Sex and recombination in the H\"otzel aging model

, 2003
Why sex evolved and it prevails in nature remains one of the great puzzles of evolution. Most biologists would explain that it promotes genetic variability, however this explanation suffers from several difficulties. What advantages might sex confer? The

Long‐term monitoring reveals biomass loss and concurrent dominance changes in coastal zooplankton community

Ecography, EarlyView.
Anthropogenically induced changes in environmental conditions have been affecting species communities globally, leading to shifts in ecosystem functioning. Physical drivers like temperature, salinity and acidification are especially important in coastal ecosystems, and high‐resolution time‐series are essential to identify how these variables affect ...

Asexual reproduction and vegetative growth of Bionectria ochroleuca in response to temperature and photoperiod

Ecology and Evolution, 2021
Growth and reproduction are two essential life‐history traits for fungi. Understanding life‐history strategies provides insight into the environmental adaption of species.

Is Parthenogenesis Sexual or Asexual Reproduction? [PDF]

Nature, 1950
CYTOLOGISTS and others commonly refer to parthenogenesis as asexual reproduction. This usage is, for example, to be found in the books of Wilson1, Darlington2, and White3, along with the facts that indicate that parthenogenesis is a derivative of normal sexual reproduction.

Age‐Related Trends in Eating‐Pathology Symptoms Among Sexual Minority Adults

European Eating Disorders Review, EarlyView.
ABSTRACT Objective To examine how eating‐disorder symptoms vary by chronological age and sexual orientation in sexual minority adults. Method Cross‐sectional data came from 2062 cisgender sexual minority participants (925 gay men, 573 lesbian women, 116 bi+ men, 448 bi+ women; age = 47.8 years, range = 18–96).

Reproduction-associated pathways in females of gibel carp (Carassius gibelio) shed light on the molecular mechanisms of the coexistence of asexual and sexual reproduction

BMC Genomics
Gibel carp (Carassius gibelio) is a cyprinid fish that originated in eastern Eurasia and is considered as invasive in European freshwater ecosystems. The populations of gibel carp in Europe are mostly composed of asexually reproducing triploid females (i.

Mating-type genes of the anamorphic fungus Ulocladium botrytis affect both asexual sporulation and sexual reproduction

Scientific Reports, 2017
Ulocladium was thought to be a strictly asexual genus of filamentous fungi. However, Ulocladium strains were shown to possess both MAT1-1-1 and MAT1-2-1 genes as observed in homothallic filamentous Ascomycetes. Here, we demonstrate that the U.

Simulated Coevolution in a Mutating Ecology

, 2000
The bit-string Penna Model is used to simulate the competition between an asexual parthenogenetic and a sexual population sharing the same environment. A new-born of either population can mutate and become a part of the other with some probability.

Queer configurations: The female divine, regional identity, and Queer‐religious belonging in South India

Feminist Anthropology, EarlyView.
Abstract This article explores how queerness and religion intersect in a unique enactment of Bathukamma, a flower festival honoring the female divine in Hyderabad, the capital of the South Indian state of Telangana. Drawing on theories of figuration, I analyze how local queer organizations celebrate the festival in a way that engages two distinctive ...

A key role for sex chromosomes in the regulation of parthenogenesis in the brown alga Ectocarpus.

PLoS Genetics, 2019
Although evolutionary transitions from sexual to asexual reproduction are frequent in eukaryotes, the genetic bases of these shifts remain largely elusive.
