Kelp versus Coralline: Cellular Basis for Mechanical Strength in the Wave-swept Seaweed Calliarthron (corallinaceae, Rhodophyta)

Previous biomechanical studies of wave-swept macroalgae have revealed a trade-off in growth strategies to resist breakage in the intertidal zone: growing in girth versus growing strong tissues. Brown macroalgae, such as kelps, grow thick stipes but have weak tissues, while red macroalgae grow slender thalli but have much stronger tissues. For example, genicular tissue in the articulated coralli...

Taxonomy of fossil coralline algal species: Neogene Lithophylloideae (Rhodophyta, Corallinaceae) from southern Spain

The anatomy of coralline algae is relatively simple. This, together with high intraspecific variability, reduces characters used as diagnostic criteria in delimiting species in present-day coralline algae to a very few, most of which can be recognized in fossil representatives of this family. Similar taxonomic procedures may thus be used at the species level both in modern and fossil coralline ...

Erodibility of road batters under simulated rainfall

Rainfall simulation experiments on road batters in a forest catchment in New South Wales, Australia, demonstrated the limits of small scale erosion studies. Comparable erodibility studies were carried out on road surfaces, road batters constructed of soil, bedrock and unconsolidated materials and the forest surfaces. There was no significant difference in sediment loss between any type of site,...

A novel training tool for batters to watch the ball

Like a rolling stone: the mobility of maerl (Corallinaceae) and the neutrality of the associated assemblages.

Beds of nonattached coralline algae (maerl or rhodoliths) are widespread and considered relatively species rich. This habitat is generally found in areas where there is chronic physical disturbance such that maerl thalli are frequently moved. Little is known, however, about how natural disturbance regimes affect the species associated with maerl. This study compared the richness, animal abundan...
