Within a population of simultaneous hermaphrodites, individuals may vary in both their current reproductive investment (biomass invested in gonads) and in how they allocate that investment between male and female function. In the chalk bass, Serranus tortugarum, estimates of both reproductive allocation and reproductive success as a male and a female can be(More)
The black hamlet (Hypoplectrus nigricans, Serranidae) is a simultaneous hermaphrodite, like many other serranines. It has external fertilization and planktonic eggs and engages in a kind of reciprocal spawning consisting of three components: (1) The clutch is divided into sequentially spawned parcels. (2) Partners regularly alternate release of parcels in a(More)
The evolutionary stability of simultaneous hermaphroditism depends in part on the existence of constraints on the potential for male mating success. In the seabasses (Serranidae), several species of simultaneous hermaphrodites divide each day's clutch of eggs into parcels that are spawned sequentially and alternately with a partner. This behavior is thought(More)
The lantern bass, Serranus baldwini, is a small hermaphroditic serranid found adjacent to coral reefs throughout the Caribbean. Data from gonad inspection, spawning behavior, and gamete release from individuals all confirm that populations consist of simultaneous hermaphrodites and males. This gender pattern appears to be sequential, with larger males(More)
The information and communications technology (ICT) industry has evolved greatly over the last half century. The technology is ubiquitous and increasingly integral to almost every facet of modern society. ICT devices and components are generally interdependent, and disruption of one may affect many others. Over the past several years, experts and policy(More)
This panel brings together usability and voting experts to discuss voting user experience in American governmental elections. Technological improvements and voting debacles have made this a special time for improving voting user experience. Can technologists improve the confidence citizens have in the voting system? What are the roles of teaching materials,(More)
