Dr. Joel Slade
Assistant Professor, California State University Fresno

Talk title: MHC and the genome: selection and population genetics vary between migratory and resident songbirds
Wednesday, January 3, 10:30-11:00 am in room 619/620 (6th floor)

Please describe your research for our SICB members.

The research I will present at SICB is from a combination of my postdoctoral research and my MS student (co-author), Esther Fernandez. This research adds to our understanding of the migratory exposure hypothesis since we found differences in haemosporidian lineages between migratory and resident dark-eyed juncos. Given migratory birds are hypothesized to have greater exposure to pathogens as they occupy more habitats than resident birds, there should be differences in the evolution and differentiation of certain immune genes like the major histocompatibility complex (MHC) class I and II. We also analyzed over 10,000 SNPs using ddRAD-seq to corroborate our results on the dark-eyed junco migratory and resident subspecies. Beyond this project, my research program at CSU-Fresno mainly focuses on analyzing the effect of urbanization on the evolution of immune genes and the genomes in cardueline finches. 

How do ‘omic help us understand immunity in wild animals?:

There are many useful aspects of using ‘omics to understand immunity in wild animals. Transcriptomics has allowed us to analyze the upregulation and downregulation of certain immune genes when exposed to pathogens. At the whole genome level, evolutionary biologists and ecoimmunologists better understand the evolution of gene copy numbers of the highly duplicated major histocompatibility complex in wild, jawed vertebrates – this is exciting for my research program. Finally, we cannot forget the pathogens and parasites, as affordable whole genome sequencing allows researchers to assess the evolution of virulence genes and antimicrobial resistance, which can help us mitigate disease outbreaks in wildlife and prevent zoonoses. 

Why is ecoimmunology an exciting field to research right now?

The relationship between the microbiome and disease susceptibility in wild animals. For birds, a captive environment causes individuals to lose unique microbial community assemblages, and instead, most individuals end up with similar microbiomes. This effect of captivity makes it difficult to detect a relationship between microbiomes and environmental factors. We need better approaches to understanding these relationships in the wild, including microbiome metagenomics. Beyond direct relationships between disease and the microbiome, we also need to incorporate background genetics from the host animal in uncovering these relationships. I look forward to the growth of this field. 

How did you get your start in studying ‘omics of immunity in wild animals? 

I started when we realized we could afford population genomics using ddRAD-seq. Reducing the genomic data in a species and comparing that to immunological parameters and disease susceptibility allows us to potentially target new candidate loci if a reference genome is available. 

What is your favorite thing about attending the annual SICB meeting? 

The collegiality, the student presentations, and the vast diversity of research topics presented.

What advice would you give to students attending the SICB meeting for the first time?

Do not be afraid to approach a PI and introduce yourself – we are human and are interested in your future career goals. Also, get to know people outside your university or lab – you can make amazing connections and even friends at SICB conferences. 

What are you looking forward to the most at SICB2024?

I am excited to see old friends and meet new people.

DEDE Welcomes New Officers – Q&A!

DEDE welcomes two new members of leadership as officers-elect!

Robin Warne

Dr. Robin Warne with trees in the background.
Dr. Robin Warne, Program Officer-Elect.

Professor of Biology at Southern Illinois University
DEDE Program Officer-Elect (2024-2025)
SICB member since 2005
First meeting: 2005

Please describe your research program for our SICB members:

My lab explores how animals physiologically mediate changing environmental conditions, and how these processes shape disease dynamics and ecological interactions. A recent focus of my research is the role gut microbiota play in host physiology, development, and susceptibility to disease. In amphibians, we explore how development, physiological performance, and disease are determined by gut microbiome interactions with host neuroendocrine function. We are also exploring the microbiomes and ecoimmunology of hibernating snakes. I also conduct field research aimed at linking animal physiology and homeostatic function to larger scale ecological dynamics. Most of this work is focused on desert rodent communities where we aim to test links between physiological function, gut microbiota, and immunity to environmental and nutrient dynamics across the ecological community.

What is your favorite thing about being a scientist?

I enjoy exploring knowledge and delving into the literature to bridge concepts and to develop innovative experiments. I also enjoy teaching and discussing these ideas with students and collaborators.

If early career researchers are thinking about a career in academia, what advice would you give them?

There are diverse pathways to working in science and if being a researcher and teacher is exciting to you then go for it. However, do your research (!?) into life as an academic so that you can be informed and realistic about the challenges and trade-offs you will likely encounter in your career pursuits.

What is your favorite thing about attending the annual SICB meeting?

All of the exciting integrative science!

What advice would you give to students attending the SICB meeting for the first time?

Have fun, and don’t worry if you find yourself overwhelmed because I often do as well!

Dr. Emily Le Sage, Secretary-Elect.

Emily Le Sage

Assistant Professor of Biology at Skidmore College
DEDE Secretary-Elect (2024-2025)
SICB member since 2015
First meeting: 2015

Please describe your research program for our SICB members:

I study how organisms respond physiologically to ecological change and how these responses shape infection and disease dynamics. My research program investigates the strong interdependencies of the neuroendocrine and immune systems of vertebrates to better understand disease ecology and evolution in a rapidly changing world. I address fundamental questions such as how are annual seasonal disease dynamics regulated by biological rhythms, and what are the causes and consequences of host heterogeneity? In two disease systems of interest, recent evidence suggests that some host populations are currently shifting from severe epizootic declines to enzootic recoveries. Thus, my lab capitalizes on this exceptional opportunity to understand underlying eco-evolutionary mechanisms of biological resilience to emerging infectious diseases.

What is your favorite thing about being a scientist?

Being a scientist shares some of the qualities of being a detective, in that I gather the pieces of a puzzle to tell a story. I love that feeling of clicking pieces together that create a picture of our natural world; and I love thinking about what’s missing and designing experiments that can click together enough puzzle pieces to offer us a glimpse into the mechanisms behind the magic surrounding us.

If early career researchers are thinking about a career in academia, what advice would you give them?

Don’t listen to those who portray academic life as their whole existence, that they have no other identity besides their publications, or that they’re a good scientist because they took a traditional route and never tried to deviate from that path. There’s no set path to being an academic, so don’t measure your worth using someone else’s ruler. It may take some time to get into a rhythm, but see that your work doesn’t eclipse your identity.

What is your favorite thing about attending the annual SICB meeting?

Seeing familiar faces and meeting new people, and of course learning new things

What advice would you give to students attending the SICB meeting for the first time?

You can’t see all of the talks, and that’s okay! It’s all about making connections and having new ideas or interests sparked by conversations.

What are you looking forward to the most at SICB2024?

I’ll be hosting my first symposium! I look forward to our round table discussions on biological resilience.

Part of the DEDE Best Student Poster Competition

Describe the research that you are presenting at SICB 2024:

Many bird species incorporate volatile plant material, such as pine needles, into their nests, which can correlate with reduced nest ectoparasite survival. My research investigated whether alpha pinene, the volatile compound in pine needles, directly affects parasite survival or indirectly through the host’s immune system.

What is your favorite parasite, pathogen, or immune molecule and why?

I love the parasitic mites that are found in our bird nests (Dermanyssus spp. and Ornythonyssus spp.) because they have the most beautiful shape and pattern when placed under a microscope!

What are you most looking forward to at SICB 2024?

I am very excited to meet other scientists and researchers and learn about the amazing research they are doing.

SICB 2024 Talk presentation: Friday, January 5, 11:30-11:45am in room 613/614 

Describe the research that you are presenting at SICB 2024:

I will be presenting on the use of environmental DNA metabarcoding to detect and classify amphibian assemblages in tropical and temperate regions. We sought to compare the effectiveness of these molecular methods to traditional amphibian visual encounter surveys in characterizing amphibian communities. We intend to use these findings to better understand how amphibian communities respond to the chytridiomycosis panzootic.

What is your favorite parasite, pathogen, or immune molecule and why?

My favorite parasites are echinostomes, which are a type of trematode parasite. These parasites have complex multi-species, multi-host life cycles, and I worked with them in my undergraduate studies so they hold a special place in my heart. We would collect them from snails, their first intermediate host, and experimentally infect tadpoles, their second intermediate host. It is always interesting to see the echinostomes at various life stages, from the free-swimming cercariae stage after emerging from the snails, to encystments within the tadpoles kidneys that look like perfect circles.

What are you most looking forward to at SICB 2024?

I am most looking forward to experiencing the hustle and bustle that is characteristic of larger conferences! I have only ever attended in-person conferences that are smaller in scale, so I am excited to be surrounded by so many enthusiastic scientists from all different fields at SICB 2024. I look forward to presenting my own research at SICB in-person this time around too.

Describe the research that you are presenting at SICB 2024:

The high prevalence, life-long persistence, and absence of major health consequences of Babesia microti infection characterize the potential role of the common yellowthroat as a reservoir for the tick-borne pathogen, Babesia microti.

What is your favorite parasite, pathogen, or immune molecule and why?

My favorite immune molecule is interferon. It’s an often overlooked cytokine that possesses not only antiviral functions but also plays a crucial role in mediating inflammation.

What are you most looking forward to at SICB 2024?

Conversations with folks in the field!

SICB 2024 Talk presentation: Friday, January 5, 3:15-3:30pm in room 603

Describe the research that you are presenting at SICB 2024:

I will be presenting on a rapid, inexpensive, and field-deployable method for the molecular detection of Batrachochytrium dendrobatidis – the causative agent of amphibian chytridiomycosis. This CRISPR-based approach – termed FINDeM – uses non-technical tools and body-heat inducible reactions for species detection, thus providing individuals without formal molecular biology training an opportunity to harness the sensitivity of DNA-based techniques. Finally, this approach can be easily modified for the detection of other taxa, suggesting that FINDeM and other similar CRISPR-based systems may revolutionize how we detect organisms moving forward. 

What is your favorite parasite, pathogen, or immune molecule and why?

Bacteriophage. Their relationship with bacteria represents one of the longest evolutionary arms-races and has granted us not only a better understanding of host-pathogen interactions but also important tools for molecular biology research. 

What are you most looking forward to at SICB 2024?

Describe the research that you are presenting at SICB 2024:

I’ve looked into how the bone armor development of threespine stickleback changes from freshwater to saltwater environments. At SICB I’ll be answering the question: What happens to the bone density and shape of stickleback armor as these fish adapt to either high or low calcium environments?

What is your favorite parasite, pathogen, or immune molecule and why?

It’s got to be the tongue-eating louse (Cymothoa exigua)! This little arthropod infects it’s fish host and removes the fish’s tongue. It then attaches itself to where the tongue used to be and effectively becomes the fish’s new tongue! I always thought it was hilarious to see the little fish swimming around with a little guy in it’s mouth. 

What are you most looking forward to at SICB 2024?

I’m looking forward to connecting with new people, learning about what they are passionate about, and getting inspired!
