Journal ArticleDOI
Succession and management of tropical dry forests in the Americas: review and new perspectives.
Mauricio Quesada,G. Arturo Sánchez-Azofeifa,Mariana Yolotl Alvarez-Añorve,Kathryn E. Stoner,Luis Daniel Avila-Cabadilla,Julio Calvo-Alvarado,Alicia Castillo,Mário M. Espírito-Santo,Marcílio Fagundes,Geraldo Wilson Fernandes,John A. Gamon,Martha Lopezaraiza-Mikel,Deborah Lawrence,Leonor Patrícia Cerdeira Morellato,Jennifer S. Powers,Frederico de Siqueira Neves,Víctor Rosas-Guerrero,Roberto Sáyago,Gumersindo Sánchez-Montoya +18 more
TL;DR: In this article, a review of the current knowledge of the ecology and management implications associated to tropical dry forest succession is presented, focusing on the use of chronosequences, plant diversity and composition, plant phenology and remote sensing, pollination, and animal-plant interactions.
Journal ArticleDOI
Evaluating factors that predict the structure of a commensalistic epiphyte-phorophyte network.
Roberto Sáyago,Martha Lopezaraiza-Mikel,Mauricio Quesada,Mariana Yolotl Alvarez-Añorve,Alfredo Cascante-Marín,Jesús M. Bastida +5 more
TL;DR: The effect of host size on the establishment of epiphytes indicates that mature forests are necessary to preserve diverse bromeliad communities and builds models of interaction probabilities among species to assess if host traits and abundance and spatial overlap of species predict the quantitative epipHYte–host network.
Book ChapterDOI
Human Impacts on Pollination, Reproduction, and Breeding Systems in Tropical Forest Plants
Mauricio Quesada,Fernando Rosas,Ramiro Aguilar,Lorena Ashworth,Víctor Rosas-Guerrero,Roberto Sáyago,Jorge A. Lobo,Yvonne Herrerías-Diego,Gumersindo Sánchez-Montoya +8 more
TL;DR: It is of central concern to understand the capacity of pollinators for transferring pollen among individuals and its consequences on plant reproduction in newly created anthropogenic landscapes.
Book ChapterDOI
Tropical Dry Forest Ecological Succession in Mexico: Synthesis of a Long-Term Study
Mariana Yolotl Alvarez-Añorve,Luis Daniel Avila-Cabadilla,Alicia Castillo,Martha Lopezaraiza-Mikel,Silvana Martén-Rodríguez,Víctor Rosas-Guerrero,Roberto Sáyago,Gumersindo Sánchez-Montoya,José Contreras-Sánchez,Francisco Javier Balvino-Olvera,Sergio Olvera-García,Sergio Lopez-Valencia,Natalia Valdespino-Vázquez +12 more
Journal ArticleDOI
Consequences of habitat fragmentation on the reproductive success of two Tillandsia species with contrasting life history strategies.
Roberto Sáyago,Roberto Sáyago,Mauricio Quesada,Ramiro Aguilar,Ramiro Aguilar,Lorena Ashworth,Lorena Ashworth,Martha Lopezaraiza-Mikel,Martha Lopezaraiza-Mikel,Silvana Martén-Rodríguez +9 more
TL;DR: It is shown that even related congeneric species may exhibit different responses to human disturbance, and plant reproductive systems, along with changes in pollinator communities associated with habitat fragmentation, may have yet undocumented consequences on gene flow, levels of inbreeding and progeny quality of dry forest tillandsias.
