Biomonitoring

Sea turtle biomonitoring - Yucatan Peninsula

Our project

Biomonitoring programs has become an indispensable tool for studying occupational and environmental exposure to chemicals, including emergent pollutants for ecological and human health surveillance. 

Somos un equipo de múltiples programas que colaboramos para conocer  causas de varamientos, mortalidad e impactos antropogénicas en tortugas marinas que migran y residen en la Península de Yucatán.

The generated information has important applications for environmental risk assessment studies, as well as regional and national reference for the development of mitigation strategies plans.

The biomonitoring project is currently being developed in Arrecifes de Puerto Morelos National Park-Punta Brava , Isla Contoy National Park, Wildlife Protected Area Xcacel-Xcacelito Sanctuary, Greater Caribbean Biosphere Reserve, Yum Balam Wildlife Protected Area, Biosphere Reserve of Sian ka'an, municipal beaches of Solidaridad and Mahahual, as well as the collaboration of federal authorities and programs for the conservation and protection of sea turtles in the State of Quintana Roo for the attention of strandings.

A finales de 2023 se dio inicio a las inspecciones y asesorías técnicas para la integración del Estado de Yucatán en la atención de varamientos, y se espera que para el año 2030 se establezca la integración global de la Península  de Yucatán (Campeche, Yucatán y Quintana Roo).

COMENTARIOS Y TESTIMONIALES

I had such an amazing experience during this externship! I was specifically collecting blood samples from loggerheads for my thesis on reproductive biomarkers. I have learned so many useful skills that will be so important for my future. I am beyond grateful for all that this opportunity has taught me! It has allowed me to grow so much both professionally and personally.

Mi estancia profesional con la Dra. Maribel fue una experiencia de mucho crecimiento profesional, pues tuve la oportunidad de aprender acerca de procedimientos médicos, necropsias, técnicas de muestreo en campo y técnicas de laboratorio en tortugas marinas. Creo que tener la oportunidad de realizar una estancia con una profesional tan preparada y con tanta experiencia como ella es algo único y a lo que se le puede sacar mucho provecho. El conocimiento teórico y práctico que adquirí considero que es y será esencial para mi futuro desarrollo profesional en esta rama de la medicina veterinaria en la cual deseo seguir formándome. Le agradezco a la AMVT y a la doctora por todo su apoyo y paciencia durante mi estancia y espero poder seguir aprendiendo y colaborando en futuras actividades con ellos.

Mi estancia profesional en el proyecto de “Biononitoreo de Tortugas Marinas en la Península de Yucatán” me ha permitido aprender sobre aspectos menos teóricos relacionados con el mundo de la investigación, como por ejemplo, como funcionan las oportunidades de doctorado y los procesos de publicación. Por otro lado, el trabajo de campo me ha dado una visión del contexto sociocultural de la conservación de tortugas marinas en México y las amenazas que enfrentan. En definitiva, ha sido una experiencia muy enriquecedora que me ha permitido resolver dudas sobre la orientación que quiero tomar en mi carrera profesional.

“Durante mi  estancia profesional con la Dra. Maribel Escobedo y la AMVT tuve muy buenas experiencias con el equipo de trabajo, además de obtener mucha información y paciencia por parte de la Dra. para explicarme temas acerca de tortugas marinas, campamentos tortugueros, playas y otras partes de la investigación. Esta estancia profesional me ha dado una visión mucho más amplia acerca del campo laboral de la Medicina Veterinaria en el área de mi interés: tortugas marinas. Hemos visitado múltiples lugares y zonas de monitoreo donde conocí personas que comparten mi pasión y están unidos por la misma causa, me hizo sentir que unidos somos más fuertes. Agradezco a la asociación por darme la oportunidad de formar parte de este proyecto tan bonito y también a las personas que me recibieron muy cálidamente, me siento afortunada por los lugares tan bonitos que conocí y lo que aprendí.”

Externship​

This program is designed to expose students to the work of a wildlife veterinarian in the sea turtle field. Based on their abilities and experience in the field, they will be assigned activities to develop during their stay, as well as receive training to perform these functions

The activities in which the students will participate are:

  1. Blood sampling of nesting turtles
  2. Hematology analysis at field
  3. Stranding response (field necropsies techniques, if its required)
  4. Sampling collection for pathology and toxicology research
  5. Nesting sea turtle patrol​
  6. Nesting beach clean-ups​
  7. Environmental education activities
  8. Workshops

*All of these activities will depend on the project and collaborating programs' agenda, events that occur during your stay (such as strandings), and weather conditions. Therefore, we cannot guarantee that all activities will take place during your stay.


Requirements

  1. Being a student in the last year of the degree (not having pending subjects) or a graduate (send proof of your obtain degree)

  2. Unofficial academic record (only students)

  3. Application form

  4. Cover letter

  5. Curriculum vitae (CV/Resume,  maximum 3 pages)

  6. Two recommendation letters

  7. Only applicants who submit all requested documents correctly will be considered, applications are accepted all year round.

*All documents must be sent in a single PDF document. Once the documents are reviewed, if your application is approved, a video call will be scheduled for an interview and to conclude your application process.

Work environment

This is a 2-4 weeks externship, where the environment is characterized by a high sense of community. Disrespect, racism, or discrimination are not allowed. We're a multidisciplinary and international team, so basic knowledge of other languages ​​is highly valued.

Field trips are made to nesting beaches and occasionally to feeding areas if environmental conditions allow.

Los sitios de muestreo corresponden a diversas playas de anidación a lo largo de los Estados de Yucatán (Marzo-Agosto) y Quintana Roo (Mayo - Julio), por lo que al momento de elegir una fecha de estancia se deberá tener esto en cuenta.

Physical demands

  • A high affinity to field work (beach, open sea, and jungle), tolerance to insects and adverse environmental conditions (e.g. storms, high thermal sensation, high environmental humidity) 
  • Tolerance to stay in rural environments and nature reserves where facilities are limited
  • Tolerance to unpleasant odors and blood
  • 80% of the activities are at night (20:00hrs a 5:00hrs)
  • Have an optimal physical condition to walk 5-10 km daily and climb occasionally
  • Be able to lift a minimum of 15kg
  • Have good color, peripheral and deep vision (the use of glasses is allowed).
  • Swimming (preferable)
  • Basic knowledge of first aid (preferable)
  • Teamwork and being self-sufficient

*The physical demands are representative of the activities that any member of the team must comply with, reasonable accommodations can be made so for people with disabilities can successfully perform essential functions.

**Activities carried out are similar to the physical work demands carried out in turtle camps, so having previous experience as a volunteer or field technician is highly valued.

Expenses

  • No accommodation, per diem or any kind of financing is offered, so the applicant must be able to cover all their expenses throughout their stay.
  • Tabulador de gastos $15,500  MXN ($757 USD) + vuelo

*This tabulator is an estimate of the monthly expenses (4 weeks), which includes accommodation, transfers and three meals a day. Expenses may vary according to the personal needs and preferences of each person. Support to find accommodation is offered to candidates who request it and/or who wish to share expenses with other team members. No recovery fee is requested, the externship is free of charge
