“…This 'nurse effect' is by no means confined to such extreme environments. In chalk grassland in the Netherlands, Car Una vulgaris and Linum catharticum seedlings had lower rates of mortality where bryophyte cover was highest (Keizer, van Tooren & During, 1985) and the establishment of Carduus nutans L. in old fields appears to be facilitated by the mulch formed by litter of Bromus japonicus Thumb. (Lee & Hamrick, 1983).…”

SUMMARYThe factors which cause the death of seedlings were examined and an attempt was made to determine the selective forces to which they are subjected in the field. After briefly dealing with the difficulties of defining a seedling, I examine a few cases from the recent literature in which the causes of seedling mortality are identified and quantified either by monitoring populations under natural conditions or by manipulating the environment experimentally. The special vulnerability of the immediate post-germination phase is illustrated and the consistent underestimation of seedling loss in many studies is suggested. Some interesting cases of the efTects of neighbours on seedling mortality are examined and it is shown that nearest neighbours may affect a seedling's chance of being grazed. It is concluded that since the causes of seedling mortality are so varied and unpredictable in most habitats, individual plasticity may provide a better strategy for survival than highly specialized adaptations to specific mortality factors.

“…Studies on a range of different crust types have found negligible effects of BSCs on seedling germination (Beyschlag et al 2007;Eldridge et al 2000;Keizer et al 1985;Sedia and Ehrenfeld 2003;Li et al 2005;Sylla 1987), while other studies have reported positive effects of crusts on seed germination (Belnap 2002;Kleiner and Harper 1977;Boeken et al 2004;). Previous studies have primarily focused on testing how changes to BSC over time influence seed germination (Langhans et al 2009;Su et al 2007 ), and previous field studies investigating natural dispersal and emergence have generally studied annual, not perennial plant species (Belnap and Harper 2001).…”

“…by Kalinauskaitë & Laaka-Lindberg, 2012) Ingerpuu et al (2005). Increasing ground layer cover increases soil water-holding capacity and thereafter facilitates vascular plant seed germination and seedling establishment, which, however, differs between species (Keizer et al, 1985;Zamfir, 2000). Gradually, as the plant cover begins to settle the ground layer species including terrestrial macro-lichens and bryophytes take over, stabilize the sand and initiate the vegetation development towards pine-dominated forests (see Stankevièiûtë, 2000b).…”

Structural composition of the ground layer vegetation on sandy dunes of the Curonian Spit Nature Reserve, Lithuania, is described. The Curonian Spit is a 98 km long, narrow sandy ridge at the eastern coast of the Baltic Sea, belonging partly to Lithuania and partly to Kaliningrad Province of Russia. The ground layer vegetation structural elements include lichens and bryophytes, with vascular plants representing the field layer. Along the vegetation succession on the grey dunes, the vascular plants dominating in the early stages are substituted by bryophytes and lichens. The bryophytes become dominant towards the late stages of the succession of the ground layer communities. The role of species interactions as regulators of the ground layer vegetation is discussed.
