Notes

Abstract:
Spatial distributions of mistletoe are noticeably clustered but unexamined in Monteverde, Costa Rica. To better understand their spatial structure, I examined the dispersion of two species of epiphytic mistletoe (Antidaphne viscoidea: Eremolepidaceae and Phoradendron undulatum: Viscaceae) within and between host trees. Six sites on one hill in Cañitas, Costa Rica were surveyed for data relating to dispersion structure (nearest neighbor distance and frequency within host trees). Additional study was done on the spatial dispersion on the host tree Psidium guajava, and it was found to have clustered dispersions. Indices of dispersion and tests comparing observed results to Poisson distributions showed A. viscoidea and P. undulatum were distributed contagiously within host trees and between host trees. I suggest this may be due to bird disperser foraging behavior. ( , )
Abstract:
Las distribuciones espaciales del matapalo se agrupan notablemente pero no fueron examinadas en Monteverde, Costa Rica. Para entender mejor su estructura espacial, examiné la dispersión de dos especies de matapalo de epiphytic (Antidaphne viscoidea: Eremolepidaceae y Phoradendron undulatum: Viscaceae) dentro de y entre árboles hospederos. Seis sitios en una colina en Cañitas, Costa Rica fueron encuestados para obtener los datos que relacionan a la estructura de la dispersión (distancia más cercana del vecino y frecuencia dentro de los árboles hospederos). Se hizo un estudio adicional en la dispersión espacial de Psidium guajava, árbol huespued, y se encontró que tienen dispersiones agrupadas. Los índices de dispersión y pruebas que comparan los resultados observados de las distribuciones de Poisson mostraron A. viscoidea y P. undulatum se distribuyeron por contagio dentro de los árboles hospederos y entre los arboles hospederos. Sugiero que esto puede ser debido al comportamiento de forrajeo de las aves dispersoras.

Spatial distributions of mistletoe are noticeably clustered but unexamined in Monteverde, Costa Rica. To better
understand their spatial structure, I examined the dispersion of two species of epiphytic mistletoe (Antidaphne
viscoidea: Eremolepidaceae and Phoradendron undulatum: Viscaceae) within and between host trees. Six sites
on one hill in Caitas, Costa Rica were surveyed for data relating to dispersion structure (nearest neighbor
distance and frequency within host trees). Additional study was done on the spatial dispersion on the host tree
Psidium guajava, and it was found to have clustered dispersions. Indices of dispersion and tests comparing
observed results to Poisson distributions showed A. viscoidea and P. undulatum were distributed contagiously
within host trees and between host trees. I suggest this may be due to bird disperser foraging behavior.
