On the reasons that natural regeneration is important for species coexistence in tropical forests

open access: yesColombia Forestal, 2014
Plant regeneration plays a critical role in the maintenance of species diversity in tropical rainforests. This is a multistage process, including seed production, dispersal, germination and subsequent seedling establishment.

Two decades of demography reveals that seed and seedling transitions limit population persistence in a translocated shrub [PDF]

open access: yesAnnals of Botany, 2014
Olearia flocktoniae is an endangered shrub that was passively translocated from its natural ecosystem, where it has since gone extinct. This study aimed to determine sensitivities vital to populations persisting in human-created areas.Population colonization, longevity and extinction were investigated over 20 years using 133 populations.

Forest Densification and Pollution Rival Climate in Driving US Tree Demographic Change. [PDF]

open access: yesGlob Chang Biol
Forests across the contiguous United States are responding to simultaneous changes in climate, atmospheric pollution, and forest density, yet the relative importance of these drivers for tree demographic rates has rarely been compared. Using two decades of nationwide forest inventory data, we quantified the sensitivity of recruitment, growth, and ...

Recruitment and mortality of Rhizophora mangle L. seedlings in the Tropical Southwestern Atlantic mangrove [PDF]

open access: yesBrazilian Journal of Biology
Studies in the long-term recruitment and mortality of mangrove seedlings can help to understand mangrove demography and its relationship with climatic variables, environmental restoration and advances in the ecology of this ecosystem.

Population dynamics of a long-lived alpine plant with sexual and clonal reproduction [PDF]

open access: yes, 2006
This thesis focuses on the demography, reproduction, and pre-dispersal seed predation of the alpine clonal plant Geum reptans. In chapter 2, I studied the population dynamics of G.

Phylogenetic and Functional Diversity of Fleshy-Fruited Plants Are Positively Associated with Seedling Diversity in a Tropical Montane Forest

open access: yesFrontiers in Ecology and Evolution, 2017
Mutualistic interactions between plants and animals can affect both plant and animal communities, and potentially leave imprints on plant demography. Yet, no study has simultaneously tested how trait variation in plant resources shapes the diversity of ...

Demographic analysis of Agave angustifolia (Agavaceae) with an emphasis on ecological restoration

open access: yesBotan‪ical Sciences, 2016
We studied the demography of two populations of Agave angustifolia, one in a preserved tropical dry forest (Xochicalco), and the other one in a pastureland area used for cattle grazing (Tembembe), to test whether populations are likely to thrive on the ...

Simulation of oak early life history and interactions with disturbance via an individual-based model, SOEL.

open access: yesPLoS ONE, 2017
Early tree life history and demography are driven by interactions with the environment such as seed predation, herbivory, light availability, and drought.

Seedling Resistance to Stagonospora nodorum Blotch in Wheat Genotypes [PDF]

open access: yes, 2013
In two independent experiments set up in the greenhouse the seedling resistance to Stagonospora nodorum blotch was investigated in 92 varieties, breeding lines and genotypes with a known genetic background.
