, which is about an hour south of LA, or roughly between LA and Oceanside, where I live during the summer and my field season. I've been scheming to visit, calculating how old the baby is (they ride on the mom's back until they are about 10 months old) to make sure I could see some awesome animal stacking in action. Luckily, the little guy was born in November(ish), so I figured he would be about 8 months old in June. Plenty young to still get piggy back rides. Right?

Anteater "baby". Almost the same size as the adults, seemingly way too large to be carried.
We arrived at the zoo and made a beeline for the anteaters. When we got to their exhibit, I was so disappointed to see how big the baby was. He was practically the same size as his mom! They were each walking around on their own, and I thought for sure we had missed the opportunity to see them stack. They were still awesome, and I was still happy, though it wasn't "the greatest thing ever". 
After a lunch break and checking out some other animals we stopped by the anteaters again. Still both standing on their own, but now the baby was following mom around. They went out of sight for a few minutes, and we heard what sounded like a frustrated squeal. Was he trying to get a ride?! I waited with anticipation to see them return. And- OHMYGOODNESS!!! This ridiculous lumbering baby had convinced her to carry him around. And it was THE GREATEST THING EVER. 




(I was quite overcome with excitement. These photos were taken by Dave, who was a great sport and also enjoyed watching them for about an hour).

Channel Islands



The Central Coast of California is slowly becoming my go-to weekend travel destination, and one of my favorite places on earth. I can’t believe, as a native Californian, it has taken me this long to discover and appreciate this spectacular area, and all the incredible wildlife it has to offer! Dave and I drove up to Ventura and took the ferry over to Santa Cruz Island, which is part of the Channel Islands National Park. This is America’s least visited National Park, probably because it is quite pricey ($80 for the ferry! Yikes!) to get out there. About 20 miles off the coast, the ferry took an hour and we lucked out that it wasn’t too choppy because I am unfortunately prone to getting seasick. On our way out we passed a buoy with a GIANT Steller’s sea lion resting on it. This species is common up north- like Alaska north, and this is the very southern tip of its range. Apparently this individual hangs out on the buoy regularly, but it was a treat to get to see such an enormous fellow.


On the island there are no services- no cars, no bikes, just 25 campsites (which do have potable water and pit toilets! Luxurious!) and a handful of facilities for the rangers who live there.  The Channel Islands are home to an endangered species of fox found nowhere else- the Channel Island fox. Each island has its own unique subspecies, and I was really hoping to catch a glimpse of the Santa Cruz Island fox. I didn’t have to look far- these creatures have figured out that campers = food, and are like squirrels, running around campsites, jumping on picnic tables, and running away with any unattended food items. Heavy-duty lock boxes are provided at each picnic table, and when the foxes climbed on the table with us standing a few feet away during the middle of the day, we understood why.



The foxes are an endangered species success story. Descendants of mainland gray foxes, they have evolved on the islands for about 10,000 years with no natural predators and are quite small- the size of large house cats. Bald eagles have historically lived on the islands, though they only eat fish, seabirds, and carcasses; not live foxes.  Farming came to the islands, bringing with it DDT which began to wipe out bald eagles and non-native animals which were a food source for golden eagles, which could move in when their bald eagle competitors were declining. Golden eagles were also large enough that they easily preyed on the Island Foxes. By the late 1990’s there were only 80 foxes left on Santa Cruz Island. The National Park service and US Fish and Wildlife began an aggressive, multi-pronged approach to save the foxes.



Some of the remaining individuals were brought into a captive breeding program. The golden eagles were moved off the island and the native bald eagles were brought back in. Livestock were shipped off and the feral pigs were wiped out. Efforts continue to remove invasive plant species, such as fennel, which outcompete natives.  Foxes are now reproducing unassisted (as evidenced by the 3 baby foxes we saw! So cute!!) and are roaming the island. Of course, their interactions with campers (and human food) are not natural, but the park service makes sure to educate everyone who comes over on the ferry and make sure they are aware of the problem. It was amazing to see so many foxes!


Dave and I also went kayaking around the sea caves with Channel Island Outfitters, a great group that rents kayaks and organizes guided tours, which is what we did. Apparently the Channel Islands have the highest density of sea caves anywhere in the world! I certainly wouldn’t go into any of them without an expert who can judge the safety conditions- we got part way into one and backed out when our guide decided it was too sketchy to safely stay in. But it was amazing, going through arches and caves! There was one cave with a beach in the back they call Seal Beach, where harbor seals are often found resting. When we visited there were no animals on the beach, but two very curious young seals who swam right up and investigated us and our boats. They are so cute! We also so lots of sea lions, brown pelicans, and tons of cormorants. On the ferry back to the mainland we came across a pod of dolphins feeding on a huge school of bait fish- there were hundreds of dolphins around us, and they would come so close to the boat. What an incredible adventure, and so close to home!

A very Chilean reunion!

Tina and Morgan came to visit! You may remember them from pretty much every post from Chile, where we formed the Degu Crew. I've been lucky enough to see Tina every so often since she's out here in California too, and it was a super treat to have Morgan fly across the country so we could run around LA and eat everything imaginable in a weekend! We kept ourselves busy, but managed to finish the weekend with a big pasta dinner and some Chilean wine- just like in our apartment in Santiago!

A few highlights- and some of my favorite things around Los Angeles :)

We visited the LA Arboretum when everything was blooming!
Nom nom nom!
First Friday at the LA Museum of Natural History.  Dinosaurs, dioramas, and drinks. So good! 
Santa Monica beach and Bay Cities Deli. Plus sorbetto in a mango!
Soup dumplings from Din Tai Fun. Tina's eaten at the original location in Taiwan!

Hiking up to the Hollywood sign
Porto's Bakery. An overwhelming experience, but so ridiculously delicious!

My research- in a video!

I recently had to make a video about my research for a fellowship I received. Never having made a video before, it took me a lot longer than anticipated but I'm pretty happy with the way it came out. Hopefully it is fun to watch and also informative! I am about to start my field work again next week, so fingers crossed it all goes smoothly!


More camera trap photos!

Since camera traps were one of my favorite parts about Nicaragua, I wanted to share a few more awesome shots we got!

Birds!


February 19, 2013

This trip has been my introduction to the world of birding. It is an amazing place to start. There are so many birds here (the total count for Refugio Bartola since 2001 is over 400 species) and a lot of the birds are colorful and charismatic and happen to sit in the brush and trees that are easily observed from a hammock or the breakfast table. What makes it even better is that my fellow TA, JP, is an avid and knowledgeable birder. Since I spend most days walking around the forest with him, it has been an excellent introduction to the neotropical avifauna. My bird list is a 97 right now. With one day in the forest a couple days of travel, I’m hoping to hit 100 (which is crazy to me!).

Some of the most wonderful birds I have discovered follow ant swarms. First of all, ant swarms. It’s an amazing sight, the leaf litter writhes with ant bodies.  Army ants literally swarm the forest floor, attacking and eating any insect that can’t get out of the way fast enough. Flying insects and vertebrates can usually avoid the ants, but hop/fly up into the air as the ants come pouring through. This is where the ant birds come in- they follow ant swarms, catching and eating the insects that hop into the air to avoid the ants. The birds don’t eat the ants themselves, but the insects they scare up.

In addition to the unique behavior, many of the ant birds are absolutely striking with bright blue rings of skin around their eyes. Many of them are patterns of black and cinnamon color, and they make a soft chirring sound as they hop and flit through the understory following the swarms. One of these is a goofy looking bird that walks on the ground, looking a bit like a cross between a chicken and a short tailed peacock. This Rofous-vented Ground-cuckoo is apparently a must see for birders, and JP tells us there are neotropical birders where this is one of a few species they haven’t been able to find. I would have no idea of that here- I’ve been lucky enough to see two ground cuckoos in one location- one may have been a juvenile, it had a shorter tail and was less iridescent than the other- and I’ve had two separate sightings of these guys over a couple of days.

Rufous-vented ground-cuckoo!
Other birding highlights include watching a red-capped manakin lekking- tiny little birds with yellow legs and bright red caps, dancing like the moon walk on a thin branch (awesome youtube video of that here!). Also a rufous motmot, sitting on a low branch in the forest at dusk, a green ibis and a sunbittern near the river, and listening to a giant flock of mealy Amazon parrots coming in to roost in the evening, screeching and sounding like broken electronics up in the trees.

Some of my favorite creatures here in Nicaragua have been birds. I’m glad I finally gave them a chance!
