Who we are

The Latin America and Caribbean Transport Working Group (LACTWG) was formed in 2019 with a membership consisting mainly of biologists, transport practitioners and specialists from lending institutions implementing solutions that decrease impacts of roads, railways, and canals on ecological connectivity.

With a primary focus on linear transport infrastructure, LACTWG devotes its expertise toward reducing wildlife mortality and making transport systems more permeable for animal movement throughout Latin America. Members also develop and apply cutting-edge science to improve human and wildlife safety by reducing conflicts and collisions.


Agustina Serrón


Agustina Serrón is a biologist and is part of the Research Line of Road Infrastructure Ecology and Biodiversity in Uruguay. She works with run-over prediction models and is currently doing a postgraduate, where she uses stable isotopes in the hair of run-over fauna, to find impacts generated by roads on their eating behavior.

Anthony P. Clevenger


Tony Clevenger is a wildlife research scientist at the Western Transportation Institute, Montana State University USA. His research the last 25 years has focused on developing science-based solutions to the increasing problem of expanding road systems and the conservation of landscapes and animal populations.

Clara Grilo


Clara Grilo is a researcher at CESAM in the University of Lisbon. Her research has focused on road ecology, mainly the effects of roads on the relative abundance, behavior, mortality risk and implications on genetic structure and population viability of birds and mammals worldwide.

Coral Pacheco


Coral Pacheco Professor-Researcher at the DACBiol at the Universidad Juárez Autónoma de Tabasco. Research on wetlands, Impact of infrastructures on wildlife, Road ecology especially on collision mortality, landscape-level effects, and the edge effect in protected areas.

Daniela Araya-Gamboa

Costa Rica

I work for Panthera in the Jaguar Corridor Initiative, in the conservation of the jaguar and the ecosystems it inhabits. I am the coordinator of the Wild cats Friendly Roads Project. We generate basic science for the implementation of measures that reduce the impact of roads on wild cats. We support the Government through the group Vías Amigables con la Vida Silvestre.

Diego Varela


I graduated as a biologist from the University of Buenos Aires. I work for CONICET at the Institute of Subtropical Biology (IBS) in Puerto Iguazú, coordinating the Atlantic Forest Biodiversity Observatory. I am the president of the local NGO CeIBA. I specialize in mammal ecology and conservation.  I have been working in Road Ecology for more than 10 years, promoting the creation and monitoring of mitigation measures (wildlife passages) in Argentina.

Esmeralda Arévalo-Huezo

Costa Rica

Biologist, works as an extension teacher at the Universidad Latina de Costa Rica, conducts research on road ecology with students from the biology school and has projects on conservation and infrastructure in conjunction with the VAVS group. She also belongs to the group Vías Amigables con la Vida Silvestre (VAVS) from where she has been able to support the government of Costa Rica in various issues of road management and conservation.

Esther Pomareda García

Costa Rica

She work as a regent biologist at the Las Pumas Rescue Center and Sanctuary; which is dedicated to the rescue and rehabilitation of wildlife, in some cases from being road hitted, and environmental education. In addition, she form part of the Group Vías Amigables con la Vida Silvestre Group, where it has supported the Government in various efforts at the country level.

Fernanda Zimmermann Teixeira


I am a biologist and postdoctoral researcher in the Graduate Program in Ecology / UFRGS, where I participate in research projects at the Road and Railroad Ecology Group. I investigate the impacts of roads and railways on wildlife, especially road mortality, and the effectiveness of mitigation measures.

Hugo Coitiño


Degree in Geography and Masters in Geosciences. Currently a PhD student in Geosciences. Ecosystem and Biodiversity management and conservation professional, with more than 12 years of experience. President of the NGO ECOBIO Uruguay and responsible for the Ecology of Road Infrastructure and Biodiversity research line. Currently working in the Biodiversity Division of the Ministry of Environment.

José Miguel Gabutti

Mexico City

José Miguel Gabutti is an environmental biologist, currently working in the Mexico program of the Wildlands Network organization in the Road Ecology section. His goal is to increase visibility and support for wildlife crossings in Mexico and throughout Latin America. Among his tastes is conservation and understanding how roads and paths affect the niche of the species.

Juan Carlos Bravo


Juan Carlos Bravo is the Mexico and Borderlands Program Director for the international conservation organization Wildlands Network. He promotes habitat conservation and connectivity in western Mexico and the United States with an emphasis on the border region known as the Sky Islands. He directs projects for the establishment of wildlife crossings along Highway 2 in Sonora, México.

Juan Carlos Jaramillo Fayad


Biologist from the National University of Colombia, PhD in Biodiversity and Conservation from the University of Santiago de Compostela, Master in Environmental Education. Research professor at the Metropolitan Technological Institute of Medellín, where he is the technical coordinator of the PECIV- Programa de Ecología de las Carreteras e Infraestructura Verde. He coordinates the Red Colombiana de Seguimiento de Fauna Atropellada -RECOSFA and directs several research projects, master’s thesis and doctorate in the area of Road Ecology.

Juan de Dios Valdez


Juan de Dios Valdez Professor-Researcher at the DACBiol at the Universidad Juárez Autonoma de Tabasco. Research on wetlands, Impact of infrastructures on wildlife, Road ecology especially on collision mortality, landscape-level effects, biological corridors, and the edge effect in protected areas.

Larissa O. Gonçalves


She is a researcher at NERF at Federal University of Rio Grande do Sul. She works on planning mitigation of the impact of wildlife roadkills on roads in southern Brazil. She organizes workshops to incorporate new analytical approaches into public policy instruments and teaches courses on assessing wildlife roadkill on roads and highways.

Mirna Manteca


Mirna Manteca is a biologist, currently working as Mexico Program Road Ecology Coordinator for Wildlands Network. She leads the road ecology projects in Sonora, working in research, management, and communications in conjunction with NGOs and government agencies in order to advocate for the establishment of appropriate mitigation structures.

Pablo Medrano-Vizcaíno


Pablo Medrano-Vizcaíno is a biologist, with a Masters in Conservation Biology. He is currently a PhD Researcher at the University of Reading (UK), where his studies focus on the analysis of traits and landscape metrics to predict wildlife mortality on Latin American roads. Additionally, he leads the Ecuadorian Network for the monitoring of roadkill, a citizen science project for the collection of roadkill of wildlife in Ecuador.

Víctor J Colino-Rabanal


Postdoctoral researcher at the University of Salamanca (Spain). Interested in the impact of linear infrastructures on biodiversity, particularly in spatial-temporal analyses of mortality patterns and the application of mitigation measures based on new technologies. Also in the development of green infrastructure strategies as an instrument of territorial planning to promote ecological connectivity and ecosystem services.
