“…It should be noted that in the Manso River we also recorded other species of snakes that inhabit well preserved habitats (e.g. Oxyrhopus occipitalis, Scaphiodontophis annulatus) (Rojas-Morales et al 2018). Currently, the information about the distribution of D. boshelli is still inconclusive, and it is possible that this species has a wider distribution along the Middle Magdalena River, encompassing the lowland and pre-montane humid forests of the Eastern and Central Cordilleras in Colombia.…”

Rediscovery of the enigmatic forest racer snake, Dendrophidion boshelli Dunn, 1944 (Serpentes, Colubridae): actions for the conservation of a critically endangered species Redescoberta da enigmática cobra florestal Dendrophidion boshelli Dunn, 1944 (Serpentes, Colubridae): ações para a conservação de uma espécie criticamente ameaçada Abstract Dendrophidion boshelli is a poorly known and endemic snake species from the Middle Magdalena river valley in Colombia. It was described in 1944 based on a single specimen from the municipality of Caparrapí, department of Cundinamarca. Since the original description, only three additional specimens have been established. As part of the results of a herpetological monitoring in the Miel I Hydroelectric project, department of Caldas-Colombia, three additional specimens of D. boshelli were found in 2014-2015. The specimens represent the second known population of the species. We presented morphological data and pholidosis; description of the coloration in life, and a description of the habitat. Resumo Dendrophidion boshelli é uma espécie de cobra endêmica e pouco conhecida do meio do vale do rio Magdalena, na Colômbia. Esta serpente foi descrita em 1944 com base em um único espécime do município de Caparrapí, departamento de Cundinamarca. Desde a sua descrição, apenas três indivíduos adicionais são conhecidos. Recentemente, como parte dos resultados de um monitoramento herpetológico no projeto hidrelétrico Miel I, próximo à localidade-tipo, foram encontrados três exemplares adicionais de D. boshelli. Os exemplares representam a segunda população conhecida da espécie. Dados morfológicos, a descrição de sua coloração na vida e uma descrição do habitat são apresentados. Recentemente, D. boshelli foi incluída no Livro Vermelho dos Répteis da Colômbia na categoria Perigo Crítico (CR), e também para a Lista Vermelha da IUCN. Por ese motivo, para promover a conservação local desta e de outras espécies endémicas e ameaçadas na área do projeto Miel I, sugerimos algumas ações no nível local, como estabelecer uma área de conservação com status legal no rio Manso, que é tributario do projeto hidreléctrico Miel I.

“…In contrast, this species is infrequently recorded in lowland humid and premontane forests of northern South America. The high diversity of amphibians (Díaz-Ayala and Zuluaga-Isaza 2015) and other small vertebrates (potential prey for C. grandisquamis) and the presence of well-preserved forested habitats and abundant permanent water sources in the study area (see Rojas-Morales et al 2018 would suggest that this is suitable habitat for the species. However, activity patterns and use of cryptic microhabitats in complex vegetative communities could easily result in the non-detection of many individuals, generating a bias in the observed abundance.…”

More than 40 species of snakes inhabit the humid forests of the Middle Magdalena River Basin of Colombia, yet studies on the basic aspects of snake ecology and natural history in this region are scarce. We searched for Ecuador Sipos (Chironius grandisquamis) during six years (2014–2019) of 6–24-day visual-encounter surveys by day and night in both rainy and dry periods. In 2,967 person-hours, we recorded 16 individuals, half during rainy and half during dry periods. Fourteen of the 16 encounters were in the evening and two in the morning. Snakes recorded during the day were foraging on the ground, whereas those recorded at night were inactive and perched in vegetation. Most inactive individuals had selected perches along streams flanked by riparian forests; ten were in shrubs and four in trees on branches 120–600 cm above the ground. We also record predation on a northern rainfrog (Craugastor metriosistus) on the forest floor during the day.

“…La familia Colubridae a pesar de ser la familia de reptiles más numerosa y de estar presente en diversos ecosistemas, es también un grupo menos estudiado (Rojas-Morales et al, 2018) a diferencia de los anfibios, esto podría deberse a que estas serpientes son más raras en los ecosistemas y para obtener buenos registros es necesario invertir mayor esfuerzo de muestreo.…”

Diversidad De Anfibios Y Reptiles en El Interfluvio Putumayo–napo–amazonas, Al Norte De La Amazonía Peruana

El conocimiento de la biodiversidad de anfibios y reptiles es fundamental para proponer la conservación de estos taxa. En este trabajo se realizaron registros por encuentros visuales y recopilación bibliográfica para conocer la diversidad de anfibios y reptiles por tipos de hábitats en el interfluvio Putumayo–Napo–Amazonas. Nuestros resultados muestran la existencia de 140 especies de anfibios y 108 reptiles. El bosque de colina tuvo mayor riqueza de especies (58 especies de anfibios y 40 de reptiles). Las familias con mayor riqueza fueron Hylidae (38 especies) y Colubridae (39 especies). El análisis de similitud de hábitats en anfibios mostró dos grupos: de los bosques de terraza alta, terraza media y bosque de colinas y del bosque de terraza baja, aguajal y varillal pantanoso. En los reptiles también se formaron dos grupos: de los de aguajal, bosque de colinas y terraza alta, y de los bosques de terraza baja, terraza media y varillal pantanoso. En este interfluvio, la herpetofauna está amenazada por la deforestación, la agricultura, la cacería de caimanes y recolección de huevos de tortugas. Si estas presiones ambientales se intensifican podrían causar drásticas reducciones poblacionales.
