Differential allelopathy between genders of an invasive dioecious tree on desert plants
Avendaño Gonzalez, Marcela; Badano, Ernesto Ivan; Ramírez Albores, Jorge Enrique; Flores Rivas, Joel David (2016-06)"The Peruvian peppertree (Schinus molle) is a dioecious species from South America that was introduced into central Mexico five centuries ago. This tree has invaded abandoned agricultural fields from semiarid regions, where ... -
Effect of biological soil crusts on the germination of three plant species under laboratory conditions
Pando Moreno, Marisela; Jurado Ybarra, Enrique; Flores Rivas, Joel David (2014-06)"Semiarid grasslands in northeastern Mexico contain many endemic plants and animals and are an important refuge for resident and migratory animals. Here, as in many other semiarid areas, biological soil crusts are a key ... -
Effects of shade on germination traits of the endangered cycad Dioon edule (Zamiaceae)
Yáñez Espinosa, Laura; Flores Rivas, Joel David (2016-03)"The endangered cycad Dioon edule requires shade provided by filtered sunlight under the canopy of trees or maternal plants during initial growth stages. It is known that germination improves under shade, but there is no ... -
Effects of spine-shading on aspects of photosynthesis for three cactus species
De la Rosa Manzano, Edilia; Flores Rivas, Joel David; Delgado Sánchez, Pablo (2016-06)"We evaluated the effect of spine removal on three cactus species varying in spine-shading of stems. Turbinicarpus schmiedickeanus showed the greater spine shading (c. 61 %), followed by Mammillaria zephyranthoides (43 %), ... -
Effects of wetting and drying cycles on the germination of nine species of the Chihuahuan Desert
Contreras Quiroz, Mariana del Rocio; Pando Moreno, Marisela; Flores Rivas, Joel David; Jurado Ybarra, Enrique (2016-06)"Plants from drylands have developed strategies to germinate even in places where available humidity is sporadic with large periods of drought. Previous works determined germination of cacti species as a response to ... -

Valdés Sáenz, María A.; García Quintana, Yudel; Escarré Esteve, Antonio; Flores Rivas, Joel David; Geada López, Gretel; Arteaga Crespo, Yasiel; Valdés-Sáenz, Carmen R. (2014-09)"Los bosques naturales de Pinus tropicalis Morelet en Cuba han sido alterados por prácticas inadecuadas de aprovechamiento forestal. Esta investigación tiene el objetivo de caracterizar la estructura de un bosque perturbado ... -
Factores abióticos involucrados en la facilitación entre leñosas y suculentas en el altiplano mexicano
Romo Campos, Rosa de Lourdes; Flores Flores, José Luis; Flores Rivas, Joel David; Álvarez Fuentes, Gregorio (2013-09)"Se estudiaron características fisiológicas y morfológicas de plántulas de especies leñosas (nodrizas) y suculentas (protegidas), las cuales se distribuyen en un gradiente ambiental en el Altiplano Mexicano. Del extremo ... -
Functional responses of recently emerged seedlings of an endemic Mexican oak (Quercus eduardii) under climate change conditions
Badano, Ernesto Ivan; Guerra Coss, Francisco Arturo; Gelviz Gelvez, Sandra Milena; Flores Rivas, Joel David; Delgado Sánchez, Pablo (2018)"Background: Climate change will increase temperature and reduce rainfall across temperate forests of Mexico. This can alter tree establishment dynamics within forest and in neighbouring man-made clearings. Hypotheses: ... -
Germinación de semillas de Magnolia pugana (Magnoliaceae), especie endémica y en peligro de extinción del occidente de México
Jacobo Pereira, César; Romo Campos, Rosa de Lourdes; Flores Rivas, Joel David (2016-09)"Magnolia pugana es una especie endémica y en peligro de extinción localizada en el occidente de México, que se distribuye en bosques de galería en las barrancas del sur de Zacatecas y centro-norte de Jalisco. El objetivo ... -
Heat shock effect in breaking physical dormancy in seeds of Lupinus elegans and L. rotundiflorus from Jalisco, Mexico
Robles Díaz, Erika; Jurado Ybarra, Enrique; Yáñez Espinosa, Laura; Flores Rivas, Joel David (2014-03)"Most Lupinus spp. (Fabaceae) grow in pine and pine-oak forests with natural and induced fires, and their seeds have physical dormancy, which could be broken in response to appropriate environmental signals, such as high ... -
Microambiente lumínico y morfología y fisiología foliar de Bromelia karatas (Bromeliaceae) en una selva baja caducifolia de Yucatán, México

The andean forest soil seed bank in two successional stages in northeastern Colombia
Gelviz Gelvez, Sandra Milena; Sánchez Montaño, Luis Roberto; Lopez Toledo, Leonel; Barragán Torres, Felipe (2016-12)"Background: Soil seed banks play an important role in post-disturbance regeneration and succession of species from different successional stages. Questions: 1) What is the most effective method for determining the ... -
The relevance of burial to evade acorn predation in an oak forest affected by habitat loss and land use changes
Ramos Palacios, Carlos Renato; Badano, Ernesto Ivan (2014-06)"Seed burial was proposed as an effective mechanism to evade seed predation in continuous forests. However, the relevance of burial as a mechanism to evade seed predators may be compromised in fragmented forests intensely ...
