I am a MSc student at the University of New Brunswick (Fredericton, NB, Canada) studying the effects of interspecific competition on pollinator-mediated selection of floral traits. More specifically, my thesis project uses fireweed to look at how floral traits associated with attraction of pollinators (such as floral scent) can change when an unrelated, highly attractiveplant species is growing nearby. This project allows me to combine concepts and methods used in plant community ecology, plant-pollinator interactions, and floral evolutionary biology, with a dash of chemistry thrown in for good measure.
Before starting my masters in Dr. Amy Parachnowitsch’s lab (@EvoEcoAmy on twitter), I completed my BSc in Biology at Algoma University (Sault Ste. Marie, ON, Canada). While at Algoma University, I completed an honours thesis on co-occurrence patterns and temporal stability in an old-field plant community under the supervision of Dr. Brandon Schamp (who now co-supervises my masters project). Prior to my BSc, I completed a three-year diploma in biotechnology at St. Lawrence College (Kingston, ON, Canada).
I’m a first generation student and particularly passionate about improving learning and research experiences for undergraduates, as well as communicating science through art. This will be my second time hosting Biotweeps, (previously hosted as @moietymouse) and I’m looking forward to talking to you all again!
My name is Liz Franklin and I am an behavioural ecologist and entomologist. My passions are wide spreading but I generally come back to the behaviour of individuals and groups, particularly in the social insects (that’s ants bees and wasps). I studied ant behaviour for my PhD and now I study bumble bees again like in my undergraduate. I am originally from the UK but right now I am working at the University of Guelph in Canada as a post doctoral fellow working on a range of projects to understand how bumble bees use landscapes.
Next to doing science my next favourite thing is talking about it! I am a massive advocate of science communication and engage both in outreach for my work but also as a volunteer. Hopefully I can give some advice to those who are interested in this area.
Along with sci comms I hope to talk about the social insects, highlight some of the cool research going on out there, particularly in the realms of behaviour. I will give a shout out to bee diversity, test the waters of your bee knowledge and hopefully answer your burning social insect questions.
Look forward to speaking with you all!
Meaghan L. Pimsler is a Postdoctoral Fellow at the University of Alabama working with Dr. Jeff Lozier to integrate physiological, morphological, population genetic, and transcriptomic approaches to study the factors shaping adaptation in native pollinators. She earned her PhD from in the Department of Entomology at Texas A&M University, where she used de novo transcriptomics to investigate sexual dimorphism and behavioral ecology in an invasive blow fly with a unique and poorly understood sex determination mechanism. She received her BS in entomology from Cornell University in 2007, and subsequently spent three years in Okinawa, Japan working at two high schools as an English teacher.
After recuperating sufficiently from the rigors of her undergraduate education, she began her postgraduate journey with Dr. Jeffery K. Tomberlin and Dr. Aaron M. Tarone in 2010. Meaghan has had a deep and abiding love of arthropods her entire life, and determined at the age of four that she would be an entomologist. She helped found entomology clubs in both high school and college, and has helped organize many entomology themed outreach and enrichment events, including working with the Smithsonian Museum of Natural History on their BugFest, and with Cornell University’s Entomology Department on their Open House.
Meaghan is particularly experienced in the field of forensic entomology, and this has led to a certification in Crime Scene Investigation with Texas Engineering and Extension Services; teaching at workshops for federal, state, and local law enforcement groups; several national and international trips to give invited seminar talks; the opportunity to coordinate symposia at the 2013 and 2014 Entomological Society of America annual meetings as well as the 2016 International Congress of Entomology; and her election to Treasurer of the North American Forensic Entomology Association. Meaghan’s current passion, outside of her research, is science policy. After joining the organizing committee for the March for Science- Birmingham, AL, she was selected as an Entomological Society of America Science Policy Fellow in the Class of 2017. She looks forward to talking with you about entomology, bumble bees, bioinformatics, statistics, science policy, and anything else you might be interested in.
Hi everyone! My name is Kelsey Byers; I’m currently finishing up my first postdoc at the University of Zurich in Switzerland.
I grew up in the northeastern United States near Boston and did my undergraduate degree in biology; the program was focused on molecular and cellular biology. I decided after four years of that and a fifth year as a technician working on transcription factors that I wanted to shift to a more evolutionary focus, while maintaining molecular biology & genetics in my toolkit. I moved out west to Seattle for a PhD at the University of Washington in the Department of Biology in evolutionary genetics and speciation with my PhD advisors H.D. “Toby” Bradshaw, Jr. and Jeff Riffell.
In my PhD I worked with flowers in the genus Mimulus (the monkeyflowers, family Phrymaceae) and their pollinators. Two species of Mimulus, Mimulus lewisii and M. cardinalis, are in sympatry (grow together) in the western slopes of the Sierra Nevada mountains in California. Where they grow together, the main factor keeping them from hybridizing (the main reproductive isolation barrier) is pollinator choice – M. lewisii is pollinated by bumblebees, M. cardinalis by hummingbirds. I was able to show with some experiments with hawkmoths that Mimulus lewisii produces floral scent, even though we can’t smell it (humans have very poor noses, as it happens, despite our response to coffee!). It turns out that bumblebees respond very strongly to these weak scent compounds both neurologically and behaviorally. I was able to work out the genetic basis of the species’ differences in floral scent compounds, and using transgenic plants in the greenhouse, I demonstrated that if you remove the most critical compound from M. lewisii, its bumblebee pollinators are less likely to visit it.
In August of 2014 I moved to Switzerland to work with Florian Schiestl and Philipp Schlueter on two species of alpine orchids in the genus Gymnadenia that are native to the Alps. The two species are pretty closely related but look – and smell – really different! Here I’m working less with speciation and am looking more at adaptation, focusing on two main projects. First, I’m looking at species differences in selection (including pollinator-mediated selection) on a large variety of floral traits in the field. Second, I’m looking at the patterns of floral trait inheritance in hybrids in Gymnadenia – are they inherited as discrete ‘blocks’ of traits, or do hybrids align more closely to one parent or the other?
In the next few months I’ll be moving to the University of Cambridge to work on a postdoc with Chris Jiggins on speciation and reproductive isolation in Heliconius butterflies in Panama. Although it’s a bit of a departure from my previous focus on plant-pollinator interactions, the broader concepts of chemical ecology, speciation genetics, and insect olfaction are very much at the center of my research work, so I’m very excited!
Feel free to ask anything and everything! I’m excited to be here with Biotweeps!
Kelly Ksiazek (@GreenCityGal) is a fifth year PhD candidate and Presidential Fellow in Plant Biology and Conservation at Northwestern University and the Chicago Botanic Garden. She believes that the complexity and beauty of nature can be found all around us, including in our plentiful urban habitats. Biodiversity conservation could be better supported in cities if more was known about how communities respond to the harsh conditions of the so-called “concrete jungle.” She sees particular potential in the vegetated or green roof; a type of increasingly common habitat that incorporates a layer of growing media and plants into buildings. Her research looks at the possibility of using urban green roofs as habitat for native plant and pollinator conservation. Most of her experiments take place in and around her hometown of Chicago, IL USA where she is discovering how to incorporate various components of biodiversity into green roof designs that mimic local shortgrass prairies.
As a former high school science teacher, Kelly also enjoys finding opportunities to engage in science communication such as through her research blog (https://GreenRoofResearch.wordpress.com), a recently published activity book for children (www.greeningUPthecity.com) and various school and community presentations (for example, this week at the Laurie Garden in downtown Chicago: http://www.luriegarden.org/education-events).
When she’s not collecting data on green roofs, writing, analyzing data or performing experiments in the lab, she likes traveling to visit friends and discover new places, gardening with edible and native plants, exploring new restaurants and breweries in Chicago and experimenting in the kitchen.
I studied ecology at UEA, and after a series of short contracts, joined the Countryside Council for Wales (now Natural Resources Wales) in 1992. Since then, I have worked in Carmarthenshire, Meirionnydd and Swansea, mainly on Sites of Special Scientific Interest, their designation, management and monitoring, as well as liaising with landowners.
In 2011, I went part-time to start a PhD at Swansea University, studying hoverflies in grassland habitats (many of which are SSSIs) and their role as pollinators. This has involved field studies, as well as DNA barcoding of Welsh hoverfly species, and using metabarcoding to study pollen loads carried by hoverflies. I am jointly supervised by Dr Dan Forman and Dr Penny Neyland (Swansea University) and Dr Natasha De Vere (National Botanic Garden of Wales and Aberystwyth University) I aim to finish some time in 2016.
