Reptiles en corredores biológicos y mortalidad por atropellamiento vehicular en Barbas-Bremen, departamento del Quindío, Colombia

Abstract: ResumenLos corredores biológicos de Barbas-Bremen son una estrategia de conservación implementada en el departamento del Quindío, Colombia, con el objetivo de reestablecer la conectividad entre poblaciones bióticas presentes en los dos fragmentos de bosque más grandes de la región. No obstante, pocos estudios han evaluado la efectividad de estos corredores como hábitat para especies de fauna local y como facilitadores de dispersión de individuos entre las reservas naturales de Barbas-Bremen. En 18 salidas de c… Show more

“…Based on the regression tree analyses, we did not find patterns associated with ecological groups that would permit us to separate the species found on the highway from those found in the adjacent vegetation cover (Figure 7) or detect apparent patterns in terms of landscape window groups. These results are in contrast to reports from other studies of road-killed snakes in the Neotropics, where a greater incidence of road kills was reported for species that were diurnal, semi-arboreal, terrestrial, and with large body sizes (Hartmann, Hartmann, & Martins, 2011;L opez-Herrera et al, 2016;Maschio et al, 2016;Ramos & Meza-Joya, 2018;Sosa & Schalk, 2016). In Santa Cruz, Bolivia, Sosa and Schalk (2016) reported that terrestrial and semi-arboreal snake species experienced more road kills (71.6 and 8.2%, respectively), with fossorial and semiaquatic species being less affected (3.7%, 2.5%, and 0.4%, respectively).…”

“…having the most records (15.2%). The dominance of this genus in the road-killed assemblage is consistent with reports by Quintero-Angel et al (2012) andL opez-Herrera et al (2016) for the Andes region. The similarity of our results with previous studies may be due to the methods employed, as all three studies searched highways by walking transects, permitting the detection of species with small body masses and medium-sized mean body lengths, such as species in the genus Atractus (K€ ohler, 2003;Roze, 1996).…”

“…Se observó que los parques recreativos ecológicos ubicados a las periferias de la ciudad de Mérida albergaron un número de especies más elevado que los parques inmersos en la ciudad. Si bien es necesario realizar un muestreo más sistematizado para determinar el motivo de la diferente riqueza de especies entre los parques, es posible que la conectividad que tienen los parques periféricos con áreas verdes existentes a los alrededores de la ciudad beneficie la presencia de un mayor número de especies, en comparación con sitios inmersos en las urbes, que poseen una conectividad prácticamente nula ya que se encuentran rodeados por la mancha urbana (Illesca-Aparicio et al, 2016;López-Herrera et al, 2016). Así mismo, otro factor que puede ser de importancia es que los parques inmersos en la ciudad, por su cercanía y su infraestructura son los más frecuentados por los habitantes de Mérida, en comparación con los parques periféricos, lo cual puede influir en la riqueza de especies en estos sitios.…”
