What does "SCTLD" mean?
Table of Contents
Stony Coral Tissue Loss Disease, or SCTLD, is a serious illness affecting coral reefs, particularly in the Caribbean. This disease leads to the death of corals, causing significant harm to reef ecosystems.
How SCTLD Affects Corals
SCTLD spreads quickly and causes visible tissue loss in corals. The affected corals may appear pale or bleached, and over time, they can die. This not only impacts the corals themselves but also the marine life that depends on healthy reefs for habitat and food.
Changes in Microbes
The presence of SCTLD alters the tiny organisms, or microbes, living on and within corals. These microbes play a role in the health of the corals. Studies show that when SCTLD is present, the types and amounts of microbes can change. Some species of corals are more affected than others, showing greater differences in their microbiomes when sick.
Importance of Healthy Corals
Coral reefs are vital for ocean health and provide many benefits, including supporting different fish species, protecting shorelines, and contributing to tourism. Understanding SCTLD and its effects is crucial for protecting these important ecosystems and finding ways to help the corals recover.
