2017 Conference Details

Dear Students!

We are delighted to announce that 3 TRAVEL GRANTS for graduate, Master’s, PhD, and postdoctoral students with outstanding contributions will be awarded to attend the 6th Conference of the International Society of Wildlife Endocrinology!

ISWE is pleased to sponsor two of these travel grants, one in memory of our dear friend and colleague, Coralie Munro. We are also very grateful for Arbor Assays’ generous sponsorship of the travel grant program.  Each travel grant will cover the costs of airfare and lodging up to a total of $1,000.

To apply, please complete the TRAVEL GRANT FORM that you can download here and send it, along with a copy of your approved abstract to: lara.metrione@sezarc.com

Please note:  You must still submit your abstract via the online submission system for general conference acceptance by February 20, 2017.  You will then send in a copy of your approved abstract with the travel grant application. Priority will be given to students that are current ISWE members. If you are selected to receive a travel grant, we will request a picture of you and a one paragraph biography to post on our website.


Notifications of awards will be given approximately by June 5th, 2017.


ISWE is a growing international society. For the 2017 Conference in Orlando, Florida we expect over 100 members to attend. A diverse array of members from North America and Europe with some attendees from Australia, Africa, Asia and South America will be in attendance. Members include academic and zoo-based scientists, students and fellows who focus on the discipline of endocrinology. Our members focus on welfare, reproduction and health monitoring using a variety of sample matrices including serum, saliva, feces, urine, fish scales, and feathers.

Dear Members...

Please keep in mind that some INTERNATIONAL TRAVELERS to the United States for the 6th Conference of the International Society of Wildlife Endocrinology must hold a valid VISA and a PASSPORT valid for at least six months longer than the intended visit!

If you do need a visa, please understand that the visa application process may take several months. An interview appointment is required for a visa application at all embassies and consulates. The wait time for this appointment varies, but may be as long as three months, with processing taking an additional month or more.  As soon as you decide to attend the meeting, please contact the nearest US Embassy or Consulate and begin the application process as soon as possible.

For official information on the visa application process, visit
Visa wait times for specific countries may be found at 
A listing of US Embassies and Consulates worldwide may be found at


If you need a letter of invitation/attendance for your visa application process, please let us know at mponzio@mater.fcm.unc.edu.ar

ISWE 2017 Conference Plenary Speakers

Nonlethal Approaches to Assess Shark and Ray Reproduction in the Field    From Silent Spring to Silent Night: 
A Tale of Toads and Men
Dr. Gelsleichter is an Associate Professor of Biology in the Department of Biology, University of North Florida. His research programs focuses on three major topics: the ecology of shark populations in northeast Florida waters, the reproductive biology and physiology of shark and their relatives and the effects of environmental pollutants on sharks and other fish species. These three research areas are highly interrelated and research is also integrated with the study of how hormones regulate various aspects of shark reproduction. Finally, his research also expands to the study of shark populations and other fish exposed to environmental pollutants such as mercury, industrial chemicals, and oil that are experiencing health effects that could impair their reproduction, survival, and overall population stability.

Dr. Tyrone B. Hayes is an American biologist, herpetologist and professor of Integrative Biology at the University of California, Berkeley. His research focuses on the role of steroid hormones in amphibian development including growth, metamorphosis, sex differentiation and hormonal regulation of aggressive behavior. He conducts both laboratory and field studies in the U.S. and Africa and currently, his research also examines the effects of exogenous steroids on gonadal differentiation and the potential role of endogenous steroids. His main goal is to understand how an animal translates changes in its external environment to internal changes, how these internal changes are coordinated, what molecular mechanisms are involved, and in turn, how changes at the molecular level affect an animal's ability to adapt to the changes in its external environment.


ISWE 2017 Conference Workshops

Pete Laver - Mandi Schook Meredith Bashaw - Janine Brown Rupert Palme - Kerry Fanson Edward Wilkerson - Rachel Santymire
This will be an interactive workshop designed to provide researchers an entry into quantitative analysis of hormone data using the R language and software platform. We will discuss various quantitative approaches specific to wildlife endocrinology as well as more general approaches to statistics. We will interactively step through some basic analysis of hormone data using R and RStudio, and briefly work together on topics such as: Descriptive statistics (including frequency distributions), power analysis and study design, frequentist statistics (parametric and non-parametric), Bayesian statistics, and information theoretic approaches. Participants should come away with a better understanding of the general approaches they can take, an improved quantitative vocabulary for discussing their data with a statistician, and the tools necessary for finding further information and help. All participants will be expected to bring their own laptops with relevant software pre-installed (instructions for this will be sent to participants in the weeks prior to the workshop). Proper validation of an assay is essential in order to gain meaningful insights from excreted glucocorticoid metabolite (GCM) data.  However, anyone who has conducted a validation study has likely been faced with challenging decisions about experimental design, assay selection, and data analysis. These challenges are exacerbated by the fact that many of us are dealing with sensitive species in zoos or in the wild.  Although there are many papers that discuss the importance of validation and some of the factors to consider, there are still several aspects of the validation process where questions abound.
The purpose of this workshop is to identify key questions and uncertainties about conducting validation studies, with a focus on the assay of GCM in urine and feces.  We will draw on case studies, published papers, and personal experience to understand how different methodological approaches can influence the outcome or interpretation of a validation.  Participants will be asked to identify and rank questions they have about validation studies with the aim of highlighting key knowledge gaps, from sample collection through to data analysis. This workshop is the first part of a long-term project to develop a set of well-researched guidelines, backed by empirical evidence, about the do’s and do not’s of validation studies.  We invite workshop participants to contribute to the long-term goals of this project.
The Wildlife Endocrinology Information Network (WEIN) is a web based, searchable data network containing information on the endocrine methods and analyses including sample type, sample processing, hormone assays and endocrine results on various domestic and wildlife species both in situ and ex situ. The database allows the sharing of information regarding endocrine monitoring in a given species and is a reference place for endocrinological techniques and species based information. The goal of WEIN is to become the primary resource for researchers worldwide to learn, analyze, and share information about the growing field of wildlife endocrinology. WEIN will provide a venue for techniques and data that are not publishable, creating a critical resource for people interested in zoo and wildlife health and conservation. In this workshop, you will be introduced to WEIN. We will take you step by step on how to search and extract information, entering and submitti or data to enter into WEIN and a laptop.
