Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
Chaverri Echandi, Priscila; Chaverri Echandi, Gloriana (2022)Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ... -
Life cycle and in vitro sporulation dynamics of Corinectria constricta, the causal agent of Pinus radiata stem canker, in Chile
González, Cristian D.; Morales, Rodrigo A.; Chaverri Echandi, Priscila (2020-04-07)In 2008, a canker disease caused by the fungus Corinectria constricta was detected in southern Chile. The causal agent was previously identified as Neonectria fuckeliana (now Corinectria fuckeliana), which has been associated ... -
Mycelial inhibition of Trichoderma spp. (Hypocreaceae) isolated from the cultivation of Pleurotus ostreatus (Pleurotaceae) with an extract of Pycnoporus sp. (Polyporaceae)
Talavera Ortiz, Anaid; Chaverri Echandi, Priscila; Díaz Godínez, Gerardo; Acosta Urdapilleta, María de Lourdes; Villegas Villarreal, Elba Cristina; Téllez Téllez, Maura (2020-01-07)Background and Aims: The production of edible fungi is affected by bacterial, fungal and viral diseases, which very often cause large losses. In the production of mushrooms of the genus Pleurotus, the fungi of Trichoderma ... -
Patogenicidad de tres hongos asociados a la muerte de plantas de fresa (Fragaria ananassa) y descripción ultraestructural del patosistema
Granados Montero, María del Milagro; Zúñiga Castañeda, Mariam; Chaverri Echandi, Priscila; Escudero Leyva, Efraín; Mardones Hidalgo, Melissa (2022-08-03)Introducción. El cultivo de fresa (Fragaria ananassa) es importante en Costa Rica por su alta demanda como fruta fresca y para elaboración de mermeladas.

Phylogenetic analysis of ITS data from endophytic fungi using massive parallel bayesian tree inference with exabayes
Montero Vargas, Maripaz; Umaña Jiménez, Jean Carlo; Escudero Leyva, Efraín; Chaverri Echandi, Priscila (2020-03-27)Ecological studies of fungal communities have been favored thanks to the emergence and improvement of independent culture techniques that use the ITS region as a molecular marker. This has allowed a more accurate identification ... -
Response of psychrophilic plant endosymbionts to experimental temperature increase
Seas Carvajal, Carolina; Chaverri Echandi, Priscila (2020)Countless uncertainties remain regarding the effects of global warming on biodiversity, including the ability of organisms to adapt and how that will affect obligate symbiotic relationships. The present study aimed to ... -
Step‐by‐Step Pipeline for the Ecological Analysis of Endophytic Fungi using ITS nrDNA Data
Montero Vargas, Maripaz; Escudero Leyva, Efraín; Díaz Valerio, Stefani; Chaverri Echandi, Priscila (2020-01-07)The nuclear ribosomal DNA internal transcribed spacer (ITS) is accepted as the genetic marker or barcode of choice for the identification of fungal samples. Here, we present a protocol to analyze fungal ITS data, from ... -
Taxonomía multifásica de hongos endófitos del orden hypocreales en rubiaceae de bosque natural de Costa Rica
Escudero Leyva, Efraín (2023)Los problemas fitosanitarios relacionados al café en Latinoamérica y otras áreas en el mundo, han registrado un aumento en la frecuencia y la severidad de las enfermedades producidas por hongos como Hemileia vastatrix ó ... -
Two new cellulolytic fungal species isolated from a 19th-century art collection
Coronado Ruiz, Carolina; Avendaño Vega, Roberto; Escudero Leyva, Efraín; Conejo Barboza, Geraldine; Chaverri Echandi, Priscila; Chavarría Vargas, Max (2018)The archive of the Universidad de Costa Rica maintains a nineteenth-century French collection of drawings and lithographs in which the biodeterioration by fungi is rampant. Because of nutritional conditions in which these ...
