“…The saltmarshes are discontinuously distributed across the region resulting from variation in topography and the duration of saltwater submersion (Costa et al 2003). The main saltmarshes are dominated by Spartina densiflora and Salicornia neei; S. neei is dominant in sites with longer periods of inundation and higher salinities (Costa 1997;Costa et al 2019). Small islands have formed in the central and southern portions of the lagoon, comprised mostly of saltmarshes along their borders (Costa & Tagliani 2011) and low grasslands in their interiors (~5 cm height, F.A.…”

Breeding habitats, phenology and size of a resident population of Two‐banded Plover (Charadrius falklandicus) at the northern edge of its distribution

The central‐peripheral hypothesis states that the demographic performance of a species decreases from the centre to the edge of its range. Peripheral populations are often smaller and tend to occur under different and suboptimal conditions from those of core populations. Peripheral populations can also coexist during part of their annual cycle with populations from the core of the species’ range. Studies on peripheral populations are thus valuable for broadly understanding ecological and evolutionary processes. The Two‐banded Plover (TWBP, Charadrius falklandicus, Charadriidae) is an endemic South American shorebird that breeds in Argentine and Chilean Patagonia and migrates northward during the Austral winter. There are breeding records, however, from Lagoa do Peixe National Park in southern Brazil. In this study, we (i) mapped TWBP nests, (ii) characterised their reproductive biology and nesting habitats, (iii) colour‐marked birds and evaluated their seasonal occurrence patterns and (iv) estimated the size of the Brazilian population by combining supervised habitat classification analyses and generalised additive models. We estimated that the Brazilian population has 55 (95% CI: 44.1–66.6) breeding pairs and found that the length of their breeding season was roughly 5 months, spanning the Austral spring and summer. The population’s nesting habitat differed, and their apparent reproductive success was lower than that of core populations. Unlike more southerly populations, the results of our mark‐resighting efforts demonstrate that the Brazilian population is sedentary. Taken together, these results indicate that the Brazilian TWBP population seems geographically isolated from the species’ southernmost core populations, resulting in a heteropatric distribution. Furthermore, differences in nesting habitat and year‐round residency indicate that this peripheral population is ecologically distinct. The marked behavioural and ecological differences combined with the small population at the northern edge of the TWBP distribution support the central‐peripheral hypothesis in a Neotropical system.

“…Crespo, Salicornia gaudichaudiana Moq. ; COSTA et al, 2019). This plant is sold as "sea asparagus" or "samphire" and used as a fresh vegetable in gourmet kitchens, in the industrial sector (e.g., pickles, salami, beer and biosalt), and for animal food (COSTA;HERRERA, 2016;ALVES et al, 2019).…”

“…Two lineages (BTH1 and BTH2) with contrasting prostrate and decumbent plants with green and reddish colorations, respectively, were obtained. Recent studies confirmed that these lineages show distinct genetic (COSTA et al, 2019), mineral (DONCATO; COSTA, 2018a; 2018b) and phenolic compositions (SOUZA et al, 2018). However, plant field trials are needed to evaluate how cultivation conditions affect growth and desirable agronomic traits of these lineages.…”

A Salicornia neei é utilizada como vegetal fresco em cozinhas gourmet e alimentos industrializados, bem como na alimentação animal. Este trabalho teve como objetivo avaliar o efeito de diferentes regimes de irrigação de água salina sobre o crescimento vegetativo de progênies F3 e F4 de novas linhagens de S. neei (BTH1 e BTH2). Vinte plantas por progênie foram irrigadas com 375 L de água salina da carcinicultura a cada dois (T2) e quatro (T4) dias em canteiros. Esses esquemas de irrigação foram quantificados como 249% e 151% do potencial de evapotranspiração estimada do período de estudo (670 mm), respectivamente. Os dados foram analisados por ANOVA. BTH2-F4 exibiu o melhor desempenho vegetativo e uma biomassa média da parte aérea fresca de 201,2 ± 17,1 g. O tempo médio para o início da floração foi mais cedo e o investimento em estruturas reprodutivas foi maior (representando 54-62% da biomassa total da parte aérea) para as progênies BTH1 do que BTH2 (14,6-16,7 semanas; 26-42% da biomassa total da parte aérea). A irrigação a cada quatro dias beneficiou a altura dos caules e atrasou o florescimento de ambas as linhagens, mas não afetou a produção de biomassa da parte aérea. Em conclusão, as plantas BTH2-F4 apresentaram melhor desenvolvimento entre as progênies e maior altura do caule sob irrigação a cada quatro dias.

Este estudo objetivou avaliar o crescimento e o ganho de biomassa de Salicornia neei Lag. em cultivo irrigado com água salobra no semiárido cearense. Foram testados quatro tratamentos (T1, T2, T3, T4) aos 15, 30, 45, 75, 90 e 105 dias após estabilização (DAE) em duas safras. T1 e T2 receberam uma, e T3 e T4 duas irrigações ao dia (30 minutos) e apenas T2 e T4 foram adubadas. As taxas de crescimento absoluto (TCA) em T1 e T2 diferiram na 1ª (75 DAE) e 2ª safras (15 e 30 DAE), já T3 e T4 não diferiram nas duas safras. Na 1ª safra, a taxa de crescimento relativo (TCR) das plantas em T1 diferiu de T2 aos 15 DAE, e T3 diferiu de T4 aos 45 DAE. Na 2ª safra as TCR em T1 e T2 diferiram aos 15, 30 e 45 DAE, e T3 e T4 não diferiram. As massas fresca e seca produzidas nas duas safras foram respectivamente: T1
