Crustose coralline algae biomineral-bound nitrogen isotopes provide a baseline to reconstruct coral trophic strategies

Jonathan Jung, Tanja Wald, Alan Foreman, Aaron L. Bieler et autres

Abstract Coral resilience is shaped by trophodynamic flexibility – the balance between photosymbiont-derived energy and feeding-based heterotrophy – yet quantifying this balance across taxa and through time remains difficult. Nitrogen (N) isotopes are a powerful tool to investigate trophic strategies, but their …

Terrigenous inputs link nutrient dynamics to microbial communities in a tropical lagoon

Christian John, Nyssa J. Silbiger, Thomas C. Adam, Danielle M. Barnas et autres

Abstract Nutrient availability drives community structure and ecosystem processes, especially in tropical lagoons that are typically oligotrophic but often receive allochthonous inputs from land. Terrestrially derived nutrients are introduced to tropical lagoons by surface runoff and submarine groundwater discharge, which are influenced …

Survivorship and growth of corals in Hawai‘i two years post-bleaching: signs of resilience

Courtney S. Couch, Thomas A. Oliver, Orion S. McCarthy, Kelly E. Speare et autres

The persistence of coral reefs is contingent on the capacity of corals to survive heat stress events, which are driving the worldwide increase in the frequency and severity of coral bleaching events. We used large-area imagery to track the post-bleaching fate of …

Utility of indicator thresholds across spatial gradients for applications to ecosystem‐based fisheries management

Shannon M. Hennessey, Jamison M. Gove, Mary K. Donovan

Abstract Ecosystem‐based fisheries management (EBFM) is increasingly recognized as an effective management strategy, especially in systems with dynamic components that have integrated responses to interacting drivers. Management targets therefore need to incorporate these complex dynamics, which may be accomplished by establishing targets …

Unifying Coral Reef States Through Space and Time Reveals a Changing Ecosystem

Simon J. Brandl, Jérémy Carlot, Rick D. Stuart‐Smith, Sally A. Keith et autres

ABSTRACT Aim Ecological state shifts that alter the structure and function of entire ecosystems are a concerning consequence of human impact. Yet, when, where and why discrete ecological states emerge remains difficult to predict and monitor, especially in high‐diversity systems. We sought …

Ethanol‐induced lung and cardiac right ventricular inflammation and remodeling underlie progression to pulmonary arterial hypertension

Mary K. Donovan, Abdel A. Abdel‐Rahman

BACKGROUND: Current research on ethanol-induced cardiovascular anomalies has focused on left ventricular (LV) function and blood pressure. To extend this area of research, we sought to determine whether ethanol-induced alterations in the structure and function of the right cardiac ventricle (RV) and …

Evidence for managing herbivores for reef resilience

Mary K. Donovan, Chelsie W. W. Counsell, Megan J. Donahue, Joey Lecky et autres

Herbivore management is an important tool for resilience-based approaches to coral reef conservation, and evidence-based science is needed to enact successful management. We synthesized data from multiple monitoring programs in Hawai'i to measure herbivore biomass and benthic condition over a 10-year period …

Complex drivers of invasive macroalgae boom and bust in Kāne'ohe Bay, Hawai'i

Morgan Winston, Kimberly Fuller, Brian J. Neilson, Mary K. Donovan

Invasive macroalgae Eucheuma sp. and Kappaphycus spp. (E/K) became a dominant benthic feature in Kāne'ohe Bay throughout the past four decades - occurring on up to 74 ha of reef area and growing up to three meters thick, which prompted intensive management …
