Dopamine regulates termite soldier differentiation through trophallactic behaviours
(2016)Caste polyphenism in social insects is regulated by social interactions among colony members. Trophallaxis is one of the most frequently observed interactions, but no studies have been conducted identifying the intrinsic ... -
Kinship as a frequency dependent strategy
(2016)Humans divide themselves up into separate cultures, which is a unique and ubiquitous characteristic of our species. Kinship norms are one of the defining features of such societies. Here we show how norms of marital residence ... -
The Peer Reviewers’ Openness Initiative
(2016)Openness is one of the central values of science. Open scientific practices such as sharing data, materials and analysis scripts alongside published articles have many benefits, including easier replication and extension ... -
Proprioceptive feedback determines visuomotor gain in Drosophila
(2016)Multisensory integration is a prerequisite for effective locomotor control in most animals. Especially, the impressive aerial performance of insects relies on rapid and precise integration of multiple sensory modalities ... -
Smooth enlargement of human standing sway by instability due toweak reaction floor and noise
(2016)Human quiet standing is accompanied by body sway. The amplitude of this body sway is known to be larger than would be predicted from simple noise effects, and sway characteristics are changed by neurological disorders. ... -
Exploration adjustment Ants determine their next move at rest
(2016)To find useful work to do for their colony, individual eusocial animals have to move, somehow staying attentive to relevant social information. Recent research on individual Temnothorax albipennis ants moving inside their ... -
Oviposition preference of cabbage white butterflies in the framework of costs and benefits of interspecific herbivore associations
(2015)When deciding where to oviposit, herbivorous insects consider: (i) the plant’s value as a food source, (ii) the risks of competing with con- and heterospecific herbivores, and (iii) the risks of parasitism and predation ... -
Comparison of social structures within cities of very different sizes
(2016)People make a city, making each city as unique as the combination of its inhabitants. However, some cities are similar and some cities are inimitable. We examine the social structure of 10 different cities using Twitter ... -
Trophic niche divergence among colour morphs that exhibit alternative mating tactics
(2016)Discrete colour morphs associated with alternative mating tactics are assumed to be ecologically equivalent. Yet suites of behaviours linked with reproduction can also favour habitat segregation and exploitation of different ... -
Exploration adjustment by ant colonies
(2016)How do animals in groups organize their work? Division of labour, i.e. the process by which individuals within a group choose which tasks to perform, has been extensively studied in social insects. Variability among ... -
Parental influence on begging call structure in zebra finches
(2015)Begging calls are signals of need used by young birds to elicit care from adults. Different theoretical frameworks have been proposed to understand this parent–offspring communication. But relationships between parental ... -
Lack of experience based stratification in homing pigeon leadership hierarchies
(2016)In societies that make collective decisions through leadership, a fundamental question concerns the individual attributes that allow certain group members to assume leadership roles over others. Homing pigeons form transitive ... -
Prolonged transition time between colostrumand maturemilk in a bear, the giant panda,Ailuropoda melanoleuca
(2015)Bears produce the most altricial neonates of any placental mammal. We hypothesized that the transition from colostrum to mature milk in bears reflects a temporal and biochemical adaptation for altricial development and ... -
Sexually selected lip colour indicates male group holding status in themating season in a multi-level primate society
(2015)Sexual selection typically produces ornaments in response to mate choice, and armaments in response to male–male competition. Unusually among mammals, many primates exhibit colour signals that may be related to one or both ... -
Satellite tracking reveals novel migratory patterns and the importance of seamounts for endangered South Pacific humpback whales
(2015)The humpback whale population of New Caledonia appears to display a novel migratory pattern characterized by multiple directions, long migratory paths and frequent pauses over seamounts and other shallow geographical ... -
Loss of reproductive output caused by an invasive species
(2016)We investigated whetherNeogobius melanostomus,aninvader of biodiversity ‘hot-spots’ in the Laurentian Great Lakes region, facilitates or inhibits unionid mussel recruitment by serving as a host or sink for their parasitic ... -
On the convergence and accuracy of the cardiovascular intrinsic frequencymethod
(2015)In this paper, we analyse the convergence, accuracy and stability of the intrinsic frequency (IF) method. The IF method is a descendant of the sparse time frequency representation methods. These methods are designed for ... -
She more than he: gender bias supports the empathic nature of yawn contagion in Homo sapiens
(2016)Psychological clinical and neurobiological findings endorse that empathic abilities are more developed in women than in men. Because there is growing evidence that yawn contagion is an empathy-based phenomenon, we expect ... -
Arithmetic for College Students
(Opentextbookstore, 2014)This book is a course on arithmetic designed for college students. It covers whole numbers, fractions, decimals, percents, ratios and proportions, measurement, and integers. Geometry and statistics are integrated throughout ... -
Beginning and Intermediate Algebra
(Opentextbookstore, 2010)Beginning and Intermediate Algebra was designed to reduce textbook costs to students while not reducing the quality of materials. This text includes many detailed examples for each section along with several problems for ...
