Multivariate Quantitative Representativeness and Constituency Analysis of Ecological Observation Networks
Author: Jitendra (Jitu) Kumar ([email protected]), Oak Ridge National Laboratory
Regional and global ecological research networks, representing coordinated and standardized as well as adhoc networks of observation sites, provide valuable observations necessary for ecological modeling and synthesis studies. Studies conducted across observational networks strive to scale up their results to larger areas, trying to reach conclusions that are valid throughout regional, continental, and even global scales. Network representativeness and constituency can show how well conditions at those locations represent conditions elsewhere within a larger area containing the network and can be used to help scale-up results over larger regions.
Representativeness: Euclidean distance between two sites plotted in multivariate environmental space can be used as an inverse measure of multivariate similarity to quantify representativeness. Close sites in environmental space have a similar combination of environmental factors, and therefore are highly representative of each other.
Constituency: For any site in the network, its Constituency represent all locations that are best represented by the multivariate environmental drivers at that site.

Scientometric Portrait of Homi Jehangir Bhabha: The Father of Indian Nuclear Research Programme
No full textQuantitative and qualitative analysis with graphic representation of the publication productivity of a scientist facilitates easy and clear perception about the work of a scientist. Bhabha’s scientific work spanned over more than three decades (1933-1967) during which he published 104 publications, which could be classified into nine fields: Interaction of Radiation with Matter (4), Quantum Electrodynamics (5), Mathematical Physics (2), Cosmic Ray Physics (18), Elementary Particle Physics (14), Field Theory (15), General Physics (2), Nuclear Physics (4) and General (40). The highest number of publications (6) were published in 1941, 1945 and 1964 respectively. The average number of publications published per year was 3.05. His productivity coefficient was 0.05 which is a clear indicates that his publication productivity was quite consistent throughout his scientific career. He was single author in 79 of his publications and the main author in 24 publications indicates that he always preferred to work himself and lead the team as ‘mentor’. Bhabha had 22 collaborators during the period. Team of research collaborators working with a successful scientist documents the sociological aspect of history of science while generating knowledge by a leader in a domain.
Bhabha became a citable author in 1937. Bhabha received 1211 citations to his 30 publications out of 104 publications. Out of 104, 74 publications did not receive any citations. Out of 74 publications, 40 publications dealt subjects mainly of general interest. Bhabha’s 86.66 percent of cited publications received their first citations within four years of their publication indicates that his publications were noticed immediately and had direct impact among the fellow researchers working all over the world. His overall citation rate was 11.64 per cited publication. The highest citations 389 were received to the domain ‘Cosmic ray physics’. The highest number of citations received were 45 in 1938. His self-citations were only 24 (1.98%) and citations by others were 1187 (98.02%). The highest self citations were six in 1946. Bhabha’s mean diachronous self-citation rate was 1.98. The highest citation rate 28.4 was to the domain ‘Quantum electrodynamics. His single authored publications have received the highest number 863 (71.26%) of citations. Bhabha’s five publications have been cited more than 100 times each. His publications have been cited by the authors working in various diverse fields like nuclear physics, mathematical physics, instrumentation, optics, geophysics and geochemistry, condensed matter physics, applied physics, electrical and electronic engineering, mechanical engineering etc., indicating a very diverse influence and impact of Bhabha’s publications. Bhabha’s publications have also been cited by the Nobel laureates like V. L. Ginzberg, Wolfgang Pauli, H. A. Bethe, M. Born, W. Bothe, E. P. Wigner, H. Yukawa, P. M. S. Blackett and C. N. Yang which is an indication of his originality of ideas and high quality of publications

When freshly collected (Fig. 1), dorsal surfaces of carapace and chelipeds bright orange; tips of anterolateral teeth and cheliped carpal spine white; fingers of chelipeds mostly white except for orange base, distal third light brown; ambulatory legs with dorsal surfaces mostly orange except for white patches on propodus, ventral surfaces paler; prominent red band present that stretches from ventrum of posterolateral carapace margin to below frontal margin; rest of ventral surfaces pinkish-white. This colour pattern is unique amongst the species of Carcinoplax where colour in nature is known. Etymology. The name alludes to the prominent red band that spans the frontal and lateral parts of the carapace, which is diagnostic of the species. Remarks. It is unfortunate that no female specimens of the new species are available as one of the diagnostic characters for Carcinoplax H. Milne Edwards, 1852, s. str. is the large and expanded vulvae which do not have a cover or operculum (see Castro 2007: fig. 1). Carcinoplax fasciata n. sp. belongs to a group of species in which the carapace is distinctly more rectangular (rather than quadrate or subovate), with the dorsal carapace surface smooth, the external angle prominently developed into a distinct triangular tooth which does not reach the entire frontal margin, and the two anterolateral teeth are acute, slender and directed anteriorly with the tips hooked. The new species is perhaps most similar to C. specularis Rathbun, 1914 (= C. verdensis Rathbun, 1914; C. polita Guinot, 1989) from the Philippines, Japan, Indonesia, Vanuatu, Solomon Islands, New Caledonia, Fiji, Tonga and Maldives (Castro 2007: 642) but can be separated by several distinct characters. In C. fasciata n. sp., the anterolateral teeth are more acute and the tip of the first tooth is distinctly hooked (Figs. 1 A, 2A, 3B) (distinctly broader and more triangular in shape in C. specularis, cf. Fig. 5 A; Guinot 1989: pl. 8A, B); the gastric and branchial regions are more inflated, with the posterolateral margin distinctly more convex (Figs. 1 A, 2A) (branchial regions less inflated with the posterolateral margin slightly convex to almost straight in C. specularis, cf. Fig. 5 A, C; Guinot 1989: pl. 8A, B); the third maxilliped ischium is proportionately longer (Fig. 2 B) (relatively more quadrate in C. specularis, Fig. 5 B); the inner distal angle of the cheliped is armed with an acute spine (Figs. 1 A, 2A, 3C, D) (versus broader and more dentiform in C. specularis, Fig. 5 A); the chelae are less prominently inflated with the dorsal margin not distinctly crested and there is no window-like ovate structure present (Figs. 1 A, 2A, 3C, D, F) (chelae prominently inflated in adult males with the dorsal margin prominently crested in C. specularis, cf. Fig. 5 A; Guinot 1989: pl. 8A, C, D); pleonal somite 6 is distinctly broader (Fig. 2 C) (longitudinally more narrow in C. specularis, Fig. 5 D); the G1 is relatively more slender and longer with the distal part subtruncate (Fig. 4 A–D) (proportionately shorter, stouter with the distal part resembling a bird’s head in C. specularis, cf. Guinot 1989: fig. 34A); and the G2 distal segment is proportionately shorter (Fig. 4 E) (distinctly longer in C. specularis, cf. Guinot 1989: fig. 34B). The above differences are also valid for the two junior subjective synonyms of C. specularis (C. verdensis and C. polita), except for the presence of a window-like ovate structure on the dorsal part of the chela which is found only in C. specularis. Unpublished data by P. Castro, L. Corbari and the first author suggests C. specularis is a species complex; and the matter is now under study. Compared to the allied C. uncinata Castro, 2009, from New Caledonia, the anterolateral margin of C. fasciata n. sp. is relatively longer (Figs. 1 A, 2A) (relatively shorter, with the first anterolateral tooth closer to the external orbital angle in C. uncinata, cf. Castro 2009: fig. 1A); the anterolateral teeth are more acute and the tip of the first tooth is hooked (Figs. 1 A, 2A, 3B) (distinctly broader and more triangular in shape in C. uncinata, cf. Castro 2009: fig. 1A); male pleonal somite 6 is subrectangular in shape (trapezoidal in C. uncinata, cf. Castro 2009: fig. 1B); and the G1 is relatively more slender (Fig. 4 A–D) (proportionately stouter in C. uncinata, cf. Castro 2009: fig. 1C); and the G2 distal segment is proportionately shorter (Fig. 4 E) (distinctly longer in C. uncinata, cf. Castro 2009: fig. 1D). Carcinoplax fasciata n. sp. also resembles C. longipes (Wood-Mason, in Wood-Mason & Alcock, 1891) (see Huys et al. 2014, for authorship and dates) in its carapace form. The C. longipes as figured in Alcock & Anderson (1895: pl. 14 fig. 7) in the Investigator plates from the Andamans differs from that shown in Serène & Lohavanijaya (1973: 65 [part], pl. 14D), Guinot (1989: 303, pl. 10A–C) and Castro (2007: 636) from the Andamans and Philippines in having more triangular anterolateral teeth and distinctly shorter ambulatory legs (see Castro 2007: 637). It is possible that the type material is mixed and contains two species. From C. longipes s. str. (as defined by Guinot 1989; Castro 2007), C. fasciata n. sp. differs in having the tip of the first anterolateral tooth hooked (Figs. 1 A, 2A, 3B) (straight or almost so in C. longipes, cf. Guinot 1989: pl. 10A, B); the ambulatory legs are proportionately shorter, with the merus of P5 only reaching to the second anterolateral tooth (Figs. 1 A, 2A) (P5 merus reaching beyond the second anterolateral tooth in C. longipes, cf. Guinot 1989: pl. 10A); the fingers of the chela are shorter than the palm (Fig. 3 C, D, F) (fingers longer than the palm in C. longipes, cf. Guinot 1989: pl. 10C); the G1 is proportionately more slender and longer, with the distal part subtruncate (Fig. 4 A–D) (shorter and stouter with the distal part more dilated in C. longipes, cf. Guinot 1989: figs. 35A, 36A); and the G2 distal segment is distinctly shorter (Fig. 4 E) (proportionately longer in C. longipes, cf. Guinot 1989: figs. 35b, 36B). Castro (2007: 641) listed two ovigerous female specimens of C. specularis from the Maldives (The Natural History Museum, London, catalogue number 2007.64-65, station 143, 05º15.8’N 73º22.8’E- 05º13.7’N 73º23.6’E, 797 m) collected by the John Murray Expedition on 30 March 1934. This was the only record of this species from the Indian Ocean. These specimens appear to have been misplaced (P. Clark, pers. comm.), and we have not been able to locate them for this study. Considering their provenance, it is possible they also belong to C. fasciata n. sp.Published as part of Ng, Peter K.

Compared to <i>A. crosnieri</i>, the male chela of <i>A. ratnakara</i> <b>n. sp.</b> is relatively more elongated (Fig. 3 G) (relatively shorter in <i>A. crosnieri</i>, Manning 1993: fig. 4c); the female legs (notably the merus) are proportionately longer (Fig. 4 A–D) (shorter in <i>A. crosnieri</i>, Manning 1993: fig. 2d–g); there are no natatory setae on any of the male and female P2–P5 (Fig. 4) (distinct in at least P2 and P 3 in <i>A. crosnieri</i>, Manning 1993: figs. 2a, e, f, 3a); the surfaces of the male P2–P4 are covered with low pubescence (Fig. 4 E–H) (relatively glabrous in <i>A. crosnieri</i>, Manning 1993: fig. 4c–g); the telson of the male abdomen is more triangular in shape (Fig. 3 D) (more semicircular in <i>A. crosnieri</i>, Manning 1993: fig. 4h); and the female telson is more prominently recessed into somite 6 (Fig. 2 F) (less distinctly so in <i>A. crosnieri</i>, Manning 1993: fig. 3b).</p> <p> <i>Afropinnotheres guinotae</i> is known only from one male specimen. The male of <i>A. ratnakara</i> <b>n. sp.</b> differs from it in having the carapace more rounded in shape (Figs. 1 C, 3A) (proportionately wider in <i>A. guinotae</i>, Manning 1993: fig. 5a); the outer surface of the MXP3 only has scattered setae (Fig. 2 C) (conspicuously setose in <i>A. guinotae</i>, Manning 1993: fig. 5b); the meri of the P2–P5 are proportionately longer (Fig. 4 E–H) (relatively shorter in <i>A. guinotae</i>, Manning 1993: fig. 6b–e); there are no natatory setae on any of the male P2–P5 (Fig. 4 E–H) (at least on P2 and P 3 in <i>A. guinotae</i>, Manning 1993: fig. 6b–e); and the telson of the male abdomen is more acutely triangular with a rounded tip (Fig. 3 D) (broadly triangular with tip subtruncate in <i>A. guinotae</i>, Manning 1993: fig. 5d).</p> <p> <i>Afropinnotheres ratnakara</i> <b>n. sp.</b> can be distinguished from <i>A. larissae</i> by having the male carapace and pereiopods distinctly tomentose (Figs. 1 C, 4E–H) (dorsal surfaces almost glabrous or weakly tomentose and pereiopods in <i>A. larissae</i>, Manning 1993: figs. 7a, b, g–j, 8a, b, d–f); the male front is more entire, being barely sinuous (Fig. 3 A) (sinuous and clearly emarginate in <i>A. larissae</i>, Manning 1993: figs. 7a, 9a); the female front is slightly produced anteriorly, extending slightly beyond orbits (Figs. 1 A, B, 2A) (not protruding beyond orbits in <i>A. larissae</i>, Manning 1993: figs. 7a, 8a); the male and female chelae relatively more elongated (Figs. 2 D, 3G) (relatively shorter in <i>A. larissae</i>, Manning 1993: figs. 7f, 8d, e); the dactylus of P5 of the female is subequal in length to those in P2 and P3 (Fig. 4 D) (longest in <i>A. larissae</i>, Manning 1993: fig. 7j); and there are no natatory setae on the male P2–P5 (Fig. 4) (with long setae in <i>A. larissae</i>, Manning 1993: figs. 7a, b, 9a).</p> <p> <i>Afropinnotheres ratnakara</i> <b>n. sp.</b> can be distinguished from <i>A. monodi</i> by the female front been slightly produced anteriorly, extending slightly beyond the orbits (Figs. 1 A, B, 2A) (not protruding beyond orbits in <i>A. monodi</i>, Manning 1993: fig. 10a); the ambulatory meri are proportionately longer (Fig. 4) (shorter in <i>A. monodi</i>, Manning 1993: figs. 10d–g, 11d–h), and there are no natatory setae on the legs (with distinct setae at least on P2 and P 3 in <i>A. monodi</i>, Manning 1993 fig. 11f, g).</p> <p> Doflein (1904: 124, pl. 37 figs. 3, 4) reported an unidentified species of <i>Pinnotheres</i> from Algoa Bay, east of the Cape of Good Hope, South Africa (host unknown). The figure of the female specimen (Doflein 1904: pl. 37 figs. 3, 4) agrees well with <i>A. ratnakara</i> <b>n. sp.</b> in carapace shape and general features, including the proportions of the legs and abdomen. The MXP3 of his <i>Pinnotheres</i> sp. (Doflein 1904: text fig. 10), however, differs markedly from that of <i>A. ratanakara</i>, with the ischiomerus proportionately much longer and slender, the dactylus distinctly spatuliform and the exopod only about a third or half the length of the ischiomerus. The MXP3 of <i>A. ratanakara</i> actually agrees much better with that Doflein figured for his new species, <i>Pinnotheres villosissimus</i>, obtained from a holothurian near Padang, Sumatra. This species is currently placed in <i>Holotheres</i> (Ng & Manning 2003). The first author had a chance to examine the holotype female of <i>Pinnotheres villosissimus</i> in the Berlin Museum and its MXP3 structure is actually not the one figured by Doflein (1904: text fig. 11) as belonging to this species. It instead matches Doflein’s text figure 10, the one he cites as belonging to <i>Pinnotheres</i> sp. The first author has also examined many specimens of <i>P. villosissimus</i> from Papua New Guinea (see Van Den Spiegel & Jangoux 1989), and all their MXP3 are similar in form. It therefore appears that Doflein (1904) inadvertently transposed the figures of his <i>Pinnotheres villosissimus</i> and <i>Pinnotheres</i> sp., substituting one for the other. In such a case, the figure he provided for <i>Pinnotheres villosissimus</i> (Doflein 1904: text fig. 11) is actually that for his <i>Pinnotheres</i> sp. In fact, the descriptions of the MXP3 of these two species by Doflein actually agree better with the figures as elucidated here than what was printed originally. As such, Doflein’s (1904) <i>Pinnotheres</i> sp. may well be referable to what is described here as <i>Afropinnotheres ratnakara</i> <b>n. sp.</b></p> <p> Doflein’s (1904) mislabeling of the MXP3 structures has taxonomic consequences. Nobili (1905, 1906) in describing a new species, <i>Pinnotheres pilumnoides</i> from the Red Sea (on the basis of one female with no host data), noted that his species was close to <i>P. villosissimus</i> except that its MXP3 was very different to that figured by Doflein for this species. The MXP3 of <i>P. pilumnoides</i> (cf. Nobili 1906: fig. 12) superficially resembles that of <i>P. villosissimus</i> except that the ischiomerus appears to be stouter and the dactylus is shorter than the propodus. The first author has noticed that the proportions of the MXP3 dactylus of <i>P. villosissimus</i> vary considerably in his Papua New Guinea material (unpublished data) so Nobili’s (1905) of <i>P. pilumnoides</i> may be a junior synonym of <i>P. villosissimus</i>. Another species, <i>Pinnotheres dofleini</i> Lenz, in Lenz & Strunck, 1914, was described on the basis of one male specimen from Simon Bay (from an ascidian) in South Africa; with Lenz believing that this was the male of the <i>Pinnotheres</i> sp. described by Doflein (1904) from a female. He noted that the MXP3 of his male specimen was the same (Lenz & Strunck 1914: 282) as that figured by Doflein (1904: text fig. 10). In view of the present observation that Doflein confused his figures; Lenz in Lenz & Strunck’s (1914) specimen may well be the same as <i>P. villosissimus</i> s. str., although their hosts are different. In any case, the type specimens of <i>P. pilumnoides</i> Nobili, 1905, and <i>Pinnotheres dofleini</i> Lenz in Lenz & Strunck, 1914, need to be re-examined before any firm taxonomic decisions take place.</p> <p> Chopra (1931: 312, text figs. 3, 4, pl. 7 fig. 2) reported many specimens of <i>H. villosissimus</i> from the Andamans and noted that they agreed well with the description and figures of Doflein (1904), and figured the general habitus, chela, and male abdomen. They also agree with the material examined herein. Chopra nevertheless commented that the MXP3 of his specimens agree with that described by Doflein, although he did not figure it. His description of the carpus, propodus, and dactylus could be for either of Doflein’s taxa. Chopra did not indicate if he also denuded the ischiomerus to determine the shape and proportions. These specimens will need to be reexamined to be certain of their identity.</p> <p> Tirmizi & Ghani (1996: 89, fig. 34) described and figured an unidentified <i>Pinnotheres</i> species from a bivalve in Pakistan, which agrees in many respects with <i>Afropinnotheres ratnakara</i> <b>n. sp.</b> They may be conspecific.</p> <p> With regard to other pinnotherids, <i>Afropinnotheres ratnakara</i> <b>n. sp.</b> superficially resembles <i>Nepinnotheres margaritiferae</i> (Laurie, 1906), which has been reported as found in <i>Mytilus</i> sp. (= Indian <i>Perna</i>) (Mytilidae) and <i>Pinctada imbricata</i> Röding, 1798 [as <i>Margaritifera vulgaris</i> (Schumacher, 1817)] (Pteriidae) in Sri Lanka (Southwell 1911). The anterior part of the female carapace in <i>N. margaritiferae</i> is nevertheless more quadrate with the anterolateral margins more angular (more rounded in <i>A. ratnakara</i> <b>n. sp.</b>, Figs. 1 A, B; 2A), the MXP3 propodus is more elongated, with the dactylus short and inserted medially (propodus short and conical with long dactylus inserted sub-basally in <i>A. ratnakara</i> <b>n. sp.</b>, Figs. 2 C, 3B), and the ambulatory meri and dactyli are proportionately longer (relatively shorter in <i>A. ratnakara</i> <b>n. sp.</b>, Figs. 1, 4) (cf. Laurie 1906: text figs. 10, 10a; Southwell 1911: pl. 3 figs. 3, 3a).</p> <p> <i>Afropinnotheres ratnakara</i> <b>n. sp.</b> resembles <i>Pinnotheres mactricola</i> in the carapace shape, but the merus of the P5 of <i>P. mactricola</i> is proportionately shorter (Alcock & McArdle 1903: pl. 62 figs. 4, 5) (longer in <i>A. ratnakara</i> <b>n. sp.</b>, Figs. 1, 2 A, 4) and the propodus of MXP3 is proportionately longer and the dactylus only reaches to the tip of the propodus (Alcock & McArdle 1903: pl. 62 fig. 5b) (propodus short and conical with the dactylus extending beyond the tip of the dactylus in <i>A. ratnakara</i> <b>n. sp.</b>, Figs. 2 C, 3B).</p>Published as part of <i>Ng, Peter K.

It is the name of the home institute of the first author, PTA. The gender is feminine.</p> <p> <i>Diagnosis</i></p> <p> <i>Adult female.</i> Body (5–6 mm Tolal Length (TL), without egg sacs, from anterior margin of head to distal end of rami) elongate, cyclopiform; pedigerous somites with 4 pairs of elongated ventrolateral processes. Antennule 6-segmented, all segments with marginal setae. Antenna 2-segmented, basal segment armed with 1 accessory process; distal segment modified into terminally bent hook. Mandible, represented by blade, apically curved with many marginal spinules. Maxilla 2-segmented, first segment unarmed; terminal segment with 1 robust ventral seta at middle, apex armed with bunch of spinules. Maxilliped reduced. First four pairs of legs are biramous, with 3-segmented rami. Leg 5 uniramous, indistinctly 2-segmented or fused to form long lobe. Leg 6 absent. Genital double somite with genital opening on ventral surface. Egg sac multiseriate.</p> <p> <i>Adult male.</i> Smaller than female (0. 45 times as long as female). Body (2.4–2.6 mm TL) cyclopiform, with distinct segmentation, attached to female by maxilliped. Pedigerous somites without ventrolateral processes. Genital double segment with usual posteroventral ridges. Abdomen with 4 somites. Legs and caudal ramus as in female. Terminal long papilla of the caudal ramus with 2 small trifurcating papillae.</p> <p> <i>Remarks</i></p> <p> The structure of the general cyclopoid body, mouthparts, and other appendages identifies the new species, <i>Hirodai ohtsukai</i>, as a member of Cyclopoida and Ergasilida. The genus <i>Hirodai</i> gen. n. can be well separated from all other known cyclopoid families by the following two characteristics: (1) 2-segmented maxilla, where the first segment is unarmed; the terminal segment has a ventral robust seta at the middle, the rounded apex is armed with a bunch of spinules on both surfaces, except in the inner middle portion; (2) maxilliped is vestigial in female and 3-segmented in male. <i>Hirodai</i> gen. n. possesses the following combination of characteristics: (1) pedigerous somites with 4 pairs of elongated ventrolateral processes; (2) genital double somite is 0.7 times as wide as 5 th segment; 2.1 times as wide as long; genital opening ventrally; (3) egg sac multiseriate; (4) maxilliped unsegmented and reduced in the adult female; (5) caudal ramus with 2 long and 2 small terminal papillae; (7) legs 1 to 4 biramous with 3-segmented rami armed with setae, fifth leg uniramous and unsegmented, leg 6 absent. To the best of our knowledge, of the 69 families of Ergasilida (Uyeno 2022; Walter and Boxshall 2023), none displays either of the two key characters (2-segmented maxilla, the terminal segment with a ventral robust seta at the middle, the rounded apex is armed with a bunch of spinules on both surfaces, except in the inner middle portion (3-segmented and only the outer margin is denticulated in remaining Cyclopoida); maxilliped is vestigial in female and three segmented in male (all other copepods of Cyclopoida possess 3-segmented maxilliped in both sexes except the family Ergasilidae which is completely absent in female). These unique characters (structure of maxilla and maxilliped) along with the combination of morphological characters makes it difficult to place the new genus in any one of the existing cyclopoid families, and hence we propose to establish the family Uranoscopicolaidae fam. n. for the new genus and species.</p>Published as part of <i>Aneesh, Panakkool Thamban, Helna, Ameri Kottarathil, Kumar, Appukuttannair Biju & Venmathi Maran, Balu Alagar, 2023, Proposal of a new family for Hirodai ohtsukai gen. n. et sp. n.

Dynamics of Network Formation Processes in the Co-Author Model
No full textThis article studies the dynamics in the formation processes of a mutual consent network in game theory setting: the Co-Author Model. In this article, a limited observation is applied and analytical results are derived. Then, 2 parameters are varied: the number of individuals in the network and the initial probability of the links in the network in its initial state. A simulation result shows a finding that is consistent with an analytical result for a state of equilibrium while it also shows different possible equilibria.Dynamics, Network, Game Theory, Model,Simulation, Equilibrium, Complexity
