Specifically, the symbiont-bearing Globigerinoides ruber records higher B/Ca and d11B than Trilobatus sacculifer and Orbulina universa, and it has been hypothesized that these differences are caused by species-specific rates of symbiont photosynthesis and habitat depth. According to this hypothesis, greater symbiont photosynthesis elevates the microenvironmental pH of G. ruber to a greater degree than in T. sacculifer and O. universa. Here we test this hypothesis by applying fast repetition rate fluorometry (FRRF), Chlorophyll a quantification, and symbiont counts in laboratory grown specimens of G. ruber, T. sacculifer and O. universa to study species-specific differences in symbiont photosynthetic competency. In addition, we report B/Ca shell profiles measured by laser ablation on the same specimens previously monitored by FRRF, and d11B data of discrete populations of all three species grown under high and low light conditions in the laboratory. While the light experiments document that symbiont photosynthesis elevates pH and/or d11B in the calcifying microenvironment of all three foraminifer species, the FRRF, Chl. a and symbiont abundance data are relatively uniform among the three species and do not scale consistently with intra shell B/Ca, or with observed species-specific offsets in B/Ca or d11B. Implications of these findings for foraminiferal physiology and biomineralization processes are discussed. #--------------------------------------- # Funding_Agency # Funding_Agency_Name: National Science Foundation # Grant: OCE12-32987 #--------------------------------------- # Site_Information # Site_Name: Isla Magueyes, La Parguera and Santa Catalina Island # Location: Global Ocean # Northernmost_Latitude: 33.26 # Southernmost_Latitude: 17.92 # Easternmost_Longitude: -67 # Westernmost_Longitude: -118.29 # Elevation: #--------------------------------------- # Data_Collection # Collection_Name: ParagueraCatalina symbiont Hoenisch2020 # First_Year: 2013 # Last_Year: 2015 # Time_Unit: AD # Core_Length: # Notes: Laboratory Cultures #--------------------------------------- # Chronology_Information # Chronology: #--------------------------------------- # Variables # Data variables follow that are preceded by "##" in columns one and two. # Variables list, one per line, shortname-tab-longname components (9 components: what, material, error, units, seasonality, archive, detail, method, C or N for Character or Numeric data) ## foram_species notes,,,,,paleoceanography,,,C,foraminifer species ## culture_year collection date,,,,,paleoceanography,,,N, year of culture ## culture_loc sample identification,,,,,paleoceanography,,,C,culture location ## foram_id sample identification,,,,,paleoceanography,,,N,foram identification number ## largest_shell_dim length,foraminifer,,micrometer,,paleoceanography,,,N,largest shell dimension ## symb_quant1 symbiont,foraminifer,,count,,paleoceanography,,,N,symbionts/foraminifer; replicate measurement 1 of symbiont quantity ## symb_quant2 symbiont,foraminifer,,count,,paleoceanography,,,N,symbionts/foraminifer; replicate measurement 2 of symbiont quantity ## avg_symb_quant symbiont,foraminifer,,count,,paleoceanography,averaged,,N,symbionts/foraminifer; average of replicate measurements ## symb_quant_1sd symbiont,foraminifer,one standard deviation,count,,paleoceanography,,,N,symbionts/foraminifer; symbiont quantity uncertainty #------------------------ # Data: # Data lines follow (have no #) # Data line format - tab-delimited text, variable short name as header # Missing_Values: NA foram_species culture_year culture_loc foram_id largest_shell_dim symb_quant1 symb_quant2 avg_symb_quant symb_quant_1sd O. universa 2013 Santa Catalin Island 1795 395 613 529 571 60 O. universa 2013 Santa Catalin Island 727 407 485 520 503 25 O. universa 2013 Santa Catalin Island 774 412 520 763 641 172 O. universa 2013 Santa Catalin Island 443 437 675 624 649 36 O. universa 2013 Santa Catalin Island 1963 448 475 383 429 65 O. universa 2013 Santa Catalin Island 2005 472 261 368 314 76 O. universa 2013 Santa Catalin Island 966 475 1495 1679 1587 130 O. universa 2013 Santa Catalin Island 377 478 405 329 367 54 O. universa 2013 Santa Catalin Island 414 501 430 514 472 60 O. universa 2013 Santa Catalin Island 533 502 286 317 301 22 O. universa 2013 Santa Catalin Island 785 503 215 268 242 38 O. universa 2013 Santa Catalin Island 1692 510 920 667 794 179 O. universa 2013 Santa Catalin Island 1485 518 1694 2139 1917 314 O. universa 2013 Santa Catalin Island 387 545 1307 1383 1345 54 O. universa 2013 Santa Catalin Island 542 550 835 776 805 42 O. universa 2013 Santa Catalin Island 210 553 1012 1130 1071 83 O. universa 2013 Santa Catalin Island 410 591 1130 1526 1328 280 O. universa 2013 Santa Catalin Island 1215 600 1418 966 1192 320 O. universa 2013 Santa Catalin Island 1486 600 1418 1503 1461 60 O. universa 2013 Santa Catalin Island 389 607 1830 1619 1725 149 O. universa 2013 Santa Catalin Island 1317 613 1633 1280 1457 249 O. universa 2013 Santa Catalin Island 1085 626 1564 1242 1403 228 O. universa 2013 Santa Catalin Island 1278 684 2377 1365 1871 716 O. universa 2013 Santa Catalin Island 1315 803 1855 1434 1645 298 O. universa 2015 Puerto Rico NA 531 552 353 452 141 O. universa 2015 Puerto Rico NA 531 644 1173 909 374 O. universa 2015 Puerto Rico NA 568 682 552 617 92 T. sacculifer 2015 Puerto Rico NA 506 291 583 437 206 T. sacculifer 2015 Puerto Rico NA 462 575 291 433 201 T. sacculifer 2015 Puerto Rico NA 637 1579 1564 1572 11 G. ruber 2015 Puerto Rico NA 300 552 391 472 114 G. ruber 2015 Puerto Rico NA 331 422 399 410 16 G. ruber 2015 Puerto Rico NA 359 575 521 548 38 G. ruber 2015 Puerto Rico NA 424 759 376 567 271 G. ruber 2015 Puerto Rico NA 434 3044 2844 2944 141 G. ruber 2015 Puerto Rico NA 439 759 828 794 49 G. ruber 2015 Puerto Rico NA 458 874 437 656 309 G. ruber 2015 Puerto Rico NA 473 966 728 847 168 G. ruber 2015 Puerto Rico NA 473 230 452 341 157 G. ruber 2015 Puerto Rico NA 507 2438 2001 2220 309
