Life-history traits and density dependence in metapopulations of a tropical moss: a monoicous species that is almost dioicous.
Publication Type: Academic Journal
Source(s): Oecologia [Oecologia] 2023 Feb; Vol. 201 (2), pp. 287-298. Date of Electronic Publication: 2022 Dec 15.
Abstract: Life-history traits, such as reproductive allocation, sexual expression, sex ratio, and reproductive success, are central aspects of a species' ecology and evolution. For example, bias in male and female sex expression may play a large role in determin...
Evidence for stronger discrimination between conspecific and heterospecific mating partners in sexual vs . asexual female freshwater snails.
Publication Type: Academic Journal
Source(s): PeerJ [PeerJ] 2022 Nov 24; Vol. 10, pp. e14470. Date of Electronic Publication: 2022 Nov 24 (Print Publication: 2022).
Abstract: Once-useful traits that no longer contribute to fitness tend to decay over time. Here, we address whether the expression of mating-related traits that increase the fitness of sexually reproducing individuals but are likely less useful or even costly to...
Distinct patterns of gene expression during regeneration and asexual reproduction in the annelid Pristina leidyi.
Publication Type: Academic Journal
Source(s): Journal of experimental zoology. Part B, Molecular and developmental evolution [J Exp Zool B Mol Dev Evol] 2022 Nov; Vol. 338 (7), pp. 405-420. Date of Electronic Publication: 2022 May 23.
Abstract: Regeneration, the ability to replace lost body parts, is a widespread phenomenon in the animal kingdom often connected to asexual reproduction or fission, since the only difference between the two appears to be the stimulus that triggers them. Both dev...
Soil fungi invest into asexual sporulation under resource scarcity, but trait spaces of individual isolates are unique.
Publication Type: Academic Journal
Source(s): Environmental microbiology [Environ Microbiol] 2022 Jul; Vol. 24 (7), pp. 2962-2978. Date of Electronic Publication: 2022 Apr 27.
Abstract: During the last few decades, a plethora of sequencing studies provided insight into fungal community composition under various environmental conditions. Still, the mechanisms of species assembly and fungal spread in soil remain largely unknown. While m...
Asymmetric density-dependent competition does not contribute to the maintenance of sex in a mixed population of sexual and asexual Potamopyrgus antipodarum.
Publication Type: Academic Journal
Source(s): Journal of evolutionary biology [J Evol Biol] 2022 Jul; Vol. 35 (7), pp. 1012-1019. Date of Electronic Publication: 2022 Jun 01.
Abstract: Asexual reproduction is expected to have a twofold reproductive advantage over sexual reproduction, owing to the cost of producing males in sexual subpopulations. The persistence of sexual females, thus, requires an advantage to sexual reproduction, at...
Hazardous Loss of Genetic Diversity through Selective Sweeps in Asexual Populations.
Publication Type: Academic Journal
Source(s): The American naturalist [Am Nat] 2022 Mar; Vol. 199 (3), pp. 313-329. Date of Electronic Publication: 2022 Jan 11.
Abstract: AbstractWith the twofold cost of sex, derived asexual organisms have an immediate reproductive advantage over their sexual sisters. Yet the "twiggy" phylogenetic distribution of asexual lineages implies that they become extinct relatively quickly over ...
The Circadian Clock, Nutritional Signals and Reproduction: A Close Relationship.
Publication Type: Academic Journal
Source(s): International journal of molecular sciences [Int J Mol Sci] 2023 Jan 12; Vol. 24 (2). Date of Electronic Publication: 2023 Jan 12.
Abstract: The circadian rhythm, which is necessary for reproduction, is controlled by clock genes. In the mouse uterus, the oscillation of the circadian clock gene has been observed. The transcription of the core clock gene period ( Per ) and cryptochrome ( Cry ...
Parthenogenesis in dipterans: a genetic perspective.
Publication Type: Academic Journal
Source(s): Proceedings. Biological sciences [Proc Biol Sci] 2023 Mar 29; Vol. 290 (1995), pp. 20230261. Date of Electronic Publication: 2023 Mar 22.
Abstract: Parthenogenesis has been documented in almost every phylum of animals, and yet this phenomenon is largely understudied. It has particular importance in dipterans since some parthenogenetic species are also disease vectors and agricultural pests. Here, ...
Impact of energy availability and physical activity on variation in fertility across human populations.
Publication Type: Academic Journal
Source(s): Journal of physiological anthropology [J Physiol Anthropol] 2023 Feb 24; Vol. 42 (1), pp. 1. Date of Electronic Publication: 2023 Feb 24.
Abstract: Human reproduction is energetically costly, even more so than other primates. In this review, we consider how the energy cost of physical activity impacts reproductive tasks. Daily energy expenditure appears to be constrained, leading to trade-offs bet...
Editorial: Neuroendocrine regulation of feeding and reproduction in fish.
