Murici Ecological Station an average of . The dominant vegetation is dense rainforest in the Atlantic Forest biome. In the best preserved areas, mostly at the higher elevations, the forest forms a fairly uniform closed canopy up to high that provides shade and retains moisture. Tree species include murici ("Byrsonima sericea"), "Schefflera morototoni", "Parkia pendula", "Tabebuia" species, "Pseudobombax" species, "Bowdichia virgilioides", "Tapirira guianensis", "Handroanthus impetiginosus" and "Protium" species. The understory contains seedlings of trees, palms such as "Euterpe catinga", and many lianas and epiphytes, such as "Araceae", "Orchidaceae" ("dimerandra" species, "Dichaea" species, "Rodriguezia" species, "Cattleya labiata", "Pleurothallis" species, "Epidendrum" species, "Oncidium" species and
Portia labiata occasionally jump on an insect. However, "Portia"s are not very good at catching moving insects and often ignore them, while some other salticid genera, especially the quick, agile "Brettus" and "Cyrba", perform well against small insects. When a "Portia" stalks another jumping spider, the prey generally faces the "Portia" and then either runs away or displays as it does to another member of its own species. The webs of spiders on which "Portia"s prey sometimes contain dead insects and other arthropods which are uneaten or partly eaten. "P. labiata" and some other "Portia"s such as "P. fimbriata" (in Queensland) and
