Journal of Periodontology, EarlyView.Abstract Background This study investigates the impact of disruptions in testosterone levels on bone remodeling, root resorption, and periodontal ligament (PDL) during orthodontic tooth movement (OTM) in a pubertal male rat model. Methods Testosterone deficiency was induced through orchiectomy, and the anabolic‐androgenic steroid (AAS, testosterone ...

Sophisticated sperm allocation in male fowl [PDF]
, 2003 When a female is sexually promiscuous, the ejaculates of different males compete for the fertilization of her eggs; the more sperm a male inseminates into a female, the more likely he is to fertilize her eggs.

Accessory gland size increases with sperm competition intensity in Cataglyphis desert ants
Frontiers in Ecology and EvolutionIn many species, females have multiple mates, whose sperm compete for paternity. Males may subsequently invest in the increased production of sperm and/or seminal fluid. The latter is a complex mixture of proteins, peptides, and other compounds generated

Heritable determinants of male fertilization success in the nematode [PDF]
, 2011 Background Sperm competition is a driving force in the evolution of male sperm characteristics in many species. In the nematode Caenorhabditis elegans, larger male sperm evolve under experimentally increased sperm competition and larger male sperm ...

Innate immunity shapes the persistent transmission of plant viruses by insect vectors
New Plant Protection, EarlyView.In this review, we focus on two key aspects of the virus–vector interplay: (1) persistently transmitted viruses utilize host factors to overcome transmission barriers; and (2) molecular recognition activates antiviral immunity and subsequent viral counter‐defense. Understanding these interactions offers critical insights for developing novel strategies

PLoS ONE, 2008 When females are sexually promiscuous, the intensity of sperm competition for males depends on how many partners females mate with. To maximize fitness, males should adjust their copulatory investment in relation to this intensity. However, fitness costs

Sperm phenotypic plasticity in a cichlid: a territorial male's counterstrategy to spawning takeover [PDF]
, 2017 Studies of sperm competition in species with alternative reproductive tactics (ARTs) often pay attention to the differences in investments in sperm between sneakers facing a higher sperm competition risk and bourgeois males facing a lower risk.

Oikos, EarlyView.Animals gather information about their surroundings, including their social environment, using a wide range of sensory modalities. Variation in reception, processing and interpretation of information (cues or signals) can lead to differences in how individuals perceive their local environment. Yet, how individual differences in environmental perception
