January 2017 - Hanna and Jason once again headed to Staniel Cay (Bahamas) to meet up with members of the Barrett and Pringle Labs for some fieldwork. This time the focus was on sampling green anoles on the experimental islands for morphological and genetic analyses. The weather was not anole-friendly...very windy and a bit on the cool side for our lizard chums. Given the conditions we did a great job, catching and phenotyping nearly 100 green anoles and catching nearly 200 brown anoles for Oriol's behavior experiment. Well done everyone!
January 2017 - A friendly jester welcomed Sozos, Chris, and Zac to New Orleans for the 2017 Society for Integrative and Comparative Biology (SICB) meeting in early January. They all gave great talks on completed and on-going research. Sozos presented results from his PhD research on colonization history, genetic diversity and fitness of non-native wall lizards (Podarcis muralis) in England. A member of the audience liked the talk enough to tweet about it! Chris talked about the impacts of urbanization on morphology, thermal preference and parasitism on two non-native Anolis species in Miami, A. cristatellus and A. sagrei. Read a review published on Anole Annals. Zac presented results from his PhD dissertation on factors that determine brown anole body size across an urbanized landscape and in relation to natural populations. Read a review published on Anole Annals. They also attended some live jazz and blues performances in bars and restaurants at night.
December 2016 - Congratulations to undergraduate Jess Atutubo for her 2nd place poster at the annual Coastal Fellows Symposium at the University of Rhode Island. Her project tested whether roads influence the population genetic structure of eastern painted turtles across the state of Rhode Island. Jess worked with Ph.D. students Scott Buchanan from the Karraker Lab and our very own Hanna Wegener.
December 2016 - The 2016 "Lizards on the Loose" Fairchild Challenge videos are starting to pour in on Youtube (click here for a selection of videos). As part of this year's Challenge, middle school students from South Florida schools communicated the results of their lizard surveys and their experiences by producing a video. They did a great job with their videos! Here's a nice article about our project from FIU News and more information about the Fairchild Challenge science education program sponsored by Fairchild Tropical Botanic Garden.
October 2016 - You might think Oriol has the look of a scientist concerned about whether or not Hurricane Matthew has disrupted his selection experiment...good news! Oriol and Jason were in Abaco, Bahamas this month and they are happy to report the experiment continues. Some signs of the hurricane were apparent - damaged vegetation on the southeast side of the islands, some seaweed in the vegetation, a high rack line due to the storm surge, and a couple of unexpected lizard visitors. We had a very productive trip and a blast kayaking between the study islands. Our stay at the the Friends of the Environment's new Kenyon Research Centre was fantastic. Thanks for the hospitality!
September 2016 - Andrew, Chris, Sozos and Jason were in Miami for an early fall field trip. The primary purpose of the trip was to recapture lizards marked over the summer for a selection experiment. New lab postdoc Sozos caught his first anole and was an expert by the end of the trip. Highlights included an observation of a non-native Cuban Knight Anole (Anolis equestris), on the left below, consuming a non-native Tropical House Gecko (Hemidactylus mabouia). Andrew and Chris found this Green Anole checking himself out in the side mirror of this police cruiser.
July 2016 - Hanna presented part of her Ph.D. dissertation research at the Herpetology meeting in New Orleans. She found evidence for hybridization between native green anoles (Anolis carolinensis) and introduced Cuban green anoles (Anolis porcatus) in the Miami area. Check out Anole Annals for more information.
February 2016 - Here are some of the winning posters from our 2015-16 "Lizards on the Loose" Fairchild Challenge. Middle school students from 38 Miami area schools produced 65 research posters explaining the results of their lizard surveys. Click (here) for more information on the fantastic Fairchild Challenge science education program sponsored by Fairchild Tropical Botanic Garden.
January 2016 - Hanna, Oriol, and Jason were in Staniel Cay (Exumas, Bahamas) over winter break doing fieldwork with colleagues from Rob Pringle and Rowan Barrett's Labs. We caught hundreds of brown anoles from experimental islands for morphological and genetic studies. We also worked with Nate Dappen and Neil Losin from Day's Edge Productions to shoot video and interviews for their forthcoming Anolis lizard film series.
October 2015 - Jason and Peter Paton from the Department of Natural Resources Science at URI gave keynote addresses at the International Seminar on Biological Sciences hosted by the Universitas Sumatra Utara in Medan, Indonesia. Highlights included seeing Sumatran orangutans near Bukit Lawang and visiting Lake Toba, which occupies the caldera of a supervolcano that erupted ~70,000 years ago. Many thanks to our hosts It Jamilah, Alex Barus, and the wonderful students from USU.
Summer 2015 - Jason, Zac, Kevin, Andrew, and Oriol had a successful field campaign in Miami. Oriol and Zac's project on the effects of invasive predators and urbanization on variation in behavior and personalities of brown anoles is now out in Global Change Biology.
April 2015 - Kevin successfully defended his M.S. thesis. Congratulations! His research investigated how structural habitats altered by urbanization influence escape behavior of anoles and he conducted field research in San Juan, PR and Miami, FL. Good luck with your Ph.D. program at the University of Massachusetts Boston.
Spring 2015 - Congratulations to Ph.D. student Andrew Battles on winning a prestigious National Science Foundation Graduate Research Fellowship. Way to go Andrew! He is studying the ecological and evolutionary responses of anoles to urbanization. Andrew is seen here contemplating the urban landscape in Coral Gables, FL.
Summer 2014 - Check out these great anole videos and online labs featuring our research in the Bahamas produced by the Howard Hughes Medical Institute for their BioInteractive program. For the "Lizards in an Evolutionary Tree" video (click here). For the "Look Who's Coming to Dinner: Selection by Predation" video (click here). For the "Lizard Evolution Virtual Lab" (click here). Have fun!
April 2014 - Jhoset successfully defended his M.S. thesis. Congratulations! His research focused on the effects of invasive Green Iguanas on seed germination and seed dispersal in a Puerto Rican mangrove forest. Now published in Biological Invasions. Jhoset is in law school continuing his pursuit of the gentleman-scholar ecomorph.
Summer 2013 - Haley's summer research focused on the short-term effects of artificial night lighting on behavior and performance of anoles, primarily in the Brown Anole (Anolis sagrei). Observations of normally diurnal anoles foraging under artificial lighting at night prompted previous researchers to describe a "night-light niche" for anoles. However, little research exists beyond isolated observations of lizards foraging under lights at night. Haley conducted a two-month experiment at the Montgomery Botanical Center in Coral Gables, Florida. During the first month, she collected pre-treatment data on anole habitat use and behavior during both the day and night. The second month began with the application of the night-light treatment (incandescent floodlights) and she continued to monitor habitat use and behavior as well as several measures of lizard performance. City lighting is dramatic example of human-mediated global change and we are only beginning to understand the consequences for some animals.
Summer 2013 - Jhoset spent the summer investigating the effects of invasive green iguanas (Iguana iguana) on mangrove plant communities and commercial plants at the Humacao Natural Reserve in northeast Puerto Rico. He collected and classified seeds from the reserve, and also collected scat from the field and from captive green iguanas feed Papaya (Carica papaya), which is an important crop at many Caribbean Islands. Approximately 1,200 seeds from both the Humacao Natural Reserve and captive green iguanas were planted and germinated under greenhouse conditions. Impacts of the green iguana invasion in Puerto Rico are debatable among scientists. Quantifying their effects on seed germination may reveal important interactions with local plant communities and help to clarify conservation and mitigation efforts of this species.
August 2012 - Jason and Tobias Uller (University of Oxford) organized a symposium at the 7th World Congress of Herpetology in Vancouver, Canada entitled "Insights from Invasions: Using Exotic Amphibians and Reptiles to Study Ecological and Evolutionary Processes." Featured talks included Rick Shine's (University of Sydney) work on invasive cane toads in Australia and Brad Shaffer's (UCLA) studies of hybridization between invasive and native tiger salamanders in California.
July 2012 - Check out our recent paper on the evolution of thermal tolerance during the introduction of Anolis cristatellus to Miami, FL. [PDF] Co-author Neil Losin's photo made the cover! See more great photos and videos from Neil and Nate Dappen at Day's Edge Productions.
June 2012 - Our lizard room at URI is operational and just in time for the arrival of over one hundred Anolis cristatellus from Miami and Puerto RIco. The first little guys hatched in late June and are doing well.
March 2012 - Our experiment with brown anoles in the Bahamas showing an interaction between founder effects and adaptive differentiation in determining phenotypic values received some nice media coverage.
