Abstract: This work presents a checklist of the Bromeliaceae in Serra do Conduru State Park (PESC), in the Atlantic Forest of the state of Bahia, Brazil, including data on their growth habit, endemism and conservation status. We also describe and illustrate a new species, Aechmea urussucensis, that is endemic to the area studied and classified by us as critically endangered. The data were collected through field expeditions, analysis of herbarium material and review of the specialized literature. We found 70 species of Bromeliaceae distributed in 20 genera of the subfamilies Bromelioideae (48 spp.) and Tillandsioideae (22 spp.). The diversity of Bromeliaceae in the PESC is the greatest recorded to date in a conservation unit or forest fragment in Brazil. The species studied have a variety of life forms, with 52 spp. being exclusively epiphytic, 7 terrestrial and 11 species occurring in either of these forms. With regard to conservation status, four species are classified as critically endangered, nine as endangered and seven as vulnerable according to the IUCN criteria. In relation to endemism, 33 species are endemic to Bahia (47%), more specifically 31 spp. to the southern region of the state, and three species are microendemic (Aechmea urussucensis, Lymania languida and Wittmackia conduruensis) so far only observed within the PESC. Our results demonstrate that the southern region of Bahia has high diversity in comparison with other regions of the state and also of Brazil. These findings also reveal the scientific value of the PESC and the need for further research conservation and efforts of this region.

The steady increase in cadmium (Cd) levels in the environment from anthropogenic actions has contributed to environmental degradation. Virola surinamensis is a forest species that has desirable characteristics such as deep and dense roots, relatively rapid growth and high biomass production to remedy contaminated environments by Cd. The aim of this study was to assess the physiological responses and the phytoextraction and tolerance capacity of young plants of V. surinamensis submitted to Cd concentrations. The experimental design was a completely randomized design with five Cd concentrations (0, 15, 30, 45 and 60 mg L−1) for 60 days. Leaf water potential (Ψpd), stomatal conductance (gs) and transpiration (E) reduced in plants exposed to Cd. Lower values of maximum photochemical efficiency of photosystem II (Fv/Fm), electron transport rate (ETR) and photochemical quenching coefficient (qP) were accompanied by reduction of photosynthesis (A) with increasing concentrations of Cd, although the non-photochemical quenching coefficient (NPQ), and intercellular CO2 concentration (Ci) showed increase. Instantaneous water-use efficiency (A/E), net photosynthesis to intercellular CO2 concentration ratio (A/Ci) and total chlorophyll (Chl) reduced with increasing levels of Cd. Cadmium concentrations increased in different plant tissues (root > stem > leaf). The tolerance index (TI) indicated that V. surinamensis presented medium and high tolerance to Cd. The results of bioconcentration factor (BCF) and translocation factor (TF) showed low plant efficacy in Cd phytoextraction and suggest that V. surinamensis may be promising for phytostabilization of Cd.
