  1. 16. Plants as Sources of Natural and Effective Acaricides : Against Ixodes ricinus  (Acari: Ixodidae)

    Författare :Fawzeia Elmhalli; Giulio Grandi; Richard Wall; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acaricidal; Ixodes ricinus; Libyan plants; essential oils; Plant-derived acaricides.; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Ticks and tick-borne diseases are major health hazards worldwide, with increasing numbers of cases of Lyme disease and tick-borne encephalitis reported yearly. Meanwhile, concerns about the environmental impact and safety of chemical acaricides are driving research into alternative control methods, such as plant-based acaricides. LÄS MER

  3. 17. Exceptionally Preserved Cambrian Lophotrochozoa : Taxonomy, Systematics and Taphonomy of Chengjiang and Indian Springs Lophophorates

    Författare :Aodhán D. Butler; Michael Streng; Lars E. Holmer; Christian Skovsted; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Brachiopoda; Chengjiang; Lagerstätte; Cambrian Explosion; palaeobiology; stem-group; entoproct; phoronid; tommotiid; exceptional preservation.; Earth Science with specialization in Historical Geology and Palaeontology; Geovetenskap med inriktning mot historisk geologi och paleontologi;

    Sammanfattning : The origin and evolution of Lophotrochozoa can be traced to the plethora of lower Cambrian scleritome taxa.  We aim to determine the character suites linking these stem-Lophotrochozoa to their extant crown relatives, in particular the small shelly tommotiids and the stem-group brachiopods.

  4. 18. Polyporoid fungi of Tanzania : Taxonomy, transcriptomics and biochemical analyses of Kusaghiporia usambarensis and Piptoporellus baudonii

    Författare :Juma Mahmud Hussein; Sanja Tibell Savić; Donatha Tibuhwa; Christina Wedén; Ulf Göransson; Jan Stenlid; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematics; Laetiporaceae; pharmacognosy; cysteine-rich peptide; baudonii; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Polyporoid fungi refers to basidiomycetes with fruiting bodies with the hymenium located to the inner surfaces of pores or narrow tubes. The majority of polyporoids belongs to Polyporales. Most Polyporales are saprobes, but some are plant pathogens. LÄS MER

  5. 19. Lichens in Mountain Rainforests of Tanzania : Studies of Usnea and Calicioids

    Författare :Stella Gilbert Temu; Sanja Tibell Savić; Leif Tibell; Philippe Clerc; Göran Thor; Donatha Tibuhwa; Einar Timdal; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lichens; Usnea; calicioids; molecular phylogeny; secondary chemistry; morphotypes; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Sammanfattning : Lichens occur in various habitats. They often have narrow niches and are sensitive to environmental changes leading to their use as bioindicators of environmental disturbances and conditions; air and heavy metal pollution, agricultural toxins, assessing forest continuity and drought tolerance.

  7. 20. Snake Gourds, Parasites and Mother Roasting : Medicinal plants, plant repellents, and Trichosanthes (Cucurbitaceae) in Lao PDR

    Författare :Hugo J. de Boer; Lars Björk; Mats Thulin; Thomas Jaenson; Victoria Reyes-Garcia; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Trichosanthes; Ethnobotany; Similarity of Knowledge; Biogeography; Molecular Dating; Brou; Saek; Kry; Mother roasting; Postpartum healthcare; Parturition; Childbirth; Traditional Medicine; Plant repellents; Fermented fish; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Sammanfattning : Background. Traditional plant use was studied in Lao PDR. Research focused on medicinal plant use by the Brou, Saek and Kry ethnic groups, traditional plant repellents against parasitic arthropods and leeches, and the phylogeny and biogeography of the medicinally-important snake gourd genus (Trichosanthes, Cucurbitaceae).  Methods.
