[ECOLOG-L] SUMMER NSF REU- how do predators alter parasite transmission

How predators alter parasite transmission in complex communities


The Johnson Laboratory (http://www.johnsonlaboraotry.com) is accepting a 
qualified undergraduate NSF REU applicant for our lab crew at the University of 
Colorado in Boulder beginning in May 11 (some flexibility) and concluding in 
early August 2019. 

The Johnson laboratory has made it our mission to sincerely commit to promoting 
diversity! This search is open to all student candidates (that will not 
graduate prior to June 2019) from any race, color, religion, ethnic, gender, 
gender identity or expression, sexual orientation, disability, age, or veteran 
status especially those from underrepresented groups in science. 

Research Project: Predator inhibition of trematode parasite transmission: The 
primary objective for this project is to have a student investigate a 
much-needed research topic surrounding the study of infections and pathology 
caused by trematodes. The selected student will lead an ambitious yet tractable 
study into how common aquatic predators affect the spread of parasites and 
whether these effects vary by parasite species or predator foraging strategy. 
Over the summer, the selected REU will work closely with Dr. Johnson and our 
research team at the University of Colorado Boulder. The student will gain 
valuable experience in designing experiments, quantifying ecological data, and 
statistical analysis. They will also obtain foundational knowledge of 
host-parasite interactions, predator-prey dynamics, and the identification of 
both parasite and free-living species. Following completion of the experiments, 
the student will work closely with the PI to analyze (1) how the rate of 
parasite consumption varies by predator, and (2) whether predators select 
certain parasites preferentially as a function of body size, movement patterns, 
or activity times based on the natural history of the parasite.  

To apply: Email an application package that should include (1) a brief 
statement of interest detailing how obtaining an REU would advance your career 
goals; (2) a description of related previous research; (3) a statement of how 
you will support diversity and inclusion in our laboratory, and finally (4) a 
current CV. Please compile the application package into a single PDF and email

[ECOLOG-L] Graduate Students in Community Ecology- Johnson Laboratory-Boulder Colorado

2018-07-17 Thread Dana Marie Calhoun
The Johnson Laboratory at the University of Colorado is in search of 
exceptional graduate students for start in 2019. The Johnson laboratory  
focuses on two pervasive and inter-related forms of biological change: 
disease emergence and species invasions. Both have important 
consequences not only for individuals and populations, but for entire 
ecological communities and ecosystem processes. Invasions and disease 
can also have costly economic and health repercussions for human 
society.  Our group strives to bring a broad perspective to these 
questions by combining field experiments, large-scale spatial and 
temporal field data, molecular tools and ecological modeling. Check out 
our website for recent publication and research areas 
http://www.johnsonlaboratory.com. Students will be directly involved in 
one of the two following projects:

1. Understanding the community ecology of disease: this project aims to 
understand how interactions among species within an aquatic community 
collectively influence pathogen transmission and disease risk. This can 
include interactions among hosts (dilution effect), among parasites 
(coinfection), and between non-hosts and parasites (predation). The 
selected student would have broad intellectual freedom to develop 
projects within this system but would be expected to conduct fieldwork 
in California (during summers). Preferred start date would be summer of 
2019.
 
2. How threatened species respond to drought, invasive species, and 
disease: using a compilation of data from California collected over 
nearly a decade, we are using multiple modeling approaches to better 
understand how to manage threatened species in the face of changing 
aquatic ecosystems. This newly funded work will combine large-scale 
analyses with collection of new empirical data, while also setting the 
stage for applied manipulations to promote conservation.

The Johnson Laboratory at the University of Colorado is in search of 
exceptional graduate students for start in 2019!

High-elevation aquatic ecosystems are among the most vulnerable to 
climate change and other forms of disturbance, yet few long-term records 
offer sufficient resolution to characterize shifts in ecosystem 
structure and their underlying mechanisms. We are part of the Niwot 
Ridge Long-Term Ecological Research program managed by the University of 
Colorado, which includes one of the longest-running sampling efforts of 
alpine aquatic systems. Students will be directly involved in the 
following project:

1. Global change and aquatic ecosystems: In collaboration with the Niwot 
Ridge Long Term Ecological Research (LTER) program, this project is 
focused on lakes and reservoirs along the Rocky Mountains of Colorado. 
Broadly, we are working to understand the short and long-term effects of 
climate change, nitrogen deposition and invasive species on biological 
interactions within these systems. The selected student would be 
expected to develop an MA or PhD-level project that help to advance the 
project’s overall goals.

How does spatial isolation interact with infectious disease to drive the 
population dynamics of endangered amphibians?

The Johnson Laboratory (http://www.johnsonlaboratory.com) is accepting a 
qualified undergraduate NSF REU applicant for our field crew in the Bay 
Area of California beginning in May 13-14 and concluding near the end of 
July to early August 2018. 

Project details:
This investigation will rely on the use of non-lethal swabbing methods 
(skin and buccal swabs) to obtain samples from two threatened amphibian 
species (California Red Legged frog, Rana draytonii, and the California 
Tiger Salamander, Ambystoma californiense) across the Bay Area of 
California that can be tested to assess population genetic structure and 
the presence of pathogens (e.g., Ranavirus and Batrachochytrium 
dendrobatidis). Such lines of inquiry will provide insights directly 
relevant to the conservation of these threatened species, particularly 
with respect to the degree of genetic mixing among populations, quantify 
degree of isolation across populations and the effects of population 
connectivity on infection patterns. The selected student will gain 
valuable experience in field sampling, swab collection, genetic 
techniques, and data analysis.

The primary responsibilities of the student will be to collect non-
lethal swabs from amphibian species while being a member of a larger 
team performing in-depth field sampling protocols. Field sampling will 
focus on amphibians, fish and invertebrates within California pond 
ecosystems. This will include performing additional field sampling 
techniques including but not limited to: dipnets, seines, visual 
surveys, snail parasite identification, and pathogen swabbing. In 
addition, this individual will be expected to assist with daily record 
keeping and equipment maintenance while staying at a University of 
California Reserve System field station located in the South Bay, Blue 
Oak Ranch Reserve ( http://blueoakranchreserve.net ). ONLY 
undergraduates that will be continuing their education in fall 2018 can
