Coral Bleaching: A Global Analysis of Bright Spots
Sully, Shannon Elizabeth (2020-12)Thermal-stress events associated with climate change cause coral bleaching and mortality that threatens coral reefs globally. Yet coral bleaching and coral cover patterns vary spatially and temporally, and few studies have ... -
Coral immunology and resistance to disease
Reed, Keven C.; Muller, Erinn M.; van Woesik, Robert (2010-06-11)Scleractinian corals (phylum Cnidaria, class Anthozoa) have innate immunological responses against infections. Research has recently suggested that corals also possess an adaptive-like immunological repertoire that recognizes ... -
Diversity partitioning of stony corals across multiple spatial scales around Zanzibar Island, Tanzania
van Woesik, Robert; Zvuloni, Assaf; Loya, Y. (2010-03-29)The coral reefs of Zanzibar Island (Unguja, Tanzania) encompass a considerable proportion of the global coralreef diversity and are representative of the western Indian Ocean region. Unfortunately, these reefs have been ... -
Does dark-spot syndrome experimentally transmit among caribbean corals?
Randall, Carly J.; Jordán-Garza, Adán Guillermo; Muller, Erinn M.; van Woesik, Robert (2016-01-20)Over the last half-century, coral diseases have contributed to the rapid decline of coral populations throughout the Caribbean region. Some coral diseases appear to be potentially infectious, yet little is known about their ... -
THE EFFECT OF ANTHROPOGENIC ACTIVITY ON SEA TURTLE NESTING AND HABITAT USAGE IN FLORIDA, USA
Linz, Raschelli Anna-Elizabeth (2018-05)Sea turtles have complex life histories that make them difficult to study. Using easily-accessible data, such as nesting and stranding occurrences, can help to efficiently elucidate driving factors in the population ... -
The Effects of Elevated pCO₂ and Temperature on the Embryonic Development, Larval Survivorship, Condition, Calcification, Morphology, and Behavior of the Florida Stone Crab, Menippe Mercenaria
Gravinese, Philip Michael (2016-11)The emission of greenhouse gases into the atmosphere over the last century has increased atmospheric and oceanic temperatures, and has led to a decrease in oceanic pH. The increased ocean temperatures and reduced pH have ... -
Effects of ocean acidification on the dissolution rates of reef-coral skeletons
van Woesik, Robert; van Woesik, Kelly; van Woesik, Liana; van Woesik, Sandra (2013-11-21)Ocean acidification threatens the foundation of tropical coral reefs. This study investigated three aspects of ocean acidification: (i) the rates at which perforate and imperforate coral-colony skeletons passively dissolve ... -
Effects of thermal stress on key processes driving coral-population dynamics
Roth, Lynnette; van Woesik, Robert; Köksal, Semen (2010-07-29)A primary goal of ecology is to understand population dynamics by quantifying key processes that regulate population densities through time. Change to any one process may alter the population trajectory, its genetic ... -
Genetic susceptibility, Colony size, and water temperature drive white-pox disease on the coral Acropora palmata
Muller, Erinn M.; van Woesik, Robert (2014-11-05)Outbreaks of coral diseases are one of the greatest threats to reef corals in the Caribbean, yet the mechanisms that lead to coral diseases are still largely unknown. Here we examined the spatial-temporal dynamics of ... -
Keep up or drown: adjustment of western Pacific coral reefs to sea-level rise in the 21st century
van Woesik, Robert; Golbuu, Yimnang; Roff, George (2015-07-22)Since the Mid-Holocene, some 5000 years ago, coral reefs in the Pacific Ocean have been vertically constrained by sea level. Contemporary sea-level rise is releasing these constraints, providing accommodation space for ... -
The Micronesia Challenge: Assessing the relative contribution of stressors on coral reefs to facilitate science-to-management feedback
Houk, Peter C.; Camacho, Rodney; Johnson, Steven; McLean, Matthew; Maxin, Selino; Anson, Jorg; Joseph, Eugene; Nedlic, Osamu; Luckymis, Marston; van Woesik, Robert (2015-06-18)Fishing and pollution are chronic stressors that can prolong recovery of coral reefs and contribute to ecosystem decline. While this premise is generally accepted, management interventions are complicated because the ... -
MODELING REEF-CORAL RESPONSE TO CLIMATE CHANGE
CACCIAPAGLIA, CHRISTOPHER WILLIAM (2016-12)Coral reefs are one of the most diverse ecosystems on the planet. They provide goods and services to millions of people living in the coastal tropics. Recently, however, rising sea-surface temperatures have been threatening ... -
MODELING THE NICHE SPACE OF CORAL ASSEMBLAGES ALONG THE FLORIDA REEF TRACT
McCaffrey, Kelly Renee (2017-10)Quantifying the niche space of organisms is critical for conservation and restoration purposes. Yet, with warming oceans, we cannot assume that the localities that were optimal for species in the past remain so today or ... -
Persistence and change in community composition of reef corals through present, past, and future climates
van Woesik, Robert; Edmunds, Peter J.; Adjeroud, Mehdi; Baskett, Marissa L.; Baums, Iliana B.; Budd, Ann F.; Carpenter, Robert C. C.; Fabina, Nicholas S.; Fan, Tungyung; Franklin, Erik C. (2014-10-01)The reduction in coral cover on many contemporary tropical reefs suggests a different set of coral community assemblages will dominate future reefs. To evaluate the capacity of reef corals to persist over various time ... -
Phenotypic variance predicts symbiont population densities in corals: A modeling approach
van Woesik, Robert; Shiroma, Kazuyo; Köksal, Semen (2010-02-12)We test whether the phenotypic variance of symbionts (Symbiodinium) in corals is closely related with the capacity of corals to acclimatize to increasing seawater temperatures. Moreover, we assess whether more specialist ... -
Predicting Coral Recruitment in Palau's Complex Reef Archipelago
Golbuu, Yimnang; Wolanski, Eric C.; Idechong, Jacques Wasai; Victor, Steven; Isechal, Adelle Lukes; Oldiais, Noelle Wenty; Idip, David; Richmond, Robert H.; van Woesik, Robert (2012-11-28)Reproduction and recruitment are key processes that replenish marine populations. Here we use the Palau archipelago, in the western Pacific Ocean, as a case study to examine scales of connectivity and to determine whether ... -
Prioritizing Key Resilience Indicators to Support Coral Reef Management in a Changing Climate
McClanahan, Tim R.; Donner, Simon D.; Maynard, Jeffrey Allen; MacNeil, M. Aaron; Graham, Nicholas Anthony James; Maina, Joseph M.; Baker, Andrew C.; Alemu I., Jahson Berhane; Beger, Maria; van Woesik, Robert (2012-08-29)Managing coral reefs for resilience to climate change is a popular concept but has been difficult to implement because the empirical scientific evidence has either not been evaluated or is sometimes unsupportive of theory, ... -
Relationships between the history of thermal stress and the relative risk of diseases of Caribbean corals
Randall, Carly J.; Jordán-Garza, Adán Guillermo; Muller, Erinn M.; van Woesik, Robert (2014)The putative increase in coral diseases in the Caribbean has led to extensive declines in coral populations. Coral diseases are a consequence of the complex interactions among the coral hosts, the pathogens, and the ... -

Repeated Thermal Stress, Shading, and Directional Selection in the Florida Reef Tract
van Woesik, Robert; McCaffrey, Kelly Renee (2017-06-08)Over the last three decades reef corals have been subjected to an unprecedented frequency and intensity of thermal-stress events, which have led to extensive coral bleaching, disease, and mortality. Over the next century, ...
