  1. Effects of chemicals from longline baits on the biting behaviour of loggerhead sea turtles

    Effects of chemicals from longline baits on the biting behaviour of loggerhead sea turtles

    Item type: Journal Article • Journal: African Journal of Marine Science
    The biting behaviour of the loggerhead sea turtle Caretta caretta, a high bycatch species by longline fishing gear, was studied on 30 wild specimens held temporarily at rescue centres. To account for repeated measures, the data were analysed using mixed-effects...
  2. Establishment of a <em>Nothofagus alessandrii</em> plantation using different levels of shade and weed control methods in Talca province, central Chile

    Establishment of a <em>Nothofagus alessandrii</em> plantation using different levels of shade and weed control methods in Talca province, central Chile

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    There is a lack of information regarding the establishment of Nothofagus alessandrii plantations, including any impacts that shading and weed control may have on early survival and growth. A trial was therefore initiated where four shade levels (0% and RachelĀ®...
  3. Congregations of wintering Egyptian Vultures <em>Neophron percnopterus</em> in Afar, Ethiopia: present status and implications for conservation

    Congregations of wintering Egyptian Vultures <em>Neophron percnopterus</em> in Afar, Ethiopia: present status and implications for conservation

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    The Endangered Egyptian Vulture Neophron percnopterus congregates in communal roosts in the wintering areas and where food availability is high, where even a single threat might lead to substantial population declines. Thus, more research on the congregation sites is needed...
  4. Reef fishes recruited at midwater coral nurseries consume biofouling and reduce cleaning time in Seychelles, Indian Ocean

    Reef fishes recruited at midwater coral nurseries consume biofouling and reduce cleaning time in Seychelles, Indian Ocean

    Item type: Journal Article • Journal: African Journal of Marine Science
    In coral reef restoration, coral gardening involves rearing coral fragments in underwater nurseries prior to transplantation. These nurseries become fish-aggregating devices and attract biofouling. We hypothesised that: (1) the presence of corals at a nursery is critical to recruit fish...
  5. Alarming decline and range reduction of the highly threatened Great Bustard <em>Otis tarda</em> in Morocco

    Alarming decline and range reduction of the highly threatened Great Bustard <em>Otis tarda</em> in Morocco

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    A Great Bustard Otis tarda survey carried out in spring 2015 in Morocco confirmed the decline of this highly endangered population. Bustards were only seen at two of the seven leks occupied ten years ago. The total number of birds...
  6. The influence of food abundance, food dispersion and habitat structure on territory selection and size of an Afrotropical terrestrial insectivore

    The influence of food abundance, food dispersion and habitat structure on territory selection and size of an Afrotropical terrestrial insectivore

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Most tropical insectivorous birds, unlike their temperate counterparts, hold and defend a feeding and breeding territory year-around. However, our understanding of ecological factors influencing territory selection and size in tropical insectivores is limited. Here we examine three prominent hypotheses relating...
  7. The relative importance of climatic gradient versus human disturbance in determining population structure of <em>Afzelia africana</em> in the Republic of Benin<xref ref-type="fn" rid="F0000"/>

    The relative importance of climatic gradient versus human disturbance in determining population structure of <em>Afzelia africana</em> in the Republic of Benin<xref ref-type="fn" rid="F0000"/>

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The study aimed to investigate the relative significance of effects of climatic variability and human disturbance on the population structure of the threatened species Afzelia africana Sm. ex Pers. in the Republic of Benin in West Africa. Forest inventory data...
  8. Nest boxes for Cape Parrots <em>Poicephalus robustus</em> in the Hogsback area, Eastern Cape, South Africa

    Nest boxes for Cape Parrots <em>Poicephalus robustus</em> in the Hogsback area, Eastern Cape, South Africa

    Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology
    Breeding propensity of tree-cavity nesting bird species are often limited by a shortage of natural nesting sites. Artificial nests can be used to provide alternative nest sites. Cape Parrots Poicephalus robustus are nationally endangered and nest in existing tree-cavities in...
  9. A decision support tool approach based on the Electre TRI-B method for the valorisation of tropical timbers from the Congo Basin: an application for glulam products

    A decision support tool approach based on the Electre TRI-B method for the valorisation of tropical timbers from the Congo Basin: an application for glulam products

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    An alternative approach to the formal management strategy of tropical timber species from the Congo Basin was investigated. It focused on the development of glulam, with an aim to specify a decision support model for the valorisation of tropical timber...
