Native American Pomo communities who live in the Northern Coastal range of California and consume acorns from tanoak trees as part of traditional diets are facing the potential loss of many culturally important trees to sudden oak death. Pomo and other Native American communities are reluctant to use the protective fungicide, potassium phosphonate, on trees used for acorn collection without inf...

The patterns of seedling recruitment in animal-dispersed plants result from the interactions among environmental and behavioral variables. However, we know little on the contribution and combined effect of both kinds of variables. We designed a field study to assess the interplay between environment (vegetation structure, seed abundance, rodent abundance) and behavior (seed dispersal and predat...

Numerous interactions between plants and animals vary in their outcome predation mutualism. Depending on the costs benefits, relationship is placed at one end of scale or other. A thin line separates both interactions. Acorn consumption by rodent species has been considered a relationship. Rodents consume acorns, which cost to oaks as they are prevented from colonizing new places. The aim this ...

Trees in the beech or oak family (Fagaceae) have a mutualistic relationship with scatter-hoarding rodents. Rodents obtain nutrients and energy by consuming seeds, while providing seed dispersal for the tree by allowing some cached seeds to germinate. Seed predation and caching behavior of rodents is primarily affected by seed size, mechanical protection, macronutrient content, and chemical anti...

Eastern deciduous forests are populated with a variety of hardwood species, with composition at large scales determined by a complex interplay of temperature, moisture, and disturbance. An understanding of seed production is important in the context of forest regeneration and wildlife management. We analyzed time series data obtained from the literature to investigate (1) the effects of life-hi...
