Testes size increases with sperm competition risk and intensity in bony fish and sharks

Behavioral Ecology, 2018
Female multiple mating provides the opportunity for sexual selection to continue after gamete release, generating strong selection on male reproductive traits. In particular, in species where female multiple mating is common, males are expected to invest

Mechanistic Insights Into Photocatalytic Materials for Toxic Pollutants: Environmental Remediation of Personal Care Products

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Photocatalytic materials have emerged as promising solutions for environmental applications due to their ability to degrade organic pollutants under sunlight or artificial light. In this review, recent progress on the photocatalytic materials used for the degradation of pharmaceutical personal care products (PPCPs) in environmental ...

A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Unique sperm haplotypes are associated with phenotypically different sperm subpopulations in Astyanax fish

BMC Biology, 2018
Background The phenotypes of sperm are generally believed to be under the control of the diploid genotype of the male producing them rather than their own haploid genotypes, because developing spermatids share cytoplasm through intercellular bridges ...

Pharmacokinetics, pharmacodynamics and safety of vutiglabridin after multiple oral administrations in healthy female and obese subjects

British Journal of Clinical Pharmacology, EarlyView.
Aims Vutiglabridin (HSG4112) is a novel drug under clinical development for antiobesity treatment. This study aimed to evaluate the pharmacokinetics (PKs) and safety of vutiglabridin after multiple oral administrations in healthy Korean female and obese subjects and explore short‐term pharmacodynamic (PD) responses.

Sperm Competition Risk and Sexual Coercion Predict Copulatory Duration in Humans

Evolutionary Psychology, 2015
A man whose romantic partner is sexually unfaithful is at risk of sperm competition and cuckoldry—unwitting investment in offspring to whom he is genetically unrelated.

Sperm traits negatively covary with size and asymmetry of a secondary sexual trait in a freshwater crayfish. [PDF]

PLoS ONE, 2012
In species where females mate promiscuously, the reproductive success of males depends both on their ability to acquire mates (pre-copulatory sexual selection) and ability of their ejaculates to outcompete those of other males (post-copulatory sexual ...

Gamete evolution and sperm numbers: sperm competition versus sperm limitation [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2014
Both gamete competition and gamete limitation can generate anisogamy from ancestral isogamy, and both sperm competition (SC) and sperm limitation (SL) can increase sperm numbers. Here, we compare the marginal benefits due to these two components at any given population level of sperm production using the risk and intensity models in sperm economics. We

The impacts of biological invasions

Biological Reviews, EarlyView.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological
