Abstract The potential of corals to associate with more temperature‐tolerant strains algae (zooxanthellae, Symbiodinium ) can have important implications for the future coral reefs in an era global climate change. In this study, genetic identity and diversity zooxanthellae was investigated at three contrasting histories bleaching mortality, water temperature shading, Republic Palau (Micronesia).

Abstract: Species that periodically and predictably congregate on land or in the sea can be extremely vulnerable to overexploitation. Many coral reef fishes form spawning aggregations are increasingly target of fishing. Although serious declines well known for a few species, extent this behavior among impacts aggregation fishing not appreciated widely. To profile aggregating species globally, establish baseline future work, strengthen case protection, we (as members Society Conservation Reef...
The duration of the planktonic larval stage Indo-West Pacific damselfishes (Pomacentridae) is inferred from microstructure their otoliths and related to development morphologically distinct, localized populations interspecific differences in geographic distribution. Mean varies between species 0-37.4 d, differing significantly among species, genera subfamilies. Both morphological genetic data suggest sub-populations are most common with durations less than approximately 15 d. breadth a...
Hermaphroditic sexual patterns are widespread among teleosts and especially characteristic of certain perciform families. Among the most diverse groups hermaphroditic species groupers, hamlets sea basses family Serranidae. Like other epinepheline serranid, Epinephelus striatus , Nassau grouper, has long been assumed to exhibit monandric protogyny (a form hermaphroditism in which all males derive from adult females by sex change). Histological demographic data, however, indicate that pattern...
Seagrass ecosystems provide critical contributions (goods and perceived benefits or detriments) for the livelihoods wellbeing of Pacific Islander peoples. Through in-depth examination provided by seagrass across Island Countries Territories (PICTs), we find a greater quantity in Near Oceania (New Guinea, Bismarck Archipelago Solomon Islands) western Micronesian (Palau Northern Marianas) regions; indicating stronger coupling between human society ecosystems. We also many non-material...

Antibacterial-guided fractionation of an extract a deep-water Topsentia sp. marine sponge led to the isolation two new indole alkaloids, tulongicin A (1) and dihydrospongotine C (2), along with known analogues, spongotine (3) dibromodeoxytopsentin (4). Their planar structures were determined by NMR spectroscopy. absolute configurations through combination experimental computational analyses. Tulongicin is first natural product contain di(6-Br-1H-indol-3-yl)methyl group linked imidazole core....
Abstract Tropical Pacific seawater and precipitation stable oxygen isotope data aid in understanding modern oceanic atmospheric interactions, these are particularly valuable as they archived isotope‐based paleoclimate records. However, the absence of time series limits ability to identify influences on data, precluding robust interpretations. We present a new 10 year sub‐monthly record values (δ 18 O sw δ p ) from Koror, Palau. Our dataset indicates that temporally, is strongly influenced by...
A new sulfated cyclic depsipeptide, termed mutremdamide A, and six highly N-methylated peptides, koshikamides C−H, were isolated from different deep-water specimens of Theonella swinhoei cupola. Their structures determined using extensive 2D NMR, ESI, or CDESI QTOF-MS/MS experiments absolute configurations established by quantum mechanical calculations, advanced Marfey's method, chiral HPLC. Mutremdamide displays a rare 2-amino-3-(2-hydroxyphenyl)propanoic acid Nδ-carbamoyl-β-sulfated...
Seagrass ecosystems exist throughout Pacific Island Countries and Territories (PICTs). Despite this area covering nearly 8% of the global ocean, information on seagrass distribution, biogeography, status remains largely absent from scientific literature. We confirm 16 species occur across 17 22 PICTs with highest number in Melanesia, followed by Micronesia Polynesia respectively. The greatest diversity occurs Papua New Guinea (13 species), attenuates eastward to two French Polynesia....
Four β-carbolines, plakortamines A−D, two cyclic peroxides, epiplakinic acids G and H, related γ-lactones, (2S*,4R*)- (2R*,4R*)-2,4-dimethyl-4-hydroxy-16-phenylhexadecanoic acid 1,4-lactones, were isolated from the deep-water sponge Plakortis nigra Palau. The structures of eight new metabolites elucidated by interpretation spectroscopic data. Most inhibited HCT-116 human colon tumor cell line.
The humphead wrasse Cheilinus undulatus formed resident spawning aggregations daily after high tide at specific locations along the seaward edge of Palau barrier reef. location and extent one aggregation site remained consistent for 6 years with no physical features distinguishing it from adjacent areas. Spawning was documented most months probably occurred year round possible seasonal lunar variation. males arrived first site, followed by females potentially small primary males. female to...
Abstract Thermally driven bleaching events are a growing concern for reef ecosystems across the tropics. To assess and predict thermal stress impacts on reefs, remotely observed sea surface temperature (SST) commonly is used; however, communities typically extend to depths where SST alone may not be an accurate measure of in situ variability. Here nearly two decades observations (2‐ 90‐m depth) at three stations around Palau used develop empirical model variability versus depth based level...
