Abstract:

Wildlife demography is typically studied at a single point in time within a year when species, often during the reproductive season, are more active and therefore easier to find. However, this provides only a low-resolution glimpse into demographic temporal patterns over time and may hamper a more complete understanding of the population dynamics of a species over the full annual cycle. The full annual cycle is often influenced by environmental seasonality, which induces a cyclic behavior in many species. However, cycles have rarely been explicitly included in models for demographic parameters

Abstract:

Cliodynamics is a still a relatively new research area with the purpose of investigating and modelling historical processes. One of its first important mathematical models was proposed by Turchin and called “Demographic-Fiscal Model” (DFM). This DFM was one of the first and is one of a few models that link population with state dynamics. In this work, we propose a possible alternative to the classical Turchin DFM, which contributes to further model development and comparison essential for the field of cliodynamics. Our “Demographic-Wealth Model” (DWM) aims to also model link between population

Abstract:

Host immunity and demographics (the recruitment of susceptibles via birthrate) have been demonstrated to be a key determinant of the periodicity of measles, pertussis and dengue epidemics. However, not all epidemic cycles are from pathogens inducing sterilizing immunity or are driven by demographics. Many sexually transmitted infections are driven by sexual behaviour. We present a mathematical model of disease transmission where individuals can disconnect and reconnect depending on the infectious status of their contacts. We fit the model to historic syphilis ( Treponema pallidum ) and gonorrh

Abstract:

This article explores the nature of record linkage in conventional family reconstitution studies, building upon previous pieces in this journal. It argues that the record linkage process on which reconstitution is based compromises the results obtained in two ways. First, it generates bias in the types of life-cycle detected. Second, because it assumes that potential links without obvious competition should be made, it generates a range of incorrect linkages. This article suggests that a better approach to life and demography in early modern communities might lie in the reconstruction of enric

We present raw tabulations and estimate a state panel data model that leverages variation across U.S. states in the timing and severity of business cycles.

A comparative, diachronic analysis of urban population dynamics allows for the identification of specific demographic trajectories influencing metropolitan expansion worldwide.

Abstract:

Seasonal variation in the abundance of marine plankton taxa is commonly expressed in the form of ‘mean annual cycles', in which the mean abundance over several years for a particluar season is plotted against the time of year. Typically, such mean annual cycles are used to compare patterns between different spatial locations. We wish to argue, however, that this can be very misleading since the shape of the underlying seasonal cycle itself may change with time as well as location. Thus, it is possible that the mean annual cycle may never actually occur in the environment in any location, nor n

For this purpose, three indicators are studied – demographic, social, and economical. The thesis is that the extermination will most likely occur in 2035-2043 when risk factors are superimposed both from the descending phase of the next generation cycle of Simon Kuznets and from the ascending phase of the US military budget.

Abstract:

This study aims to compare endometrial growth before and after the addition of human growth hormone (hGH) in controlled ovarian hyperstimulation (COH) cycles. A 5-year retrospective cohort study of patients treated with hGH to improve oocyte development during COH cycles was conducted. Each patient’s cycle without hGH immediately preceding cycle(s) with hGH was used for patients to serve as their own controls. Primary outcome was absolute growth in endometrial thickness from pre-stimulation start to day of hCG trigger. Mixed-model regression analysis controlled for patient correlation over rep

Abstract:

This study provides theoretical stock-recruitment relationships for life cycles in which multiple, density-dependent mechanisms stemming from different periods during the life cycle act concurrently on a single demographic transition. Using graphical examples and analytical derivations, it is demonstrated that overcompensatory density dependence emerges from such life cycles despite the initial assumption that density-dependent mechanisms follow simple compensatory Beverton-Holt dynamics. These results indicate that concurrent demographic effects of temporally distinct density-dependent mechan

Abstract:

Allgeier and Cline suggest that our model overestimates the contributions of cryptobenthic fishes to coral reef functioning. However, their 20-year model ignores the basic biological limits of population growth. If incorporated, cryptobenthic contributions to consumed fish biomass remain high (20 to 70%). Disturbance cycles and uncertainties surrounding the fate of large fishes on decadal scales further demonstrate the important role of cryptobenthic fishes.

Abstract:

Cycles, such as seasons or tides, characterize many systems in nature. Overwhelming evidence shows that climate change-driven alterations to environmental cycles—such as longer seasons—are associated with phenological shifts around the world, suggesting a deep link between environmental cycles and life cycles. However, general mechanisms of life-history evolution in cyclical environments are still not well understood. Here, I build a demographic framework and ask how life-history strategies optimize fitness when the environment perturbs a structured population cyclically and how strategies sho

Abstract:

Background and Aims: Embryo quality is directly related to pregnancy rate as previously demonstrated by CHLOE-EQ. CHLOE-EQ Score is an automatic embryo viability score provided by CHLOE (Fairtility). It might provide key performance indicators (KPI) to measure how different protocols impact embryo quality. KPIs are objective measures for systematically monitoring and evaluating the IVF laboratory, a critical element of every IVF clinic Quality Management System. KPIs currently rely on definitions which are simple to assess (fertilisation, cleavage, blastulation), we do not routinely use other
