THE EVOLUTION OF HOMO LUDENS: SEXUAL SELECTION AND A THEOLOGY OF PLAY

open access: yesZygon, 2022
This essay argues that reflection on sexual selection can be theologically generative, and that it presents needed counteremphases to some of the discussions about theological anthropology that have been fueled by theological reflection on natural ...

Post-insemination selection dominates pre-insemination selection in driving rapid evolution of male competitive ability.

open access: yesPLoS Genetics, 2022
Sexual reproduction is a complex process that contributes to differences between the sexes and divergence between species. From a male's perspective, sexual selection can optimize reproductive success by acting on the variance in mating success (pre ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Runaway sexual selection without genetic correlations : social environments and flexible mate choice initiate and enhance the Fisher process

open access: yes, 2012
Female mating preferences are often flexible, reflecting the social environment in which they are expressed. Associated indirect genetic effects (IGEs) can affect the rate and direction of evolutionary change, but sexual selection models do not capture ...

Serum Myonectin Levels Are Positively Associated With Physical Function and Lower Frailty‐Related Limitation in Maintenance Hemodialysis Patients: A Cross‐Sectional Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

Presentation: Sexual Selection

open access: yes, 2001
Darwin’s second great theory, sexual selection, attempts to explain why males are males and females are females. In this lecture Dr. Michael Ryan explores the diversity of differences between male and female animals, asks why such differences have ...

Impacts of sperm competition on mating behaviour and life history traits in a simultaneous hermaphrodite [PDF]

open access: yes, 2013
Evolutionary theory suggests that post-copulatory sexual selection plays an important role in the evolution of reproductive traits of sexually reproducing animals.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Understanding the evolution of ecological sex differences: Integrating character displacement and the Darwin‐Bateman paradigm

open access: yesEvolution Letters, 2019
Sex differences in selection arise for at least two possible reasons: (1) differences originating from anisogamy—the Darwin‐Bateman paradigm—and (2) competition‐driven ecological character displacement (ECD), agnostic of anisogamy.

Sexual Selection: Copycat Mating in Birds [PDF]

open access: yesCurrent Biology, 2005
Female zebra finches may be influenced by the choices of other females when selecting mates, challenging the view that mate-choice copying should not occur in species with biparental care.
