“…The litter size (LS) of 12 eggs and relative clutch mass (RCM) 0.087 of Spilotes sulphureus in this study appear low compared to other large snake species: Chrionius bicarinatus (LS = 5-14; RCM = 0.55, N = 1), Chironius quadricarinatus (Boie, 1827) (LS = 6-7, RCM = 0.43, N = 2), and Spilotes pullatus (LS = 5-14, RCM = 0.31-0.48, N = 17) (Amaral 1929, Marques et al 2009, Pinto et al 2010, Marques et al 2014.…”

Reproductive behavior and development in Spilotes sulphureus (Serpentes: Colu bridae) from Ecuador. The Birdsnake Spilotes sulphureus is a large-sized species that occurs from the Amazon region to the Atlantic forest of South America. Despite the wide distribution little is known about its natural history. Here we report, for the first time, reproductive behavior displayed by this species observed in a pair of Ecuadorian specimens in captivity. A ritualized pre-copulatory behavior followed a colubrine pattern similar to the congeneric species Spilotes pullatus. The repertoire included chin-rubbing, continuous tongue flicking, head raising, body jerking, cloacal gaping, and partial mounting. Oviposition occurred 86-98 days after of the first copulation. Females lay clutches of 7-14 eggs. Juvenile coloration is remarkably different from adults. Newborns have a dorsum with transverse brown or gray bands, and white or pale gray interspaces; young of 1-2 years have green bands and yellow-green interspaces; adults have dark green bands. Ontogenetic color changes are presumably associated with antipredator strategies, change in size, vulnerability or habitat and microhabitat selection.Keywords: behavior, clutch, development, neonate, reproduction, ontogeny. ResumenComportamiento reproductivo y desarrollo en Spilotes sulphureus (Serpentes: Colubridae) de Ecuador. Spilotes sulphureus es una serpiente de gran tamaño que ocurren desde la región Amazónica hasta el bosques Atlántico de América del Sur. A pesar de su amplia distribución, poco se conoce sobre su historia natural. Nosotros reportamos por primera vez el comportamiento reproductivo presentado por especímenes de Ecuador en condiciones de cautiverio. Un ritual de comportamiento pre-copulatorio fue observado seguido por un modelo colúbrido similar a la especie congenérica como Spilotes pullatus. El repertorio incluye el roce mental, levantamiento de la cabeza, movimientos constantes de la lengua, sacudones del cuerpo, apertura cloacal y monta parcial. El parto ocurre entre 86-98 días después de la primera cópula. Las hembras ponen nidadas de entre 7-14 huevos. Individuos juveniles son notablemente diferentes a los adultos. Los neonatos tienen un dorso con bandas transversales café o grises e interespacios blancos o gris pálidos, individuos de 1-2 años tiene 114 Phyllomedusa -17(1), June 2018bandas verdes e interespacios verde-amarillentos, mientras que los adultos tienen bandas verde oscuras. Cambios ontogénicos están presumiblemente asociados con estrategias anti-depredadoras, cambio de tamaño, vulnerabilidad o selección de hábitats o microhábitats.Palabras clave: comportamiento, nidadas, desarrollo, neonatos, reproducción, ontogenia.

“…However, when the fishes were left on the water, the snake didn't show interest. The time of ingestion ranged between 40 and 45 s, considered fast as observed in other colubrids eating small prey (Marques et al 2014). We have succeeded in the feeding of Simophis rhinostoma with fishes in 64.5% of attempts (Table 1).…”

Poco se conoce sobre la biología de Simophis rhinostoma (Schlegel, 1837). No existe información substancial al respecto de su dieta, apenas que se alimenta de anuros y, en cautiverio, hay registros de la ingestión de lagartos. Presentamos el primer relato de la ingestión de peces por S. rhinostoma, un colúbrido que habita los dominios de la Mata Atlántica y Cerrado, así como algunos aspectos de su comportamiento exhibido durante la alimentación.

“…On both occasions, the individuals were on the ground, in a forest area. The diet is mainly composed of mammals (Marques et al 2014), but S.pullatus also feeds on lizards, birds and their eggs, and anurans (Martins and Oliveira 1998, Marques and Sazima 2004, Bernarde and Abe 2006). This species lays five to twelve eggs (Amaral 1930, Marques et al 2014).…”

Composition and natural history of the snakes from the Parque Estadual da Serra do Papagaio, southern Minas Gerais, Serra da Mantiqueira, Brazil

The Serra da Mantiqueira is one of the least inventoried physiographic areas of southeastern Brazil. There is great potential for detection of endemic species for which little or nothing is known about basic aspects of natural history. The Parque Estadual da Serra do Papagaio (PESP) within the Serra da Mantiqueira is an area of extreme biological importance because it houses mixed formations of grasslands, ombrophilous forests, and enclaves of Araucaria forests (mixed ombrophilous forest). Currently, the mixed ombrophilous forest covers less than 5% of its original range and areas occupied by this forest type, and associated ecosystems constitute refuges, housing several endemic, high altitude species. Between September 2015 and April 2016, field samplings were performed in the PESP using four distinct methods. The objective was to determine the composition and natural history of snakes from an isolated, high altitude area of the Serra da Mantiqueira. In PESP and surrounding areas, 80 individuals representing 24 species, 19 genera, and three families were recorded. Data are presented on abundance, habitat, daily activity, diet, reproduction, and defense. Comparison of the PESP snake assemblage with 30 other Atlantic Forest areas in southeastern Brazil indicate the Serra da Mantiqueira presents particular characteristics regarding snake composition.
