Aim Estuaries are common focal points for industry and development, but often little is known of their biology or ecology, particularly for sessile taxa. We sought to examine how size and opening regime of shallow saline coastal lakes altered pattern

We investigate the two-point averaging over space of fluctuations arising from a multiscale hierarchy of interacting particles. We assume this will satisfy a condition of homogeneity with respect to scale. We consider the second-order correlation of

The starvation time, optimal initial feeding time, stocking density, and food density were defined for larval red drum (Sciaenops ocellata) in 20- and 40-liter tanks. When larvae were not offered food by the fourth day after eye pigmentation (fifth d

Vitellogenesis, culminating in spawning, was artificially induced in red drum (Sciaenops ocellata) using photoperiod and temperature as exogenous stimuli. Maturation was induced out of season during the normal refractory period of red drum found in c

The hornfelsed Skiddaw Slates in the River Caldew, Cumberland, exhibit one of the best displayed sets of folds in the country. Patterns resulting from an analysis of these folds and the structures on the valley sides, indicate that the rocks have suf

Four phases of deformation (D1-D4) and a ubiquitous non-tectonic bedding-cleavage are described. D1 structures are gravity collapse folds without an associated cleavage, formed before the extrusion of the Borrowdale Volcanics. Pre-Bala folds recognis

Estuaries worldwide are under increasing threat from human impacts. Because much of their fauna remains unstudied and in many cases undescribed, these systems present real challenges for effective management. In eastern Australia the study of estuari
