Tropical Tritrophic Interactions: Nasty Hosts andUbiquitous Cascad es
TL;DR: In the tropics, the high diversity of species at all trophic levels combined with increased chemical defense and predation intensity create ideal opportunities for interesting research in community ecology.
Journal ArticleDOI
The importance of petiole structure on inhabitability by ants in Piper sect. Macrostachys (Piperaceae)
TL;DR: It is indicated that minor modiÞcations in a smallnumber of petiolar characters make the difference between petioles that are suitable for habitation by ants and those that are not.
Journal ArticleDOI
Isolation and characterization of eleven polymorphic microsatellite loci from an endemic species, Piper polysyphonum (Piperaceae)
TL;DR: The polymorphic microsatellite DNA markers reported here should provide a helpful means to address questions concerning population structure and demographic history of P. polysyphonum for conservation efforts.
Journal ArticleDOI
Chemical composition of essential oils of Piper jacquemontianum and Piper variabile from Guatemala and bioactivity of the dichloromethane and methanol extracts
Sully M. Cruz,Armando Cáceres,Luis E. Alvarez,Julio Morales,Miriam Anders Apel,Amélia T. Henriques,Efrain Salamanca,Alberto Giménez,Yelkaira Vasquez,Mahabir P. Gupta +9 more
TL;DR: The essential oils from two native species from Guatemala were studied for their chemical composition and the dichloromethane and methanol extracts for their biological activity and none of the extracts from the two species was active against Aedes aegypti larvae and Artemia salina nauplii.
Journal ArticleDOI
Piper kelleyi, a hotspot of ecological interactions and a new species from Ecuador and Peru
TL;DR: Piper kelleyi is a member of the Macrostachys clade of the genus Piper and supports a rich community of generalist and specialist herbivores, their predators and parasitoids, as well as commensalistic earwigs, and mutualistic ants.

A revised medium for rapid growth and bio assays with tobacco tissue cultures
Toshio Murashige,Folke Skoog +1 more
TL;DR: In vivo redox biosensing resolves the spatiotemporal dynamics of compartmental responses to local ROS generation and provide a basis for understanding how compartment-specific redox dynamics may operate in retrograde signaling and stress 67 acclimation in plants.
Journal ArticleDOI
Confidence limits on phylogenies: an approach using the bootstrap.
TL;DR: The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.

MODELTEST: testing the model of DNA substitution.
David Posada,Keith A. Crandall +1 more
TL;DR: The program MODELTEST uses log likelihood scores to establish the model of DNA evolution that best fits the data.
Journal ArticleDOI
Dating of the human-ape splitting by a molecular clock of mitochondrial DNA.
TL;DR: A new statistical method for estimating divergence dates of species from DNA sequence data by a molecular clock approach is developed, and this dating may pose a problem for the widely believed hypothesis that the bipedal creatureAustralopithecus afarensis, which lived some 3.7 million years ago, was ancestral to man and evolved after the human-ape splitting.
