“…Hypothesis 2: the identity of each sub-area is derived from spurious processes, such as bioinvasions (e.g., human mediated) that are currently being examined (e.g., Bardi & Marques 2009;Rocha et al 2013). If so, these sets of sub-areas would not be historical areas per se.…”

Geographic distributions of 130 species of benthic hydroids were used to infer areas of endemism in the Southwestern Atlantic Ocean (SWAO, between 22°S and 55°S). Endemicity Analysis (EA) was carried out with the software NDM VNDM, using a 2° x 2° grid with different values of F (F = 0.5 and F = 1.0) for inferred presence. Hypothesized areas of endemism (16 with F = 0.5 and 13 with F = 1.0) formed three generalized patterns: (1) Tropical, (2) Subtropical, and (3) disjunctions along Tropical and Subtropical areas. Areas of endemism estimated here were compared with provinces, ecoregions and areas of endemism previously defined (but not based on algorithmic analysis) in the literature. Ecological and historical aspects that are potentially relevant for the SWAO realm were contrasted, related and discussed to areas of endemism. This is the first study to apply NDM VNDM to the marine realm and one of the few that focuses on the SWAO.

“…ROCHA et al (2013), however, listed 15 species as cryptogenic, and it is probable that this number reflects an insufficient effort to get to know the bryozoan fauna, especially in the northeast (VIEIRA et al 2008), limiting the ability to detect new arrivals, as it has been the case with ascidians ). Owing to the potential ecological impact of T. arcuatum on coastal community structure and function, as already noted for Tubastrea spp.…”

“…Together with air and sea surface temperature, other local environmental conditions vary somewhat between these sites, such as precedence of water masses, water turbidity, distance from (Table I), but these might have relatively minor direct effects on assemblage richness patterns, especially when compared to broader-scale factors, such as temperature, climate and regional richness. Both sites are surrounded by natural habitats and at least for cnidarian assemblages, this is indicated by the rarity of exotic cnidarian species (Rocha et al 2013).…”

An important component of species diversity which has recently received significant attention is the change in species composition across space, or beta diversity. Temporal turnover of species is an equally important component of species diversity, which can by itself account for diversity patterns, but has received much less attention, especially in marine communities. Indeed, patterns of diversity of marine epifaunal assemblages may be better understood through the study of variability in richness and composition of recruits that colonize and survive long enough to start a population, but before species interactions mask the diversity initially settled. Here we document temporal patterns in richness and composition of recruits of a speciose benthic cnidarian assemblage, contrasting a tropical and a subtropical site to evaluate simple predictions about latitudinal diversity and richness stability. Recruitment variation was quantified during five three-month periods at two harbour areas (Pecém at 3°32′S and Ilhabela at 23°46′S) in Brazil separated by 20°latitude. Results show that: (1) species richness of benthic cnidarian assemblages was higher at the more tropical location, as expected from general patterns in marine species global distribution; (2) contrary to the expectation of a negative association between richness and species turnover, temporal turnover of species was similar at both sites, although more seasonal at the higher latitude site; and (3) species temporal persistence was greater at the subtropical site. Results are discussed in the context of how different environments and different regional richness may influence temporal patterns in species turnover and local richness, and how this may vary across latitudes.
