Pollen production of Chenopodiaceae species at habitat and landscape scale in Mediterranean salt marshes: An ecological and phenological study

Modern pollen and non-pollen palynomorph assemblages of salt marsh and subtidal environments from the Ría de Vigo (NW Iberia)

“…Usually, this plant colonizes channel and creek banks (Beeftink et al, 1978), where sediments (and palynomorphs) tend to accumulate because of the reduction in water speed. Also, the high pollen productivity of Chenopodiaceae (Fernández-Illescas et al, 2010) causes the decrease in regional pollen percentages in the pollen record of the sediments. The Unidentified non-septate filamentous algae present in H. portulacoides patches (Fig.…”

Pollen production in halophytic species of the Chenopodiaceae in a Mediterranean marsh

“…According to Cruden (2000), this might be related to population densities: pollen production is usually higher for species in which the individuals grow as a rule at larger distances from each other. In agreement with their relatively low pollen production, the Sarcocornia species grow in highly restricted habitats with extensive coverage and little diversity (Fernández-Illescas et al, 2010a). Sarcocornia perennis occupies the lower levels of the salt marshes, where it acts as a coloniser (Davy et al, 2006) and dominates the Pucinellio maritimae-Arthrocnemetum perennis (RivasMartínez et al, 1980) community.…”

“…Both localities 1 and 2 consist of similar vegetation complexes as indicated by Fernández-Illescas et al (2010a). The lower zone is completely submerged at high tide and consists only of Sarcocornia perennis (Pucinellio maritimae-Arthrocnemetum perennis Géhu, 1976).…”

Reproductive phenology and pre-dispersal fruit predation in Atriplex halimus L. (Chenopodiaceae)

“…This population grows on a saline soil island surrounded by a tidal marsh in a virtually monospecific shrub community (37°13’53”N 6°57’50”W). See Fernández-Illescas et al (2010) for cover values. This location has a typical Mediterranean climate with an average annual temperature of 18.0°C and an average annual rainfall of 460.9 mm, calculated from data recorded at the Moguer Meteorological Station, 12 km from the location (Rivas-Martínez and Rivas-Sáenz 1996–2009) (Figure 1).…”
