In July 2013, I visited the Denver, Colorado, area to collect data from two collections housed at United States Geological Survey (USGS) facilities and the University of Colorado (CU) Museum of Natural History. The USGS collections are housed in the Core Research Center on the Denver Federal Center campus. The building is also a repository for a large collection of soil samples and approximately 1.7 million feet of drilled rock, sediment, and ice cores. The Museum of Natural History is … [Read more...] about Tracking down ammonites in the Denver, Colorado, area
Examining morphologic variation in varanid skulls through time and space
As a graduate student affiliated with the UCMP, there are many resources readily available to me. Not only does the museum have the largest university research collection, but the curators, museum scientists, and staff are some of the most knowledgeable and helpful anywhere. UCMP is recognized for taking care of its graduate students, and one of the ways they do it is by providing multiple funding opportunities. I applied to UCMP for funding last year in order to conduct museum travel for my … [Read more...] about Examining morphologic variation in varanid skulls through time and space
California pollen taphonomy and pollen trap study in Clear Lake, California
Pollen analysis (or palynology) has been used to study Quaternary changes in vegetation and climate in North America since the nineteenth century. Palynologists generally compare plant assemblages in spatial-time frames instead of focusing on particular plant species. These changes in plant assemblages across landscapes through time are a good indication of vegetation shifts caused by environmental changes. Besides using pollen assemblages to reconstruct parent plant communities in a particular … [Read more...] about California pollen taphonomy and pollen trap study in Clear Lake, California
The hunt for a Ph.D. thesis: Collecting Late Cretaceous plant fossils in New Mexico
"It ain't Mexico and it ain't new" [quoted from a postcard in a gift shop] Armed with hammers, chisels, pry-bars, boxes of newspaper, and sunscreen, two trusty assistants (recent graduate Meriel Melendrez and current undergrad Nicolas Locatelli) and I drove from Berkeley in our 4WD extra-long SUV heading for southern New Mexico. There, we met up with paleobotanist Dr. Gary Upchurch and crew from Texas State University and geologist Dr. Greg Mack from New Mexico State University for two weeks of … [Read more...] about The hunt for a Ph.D. thesis: Collecting Late Cretaceous plant fossils in New Mexico
Waterlogged wood on the seafloor and the critters that call it home
For a marine biologist, I spend a lot of time thinking about wood. What happens to it if it happens to wash into a stream? How much of it gets into the ocean? Where does it sink? What happens to it once it reaches the bottom? What animals are likely to make it their home? I’m far from the first to think about the role of wood in ocean systems. In fact, Darwin thought quite a bit about how plant material might make its way into the ocean and how long different kinds of wood might stay afloat … [Read more...] about Waterlogged wood on the seafloor and the critters that call it home
Grad student’s artwork graces journal cover
“There are great color reconstructions of dinosaurs, so why not a plant?” thought Department of Integrative Biology and UCMP grad student Jeff Benca when he set out to reconstruct the appearance of a 375-million-year-old Devonian plant. Using Adobe Illustrator CS6 software, he constructed a striking three-dimensional, full-color portrait of a stem of the lycopod Leclercqia scolopendra, or centipede clubmoss. This was no small feat, considering that the fossil plant Jeff was illustrating was a … [Read more...] about Grad student’s artwork graces journal cover
Werning co-authors paper on growth in Parasaurolophus
Recent Ph.D. grad Sarah Werning, now in a postdoctoral position at the State University of New York at Stony Brook, was a major contributor to a paper released today on ontogeny in Parasaurolophus, a Cretaceous hadrosaurid dinosaur notable for the hollow, bony tube on its skull. The study centers around a remarkable skeleton of a baby Parasaurolophus (nicknamed "Joe") discovered in 2009 by Kevin Terris, a student at The Webb Schools in Claremont, California, in exposures of the … [Read more...] about Werning co-authors paper on growth in Parasaurolophus
Marshall shows terrestrial mammal extinction due to Red Queen with new work published in Science
By studying 19 groups of Cenozoic mammals Charles Marshall and Tiago Quental tested and confirmed the Red Queen hypothesis. Red Queen is the hypothesis that states that groups must continue to adapt and evolve in response to their environments in order to survive. It's not just extinction events that threaten groups--it's also low rates of origination of new species. The new research (published in Science) shows that these mammal groups have experienced diversity declines in part due to their … [Read more...] about Marshall shows terrestrial mammal extinction due to Red Queen with new work published in Science
Warmer climates can lead to big lizards
Pat Holroyd and co-authors describe a new species of giant lizard in the latest issue of Proceedings of the Royal Society B. The fossil jaw bones of this lizard have been in the UCMP collection since the 1970s, but it took a while for them to be recognized as something special. The specimens are from an herbivorous lizard that lived in the warm climate of Asia 40 million years ago. Dubbed Barbaturex morrisoni, this lizard was much bigger than the largest herbivorous lizards alive today. The … [Read more...] about Warmer climates can lead to big lizards
Werning blogs at PLOS about the fossils of the Sierra Nevada
In her latest post over at the Public Library of Science blog The Integrative Paleontologists Sarah Werning writes about about what the fossil history of California can teach us about climate change. UCMP is teaming up with other Berkeley natural history museums on the Berkeley Initiative in Global Change Biology to strive for a comprehensive picture of the effects of climate change on past, present, and future life.

The Looy Lab paleo detectives: Dori and Cindy at the NMNH
Tuesday morning, February 12, 2013, Dori Contreras and Cindy Looy woke before dawn to catch a cross-country flight to Washington, DC, for a two-week visit to the Smithsonian’s National Museum of Natural History (NMNH). Originally, Cindy was going to attend a biannual workshop of the Evolution of Terrestrial Ecosystem Program. However, after Dori obtained a Sigma Xi grant to study a fossil leaf collection housed in the NMNH’s paleobotanical collections, they teamed up and turned it into a joint … [Read more...] about The Looy Lab paleo detectives: Dori and Cindy at the NMNH
The Looy Lab paleo detectives
Solving the mysteries of the past and present one rock at a time East of the Berkeley campus, we see the beautiful, green Berkeley Hills, the golden letter "C" and a somewhat classy-looking, dome-shaped building on the Lawrence Berkeley National Laboratory campus. This houses the ALS, or Advanced Light Source. Personally, I find the name a bit silly because it doesn't seem to capture the awesomeness of this giant machine. It's like calling the Space Shuttle a Progressive Flying Tool. The ALS … [Read more...] about The Looy Lab paleo detectives
Caldwell’s rare octopus research makes headlines

Plants have a lot to tell us about the past …
Jeff Benca is a welcome addition to the Department of Integrative Biology and UCMP’s highly active paleobotany group as a member of Cindy Looy’s lab. However, Jeff also spends a lot of his time “up the hill” at the UC Botanical Garden, where he has been given space for his astonishing collection of lycopods that he brought with him from his days at the University of Washington. This ancient vascular plant group (along with rare carnivorous plants and orchids) actually caught his interest while … [Read more...] about Plants have a lot to tell us about the past …
A collaborative grant to examine what triggers megafauna extinction
Tony Barnosky, with Charles Marshall as co_PI, has received an NSF grant that will support a highly collaborative research program to test the synergistic effects of climate change and human population growth in magnifying extinction intensity. South America offers a natural site to test these effects. Barnosky and graduate students Emily Lindsey and Natalia Villavicencio hypothesize that if human impacts were significant in causing extinctions, then the last records for taxa should be found … [Read more...] about A collaborative grant to examine what triggers megafauna extinction
Barnosky on Earth’s tipping points in Nature
Twenty-two scientists including lead author Tony Barnosky urge us to understand the danger of global environmental tipping points in their review paper in the June 7 issue of Nature. They examine data from past global environmental changes, compare it to how humans are changing the planet today, and discuss what that could mean for our future. They conclude that if we continue at our current rates of environmental destruction and resource use there will be dramatic impacts on the quality of life … [Read more...] about Barnosky on Earth’s tipping points in Nature

NeoMap: An important step toward answering macro-scale questions
In science we are often confined to studying processes that occur on local scales. This is a natural place to begin and there is great value in understanding local events and processes, but the ultimate goal, at least in my mind, is to synthesize all these smaller snapshots of how living things interact and respond to their environments into a cohesive, whole-world portrait. This kind of comprehensive understanding is particularly important in light of global climate change, which demands that … [Read more...] about NeoMap: An important step toward answering macro-scale questions
