A membrane-associated progesterone-binding protein, 25-Dx, is regulated by progesterone in brain regions involved in female reproductive behaviors.
(Proc Natl Acad Sci U S A, 2000-11-07)The ventromedial hypothalamus (VMH) plays a central role in the regulation of the female reproductive behavior lordosis, a behavior dependent upon the sequential activation of receptors for the ovarian steroid hormones estradiol ... -
A widespread chromosomal inversion polymorphism contributes to a major life-history transition, local adaptation, and reproductive isolation.
(PLoS Biol, 2010-09-28)The role of chromosomal inversions in adaptation and speciation is controversial. Historically, inversions were thought to contribute to these processes either by directly causing hybrid sterility or by facilitating the ... -
Alcohol, drugs, caffeine, tobacco, and environmental contaminant exposure: reproductive health consequences and clinical implications.
(Critical reviews in toxicology, 2010-08)Reproductive function and fertility are thought to be compromised by behaviors such as cigarette smoking, substance abuse, and alcohol consumption; however, the strength of these associations are uncertain. Furthermore, ... -
Biological and Physical Factors Affecting the Natural History and Evolution of Encapsulated Development
(2016)The evolution of reproductive strategies involves a complex calculus of costs and benefits to both parents and offspring. Many marine animals produce embryos packaged in tough egg capsules or gelatinous egg masses attached ... -
Chronic microfiber exposure in adult Japanese medaka (Oryzias latipes).
(PloS one, 2020-01)Microplastic fibers (MFs) pollute aquatic habitats globally via sewage release, stormwater runoff, or atmospheric deposition. Of the synthetic MFs, polyester (PES) and polypropylene (PP) are the most common. Field studies ... -
Comparative genomics reveals insights into avian genome evolution and adaptation.
(Science, 2014-12-12)Birds are the most species-rich class of tetrapod vertebrates and have wide relevance across many research fields. We explored bird macroevolution using full genomes from 48 avian species representing all major extant clades. ... -
Diversity of ageing across the tree of life.
(Nature, 2014-01-09)Evolution drives, and is driven by, demography. A genotype moulds its phenotype's age patterns of mortality and fertility in an environment; these two patterns in turn determine the genotype's fitness in that environment. ... -
Evolution. Getting to the root of aging.
(Science, 2012-11-02) -
Four reasons for scepticism about a human major transition in social individuality.
(Philosophical transactions of the Royal Society of London. Series B, Biological sciences, 2023-03)The 'major transitions in evolution' are mainly about the rise of hierarchy, new individuals arising at ever higher levels of nestedness, in particular the eukaryotic cell arising from prokaryotes, multicellular individuals ... -
Genetic and phenotypic characterization of a hybrid zone between polyandrous Northern and Wattled Jacanas in Western Panama.
(BMC evolutionary biology, 2014-11)<h4>Background</h4>Hybridization provides a unique perspective into the ecological, genetic and behavioral context of speciation. Hybridization is common in birds, but has not yet been reported among bird species with a ... -
Genetic origins of social networks in rhesus macaques.
(Scientific reports, 2013-01-09)Sociality is believed to have evolved as a strategy for animals to cope with their environments. Yet the genetic basis of sociality remains unclear. Here we provide evidence that social network tendencies are heritable in ... -
How Female-Female Competition Affects Male-Male Competition: Insights into Postcopulatory Sexual Selection from Socially Polyandrous Species.
(The American naturalist, 2023-03)AbstractSexual selection is a major driver of trait variation, and the intensity of male competition for mating opportunities has been linked with sperm size across diverse taxa. Mating competition among females may also ... -
Incubation temperature effects on hatchling performance in the loggerhead sea turtle (Caretta caretta).
(PloS one, 2014-01)Incubation temperature has significant developmental effects on oviparous animals, including affecting sexual differentiation for several species. Incubation temperature also affects traits that can influence survival, a ... -
Mechanisms that ensure monogamous mating in Saccharomyces cerevisiae.
(Molecular biology of the cell, 2021-04)Haploid cells of the budding yeast Saccharomyces cerevisiae communicate using secreted pheromones and mate to form diploid zygotes. Mating is monogamous, resulting in the fusion of precisely one cell of each mating type. ... -
Multiple phenotypic changes in mice after knockout of the B3gnt5 gene, encoding Lc3 synthase--a key enzyme in lacto-neolacto ganglioside synthesis.
(BMC Dev Biol, 2010-11-18)BACKGROUND: Ganglioside biosynthesis occurs through a multi-enzymatic pathway which at the lactosylceramide step is branched into several biosynthetic series. Lc3 synthase utilizes a variety of galactose-terminated glycolipids ... -
Natural hybridization between genera that diverged from each other approximately 60 million years ago.
(Am Nat, 2015-03)A fern from the French Pyrenees-×Cystocarpium roskamianum-is a recently formed intergeneric hybrid between parental lineages that diverged from each other approximately 60 million years ago (mya; 95% highest posterior density: ... -
Parental dietary seleno-L-methionine exposure and resultant offspring developmental toxicity.
(Aquatic toxicology (Amsterdam, Netherlands), 2016-01)Selenium (Se) leaches into water from agricultural soils and from storage sites for coal fly ash. Se toxicity causes population and community level effects in fishes and birds. We used the laboratory aquarium model fish, ... -
Public goods and procreation.
(Monash Bioeth Rev, 2014-09)Procreation is the ultimate public goods problem. Each new child affects the welfare of many other people, and some (but not all) children produce uncompensated value that future people will enjoy. This essay addresses challenges ... -
Reproduction and Growth in a Murine Model of Early Life-Onset Inflammatory Bowel Disease.
(PLoS One, 2016)Studies in transgenic murine models have provided insight into the complexity underlying inflammatory bowel disease (IBD), a disease hypothesized to result from an injurious immune response against intestinal microbiota. ... -
Reproduction and population growth in free-ranging mantled howling monkeys.
(Am J Phys Anthropol, 1980-07)Free-ranging mantled howling monkey (Alouatta palliata Gray) females experienced a regular estrus cycle averaging 16.3 days, demonstrated sexual skin changes, and participated in multiple matings before becoming pregnant. ...
