Physical Functionality

Abstract Diseases are major drivers of the deterioration of coral reefs, linked to major declines in coral abundance, reef functionality, and reef-related ecosystems services1-3. An outbreak of a new disease is currently rampaging through the populations of the remaining reef-building corals across the Caribbean region. The outbreak was first reported in Florida in 2014 and reached the northern Mesoamerican reef by summer 2018, where it spread across the ~ 450-km reef system only in a few months4. Rapid infection was generalized across all sites and mortality rates ranged from 94% to < 10% among the 21 afflicted coral species. This single event further modified the coral communities across the region by increasing the relative dominance of weedy corals and reducing reef functionality, both in terms of functional diversity and calcium carbonate production. This emergent disease is likely to become the most lethal disturbance ever recorded in the Caribbean, and it will likely result in the onset of a new functional regime where key reef-building and complex branching acroporids (a genus apparently unaffected) will once again become conspicuous structural features in reef systems with yet even lower levels of physical functionality.

Anastasia, a student at the University of Toronto, St. George, is pursuing a Bachelor of Science Double Major in Physics and Caribbean Studies and a Minor in Mathematics. She is a pianist, plays the guitar and steelpan and spends her free time arranging music. Her love for soca music and steelpan in no way takes away from her passion for classical piano and physics. As a person of the Trinidadian Diaspora with many interests, Ana has decided to look at the Caribbean from a different perspective by combining her love for science and the region.

Sexual Pattern

The sexual pattern, reproductive mode, and timing of reproduction ofIsophyllia sinuosaandIsophyllia rigida, two Caribbean Mussids, were assessed by histological analysis of specimens collected monthly during 2000–2001. Both species are simultaneous hermaphroditic brooders characterized by a single annual gametogenetic cycle. Spermatocytes and oocytes of different stages were found to develop within the same mesentery indicating sequential maturation for extended planulation. Oogenesis took place during May through April inI. sinuosaand from August through June inI. rigida. Oocytes began development 7–8 months prior to spermaries but both sexes matured simultaneously. Zooxanthellate planulae were observed inI. sinuosaduring April and inI. rigidafrom June through September. Higher polyp and mesenterial fecundity were found inI. rigidacompared toI. sinuosa. Larger oocyte sizes were found inI. sinuosathan inI. rigida, however larger planula sizes were found inI. rigida. Hermaphroditism is the exclusive sexual pattern within the Mussidae while brooding has been documented within the related generaMussa,ScolymiaandMycetophyllia. This study represents the first description of the sexual characteristics ofI. rigidaand provides an updated description ofI. sinuosa.

The Caribbean

Since Fidel Castro came to power nearly a quarter-century ago, diplomats from Latin America, politicians from North America, and academics from both hemispheres have been asking how to involve Cuba in the Caribbean peacemaking process. More often than may be warranted by evidence, they have assumed that Cuban interests are consonant with those of the other states of the Caribbean region. Any objection to the word interests as being too strong is met by a barrage of rhetorical arguments purporting to demonstrate that, at the very least, a modus vivendi is possible. But Cuban communism is a sore thumb and not easily disposed of by appeals to use the opposite hand.

Proxy Data

The field of demography addresses the composition of human populations, their size, structure and development. The sources with which to conduct demographic analysis in archaeology can incorporate proxy data from areas of settlements, historical or ethnographic sources such as census data or parish burial registers, radiocarbon date densities, or human skeletal remains. The present study aims to use data from human skeletal remains to address questions relating to the size of the population of Roman York.
