title: Respiration rates and protein content of larvae from experiments investigating heat priming in Nematostella vectensis

description: Across diverse taxa, sublethal exposure to abiotic stressors early in life can lead to benefits such as increased stress tolerance upon repeat exposure. This phenomenon, known as hormetic priming, is largely unexplored in early life stages of marine invertebrates, which are increasingly threatened by anthropogenic climate change. To investigate this phenomenon, larvae of the sea anemone and model marine invertebrate Nematostella vectensis were exposed to control (18 °C) or elevated (24 °C, 30 °C, 35 °C, or 39 °C) temperatures for 1 hour at 3 days post-fertilization (DPF), followed by return to control temperatures (18 °C). The animals were then assessed for growth, development, metabolic rates, and heat tolerance at 4, 7, and 11 DPF. To investigate a possible molecular mechanism for the observed changes in heat tolerance, the expression of heat shock protein 70 (HSP70) was quantified at 11 DPF. The study's findings suggest heat priming may augment the climate resilience of marine invertebrate early life stages via the modulation of key developmental and physiological phenotypes, while also affirming the need to limit further anthropogenic ocean warming.

This dataset includes data pertaining to the respiration rates and protein content of larvae. See related datasets for other results from these experiments. These data and results are published in Glass et al. (2023) (DOI: 10.7717/peerj.16574).

title: Larvae in the planula stage 3 days post-fertilization following parental ocean acidification during lab experiments conducted in spring 2022.

description: Ocean acidification (OA) resulting from anthropogenic CO2 emissions is impairing the reproduction of marine organisms. While parental exposure to OA can protect offspring via carryover effects, this phenomenon is poorly understood in many marine invertebrate taxa. We examined how parental exposure to acidified (pH 7.40) versus ambient (pH 7.72) seawater influenced reproduction and offspring performance across six gametogenic cycles (13 weeks) in the estuarine sea anemone Nematostella vectensis. This dataset pertains to the performance of larvae following parental exposure to ocean acidification, specifically larval development.

title: Environmental temperature data collected at Cerro Mundo Bay, San Cristobal, Galapagos from 2022-2023 (Galapagos 2021 project)

description: Increased standing macroalgal biomass in upwelling zones is generally assumed to be the result of higher nutrient flux due to upwelled waters, However, other factors can strongly impact macroalgal communities. For example, herbivory and temperature, via their effects on primary producers and the metabolic demands of consumers, can also influence macroalgal biomass and productivity, respectively.  Although there is a fair number of studies looking at the interactive effects of herbivores and nutrients in both tropical and temperate regions, there is a lack of studies looking at these effects in tropical or subtropical upwelling regions. The purpose of this study was to measure the effects that herbivores, temperature, and nutrient availability have on standing macroalgal biomass. We manipulated nutrient availability and herbivory in six field experiments during contrasting productivity and thermal regimes (cool-upwelling and warm, non-upwelling season) on a subtidal nearshore rocky reef. 

Here, we present a set of temperature (°C) data collected at Cerro Mundo Bay, San Cristobal, Galapagos from September 2022 to February 2023. The environmental temperature was recorded every 15 minutes using a HOBO Water Temperature pro V2 Data Logger (Onset®) attached to the seafloor at a 10 meters depth mark.

title: Acropora cervicornis genomic/trancriptomic sequence accessions with associated data on tank exposure to white band disease and survival outcomes with corals collected from Florida, USA and Bocas del Toro, Panama in 2021

description: Genomic data was collected from 96 Acropora cervicornis samples, 48 of which were collected from the Coral restoration foundation nursery in Florida in June 2021 and the other 48 were collected from Bocas del Toro Panama in November 2021. All samples were sequenced using illumina short read sequencing to create whole genome sequencing profiles of the DNA with one of the Florida samples, the K2 genotype, being sequenced using additional Nanopore long reads to assemble and annotate an A. cervicornis genome. All genotypes were used in a disease exposure assay to assess individual genotype disease resistance with a further, 16 colonies from Florida being sequenced at two timepoints across disease exposed and healthy colonies (total 48 sequences) using RNAseq to identify patterns in differential gene expression based on disease resistance.

This dataset includes sample metadata, treatment information, and disease state for corals in the exposure experiment. Sample metadata and accession identifiers for sequences at The National Center for Biotechnology Information (NCBI) are included as a supplemental file.

title: Coral tissue mortality as a function of the presence or absence of sea cucumbers and coral outplant type in cage experiments in lagoonal habitat of Mo’orea, French Polynesia in April and May of 2020

description: Coral reefs are in global decline with coral diseases playing a significant role. Coral diseases are commonly sediment-associated and could be exacerbated by overharvest of sediment-feeding sea cucumbers. These data include visual assessments of coral (Acropora pulchra) tissue mortality among corals outplanted in 50 x 50 cm cages in sandy lagoonal areas of Mo’orea, French Polynesia (17.4894° S, 149.8825° W). Zero, one, or two Holothuria atra sea cucumbers were placed into each cage, as well as three treatments of the coral Acropora pulchra (n = 12 cages/treatment): (i) a coral branch with turf algae on the base separating live coral tissue from sediment by ~2.5 cm of turf (hereafter “turf”), ii) a coral with equivalent turf algae on its base but with the turf buried so that sediment contacted the coral’s live tissue at the turf-coral juncture (hereafter “buried turf”), or iii) a coral lacking turf on its base and its live tissue in direct contact with benthic sediment (hereafter “no turf”). Percent tissue mortality of each A. pulchra coral was monitored daily for 36 days (April-May 2020) or until tissue mortality of one more corals within a cage was estimated to be ≥50% of the coral’s branch height, after which all corals in that cage were collected for sampling and subsequent microbiome analyses. All coral tissue mortality data were collected by Dr. Cody Clements of the Georgia Institute of Technology.

title: Archived Oyster Samples Collected from the Delaware Bay from 2018 to 2021 (SEGO project)

description: The Selection along Estuarine Gradients in Oysters (SEGO) project is a collaborative NSF-funded effort to measure and understand the dynamics of short term adaptive change at small spatial scales. We focused on eastern oysters as an example of a common marine life history – high fecundity, complex life cycle with early larval dispersal, and sedentary (sessile for oysters) life after larval settlement. 

The data assembled in this data table are collections made over three years for two types of genomic analysis: (1) annual adult samples collected along the axis of the Delaware Bay estuary to capture a gradient in potentially stressful low salinities, (2) adult samples collected from mid-bay for experimental low-salinity challenge experiments, and (3) spat and broodstock collected for low salinity challenge experiments directly on wild spat or on larval progeny of broodstock collected from low vs. moderate salinity, respectively. Transect adults were collected by dredge in 2018, 2019 and 2021 from the same 5 subset of sites, each year, that the Rutgers Haskin lab consistently monitors every year to manage the oyster fishery. By piggy backing on the Haskin monitoring effort, the SEGO project has benefited from the long term data and deep understanding that Rutgers scientists have built about the Delaware Bay oyster population. 2021 was an exception because adults from an additional three sites were collected and analyzed. Two replicate challenge experiments on adults were accomplished in 2019 and 2020 using similar-size oysters collected from the highest oyster density part of the Delaware Bay population where environmental variation seems to generate the least mortality. Full details on the wild transect samples (genotype-environment association tests) and from the challenge experiment results comparing survivors vs. nonsurvivors are being prepared for publication. Spat collected in 2020 from across the salinity gradient were used for low salinity challenge experiments – results are published in Manuel et al. 2023. Broodstock collected in low vs. moderate salinity regions of the estuary in April 2021 were spawned to conduct a low salinity challenge experiment on their larvae, but larval performance and survival was too low for meaningful results.
