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...

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...

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)...

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.

Utilization of satellite data for inventorying prairie ponds and lakes Utilization of satellite data for inventorying prairie ponds and lakes

By using data acquired by LANDSAT-1 (formerly ERTS- 1), studies were conducted in extracting information necessary for formulating management decisions relating to migratory waterfowl. Management decisions are based in part on an assessment ofhabitat characteristics, specifically numbers, distribution, and quality of ponds and lakes in the prime breeding range. This paper reports on a...
