A repeatable divorce pattern was found in this population of wandering albatrosses. Females were likely to spread their reproduction with several partners throughout their life as a bet-hedging strategy, while males were probably forced to divorce. In wandering albatrosses, divorce did not seem to be an adaptive process because there was no improvement of breeding success following divorce even when the effects of the first breeding attempt made by a newly formed pair was excluded, and poor reproductive performance had no impact on divorce probability. The distinct mechanisms of pair-bond disruption between sexes lead to a reduction of remaining lifetime reproductive success only in male individuals because of the difficulty of finding a new female partner in this male-biased population with consequently several missed reproductions.</span></p>

Since 2014, it has spread along the entire Florida Reef Tract and into the greater Caribbean, where it affects over one-third of Caribbean reef-building coral species, presumably via a water-borne vector. In January 2019, it was first detected in St. Thomas, United States Virgin Islands (USVI). To more quickly identify and respond to this coral disease outbreak, we developed a rapid pipeline for microbiome characterization, which employed the portable, high-accuracy sequencing platform, the Illumina iSeq 100 System. By transforming a home rental in St. Thomas, USVI, to a molecular laboratory, we collected, processed, and sequenced diseased or apparently healthy coral tissues and near-coral seawater from four coral species over a span of 10 days. Analysis of microbial communities associated with diseased tissue revealed 25 SCTLD-enriched amplicon sequence variants (ASVs). Furthermore, these taxa were detectable in near-coral seawater, a potential recruitment zone for pathogens. Disease-associated ASVs belonging to </span><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:italic;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Vibrio</span><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">, </span><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:italic;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Arcobacter</span><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">, Rhizobiaceae, and Rhodobacteraceae revealed representatives of previously identified coral disease-associated bacteria as well as undescribed lineages not previously associated with corals. This work represents the first rapid coral disease sequencing effort and offers specific bacterial targets for SCTLD research, which could help slow or stop the spread of this unprecedented coral disease.</span></b></p>
