Resumen:
The Brazilian coastal zone is widely used as a source of recreation by the
population, especially the beaches, where diverse tourist activities are practiced, which
cause a series of impacts to the communities that exist there. Thus, the objective of this
research was to understand if the impacts caused by anthropic actions interfere
in the life cycle of microscopic invertebrates called meiofauna and as
these organisms respond to these environmental stresses. Were realized
collections of biosedimentological material over 5 months. The study was
run on two beaches in Paraíba: three points at Praia do Bessa, among these,
a spot in a place where the beach still has natural conditions, two in places
of intense tourist activity and finally, a fourth spot on Intermares beach, being
this used as a control. The results indicated that in the points where there is a
greater tourist flow the variables of relative abundance, frequency of occurrence and
density, showed a decline in values, while for the points where
there is no visible flow of tourists, the numbers were high. The results indicate,
that the intense tourist activity can interfere quali-quantitatively in the structure of the
meiofaunistic community.
