“…In their study, Costa and Herrera (2016) observed that S. galheirensis and four other species of the Malvaceae family (Herissantia crispa (L.) Brizicky, H. tiubae, Sida cordifolia L. and Melochia tomentosa L.) as being well adapted to colonize degraded areas in the caatinga. The data observed for Fabaceae 1, as it is a species belonging to one of the most varied families in the phytogeographic domain of the Caatinga, has a richness and diversity often related to efficiency in association with nitrogen-fixing bacteria and morphological, physiological, and agroecological adaptations to inhabit both temperate and tropical climates (LPWG, 2017).…”

The objective was to evaluate the structure of the young regenerating stratum in a degraded riverside area of caatinga in the Serra Branca-PB, the semiarid region of Paraíba. Two inventories were performed, one in the dry season (September/2019) and the other in the rainy season (March/2020). In the riparian area, 50 contiguous plots of 10 X 20 m were allocated. In the center of each plot, subplots of 1 X 1 m were plotted, totaling 50 m2, for the evaluation of the regenerating stratum. The density, frequency, dominance, and importance value parameters were calculated. The heterogeneity of the floristic community was determined by the Shannon diversity index (H') and Pielou's evenness index (J'). In both inventories, 39 species distributed in 31 genera and 14 families were recorded. In the dry period, the species with the highest importance value were respectively Alternanthera tenella Colla, Sida galheirensis Ulbr. and Fabaceae 1. Related to the rainy season, the species with the highest importance value were Urochloa decumbens (Stapf), R.D.Webster, Blainvillea acmella (L.), Philipson, and Boerhavia diffusa L. The diversity and evenness values were 1.22 nats.ind.-1 and 0.49 (dry season) and 2.59 nats.ind.-1 and 0.71 (rainy season), respectively. The results obtained in the two inventories were similar to other studies in these same conditions of degraded caatinga. The study also demonstrated that this area is in an initial stage of ecological succession, with a predominance of exotic species in both inventories (dry and rainy).

“…Salt flats are basically hypersaline areas that have thin salt encrustation at the surface. They occur widely in different ecological expanses of the world and represent a lot of floral and faunal diversity (Costa and Herrera 2016). Halophytes coincidentally are the only plants, which can successfully perpetuate and survive in such type of hypersaline habitats in nature.…”

Halophytes constitute a fascinating group of higher plants which exhibits unique morphological, anatomical, and physiological adaption in order to perpetuate and survive in highly saline conditions. India has significantly large extend of saline land under coastal and inland regions where both the natural and anthropogenic practices resulted in extensive salt flats. The coastal salt flats are distributed irregularly over the East and West coast. Salinity is due to abundance of NaCl and Na 2 SO 4 salts and reaches up to 70 dS m À1 EC values during the summer. The dominant vegetation cover includes true halophytes (Sesuvium spp., Suaeda spp.), seagrasses (Ruppia spp.), and mangroves (Avicennia spp., Rhizophora spp.). Such halophytic life forms are imperative for the estuarine food web and typically used by the local inhabitant for food, fodder, fuel and fiber production.

“…The small succulent shrubs with leafless stems and branches of the genera Salicornia L. and Sarcocornia A.J.Scott (Salicornioideae, Amaranthaceae) are characterized as "extreme halophytes" based on their ability to thrive in seawater-flooded and hypersaline soils (Davy et al 2006;Steffen et al 2015). These halophytes have been consumed by humans for centuries, and to date are cultivated with a broad range of saline water sources and sold as 'sea asparagus' or 'samphire', particularly used as functional gourmet food, animal feed meal and oils for biodiesel (Ventura & Sagi 2013;Ventura et al 2015;Costa & Herrera 2016).…”

“…The morphological identification of dried herbarium specimens can be very difficult, and the Brazilian coast represents a biogeographic gap in molecular studies of Salicornioideae in Americas. The Brazilian sea asparagus of the genus Salicornia shows a recent history of successful cultivation with saline water and shrimp farm effluent (Costa & Herrera 2016), high nutritional quality (Bertin et al 2014;Costa et al 2014) and chemical characteristics for biofuel production (D'Oca et al 2012;Costa et al 2014). However the designation of plants found in Brazil as Salicornia ambigua (=Sarcocornia ambigua) is uncertain.…”

Molecular markers indicate the phylogenetic identity of southern Brazilian sea asparagus: first record of Salicornia neei in Brazil

Molecular phylogenetic analyses based on ETS, ITS and atpB-rbcL spacer sequences assessed the phylogenetic status of the southern Brazil sea asparagus species of the genus Salicornia (Salicornioideae, Amaranthaceae). Accessions of Patos Lagoon estuary (32° S) were obtained from wild plants and two pure line lineages, selected from contrasting prostrate (BTH1) and decumbent (BTH2) ecomorphotypes found locally. Patos Lagoon wild plants, BTH1 and BTH2 f4 progenies showed 100% identical sequences for the atpB-rbcL and ITS spacers, only two mutations for ETS. Comparison of the sequences of these three markers with GenBank records confirmed the identity of Brazilian accessions as Salicornia neei. Maximum-likelihood phylogenetic analysis of ETS sequences indicated that the southern Brazilian accessions of Salicornia certainly are not close to any of the Salicornia ambigua accessions in GenBank, which are restricted to the northern hemisphere, nor are they related to any Salicornia fruticosa/Salicornia perennis clade accessions, which are also restricted to Eurasia. All above cited species have been wrongly applied to the southern Brazil sea asparagus.
