Abstract. This study compiled available information on the dispersal distance of the propagules of benthic marine organisms and used this information in the development of criteria for the design of marine reserves. Many benthic marine organisms release propagules that spend time in the water column before settlement. During this period, ocean currents transport or disperse the propagules. When considering the size of a marine reserve and the spacing between reserves, one must consider the distance which propagules disperse. We could find estimates of dispersal distance for 32 taxa; for 25 of these, we were also able to find data on the time the propagules spent dispersing. Dispersal distance ranged from meters to thousands of kilometers, and time in the plankton ranged from minutes to months. A significant positive correlation was found between the log-transformed duration in the plankton and the log-transformed dispersal distance (r ϭ 0.7776, r 2 ϭ 0.60, df ϭ 1, 25, P ϭ 0.000); the more time propagules spend in the water column the further they tend to be dispersed. The frequency distribution of the log-transformed dispersal distance is bimodal (kurtosis ϭ Ϫ1.29, t ϭ Ϫ4.062, P Ͻ 0.001) with a gap between 1 and 20 km. Propagules that dispersed Ͻ1 km spent less time in the plankton (Ͻ100 h), or if they remained in the plankton for a longer period, they tended to remain in the waters near the bottom. Propagules that dispersed Ͼ20 km spent more than 300 h in the plankton. The bimodal nature of the distribution suggests that evolutionary constraints may reduce the likelihood of evolving mid-range dispersal strategies (i.e., dispersal between 1 and 20 km) resulting in two evolutionarily stable dispersal strategies: dispersal Ͻ1 km or Ͼϳ20 km. We suggest that reserves be designed large enough to contain the short-distance dispersing propagules and be spaced far enough apart that long-distance dispersing propagules released from one reserve can settle in adjacent reserves. A reserve 4-6 km in diameter should be large enough to contain the larvae of short-distance dispersers, and reserves spaced 10-20 km apart should be close enough to capture propagules released from adjacent reserves.

“…Latitudinal differences in reproductive seasonality have been observed over species distribution ranges. For instance, in S. muticum, reproduction starts earlier and lasts longer towards the southern end of the distribution (Norton & Deysher, 1989;Yoshida, 1983;Espinoza 1990). Similarly, shallow water populations of S. polyceratium in Florida reproduced only in winter and early spring (Prince, 1980), whereas reproduction continued throughout the year at Curac¸ao.…”

Sargassum polyceratium is widely distributed around the island of Curac¸ao (Netherlands Antilles) where it inhabits strongly contrasting habitats. Changes in population structure have been followed in three bays with increasing levels of wave exposure at two depths: shallow (0 m) and deep (18 m). The effects of increasing wave exposure were investigated by studying three deepwater populations; and the effects of depth by studying shallow-and deep-water populations in the two calmer bays. Total density and stage density (reproductive thalli, juvenile thalli) were determined and total and individual thallus biomass was estimated non-destructively. In the most wave-exposed deep-water population thalli were twice as long with more than twice the biomass than in the calmest deep-water population. Total density and juvenile density were highest in the bay with intermediate wave exposure. Depth was an important factor at both the individual and population level. Shallow-water thalli had basal holdfast areas that were four times larger than those from deep water, and thallus biomass was positively correlated with holdfast area. Shallow-water juveniles invested more in the development of a holdfast and lateral growth than deep-water juveniles. Total biomass per quadrat was up to 10-fold higher in shallow-than in deep-water populations. In shallow-water populations reproductive thalli were present throughout the year whereas in deep-water populations they were present only during autumn and winter. We conclude that both wave exposure and depth affect population structure. Thalli were generally bigger and total biomass higher in the more exposed bay(s) and in shallower water, contradicting the general pattern in macroalgae of reduced size and biomass with increasing wave exposure.

Sargassum muticum (Fucales: Sargassaceae) has been present in Scandinavia since 1984. In Limfjorden, a shallow Danish sound, it has invaded the habitat of the indigenous Halidrys siliquosa (Fucales: Cystoseiraceae). Studies have suggested a displacement of indigenous relatives by Sargassum muticum and that this could be due to differences in life history strategies. Our study is the first to document the phenology of S. muticum at the northern part of its European distribution range (Scandinavia) and the first to document the phenology of Halidrys siliquosa. Thallus height and weight, species cover and tissue carbon, nitrogen and phosphorus were measured. For Sargassum muticum a strong seasonality with midsummer maxima, similar to previously published results from other European sites, was found. Halidrys siliquosa only exhibited moderate seasonality, if any. Hence, the two species were found to be functionally different and have different life histories. Our results support the idea that the competitive success of Sargassum muticum is caused by its pseudo-perennial life history compared to the truly perennial life histories of many indigenous relatives. Conversion factors between commonly used biometric measures were derived from the phenological data.
