An increased understanding of the role of early life history stages in determining the distributions of benthic invertebrates require studies covering a wide range of habitats, and preferably multiple scales. For one of the more prominent invertebrate groups, intertidal barnacles, much of our existing knowledge is drawn from studies of rocky shores, with few studies from other habitats. Here, w...

In the late 1970's, when competition was introduced in the United States, competitive forces pushed international telephone prices down. Lower prices resulted, inter alia, in an increase in international calls (and minutes) from the U.S. to countries whose prices were high relative to U.S. prices. This increase in minute volume in turn resulted in a significant increase in settlement payments o...

We study the terms of credit in a competitive market in which sellers (lenders) are willing to repeatedly …nance the purchases of buyers (borrowers) by engaging in a credit relationship. The key frictions are: (i) the lender is unable to observe the borrower’s ability to repay a loan; (ii) the borrower cannot commit to any long-term contract; (iii) it is costly for the lender to contact a borro...

Water flow affects settlement of marine larvae on several scales. At the smallest scale local flow regime may control the probability of adhesion to the substrate. Our aim was to mechanistically understand the transition from suspended to attached larvae in turbulent flow. Recently it was proposed that opportunities for larval settlement in turbulent boundary layers depend on time windows with ...

Over small spatial scales, variation in the density of settlers of benthic sessile species is the result of interactions among larval behavior, local hydrodynamic conditions, and the physical, chemical and biological characteristics of the benthic habitat. It has been shown repeatedly that adult benthic filter-feeders can consume larvae of their own and other species, but their effects on the d...

Selective mortality during the early life stages in marine organisms can affect the magnitude and composition of recruitment, yet these processes have not been examined in economically important predatory coral reef fishes. Utilizing 3 different stage-specific sampling techniques (shipboard plankton tows, larval light traps, juvenile surveys/seines), we repeatedly sampled multiple cohorts of 3 ...

Studies of early post-settlement processes in coral reef fishes have focused on small, sedentary species and have neglected the larger, more mobile, fished species. However, because recently settled fishes of both types are small and sedentary, early post-settlement processes might be similar. Here, we compare early post-settlement population dynamics of two naturally co-occurring taxa, Spariso...

Elevated irradiance has a profound effect on the successful dispersal and establishment of kelp zoospores, affecting their physiology and viability. The research to date, however, has been on zoospores localized near the benthos, with little attention on the importance of vertical transportation and subsequent exposure to increased irradiance. Therefore, we wanted to investigate the effects of ...

THE 1959 Mental Health Act emphasises the need to integrate psychiatric patients with the community at large rather than to isolate them from it, as hitherto. This identification with the normal community has been the Ministry of Labour's approach to the employment of disabled people since the time of the Disabled Persons (Employment) <4ct of 1944. For the past 17 years all disabled people, whe...
