We document for the first time the diversity of vascular plants of Chandra Tal and Suraj Tal, two high-altitude wetlands (HAWs) spanning the cold desert region of Lahaul-Spiti, showing the occurrence of 188 species and one variety distributed among 97 genera and 29 families. Only one species, Ephedra intermedia Schrenk & C.A. Mey. is a gymnosperm, and the other 187 species are angiosperms. Of the angiosperms, Asteraceae is the dominant family, consisting of 27 species and one variety in 17 genera. Among the species, six are classified as threatened, 17 species are native, and two species (Eritrichium nanum (L.) Gaudin and Ranunculus trivedii Aswal & Mehrotra) are endemic to the Himalayan region. We provide baseline data for future research on the floristic diversity of two major HAWs of Lahaul-Spiti. We also highlight the importance of HAWs for the conservation of species.

Reproductive Tract Infection

Background: Reproductive tract infection (RTI) is a serious public health problem particularly among the women in reproductive age group. Tribal women particularly living in high altitude cold areas are more vulnerable to these infections as availability of water for domestic purpose is scarce hence affects personal hygiene.Methods: A door to door survey was conducted by canvassing a pre-designed interview schedule for capturing the reported symptoms of RTI among 494 women in the age group 15-49 years in Lahaul and Spiti district of Himachal Pradesh.Results: Around 26% of the respondents reported one or the other symptoms of RTI experienced by them during three months preceding the survey. The reported symptoms were mostly related to discharge.Conclusions: The study is carried out among women of high-altitude tribal areas of Lahaul and Spiti district of Himachal Pradesh, where such data/information is not available. Maintenance of personal hygiene is poor, more than one-fourth women had one or the other symptoms of RTI. Lower economic status and personal hygiene practices are strongly associated with RTI. The findings of the study will draw attention of Scientists, Program managers to address the issues for qualitative improvement of female population of the area. Need to sensitise the masses on the issues of RTI and strengthen its outreach health services in the district.

Chilling Treatment

Henbane (Hyoscyamus niger L.), an economically important medicinal plant, has an endangered status in Himachal Pradesh (India) that needs appropriate conservation interventions. We have examined seed physiological aspects of H. niger from Lahaul (Himachal Pradesh, India), a cold desert region. The freshly harvested seeds exhibited complete dormancy. Gibberellic acid (GA3) and chilling treatment strongly promoted seed germination which was accompanied by increased α-amylase activity. KNO3, NaN3 and sodium nitroprusside (SNP), an NO donor, also promoted germination. During storage, the seeds retained high viability even after a storage of 72 months under ambient conditions. However, they remained dormant during the entire storage period. The responsiveness of seeds to GA3 and chilling treatment gradually declined with progression of storage period. Concomitantly, the triphenyl tetrazolium chloride (TTC) reduction ability of seeds was lowered. The seed responsiveness to KNO3, NaN3 and SNP during storage increased until one year and decreased thereafter. With the progression of the storage period, seeds exhibited elevated lipid peroxidation and reduced catalase activity implying a role of oxidative stress in observed changes. The involvement of phenolics in seed dormancy of H. niger was not evident. The findings are of significance for conservation and cultivation of H. niger through seeds in the arid mountain region.

Pectiniunguis aequatorialis sp. nov. (Chilopoda: Geophilomorpha: Schendylidae) is described and illustrated on the basis of specimens collected in the Cayambe-Coca Ecological Reserve in the High Andes of Ecuador. The new species is characterized by having ventral pore-fields on the anterior region of the trunk only, a trait that is shared by a single Neotropical congener: Pectiniunguis ascendens Pereira, Minelli & Barbieri, 1994 to which it is similar and is compared taxonomically. This is only the second report of a species of the genus Pectiniunguis Bollman, 1889 from mainland Ecuador. The other taxon is Pectiniunguis roigi Pereira, Foddai & Minelli, 2001, so far only known from the type locality, Limoncocha (Sucumbíos Province), and herein reported for the first time from Parque Nacional Sumaco Napo-Galeras (Napo Province).

The family Orthalicidae is wide-spread in the Neotropics and a major member of the land snail fauna of most South American countries. This checklist presents the species known to exist in Ecuador. It is based on data from relevant literature and museums world wide. There are 168 species in total, 63 of which occur on the Galápagos; 9 species are listed for the first time from this country. New synonymies are: Bulimus abscissus Pfeiffer, 1855 = Drymaeus (D.) fallax Pfe-iffer, 1853; Bulimus caliginosus Reeve, 1849 = Bulimus irregularis Pfeiffer, 1848 = Naesiotus quitensis (Pfeiffer, 1848). In the geographical analysis only the mainland species have been taken into account. The species were sampled at 128 mainland localities, 46 of which have been sampled after 1950, indicating that some parts of the country are undersampled. The potential distribution has been analysed at (sub-)generic level, using Maxent and GIS software. Finally four directions for future research are suggested: strengthening the locality database, improved sampling for better modelling, analysis of models on a greater spatial scale and phylogeographic analyses.

Annotated Checklist

The ephemeral and fragmented nature of plant communities in the desert region of Ica, Peru have contributed to the poor documentation of its flora. This study provides the first comprehensive checklist and analysis of the vascular plants and habitats of the region, based on over 1800 herbarium collections, site-specific vegetation surveys and monitoring (2001–2017). Here, we report 501 taxa belonging to 283 genera in 68 families, with an outstanding number of taxa (297) representing new records for the region; over 10% of the flora (52 taxa) is categorised as threatened (CR, EN, VU). Asteraceae is the largest family in the checklist, followed by Poaceae, Fabaceae and Solanaceae. The highest species richness is found in quebradas and huaycos (170 taxa), followed by lomas (137 taxa) and huertas (115). Of the lomas taxa, 28% are assessed nationally as threatened, and 95 taxa (68%) are endemic to Peru. Across all habitats five species are restricted to the Ica region (Cleistocactus clavispinus, Haageocereus icensis, Onoseris humboldtiana, Nolana willeana, Tecoma fulva subsp. guarume). Nolana willeana, not collected since 1956, was rediscovered in 2006. We provide insights into habitat and taxonomic delimitation of enigmatic species in the following genera: Bulnesia, Capparis, Eremocharis, Hoffmannseggia, Leptoglossis, Lomanthus Maytenus, Poissonia and Weberbauerella, among others. We support the reinstatement of Prosopis limensis as a valid species and provide information for its identification in the field. Analysis of Inga feuillei as an ancient domestication vital to agriculture, is provided, and we report an additional 127 cultivated species associated with traditional agriculture, assessing origins and conservation priority. We present climatic and geological observations for the region with spatial and ENSO-related research from data, plots and transects. A vegetation map and niche model are provided. Threatened lomas species are detailed to support conservation and policy. To aid identification we provide photographs of 155 plant species and all key habitats. The sustainable wellbeing of the Ica region depends on concerted collaboration to monitor, conserve and restore native plants wisely for the natural resources they provide to people and agriculture.

At Mount Albert, Quebec, many taxa are found exclusively on either serpentine or amphibolite contiguous formations. This exclusivity is clearly more noticeable within the saxicolous lichens than within the other groups. Serpentine seems to be an unfavourable substratum for the growth of saxicolous lichens. There are more infrequent taxa on serpentine than on amphibolite. The saxicolous, muscicolous, and terricolous lichen flora and the lichenicolous fungi of the plateau include 202 taxa, most of which have an arctic affinity. Of these taxa, 36 are recorded for the first time in Quebec, 16 in Canada and, 11 in North America. The ecological influence of serpentine on the lichens is, in many aspects, similar to that observed on vascular plants.
