The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL access_formats String .htmlTable,.csv,.json,.mat,.nc,.tsv
attribute NC_GLOBAL acquisition_description String Surveys were conducted using snorkel on the reef crest and the reef table, in
shallow sites at depths between 1.5 and 3 meters.

Fish community characterization

All fish were identified to the species level and counted along 50 m
transects, in the same habitat and area as the quadrats, parallel to the reef
crest and in 1.5-5 m in depth. The transect count area extended from the sea
floor to the surface of the water column and consisted of at least two 50 m
long swaths surveyed sequentially at each site. For all transects in all
years, the same diver Hirst counted mobile fish on a 5 m wide swath, before
returning along the same transect and counting cryptic benthic fishes on a 1 m
wide swath. The total lengths of all fishes were estimated to the nearest cm.
For analysis of fish community structure, fish species were
classified\u00a0into one of Hive trophic guilds: 1. herbivores, 2.
planktivores, 3. corallivores, 4. carnivores, and 5. piscivores. Species that
have a wider trophic range (omnivores) were categorized by their main food
preference according to the 5 categories mentioned above. Biomass was
estimated using the published length/weight relationships most appropriate for
the region (Adam et al., 2011; Froese & Pauly, 2000; Kulbicki et al., 2005).
Sharks and large rays were occasionally seen on transects, but their overall
low abundance makes band transects a poor approach to estimate their actual
numbers and contribution to biomass. Therefore elasmobranchs were recorded,
but not included in our calculations here.

attribute NC_GLOBAL project String The impact of a large episodic disturbance on an invasive (outbreak) coral: Will Typhoon Maysak promote or suppress an invasive Montipora sp. Coral on reefs of Ulithi Atoll, Federated States of Micronesia?
attribute NC_GLOBAL projects_0_acronym String DisturbImpactsCoral
attribute NC_GLOBAL projects_0_description String Extracted from the NSF award abstract:
Ulithi Atoll, in the Federated States of Micronesia, is the fourth largest Atoll in the world, and was an important staging area for the US Navy 3rd fleet during WWII. The Atoll contains dynamic coral reefs, and communities of people that depend on them. Ulithi has been subjected to a number of human and natural disturbances, including Typhoon Ophelia that hit in 1960. Local fishermen believe that this event started an invasion process by a 'weedy' invasive coral that covers reefs, and removes essential habitat for fish and octopus, potentially threatening these ecosystems. Four years ago, local people invited the investigators to Ulithi to study the reefs and work together to enhance fisheries and reef health. The investigators sequenced the invading coral DNA and identified it as a new species of Montipora. However, its invasion dynamics remain a mystery. In early April 2015, Ulithi was hit again by a major disturbance: super Typhoon Maysak. The Typhoon destroyed most structures on the island, and removed much of the coral formations visible from shore. Using their baseline data of the past four years, the investigators, along with a team of students, seek to map the effect of the Typhoon on the invasive Montipora. Using genomic sequencing, they hope to better understand the role of Typhoon Maysak on the establishment and dispersal of this invasive coral. This project provides a unique opportunity to study the effects of a rare event, and invasion processes, and to broadly disseminate findings, raising awareness about coral reefs, climate change, and unique human-natural coupled systems.�
Super typhoon Maysak struck Ulithi Atoll on March 31, 2015, where an invasive/outbreak species of Montipora has affected shallow coral reefs over at least the last 50 years. The research the investigators propose will elucidate the effects of this rare but high impact event on a biological invasion using genomics and reef sampling to investigate Micronesian reefs that were dominated by Montipora before the typhoon, and more 'pristine' reefs where Montipora was absent or in low densities. The investigators will be relating these findings to existing data that were collected from these sites over the past four years. These studies will advance our understanding of biological invasions in coral reef systems, explore the unusual occurrence of a coral species as an outbreak organism, and contribute to our knowledge of how high impact, episodic disturbances - likely to increase in frequency with the advance of global climate change - may affect threated coral reef ecosystems world-wide.
