Energy allocation patterns of a sprouting and nonsprouting species of Arctostaphylos in the California chaparral Energy allocation patterns of a sprouting and nonsprouting species of Arctostaphylos in the California chaparral
The r- and K-selection theory was used to generate testable hypotheses about patterns of energy allocation in two chaparral shrubs of different reproductive strategies. Terminal-branchlet vegetative and reproductive biomass of the nonsprouting Arctostaphylos glauca and the sprouting A. glandulosa were sampled in a 23-year-old and a 90-year-old stand of chaparral to test the predictions...

Tool use in a social insect and its implications for competitive interactions Tool use in a social insect and its implications for competitive interactions
Four species of myrmicine ants, Aphaenogaster rudis, A. treatae, A. tennesseensis, and A. fulva, use pieces of leaf, mud, and sand grains as tools to carry soft foods from distant sources to the colony. Tools are tended on the food and removed by colony members without regard to which individual brought the tool. Food is gathered more efficiently by tool use than by internal transport...

Differential seed predation on two species of Arctostaphylos (Ericaceae) Differential seed predation on two species of Arctostaphylos (Ericaceae)
The fire-prone California chaparral contains two sympatric species of shrubs: Arctostaphylos glauca and A. glandulosa. A previous study showed that in a stand where both species had similar amounts of coverage, A. glauca had fewer seeds in the soil. We attempt to answer the questions: 1) Could ground-foraging seed predators produce the lower population of A. glauca seeds in the soil? 2)...

The abundance and diversity of the herpetofaunas of tropical forest litters The abundance and diversity of the herpetofaunas of tropical forest litters
Quantitative and qualitative samples of amphibian and lizard faunas were taken from forest litter in Costa Rica and compared with similar samples collected in Borneo, the Philippines, and Panama. Animal abundance is about ten times greater in Costa Rican lowland wet forest than in Borneo. Radically different routes and rates of energy flow are postulated to account for the difference. In...

Primates and their habitats in northern Colombia with recommendations for future management and research Primates and their habitats in northern Colombia with recommendations for future management and research
This report covers a survey of forests and wild primates carried out by its authors in northern Colombia during May, July, and August 1974. The results of a 1973 field report on this report by Bernstein et al. (1) are also included.
