No full textStegonotus melanolabiatus Ruane et al., 2017:18 Taxonomic status. Valid. Synonyms. None. Original name. Stegonotus melanolabiatus Ruane et al., 2017:18. The species name is a descriptive adjective formed from the Greek melano and the Latin labia, meaning dark lips. It was selected to highlight the presence of dark coloration on the labial scales. The species description was presented in English. Type specimens. Holotype: AMS R115343 (Fig. 33 A–E, Table 1; Ruane et al. 2017: Fig. 7), an adult male. Paratypes: AMS R 122906 (Fig. 33 F–H), an adult male. AMS R115361 (Fig. 33 I–K), unsexed. Our own examination of this specimen ascertained by the presence of follicles that it is a female. AMS 115320 (Fig. 33 L–N), unsexed. Our own examination of this specimen ascertained by the presence of the m. retractor penis magnus that it is a male. Type localities. Holotype: Doido, Chimbu [now Simbu] Province, Papua New Guinea, elev. 1300 m (ca. 6.5500°S, 144.83°E). Paratypes: AMS R 122906, Waro, Southern Highlands Province, Papua New Guinea, elev. 550 m (ca. 6.5333°S, 143.18°E); AMS R115361 and R115320, Noru, Simbu Province, Papua New Guinea, elev. 1150 m (ca. 6.5833°S, 144.65°E). Collection. All type specimens were collected by Stephen C. Donnellan (South Australian Museum, Adelaide, South Australia) and Kenneth P. Aplin (Smithsonian Institution, Washington, D.C., USA) in April and May 1984. Key characteristics of the type specimens.

According to their specimen list, Ruane et al. (2017: Appendix) included ten specimens of S. melanolabiatus in their analysis. These included specimens from a locality in the recently (2012) formed Hela Province (1 ♀, 1 ♂; erroneously listed as from Southern Highlands Province), Simbu Province (2 ♀♀, 3 ♂♂) and Southern Highlands Province (2 ♀♀, 1 ♂). We have examined all of these specimens personally, and while there is general agreement between our data sets, there are three noteworthy differences (those of Ruane et al. are shown in parentheses). Our data show AMS R115360 with 15-15-15 (17-17-15) dorsals, AMS R 122360 with 17-17-15 (15-15-15) dorsals, and AMS R115321 with 7 (8) supralabials and 8 (9) infralabials. The data for supra- and infralabials is readily verified on our photographs of the specimens and is used for the following calculations. The two other data discrepancies are omitted because of their incongruence. Characteristics include V ♀ = 180–191 (184 ± 4.3), V ♂ = 190–201 (196 ± 4.7); SC ♀ = 89–100 (96 ± 4.9), SC ♂ = 93–100 (95 ± 3.3); SCR ♀ = 0.34, SCR ♂ = 0.33; D = 17-17-15 (n = 6, 75%) or 15-15-15 (n = 2, 25%); SL E = 3+4 (100%); SL = 7 (100%); IL = 8 (100%); IL G = 5. Based on the numbers of ventral scales, there appears to be some sexual dimorphism in that character, with females generally possessing a number of ventrals in the 180s (V mean = 184, only one female with V = 191), whereas males have ventral numbers in the 190s or higher (V mean = 196, two males with V ḵ 200). There does not appear to be any sexual dimorphism in the number of subcaudal scales. Comment. Ruane et al. (2017) considered S. melanolabiatus to be a member of their S. diehli complex.Published as part of Kaiser, Christine M., Kaiser, Hinrich & O'Shea, Mark, 2018, The taxonomic history of Indo-Papuan groundsnakes, genus Stegonotus Duméril et al., 1854 (Colubridae), with some taxonomic revisions and the designation of a neotype for S. parvus (Meyer, 1874), pp. 1-73 in Zootaxa 4512 (1) on page 58, DOI: 10.11646/zootaxa.4512.1.1, http://zenodo.org/record/260757

Processing tomato production is expected to decrease by 2050 due to the projected increase in temperature
No full textThe global production of processing tomatoes is concentrated in a small number of regions where climate change could have a notable impact on the future supply. Process-based tomato models project that the production in the main producing countries (the United States, Italy and China, representing 65% of global production) will decrease 6% by 2050 compared with the baseline period of 1980–2009. The predicted reduction in processing tomato production is due to a projected increase in air temperature. Under an ensemble of projected climate scenarios, California and Italy might not be able to sustain current levels of processing tomato production due to water resource constraints. Cooler producing regions, such as China and the northern parts of California, stand to improve their competitive advantage. The projected environmental changes indicate that the main growing regions of processing tomatoes might change in the coming decades

(2017: Appendix) included four specimens of <i>S. admiraltiensis</i> in their analysis. Of these, one male and two unsexed specimens were collected on Rambutyo, and one unsexed specimen on Los Negros. Given that most of the specimens were not sexed, it is not possible to draw conclusions regarding the distribution of characteristics by sex or about the presence of sexual dimorphism. The characteristics we list here are therefore somewhat limited in their overall description of the species. We consider <i>S. admiraltiensis</i> to be a species with a relatively high ventral scale count (V> 200) with a relatively high number of subcaudal scales (SC> 90; SCR> 0.30). The dorsal count of 17-19-15 is unique among the species of <i>Stegonotus</i>, and its occurrence in a species that also presents dorsal counts of O-17-O (most likely 17-17-15) is unusual. The SL E is most likely 4+5 for the species given that this character tends not to be rarely variable in <i>Stegonotus</i> species. The number of supralabials was eight for all specimens, and among infralabials three specimens had IL = 10, whereas one had SL = 9. Based on the ventral view of the holotype, the sixth infralabial scale barely touches the anterior genial, and we wonder whether this character can be consistently scored as IL G = 6 across all specimens. If so, then this is another unique characteristics of <i>S. admiraltiensis</i> among the species of <i>Stegonotus</i>.</p> <p> <b>Comment.</b> Ruane <i>et al.</i> (2017) compared <i>S. admiraltiensis</i> to <i>S. modestus</i> and <i>S. parvus</i> at length, but without the benefit of having examined the holotype of the former or using the original description of the latter (characteristics of <i>S. admiraltiensis</i> in parentheses): <i>S. modestus</i> has a light neck band (absent), a subcaudal count <90 (> 90), SL E = 3+4 (4+5), and IL G = 4 (6). <i>Stegonotus parvus</i> has a ventral count <180 (> 200), SL E = 3+4 (4+5), and IL G = 4 (6). Furthermore, Ruane <i>et al</i>. (2017) referenced two additional Manus specimens but did not include them in their analysis. We have examined an additional 38 specimens from the Admiralty Islands, which include 15-15-15 (n = 3), 17-17-15 (n = 30), and 17-19-17 (n = 5) dorsal counts, with SL E = 3+4 (n = 16) or 4+5 (n = 20), with subcaudal counts that differ from <i>S. admiraltiensis</i> as defined above. Two specimens have aberrant counts of SL E, with 3+4 on one side of the head and 4+5 on the other. It therefore appears to us as if <i>S. admiraltiensis</i> is not the only species of <i>Stegonotus</i> present in the Admiralty Islands and further research will be needed to ascertain the taxonomy of groundsnakes there.</p> <p> <b> Specimen Type SCR SubC Species Synonym Sex SVL TL TTL V SC Dorsals SCE SL IL ILG Number Status (%) Condition</b> BMNH <i>heterurus</i> LT M 393 89 482 179 80 31 single 17-17-15 3 +4 7 9 4 1946.1.14.95 MZB <i>iridis</i> HT M 713 238 951 201 88 30 paired 17-19-15 4 + 5 8 10 10 Ophi.3306 MSNG <i>keyensis</i> HT M 651 164 815 200 73 27 paired 17-17-15 4 +5 8 9 5 7521 RMNH <i>lividus</i> LT F 444 123 567 197 67 25 paired 17-17-15 3 +4 7 9 4 RENA.325A AMS <i>melanolabiatus</i> HT M 615 192 807 197 92 32 paired 17-17-15 3 +4 7 8 8 R115343 RMNH <i>modestus</i> HT M 656 158 814 200 83 29 paired 17-17-15 3 +4 7 8 4 RENA.324 BMNH <i>modestus greineri</i> HT M 552 162 714 206 86 29 paired 17-17-15 3 +4 7 8 4 1946.1.13.74 BMNH <i>modestus holochrous</i> HT M 537 182 719 195 83 30 paired 17-17-15 3 +4 7 8 4 1946.1.11.40 RMNH <i>modestus rosenbergii</i> HT M 582 178 760 203 80 28 paired 17-17-15 3 +4 7 9 4 RENA.4066 MNHN <i>muelleri</i> HT F 1006 302 1308 217 97 31 paired 17-17-15 4 +5 8 9 4 848 ZMB 9R <i>muelleri samarensis</i> HT M O O O 236 98 29 paired 17-17-15 4 + 5 10 4 4294 8L MTKD <i>parvus</i> ST c O O O O 177 100 36 paired O-17-O 3+ 4 7 O O 876A MTKD <i>parvus</i> ST c O O O O O O O O O 3+4 O O O 876B RMNH <i>parvus</i> NT F 217 75 292 173 87 33 paired 17-17-15 3 +4 7 8 4 RENA.46844 NMW 164 <i>poechi</i> HT F 860 O 200 55+ O paired 19-19-17 4 +5+ 6 9 10 4 23406 + BMNH <i>reticulatus</i> LT F 880 238 1118 201 78 28 paired 17-17-15 4 +5 8 9 4 1946.1.14.87 NMBA <i>sutteri</i> HT M 567 144 711 230 83 27 single 21-21-19 3 +4+ 5 9 10 5 14872 a MTKD 573 is definitely a type specimen of <i>Lycodon magnus</i> Meyer, 1874, which was destroyed in 1945. b ZMB 8794 may be a syntype of <i>L. magnus</i>, but its status is inconclusive at this time. c MTKD 876A and 876B were destroyed in 1945.

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
