The Ibis, journal of the British Ornithologists' Union : a pre-synthesis portrait

Creator:: Johnson, Kristin Renee
Abstract:: In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...

Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

Creator:: Coblentz, Kyle E.
Abstract:: Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

Metrics of positive scalar curvature and generalised Morse functions, Part II

Creator:: Walsh, Mark
Abstract:: The surgery technique of Gromov and Lawson may be used to construct families of positive scalar curvature metrics which are parameterised by Morse functions. This has played an important role in the study of the space of metrics of positive scalar curvature on a smooth manifold and its corresponding moduli...

On normalized multiplicative cascades under strong disorder

Creator:: Dey, Partha S. and Waymire, Edward C.
Abstract:: The purpose of this note is to provide a coupling of weak limits in distribution of sequence of (normalized) multiplicative cascade measures under strong disorder in terms of the extremes of an associated branching random walk, assuming i.i.d positive, non-lattice bond weights and a second moment condition. The solution is...

Inequivalent Cantor sets in 𝑅³ whose complements have the same fundamental group

Creator:: Garity, Dennis J. and Repovš, Dušan
Abstract:: For each Cantor set C in R³, all points of which have bounded local genus, we show that there are infinitely many inequivalent Cantor sets in R³ with the complement having the same fundamental group as the complement of C. This answers a question from Open Problems in Topology and...

Male Greater Sage-Grouse Detectability on Leks

Creator:: Fremgen, Aleshia L.
Abstract:: It is unlikely all male sage-grouse are detected during lek counts, which could complicate the use of lek counts as an index to population abundance. Understanding factors that influence detection probabilities will allow managers to more accurately estimate the number of males present on leks. We fitted 410 males with...

The Mathematics of Critical Shifts in Ecological Networks with Alternative Stable State Theory, A Potential Framework for Early Warning Indicators

Creator:: Kupperman, Michael D.
Abstract:: A long running problem in mathematical biology is the prediction of extinction events, a specialized case of the larger global stability problem found in differential equations and dynamical systems theory. A central technical question is how to introduce the randomness observed in real ecological systems not accounted for in deterministic...

Ribonucleotide reductase and thymidylate synthase or exogenous deoxyribonucleosides reduce DNA damage and senescence caused by C‐MYC depletion

Creator:: Mannava, Sudha, Moparthy, Kalyana C., Wheeler, Linda J., Leonova, Katerina I., Wawrzyniak, Joseph A., Bianchi-Smiraglia, Anna, Berman, Albert E., Flanagan, Sheryl, Shewach, Donna S., Zeitouni, Nathalie C., Gudkov, Andrei V., Mathews, Christopher K., and Nikiforov, Mikhail A.
Abstract:: The down‐regulation of dominant oncogenes, including C‐MYC, in tumor cells often leads to the induction of senescence via mechanisms that are not completely identified. In the current study, we demonstrate that MYC‐depleted melanoma cells undergo extensive DNA damage that is caused by the underexpression of thymidylate synthase (TS) and ribonucleotide...

The Impact of Imitation on Vaccination Behavior in Social Contact Networks

Creator:: Mbah, Martial L. Ndeffo, Liu, Jingzhou, Bauch, Chris T., Tekel, Yonas I., Medlock, Jan, Meyers, Lauren Ancel, and Galvani, Alison P.
Abstract:: Previous game-theoretic studies of vaccination behavior typically have often assumed that populations are homogeneously mixed and that individuals are fully rational. In reality, there is heterogeneity in the number of contacts per individual, and individuals tend to imitate others who appear to have adopted successful strategies. Here, we use network-based...

Localized Structures in a Diffusive Run-and-Tumble Model of Myxococcus xanthus

Creator:: Flynn, Patrick Thomas
Abstract:: The bacteria Myxococcus xanthus clusters into fruiting bodies in the absence of food. The movement of M. xanthus has three aspects: self-propulsion (run), change of direction due to collision (tumble), and Brownian fluctuations in movement. We propose a minimalist PDE model for the concentrations of left and right moving agents...
