A thriving saltwater aquarium is a dynamic system—the populations of bacteria, algae, and invertebrate life adjust to the conditions you provide and resources available to them for growth. What does it take to have a successful, thriving saltwater... by Admin | Jan 7, 2019 | Invertebrates, Reef, Science
I came across a strange story in my inbox the other day. It chronicled a piece of research that examined how the relationship between a predator and a prey species was disturbed by leachates coming from micro... by Admin | Jan 4, 2019 | Corals, Reef, Science, Video
[embedded content] On November 27th we embarked on the first field trip with researchers from NOAA and University of Miami for the next phase of Coral Morphologic’s long-term project to document, study, and conserve Miami’s unusually resilient ‘urban corals’. That is, the corals that have pioneered into Miami’s intercoastal waterways as larvae and settled onto man-made infrastructure. It is precisely Miami’s legacy of anthropogenic disturbance that led Coral Morphologic to recognize that the City was a real-world window in which to understand how corals may adapt and evolve to anthropogenic impacts. Studying genetic variation and the underlying causes of these variations is at the heart of a global effort to identify more resilient coral genotypes capable of restoring degraded coral habitat. Most of this research has focused on traditionally healthy, offshore reef habitats and identifying corals that show more resilience to stress than neighbors, or in experimental lab settings with distinct coral colonies of the same species subjected to stressful conditions. However, our project proposes to sample the tissue of healthy coral colonies (specifically Pseudodiploria strigosa and Porites asteroides) living in less than ideal ‘urban’ conditions, as well as healthy coral living offshore in ‘natural’ conditions, to determine if the genetic variation between sites is significant. The sample sites will also be surveyed and scientifically described by community assessment and seasonal changes through photo mosaics, monitoring of water chemistry, temperature, pH, and light levels, to quantify and compare site conditions. The final phase of this project will involve transplanting corals to the tip of PortMiami from each of the ‘urban’ sites, along with fragments from the offshore, natural reef to compare how each is able to adapt, and eventually developing an ‘urban coral’ nursery to grow the most resilient coral genotypes for restoration of reefs and laboratory research. But the first task in this year-long study was to characterize each of the study sites through photo-mosaics that create three dimensional maps using a pair of GoPro cameras. These maps will serve as our detailed baseline imagery to better understand the forces of coral recruitment, growth, mortality, competition from macroalgae, and the accumulation of trash/ debris over time. Watch the video above to see each of the three urban coral research sites and the techniques used to document them. We look forward to providing updates over the course of the year as we document the sites, analyze transcriptomes, transplant corals, and characterize range of water quality and chemical conditions that Miami’s urban corals endure.

According to a news study from Georgia Tech that examined the microbe rich mucous layers of both clownfish and anemones, the two are swapping microbe flora, which may contribute to the fishes avoiding being... by Admin | Dec 24, 2018 | Science
I’ve just come across a press release about new research published in the journal Geophysical Research Letters, which suggests that rising sea levels may actually benefit low lying coral reef islands, which goes against the prevailing wisdom that island nations such... by Admin | Nov 30, 2018 | Conservation, Science
Marine biologists and climate scientists have started using the term ‘blue carbon’ to describe the amount of carbon that is locked up in marine ecosystems. One of the most effective ecosystems for removing carbon (in the form of CO2) from the atmosphere via the oceans...
