Using state-level data from the United States, we find that initial legal systems in territories originally settled by Great Britain – a common law country – and in territories originally settled by France, Spain, and Mexico and the Netherlands all civil law countries have persistent effects on the quality of contemporary institutions. In order to explain these findings, we develop a transplant...

Spatial and temporal variability in distribution and growth of newly settled red drum Sciaenops ocellatus were examined in the Aransas Estuary, Texas, USA. Overall, 1891 red drum larvae and early juveniles (4 to 30 mm standard length. SL) were identified from weekly epibenthic sled collections taken during the annual recruitment period (September-December 1994). Densities ranged from 0.0 to 3.4...

Varying densities of the spring generation of the hemlock woolly adelgid were manipulated on 16 previously uninfested eastern hemlocks in an open-field plantation in Massachusetts. In contrast to experimentally created hemlock woolly adelgid populations in a forest, as reported previously, there was no evidence of density-dependent survival on a tree-wide basis in the plantation in the spring (...
