Abstract

This study investigates the effects on human population density on soil properties and found significant effects in nematode abundance and soil nitrogen levels. Five locations with differing human population densities around Monteverde, Costa Rica were chosen for soil sampling to conduct chemical tests and microfauna extractions. Chi square test (p = 0.02) prove that the differing soil location caused changes in nematode abundance, and a regression between nematode abundance and soil nitrogen (R square = .96) proved a strong relationship between the two. From this study we can see the impacts of human disturbance on levels of nitrogen and nematode abundance within our soil systems.

Resumen

En este estudio investigue los efectos de la densidad poblacional en las características del suelo y encontré una correlación entre la abundancia de nematodos y los niveles de nitrógeno en el suelo. Se escogieron cinco lugares para hacer muestras del suelo con diferentes densidades poblacionales cerca de Monteverde, Costa Rica con el fin de hacer un análisis químico y hacer extracciones de micro fauna.
