Species interactions have long been predicted to increase in intensity toward the tropics and low elevations because of gradients climate, productivity, or biodiversity. Despite their importance for understanding global ecological evolutionary processes, plant-animal interaction are particularly difficult test systematically across large geographic gradients, evidence from smaller, disparate studies is inconclusive. By measuring postdispersal seed predation using 6995 standardized depots...
Terrestrial tri–trophic interactions account for a large part of biodiversity, with approximately 75% represented in plant–insect–parasitoid interactions. Herbivore diet breadth is an important factor mediating these interactions, as specialization can influence how herbivore fitness affected by plant traits. We investigated phytochemistry, immunity, and mediate plant–caterpillar–parasitoid on the tropical genus Piper (Piperaceae) at La Selva Biological station Costa Rica Yanayacu Station...
Deciphering the ecological roles of plant secondary metabolites requires integrative studies that assess both allocation patterns compounds and their bioactivity in interactions. Secondary have been primarily studied leaves, but many are unique to fruits can numerous potential interactions with mutualists (seed dispersers) antagonists (pathogens predators). We described 10 alkenylphenol from species Piper sancti-felicis (Piperaceae), quantified intraplant across tissues fruit development,...
Many host-plants exhibit genetic variation in resistance to pathogens; however, little is known about the extent which pathogen influences other members of host-plant community, especially arthropods at higher trophic levels. We addressed this knowledge gap by using a common garden experiment examine whether genotypes Populus trichocarpa varied leaf-blistering pathogen, Taphrina sp., and density web-building spiders, dominant group predatory arthropods. In addition, we examined spider was...
Abstract Species interactions have long been predicted to increase in intensity towards the tropics and low elevations, due gradients climate, productivity, or biodiversity. Despite their importance for understanding global ecological evolutionary processes, plant-animal interaction are particularly difficult test systematically across large geographic gradients, evidence from smaller, disparate studies is inconclusive. By measuring post-dispersal seed predation using 6980 standardized...
Abstract Urbanization can profoundly disrupt local ecology. But while urban areas now stretch across latitudes, little is known about urbanization’s effects on macroecological patterns. We used standardized experiments to test whether urbanization disrupts latitudinal gradients in seed predation, a pattern that shapes community assembly and diversity. Using >56,000 seeds, we compared predation urbanized natural 14,000 km of latitude, spanning the Americas. Predation increased 5-fold from...
