Survivorship rates of adult Anolis mariarum (Squamata: Polychrotidae) in two populations with differing mean and asymptotic body sizes
Provedor de dados: 84
Autores: Bock,Brian C.; Zapata,Ana María; Páez,Vivian P.
We compared adult survivorships in two populations of the lizard Anolis mariarum with different mean and asymptotic body sizes to examine one prediction of age-specific mortality theory; that populations that experience higher adult mortality should exhibit earlier maturation and smaller adult body sizes. We used a maximum likelihood approach to evaluate different survivorship models and model-averaging to estimate survivorship and capture probabilities for each site and sex. Relative tail length did not affect survivorship rates of adults in these two populations, but body size was related to survivorship, with the largest individuals at the time of first capture having lower survivorship rates, so body size was included as a covariate in some of the...

DISTRIBUCIÓN POTENCIAL DE Podocnemis lewyana (REPTILIA:PODOCNEMIDIDAE) Y SU POSIBLE FLUCTUACIÓN BAJO ESCENARIOS DE CAMBIO CLIMÁTICO GLOBAL
Provedor de dados: 37
Autores: Ortíz-Yusty,Carlos; Restrepo,Adriana; Páez,Vivian P.
En este estudio se implementó el modelaje de distribución de especies para establecer el rango de distribución potencial de Podocnemis lewyana, explorar los componentes del clima que pueden influenciar dicha distribución y evaluar posibles fluctuaciones de su distribución bajo escenarios de clima futuro. Los modelos obtenidos predicen una distribución continua de sur a norte por todo el río Magdalena, desde los municipios de Rivera y Palermo en el departamento de Huila, hasta los departamentos de Atlántico y Magdalena en el norte. La temperatura fue el elemento del clima que más influyó en la distribución de P. lewyana; esta especie tiende a estar presente en climas cálidos y con poca variabilidad en la temperatura. El modelo de distribución transferido a...

Somatic growth rates of the Hawksbill Turtle, Eretmochelys imbricata, in Gorgona Natural National Park, Colombia, between 2004 and 2018
Provedor de dados: 50

ABSTRACT The Hawksbill Turtle, Eretmochelys imbricata, is globally assessed as Critically Endangered, and information in the Eastern Pacific Ocean is limited. For this reason, this investigation evaluated the somatic growth rates in an immature hawksbill sea turtle aggregation using capture-mark-recapture on the coral reefs at Playa Blanca and La Azufrada in the Gorgona Natural National Park, Colombia. Between 2004 and 2018, we made 89 captures of 49 hawksbill individuals. The mean curved carapace length (CCL) obtained was 41.6 cm (range 32-58 cm), and the mean straight-line carapace length (SCL) was 39.1 cm (range 30.0-54.1 cm), showing these reefs to be critical foraging grounds for immature individuals. The mean body condition index was 1.3 (range...
