    • Dramatic niche shifts and morphological change in two insular bird species 

      Alström, Per (2015)
      Colonizations of islands are often associated with rapid morphological divergence. We present two previously unrecog-nized cases of dramatic morphological change and niche shifts in connection with colonization of tropical ...
    • Building a responsive teacher 

      Lee, Hanju; Kanakogi, Yasuhiro; Hiraki, Kazuo (2015)
      Animated pedagogical agents are lifelike virtual characters designed to augment learning. A review of developmental psychology literature led to the hypothesis that the temporal contingency of such agents would promote ...
    • Assessing costs of carrying geolocators using feather corticosterone in two species of aerial insectivore 

      Fairhurst, Graham D.; Berzins, Lisha L.; Bradley, David W. (2015)
      Despite benefits of using light-sensitive geolocators to track animal movements and describe patterns of migratory connectivity, concerns have been raised about negative effects of these devices, particularly in small ...
    • African origin for Madagascan dogs revealed by mtDNA analysis 

      Ardalan, Arman; Oskarsson, Mattias C. R.; Asch, Barbara Van (2015)
      Madagascar was one of the last major land masses to be inhabited by humans. It was initially colonized by Austronesian speaking Indonesians 1500–2000 years ago, but subsequent migration from Africa has resulted in approximately ...
    • Coordination nano space as stage of hydrogen ortho para conversion 

      Kosone, Takashi; Hori, Akihiro; Nishibori, Eiji (2015)
      The ability to design and control properties of nano-sized space in porous coordination polymers (PCPs) would provide us with an ideal stage for fascinating physical and chemical phenomena. We found an interconversion of ...
    • Initiation and spread of escape waves within animal groups 

      Herbert-Read, James E.; Buhl, Jerome; Hu, Feng (2015)
      The exceptional reactivity of animal collectives to predatory attacks is thought to be owing to rapid, but local, transfer of information between group members. These groups turn together in unison and produce escape waves. ...
    • A pheromone outweighs temperature in influencing migration of sea lamprey 

      Brant, Cory O. (2015)
      Organisms continuously acquire and process information from surrounding cues. While some cues complement one another in delivering more reliable information, others may provide conflicting information. How organisms extract ...
    • Crypsis via leg clustering 

      Zhang, Shichang (2015)
      The role of background matching in camouflage has been extensively studied. However, contour modification has received far less attention, especially in twig-mimicking species. Here, we studied this deceptive strategy by ...
    • Taking a closer look 

      Holzwarth, Frédéric; Rüger, Nadja; Wirth, Christian (2015)
      Biodiversity and ecosystem functioning (BEF) research has progressed from the detection of relationships to elucidating their drivers and underlying mechanisms. In this context, replacing taxonomic predictors by trait-based ...
    • Uncomfortable images produce non-sparse responses in amodel of primary visual cortex 

      Hibbard, Paul B.; O’Hare, Louise (2015)
      The processing of visual information by the nervous system requires significant metabolic resources. To minimize the energy needed, our visual system appears to be optimized to encode typical natural images as efficiently ...
    • Improved community detection inweighted bipartite networks 

      Beckett, Stephen J. (2016)
      Real world complex networks are composed of non random quantitative interactions. Identifying communities of nodes that tend to interact more with each other than the network as a whole is a key research focus across ...
    • The missing metric 

      Cantor, Maurício; Gero, Shane (2015)
      The number of contributing reviewers often outnumbers the authors of publications. This has led to apathy towards reviewing and the conclusion that the peer-review system is broken. Given the trade-offs between submitting ...
    • RNA directed epigenetic silencing of Periostin inhibits cell motility 

      Lister, Nicholas C.; Clemson, Matthew; Morris, Kevin V. (2015)
      The over-expression of Periostin, a member of the fasciclin family of proteins, has been reported in a number of cancers and, in particular, in metastatic tumours. These include breast, ovarian, lung, colon, head and neck, ...
    • Dynamics of osmosis in a porous medium 

      Cardoso, Silvana S. S.; Cartwright, Julyan H. E. (2014)
      We derive from kinetic theory, fluid mechanics and thermodynamics the minimal continuum-level equations governing the flow of a binary, non-electrolytic mixture in an isotropic porous medium with osmotic effects. For dilute ...
    • Pre-zygotic isolation in the macroalgal genusFucus from four contact zones spanning 100–10 000 years 

      Hoarau, G.; Coyer, J.A.; Giesbers, M.C.W.G. (2015)
      Hybrid zones provide an ideal natural experiment to study the selective forces driving evolution of reproductive barriers and speciation. If hybrid offspring are less fit than the parental species, pre-zygotic isolating ...
    • Environmental offsets, resilience and cost effective conservation 

      Little, L. R.; Grafton, R. Q. (2015)
      Conservation management agencies are faced with acute trade-offs when dealing with disturbance from human activities. We show how agencies can respond to permanent ecosystem disruption by managing for Pimm resilience within ...
    • Approximate series solution of multi-dimensional, time fractional-order (heat-like) diffusion equations using FRDTM 

      Singh, Brajesh K.; Srivastava, Vineet K. (2015)
      The main goal of this paper is to present a new approximate series solution of the multi-dimensional (heat-like) diffusion equation with time-fractional derivative in Caputo form using a semi-analytical approach: ...
    • Resumption of traditional drive hunting of dolphins in the Solomon Islands in 2013 

      Oremus, Marc (2015)
      The ‘drive hunting’ of dolphins has a long history in the Solomon Islands, specifically at the island of Malaita. In 2010, the most active village, Fanalei, suspended hunting in exchange for financial compensation from an ...
    • Computational model of collective nest selection by ants with heterogeneous acceptance thresholds 

      Masuda, Naoki (2015)
      Collective decision-making is a characteristic of societies ranging from ants to humans. The antTemnothorax albipennisis known to use quorum sensing to collectively decide on a new home emigration to a new nest site occurs ...
    • Experimental evidence for convergent evolution of maternal care heuristics in industrialized and small-scale populations 

      Kushnick, Geoff; Hanowell, Ben; Kim, Jun Hong (2015)
      Maternal care decision rules should evolve responsiveness to factors impinging on the fitness pay-offs of care. Because the caretaking environments common in industrialized and small-scale societies vary in predictable ...
