“…Escudero et al (2007) and Serpe et al (2008) showed that BSC reduced seedling emergence when it was dominated by species like Diploschistes sp., because this lichen might seal the soil, thus reducing water availability during the germination period of some plants (Otsus and Zoel, 2004;Morgan, 2006). Contrastingly, the presence of both algal and moss crusts significantly enhanced the germination of Bassia dasyphylla (Fisch.…”

Effect of biological soil crusts on the germination of three plant species under laboratory conditions

Semiarid grasslands in northeastern Mexico contain endemic plants and animals, and are an important refuge for resident and migratory animals. Here, as in other semiarid areas, biological soil crusts (BSC) are a key component of the ecosystem. However, fi ndings about their effect on the germination of vascular plants are contradictory. We asked whether seed germination of some native plant species would be inhibited by the presence of BSC as it has been found in other studies; in turn, we evaluated the effect of fi ve lichens (Endocarpon pusillum Hedw., Placidium sp., Psora cerebriformis W.A.Weber, Psora decipiens (Hedw.) Hoffm., Xanthoparmelia chlorochroa (Tuck.) Hale), one cyanobacteria (Nostoc commune Vauch.), and one hepatic (Oxymitra sp.), from the dominant BSC of the area on the germination percentage (germinability) and speed of germination (t 50 ) of three native plant species: Frankenia gypsophila I.M.Johnst., Muhlenbergia arenicola Buckl., and Sartwellia mexicana A.Gray. Germination tests were carried out in an environmental chamber at 26 °C and at a constant humidity of 60% with 12:12 hours light and darkness. BSC did not affect germination percentage of the three evaluated plant species when compared to bare soil. Speed of germination ranged between 3.5 and 5 days and there were no differences between substrates. Keywords: Endocarpon pusillum, northeastern Mexico, Nostoc commune, Placidium, semiarid grasslands.Resumen: En los pastizales semiáridos del noreste de México se encuentran plantas y animales endémicos, y son un refugio importante para animales residentes y migratorios. Aquí, como en otras zonas semiáridas, las costras biológicas del suelo son un componente clave del ecosistema. Sin embargo, los reportes sobre su efecto en la germinación de plantas vasculares son contrastantes. En este trabajo se investiga si la germinación de algunas especies de plantas nativas sería inhibida por la presencia de costras biológicas del suelo como se ha encontrado en otros estudios, y se evalúa el efecto de cinco líquenes (Endocarpon pusillum Hedw., Placidium sp., Psora cerebriformis W.A.Weber, Psora decipiens (Hedw.) Hoffm., Xanthoparmelia chlorochroa (Tuck.) Hale), una cianobacteria (Nostoc commune Vauch.) y una hepática (Oxymitra sp.), que son componentes de las costras biológicas del suelo dominantes en el área. Los efectos evaluados son en el porcentaje (germinabilidad) y rapidez de germinación (t 50 ) de tres especies de plantas nativas del área: Frankenia gypsophila I.M.Johnst., Muhlenbergia arenicola Buckl. y Sartwellia mexicana A.Gray. Las pruebas de germinación se realizaron en una cámara ambiental a 26 °C, humedad constante del 60%, 12:12 horas luz: oscuridad. Las costras biológicas no afectaron el porcentaje de germinación de las tres especies de plantas evaluadas comparado con el suelo desnudo. La rapidez de germinación estuvo entre 3.5 y 5 días, sin diferencias entre los sustratos. Palabras clave: Endocarpon pusillum, noreste de México, Nostoc commune, pastizales semiáridos, Placidium.

“…reduced plant emergence (Escudero et al, 2007;Serpe et al, 2008). This might be due to the sealing of the soil pores by these crusts that might reduce water availability and thus inhibit germination (Eldridge et al, 2010).…”

“…The fruit is an ovoid-globose and hairy capsule with ovoidcompressed, smooth, and brownish. This is a chaméphyte (Escudero et al, 2007), family of Cistaceae, arid regions and semi-arid areas (Perez-Garcia and Gonzalez-Benito, 2006). Despite its ecological and economic interests, this plant is a rare endemic flora of the western basin of the Mediterranean (Escudero et al, 2007), as a result of overgrazing (Aidoud et al, 2006).…”
