Myopia will affect half the global population by 2050 and is a leading cause of vision impairment. High-dose atropine slows myopia progression but with undesirable side-effects. Low-dose atropine is an alternative. We report the effects of 0.01% or 0.005% atropine eye drops on myopia progression in 13 Australian children aged between 2 and 18 years and observed for 2 years without and up to 5 years (mean 2.8 years) with treatment. Prior to treatment, myopia progression was either ‘slow’ (more positive than −0.5D/year; mean −0.19D/year) or ‘fast’ (more negative than −0.5D/year; mean −1.01D/year). Atropine reduced myopic progression rates (slow: −0.07D/year, fast: −0.25D/year, combined: before: −0.74, during: −0.18D/year, p = 0.03). Rebound occurred in 3/4 eyes that ceased atropine. Atropine halved axial growth in the ‘Slow’ group relative to an age-matched model of untreated myopes (0.098 vs. 0.196mm/year, p < 0.001) but was double that in emmetropes (0.051mm/year, p < 0.01). Atropine did not slow axial growth in ‘fast’ progressors compared to the age-matched untreated myope model (0.265 vs. 0.245mm/year, p = 0.754, Power = 0.8). Adverse effects (69% of patients) included dilated pupils (6/13) more common in children with blue eyes (5/7, p = 0.04). Low-dose atropine could not remove initial myopia offsets suggesting treatment should commence in at-risk children as young as possible.

Maturity Parameters

A sample of 100 Spiriferina stracheyi (Salter) from a single chronodeme of the Anisian Whitehorse formation, Alberta Rocky Mountains, is the subject of covariation studies (individual allomorphosis) in the parameters half width + length mean ("size"), half width/length ratio, thickness, apical angle of fold and sulcus boundaries (fold–sulcus angle), plicae frequency, and apical angle between second right and left plicae from the median (plicae angle). Changes of growth rates for half width/length and plicae frequency at a mean "size" of 10 mm suggest the attainment of maturity; parameters vary nearly independently from "size" in the sample of mature specimens. The variation in the parameters is unusually great. Significant correlation of −0.36 exists between half width/length and plicae angle, i.e. the plicae are more widely spaced in long ("rounded") valves than in wide ("alate") valve variants. A corresponding correlation of +0.61 exists for plicae frequency, wide valves averaging double as many plicae as narrow valves. The same correlations are present in a Himalayan sample of this species.Although, usually, shell plication of bivalved filter-feeders with accretionary growth may simply result from ecologic–physiologic functions of a plicate commissure, in the species here studied the plicae themselves might have had a mechanical function, i.e. the shell forming a corrugated membrane surface in which the "wavelength" increases with the axial growth of the membrane.

Axial Growth

We have taken a genetic approach to understanding the mechanisms that control vascular patterning in the leaves of higher plants. Here we present the identification and characterization of the lop1 mutant of Arabidopsis which is defective in basipetal transport of IAA. Mutant leaf midveins show disoriented axial growth, and bifurcation into twin veins that are frequently rotated out of the normal dorsal/ventral axis of the leaf. Mutant plants also display abnormal patterns of cell expansion in the midrib cortex and in the epidermis of the elongation zone of lateral roots. Lateral roots show abnormal curvature during initiation, sometimes encircling the primary root prior to growth in a normal downward direction. Mutant seedlings have normal levels of free IAA, and appear normal in auxin perception, suggesting that transport is the primary lesion. The abnormalities in vascular development, lateral root initiation and patterns of cell expansion observed in the lop] mutant are consistent with a basic disruption in basipetal transport of IAA.

Arene lychee sp. nov. is described from Canopus Bank, a seamount located ~190 km off Fortaleza, Ceará, NE Brazil (02°14’25”S, 38°22’50”W), based on shell morphology. The species is characterized by a large, trochiform shell; color ranging from intense reddish to white (darker on spiral cords, lighter at base) with a yellow apex; sculpture of 3‑8 wide spiral cords with large scale-like spines; cords separated by deep interspaces with similar width, and interspaces sculptured by closely-packed, thin axial growth lines.
