PHENOLOGY OF SCRAMBLE POLYGYNY IN A WILD POPULATION OF CHRYSOMELID BEETLES: THE OPPORTUNITY FOR AND THE STRENGTH OF SEXUAL SELECTION [CORRECTED].

Phenology of scramble polygyny in a wild population of chrysomelid beetles: the opportunity for and the strength of sexual selection [corrected].

Recent debate has highlighted the importance of estimating both the strength of sexual selection on phenotypic traits, and the opportunity for sexual selection.We describe seasonal fluctuations in mating dynamics of Leptinotarsa undecimlineata (Coleoptera: Chrysomelidae).We compared several estimates of the opportunity for, and the strength of, sex

Modelling of the Production of Source Neutrons from Low-Voltage Accelerated Deuterons on Titanium-Tritium Targets

Fast quasi-monoenergetic neutrons can be produced by accelerating charged deuterons on tritium solid targets.Benchmark experiments were performed in many laboratories with intense D-T neutron sources.The aim is to validate the computational models and nuclear data for fusion applications.The detailed information on the neutron source term is highly

Arsenic in Groundwater: A Review of Current Knowledge and Relation to the CALFED Solution Area with Recommendations for Needed Research

Ground water with arsenic concentrations greater than the U.S.Environmental Protection Agency drinking water standard exists throughout much of the CALFED solution area.These high concentrations are of con-cern from the standpoint of both existing water supply and development of conjunctive use projects.Much is known about arsenic mobility in groun
