“…The continual identification of new species and the high level of endemism detected in other studies reinforce the evidence of the uniqueness of this relatively unexplored region , Thomas et al 1998, Carnaval and Moritz 2008). Of all the coastal areas of Brazil, coastal forests contain the highest number of endemic species of Myrtaceae (15 species), which are threatened with extinction (Carnaval andMoritz 2008, Murray-Smith et al 2008).…”

“…Moreover, the present study aimed to investigate whether these vestigial areas differ in terms of abundance from other areas of vestigial forests located in nearby regions, for which floristic documentation exists. In southern Bahia, the abundance and endemism of vascular plants reportedly yields high levels of diversity (Thomas et al 1998, Martini et al 2007, Thomas et al 2009, Murray-Smith et al 2008. Importantly, this floristic documentation provides more detailed information on the endemism, abundance, areas of occurrence of taxa, and identification of new species and may serve as the foundation for future studies on biome similarities, biogeography, and community structure (Giulietti et al 2005, Funk 2006).…”

The aim of this study is to survey the angiosperms of two montane forest remnants in the southern Bahia, Brazil: Corcovado (SCO) and Pedra Lascada (SPL). Both fragments are located in the municipality of Almadina and Barro Preto, respectively, and are 18 km distant from each other. We sampled 899 species of angiosperms distributed in 437 genera and 116 families. The SCO was the richest area with 678 species, distributed in 367 genera and 100 families. SPL showed 466 species in 269 genera and 88 families. The percentage of species identified was 85.8% and of this total, 37.7% are endemic to the Atlantic Forest, 11.2% are endemic to southern Bahia and northern Espírito Santo and 7% are disjunct between the Atlantic Forest and Amazon. The remaining percentages (44.3%) were of species widely distributed. The richest families in the two areas were Orchidaceae (10%), Rubiaceae (7%), Bromeliaceae (5.5%), Melastomataceae (4.2%) and Poaceae (4%). The richest genera were Psychotria (2%), Piper (1.8%), Ocotea (1.6%), Vriesea (1.5%) and Peperomia (1.4%). More than half of the recorded species showed non-arboreal habit, regarding life forms documented. That comes against the assertion that many authors in the tropical forests, where species richness in angiosperms is expected for non-woody species, especially in montane forests. Twelve species have been identified as new, but seven others already described from collections previously obtained in these two areas. Orchidaceae, Rubiaceae, Poaceae and Bromeliaceae showed significant richness in this study these families are commonly reported as the richest in other inventories in the Atlantic Forest in southern Bahia reinforcing their importance to the regional flora. The high levels of richness, endemism, and the growing numbers of new taxonomic discoveries from the SPL and SCO sites indicate the biological importance of these two forest remnants. The implementation of parks or other protected environmental reserves would be essential to the conservation of its species. www.biotaneotropica.org.br/ v14n1/pt/abstract?inventory+bn00387812014Resumo: O presente estudo objetivou inventariar as angiospermas de dois remanescentes florestais no sul da Bahia, Brasil.

“…In other studies in the Atlantic Forest, sites situated in different forest patches, even with urban matrix among them (Nemésio andSilveira, 2007a, 2010), presented similarities higher than those presented here. Also, sites sampled at the same forest patch in other studies (e.g., Tonhasca Junior et al, 2002;Nemésio and Silveira, 2006) showed higher similarities. On the other hand, the overall similarities reported here are similar to those found among sites at the nearby 'Reserva Biológica de Una' (Nemésio, 2013).…”

“…marianae at REV is remarkable, because it is the smallest forest patch where this species was ever found, together with 'Estação Ecológica (ESEC) de Murici', in Alagoas (Nemésio, 2010b). As happened at ESEC Murici, the population of this species seems to be very tiny at REV and the only two recorded males were collected at the site in the interior of the forest, as usually preferred by this species (see Tonhasca Junior et al, 2002;Nemésio and Silveira, 2006).…”

“…The region of the southern state of Bahia and northern state of Espírito Santo, known as 'Hileia Baiana', holds one of the most diverse and rich biotas in the planet (Myers, 1988;Mittermeier et al, 1999;Galindo-Leal and Câmara, 2003;Laurance, 2009), with high levels of endemism for many taxonomic groups (e.g., Dean, 1995;Pacheco et al, 1996;Thomas et al, 1997Thomas et al, , 1998Sambuichi et al, 2008). Nonetheless, except for two unpublished studies carried out in the region (BonillaGómez, 1999;Melo, 2005), the orchid-bee fauna of 'Hileia Baiana' remained virtually unknown until now.…”

The orchid-bee faunas of the 'Parque Nacional do Pau Brasil' (8,500 ha) and 'RPPN Estação Veracel' (6,000 ha), two Atlantic Forest remnants in the southern state of Bahia, northeastern Brazil, were surveyed. Seventeen chemical compounds were used as scent baits to attract orchid-bee males. Seven hundred and twelve males belonging to 20 species were actively collected with insect nets during 80 hours in February and April, 2009. Euglossa marianae Nemésio, 2011, the most sensitive orchid-bee species of the Atlantic Forest, was recorded at both preserves, though in low abundance. 'RPPN Estação Veracel' is the smallest forest patch where Euglossa marianae has ever been recorded.Keywords: Atlantic Forest, conservation, Euglossina, euglossine bees, Hexapoda. As faunas de abelhas-das-orquídeas (Hymenoptera: Apidae) de dois remanescentes de Mata Atlântica do sul da Bahia, leste do Brasil ResumoAs faunas de abelhas-das-orquídeas do Parque Nacional do Pau-Brasil (8,500 ha) e da RPPN Estação Veracel (6,000 ha), dois remanescentes de Mata Atlântica no sul da Bahia, Nordeste do Brasil, foram amostradas. Dezessete iscas atrativas a machos de abelhas-das-orquídeas foram utilizadas. Setecentos e doze machos pertencentes a 20 espécies foram coletados com o uso de redes entomológicas durante 80 horas, em fevereiro e abril de 2009. Euglossa marianae Nemésio, 2011, a espécie de abelha euglossina mais dependente de ambientes florestais, foi registrada nas duas áreas, embora pouco abundante. A RPPN Estação Veracel é a menor área onde essa espécie já foi coletada.Palavras-chave: Mata Atlântica, conservação, Euglossina, abelhas euglossinas, Hexapoda.

Secretory structures in plants play a crucial role in producing bioactive compounds. Despite the potential of the Swartzia genus, comprehensive studies in this context are still scarce. Swartzia is a legume tree (Fabaceae) that occurs in the Brazilian Atlantic Forest, a biodiversity hotspot, and includes species such as Swartzia flaemingii. Therefore, we aim to achieve: (1) identify and characterize the key secretory sites responsible for saponin production in S. flaemingii leaflets; (2) confirm the presence of saponins in S. flaemingii leaves by comparing them with known chemical profiles of other Swartzia species; (3) assess the potential hemolytic and cytotoxic effects of crude leaf extracts. Our investigation unveils the presence of phenolic idioblasts, mucilage cells, and articulate laticifers, which play pivotal roles in defense and adaptation. Notably, we report the first‐ever ultrastructural details of laticifers in a legume species. Additionally, oleanane‐type saponins were identified in the leaves, giving insights about the chemotaxonomic profile of Swartzia. The crude extracts show low cytotoxicity levels, showcasing as a promising alternative source of saponins. This investigation reinforces the importance of conserving plants in threatened regions like the Atlantic Forest, a global biodiversity hotspot facing substantial anthropogenic pressures.
