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 ... -
Saylor MA 304 Topics in Applied Mathematics
(2013)Mathematics was coined the queen of sciences by Carl Friedrich Gauss, one of the greatest mathematicians of all time. The name of Gauss is associated with essentially all areas of mathematics. Therefore to him, and most ... -
A scenario for the evolution of selective egg coloration
(2016)Behavioural plasticity can drive the evolution of new traits in animals. In oviparous species, plasticity in oviposition behaviour could promote the evolution of new egg traits by exposing them to different selective ... -
Seasonal and ontogenetic variation of skinmicrobial communities and relationships to natural disease dynamics in declining amphibians
(2015)Recently, microbiologists have focused on characterizing the probiotic role of skin bacteria for amphibians threatened by the fungal disease chytridiomycosis. However, the specific characteristics of microbial diversity ... -
Seasonal changes in the altitudinal distribution of nocturnallymigrating birds during autumnmigration
(2015)Wind plays a significant role in the flight altitudes selected by nocturnally migrating birds. At mid-latitudes in the Northern Hemisphere, atmospheric conditions are dictated by the polar-front jet stream, whose amplitude ... -
Seasonal dynamics of megafauna on the deep West Antarctic Peninsula shelf in response to variable phytodetrital influx
(2014)The deep West Antarctic Peninsula (WAP) shelf is characterized by intense deposition of phytodetritus during spring/summer months, while very little food material reaches the seafloor during winter. The response of the ... -
Segregated water observed in a putative fish embryo cryopreservative
(2016)Development of new cryopreservation strategies has major potential in medicine and agriculture and is critical to the conservation of endangered species that currently cannot be preserved. A critical property of any potential ... -
Self motion facilitates echo acoustic orientation in humans
(2014)The ability of blind humans to navigate complex environments through echolocation has received rapidly increasing scientific interest. However, technical limitations have precluded a formal quantification of the interplay ... -
Self organized flexible leadership promotes collective intelligence in human groups
(The Royal Society, 2015)Collective intelligence refers to the ability of groups to outperform individual decision-makers. At present, relatively little is known about the mechanisms promoting collective intelligence in natural systems. We here ... -
Selfishmothers indeed. Resource-dependent conflict over extended parental care in free-ranging dogs
(2015)Parent off spring conflict (POC) theory provides an interesting premise for understanding social dynamics in facultatively social species. In free-ranging dogs, mothers increase conflict over extended parental care with ... -
A Sensors System for Indoor Localisation of a Moving Target Based on Infrared Pattern Recognition
(INTECH Open Access Publisher, 2007)A novel method for the indoor localisation of a target was presented in this chapter. This method is based on measuring the number of the digital infrared patterns received by the target in a specific time interval (success ... -
A severe red tide causes an anomalous decrease in biological sound
(2015)Although harmful algal blooms (HABs) are known to cause morbidity and mortality in marine organisms, their sublethal effects are poorly understood. The purpose of this study was to compare ambient noise levels during a ... -
Sex and hibernaculum temperature predict survivorship inwhite-nose syndrome affected little brownmyotis
(The Royal Society, 2015)White-nose syndrome (WNS), an emerging infectious disease caused by the novel fungus Pseudogymnoascus destructans,has devastated North American bat populations since its discovery in 2006. The little brown myotis,Myotis ... -
Sex differences in risk-taking and associative learning in rats
(2015)In many species, males tend to have lower parental investment than females and greater variance in their reproductive success. Males might therefore be expected to adopt more high-risk, high-return behaviours than females. ... -
Sex ratio effects on reproductive strategies in humans
(2015)Characterizations of coy females and ardent males are rooted in models of sexual selection that are increasingly outdated. Evolutionary feedbacks can strongly influence the sex roles and subsequent patterns of sex ... -
Sexual reproduction with variablemating systems can resist asexuality in a rock–paper–scissors dynamics
(The Royal Society, 2015)While sex can be advantageous for a lineage in the long term, we still lack an explanation for its maintenance with the twofold cost per generation. Here we model an infinite diploid population where two autosomal loci ... -
Sexual selection of male parental care in giant water bugs
(2016)Paternal care can be maintained under sexual selection, if it helps in attracting more mates. We tested the hypothesis in two giant water bug species,Appasus majorandAppasus japonicus, that male parental care is sexually ... -
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 ... -
Shared Escovopsis parasites between leaf cutting and non leaf cutting ants in the higher attine fungus growing ant symbiosis
(2015)Fungus-gardening (attine) ants grow fungus for food in protected gardens, which contain beneficial, auxiliary microbes, but also microbes harmful to gardens. Among these potentially pathogenic microorganisms, the most ... -
Sharpening coarse-to-fine stereo vision by perceptual learning
(2016)Neurons in the early visual cortex are finely tuned to different low-level visual features, forming a multi-channel system analysing the visual image formed on the retina in a parallel manner. However, little is known about ...
