No full textThe zip file contains folders, scripts, and data necessary to reproduce the analysis and figures. Once unzipped, all scripts and data can be opened and run in RStudio with the "RStudio Project Leaf-level tradeoffs oaks AZ.Rproj" file. All folders with data (folders proceeded by “input_”, the “gen_data” folder, and the “hipp_etal” folder) contain separate readme files that document the individual files in that folder. See the primary README.txt for more information.This dataset and RStudio project includes all processed data, most raw data, and R scripts needed for analysis and figure construction included in the manuscript Fallon and J. Cavender-Bares 2018 (Fallon B. and J. Cavender-Bares. 2018. Leaf-level trade-offs between drought avoidance and desiccation recovery drive elevation stratification in arid oaks. Ecosphere. in press). We investigated whether oak species in the Chiricahua Mountains were 1) elevationally stratified, 2) whether that stratification was correlated with temperature minima, maxima, and water availability, 3) if physiological tolerances to freezing or drought stress correlated with elevation ranges, and 4) if traits important to local (elevation) distributions were correlated with climatic values of the wider species ranges. Data were collected at field sites from wild, adult trees in the Chiricahua Mountains, Arizona, USA from 2014-2015.This research was done with funding to B. Fallon from the Southwestern Research Station (SWRS, American Museum of Natural History), the University of Minnesota Charles J. Brand, Carolyn Crosby, and Dayton Bell Fellowships, and the Department of Plant and Microbial Biology. Additional funding was provided by NSF Award 1146380 (J. Cavender-Bares PI).

(Grand Bahama I.; Eleuthera I.); Turks & Caicos Is.; Dominican Republic; Puerto Rico; Honduras (Vivorillo Cays); Antigua; Guadeloupe; Martinique; St. Vincent & the Grenadines; Granada; Barbados; Trinidad & Tobago (Tobago I.); Venezuela (Tortuga I.); Netherlands Antilles (Curaçao I.); and French Guiana. Specimens reported as <i>Cerodrillia perryae</i> in Jong & Coomans (1988: 112) are believed to be this species on the basis of a photograph of a specimen from Curaçao I. provided by M. Faber (pers. comm. 22 Apr 2011). <i>Douglassia antillensis</i> is associated with coral reefs and has been reported from 7–32 m depths on carbonate sand or carbonate sand and coral rubble in reef swales or pockets. Only dead-collected specimens occur at greater depths from off Palm Beach Co. (55 m), from off Barbados (128– 183 m), off Curaçao (244–274 m), and off French Guiana (57–103 m), perhaps transported there from shallower depths by currents.</p> <p> <b> Description. <i>Shell</i></b> small (to 17.7 mm), stoutly fusiform, glossy, truncated anteriorly, whorls up to 11, but more commonly around 9; last whorl approximately 63% of total length; whorls convex with bulging ribs; shell apex acutely pointed. <i>Protoconch</i> conical, of approximately 2½–2¾ glassy, smooth whorls, the exact number difficult to determine because the tip of the first is partially immersed in the second; color golden brown. <i>Axial sculpture</i> of prominent convex ribs, obsolete or absent in sulcus, most prominent and widest on whorl periphery a little below mid-whorl, and evanescent on the shell base below periphery. Rib crests round at whorl periphery but ridged in the sulcal region where ribs are narrower and slightly hooked to the left reflecting outline of anal sinus. Ribs number 8–9 on penultimate and 5–7 on the body whorl to the varix. Axial growth striae present on shell surface, curved in the region of the anal sulcus. <i>Varix</i> located just behind the anal sinus and resembles a cup handle when viewed ventrally. <i>Anal sinus</i> on shoulder adjacent to suture, deep, U-shaped, offset from the shell axis by parietal callus; edge of inner lip of sinus flared. <i>Spiral sculpture</i> of fine threads or ridges, barely visible below the periphery of last whorl, becoming stronger anteriorly on base and anterior fasciole. <i>Outer lip</i> thin, projecting out from the varix; with an irregular axial fold or thin axial rib; edge flexed out at anal sinus, waved below; with a shallow stromboid notch. <i>Inner lip</i> wide, margined, thick anteriorly, thinner on parietal wall, with a thick callus that forms one side of the anal sinus. Lip and callus edge raised by visible layers of successive deposition, especially in more mature specimens. <i>Anterior canal</i> short, open, unnotched, slightly curved to the right viewed ventrally, canal tip with a slightly flared marginal lip. Anterior fasciole not swollen; with about 6 faint spiral ridges. <i>Color</i> shell base dingy white, with a light to dark golden brown band just below body whorl periphery, visible as a narrow band at spire sutures; rib crests dingy white; band’s posterior edge fades to the shell’s base color; the anterior edge is more distinct.</p> <p> <b> Remarks. <i>Taxonomy</i>.</b> <i>Douglassia antillensis</i> has all the key characteristics of the genus: a concave sulcus with obsolete or absent ribs, a 2½- to 2¾-whorl protoconch, spiral microsculpture confined to the base, and a cuphandle-like varix positioned immediately behind the anal sinus. It is the commonest <i>Douglassia</i> in the Antilles, often misidentified as <i>Cerodrillia perryae</i> (Bartsch & Rehder, 1939) in museum collections. Many of the published reports of <i>C. perryae</i> from outside of Florida are also likely this species but cannot be confirmed without accompanying photographs. A list of reports of <i>C. perryae</i> that are likely this species is given in the synonymy list under that species. <b> <i>Variability</i>.</b> The average total length of 210 measured specimens is 9.72 mm (2.8–17.7 mm); the average W/ L ratio of 0.449. Given its relatively wide dispersal, it is fairly uniform in its morphology and color pattern, although there are some regional differences in color—those from the northern limit of its distribution, e. g. Grand Bahama I., appear to be lighter in color, and those from the southern limit (French Guiana) a mostly solid orange-brown color with white rib crests. Specimens are shown from various localities in Plate 58. <i> <i>Identification.</i> Douglassia antillensis</i> most closely resembles <i>D. enae</i> Bartsch, 1934 but differs principally in possessing less angular shoulders, most conspicuously on the last whorl. It also differs in coloration; the central band in <i>D. antillensis</i> tends to be less distinct on its adapical (posterior) margin, and its protoconch is dark, similar to the color of the band. <i>Douglassia enae</i> has a more distinct adapical margin on its central band, and a light colored protoconch. Although their ranges overlap, <i>D. antillensis</i> is reported from shallower water. <i>Douglassia antillensis</i> is often misidentified as <i>C. perryae</i> but is stouter, has 2½–2¾ protoconch whorls, not 1¾–2, and a slightly different color pattern. Because it is stouter, its W/ L ratio is greater (Average W/L = 0.449 for 210 specimens of <i>D. antillensis</i> versus 0.392 for the 17 specimens of <i>C. perryae</i>). The color pattern of <i>D. antillensis</i> is consistent among specimens, even across its much larger range than <i>C. perryae</i>. The latter varies in pattern; i.e., the central band is more variable in width, or even absent. <i>Douglassia antillensis</i> differs from <i>D. moratensis</i>, new species in having less convex body whorl, less prominent ribs on the shoulder, and a different color pattern. <i>Douglassia antillensis</i> has also been confused with <i>C. thea</i> (Dall, 1884), but that species’ spire is taller, color a uniform brown, and ribs shorter and more oblique.</p> <p> <b>Etymology.</b> The Antillean <i>Douglassia</i>. Although not strictly confined to the Antilles, <i>D. antillensis</i> appears to be quite common and widespread in this region, especially in the Windward Is.</p>Published as part of <i>Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1)</i> on pages 130-133, DOI: 10.11646/zootaxa.4090.1.1, <a href="http://zenodo.org/record/263299">http://zenodo.org/record/263299</a>

Fenimorea contracta Fallon, 2016, new species
No full textFenimorea contracta, new species (Plate 72) Type material. Holotype 15.3 x 5.4 mm, R. Black! aboard R/V Ike, 20 Apr 1967 (UF 170316). Type locality. NE of Contoy Light, Quintana Roo, Mexico, in 100 fms [183 m]. Range and habitat. Known only from the holotype. Description. Shell small (to 15.3 mm total length), narrowly fusiform, surface glossy smooth; whorls convex, number 8 ½, last whorl 57 % of total shell length; ribs the predominant sculpture; aperture narrow. Protoconch of 2 smooth round whorls. Axial sculpture of bold straight ribs that run from suture-to-suture on spire, evanesce on base, aligned on all but last 2 whorls; ribs number 5 on penultimate, 4 on last whorl to varix, intercostal space wider than ribs. Varix narrow, approximately ⅓-turn from edge of outer lip. Spiral sculpture of very fine threads or grooves, intersected and made jagged by microscopic growth striae; threads spaced more closely in sulcus. Sulcus not distinct, demarcated where ribs are slightly narrowed, recurved, and slightly reduced in height. Outer lip thin, somewhat flattened from varix to lip’s edge; with 5 irregular post-varical folds; edge of lip from anal sinus to anterior canal relatively straight, not curved, smooth not toothed; stromboid notch absent. Anal sinus a deep Ushaped notch next to the suture; with a lobe on the parietal side, and a callus thickening around the apex of the sinus. Inner lip anteriorly pinched up along canal, widest on columella, narrow on parietal wall, and thickened into a lobe near the suture posteriorly. Anterior canal of moderate length for the genus, open, notched at its end; fasciole not swollen. Color light saffron overall with golden brown patches confined to intercostal spaces. Remarks. Taxonomy. Fenimorea contracta has the characteristic shell surface microsculpture of Fenimorea, ribs suture-to-suture, and a deep U-shaped anal sinus. Its narrow varix, narrow sulcus, and anterior canal, which is of moderate length are typical of offshore species (as exemplified by F. j a ne t a e Bartsch, 1934). Near shore species, such as F. fucata (Reeve, 1845), generally have broad varices, wide sulci, and short anterior canals. Identification. Fenimorea contracta is most similar to F. crocea, new species in color, size, but differs in having fewer ribs and narrower profile (W/L of holotypes = 0.353 versus 0.386). The narrow profile and presence of only five ribs on the single specimen is unique enough to distinguish this taxon from its congeners and merit its description as a new species. Etymology. The Narrow Fenimorea. Named for its narrow form.

Moore! Sep 1964 (USNM 900240). Range and habitat. Louisiana; Alabama; W Florida (off Escambia Co.; off Okaloosa Co.; off Levi Co.); Florida Keys (off lower Keys). Most depth reports are between 50–100 m, exceptionally as shallow as 26 m and deep as 183 m. Description. Shell small (to 11.4 mm), stoutly fusiform, truncated anteriorly; up to a total of 8 whorls, moderately convex to swollen, sutures impressed, undulant over and under rib terminations, last whorl large, approximately 64 % of total shell length. Protoconch of approximately 1 ½– 1 ¾ glossy-smooth, round whorls. Axial sculpture of prominent, oblique ribs that run suture-to-suture and evanesce low on the shell base, their interspaces wider than the ribs; 5–8 ribs on penultimate, 3–6 on last whorl to the varix. Rib crests round. Ribs tend to align but vary among individuals from fully aligned to offset, especially on last whorl. Growth striae microscopic. Varix is an expanded last rib, within ⅓-turn of outer lip’s edge, not always in alignment with previous whorl’s rib. Spiral sculpture of closely spaced threads over entire teleoconch, made jagged by growth striae; somewhat coarser threads are more widely spaced on anterior fasciole. Sulcus absent; somewhat reduced and slightly curved ribs are the only trace of the anal sinus. Outer lip thin, usually without axial folds; edge forming a low arc from anal sinus to end of the anterior canal. Stromboid notch weak. Anal sinus a wide but shallow indentation of outer lip’s edge when shell is viewed laterally; aperture an inverted V-shape at the junction of the inner and outer lips when shell is viewed ventrally; callus present on parietal wall, and inside of outer lip in sinus of older specimens. Inner lip recumbent, margined and edge slightly erect on anterior canal, not margined on parietal wall, ending in a low callus posteriorly. Anterior canal short, wide, open, and turned to the left when viewed ventrally; notch present on its end; anterior fasciole not swollen. Color off white with a variable central brownish orange band that may cover the entire whorl except for rib crests, or be reduced to a just the rib interspaces. Remarks. Taxonomy. Bellaspira aurantiaca has all the principal characteristics of the genus, including the typical anal sinus, ribs suture-to-suture, varix represented by an enlarged rib, and spiral incised lines overall. Unique to this species is the presence of relatively coarse spiral threads (consequently shell surface is not glossy) and brownish-orange shell color pattern. Variability. The average length of 19 measured specimens is 8.24 mm (4.2–11.4 mm) and their average W/L is 0.460. Observed variation occurs principally in color and the arrangement of ribs. Color varies from pure white to almost completely brownish orange. The brownish orange may appear in a solid spiral band, or be confined to just the rib interspaces. Rib arrangement may be strictly aligned as is usually the case in B. pentagonalis (Dall, 1889), or unaligned. Identification. This species is recognizable by its brownish orange color and whitish ribs. It differs from B. pentagonalis in possessing coarser spiral microsculpture (the shell is not as glossy) and a different coloration. From B. amplicostata, new species, it differs in possessing fewer and narrower ribs, and a different coloration. Etymology. The Orange-colored Bellaspira, from the Latin adjective aurantiacus, feminine aurantiaca, meaning orange-colored. Named after the unique and outstanding feature of this species—its color.Published as part of Fallon, Phillip J., 2016, Taxonomic review of tropical western Atlantic shallow water Drilliidae (Mollusca: Gastropoda: Conoidea) including descriptions of 100 new species, pp. 1-363 in Zootaxa 4090 (1) on page 26, DOI: 10.11646/zootaxa.4090.1.1, http://zenodo.org/record/26329
