“…All of these processes could contribute to population maintenance in stochastic disturbances (Alfonso-Corrado et al 2007, Jacquemyn et al 2006, Sletvold & Rydgren 2007. Moreover, the population density is high in relation to other natural populations of Geonoma species (Table 4) and is similar to the density found for the abundant Geonoma orbignyana (Rodríguez Butiricá et al 2005).…”

“…These vital rates can respond to temporal environmental heterogeneity caused by natural events such as fire, hurricanes, low annual precipitation, high mean temperature, high seed predation and high herbivory (Elderd & Doak 2006, Evans et al 2008, Pascarella & Horvitz 1998, Ticktin 2003. Plant populations intensively influenced by natural disturbances have a high probability of changing vital rates or have high resilience following disturbance (Alfonso-Corrado et al 2007, Jacquemyn et al 2006, Sletvold & Rydgren 2007. These natural environmental disturbances can be deterministic, with regular periodic fluctuations, or stochastic, when the occurrence of the event has a probability distribution but cannot be predicted with certainty.…”

Effects of stochastic herbivory events on population maintenance of an understorey palm species ( Geonoma schottiana) in riparian tropical forest.Abstract: Plant populations can respond to temporal environmental heterogeneity caused by natural disturbances, such as herbivory. Palm individuals of several species are preyed upon by mammals, but the effects of such herbivory events on population dynamics remain poorly known. To evaluate the effects of environmental stochasticity on a Geonoma schottiana (Arecaceae) population, we surveyed annually 40 permanent 20 × 10-m plots in a riparian tropical forest over 5 y (2000)(2001)(2002)(2003)(2004) and results were analysed using matrix models. The population growth rate (λ) was in equilibrium during the study period and only one bad year was identified (2002)(2003), which had a higher mortality of juvenile individuals due to herbivory. Additionally, the bad year had a higher mortality of reproductive individuals than the other periods. The stasis matrix elements of the later life stages were the vital rates with highest elasticities. The mortality of juvenile and reproductive individuals had a negative contribution to λ in the bad year. Conversely, the growth of infant and juvenile individuals and the clonal growth of juveniles were the vital rates with highest contribution to stability maintenance of λ in the bad year in a life-table response experiment. The palm population had a high individual density, high proportion of the initial life stages, clonal growth, high fertility, abundant seed bank and high seedling recruitment. Despite these traits, if stochastic herbivory events occur frequently over a long period of time, the population will have a negative growth rate and the probability of local extinction will be very high.

“…At these sites two plots of 400 m 2 (20 × 20 m) were established, separated from one another by 1500 m, with the exception of the site of Cueva del Tigre, where only one plot was made due to a small population size. From each sampled plot the following information was obtained: (1) diameter at breast height (DBH) for adult individuals and (2) ground-line diameter for seedlings following Alfonso-Corrado et al [38]. O. mexicana individuals were classified into five categories of stage size class based on the size range of field data: (1) 0.1-1.0 cm, (2) 1.1-5.0 cm, (3) 5.1-10 cm, (4) 10.1-40 cm and (5) >40.1 cm in diameter.…”

Abstract:The tropical montane cloud forests are recognized as one of the most biodiverse ecosystems. In spite of this, they are among the most threatened ecosystems in the world. This study integrates three ecological approaches generally studied separately: climate change scenery, ecological niche and population dynamics of Oreomunnea mexicana (an endangered and relict species), to understand how environmental change affects the population structure in the cloud forest that will allow its conservation. Potential distribution under future climatic scenarios of the species at national and regional levels was generated from the Maxent algorithm. Also, the current abundance, distribution and the ecological niche of the species were analyzed at the regional level. Changes in potential distribution under two climatic models suggest a habitat reduction from 36% to 55% nationally, and 2% to 9% at a regional level, for 2050 and 2070, respectively. The current distribution of the species is fragmented and consists of subpopulations that have spatial structures of aggregated populations and a size structure in reversed "J" form. The ecological niche of the species is highly specialized and sensitive to environmental changes. O. mexicana is a flagship species of biological and cultural importance to the region's inhabitants and could be fundamental to the conservation of tropical montane cloud forests.

“…have survived after severe logging due to their ability to produce sprouts. Additionally, a demographic study carried out by Alfonso-Corrado et al (2007) showed that clonal growth was more important to the population growth rate than seed production, suggesting that the former is crucial for the regeneration of these species in Sierra Fría, Aguascalientes, Mexico. Thus, for restoration purposes it is convenient to use species that produce sprouts to rehabilitate degraded areas.…”

Background: Uncontrollable urban expansion and population growth converted Mexico City into one of the largest cities of the world. Ravines remain important oak forest relicts that should be conserved and restored to recover the biodiversity and the ecological services they provide. Question:Is an open area equally appropriate for ecological restoration as is the forest edge? Does plant performance of introduced species vary between the open area and the forest edge? Study species: Prunus serotina, Quercus rugosa, and Crataegus mexicana. Study site: Oak forest in Barranca de Tarango, Mexico City; July 2010 to July 2012. Methods: Plants of these species were planted in the forest edge and in an open area adjacent to it, where soil properties and light conditions were measured. Results: Soil properties and leaf area index were better and significantly larger, respectively, in the forest edge than in the open area. Stem height, basal area and number of sprouts of these plants did not differ between sites or years. Plants of C. mexicana produced the largest number of sprouts, followed by Q. rugosa. Survival of plants was similar in the open area and the forest edge; however, P. serotina had the lowest survival, and C. mexicana the highest. Conclusions: Q. rugosa and C. mexicana with higher survival are more likely to perform better in both sites than P. serotina, on account of their ability to produce more sprouts. The forest edge is better than the open area for introducing native species in Barranca de Tarango. Low performance of these species was mainly due to the construction of a highway that crosses the study area. Key words: forest edge, oak forest, ravine, restoration, sprouts. Restauración de un bosque de encino degradado en la Ciudad de México mediante introducción de especies arbóreas nativas ResumenAntecedentes: La expansión urbana y el crecimiento poblacional convirtieron a la Ciudad de México en una de las más grandes del mundo. Las barrancas, como relictos importantes de bosques de encinos, deben ser conservadas y restauradas para recuperar la biodiversidad y los servicios ambientales que proporcionan. Preguntas: ¿Una zona abierta es igualmente apropiada para la restauración ecológica como lo es el borde del bosque? ¿El desempeño de especies introducidas varía entre la zona abierta y el borde del bosque? Especies de estudio: Prunus serotina, Quercus rugosa y Crataegus mexicana. Sitio de estudio: Bosque de encino en la Barranca de Tarango, Ciudad de México; julio de 2010 a julio 2012. Métodos: Estas especies se plantaron en el borde del bosque y en un área abierta adyacente a éste, donde se midieron propiedades del suelo y condiciones lumínicas. Resultados: Las propiedades del suelo fueron mejores y el índice de área foliar significativamente mayor en el borde que en el área abierta. La altura, área basal del tallo y el número de rebrotes no difirieron entre sitios ni entre años. Plantas de C. mexicana produjeron la mayor cantidad de rebrotes, seguidas de Q. rugosa. La supervivencia fue similar...
