The aim of this research was the genetic characterization of 218 accessions of Cucurbita moschata Duchesne, a squash, and its relationship with morphological characteristics of agronomic interest, which are part of the ...

Wild crop relatives are an important source of genetic diversity for crop improvement. Diversity estimates are generally lacking for many wild crop relatives. The objective of the present study was to analyze how genetic ...

Information theory and its indices were developed for human communication to predict the amount of information transferred in a message. One such index, the Shannon-Weiner index (SWI), has often been used to analyse ...

In the Neotropics, captive vespertilionid bats substantially reduce their metabolic rate at low ambient temperatures, similar to their temperate counterparts, whereas the ability of phyllostomids to lower metabolic rate ...

Whiteflies are an insect group that comprises multiple species and biotypes, capable of affecting crops by phloem feeding, virus transmission and promotion of fungal colonization. The distribution of these pests is worldwide. ...

This study deals with the biology of Doru taeniatum, (Forficuüdae), particulary the habitat, feeding, reproduction, maternal care, and nymphal stages. The density of adults is higher in the older corn plants. The earwings ...

In September 2008, a survey of whiteflies and whitefly-borne viruses was performed in 11 pepper-growing greenhouses in the province of Cartago, Costa Rica. During this survey, the vast majority of sweet pepper (Capsicum ...

El arsénico es uno de los elementos más tóxicos liberados al ambiente, lo que lo convierte en una amenaza para los ecosistemas y la salud humana. Justicia pectoralis es una planta herbácea de rápido crecimiento y tolerante ...

A new species of Brachionidium from Costa Rica is described and illustrated. Brachionidium cornu-nigricum, from the Volcán Cacho Negro, a remote, previously unexplored location in Costa Rica, is most similar to B. filamentosum. ...

We investigated the ontogenetic changes of two call types, the inquiry call and the response call, which comprise an interactive communication system in Spix's disc-winged bats, Thyroptera tricolor. We documented structural ...
