Recruitment overfishing (the reduction of a spawning stock past a point at which the stock can no longer replenish itself) is a common problem which can lead to a rapid and irreversible fishery collapse. Averting this disaster requires maintaining a sufficient spawning population to buffer stochastic fluctuations in recruitment of heavily harvested stocks.(More)
Variation in local environmental conditions can have pronounced effects on the population structure and dynamics of marine organisms. Previous studies on crown-of-thorns starfish, Acanthaster planci, have primarily focused on effects of water quality and nutrient availability on larval growth and survival, while the role of maternal nutrition on(More)
One of our goals for the echinoderm tree of life project ( http://echinotol.org ) is to identify orthologs suitable for phylogenetic analysis from next-generation transcriptome data. The current dataset is the largest assembled for echinoderm phylogeny and transcriptomics. We used RNA-Seq to profile adult tissues from 42 echinoderm specimens from 24 orders(More)
Sexuality and reproductive mode are two fundamental life-history traits that exhibit largely unexplained macroevolutionary patterns among the major groups of multicellular organisms. For example, the cnidarian class Anthozoa (corals and anemones) is mainly comprised of gonochoric (separate sex) brooders or spawners, while one order, Scleractinia(More)
This list is strictly limited to publications in peer-reviewed journals co-authored by members of the lab and is presented in reverse chronologic order. Other contributions such as chapters in books, conference presentations, special publications, book reviews, etc., as well as the latest peer-reviewed articles can be found through our website : Shelter(More)
White syndrome (WS) is currently the most prevalent disease of scleractinian corals in the Indo-Pacific region, with an ability to exist in both epizootic and enzootic states. Here, we present results of an examination of WS lesion dynamics and show that potentially associated traits of host morphology (i.e., branching vs. massive), lesion size, and tissue(More)
Behavior, color, body size, spicules, and mitochondrial DNA were examined in two morphs from the Bohadschia marmorata (Jaeger, 1833) species complex in Micronesia to test whether they are conspecific. This complex consists of eight morphs that have been described as separate species and combined in various ways for over a century. We examined the classic B.(More)
