The Bryologist, 1926
For years I have been on the watch for an opportunity to observe the explosive distribution of Sphagnum spores as described by Goebel, always supposing that the observations must be made in the field. Early last spring at Manatee, Florida I collected a fine lot of Sphagnum strictum in perfect fruit, 95% of the capsules full, round, black and operculate.

Dispersal of spores following a persistent random walk
Physical Review E, 2003A model of a persistent random walk is used to describe the transport and deposition of the spore dispersal process. In this model, the spore particle flies along straight line trajectories, with constant speed v, which are interrupted by scattering, originating from interaction of spores with the field and wind variations, which randomly change its ...

Spore Dispersal Distances in Atrichum angustatum (Polytrichaceae)
The Bryologist, 1992Spores released from two colonies of Atrichum angustatum (Brid.) Bruch & Schimp. in B.S.G. in North Carolina were sampled within a 15-m radius of each colony to determine the scale and pattern of dispersal. The density of recovered spores decreased inversely with increasing height and distance from the center of each colony.

Dispersal of Riella Spores by Waterfowl
The Bryologist, 1961There are at present no major lake basins in the Panhandle and South Plains region of the state, but rain can and does collect in numerous of the locally depressed areas, forming "playa lakes." At such a lake, 13.5 miles east and 10 miles north of Lubbock, Lubbock Co., approximately 15 gallons of almost pure material were collected on October 11, 1960.

Spore Dispersal in Chaetomium globosum (Kunze)
Nature, 1961IN the genus Chaetomium the fruit-body, a perithecium, is ornamented with a large number of apical hairs which are either spirally coiled or dichotomously branched. The ascospores are released within the perithecium by breakdown of the ascal walls and the spores ooze out of the ostiole and either form a spore tendril or become entrapped in the apical ...

Spore Liberation and Dispersal in Smut Fungi*
Botanica Acta, 1998Abstract:Teliospores are the most important diaspores of smut fungi, albeit not the only ones. The role of basidla, basidiospores, secondary spores, yeast cells, and infected parts of the host for dispersal has often been neglected. Many smut species have soral structures like galls, peridia, and elaters, which cause teliospores to be liberated over ...

Notes on Spore Dispersal in Sphagnum
The Bryologist, 1907E. J. WINSLOW. On August gth of the present year, while botanizing in a swamp near Lake Willoughby, Westmore, Vt., my attention was attracted by the frequent recurrence of a snapping sound like the breaking of a wheat straw. Upon investigation I found that the Sphagnum, which grew abundantly all around, was heavily fruited, and the strongly inflated ...

Modeling spore dispersal in a barley crop
Agricultural Meteorology, 1982Abstract A model of aerial spore transport by Legg and Powell (1979) is modified here to account for passive liberation of spores by wind and its effect on the subsequent transport and deposition of spores within the crop. Spores blown from surfaces by wind are removed mainly during gusts when the wind speed exceeds a threshhold value characteristic ...
