We are seeking two highly motivated and enthusiastic PhD students to study
sex chromosomes in birds and reptiles.

Deadline for applying: 9th January 2018

*Evolution and implications of sex determination diversity*

Lead supervisor: Dr Alison Wright, University of Sheffield

Co-supervisors: Prof Jon Slate (University of Sheffield), Prof Steve
Paterson (University of Liverpool)

Sex chromosomes have evolved independently, multiple times across animals
and closely related species often exhibit different sexual systems and
modes of sex determination. Understanding the causes and consequences of
this diversity is a major challenge in evolutionary biology, with important
implications for sexual selection, sexual dimorphism and adaptation.  The
project will tackle these questions using cutting-edge bioinformatic
techniques and next-generation sequence data across reptile species.
Reptiles are an ideal group to study sex chromosome evolution as they
exhibit an exceptional diversity in sex determination systems, where
different types of sex chromosomes have evolved independently multiple
times, making it possible to identify convergent evolutionary patterns.

The approach taken can be tailored to the particular interests of the
student, and could include studies of sex chromosome degeneration and
sexualisation, gene expression evolution and sexual conflict. Applicants
should have strong analytical skills and an enthusiasm for evolutionary
genomics.

Interested applicants are encouraged to contact Alison Wright before
applying (a.e.wright@sheffield.ac.uk <alison.e.wright@ucl.ac.uk>) for more
details on the project, funding and facilities. For details on current
research in the Wright lab, see http://secure-web.cisco.com/1us94BJ2psUwxbCoAu3Z1oVxUlKHBpR7MdCiSayKNG6nmX5NlrTEcsUxfp5yvKqK9zL7HCQYWINoI3lHp9yJf1-Ue-yLrgn-M_oAQ-6owURiIwOhd1R-jO6jIUna_7wKC6lAWaZZaI_928SUJhja2KP_w8GDS2o5yMXcu3PDOeuvS59jv_Zoyj7zbq_GVV6WgC7iqTMBwSEj1zvDwZ7Q-ku3I68vMILcnj04EFiqEbPXgoI8ptgtmVQWgn0slJw6zh3cwit3O9UmKMfDxCo6cqJc9BXowVG9heW38AKL8N5wxYYyOXKi_ScnE0R0hswS19LKYhMiPZeHL1xk6Q1hCC_VW_lcoB1xCnMwR_s1pq_Bgmim8eusUhUnk-LMQbCLQfZgj4K8e5KdF_RTnTQIgsj-OiDfGjQLU_qDRq5oj-nUW3JBpKcnUZ_FLGLgQk_8y/http%3A%2F%2Fwww.alisonewright.co.uk

*Evolutionary genomics of zebra finch **supergenes*

Lead supervisor: Prof Jon Slate, University of Sheffield

Co-supervisors: Dr Alison Wright (University of Sheffield), Prof Steve
Paterson (University of Liverpool)

Inversion polymorphisms (?supergenes?) are increasingly recognised as an
important source of genetic variation, responsible for some dramatic
phenotypes (e.g. social system in fire ants, male morphs in ruffs, mimicry
in butterflies etc.). We have recently shown that a supergene on the Z
chromosome (a sex chromosome) explains nearly all of the heritable
variation in sperm morphology in zebra finches (Kim et al. 2017; see also
https://goo.gl/cCUQHu).
However, the origin and evolution of the supergene are unknown.

This project will harness next-generation sequencing technology to
understand the Z chromosome supergene, and the evolutionary importance of
inversion polymorphisms more generally.  The student will use long reads
generated by 10X Genomics technology to:

1) Determine the origin of the Z chromosome inversion polymorphism;
2) Understand the molecular evolution of the genes within it;
3) Compare the Z inversion and at least three autosomal inversion
polymorphisms to understand how, and wherein the genome, inversion
polymorphisms arise.

The project will suit a candidate that is excited by analysing genomic
datasets to address evolutionary questions.

*Training*

These PhD projects will provide an excellent opportunity to learn
state-of-the-art
genomic skills to study sex chromosomes and test clear theoretical
predictions. The successful candidate will be trained in cutting-edge
bioinformatics and genomic techniques. The applicant will benefit from the
diverse range of expertise offered by the co-supervisors and researchers
within the Animal and Plant Sciences Department at the University of
Sheffield.

Ph.D. opportunities in the Karubian Lab

The Karubian Lab (http://karubian.tulane.edu) is seeking applications to begin Ph.D. studies in Fall 2018.

The Karubian lab is based at the Department of Ecology and Evolutionary Biology at Tulane University, in New Orleans LA. We have an accomplished group of students, and take pride in the supportive and diverse environment our lab and department provide. Students receive TA-ships that cover stipend and tuition costs during their time at Tulane, and several students have received competitive National Science Foundation Graduate Research Fellowships and other sources of external support.

The Karubian lab has a strong commitment to linking research to real world conservation outcomes via meaningful engagement with local communities in the areas where we work. Both these projects have important links to contemporary social issues, and incoming students are encouraged to participate in and contribute to these efforts. Please see http://karubian.tulane.edu/engagement/overview/ for more information.

The Karubian lab is committed to increasing diversity in STEM. Students from Latin America and other groups that are traditionally under-represented in ecology and evolution are particularly encouraged to apply.

Prospective applicants should contact Dr. Jordan Karubian (jk@tulane.edu) with a statement of interest and CV.

We are currently recruiting up to 3 students, for the following projects; please state which of the
project(s) you are applying to in your contact email:

(1) Evolutionary ecology and conservation of South American palms.

The over-arching goal of this project is to better understand the forces that regulate distributions and diversity of palms. This student will develop independent research that combines fieldwork on ecological processes in tropical rainforest (e.g., dispersal, competition, survival) with laboratory-based genetic approaches (e.g., population genetics / genomics, transcriptomics). Students will build upon previous and ongoing NSF-funded work that links behavior of dispersal agents to seed and pollen movement; characterizes ecological and genetic drivers of non-random seedling survival; and documents how naturally occurring environmental variation interacts with human activities to shape patterns of diversity. Please see http://karubian.tulane.edu/research/plant-animal-interactions/ for more information.

(2) Behavioral ecology and effects of lead exposure on Mockingbirds

This student will develop independent research in New Orleans to investigate how exposure to lead, a common contaminant in urban environments, impacts health and behavior of the northern mockingbird Mimus polyglottos. Our pilot work suggests that lead levels in mockingbird adults may be associated with increases in aggressive behavior. The student working on this project will characterize pathways of lead uptake; relate exposure to physiological condition, cognition, aggressive behavior and reproductive success; and explore the mechanistic (genomic and endocrine) underpinnings of these effects. Please see http://karubian.tulane.edu/research/gulf-coast-ecology/ for more information.

(3) Effects of habitat conversion on avian diversity and behavior.

This student will continue over a decade of work in a fragmented landscape in northwest Ecuador that examines the impacts of habitat change on avian diversity. The project will involve some combination of mist netting, analysis of satellite imagery, telemetry/tracking, and molecular analysis. Please seehttp://karubian.tulane.edu/research/conservation-biology/ for more information

Description
I am seeking a graduate student to develop a research project focused on Madagascar carnivores. The successful applicant will pursue an M.S.
degree in the Department of Natural Resources Science at the University of Rhode Island. The aim of the project will be to extend current knowledge of rainforest carnivores covering one or more of the following
