Of the approximately 50 workers known, one was collected in a Malaise trap sample and the rest were in Berlese or Winkler samples. The Winkler samples were of sifted litter and rotten wood on the forest floor; the Berlese samples were cores of forest floor litter and about 5–10 cm of the mineral soil beneath. At La Selva Biological Station, 3% of 208 Berlese samples and 2% of 640 miniWinkler samples contained workers. Given that each miniWinkler sample covered an area about 60 times greater than a Berlese sample (1 m 2 versus 165 cm 2), <i>R. subspatulata</i> was far more abundant in Berlese samples. This suggests that <i>R. subspatulata</i>, and perhaps <i>Rhopalothrix</i> in general, are subterranean, nesting and foraging in mineral soil, and perhaps only rarely venturing up into the litter layer. The pale color and greatly reduced eyes also suggest subterranean habits.</p> <p>Alate queens were collected in three of 50 canopy fogging samples from the ALAS project at La Selva (http:// viceroy.eeb.uconn.edu/ ALAS / ALAS.html): 8 October and 10 November 1994 and 28 December 1999 (mid to late wet season).

Metalasius myrmidon Boudinot & Borowiec & Prebus 2022, comb.nov.
No full textSpecies Metalasius myrmidon (Mei, 1998) comb.nov. Definition (worker). 1. With character states of Metalasius. 2. Dorsal mandibular groove absent (Note 1). 3. Ventromedial base of mandible without trough or impression (Note 2). 4. Maxillary palps short, exceeding hypostomal margin but not reaching postgenal bridge midlength. 5. Maxillary palpomere 3 longest, 4 shorter but as long as 5 and 6 together (Note 3). 6. Clypeus, in lateral view, convex and weakly bulging anteriorly (Note 3). 7. Anterior tentorial pit situated lateral to midlength of the epistomal suture. 8. Lateral hypostomal carina absent (Note 4). 9. Compound eyes absent, reduced or vestigial, with at most 9 ommatidia (Note 5). 10. Propodeal spiracle situated distinctly in lower half of propodeum (Note 6). 11. Legs almost entirely devoid of standing setae (Note 3). 12. Petiolar node weakly inclined anteriorly, node well-developed, squamiform (Note 7). Notes on definition: Note 1. The dorsal mandibular groove is discernable in all examined Lasius and Prenolepis genus group taxa. Note 2. Presence of a trough on the ventromedial base of the mandible is a newly detected synapomorphy of the core Prenolepis genus group. The impression is enhanced when the ventromedial mandibular margin is carinate and/or produced medially, and best seen when the mandibles are open and with the head in lateral anteroventral view. The trough may be reduced or absent in some species. Note 3. Previously included in the original diagnosis of the species M. myrmidon by Mei (1998). Note 4. The lateral hypostoma is usually delimited by a carina, which is discontinuous with the medial hypostomal lamina. Among formicines, the lateral hypostomal carina is absent only in Acropyga (some species) and Brachymyrmex, both genera outside of Lasiini. Note 5. The specimens, which were available for examination had 5–8 ommatidia; the maximum ommatidium count is from Mei (1998, p. 178). Note 6. Alowered propodeal spiracle appears sporadically replicated in only a few Prenolepis genus group members. Note 7. The petiolar node is strongly inclined anteriorly in the core Prenolepis genus group. Comments. Metalasius myrmidon is uniquely identified among the Lasiini by absence of the dorsal mandibular groove and lateral hypostomal carina, short and broad third antennomere, mid-set compound eyes (when present), which are reduced to at most 9 ommatidia and near complete absence of standing setae on the head. High magnification may be required to evaluate the lateral hypostoma.Published as part of Boudinot, Brendon E., Borowiec, Marek L. & Prebus, Matthew M., 2022, Phylogeny, evolution, and classification of the ant genus Lasius, the tribe Lasiini and the subfamily Formicinae (Hymenoptera: Formicidae), pp. 113-151 in Systematic Entomology 47 on page 141, DOI: 10.1111/syen.12522, http://zenodo.org/record/597534
Compound-specific carbon isotope results from the SH#1 core analyzed and processed at University of Colorado Boulder
No full textThis data set was used to trace changes in carbon cycling and productivity in the Western Interior Seaway (WIS) through Oceanic Anoxic Event 2 (OAE2; 94 Ma). Samples were present in the SH#1 core, which was recovered in the summer of 2014 near Big Water, Utah (37.158466°N, 111.531947°W). Compound-specific carbon isotope data was produced using gas chromatography-isotope ratio mass spectrometry (GCIRMS) between February 2017 and November 2018. Raw data were used in calculations described in Boudinot et al., (in review) to estimate changes in the carbon isotopic composition of marine DIC and atmospheric CO2, as well as changes in pCO2, throughout OAE2, all of which are outlined in the data file. Assumptions and estimates of environmental conditions impacting these estimated carbon-cycle relevant metrics are presented. These data demonstrate both the methods and outputs of using compound-specific carbon isotope analyses to estimate local and global carbon cycle dynamics during an interval of global change during Earth history.
Specifically, the data file includes (A) core depth in meters of the SH#1 core, (B) the name of the compound identified using GC-MS (in Boudinot et al., 2020, Neritic ecosystem response to Oceanic Anoxic Event 2 in the Cretaceous Western Interior Seaway, USA. Palaeogeography, Palaeoclimatology, Palaeoecology, 546, 109673), (C) the calibrated mean carbon isotopic composition of the compound in per mil relative to VPDB, (D) the preparation undertaken prior to analysis on GC-IRMS (i.e., either having undergone urea adduction or not), (E) the carbon isotopic composition of carbonate from the same depth as presented in Jones et al. (2019, Astronomical pacing of relative sea level during Oceanic Anoxic Event 2: Preliminary studies of the expanded SH#1 core, Utah, USA. GSA Bulletin, 131 (9-10): 1702–1722) or as analyzed in Boudinot et al. (in review) (described in methods, indicated in figures), (F) the analytical standard deviation of the carbon isotopic composition of compounds based on either duplicate analysis, or on the predicted standard error based on the calibration ("true_d13c_pred_se" in isoprocessor), (G) the number of duplicate compound-specific analyses, with NA indicating that only one analysis was performed and thus the predicted standard error based on the calibration was used to estimate the standard deviation, (H-I) the minimum and maximum net carbon isotope fractionation during carbon fixation and biosynthesis for the autotroph responsible for each lipid synthesis, in per mil, (J-L) the minimum, maximum, and average fixed inorganic carbon pool carbon isotopic composition estimated using the equations presented in Boudinot et al. (in review), (M) temperature estimate in degrees kelvin, (N) the calculated temperature-dependent carbon isotope fractionation of CO2 with respect to bicarbonate in per mil, (O) the carbon isotopic composition of marine DIC based on the carbon isotopic composition of carbonate for that depth in per mil, (P-R) the minimum, maximum, and average carbon isotopic composition of primary photosynthate calculated using the equation described in Boudinot et al.
