    • The relationship between pond habitat depth and functional tadpole diversity in an agricultural landscape 

      Queiroz, Cássia de Souza (2015)
      One of the most important goals of biodiversity studies is to identify which characteristics of local habitats act as filters that determine the diversity of functional traits along environmental gradients. In this study, ...
    • Models of fertilization kinetics 

      Lehtonen, Jussi (2015)
      Fertilization functions describe how the number of realized fertilizations depends on gamete numbers or density. They provide insight into the fertilization process, and are important components in models on the evolution ...
    • What’s the catch? 

      V. Ivashchenko, Yulia; J. Clapham, Phillip (2015)
      The failure of international efforts to manage commercial whaling was exemplified by revelations of large-scale illegal whale catches by the USSR over a 30 year period following World War II. Falsifications of catch data ...
    • Incubator-independent cell-culture perfusion platform for continuous long-termmicroelectrode array electrophysiology and time-lapse imaging 

      Saalfrank, Dirk; Konduri, Anil Krishna; Latifi, Shahrzad (2015)
      Mostin vitro electrophysiology studies extract information and draw conclusions from representative, temporally limited snapshot experiments. This approach bears the risk of missing decisive moments that may make a difference ...
    • A phylogenomic analysis of the role and timing of molecular adaptation in the aquatic transition of cetartiodactyl mammals 

      Tsagkogeorga, Georgia; McGowen, Michael R.; Davies, Kalina T. J. (2015)
      Recent studies have reported multiple cases of molecular adaptation in cetaceans related to their aquatic abilities. However, none of these has included the hippopotamus, precluding an understanding of whether molecular ...
    • Phylogenetic tests reject Emery’s rule in the evolution of social parasitism in yellowjackets and hornets 

      Lopez-Osorio, Federico; Perrard, Adrien; Pickett, Kurt M. (2015)
      Social parasites exploit the brood-care behaviour and social structure of one or more host species. Within the social Hymenoptera there are different types of social parasitism. In its extreme form, species of obligate ...
    • Tools to tipple 

      Hockings, Kimberley J. (2015)
      African apes and humans share a genetic mutation that enables them to effectively metabolize ethanol. However, voluntary ethanol consumption in this evolutionary radiation is documented only in modern humans. Here, we ...
    • Proximate causes of the red face of the bald uakari monkey 

      Mayor, P.; Mamani, J.; Montes, D. (2015)
      In social species, such as primates, facial appearances transmit a variety of social signals. Although it is suggested that the intense red colour of the face of the bald uakari monkey might be an indicator of health, this ...
    • Yes, it turns 

      Gueguen, Yannick; Czorlich, Yann; Mastail, Max (2015)
      Cultured pearls are human creations formed by inserting a nucleus and a small piece of mantle tissue into a living shelled mollusc, usually a pearl oyster. Although many pearl observations intuitively suggest a possible ...
    • Iconicity can ground the creation of vocal symbols 

      Perlman, Marcus; Dale, Rick; Lupyan, Gary (2015)
      Studies of gestural communication systems find that they originate from spontaneously created iconic gestures. Yet, we know little about how people create vocal communication systems, and many have suggested that vocalizations ...
    • Nest inundation from sea-level rise threatens sea turtle population viability 

      Pike, David A.; Roznik, Elizabeth A.; Bell, Ian (2015)
      Contemporary sea-level rise will inundate coastal habitats with seawater more frequently, disrupting the life cycles of terrestrial fauna well before permanent habitat loss occurs. Sea turtles are reliant on low-lying ...
    • Detecting somatic mutations in genomic sequences bymeans of Kolmogorov Arnold analysis 

      Gurzadyan, V. G.; Yan, H.; Vlahovic, G. (2015)
      The Kolmogorov–Arnold stochasticity parameter technique is applied for the first time to the study of cancer genome sequencing, to reveal mutations. Using data generated by next-generation sequencing technologies, we have ...
    • Chromosome interaction over a distance inmeiosis 

      Brady, Mary; Paliulis, Leocadia V. (2015)
      The challenge of cell division is to distribute partner chromosomes (pairs of homologues, pairs of sex chromosomes or pairs of sister chromatids) correctly, one into each daughter cell. In the ‘standard’ meiosis, this ...
    • Rethinking competence inmarine life cycles 

      Hodin, Jason; Ferner, Matthew C.; Ng, Gabriel (2015)
      Complex life cycles have evolved independently numerous times in marine animals as well as in disparate algae. Such life histories typically involve a dispersive immature stage followed by settlement and metamorphosis to ...
    • A global optimization paradigmbased on change of measures 

      Sarkar, Saikat; Roy, Debasish; Vasu, Ram Mohan (2015)
      A global optimization framework, COMBEO (Change Of MeasureBasedEvolutionaryOptimization), is proposed. An important aspect in the development is a set of derivative-free additive directional terms, obtainable through a ...
    • Activation of an inflammatory response is context-dependent during early development of the California sea lion 

      Vera-Massieu, Camila; Brock, Patrick M.; Godínez-Reyes, Carlos (2015)
      Variations in immune function can arise owing to trade-offs, that is, the allocation of limited resources among costly competing physiological functions. Nevertheless, there is little information regarding the ontogeny of ...
    • Efficient expansion of global protected areas requires simultaneous planning for species and ecosystems 

      Polak, Tal; Watson, James E.M.; Fuller, Richard A. (2015)
      The Convention on Biological Diversity (CBD)’s strategic plan advocates the use of environmental surrogates, such as ecosystems, as a basis for planning where new protected areas should be placed. However, the efficiency ...
    • Cities and regions in Britain through hierarchical percolation 

      Arcaute, Elsa; Molinero, Carlos; Hatna, Erez (2016)
      Urban systems present hierarchical structures at many different scales. These are observed as administrative regional delimitations which are the outcome of complex geographical, political and historical processes which ...
    • Tight knit under stress 

      Kolay, Swetashree; Annagiri, Sumana (2015)
      The movement of colonies from one nest to another is a frequent event in the lives of many social insects and is important for their survival and propagation. This goal-oriented task is accomplished by means of tandem ...
    • Tracking urban activity growth globally with big location data 

      Daggitt, Matthew L.; Noulas, Anastasios; Shaw, Blake (2016)
      In recent decades, the world has experienced rates of urban growth unparalleled in any other period of history and this growth is shaping the environment in which an increasing proportion of us live. In this paper, we use ...
