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.

Alberto González Gallina


Doctor of Science Alberto González Gallina, My career in Road Ecology started as a result of a Xalapa-Perote Highway Bypass to which we had to review several MIAs of different sections, in said project I was in charge of herpetofauna and mitigation measures (2009). Hence my master’s thesis was with Vertebrate Run Over in the Amozoc-Cantona-Perote road section (2011). In that same year I participated in the Workshop of the GIT Impact of Infrastructure on Wildlife in the framework of the SMBC, that was where I really entered Road Ecology, I have participated to date with this group both with oral presentations, as a moderator and organizer. I participated in the biological monitoring of the Nuevo Xcan-Playa del Carmen highway, where I had to locate, somehow design and monitor the construction of wildlife crossings, the first in Mexico that had wildlife crossings exprofeso both below the road as rope bridges for tree species (2013). I carried out my doctoral thesis with the monitoring of said fauna steps, focused on six species including the jaguar (2018). We participated in the proposed location of Fauna Steps on the Mayan Train in sections Palenque-El Bari, El Bari-Escárcega, Escárcega-Pustunich (2020). A proposal was made for the modification of wildlife crossings on the Trans-Isthmic Railway in Section 3.2 Chivelas-Laguna (2022). To date, two specialization works in Biological Sciences have been directed at the Universidad Veracruzana, the first of which was awarded as the best thesis in 2022 with the Ciencia Arte y Luz award from the same university. Five articles and two scientific notes have been published on the subject as the first author and I have participated in another four as co-author, five book chapters and four popular articles have been written and I have participated in a couple of journalistic notes.
