Molecular Ecology, Volume 35, Issue 12, June 2026.ABSTRACT Early‐life telomere length can be an integrated and accessible biomarker of lifetime fitness. Telomere length can result from complex interactions between heritable genetic variation, inherited gametic variation and accumulated environmental effects acting on individuals and parents.

Beyond sex allocation : the role of mating systems in sexual selection in parasitoid wasps [PDF]
, 2014 Funding: UK NERC Doctoral Training GrantDespite the diverse array of mating systems and life histories which characterise the parasitic Hymenoptera, sexual selection and sexual conflict in this taxon have been somewhat overlooked.

Manifold limits on seed production by individual flowering plants
American Journal of Botany, Volume 113, Issue 5, May 2026.Abstract Premise Historically, angiosperm seed production has been considered to be either pollen or resource limited. However, seed production involves more than pollen and seed resources and typically involves multiple ovules in multiple flowers. Therefore, various constraints may act simultaneously. Methods Proportional components of seed production

Feminist Anthropology, Volume 7, Issue 1, May 2026.Abstract This article examines how mobility restrictions imposed by governments during the COVID‐19 pandemic intensified reproductive and mobility injustices. It traces shifting configurations of privilege and inequality within marginalized groups whose reproductive desires remain legally and socially unrecognized.

Regulation of the maternal-to-embryonic transition in "C. elegans" [PDF]
, 2012 Reproduction is a fundamental process of life which allows the survival of each species through the birth of young species members. Several modes of reproduction evolved and are classified into sexual and asexual reproduction.

Beyond the Barrier: Epithelial Cells as Immune Sentinels in the Female Genital Tract
American Journal of Reproductive Immunology, Volume 95, Issue 5, May 2026.ABSTRACT Epithelial cells (ECs) of the female genital tract (FGT) serve as an essential barrier and the first line of defense against sexually transmitted pathogens. Beyond providing a physical barrier, these cells actively contribute to immune responses through pathogen recognition, cytokine release, and modulation of adaptive immune responses ...

Luteinizing hormone receptor knockout mouse: What has it taught us?
Andrology, Volume 14, Issue 4, Page 1017-1028, May 2026.Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

Females benefit from mating with different males in the scorpionfly Panorpa cognata [PDF]
, 2006 The adaptive significance of female polyandry has become a recurrent subject of recent theoretical and empirical research. It has been argued that in addition to direct benefits, such as nuptial gifts or an adequate sperm supply, females may gain genetic
