Scenario planning with linked land-sea models inform where forest conservation actions will promote coral reef resilience.

We developed a linked land-sea modeling framework based on remote sensing and empirical data, which couples sediment export and coral reef models at fine spatial resolution. This spatially-explicit (60 × 60 m) framework simultaneously tracks changes in multiple benthic and fish indicators as a function of land-use and climate change scenarios. We applied this framework in Kubulau District, Fiji, to investigate the effects of logging, agriculture expansion, and restoration on coral reef resilience. Under the deforestation scenario, models projected a 4.5-fold sediment increase (>7,000 t. yr-1) coupled with a significant decrease in benthic habitat quality across 1,940 ha and a reef fish biomass loss of 60.6 t. Under the restoration scenario, models projected a small (<30 t. yr-1) decrease in exported sediments, resulting in a significant increase in benthic habitat quality across 577 ha and a fish biomass gain of 5.7 t. The decrease in benthic habitat quality and loss of fish biomass were greater when combining climate change and deforestation scenarios. We evaluated where land-use change and bleaching scenarios would impact sediment runoff and downstream coral reefs to identify priority areas on land, where conservation or restoration could promote coral reef resilience in the face of climate change.

Plasma zinc, copper, and amino acid levels in the blood of autistic children.

Plasma zinc, copper, and amino acid levels have been measured in a group of autistic children. All three variables were found to be normal. These findings are in disagreement with the previously reported results of some other workers but if confirmed would indicate that autism cannot simply be attributed to a disorder of zinc metabolism.

The adult presenting idiopathic Fanconi syndrome.

The adult presenting Fanconi syndrome is a rare familial disorder. A 30-year follow-up of one of the original families in the literature is reported here. Two important points have emerged. Firstly, the inheritance in this family is dominant, not recessive as originally suggested, and there remains no good example in the literature of a recessive inheritance of this disorder. Second, in this family lactic aciduria and tubular proteinuria are probably the earliest manifestations of the disorder in childhood, with glycosuria and aminoaciduria developing in the second decade and osteomalacia from the start of the fourth decade. Glomerular function deteriorates slowly but is compatible with a normal lifespan.
