Carex siguanabae Jim. Mejias, Acedo, Reznicek & Lois 2023, sp. nov.
No full textCarex siguanabae Jim.Mejías, Acedo, Reznicek & Lois, sp. nov. (Figs. 5–8) Diagnosis: —This new species is similar to Carex chordalis Liebm. (1850: 269) and to C. donnell-smithii L.H. Bailey (1889: 56). Carex siguanabae is easily distinguished from C. chordalis by its glume color (purplish-black in C. siguanabae vs hyaline to light brown in C. chordalis), and by its utricle enervation (nerves not evident in C. siguanabae vs clearly visible in C. chordalis). In addition, C. siguanabae can be distinguished from C. donnell-smithii (under Chater’s (1994) concept) by its glume length (3.9–7.0 mm in C. siguanabae vs 3.1–3.4 mm in C. donnell-smithii) and by the awned tip (1.0–2.0 mm in C. siguanabae vs 0.3–1.0(1.3) mm in C. donnell-smithii). Type: — EL SALVADOR: Department of Chalatenango: El Pital: Road between Río Chiquito and El Pital, cloud forest with Pinus spp., wet road banks, 14.38146 N 89.129035 W, 2630 m, 29 September 2019, P . Jiménez-Mejías & G. E. Rodríguez Palacios 7ES-PJM19 (Holotype: UPOS! (Figs. 5–7); isotype: MA!). Cespitose, rhizome covered with short yellowish to stramineous hairs. Stems 100–120 cm tall, 0.2–0.3 mm wide at the middle, smooth, trigonous, sides concave below the inflorescence, reddish to brown at the base. Leaves with well-developed blades, the largest ones ± 135 cm × 6.6–7.3 mm, equaling or exceeding the stems, linear, light reddishbrown at the base, W-folded, sheaths orangey-brownish. Inflorescence racemose, usually lax, 18–30 cm long, with 25–60 androgynous spikes, spreading; lowermost bract 15–20 cm × 4.9–7.9 mm, shorter than the inflorescence, soft, green to dark green, W-folded, sheathless or with a short sheath <3 mm. Spikes 4.8–6.7 cm × 3.8–5.2 mm, linear, the distal 1/4 segment staminate, with about 50– 90 female flowers, peduncles smooth, often much longer than the spikes. Female glumes 3.9–7.0 × 0.7–1.3 mm, lanceolate, purplish-black, long awned, awn 1.0–2.0 mm long, ciliate, with hyaline margins absent. Stigmas 3, brownish. Utricles 3.9–4.6 × 0.6–1.2 mm, elliptical, straight or slightly curved, greenish-brown, smooth, nerves not evident, contracted in the apex into a 1–1.8 mm long beak, smooth, bifid, the sinus half the length of the beak. Achenes 1.8–2.9 × 0.8–1.4 mm, ovate to elliptic, trigonous. Habitat and distribution: —This species is distributed in the Central America Cordillera at the border between El Salvador and Honduras, although it may possibly inhabit Guatemala too. It occurs in montane forests, on river shores and open places (forest clearings or roadsides) between 1500 to 2500 m altitude. Phenology: —Flowers and fruits were collected between the end of February and May. Etymology: —The name Carex siguanabae refers to a local mythological creature well-known in Salvadoran folklore, “La Siguanaba”. It is represented as a long-haired woman with a terrifying face. The legend says that Siguanaba waits for men next to rivers and roads (both places where C. siguanabae grows), and then scares them to madness. Observations:— Carex siguanabae can be easily identified by the morphology of its glumes. It has one of the longest glumes in the section Fecundae, up to 7 mm long. It is also different from all the other species of the section by its extremely long and ciliated awns.

Carex orothanatica Lois, Acedo, Reznicek & Jim. Mejias 2023, sp. nov.
No full textCarex orothanatica Lois, Acedo, Reznicek & Jim.Mejías, sp. nov. (Figs. 2–4) Diagnosis:— The Costa Rican Carex orothanatica is similar to the Guatemalan endemic C. tojquianensis Standley & Steyermark (1953: 64). Both taxa clearly differ in the morphology of the utricle beak, bifid in C. orothanatica vs. truncate in C. tojquianensis, and by the color of its glumes, purplish-black in C. orothanatica vs. dark brown in C. tojquianensis. This new species is also similar to the much larger Carex cortesii Liebmann (1850: 268), endemic from Mexico. Both species clearly differ by leaf dimension, 30–40 cm × 4–5 mm in C. orothanatica vs often longer than 100 cm long and 7–8 mm wide in C. cortesii, the number of spikes of the inflorescence, lower than 10 in C. orothanatica vs higher than 20 in C. cortesii, wider and longer utricles in C. orothanatica, 3.3–3.5 × 1.8–2.0 mm than in C. cortesii, 2.2–2.5 × 1.1–1.3 mm. Type:— COSTA RICA: Province of Cartago: Cordillera de Talamanca: Cerro de la Muerte, Pan-American Highway, 5 km above Villa Mills (about 8 km above Nivel) 9°34’N 83°45’W, crevices in rock ledges and on Paramo, 3400–3500 m, 25 July 1949, R. W . Holm & H. H. Iltis 563 (Holotype: A! (Figs. 2–4); isotype: P!). Cespitose, rhizomes densely covered with short yellowish to stramineous hairs. Stems 25–40 cm tall, ± 0.15 mm wide at the middle, smooth, trigonous, sides concave below the inflorescence, reddish-brown at the base. Leaves with welldeveloped blades, largest ones 30–40 cm × 4–5 mm, usually shorter than the stems, linear, subcoriaceous, reddishbrown at the base, W-folded, margin slightly revolute; ligule 0.3–0.4 mm long, acute, orangey-brownish; sheaths orangey-brownish. Inflorescence racemose, 5.0–7.0 cm long, with 7–9 androgynous spikes, spreading or dropping; lowermost bract 5.5–7.5 cm × 2–3 mm, slightly longer than the inflorescence, subcoriaceous, W-folded, sheathless or with a short sheath <3 mm. Spikes 2–3 cm × 5–6 mm, linear to oblong, densely flowered, the distal 1/4 staminate, unbranched, with about 120– 150 female flowers, peduncles smooth, mostly equal or longer than the spikes. Female glumes 3.8–4.0 × 1.6–1.7 mm, ovate to suborbicular, purplish-black with a light green middle longitudinal strip, excurrent into a 0.4–0.5 mm awn, hyaline margins extremely narrow or absent, when present it is along the entire glume length. Stigmas 3, brownish. Utricles 3.3–3.5 × 1.8–2.0 mm, suborbicular, glabrous, brownish-red, smooth, nerveless, contracted at the apex into a 0.3–0.4 mm long beak, smooth, bifid, with the teeth slightly divergent, the sinus between teeth as deep as the whole beak length. Achenes 1.6–1.8 × 0.9–1.1 mm, ovate to elliptic, trigonous, cuneate to round at the base; style strongly lignified, leaving a long cylindrical, 0.2 mm long remnant at the apex of the achene. Habitat and distribution: —Known only from two collections and one recent iNaturalist observation that confirms the presence of the species (https://www.inaturalist.org/observations/111517173) at Cerro de la Muerte, on the western slopes of Cordillera de Talamanca, growing at an altitude of 3400–3500 m in páramo vegetation. Phenology:— Flowers and fruits were collected at the end of July. Etymology: —The epithet “ orothanatica ” is formed by the ancient Greek “ oros ”, mountain, and “ thanatica ”, in reference to “ Thanatos ”, the Death. It refers to the toponym of “Cerro de la Muerte”, which means Mountain of Death, where the type material was collected. Paratype:— COSTA RICA: Province of San José: Direct line from Hotel La Georgina to Cerro Frío of the Cerro Buenavista complex (Cerro de la Muerte), area with television and radio towers, 9°33’- 34’ N 83 °43’- 46’W, rocky, grassy slope, 3100–3400 m, 20 September 1983, G .

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
