  • Wege, Mia; Oosthuizen, W.C. (Wessel Christiaan); Reisinger, Ryan Rudolf; Bester, Marthan Nieuwoudt; De Bruyn, P.J. Nico; Etienne, Marie-Pierre (Wiley, 2016-07)
    Recent pup population estimates of sympatric Subantarctic (Arctocephalus tropicalis) and Antarctic fur seals (A. gazella) at Marion Island are presented. Published pup population estimates of A. tropicalis (1995 and 2004) ...
  • Dietemann, Vincent; Eyer, Michael; Neumann, Peter (Public Library of Science, 2016-08-25)
    Honey bees, Apis species, obtain carbohydrates from nectar and honeydew. These resources are ripened into honey in wax cells that are capped for long-term storage. These stores are used to overcome dearth periods when ...
  • Moritz, Robin F.A.; Kurze, Christoph; Routtu, Jarkko (Elsevier, 2016-03)
    Organisms living in large groups, such as social insects, are particularly vulnerable to parasite transmission. However, they have evolved diverse defence mechanisms which are not only restricted to the individual’s ...
  • Thomas, H.G. (Hannah Grace); Bateman, Philip W.; Scantlebury, Michael; Bennet, Nigel C, 1961-; Hayssen, V. (Wiley, 2012-11)
    Little is known about how environmental factors such as season influence burrowing activity, burrow structure or reproductive behaviour in subterranean mammals. We excavated burrow systems of male and female Georychus ...
  • Bennett, Nigel C.; Omerba si c, Damir; Smith, Ewan St. J.; Moroni, Mirko; Homfeld, Johanna; Eigenbrod, Ole; Reznick, Jane; Faulkes, Chris G.; Selbach, Matthias; Lewin, Gary R. (Elsevier, 2016-10-11)
    The naked mole-rat is a subterranean rodent lacking several pain behaviors found in humans, rats, and mice. For example, nerve growth factor (NGF), an important mediator of pain sensitization, fails to produce thermal ...
  • Lindsey, Peter Andrew; Ripple, William J.; Abernethy, Katharine; Betts, Matthew G.; Chapron, Guillaume; Dirzo, Rodolfo; Galetti, Mauro; Levi, Taal; Macdonald, David W.; Machovina, Brian; Newsome, Thomas M.; Peres, Carlos A.; Wallach, Arian D.; Wolf, Christopher; Young, Hillary (Royal Society, 2016)
    Terrestrial mammals are experiencing a massive collapse in their population sizes and geographical ranges around the world, but many of the drivers, patterns and consequences of this decline remain poorly understood. ...
  • Fitza, Katrin N.E.; Garnas, Jeffrey R.; Slippers, Bernard; Tabata, Masanobu; Kanzaki, Natsumi; Kimura, Koki (Elsevier, 2016-12)
    The mutualism between siricid woodwasps and Amylostereum fungal symbionts has long been considered to be species-specific. Recent studies from North America have challenged this assumption, where native siricids and the ...
  • Jamison, Samantha-Leigh; Robertson, Mark P.; Engelbrecht, I.A. (Ian); Hawkes, Peter (AOSIS Open Journals, 2016-09-29)
    Many studies that evaluate rehabilitation make use of invertebrate bioindicators. Invertebrates, especially ants, make useful indicators as they are sensitive to environmental change. We compared ant assemblages in ...
  • Lindsey, Peter Andrew; Nyirenda, Vincent R.; Chewe, Felistus C.; Chisha-Kasumu, Exildah (AOSIS Open Journals, 2016-07-26)
    Deforestation and habitat fragmentation have long been known as drivers of wildlife depletion but information on their specific impacts on cavity-nesting birds in the miombo woodlands has been lacking. A comparative study ...
  • Bennett, Nigel C.; Santema, Peter; Teitel, Zachary; Manser, Marta; Clutton- Brock, Tim (Oxford University Press, 2013)
    Although the ultimate causes for variation in contributions to helping in cooperative breeders are increasingly well understood, the underlying physiological mechanisms remain largely unknown. Recent work has suggested ...
  • Yetman, Caroline Angela; Scott, Elizabeth; Visser, John D.; Olivier, Lauren; Broadley, Donald G. (Magnolia Press (open access), 2013)
    Pyxicephalus currently contains three recognized species, viz. P. adspersus, P. edulis and P. obbianus, the former two of which have a long history of confusion. Parry (1982) described P. adspersus angusticeps from Beira, ...
  • Strumpher, Werner P.; Villet, Martin H.; Sole, Catherine L.; Scholtz, Clarke H. (Brill Academic Publishers, 2016-01)
    Extant genera and subgenera of the Trogidae (Coleoptera: Scarabaeoidea) are reviewed. Contemporary classifications of this family have been based exclusively on morphological characters. The first molecular phylogeny for ...
  • Dietemann, Vincent; Neumann, Peter; Lin, Zheguang; Page, Paul; Li, Li; Qin, Yao; Zhang, Yingying; Hu, Fuliang; Zheng, Huoqing (Public Library of Science, 2016-09-08)
    The poor health status of the Western honey bee, Apis mellifera, compared to its Eastern counterpart, Apis cerana, is remarkable. This has been attributed to lower pathogen prevalence in A. cerana colonies and to their ...
  • Millar, Robert P.; Newton, Claire L. (Nature Publishing Group, 2013-08)
    Reproductive hormones affect all stages of life from gamete production, fertilization, fetal development and parturition, neonatal development and puberty through to adulthood and senescence. The reproductive hormone cascade ...
  • Mendonça, Rute; Gaynor, D.; Clutton-Brock, Tim H.; Zöttl, Markus; Vullioud, Philippe; Ticó, Miquel Torrents; Mitchell, Adam (National Academy of Sciences, 2016-09)
    In many cooperative breeders, the contributions of helpers to cooperative activities change with age, resulting in age-related polyethisms. In contrast, some studies of social mole rats (including naked mole rats, ...
  • Rolo, Victor; Rivest, David; Lorente, Miren; Kattge, Jens; Moreno, Gerardo (Wiley, 2016-10)
    1. Agricultural intensification is one of the main causes of biodiversity loss world-wide. The inclusion of semi-natural features in agricultural landscapes is suggested as a means of enhancing farm biodiversity, but ...
  • Crewe, Robin M. (AOSIS Open Journals, 2016-09)
    Scholarly academies have been in existence for about 350 years, with the oldest being those that were established in Europe in the 17th century. These institutions consist of groups of individuals who are elected by their ...
  • Bush, Samantha J.; Slippers, Bernard; Neser, S. (Stefanus); Harney, Marlene; Dittrich-Schroder, Gudrun; Hurley, Brett Phillip (Entomological Society of Southern Africa, 2016-09)
    The increased movement of goods and pathways to transport these goods around the world, combined with the global homogenisation of cultivated areas has resulted in an increase in insect movement and establishment ...
  • Scholtz, Clarke H. (Entomological Society of Southern Africa, 2016-09)
    A number of changes have taken place in the higher classification of southern African insects since the last time it was documented in full (Scholtz & Holm 1985) and there is currently no comprehensive modern classification ...
  • Moritz, Robin F.A.; Jarosch, Antje (Springer, 2012-09)
    RNA interference involves the targeted knockdown of mRNA triggered by complementary dsRNA molecules applied to an experimental organism. Although this technique has been successfully used in honeybees (Apis mellifera), ...
