ERUDITUS bark beetle identification training app

Posted on June 19, 2023 by jirihulcr in Announcements
ERUDITUS bark beetle identification training app

Need to train your bark beetle identification skills? Do you want to skip character-based keys and practice your “gestalt” (identification by the overall morphology using your expertise)? Try the new app ERUDITUS, available for download on your smartphone from Apple Store and Google Play.

It is not an Artificial Intelligence-based app for beetle identification magic. It trains YOU! Your human intelligence :). The Entomology Today newsletter describes it here: https://entomologytoday.org/2020/10/07/bark-beetle-identification-app-for-that-eruditus/

New Geosmithia review

Discovered relatively recently, these bark beetle-associated fungi are ubiquitous in the scolytine realm. But not where the Ophiostomatoid fungi reign. https://link.springer.com/article/10.1007/s11557-023-01880-x

PhD in quantitative biology focused on bark beetles

Posted on August 17, 2022 by jirihulcr in Announcements
PhD in quantitative biology focused on bark beetles

Join the Forest Entomology team at the University of Florida (www.ambrosiasymbiosis.org) on our quest to understand forest insects and their evolution, ecology and systematics using cutting-edge biology methods.

This position can be focused on several topics:

  • systematics and phylogenetics
  • artificial intelligence (machine learning) in beetle identification
  • genetics, genomics or transcriptomics of the beetles
  • biodiversity information management

We appreciate previous experience with some of these fields, but it is not required. What we value the most is a commitment to rigorous science, love for numbers and data, good writing skills, and some biology nerdiness.

Dates

  • Applications are due on February 20, 2022.
  • Start: ideally in the Fall 2023.

Salary

The fully-funded PhD student position includes a $30,000 annual stipend, University of Florida tuition, health insurance, and research expenses (the total value of this position is over $200,000). Opportunities for international travel, conference visits and collaborations will be regularly available. International students are encouraged to apply.

Location

The main campus of the University of Florida in Gainesville, FL. Gainesville is one of the best college towns in the U.S.

How to apply

Email 1) your CV, 2) a short statement of interest and 3) a list of your hobbies to hulcr@ufl.edu with subject line “Beetle data science 2023”.

POSTDOC: Ambrosia symbiosis transcriptome

Posted on August 12, 2022 by jirihulcr in Announcements
POSTDOC: Ambrosia symbiosis transcriptome

The University of Florida Forest Entomology Lab is offering a postdoc position to study the molecular interactions between the insect tissue and the fungus in the ambrosia symbiosis.

We have the data; we need you to analyze them!

We have several transcriptome sequence datasets for the different tissues (fungus-free beetle, pure fungus, and the mycangium where the two unite) and we need a smart molecular biologist or bioinformatician to interpret what makes the two organisms talk. We also have a genome sequence of the beetle.

Previous experience with transcriptomics, insect of fungus molecular physiology, or other fields of bioinformatics and molecular biology will obviously be a bonus. Independent publication experience is required (the output of the project is not just the analysis, but a paper). Innovative interdisciplinary ideas about symbiosis functioning are welcome.

The position includes annual stipend of $60,000 and health insurance. The initial contract is for one year with high likelihood of extension to multiple years depending on productivity. The position is based at the University of Florida, Gainesville, FL. Partial remote work is acceptable, but is not a complete home office; we do need the postdoc to appear in the lab at least sometimes. International applicants are welcome.

NEW Application deadline: September 15, 2022.

Start date: ideally in the fall of 2022 or early 2023.

To apply

Send an email to hulcr@ufl.edu and include 1) Cover Letter, 2) your CV, and 3) a list of hobbies and interests.

Beetle-fungus postdoc

Beetle-fungus postdoc

The University of Florida Forest Entomology Lab is offering a postdoc position to study various aspects of the bark beetle-fungus symbiosis and its effect on trees.

The topic is open-ended

The applicant will decide, together with our team, the topic they will pursue. It should be related to the relationship between bark/ambrosia beetles and fungi, ideally using molecular biology or quantitative/statistical methods. Previous experience with molecular biology or statistical ecology experience would be a bonus.

Topics that we are seeking to develop include:

  • DNA or RNA metabarcoding of fungal communities
  • the transcriptome of the mycangium
  • genome features in the beetles and/or the fungi related to the symbiosis
  • fungus community analysis, network analysis or modeling
  • physiology of trees under attack
  • pest and disease diagnostic tools
  • invasive beetle/fungus assessment
  • forest pests in Asia
  • policy and regulation of threats to forest health

Other topics are available, and we welcome the candidate’s personal research preferences.

Includes annual stipend of $50,000 and health insurance. The initial contract is for one year with high likelihood of extension to multiple years depending on productivity. The position is based at the University of Florida, Gainesville, FL, but can include cooperation with colleagues at other institutions. International applicants are welcome.

Application deadline: Until filled.

Start date: any time during 2021 or early 2022.

To apply

Send an email to hulcr@ufl.edu and include 1) Cover Letter, 2) your CV, and 3) a list of hobbies and interests. Specify which of the two positions you are interested in.

POSTDOC or PhD: invasive wood borers

POSTDOC or PhD: invasive wood borers

Interested in invasive species and international field work? Join our team in an exciting project:

Pre-invasion assessment of Asian wood borers by sentinel gardens

We are looking for a PhD STUDENT or a POSTDOC to manage existing sentinel gardens in China and to collect unique data on high-priority, potentially invasive wood boring insects. What is a sentinel garden? See the coverage of our project in Science: Scientists plant ‘sentinel trees’ to warn of devastating pests.

Our first round of results is very promising, see the video below:

The position is fully-funded, and includes annual stipend ($26,000 for a student, $50,000 for a postdoc), health insurance, research expenses, and visa assistance.

The PhD graduate assistant contract is for 4 years. Postdoc contract is for one year with high likelihood of extension to multiple years depending on productivity. The positions are based at the University of Florida, Gainesville, FL, but will include substantial field work in Asia, most likely China. Opportunities in cutting-edge research technology, conferences and collaborations are regularly available. International applicants are welcome.

Colleagues from China are welcome to apply for this position. We completely understand the difficulties with current visa policy and travel. If you are interested in working with us but are concerned about your ability to join an American institution, let’s get in touch to start the conversation.

The project will focus on one main research direction:

  • Interactions between Asian wood borers and American trees in our network of sentinel gardens in China.

Additional topics that the applicant is welcome to develop include:

  • Beetle or fungus molecular and traditional systematics or ecology.
  • Host tree physiology and response under stress.
  • Translation of invasion science to policy, collaboration with agencies.

Previous experience with beetle research is not necessary. Experience with invasion ecology, systematics, tree physiology or statistics is a bonus.

Application deadline

March 12, 2021.

Start date

Any time during 2021, the earlier the better.

To apply or to inquire, send an email to hulcr@ufl.edu and include 1) Cover Letter, 2) your CV, and 3) a list of your interests and hobbies.

There is not one, but many ambrosia symbioses

Posted on April 23, 2020 by jirihulcr in Announcements
There is not one, but many ambrosia symbioses

Each ambrosia fungus is different beetle food, not convergent! See our latest article in ISME: https://www.nature.com/articles/s41396-020-0593-7

To me, the most important take-home message from that work is that, with a robust hypothesis and experimental design, even negative results are super informative.
