Rediscovery of Hyalinobatrachium chirripoi (Anura: Centrolenidae) in southeastern Costa Rica
Revista de Biología Tropical, 2004 The Suretka glass frog, Hyalinobatrachium chirripoi, has been recently rediscovered in the south-eastern region of Costa Rica. This species was last reported in Costa Rica in the 1950’s. H. chirripoi is distinguished from H. colymbiphyllum, which appears

Three-photon excitation of quantum dots with a telecom band ultrafast fiber laser [PDF]
, 2014 We demonstrate three-photon excitation in quantum dots with a mode-locked fiber laser operating in the telecommunications band. We compare spectra and intensity dependence of fluorescence from one- and three-photon excitation of commercially available ...

Archaeometry, EarlyView.ABSTRACT New radiocarbon determinations from rice grains and bamboo have been obtained from Non Ban Jak, Northeast Thailand. These, along with charcoal, date a late Iron Age building sequence. The results come from short‐lived species and charcoal with potential inbuilt age. We built a series of Bayesian models to obtain a reliable chronology.

PROTEINS OF PAROTOID GLAND SECRETIONS FROM TOADS OF THE GENUS BUFO [PDF]
, 2000 Freeze-dried parotoid gland secretions from toads of the genus Bufo contained large proportions of protein (25-35% by weight). SDS-PAGE suggested that secretions from several species of Bufo contained mixtures of proteins in the relative molecular mass ...

Resource Availability Overrides Predator Presence in Mosquito Oviposition Habitat Selection
Entomologia Experimentalis et Applicata, EarlyView.Gravid Culex quinquefasciatus balance predation risk against resource availability when selecting oviposition sites. In outdoor mesocosms, we factorially manipulated sugarcane jaggery (resource) and notonectid predators (adult vs. nymph; caged vs. free‐swimming) across 2 years.

Signal transducer and activator of transcription-1 localizes to the mitochondria and modulates mitophagy [PDF]
, 2013 The signal transducer and activator of transcription (STAT) proteins are latent transcription factors that have been shown to be involved in cell proliferation, development, apoptosis, and autophagy. STAT proteins undergo activation by phosphorylation at
