Ecology and phytosociology. – On Majorca, Orobanche rumseiana grows on a karstic, slightly sloped, rocky plateau close to the coast with a moderate influence of sea spray. It can be found in Smilaco balearicae-Ampelodesmetum mauritanicae Rivas-Martínez 1992 (alliance Oleo-Ceratonion siliquae Guinochet & Drouineau 1944; order Pistacio lentisci- Rhamnetalia alaterni Rivas-Martínez 1975; class Quercetalia Ilicis Molinier 1934) (sensu RIVAS- MARTÍNEZ & al., 2001), a Mediterranean shrubby vegetation that grows in sunny, poor soils. InMinorca, the species ismorewidelydistributed (Fig. 3) and although it can onlybe found near tothe coast,it has also been observed mainly in two plant communities: in Loto tetraphylli-Ericetum multiflorae O. Bolòs & Moliner 1958 (alliance Rosmarinion officinalis Molinier 1934; order Rosmarinetalia officinalis Molinier 1934; class Rosmarinetea officinalis Rivas-Martínez & al. 1991) (sensu RIVAS- MARTÍNEZ & al., 2001) in limestone soils mostly originating from Quaternaryfossil dunes; and in Ampelodesmo mauritanicae- Ericetum scopariae O. Bolòs & al. 1970 (alliance Ericenion arboreae Rivas-Martínez & al.1986; order Pistacio lentisci- Rhamnetalia alaterni Rivas-Martínez 1975; class Quercetalia Ilicis Molinier 1934) (sensu RIVAS- MARTÍNEZ & al., 2001) in siliceous sandy soils. Both plantassociations are linked to vegetation in relatively low shrub-lands and open spaces. In all cases, it parasitizes on Rosmarinus officinalis. Distribution, bioclimatology and biogeography. – Orobanche rumseiana is only known to grow in the Eastern Balearic Islands. It should be currently regarded as a stenochorous endemism of the coastal ecosystems where it grows in a reduced and discontinuous area, on Majorca in the north, in Serra de Tramuntana, near Cala Sant Vicenç, Pollença, but it was also reported by F. Rumsey in Alcudia; and in Minorca it is always found near to the coast (normally less than 500 m from the sea) but is more widely distributed in the north and south of the island, with at least six recorded populations (Fig. 3). On this island, all attempts to locate this species in apparently favourable inland habitats have failed. It grows in Mediterranean pluviseasonal-oceanic bioclimates, in territories inthe Thermo-Mediterranean stage. From abiogeographicstandpoint,it isincluded inthe Balearic-Catalan- Provençal Province, Balearic Subprovince, Minorcan and Majorcan Sectors (sensu RIVAS- MARTÍNEZ & al., 2002), with a typically Mediterranean maritime climate characterised by mild and rather rainy winters and veryhot and dry summers. The drought period normally lasts six or more months. It grows from 2 to 105 m above sea level. The flowering period is quite long, lasting from Aprilto early June. Etymology. – The epithet “ rumseiana ” named after Fred Rumsey (BM) who showed the authorsthe place on Majorca where the new species grows. Conservation status and proposals. – In the last ten years, the known population of O. rumseiana on Majorca has undergone important variations in plant number. Census figures vary, with as many as 30 individuals having been recorded in the most favourable years, compared with no plants or only a few isolated individuals in other years. Even if other populations exist, e.g. in Alcudia, as indicated by Rumsey, it is highly likely that these would also display similar variations in plant number from one yearto another. Populations on Minorca seemto be more constant in terms of plant number, at least in the last five years. It is likely that some populations on both islands have been destroyed by urban development, particularly in coastal areas. Moreover, a large population of feral goats has been detected on Majorca in the area of Coves Blanques, exerting strong herbivorous pressure on vegetation. It seems that goats look for Orobanche due to its juicy stem and grazed plants have been observed in this area. For thisreason, and due tothe increasing pressureof negative human activities inrecent decades, we propose that this new species be classified as Vulnerable (VU) according to IUCN (2001) criteria. Although all the known populations are found in areas with some type of legal protection against urban development, at regional level as is the case of the Natural Areas of Special Interest (ANEI) in the Balearic Islands, or even at European level as Sites of CommunityInterest (SCI) withinthe Natura 2000 Network, none of these legal instruments provides integral protection against threatssuch as invasive species or changes in land use. For these reasons, urgent conservation measures should be implemented to protect the populations and natural habitats of O. rumseiana . Iconography. – BECKETT (1993: tab. 61, 4, sub Orobanche rosmarina). Taxonomy. – Within the subgen. Trionychon, O. rumseiana presents a number of features, described in the diagnosis, that are not normally found in any other taxon in this group. Although it has certain similarities with O. rosmarina, O. mariana and O. pseudorosmarina (see Appendix 1 for the studied specimens), important morphological differences between these taxa warrant its recognition at species level (Table 1). Thus, it can be discriminated from these allied taxa mainly by the obtuse corolla lobes with a mucro up to 0.7 mm long and also by the stamen filaments, which are hairy in the lower half, with hairs up to 0.4 mmlong. Furthermore, certain characteristics distinguish it from O. rosmarina: its thinner stem, 2-4.5 mm diameter at medium height; denselyglandular pubescent rachis(hairs 0.2-0.6 mm long); bracts with longer glandular hairs (≤ 0.5 mm); lanceolate linear bracteoles, usually narrower (0.7-1.5 mm); calyx teeth more acuminate and with denser glandular indumentum; glandular ciliate corolla margins (hairs ≤ 0.4 mm). The differences with O. mariana are as follows: wider inflorescence (2.3-3 cm) with a more rounded and obtuse apex, rarely subobtuse; uniform and densely glandular pubescent calyx in the upper half; glandular ciliate corolla margins (hairs ≤ 0.4 mm); anthers usually shorter (1.1-1.3 mm) and ciliate at the base with a few long hairs (≤ 0.6 mm), sometimes deciduous. The differences with O. pseudorosmarina are as follows: a taller habit (≤ 26(-35) cm); rachis with longer glandular hairs (≤ 0.6 mm); longer bracts [(6) 7-12 mm]; bracteoles usually wider (0.7-1.5 mm); longer corolla (≤ 18 mm); anthers usually longer(1.1-1.3 mm); ovary and style glabrous. In addition to the morphological differences, these group species also display a distinct geographic distribution pattern. Thus, O. rumseiana is restricted to the eastern Balearic Islands, O. rosmarina is distributed in the southwest of continental Europe, O. mariana has onlybeen reported inSierraMorena (southwest of the Iberian Peninsula), and O. pseudorosmarina is distributed throughout coastal areas of the Eastern Mediterranean region.

Dispelling the Myths Behind First-author Citation Counts
We 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

SRide, a server for identifying stabilizing residues in proteins
Residues expected to play key roles in the stabiliza-tion of proteins [stabilizing residues (SRs)] are selec-ted by combining several methods based mainly on the interactions of a given residue with its spatial, rather than its sequential neighborhood and by con-sidering the evolutionary conservation of the resi-dues. A residue is selected as a stabilizing residue if it has high surrounding hydrophobicity, high long-range order, high conservation score and if it belongs to a stabilization center. The definition of all these parameters and the thresholds used to identify the SRs are discussed in detail. The algorithm for identi-fying SRs was originally developed for TIM-barrel proteins [M. M. Gromiha, G. Pujadas, C. Magyar, S. Selvaraj, and I. Simon (2004), Proteins, 55, 316– 329] and is now generalized for all proteins of known 3D structure. SRs could be applied in protein engineering and homology modeling and could also help to explain certain folds with significant stability. The SRide server is located a
