Is Oncidium poikilostalix an invasive species? Population ecology and reproductive behavior of this epiphytic orchid in Chiapas, Mexico

Background and Aims: Biological invasions are considered as second to habitat loss as a cause of the extinction of species. The study of population dynamics is particularly relevant for species with expansive behavior. The aims of this study were to: (1) evaluate the population ecology of Oncidium p...

description Background and Aims: Biological invasions are considered as second to habitat loss as a cause of the extinction of species. The study of population dynamics is particularly relevant for species with expansive behavior. The aims of this study were to: (1) evaluate the population ecology of Oncidium poikilostalix in shaded coffee plantations in Mexico, (2) evaluate the reproductive behavior of O. poikilostalix in this habitat, and (3) determine whether this orchid should be considered as an invasive species. Methods: During 2013-2015, most of the individuals of the Mexican population of O. poikilostalix (located south of the state Chiapas) were marked and measured. Additionally, the flower and fruit production (first flowering and repeated flowering), mortality and recruitment of new individuals were registered annually, and its potential distribution was modeled. Key results: Within this period a population increase of 1.11% was observed, with a proportional increase in the number of flowers and fruits. There was a strong correlation between the leaf area of individuals and the production of flower spikes (R=0.690, p

Key results: Within this period a population increase of 1.11% was observed, with a proportional increase in the number of flowers and fruits. There was a strong correlation between the leaf area of individuals and the production of flower spikes (R=0.690, p<0.001) and flowers (R=0.775, p<0.001). The number of mature individuals that had repeated flowering varied from 47.1% in 2013 to 22.5% in 2015. There was also correlation between the leaf area of individuals with the fact that they do not flower, flower once and repeated flowering (X2=277.65, p<0.001). The Mexican population of O. poikilostalix is located on the northern limit of the potential distribution of this species. Conclusions: It is unlikely that O. poikilostalix behaves as an invasive species. Despite being a locally abundant taxon, with an apparently healthy population established in traditional shaded coffee plantations, its distribution in Mexico is limited, which may represent a serious risk to its survival in the country. Antecedentes y Objetivos: Las invasiones biológicas se consideran la segunda causa de extinción de especies después de la destrucción del hábitat. Cuando se trabaja con especies con una tendencia expansiva, los estudios de dinámica poblacional son particularmente relevantes. Los objetivos de este estudio fueron: (1) evaluar la ecología poblacional de Oncidium poikilostalix en cafetales de sombra en México, (2) evaluar el comportamiento reproductivo de O. poikilostalix en este hábitat, y (3) determinar si esta orquídea se debe considerar como una especie invasora. Métodos: Durante 2013-2015 se marcaron y midieron la mayoría de los individuos de la población mexicana de O. poikilostalix (localizada al sur del estado de Chiapas). Además, se registraron anualmente la producción de flores y frutos (primera floración y floración repetida), la mortalidad y el reclutamiento de nuevos individuos, y se modeló su distribución potencial. Resultados clave: Dentro de este periodo se observó un incremento poblacional de 1.11%, con un aumento proporcional en el número de flores y frutos. Existe una fuerte correlación entre el área foliar de los individuos, y la producción de espigas (R=0.690, p<0.001) y flores (R=0.775, p<0.001). El número de individuos adultos que tuvieron floración repetida varió de 47.1% en 2013 a 22.5% en 2015. También se encontró correlación entre el área foliar de los individuos y el hecho de que no florezcan, florezcan una vez, o presenten floración repetida (X2=277.65, p<0.001). La población mexicana de O. poikilostalix se localiza en el límite norte de la distribución potencial de esta especie. Conclusiones: Es poco probable que O. poikilostalix sea una especie invasora. A pesar de ser un taxon localmente abundante, con una población aparentemente sana establecida en cafetales tradicionales de sombra, su área de distribución en México aún es restringida, lo que puede representar un grave riesgo para su supervivencia en el país.]]></description><identifier>ISSN: 2448-7589</identifier><identifier>ISSN: 0187-7151</identifier><identifier>DOI: 10.21829/abm125.2018.1370</identifier><language>eng</language><subject>conservación ; conservation ; demografía ; demography ; epiphytic orchids ; floración ; flowering ; orquídeas epífitas</subject><ispartof>Acta botánica mexicana, 2018 (125), p.215-230</ispartof><rights>LICENCIA DE USO: Los documentos a texto completo incluidos en Dialnet son de acceso libre y propiedad de sus autores y/o editores.
