title: Cell counts exhibiting 'Selfish' uptake in the Western North Atlantic, in Danish coastal seawater, and abyssopelagic waters off the eastern coast of Japan under varying hydrostatic pressures, 2023-2024

description: Heterotrophic bacteria and archaea (here: microbes) are critical drivers of the ocean’s biogeochemical cycles, active throughout the depth of the ocean. Their capabilities and limitations help determine the rates and locations at which carbon and nutrients are regenerated, as well as the extent to which organic matter is preserved (Hedges 1992). In the deep ocean, at bathy- and abyssopelagic depths (ca. 1000-6000m), these communities are dependent upon the sinking flux of particulate organic matter (POM) from the surface ocean (Bergauer et al. 2018). This dependence means that heterotrophic microbial communities must produce the extracellular enzymes required to solubilize and hydrolyze high molecular weight (HMW) POM to sizes substrates suitable for cellular uptake. A recent global-scale investigation of deep-sea microbes in fact found that the genetic potential for exported (extracellular) enzymes among bacteria in deep waters was far greater than for communities in surface or mesopelagic waters (Zhao et al. 2020). We have new evidence that a substantial fraction of bacteria in bottom water from the North Atlantic Ocean use a specialized set of extracellular enzymes to rapidly take up HMW polysaccharides (Giljan et al. 2022), a substrate processing mechanism that would not be detected with the low molecular weight substrates used in most prior studies of microbial activity in the deep ocean (Nagata et al. 2010).
 
Through our collaboration with the Danish Center for Hadal Research, we were able to use pressurization systems and in situ specialized equipment to investigate the effects of pressures characteristic of bathy- and abyssopelagic depths on microbial communities and their extracellular enzymes in the open North Atlantic Ocean, in Danish Coastal Seawater, and abyssopelagic waters off the Eastern Coast of Japan. 
 
Here we present, in collaboration with colleagues from the Max Planck Institute for Marine Microbiology, the detection and quantification of microbial cells exhibiting selfish uptake behavior of fluorescently-labeled HMW polysaccharides. This dataset includes sample collection metadata, environmental variables, experimental variables, the number of cells detected exhibiting 'selfish' uptake, and total cellular abundance.

title: Survival of larval Strongylocentrotus purpuratus under ocean warming and food availability scenarios

description: We tested how thermal tolerance itself can be fundamentally altered by food limitation hypothesis by quantifying how temperature and food concentrations interact synergistically to shape survival throughout larval development of purple urchins (Strongylocentrotus purpuratus). Larval sampling was conducted every two days to estimate changes in larval density and competency, in conjunction with water changes and feedings. Larval densities were quantified by concentrating larval cultures to 100 mL and counting the number of larvae found in five 1 mL subsamples. Density counts continued until larvae showed signs of metamorphosis, as determined by the presence of a rudiment and exposed tube feet.

title: Larval morphometrics of Strongylocentrotus purpuratus under ocean warming and food availability scenarios

description: Trends in survival, morphometric patterns, and time to metamorphic competency across temperature and food availability treatments were measured in S. purpuratus larvae. 

Larvae were spawned from adult purple urchins collected in Santa Barbara, CA. Effects of temperature and food availability were tested using a 6 x 4 factorial experimental design with six temperature treatments (10, 12, 14, 16, 18, 20°C) and four concentrations of Rhodomonas sp. microalgae (500, 2500, 5000, 10,000 cells mL-1) for a total of 24 treatment combinations. Food treatments represented algal concentrations from starvation to ad libitum conditions. Temperature and food treatments were based on historical observations of temperature trends and chlorophyll abundance. Larval samples were collected 4, 9, and 15 days post-fertilization and fixed in 10% PBS buffered formalin for morphometric analyses. 

Samples were collected before feeding to minimize influence of algae on stomach measurements. Fixed larvae were then photographed using an Olympus BX41 compound microscope with a Nikon 3400 DSLR camera at 4X magnification and postoral arm length, body length, stomach length and height were measured in 20 randomly selected larvae from each sample using ImageJ, version 1.53t (Schneider et al. 2012). Metamorphic competency was determined when &gt;50% of larvae exhibited tube feet and adhered to the bottle.

title: Metadata for studies from meta-analysis investigating covariance between genetic and environmental (CovGE) effects in phenotypic results

description: Covariance can exist between the genetic and environmental influences on phenotype (CovGE) and can have an important role in ecological and evolutionary processes in nature and population responses to environmental change. CovGE is commonly called countergradient variation (CnGV; negative CovGE)or cogradient variation (CoGV; positive CovGE)and has been recognized in classic studies that have established several long-standing hypotheses about CnGV and CoGV. For instance, it is hypothesized that CnGV is more prevalent in nature than CoGV, that CnGV is more prevalent in fish, amphibian, and invertebrate taxa, across latitudinal or altitudinal environmental gradients, and more frequently occurs in metabolic compensation traits, including development, growth, feeding, metabolism, and activity, while CoGV is more commonly observed in morphological traits. The recent development of a standardized method to measure CovGE allows for the first rigorous quantitative exploration of these hypotheses. We use meta-analysis and apply the novel quantitative method to test whether the above hypotheses are supported in the literature. We found no differences in frequency of CnGV and CoGV, and no systematic patterns relative to taxa, environmental gradient, or trait type. However, our analyses suggest that CovGE may be as common as gene by environment (GxE) interactions. Given that CovGE is likely to have a strong impact on future outcomes for organisms experiencing environmental change, that significant CovGE occurred frequently, and the lack of systematic patterns in the occurrence of CovGE, we encourage a more widespread application of measuring CovGE.

title: Kelp Wet Weight Measurements before and after Deployment in Caged Pycnopodia Field Experiment in the Sitka Sound Urchin Barrens during February 2023 (High latitude kelp dynamics project)

description: While the recently decimated predatory sea star, Pycnopodia helianthoides, may support kelp forests by consuming herbivorous sea urchins, less is known about their non-consumptive effects. We conducted a field experiment in three replicate sea urchin barrens in Sitka Sound, Alaska in February of 2023, where we deployed pre-weighed Macrocystis pyrifera blades at discrete distances on four metre radial cables from caged adult P. helianthoides and control cages and reweighed after 24 hours. Our results suggest the chemical cue of P. helianthoides elicits a localised, species-specific landscape of fear that suppresses grazing, and that the non-consumptive effects of P. helianthoides on sea urchin behaviour may be important for kelp restoration.
