Presence of the snout beetle in Ecuador and potential invasion risk in South America.

snout beetles are a complex of at least eight cryptic species (Curculionidae: complex), native to mainland Australia and Tasmania, that defoliate trees and are considered important pests. Since the 19th century, three species of the complex have been introduced to other continents. Here, we document the presence of snout beetles in Ecuador.

Molecular phylogeny of Neotropical Parrot Snakes (Serpentes: Colubrinae: Leptophis) supports underestimated species richness.

Tetrapod taxa with broad geographic distributions across the Neotropics are often composed of multiple evolutionary lineages. In this paper, we present the most complete phylogeny of Leptophis to date and assess morphology-based species limits within the broadly distributed green parrot snake Leptophis ahaetulla sensu lato, which occurs from Mexico to Argentina. Although L.

Three new species of frogs of the genus (Anura, Strabomantidae) with a redefinition of the species group.

A new phylogeny for the species group is presented, its species content reviewed, and three new species described from the eastern slopes of the Ecuadorian Andes. Our phylogeny includes, for the first time, samples of , , and . The morphology of hyperdistal subarticular tubercles is also assessed among 21 species of .

[Prognostic role of NT-proBNP in emergency department in the elderly with acute heart failure].

Objective: To determine prognostic role of NT-proBNP as predictor of 30 day-mortality and readmission in the elderly with acute heart failure (AHF) treated in Spanish Emergency Departments (EDs), and to analyse the confounding factors when the NT-proBNP value is interpreted.

Material And Methods: A multicentre and multi-purpose cohort study with prospective follow-up was conducted on all patients aged 65 years or older with AHF treated in Spanish EDs. The variables recorded include demographic characteristics, comorbidity, details of episode, and NT-proBNP value.
