“…Thus, the primary high estimates of species diversity for the inspected benthic (epiphytic) diatom assemblages of the RA may reflect the pristine conditions of the islands due to the combined factors of remoteness and enforced policies as a protected natural area. When compared to diversity values from other protected areas, such as the Guerrero Negro lagoon, certain equivalence is noted with the average values of H = 4.96 bits/taxon, and range of 3.7-5.9, computed for the epipelic diatom assemblages of that lagoon [3]. So, according to the latter study, the high values of diversity depict pristine or undisturbed conditions (independent of whether the habitat is protected or not), but species richness and the corresponding diversity values are expected to be as high as those in both studies.…”

“…Thus, both diversity and ecological aspects of benthic diatoms should be considered essential in order to have an adequate ecological prospect of any aquatic ecosystem, particularly when developing management plans for protected areas. The high floristic potential of benthic diatoms (Bacillariophyceae) for Mexican littorals has recently been confirmed through surveying new substrata and by studies in hitherto unexplored areas that have yielded numerous new records for the region [3][4][5][6][7] and have enriched the overall species list for the region [6]. According to [8], in some parts of the biosphere where diatoms are abundant, there is very little known about them.…”

“…To determine spatial and temporal environmental health in Kusrüpuyewe Lake, alpha and beta diversities were used in this study. Alpha diversity was obtained using the Chao-1 species richness estimators and Shannon index; we consider a Shannon index of H ′ > 2.6 bits/ind high for phytoplankton assemblages [39]. Alpha diversity indicated spatial and temporal ecosystem stability [40].…”

“…Said ecological studies are to be based on analyses of classical parameters that can reflect undisturbed environments or reflect various types of impact (Magurran, 1998). Thus, unlike species richness alone, analysis of species diversity depicts a structure in benthic diatom assemblages based on composition, relative abundance, diversity, equitability, and dominance, which can be used to assess environmental conditions in protected areas (Siqueiros-Beltrones et al, 2017). Notwithstanding, floristics still constitutes the primary basis to achieve it, inasmuch it constitutes the main reference for the occurrence of indicator species in a given locality that help to infer appropriate conditions for their presence.…”
