Motivational Drive in Non-copulating and Socially Monogamous Mammals

Frontiers in Behavioral Neuroscience, 2019
Motivational drives guide behaviors in animals of different species, including humans. Some of these motivations, like looking for food and water, are crucial for the survival of the individual and hence for the preservation of the species.

Sexual reproduction with variable mating systems can resist asexuality in a rock–paper–scissors dynamics [PDF]

Royal Society Open Science, 2015
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.

Michel Henry's Transcendental Asexuality

Aisthema: International Journal, 2022
Since his earliest speculations in The Essence of Manifestation (1963), Michel Henry’s radical phenomenology has highlighted the importance of the flesh and eros as central figures of the duality of appearance.

Genetic variation in the brooding brittle-star: a global hybrid polyploid complex?

Royal Society Open Science
The widespread and abundant brooding brittle-star (Amphipholis squamata) is a simultaneous hermaphrodite with a complex mitochondrial phylogeography of multiple divergent overlapping mtDNA lineages, high levels of inbreeding or clonality and unusual ...

Splenic Tropism and Spleen‐Modulated Systemic Inflammation in Acute Plasmodium vivax Malaria

American Journal of Hematology, EarlyView.
ABSTRACT In chronic Plasmodium vivax (Pv) infection, the spleen accounts for over 98% of total‐body parasite biomass. Whether splenic tropism also occurs in acute infection and how the spleen influences pathogenesis have not been systematically explored. In Papua, Indonesia, we compared clinical and hematology data in 24 spleen‐intact and 25 previously

YOU DON’T HAVE TO HAVE SEX: COUNSELLING FIELDS AND MANDATORY SEXUALITY [PDF]

, 2022
Asexuality, and by extension people’s right to not have sex, is contentious ground. Psychology’s conception of asexuality perpetuates a system of oppression called mandatory sexuality.

Molecular methods for differentiating Phragmites australis subspecies and identification of hybrid stands in the Upper Midwestern United States

Applications in Plant Sciences, EarlyView.
Abstract Premise In North America, Phragmites australis (common reed) has drawn a great deal of research attention. Non‐native P. australis subsp. australis is a noxious weed that has locally displaced native P. australis subsp. americanus in some areas.

Pharmacometric evaluation of pre‐referral rectal artesunate in children with severe malaria

British Journal of Clinical Pharmacology, EarlyView.
Aims Parenteral artesunate is the preferred first‐line treatment for severe malaria. Pre‐referral rectal artesunate suppositories are recommended where parenteral treatment is inaccessible. In this study, we compared dihydroartemisinin exposure and model‐predicted early parasite clearance following rectal artesunate and intravenous artesunate in ...

Asexual Reproduction Does Not Apparently Increase the Rate of Chromosomal Evolution: Karyotype Stability in Diploid and Triploid Clonal Hybrid Fish (Cobitis, Cypriniformes, Teleostei). [PDF]

PLoS ONE, 2016
Interspecific hybridization, polyploidization and transitions from sexuality to asexuality considerably affect organismal genomes. Especially the last mentioned process has been assumed to play a significant role in the initiation of chromosomal ...

Dynamic formation of asexual diploid and polyploid lineages: multilocus analysis of Cobitis reveals the mechanisms maintaining the diversity of clones. [PDF]

PLoS ONE, 2012
Given the hybrid genomic constitutions and increased ploidy of many asexual animals, the identification of processes governing the origin and maintenance of clonal diversity provides useful information about the evolutionary consequences of interspecific
