Type locality. 440 m elevation, Peralta, Azua Province, Dominican Republic. Distribution and habitat. Upland southeastern slopes of the Cordillera Central and Sierra Martín García. Under leaf litter and talus in mesic scrub and forests; portions cleared for coffee groves. Locally common. Material examined (112 specimens examined). Dominican Republic. GTW 7072 b(1), 300 m, Barrera, Azua Province; UF 216481 (5), 440 m, Peralta, Azua Province; UF 23177 (5), 1 km S of Peralta, Azua Province; UF 216615 (59), 560 m, 1 km SE of Peralta, Azua Province; UF 216620 (18), 170 m, 1 km E of El Tablazo, San Cristóbal Province; UF 216618 (24), 220 m, 13 km NW of Sabana Grande de Boyá, San Cristóbal Province [not found]. Description. Shell thin, almost translucent, conic. Maximum adult size: 17.6 mm, decollate. Minimum adult size: 13.0 mm, decollate. Adult shell usually not decollated, protoconch of 1.5 minute, smooth whorls, white with dark brown suture at apex, occasionally with faint tan, central band, demarcation between protoconch and teleoconch not well-defined. Teleoconch of 5 whorls. Axial sculpture of final whorl of numerous (170–200) very fine, narrowly spaced, flattened threads. Shell with regularly spaced growth stoppage marks, axial threads preceding marks microscopic and densely packed. Spiral sculpture of final whorl outside of umbilicus of 30–40 fine threads, nearly same width as axial threads. Intersections of axial and spiral sculpture minutely beaded. Umbilicus with ca. 15 weak spiral cords distributed across entire surface. Suture narrow, deep. Tufts composed of 1–3 slightly enlarged, irregularly spaced, almost blade-like axial threads. Aperture teardrop-shaped, lip double, rarely single. Inner lip erect, barely to prominently exserted and often fused to outer lip. Outer lip expanded, narrower facing umbilicus, slightly recurved abaperturally. Narrowly solute with previous whorl. Prominent posterior auricle, often hook-shaped. Smaller, somewhat undulating auricle also present at 8 o’clock position. Color pattern complex and variable. Base color white with tan spots between tufts, occasional dark band below tufts, and 6–9 narrow, spiral bands usually broken into spots, some specimens with irregular tan markings as well. Inner lip and both sides of outer lip with dark brown markings. Tufts white. Operculum corneous, paucispiral, lacking calcification. Variation in specimens. Shells vary in the degree of coloration but most are quite pale overall. The Barrera specimen is much darker. Other characteristics are rather constant. Comparison with other species. This species is similar in coloration to P. salleanus and P. isabellinus. All three species are allopatric and are distributed along the southern ranges of the island. Parachondria salleanus has a single, scarcely reflected lip; both P. daedalus and P. isabellinus have a widely expanded, double lip. Parachondria daedalus differs from P. isabellinus is having much finer sculpture (140–150 axial threads in P. isabellinus, 170–200 axial threads in P. daedalus). Parachondria daedalus is more rotund and has a lower spire than P. isabellinus. Remarks. One specimen contains the remains of a web within the umbilicus (fig. 3 D). It is very similar to a web found in Abbottella nitens Watters, 2013, from the eastern Dominican Republic that contained a pseudoscorpion (Watters, 2013). This suggests that the pseudoscorpion may have been living within the umbilicus in a commensal association with the snail. Etymology. Gr. daidalos, dappled, spotted.Published as part of Watters, G.

The summertime diurnal cycle of precipitation derived from IMERG
No full textThe Integrated Multi-satellitE Retrievals for GPM (IMERG) precipitation product derived from the Global Precipitation Measurement (GPM) constellation offers a unique opportunity of observing the diurnal cycle of precipitation in the latitudinal band 60°N-S at unprecedented 0.1° × 0.1° and half-hour resolution. The diurnal cycles of occurrence, intensity and accumulation are determined using four years of data at 2° × 2° resolution; this study focusses on summertime months when the diurnal cycle shows stronger features. Harmonics are fitted to the diurnal cycle using a non-linear least squares method weighted by random errors. Results suggest that mean-to-peak amplitudes for the diurnal cycles of occurrence and accumulation are greater over land (generally larger than 25% of the diurnal mean), where the diurnal harmonic dominates and peaks at ~16-24 LST, than over ocean (generally smaller than 25%), where the diurnal and semi-diurnal harmonics contribute comparably. Over ocean, the diurnal harmonic peaks at ~0-10 LST (~8-15 LST) over open waters (coastal waters). For intensity, amplitudes of the diurnal and semi-diurnal harmonics are generally comparable everywhere (~15-35%) with the diurnal harmonic peaking at ~20-4 LST (~3-12 LST) over land (ocean), and the semi-diurnal harmonic maximises at ~5-8 LST and 17-20 LST. The diurnal cycle of accumulation is dictated by occurrence as opposed to intensity

Paradoxipoma enigmaticum Watters, 2014, new species
No full textParadoxipoma enigmaticum new species Figures 8 A–E, 12 A Type material. UF 479320, holotype (figs. 8 A, B); UF 479321 (3), paratypes (figs. 8 C, D), from type locality; UF 479322 (1), paratype (fig. 8 E), Rockville Quarry, Gracy Rock Hill. Type locality. Limestone hill on south side of Sibun River at Cedar Banks, Belize District, Belize, 50 m. Distribution and habitat. Known only from limestone outcrops in the vicinity of Gracy Rock Hill in Belize District, Belize, at ca. 50 m elevation. These limestone knolls extend south of the type locality for ca. 8 km. Conservation. None of the localities are protected; one of the two known sites is a quarry. Other material (specimens examined: 172). Belize. Belize District: UF 207315 (83), Rockville Quarry, Gracy Rock Hill; UF 207514 (89), limestone hill on south side of Sibun River at Cedar Banks, 50 m. Description. Shell conic, turbinate, thin, translucent, adnate. Largest adult specimen seen 9.6 mm (nondecollate). Protoconch retained in adult, 1.5 whorls, smooth, prominent, flattened, dark brown or tan with a dark top, demarcation between protoconch and teleoconch very indistinct. Teleoconch of 3.5 rounded whorls with a blunt angle at the level of the juncture with the peristome. Umbilicus wide, open. Spiral sculpture of ca. 17 low threads, distantly spaced below suture, becoming progressively closer together towards the angle; the threads abruptly end at the angle and are absent on the base except for very faint signs of a few cords in the umbilicus. Axial sculpture of numerous very fine, very closely spaced lamellae. Intersections of axial and spiral sculpture minutely beaded or fenestrated. Suture strongly indented, smooth. Aperture somewhat triangular. Inner lip absent. Outer lip very narrow, reflection scarcely apparent, adnate with previous whorl. Base color dingy white or tan, earlier whorls often more darkly colored than last whorl. Many specimens show varying degrees of tan spiral banding composed of three bands above the angulation and one or two below; bands often broken into dots or dashes; bands visible in aperture and on outer lip. Opercula known from only two specimens, both incomplete, but having the remains of a multispiral, narrow, calcareous lamella with a broad sulcus between the whorls. Radula and anatomy unknown. Variation in specimens. Specimens vary primarily in the intensity of the color pattern. Comparison with other species. Specimens resemble juvenile individuals of other species. The angular whorls and lack of spiral sculpture on the base characterize this species. Remarks. This species seems to be narrowly endemic to a series of limestone knolls that occupy ca. 50 km 2. It co-occurs with H. gruneri and H. kuesteri but is clearly distinguishable from juveniles of those species. Etymology. L. aenigma, inexplicable, mystery.Published as part of Watters, G.

Gouldipoma coltrorum Watters, 2014, new species
No full textGouldipoma coltrorum new species Figure 5 A–L, 12 D, 13 A, L Type material. UF 479664, holotype (figs. 5 A, B); UF 479666 (5), paratypes, from type locality; UF 479665 (3), paratypes (figs. C – H), Río Escobas, 60 m. Type locality. 4 km N of Morales, Izabal Department, Guatemala. Other material (specimens examined: 102). Guatemala. Izabal Department: UF 190586 (19), Río Escobas, 60 m; UF 9151 (46), UF 213711 (25), Puerto Mátias de Gálves [Santo Tomás de Castilla]; GTW 16018 a (12), entrance to Cuevas del Silvino near Morales. Distribution and habitat. Records are for each end of Cerro San Gil, although it undoubtedly occurs in the intervening range as well. Like G. chrysostiria (below), it appears to occupy the hills bordering a broad river valley, in this case the Río Motagua valley (famous as the only source of jade in Central America). Conservation. The species’ known range is mostly in the Cerro San Gil Ecological Reserve. It may occur in the Cuevas del Silvino National Park as well. Description. Shell conical, high-spired, thin, translucent, last 1 / 8 whorl solute. Smallest adult specimen seen 6.5 mm in length, largest 14.5 mm, average 10.7 mm (decollate). Protoconch usually lost in adult, 1.5 large, rounded, smooth, pale whorls, not clearly demarcated from teleoconch. Teleoconch of 3.5 – 4.5 rounded whorls. Umbilicus small, mostly occluded by outer lip. Spiral sculpture variable: on some specimens only apparent as scalloped margins of axial lamellae, which fade away towards the umbilicus; in others apparent as ca. 26 widely spaced threads. No delimiting cords in the umbilicus. Axial sculpture of numerous (ca. 100) fine, low, narrow lamellae. Suture strongly incised. Tufts absent but the axial lamellae may render the suture minutely serrate. Aperture nearly circular. Inner lip smooth, inconspicuous, scarcely exserted. Outer lip widely reflected perpendicular to whorl, evenly expanded except where joined to previous whorl, widely auriculate posteriorly, composed of numerous coarse lamellae. Base color orangish-tan, some specimens with faint, narrow tan bands; bands are not continuous over adapertural face of peristome. Inner lip (or just within) and first lamella of outer lip usually lavender, rose, or tan. There is a narrow band of the same color just before the abapertural side of the peristome. Operculum multispiral with a calcareous, erect but low reflected lamella. Radula and anatomy unknown. Animal pale cream or tan (fig. 13 A); middle portion of antennae yellow, tips pale tan; area between bases of antennae darker brown, patternless. Eyes black. Variation in specimens. The color and intensity of the colored ring behind the peristome varies from dark rose to barely perceptible. Sculpture varies from almost smooth to minutely scalloped. Populations vary substantially in size: specimens from Río Escobas average 12.6 mm in length whereas those from Puerto Mátias de Gálves average only 8.6 mm. Comparison with other species. Other species also have a colored ring behind the peristome: G. thomasi and G. terecostatum. Gouldipoma coltrorum differs from G. thomasi in the broadly expanded outer lip. It differs from G. terecostatum primarily in possessing spiral sculpture, which is absent in G. terecostatum. Remarks. With these snails’ apparent proclivity for living in broad river valleys bounded by limestone ranges, it might be worthwhile investigating such habitats elsewhere. The valleys of the Río Sico and Río Patuca in Honduras seem likely candidates for yielding new taxa. Etymology. Named for José and Marcus Coltro of Femorale, Inc. who generously donated material of this species and others from Central America.Published as part of Watters, G.

Evaporation in action sensed by multiwavelength Doppler radars
No full textThis work documents a rain case dominated by evaporation which occurred at the Atmospheric Radiation Measurement site in Oklahoma on 15 September 2011. A recently developed algorithm, applied to radar Doppler spectra measured at Ka and W band, provides the vertical evolution of binned drop size distributions (DSDs) and of the vertical wind. Such retrieved quantities are used in connection with relative humidity (RH) profiles to derive evaporation rates and atmospheric cooling rates. In addition, in regions of stationarity and of light rain, when other microphysical processes are negligible, the presented case study suggests the possibility of retrieving RH profiles from the vertical evolution of the drop size distributions. The key is to characterize the gradient of the rain mass flux between successive levels. Such signal is particularly weak and can be enhanced thanks to a substantial averaging of the retrieved DSD over approximately 5 min and 250 m (eight range gates). The derived profile agrees with the retrieval from coincident Raman lidar observations within a 10% RH difference. These results suggest that other rain microphysical processes could be studied by combining the radar-based DSD retrieval with ancillary RH observations
