Arthropods From The Panamae Forest Floor

Core samples were taken from the forest floor at 0 m beneath logs 1 5 and 2 5 m distances from the logs and invertebrates were extracted from the litter and fermentation layer using tullgren.

Arthropods from the panamae forest floor. In comparison with the forest sites species diversity was reduced by 45 figures 2e h individual density by 48 figures 2i l and biomass by 52 figures 2m p respectively. Published december 15 2012 though birds trees and orchids call the tropical rain forest home they are immensely outnumbered by tiny arthropods such as insects spiders and millipedes. We found that oil palm plantations contained fewer species fewer individuals and lower biomass of arthropods than the forest sites did figures 2a d. This means that arthropod communities in the leaf litter were roughly halved in oil palm plantations compared with rainforests.

A new study found a vast array of species of arthropods in a small patch of panamanian rainforest 25 000 species. Arthropod are insects plus spiders mites centipedes and pretty much everything else that. We conclude that at a local scale arthropod abundance is related to forest floor mass habitat space while arthropod diversity is related to forest floor nutrient concentrations habitat quality. We measured arthropod abundance biomass taxonomic richness diversity and community composition and focussed predominantly on faunal responses to chemical changes in the soil as a result of long term litter manipulation.

The problems in elucidating the living relationships between mites and other arthropods due to biological complexities and physical difficulties are reviewed. Miller says the leafcutter ant is one of thousands of arthropod species in panama s san lorenzo forest. Studies in a tropical forest in panama have shown clear differences in arthropod community composition and abundance related to forest floor depth with an increase in arachnida at greater litter. There were 300 species of arthropod for every 1 mammal.

Differences in arthropod community composition between treatments and horizons correlated with phosphorus concentration and dry mass of the forest floor.
