Diplochory: are two seed dispersers better than one?
Diplochory is seed dispersal by a sequence of two or more steps or phases, each involving a different dispersal agent. Here, we describe five forms of diplochory and derive general characteristics of… Expand
Area use by white-lipped and collared peccaries (Tayassu pecari and Tayassu tajacu) in a tropical forest fragment
We present the first long-term radio telemetry study of area use by white-lipped and collared peccaries in a tropical forest fragment. Population densities of both species in a 2178-ha fragment of… Expand
Direct Observations of Owls and Heteromyid Rodents: Can Predation Risk Explain Microhabitat Use?
Coexisting heteromyid rodent species of North American deserts differ in habitat use and in locomotory morphology. Quadrupedal species forage primarily in struc- turally complex microhabitats, such… Expand

Natural and anthropogenic boundaries have been shown to affect population dynamics and population structure for many species with movement patterns at the landscape level. Understanding population… Expand
PATTERNS OF ECTOMYCORRHIZAL-FUNGI CONSUMPTION BY SMALL MAMMALS IN REMNANT OLD-GROWTH FORESTS OF THE SIERRA NEVADA
Abstract We investigated fungal consumption and resulting patterns of potential spore dispersal by 6 small mammals in old-growth habitat in the Sierra Nevada of the United States, a region in which… Expand
Nongame Bird Community Responses to Sagebrush Invasion of Crested Wheatgrass Seedings
Interrelationships among northern flying squirrels, truffles, and microhabitat structure in Sierra Nevada old-growth habitat
During 1997-1998, we investigated the influence of both the relative abundance of truffles, preferred food items, and microhabitat structure on the occurrence of northern flying squirrels ( Glaucomys… Expand
SEEDLING RECRUITMENT IN ORYZOPSIS HYMENOIDES: ARE DESERT GRANIVORES MUTUALISTS OR PREDATORS?
- W. S. Longland, W. S. Longland, S. Jenkins, S. B. V. Wall, Joseph A. Veech, S. Pyare
- 1 November 2001
Granivorous animals that cache as well as consume seeds may actually serve as mutualists to their plant resources. Seeds of Indian ricegrass (Oryzopsis hymenoides), a perennial bunchgrass in North… Expand
Food abundance determines distribution and density of a frugivorous bird across seasons
Although food abundance is a principal determinant of distribution and abundance of many animals, most previous studies have not quantitatively assessed its importance relative to other factors that… Expand
Sex and age affect vulnerability of desert rodents to owl predation
Pelvic morphology was examined to distinguish sexes of three prey species eaten by great horned owls, and age classes of one of these species. Comparisons of sex ratios in prey populations with… Expand
