Abstract:
Cet article aborde la question du genre en relisant les choses à la lumière du développement psychique de la sexualité de l’être humain. La métapsychologie ne répond pas à la question de savoir comment le sexe vient aux uns et aux autres ni à celle de savoir s’il devrait exister une sortie de la binarité masculin-féminin. Car, pour la métapsychologie, la pulsion sexuelle, présente dès le début, se constitue pour chacun non seulement à l’aune des deux genres connus : bisexualité psychique, mais également de manière multiple selon le sujet, son histoire.

This critical autoethnography explores experiences as an asexual cismale and the inherent tensions and struggles experienced in the dialectic between societal expectations of sexual desire as a man and the lack of sex drive characteristic of an asexual orientation. It explores the exclusion asexuals experience, as they occupy a third space between straightness and queerness, leaving them nowhere in either the gender or sexuality roles spectrums to truly call home. As asexuals exist in a space not often considered by heterosexual and queer individuals and asexual men exist between the tension o

Abstract:
The Red Queen hypothesis (RQH) is one of the most widely accepted hypotheses explaining the persistence of sexual reproduction despite its costs. It posits that sexual species, compared with asexuals, are more adept at countering parasites, because their per-generation recombination rate is higher. Despite theoretical support, current empirical studies have failed to provide unanimous support. Here, we suggest that future tests of the RQH should more thoroughly elucidate its underlying assumptions and potential alternative hypotheses. While the RQH predicts that negative frequency-dependent se

Abstract:
We present a model for the maintenance of sexual reproduction based on the availability of resources, which is the strongest factor determining the growth of populations. The model compares completely asexual species to species that switch between asexual and sexual reproduction (sexual species). Key features of the model are that sexual reproduction sets in when resources become scarce, and that at a given place only a few genotypes can be present at the same time. We show that under a wide range of conditions the sexual species outcompete the asexual ones. The asexual species win only when s

Abstract:
The factors contributing to the maintenance of sex over asexuality in natural populations remain unclear. Ecological divergences between sexual and asexual lineages could help to maintain reproductive polymorphisms, at least transiently, but the consequences of asexuality for the evolution of ecological niches are unknown. Here, we investigated how niche breadths change in transitions from sexual reproduction to asexuality. We used host plant ranges as a proxy to compare the realized feeding niche breadths of five independently derived asexual Timema stick insect species and their sexual relat

Abstract:
In sperm-dependent sexual/asexual mating systems, male mate choice is critical for understanding the mechanisms behind apparent stability observed in natural populations. The gynogenetic Amazon molly ( Poecilia formosa ) requires sperm from sexual males (e.g. Poecilia latipinna ) to trigger embryogenesis, but inheritance is strictly maternal. Consequently, males should try to avoid or reduce the cost of mating with asexuals. We investigated male mate choice by documenting the presence of sperm in natural populations and found that a higher proportion of sexual females had sperm than asexuals.

Abstract:
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 determine, respectively, the reproductive mode, sexual versus asexual and the mating system, polygynous (costly sex) versus monogamous (assuming equal contribution of parents to offspring, i.e. non-costly sex). We show that alleles for costly sex can spread when non-costly sexual modes buffer the interaction between asexual and costly sexual strategies, even without twofold bene

Abstract:
BackgroundCoexistence of sexual and asexual populations remains a key question in evolutionary ecology. We address the question how an asexual and a sexual form of the parasitoidVenturia canescenscan coexist in southern Europe. We test the hypothesis that both forms are adapted to different habitats within their area of distribution. Sexuals inhabit natural environments that are highly unpredictable, and where density of wasps and their hosts is low and patchily distributed. Asexuals instead are common in anthropic environments (e.g., grain stores) where host outbreaks offer periods when egg-l

Abstract:
The high prevalence of sexual reproduction is considered a paradox mainly for two reasons. First, asexuals should enjoy various growth benefits because they seemingly rid themselves of the many inefficiencies of sexual reproduction—the so-called costs of sex. Second, there seems to be no lack of asexual origins because losses of sexual reproduction have been described in almost every larger eukaryotic taxon. Current attempts to resolve this paradox concentrate on a few hypotheses that provide universal benefits that would compensate for these costs and give sexual reproduction a net advantage.

Abstract:
Facultative sex combines sexual and asexual reproduction in the same individual (or clone) and allows for a large diversity of life-history patterns regarding the timing, frequency and intensity of sexual episodes. In addition, other life-history traits such as a diapause stage may become linked to sex. Here, we develop a matrix modelling framework for addressing the cost of sex in facultative sexuals, in constant, periodic and stochastically fluctuating environments. The model is parametrized using life-history data from Brachionus calyciflorus , a facultative sexual rotifer in which sex and

Abstract:
Oral health does not exist in a silo. The mouth-body connection is a biological aspect of physical wellbeing that exists alongside the social and political drivers of whole-person health. Lesbian, gay, bisexual, transgender, queer, intersex, and agender/ asexual people, and people of other marginalized gender or sexual identities (LGBTQIA+), have experienced historical exclusion from healthcare systems perpetuated by chronic stigma. Ongoing discrimination, cultural insensitivity, and blatant homophobia/transphobia among healthcare staff results in poor health outcomes, including oral health. T

Abstract:
Humanitarian crises affect diverse populations in complex ways, often exacerbating pre-existing vulnerabilities and inequalities. Among those disproportionately impacted are LGBTQIA+ (lesbian, gay, bisexual, transgender, queer, intersex, asexual and other SOGIESC – sexual orientations, gender identities, and sex characteristics) individuals and communities. In the Philippines – a country that frequently experiences humanitarian emergencies, such as pandemics, conflict, and environmental hazards – LGBTQIA+ people face unique challenges. Both LGBTQIA+ people and the challenges they face are ofte

Abstract:
A fundamental problem in biology is to understand how fertilization initiates reproductive development. During plant reproduction, one sperm cell fuses with the egg to form an embryo, whereas a second sperm cell fuses with the adjacent central cell nucleus to form the endosperm tissue that supports embryo and/or seedling development. To understand the mechanisms that initiate reproduction, we have isolated mutants of Arabidopsis that allow for replication of the central cell and subsequent endosperm development without fertilization. In this project we have cloned the MEA gene and showed that

Abstract:
Mango is one of the most important fruit crops. However, the biology of this fruit tree is under studied. The lack of genetic and genomic resources has limited progress in mango research and breeding. Several research groups have recently started developing genomic tools for mango by creating transcriptome and genomic data. Sexual reproduction in plants is the main pathway for the creation of new genetic combinations. In modern agriculture, breeders exploit the genetic diversity generated through sexual reproduction to develop elite cultivars; however, these cultivars require genetic stabiliza

Full text
Abstract:
Porphyra species (commonly known as ‘nori’ or ‘purple laver’) are edible red seaweeds rich in proteins, vitamins and other highly valued biogenic compounds. For years Porphyra has been cultured using seeded nets extended in the open sea, and its biomass consumed primarily in the Far East. While demands for international markets have increased steadily at an average of 20% per year, supplies are on the verge and not expected to meet future demands. Alternatively, land-based cultivation of seaweed has become attractive in the mariculture industry since (1) important growth parameters can be cont
