The Amazon region, being diverse, is potentially important for
botanical studies. In this biome, the Sapotaceae family is categorized as one of the
richest and most diverse in the state of Amazonas, but most studies are concentrated
close to cities, rivers or roads, with repercussions in areas of little sampling. Of this
So the objective of this study is to know the distribution pattern of the samples
collected from Sapotaceae and its wealth for Amazonas and its municipalities, using
data available at the Reflora Virtual Herbarium. For this purpose, the Herbarium database
Virtual Reflora was accessed to obtain data on exsiccates belonging to the
Sapotaceae and collected in the Amazon. Information about the states and
municipalities, in addition to the spelling and synonyms of scientific names. Wealth was quantified and
abundance of genera and species in Amazonas and these data were compared between
Amazonian municipalities. Rarefaction curves were drawn up with the information
of the specimens collected. Through the results provided by the rarefaction curve,
a sample distribution map was elaborated. Based on the number of collections and
its relation with the rarefaction curve of the best sampled municipality, the other
municipalities were classified as well sampled, reasonably sampled and poorly
sampled. After processing the data, 2,318 exsiccates remained, distributed in 11
genera and 148 species. The most abundant genera were: Pouteria, Micropholis and
Chrysophyllum, adding 76% of the samples. The most abundant species were:
Chrysophyllum sanguinolentum and Micropholis guyanensis. Although diversity is
expressive in Amazonas, the number of specimens collected is very concentrated in
Manaus (744 exsiccates), Rio Preto da Eva (609) and São Gabriel da Cachoeira (164)
most abundant municipalities, and consequently the municipalities with the highest
known wealth. These three municipalities were classified as good or
reasonably sampled, while the remaining 95% of the municipalities were
considered poorly collected. Such results show that the state has
it leaves regions of little knowledge about the richness of Sapotaceae. Once
that this family is recognized for being rich and abundant in the Amazon biome, its
small sampling should indicate sampling deficiency in other plant groups
less abundant, revealing a low knowledge of the general flora of the great
most Amazonian municipalities.
