Coral reefs are the epitome of species diversity, yet number described scleractinian coral species, framework-builders reefs, remains moderate by comparison. DNA sequencing studies rapidly challenging this notion exposing a wealth undescribed but evolutionary and ecological significance diversity largely unclear. Here, we present an annotated genome for one most ubiquitous corals in Indo-Pacific (Pachyseris speciosa) uncover, through comprehensive genomic phenotypic assessment, that it...
Sea urchins (echinoids) were integrated into many aspects of prehistoric Oceanic society as they provided food, raw material for abrading tools and rare ornaments, used offerings on shrines (ko'a) in the Hawaiian Islands. We privilege seven habitation shrine assemblages (mostly dating to late prehistory; i.e., post AD 1500s) situated along a ∼12-km length rocky windward coast Moloka'i, Islands, where some densest concentrations have been recorded from Oceania. examined >185,000 urchin...
The extensive Venezuelan coastline is very important for understanding the evolution of Caribbean marine fauna. We report new fossil material collected from three Neogene sites in Falcon Basin and present first diversity analysis known echinoids Venezuela other regions. Five species are reported time Venezuela. Each shows a different taxonomic composition, which may be consequence differing palaeoecological conditions during Neogene. Furthermore, environmental changes caused by closure...
Clypeaster is a speciose echinoid genus with almost 50 extant and approximately 350 extinct species, encompassing great heterogeneity of form. While some attempts to subdivide this have been made, none has gained widespread support, all recent taxonomic treatments left the intact. Here we report new data on internal buttress arrangement, determined from X-Ray tomography, plate architecture, use establish relationships amongst 19 species 8 10 nominal subgenera that proposed. A cladistic...
Abstract Biodiversity hotspots are increasingly recognized as areas of high taxonomic and functional diversity. These dynamic shift geographically over time in response to environmental change. To identify drivers the origin, evolution, persistence diversity hotspots, we investigated patterns reef-building corals (Scleractinia) Central Indo-Pacific, a marine biodiversity hotspot for last 25 Myr. We used scleractinian fossil record (based on literature newly acquired collection) examine from...
Subtropical reefs are important habitats for many marine species and tourism recreation. Yet, subtropical understudied, detailed habitat maps seldom available. Citizen science can help fill this gap, while fostering community engagement education. In study, 44 trained volunteers conducted an ecological assessment of Flinders Reef using established Check CoralWatch protocols. 2017, 10 sites were monitored to provide comprehensive information on reef communities estimate potential local...

Abstract A robust marine radiocarbon ( 14 C) reservoir correction (ΔR) is essential for calibrating C dates of mollusks and fish bones routinely found in archaeological sites as discarded food remains terrestrial animals (including humans) with an appreciable diet. New ΔR values are reported the atoll archipelago Marshall Islands, eastern Micronesia. Atolls consist biogenetic material—mostly coral foraminifera—that can be directly dated establishing sequences emergence islet development....
A new fossil coral collection enhances our understanding of scleractinian diversity during the origination Indo-Pacific biodiversity hotspot (Oligocene -earliest Miocene).The corals were collected from Sarawak (Malaysia), Negros and Cebu (the Philippines).The oldest specimens are Cebu, found in Calagasan Formation (late Oligocene -middle Chattian) Butong Limestone -late Chattian).The Trankalan/Binaguiohan (Negros), Melinau Subis (Sarawak) all early Miocene (Aquitanian) age.Forty-four...
ABSTRACT The infaunal living clypeasteroid echinoid genus Echinocyamus is considered a model organism for various ecological and paleontological studies since its distribution ranges from the polar regions to tropics, shallow-marine settings deep-sea. Deep-sea analyses of this are rare, but imperative understanding function these important ecosystems. During 2012 Southern Surveyor expedition, 35 seamounts off east coast Australia were dredged in depths greater than 800 m. Of these, six...
Strontium isotope stratigraphy (SIS) is a valuable dating tool used to date and correlate marine sediments by comparing the ratio of Sr isotopes in carbonates composite reference curve. However, original 87Sr/86Sr ratios carbonate rocks are easily altered contamination with that bears different isotopic signature sourced from direct terrigenous or diagenetic fluids. This alteration renders useless for correlation purposes. Traditionally petrographic techniques major element analysis have...
Abstract Subtropical reefs are unique ecosystems that require effective management – informed by regular ecological monitoring to foster resilience environmental changes. Resources conduct limited, and citizen science can complement data from local agencies. Here, efforts document the status of a subtropical reef, Flinders Reef, Moreton Bay Marine Park, Australia. Ecological surveys, following Reef Check Australia CoralWatch protocols, were conducted 44 trained volunteers. Ten sites at...
Games as a didactic tool (e. g., puzzles) are gaining recognition in environmental education to promote skill development, but also develop specific understanding of the natural world. However, children’s puzzle containing representations nature may unwillingly lead “misconceptions” biodiversity themes and processes, an over-simplification relationship between people nature. To solve this problem, positive connotations prompt conceptual change more nuanced, multifaceted conception biodiversity.
