European Journal of Entomology, 2014 Many species of lady beetles are highly promiscuous and females mate repeatedly even when not sperm-limited. We quantified female reproductive success and progeny development in Hippodamia convergens using a laboratory experiment designed to test whether

Scientific Reports, 2023 Although the effects of paternal exposure to insults on the offspring received limited attention in the past, it is currently gaining interest especially after understanding the mechanisms which may mediate such exposure effects.

Evidence of maternal and paternal age effects on speed in thoroughbred racehorses
Royal Society Open Science, 2022 Effects of parental age on offspring viability have been reported in a wide range of species. However, to what extent parental age influences offspring traits beyond viability remains unclear. Moreover, previous research has primarily focused on maternal

Inter‐ and Transgenerational Effects of Paternal Exposure to Inorganic Arsenic
Advancement of science, 2021 The rise of metabolic disorders in modern times is mainly attributed to the environment. However, heritable effects of environmental chemicals on mammalian offsprings' metabolic health are unclear.

Early life lessons: The lasting effects of germline epigenetic information on organismal development
Molecular Metabolism, 2020 Background: An organism's metabolic phenotype is primarily affected by its genotype, its lifestyle, and the nutritional composition of its food supply.

Ecology and Evolution, 2021 We investigate the evolution of a gene for paternal care, with pleiotropic effects on male mating fitness and offspring viability, with and without extrapair copulations (EPCs).

eLife, 2017 Exposing male mice to nicotine or cocaine enables their male offspring to cope with high doses of either, which suggests that such paternal effects are generic, rather than being a response to a specific type of stress.

The effects of advanced paternal age on fertility
Asian Journal of Andrology, 2013 Modern societal pressures and expectations over the past several decades have resulted in the tendency for couples to delay conception. While women experience a notable decrease in oocyte production in their late thirties, the effect of age on spermatogenesis is less well described.

The Paternal Age Effect: A Multifaceted Phenomenon
Biology of Reproduction, 2013 Birth rates for older fathers have increased 30% since 1980. When combined with the increased risk for genetic and multifactorial disorders in children conceived by older fathers, paternal age has become an important health issue for modern society. Laboratory research in this area has been minimal, perhaps because of significant experimental barriers,
