Seasonality of a Diverse Beetle Assemblage Inhabiting Lowland Tropical Rain Forest in Australia
One of the least understood aspects of insect diversity in tropical rain forests is the temporal structuring, or seasonality, of communities. We collected 29,986 beetles of 1473 species over a 4-yr period (45 monthly samples), with the aim to document the temporal dynamics of a trophically diverse beetle assemblage from lowland tropical rain forest at Cape Tribulation, Australia. Malaise and fl...
متن کاملSpatial Distribution and Interspecific Associations of Tree Species in a Tropical Seasonal Rain Forest of China
Studying the spatial pattern and interspecific associations of plant species may provide valuable insights into processes and mechanisms that maintain species coexistence. Point pattern analysis was used to analyze the spatial distribution patterns of twenty dominant tree species, their interspecific spatial associations and changes across life stages in a 20-ha permanent plot of seasonal tropi...
متن کاملNutrient acquisition, soil phosphorus partitioning and competition among trees in a lowland tropical rain forest.
We hypothesized that dinitrogen (N2 )- and non-N2 -fixing tropical trees would have distinct phosphorus (P) acquisition strategies allowing them to exploit different P sources, reducing competition. We measured root phosphatase activity and arbuscular mycorrhizal (AM) colonization among two N2 - and two non-N2 -fixing seedlings, and grew them alone and in competition with different inorganic an...
متن کاملDistribution and Turnover Rate of a Population of Atta cephalotes in a Tropical Rain Forest in Costa Rica
A population of Atta cephalotes was surveyed in 1989 and 1991 at the La Selva Biological Station in Costa Rica. Nests were mapped along trails that passed through old growth forest. Estimates of basic demographic parameters were examined in relationship to general soil categories, suggesting that colony mortality and natality is related to soil type. Results indicated that the population is inc...
متن کاملThe tropical rain forest: a nonrenewable resource.
On the other hand, it has often been stated that the tropical rain forests (tall evergreen forests in tropical warm and humid regions) around the world must be protected and conserved for the future generations (1). It has also been stated that it is most important that knowledge about the structure, diversity, and function of these ecosystems has priority in future biological research (2). Unf...
