“…The overall level of aggregation as indicated by the variance to mean ratio of mistletoe numbers per host fell within the midrange of values found in other published studies of host-mistletoe interactions (Overton 1994;Donohue 1995;Bannister & Strong 2001;Aukema & Martinez del Rio 2002;López de Buen et al 2002;Rist et al 2011). Mistletoes were aggregated at two scales: on individual trees and within plots.…”

“…The observation that taller, larger, and older trees have a higher frequency of parasitic attack and more intense infection than smaller trees is not uncommon. A common explanation is that larger and older trees could be more attractive to frugivorous birds for perching, which would therefore deposit more mistletoe seeds onto perches (Reid & Lange 1988;Overton 1994;Donohue 1995;López de Buen et al 2002). However, Reid & Stafford-Smith (2000) sug-gest that a high number of mistletoes per tree results more from the attraction of dispersers to the presence of established mistletoes on trees than to host size by itself.…”

The frequency of parasitism of the European mistletoe, Viscum album L. subsp. album, in the city of Lodz, a typical major city in Poland, was investigated. The infection prevalence and intensity of the mistletoe Viscum album subsp. album on its main host, Acer saccharinum as a function of host size was also investigated. The parasite showed a strong preference for alien, planted tree species (i.e. A. saccharinum, Populus×canadensis and Robinia pseudoacacia). In 2009-2011, V. album subsp. album was observed on 28 host taxa of trees and shrubs, which represents the highest diversity of host trees in a single locality in the Poland. Within the studied area 2147 trees were infested by mistletoe. The distribution of mistletoes (V. album subsp. album) among A. saccharinum hosts is significantly aggregated. The intensity of mistletoe infection in the silver maple trees was affected by the individual tree characteristics, such as the height of the tree. The overall level of aggregation as indicated by the variance to mean ratio of mistletoe numbers per host fell within the midrange of values found in other published studies of host-mistletoe interactions. The higher mistletoe infection prevalence in taller trees results from differential dispersal of mistletoe seeds to tall trees as well as differential survival of established mistletoes on tall trees. The incidence of mistletoe was higher in city centre (zone of high density development) than it was on the outskirts of a city (outer marginal zone). It was found that the abundant occurrence of mistletoe was recorded in the stands of increased nitrogen input, while other stands have little or no mistletoe infection present. Thus, this mistletoe species uses both passive and active uptake, which may be a selective advantage in a nutrient-poor environment or on a nutrient-deficient host species.

árboles en un rodal natural con presencia de muérdago enano: nueve sanos y nueve enfermos; con edades entre 30 y 40 años a los cuales se les realizaron análisis troncales para reconstruir su historial de crecimiento. Se consideró el grado de infección 6, con base en el sistema de clasificación de Hawksworth. Se probaron las ecuaciones de Shumacher y Chapman-Richards a fin de seleccionar el modelo más adecuado para la descripción del fenómeno. El modelo de Shumacher presentó mejores ajustes en la predicción del crecimiento. La infestación por muérdago enano lo redujo 22 % en altura, 9 % en diámetro y 50 % en volumen; además afectó en porcentajes similares al incremento corriente anual e incremento medio anual, lo cual disminuye el volumen de madera producido y aumenta el turno técnico maderable del arbolado, en un promedio de 10 años. Los resultados sugieren la aplicación de prácticas de prevención y combate del parásito, así como el establecimiento de sitios de monitoreo continuo para la generación de conocimiento sobre la relación parásito-hospedero. AbstractAlthough mistletoes are abundant in Mexico, very little is known about their behavior on different hosts. There is some work on damage assessments and less on the behavior of trees infested with varying degrees of attack. The aim of this study was to determine the effect of Arceuthobium vaginatum subsp. vaginatum in height, diameter and volume of Pinus hartwegii in the Nevado de Colima Volcano National Park. 18 trees were chosen in a natural stand in the presence of dwarf mistletoe: nine sick and nine healthy, aged between 30 and 40 years to which stem analyzes were performed to reconstruct their history of growth. Based on the classification system of Hawksworth, the degree of infection was considered 6. Schumacher and Chapman-Richards equations to find the most appropriate model for the description of the phenomenon were tested. The first one showed better fit in predicting growth. Dwarf mistletoe infestation reduced it at 22 % in height, 9 % in diameter and 50 % in volume; it also affected by similar percentages the current annual increment and the mean annual increment, which lowers the volume of timber produced and the wooden technical rotation increases, at an average of 10 years. These results suggest the application of practices to prevent and combat the parasite and the establishment of continuous monitoring sites for the generation of knowledge about the host-parasite relationship.

“…Mistletoe presence is constrained at different spatial scales by a wide range of factors, including the abiotic limitations of temperature and water availability on mistletoe growth (Zuber, 2004), the biotic specificity regarding the host type and quality (de Buen et al, 2002), and landscape-scale biotic factors influencing the abundance and movement of their main bird dispersers (García et al, 2009;MacRaild et al, 2010;Rodríguez-Cabal et al, 2007). Abiotic conditions and host quality affect the availability of suitable habitats for mistletoe establishment (Watson, 2009b), while landscape properties -such as fruiting neighborhood (Carlo and Aukema, 2005), tree spatial distribution and size structure (Aukema, 2004;Kathleen, 1995)-influence the behavior of animal dispersers and modify seed deposition (Morales and Carlo, 2006).…”

Local and landscape-scale biotic correlates of mistletoe distribution in Mediterranean pine forests

The study of the spatial patterns of species allows the examination of hypotheses on the most plausible ecological processes and factors determining their distribution. To investigate the determinants of parasite species on Mediterranean forests at regional scales, occurrence data of the European Misletoe (Viscum album) in Catalonia (NE Iberian Peninsula) were extracted from forest inventory data and combined with different types of explanatory variables by means of generalized linear mixed models. The presence of mistletoes in stands of Pinus halepensis seems to be determined by multiple factors (climatic conditions, and characteristics of the host tree and landscape structure) operating at different spatial scales, with the availability of orchards of Olea europaea in the surroundings playing a relevant role. These results suggest that host quality and landscape structure are important mediators of plant-plant and plant-animal interactions and, therefore, management of mistletoe populations should be conducted at both local (i.e. clearing of infected host trees) and landscape scales (e.g. controlling the availability of nutrient-rich food sources that attract bird dispersers). Research and management at landscape-scales are necessary to anticipate the negative consequence of land-use changes in Mediterranean forests.Key words: bird-mediated dispersal; Iberian Peninsula; land uses; landscape structure; Pinus halepensis; species distribution; Viscum album. ResumenInfluencia de factores bióticos a escala local y de paisaje en la distribución del muérdago en pinares mediterráneos El estudio de los patrones espaciales de las especies permite examinar hipótesis sobre los procesos ecológicos y factores más plausibles que determinan su distribución. Para investigar los determinantes de una especie parásita en bosques mediterráneos a escala regional, se combinaron datos sobre la presencia de muérdago (Viscum album) en Cataluña (NE de la Península Ibérica) extraídos del inventario forestal con diferentes variables explicativas por medio de modelos mixtos generalizados. La presencia de muérdago en masas de Pinus halepensis parece estar determinada por múltiples factores (condiciones climáticas, características del árbol hospedante, y estructura del paisaje) que operan a diferentes escalas espaciales, jugando los cultivos de Olea europaea un papel relevante. Los resultados sugieren que la calidad de los árboles hospedantes y la estructura del paisaje son importantes mediadores de las interacciones planta-planta y planta-animal y, por tanto, la gestión de las poblaciones de muérdago debería llevarse a cabo tanto a nivel local (es decir, cortando árboles hospedantes infectados) como de paisaje (por ejemplo, controlando la disponibilidad de hábitats ricos en nutrientes que atraen a las aves dispersantes). La investigación y gestión a escala de paisaje son necesarias para prevenir las consecuencias negativas de los cambios de uso del suelo en los bosques mediterráneos.Palabras clave: dispersión mediada por aves; Penín...
